With that, let me now turn the call over to Eric. Eric? Speaker 200:01:42Thank you, Anne, and welcome, everyone. 2023 was a year of many great achievements for Travir as we worked towards our goal of breaking down barriers and treating rare diseases with historically little innovation. At the start of 2023, we gained the 1st approval from our pipeline delivering sparsentan or silspari as the first and only non immunosuppressive treatment option for people living with IgA nephropathy or IgAN. For decades, people living with IgAN, most of whom are diagnosed in their 20s 30s and on average face kidney failure in 10 years and limited treatment options. We are proud to help lead the growing evolution of the treatment paradigm that we believe will ultimately see patients get diagnosed and initiate treatment earlier and where physicians will ultimately utilize SPILsparri as a foundational treatment with its superior proteinuria reduction and accrual of kidney preservation benefit. Speaker 200:02:38Following the grant of accelerated approval, Our team quickly initiated our comprehensive commercial launch plan and worked throughout the year to lay a strong foundation for a PULSARRI uptake. I am very pleased with our results. We continue to make substantial progress in physician demand, payer coverage and revenue, the key aspects of the launch. Of note, VILspari is the only recent launch in the rare kidney space that has seen consistent growth in demand each quarter in its 1st year. And we saw a meaningful inflection in net product sales to close out 2023. Speaker 200:03:13Last year, we encountered a challenge in our pursuit of a better outlook for the FSGS community. Specifically, the DUPLEX study of sparsentan in FSGS did not achieve the results we had hoped. And following our FDA engagement, it was clear we would not be in a position to submit an sNDA at that time based on the DUPLEX results alone. I'm incredibly grateful and proud of how our colleagues at Trevir learned and quickly adjusted. We moved quickly to align our investment in this program, implement a strategic restructuring of our organization to focus our resources and concentrate our efforts to collaborate with regulators with the goal of identifying regulatory path forward in the future. Speaker 200:03:56As for pegmatinase development program for classical homocystinuria or HCU, We achieved important milestones in 2023. Globally, we believe there are 7000 to 10000 patients diagnosed with HCU who are not in full control of their homocysteine levels. With better diagnoses and a future where an effective treatment is available, we believe this may grow by 50% or more over time. Last year, we generated additional exciting data from our Phase to COMPOSE study, which further demonstrates the potential for pegdubatinib to become the only disease modifying therapy for HCU. With these data, we worked closely with regulators to align on a Phase 3 program, utilizing total homocysteine reduction as a primary endpoint and initiated that study before year end. Speaker 200:04:45All of our efforts last year positioned us to start 2024 with focus and a plan for execution across the board. Strong launch performance in Valspari remains our top priority for 2024 And we expect the momentum in our launch from the second half of twenty twenty three will continue into the New Year. We are also executing on 3 additional priorities aimed at broadening access to Vilspari. Of note, we are on track to submit our sNDA this quarter to support version of Vilspari from accelerated approval to full approval for IGAN in the U. S. Speaker 200:05:19Together with our partner CSLV4, We expect an opinion on conditional approval of Vilspari in Europe from CHMP later this quarter. We're optimistic that this will be positive. And with our recent agreement with Rinalis, we are looking forward to aiding their development plans to ultimately enable access to VOSPARI in Japan and other regions in Asia, where IgAN is an even more prevalent disease and leading cause of kidney failure. And importantly, we are excited about the opportunity we have with pigdevatinase, our novel investigational enzyme replacement therapy being evaluated for the treatment of classical homocystinuria or HCU. In 2024, our focus will be on enrolling our Phase III HARMONY trial and raising awareness of the need for innovative treatments for this rare disorder. Speaker 200:06:07Let me now turn the call over to Jula for a clinical update. Jula? Speaker 300:06:11Thank you, Eric, and good afternoon. I am very pleased with the progress made on our clinical and medical affairs initiatives in 2023. With our achievements last year, we are well positioned to ultimately deliver 2 new treatment standards in rare diseases with limited options available. At Borfil Spari, we completed the 2 year double blind dosing periods for our studies in FSGS and IgAN. It's important to highlight that our studies are the only ones in the space that use a maximally optimized active comparator, setting the bar highest in the field. Speaker 300:06:48The results, which clearly demonstrated robust proteinuria reduction and preservation of kidney function in IgAN were simultaneously presented as late breaker presentations at ASN and published in world renowned medical journals, The Lancet and New England Journal of Medicine. Following those data presentations, we have received positive feedback from nephrologists about the foundational role that ZILFARI can play in long term kidney function preservation for patients with IgA nephropathy. What has resonated with nephrologists is that ZILFARI is the only approved non immunosuppressive treatment for IgAN and it's the only molecule that works by simultaneously blocking the 2 key pathogenic pathways in the kidney, endothelin 1 and angiotensin 2 that both work together to drive damage and kidney function loss. ZILFARI's dual mechanism of action is critical to inhibiting the damaging pathways in the kidney in order to achieve sustained proteinuria reduction and long term kidney function preservation that accrues over time. Unlike intermittent therapies, which may have short term benefits on kidney function, ZILFARI demonstrated a long term accrual of benefit on eGFR. Speaker 300:08:06In the PROTECT study, at 1 year, there was a 1.7 ml per minute Favorable effect on absolute eGFR with VILSPARI compared to maximally titrated erbasartan. And that benefit increased to 3.7 ml per minute greater eGFR at 2 years. Importantly, The rate of loss of kidney function in year 2 compared to year 1 was significantly slower for Vilspari treated patients, suggesting a potential additive benefit with longer term treatment. This year over year accrual of benefit is important for a patient who has ongoing kidney injury over their lifetime and may otherwise be facing kidney failure less than 10 years from diagnosis. Our 2 year data from the PROTECT study in IVAN shows that Sulfari is superior to historical RAF inhibitors and it's safe for chronic use, which is critical in treating patients for life. Speaker 300:09:07Community and academic nephrologists are continuously highlighting to us the Early clinical experience with ZILSPARI, where they see significant reductions in proteinuria and the ability to safely use FILFARI with our patients chronically. We believe this cements the role that FILFARI can play by replacing RAS inhibitors as foundational care for those at risk of rapid disease progression due to uncontrolled proteinuria. Following the positive results from PROTECT, We successfully completed a pre NDA meeting with FDA to discuss our plans to submit an sNDA to convert Filspari from accelerated approval to full approval for IgAN. Importantly, we aligned with the FDA on the data analysis to support our submission and to support potential broader labeling. I'm pleased to report that we remain on track to submit the sNDA this quarter. Speaker 300:10:01We are at an exciting juncture in the evolution of the IgAN treatment paradigm. We believe that nephrologists are focused on treating the damage in the kidney and then preventing further damage systemically. Our goal is to ultimately have VILFARI used as the foundational care in IgAN, essentially replacing the historical role of RAS inhibitors and then other medicines can be added as needed. As this evolution continues, there are a number of factors that we expect will help Vilspari achieve this goal. With a full approval from FDA, we would expect a broader label that reflects the full study population and the results. Speaker 300:10:39This would provide nephrologists and patients with greater flexibility to choose Vilspari when seeking treatment options that can provide long term kidney function preservation. Additionally, we believe Vilspari's likely inclusion in the soon to be released KDIGO guidelines should further standardize use of Vilspari for the nephrology community and potentially result in earlier treatment. As positioned in up to date and recent peer reviewed IGAN treatment article, We anticipate Vilspari will be described as a foundational treatment in the KDIGO guidelines. We also believe that the proteinuria target for treating IgANT overall will be lowered, which would support earlier diagnosis, more aggressive treatment to avoid long term damage as well as combination treatment in the future. Furthermore, later this year, we expect to generate longer term data from our ongoing Spartacus and SPARTAN studies, which are designed to show Filspari can be safely used in combination with other medicines such as SGLT2 inhibitors and that patients may benefit from earlier use of Filspari. Speaker 300:11:46Such data will further support the progress towards Filspari achieving foundational care. Beyond the U. S, we have continued to work closely with our partners at CSL Vifor on the conditional marketing authorization application that is currently under evaluation in the EU. Following a procedural clock stop to review the 2 year data, we believe that we are well positioned for a positive CHMP opinion this quarter and an approval decision next quarter. Beyond the CSLV4 territories, our recent agreement with Renalis provides Filspari with a regulatory pathway that has the potential to deliver Filspari across a number of Asian countries in the coming years. Speaker 300:12:28Overall, we are very pleased with the important groundwork laid in 2023 and we see a clear roadmap for increased utilization of DYOSPARI for IGAN in 2024 and beyond. Turning briefly to FSGS. With no approved therapies for tens of thousands of patients with this condition and the high rate of progression to kidney failure, we are committed to trying to find a path forward for sparsentan and FSGS. We are taking a measured approach to evaluating our data sets and working with the community to re engage the FDA later this year Toward the goal of ultimately being able to submit to have an FSGS indication added to the Filsparin label, we anticipate being able to provide an update on this work late in the As Eric highlighted earlier, our enthusiasm in pegtobatinase continues to grow. We were pleased to achieve alignment with regulators on the design of our Phase 3 program and to reach our goal of initiating the Phase 3 HARMONY study before year end. Speaker 300:13:30This study employs an innovative design with measurements very similar to our highly successful Phase III study, which we believe provides a high probability of success as a registration enabling study. The Phase III HARMONY study is designed up to 70 patients with HCU and evaluate change in total homocysteine from baseline to week 6 to 12 as the primary endpoint. This is the measurement for which we saw a 67% reduction in the highest dose cohort in the COMPOSETI. Patients will be followed in the double blind period for 24 weeks in total to establish durability of effect and a robust safety database. To maximize consistency, there is a 10 week screening and diet stabilization period prior to randomization in Harmony. Speaker 300:14:20And patients who complete the full double blind period will be eligible to enroll into an open label study called ENSEMBLE, where there is a protocolized diet liberalization substudy for eligible patients who have well controlled total homocysteine. This portion of the study is designed to generate data throughout the life of the program and we believe it will ultimately be able to help patients understand Avant may be able to increase protein intake while taking pegtobatinase, a key area of need for patients living with HCU. As we move through 2024, we will be focused on ramping up enrollment in the HARMONY study and scaling our pegtubatinase manufacturing activities to support the full program and future commercialization. We look forward to top line data in 2026 with the potential approval in 2027. I'll now turn the call over to Peter for the commercial update. Speaker 300:15:13Peter? Speaker 400:15:15Thank you, Lat. Looking back on 2023, We made robust progress on what we have outlined during our launch call in February last year. Precision feels powering iGAM as the future foundational care for patients at risk of rapid progression through educating our nephrology targets, securing broad access and ensuring a positive initial sales by experience for patients and physicians. And I'm really proud on the progress our commercial team has made in the past year, especially while adapting to the initial promotional restrictions that come with accelerated approval and an unexpected advanced program for liver monitoring. By the end of 2023, we reached 5,700 nephrologists with our sales team in regular face to face educational interactions. Speaker 400:16:03That is 95% of our target base of 6,000 nephrologists that we believe treat about 85% of the addressable IgM patients in the U. S. These efforts resulted in strong and steadily increasing demand with increasing breadth and depth of prescribing nephrologists. In particular, in the Q4, we built strong momentum to fulfill spa in demand, And I couldn't be more pleased with how we ended the year. It was encouraging to see further growth in new patient start forms or PSFs after ASN Kidney Week, where the confirmatory PROTECT study results were presented and published. Speaker 400:16:44Importantly, we also received further validation of the Valsari profile from card leaders, which was evidenced by an increase in key opinion leader prescribers. We ended the 4th quarter with 459 new PFS, which demonstrated quarter over quarter growth for each period in 2023. In fact, this is the first recent rare nephrology product has shown a continuation of growth in demand during each period of the first in the 1st year of launch. In total, we received more than 1450 patient start forms in 2023, which clearly indicates TILSTARI is helping fill a significant need for the nephrology community. On the payer front, We established a strong base allowing broad patient access. Speaker 400:17:33By the end of the year, coverage reached about 70% of U. S. Lives. In the Q4, we added about 180 new FilSpari specific formularies. And overall, More than 1,000 formularies have included Schilzpari with authorization criteria that are generally consistent to the Schilzpari label. Speaker 400:17:54And if we account for plans that didn't yet include Fiospari, but have a clear pathway for coverage, that total is about 89% of U. S. Lives. Following our teams quick adjustments to improve Patient education provides further support for the liver monitoring REMS in the second half of the year. We saw continued progress in our lead measures of REMS certifications in the 1st 14 days after receiving patient start form. Speaker 400:18:24This also led to a growing number of reimbursed patients initiating therapy during the quarter. And we are hearing almost on a daily basis from patients and physicians How impressed they are with the results that they have shared with Celsparium. These results are consistent to what was observed in the PROPECT trial, with rapid and sustained proteinuria reductions with a safety profile similar to ACE inhibitors and ARBs. This is encouraging for patients that started using VILSTARI and likely why we are seeing high compliance rates so far in the lungs. All these accomplishments resulted in a significant increase in net sales party sales. Speaker 400:19:08In the Q4, we reported approximately $15,000,000 in net product sales, which resulted in nearly $30,000,000 for the year. IOLA and IOLA DC also remained steady, contributing approximately $25,000,000 in net product sales in the Q4. We recently learned of an approval of a generic Thiola we see with a narrower label, and we will continue to monitor what impact that may have throughout the year. Overall, we ended 2023 with solid execution, And this provides us with a robust foundation for strong performance in 2024. In fact, in the 1st 6 weeks of the New Year, I'm pleased to see our strong filsparity performance continue. Speaker 400:19:51Our team is ready to show the true potential of filsparity in this new year, And we have multiple inflection points throughout 2024 that provides confidence in continuing growth. Let me highlight the 4 areas that I am particularly excited about in the coming year. 1st, if we achieve full approval as targeted for later this year, We anticipate that an updated and potentially broad label would provide greater support for physicians to prescribe TOSPARI to more of their patients. 2nd, as Jula mentioned earlier, we anticipate that Zolpi will be included in the global PDU guidelines scheduled to be updated this year. This will potentially provide uniform guidance of physicians to choose GLStARRI as an early treatment for their patients. Speaker 400:20:393rd, additionally, if the guideline revision emphasizes earlier intervention by lowering the proteinuria target, It would likely amplify the urgency to diagnose and treat patients earlier. We believe this would increase the number of patients that would be eligible for Filspari. And importantly, a broader label together with a potentially lower target to treat earlier in the guidelines would allow us establish ZOSFARI as the foundational treatment in a larger addressable patient population. And 4th, We expect the additional clinical evidence Ziola highlighted earlier will ultimately provide additional support for physicians to treat earlier RASIL STARI and use it in combination with other available medicines for patients that may need more progressive treatments. With all of this in mind, I could not be more excited about Fiospari's prospects in this new year, and we feel strongly that we are well positioned for significant growth in 2024. Speaker 400:21:40Let me now turn the call over to Chris for the financial update. Chris? Speaker 500:21:46Thank you, Peter, and good afternoon, everyone. Following our Q4 results, we're in a strong financial position. From an operational perspective, we continue to grow revenues and we focus our investments on the ongoing launch of ZOSPARI and IgA nephropathy and the advancement of our Phase III effective adenase program. For the Q4 of 2023, net product sales were $39,900,000 compared to $25,800,000 for the same period in 2022. The increase is attributable to growth in net product sales from the ongoing launch of FOSPARI and IgA nephropathy. Speaker 500:22:16During the quarter, we also recognized $5,100,000 of licensing collaboration revenue, which results in $45,100,000 in total revenue reported for the period compared to $29,300,000 in the same period in 2022. Research and development expenses for the Q4 of 2023 were $59,700,000 compared to $58,100,000 for the same period in 2022. The difference is largely attributable to the continued advancement of our pecdevatinase clinical program, partially offset by reduced investment in our Filspari Phase 3 programs following the readouts from the 2 year endpoints. On a non GAAP adjusted basis, R and D were $55,300,000 for the Q4 of 2023 compared to $52,000,000 for the same period in 2022. Selling, general and administrative expenses for the Q4 of 2023 were $63,600,000 compared to $57,100,000 for the same period in 2022. Speaker 500:23:09The difference is largely attributable to the commercial launch related activities following the accelerated approval of VOSPARI in February of 2023. On a non GAAP adjusted basis, SG and A expenses were $49,700,000 for the Q4 of 2023 compared to $44,300,000 the same period in 2022. During the Q4, we recognized $11,400,000 in restructuring fees related to the strategic reorganization that was announced in December. Total charges related to the reorganization are expected to amount to between $12,000,000 $14,000,000 Total other income net for the Q4 of 2023 was $5,700,000 compared to $1,100,000 in the same period in 2022. The difference is largely attributable to an increase in interest income during the period. Speaker 500:23:53Net loss including from discontinued operations for the Q4 of 2023 was $90,200,000 or $1.18 per basic share compared to a net loss of $65,800,000 or $1.03 per basic share for the same period in 2022. On a non GAAP basis, net loss including from discontinued operations for the Q4 of 2023 was $71,800,000 or $0.94 per basic share compared to a net loss of $46,900,000 or $0.73 per basic share for the same period of 2022. As of December 31, 2023, the company had cash, cash equivalents and marketable securities of $566,900,000 Looking ahead, we expect meaningful growth in net product sales of FOSPAR in 2024 and we look to achieve non GAAP operating expenses below $400,000,000 for the year. We also anticipate meeting milestones with both FOSPHARRI and pepetabadenase that will result in us making expected net payments of approximately $50,000,000 during the year. With our strong balance sheet, the expected growth in TILESPARI revenues and measured investments, We currently expect that our cash balance can support operations into 20 28. Speaker 500:24:58I'll now turn the call back over to Eric for his closing comments. Eric? Speaker 200:25:02Thanks, Chris. We are entering a new phase of growth for Travir. Our organization is well positioned with strong financial foundation to continue advancing TILFARI and pegdovatinase as potential futures treatment standards for their respective rare kidney and metabolic disorders. Moreover, these global markets collectively are projected to exceed $10,000,000,000 in the coming years. Our unrelenting drive is based on our desire to deliver life changing therapies to people affected by IgAN, HCU and potentially FSGS, who historically have had little to no innovation for their condition. Speaker 200:25:41We see near term and long term growth through the following: the continued strong execution of our Filspari launch, the expected conditional approval of sparsentan in the EU and full approval of Vilspari for IGAN in the U. S. With potential broader labeling, updated iGain treatment guidelines and further data generation to reach the growing number of patients in need of a better therapy. Finally, I am particularly excited about the advancement of our development program for pigdubatinase as the only potential disease modifying therapy in a market that is to grow meaningfully over time. This year, we look forward to raising awareness of HCU and enrolling the Phase III HARMONY study with a goal of achieving top line data in 2026. Speaker 200:26:30Let me now turn the call over to Anne to open up the lines for Q and A. Anne? Speaker 100:26:36Thank you, Eric. We can now open the line up for Q and A. Jenny? Operator00:26:42Thank We will now take the first question from the line of Joseph Schwartz From Leerink Partners. Please go ahead. Speaker 600:27:11Great. Thanks very much and congrats on all the progress. I guess I'll ask on, Filspari, how much does the higher hurdle that Filspari had in the PROTECT trial seem to resonate with the prescribing community. Do they appreciate that patients in the control arm were so well managed? Does this impress them or do you have more education to do in order for them to appreciate FilSparis relative to performance and protect? Speaker 200:27:41Joe, thanks so much for the question. Peter, why don't I turn that over to you and perhaps you can also comment on what we saw coming out of ASN where there was Much more discussion about the PROTECT trial and trial design. Speaker 400:27:57Yes. Happy to take that question, Joe. I would say the conversations I've had with physicians, and I think that's also being underlined with the market results that we saw. But if we outline the study design of PROTECT And the understanding of like an active control arm is understood. There's really like great appreciation for the for the very robust results that we have. Speaker 400:28:23You highlighted earlier in the call like 1.7 ml per minute per year improvement. And then in the second year, you saw actually 3.7 ml per minute per year. So an accumulation of benefit over time. And I think that is something that the physicians, If they understand, we signed really speak highly of. Speaker 200:28:44Okay, Julien. Okay, Julien. Speaker 400:28:44If you want to comment. Speaker 200:28:47Thank you, Jill. Jill, is there anything that you'd like to comment from your team engagement with thought leaders on that trial design And the high bar? Speaker 300:28:58Yes. I think it does take some education because all the other trials are comparing to a not fully optimized standard of other patients, which we know historically 50% and really all the other trials aren't Yes, we have a higher hurdle. And so when they initially see the comparison in the slope, most of which they don't look at in their clinical practice, It takes some education to look at the benefit and then also the accrual of benefit that we should see. We only did a 2 year snapshot, but you know that If you have a benefit that's better in year 2 versus year 1, then that's going to continue to improve year over year. So it does take some time, but they get it once they spend time with the data and the information. Speaker 200:29:40Yes. And I think this is going to be Joe, a very important part of why we're eager to have full approval and a label that will allow us to talk about that long term benefit and how the trial design really does help explain why we see such great results throughout the 2 years. Speaker 700:29:58Very helpful. Thanks. Operator00:30:03And our next question is going to come from Greg Harrison from Bank of America. Please go ahead. Speaker 800:30:10Hey guys, good afternoon. Congrats on the progress and thanks for taking the question. Just thinking through the IGAN treatment landscape And when it comes to comparing different treatment options, especially in light of recent data, is it fair to say that the focus for investors should be on the EGFR benefit or is there a better way to think about it? Speaker 200:30:32Greg, thanks so much for the question. I think the very short answer is no, but I'm going to let Jula talk a bit more about what she as a nephrologist and what she's hearing from thought leaders about the evolving treatment landscape and the importance of eGFR and proteinuria. Dula? Speaker 300:30:50Thanks. First, I'll start with proteinuria and eGFR both matter for how we take care of patients, but I'll highlight that proteinuria is really critical for nephrologists, for patients and for regulators We're evaluating and looking at risk as well as response to treatment over time as the proteinuria changes can occur more quickly versus the GFR changes require many years to show effect. And I would say importantly, multiple data sets show a strong correlation between protein That's why it's an approvable endpoint for accelerated approval. And we also know that we need to get patients as close to normal as possible. When you look at the rates, they still remain at risk if they've got 0.44 grams per day. Speaker 300:31:38So getting patients closer to normal with regards to proteinuria is very important. We saw 1 in 3 patients on FOSPARI in PROTECT achieved complete remission of proteinuria. And FOSPARI shows both reductions in proteinuria and eGFR preservation that accrues over time. So I think all those are important factors to take into consideration. Operator00:32:10I'm sorry, go ahead. Speaker 200:32:13No, no, no, please go ahead. I was just thanking the last Operator00:32:17Okay. Our next question is going to come from Anupam Rama from JPMorgan. Please go ahead. Speaker 200:32:25Hey, guys. Thanks so much for taking the question. A little bit more of a kind of an acute question as we think about in the Q1, any guidance about how we should be thinking about payer reauthorizations and Any seasonality considerations in the quarter? Let me just first say that Peter's team has done a really great job starting the year strongly and we've seen good performance. Peter, why don't I turn it over to you to talk a bit more about what we expect to see in those dynamics for Q1, recognizing that we've not and will not be guidance, but I think certainly Peter can talk about some of those dynamics in more detail. Speaker 200:33:09Peter? Speaker 400:33:11Yes, happy to, Eric. Yes, as I mentioned earlier, I think the across the three core fundamentals of launching a product, I think we made really substantial progress. And in particular, like ASN, I think, really allowed for building that momentum. We saw like an increase of prescriptions, in particular from thought leaders. So we also saw like a good progress in our pulse through in getting patients on base product. Speaker 400:33:36And I think Across the fundamentals, we see that continuation of progress in the 1st 6 weeks of this year as well. I think to your more specific question like What is the insurance reset and reauthorization criteria meaning for the gross to net in the Q1? Well, this is the 1st year we launched So that's going to be a new learning. So we don't know that yet. But if I look at the fundamentals, I'm really pleased with the progress we have been making. Speaker 400:34:07Thanks so much for taking our question. Speaker 200:34:10Thank you. Operator00:34:12And our next question is going to come from Tyler Van Buren from TD Cowen. Please go ahead. Speaker 200:34:20Hey, guys. Good afternoon. Thanks for taking the question. So as part of the sNDA submission by the end of the Q1 for the full approval for Does that include a request to have the black box and REMS warning removed? And if so, can you describe to us how you supported that request? Speaker 200:34:40Thanks so much for the questions, Tyler. Jewel, why don't I first turn to you to talk about the data that we've seen from a safety standpoint. And then, Bill, certainly you can add what we're thinking in terms of engagement with FDA during the sNDA process. Speaker 300:34:57Thanks. So I want to highlight that across our development program and 1st year of commercial launch, including patients who we've had in some of our trials on treatment for up to 10 years, we have had full cases Now I do want to note that there isn't historical precedent removal of the Bill, do you want to comment further on our process? Speaker 600:35:30Yes. With the anniversary of the approval, we will be submitting our 1st annual REMS update, which will highlight the data that we've collected around liver safety and we'll also be submitting the sNDA this quarter, which will give the full 2 year data in the PROTECT study. Both of those give us a launching point to begin the dialogue around a potential modification of the REMS program. At the end of the day, we need to start this dialogue. We don't know what the FDA's response will be, but it's really important for us to have the data that we have now and to begin the conversation and these interactions with the agency. Operator00:36:25Okay. And our next question will come from Carter Goode from Barclays. Please go ahead. Speaker 700:36:31Good afternoon. Thanks for taking the question and congrats on the pickup in sales. A lot of mentions of momentum and reflection on the call there. The new start form increase was somewhat more modest. I guess I'm trying to understand, Is that sort of mid single digit increase in new start farms probably a fair characterization of what we should expect going forward until those inflection points that Peter mentioned sort of hit because it does seem like those are back end weighted. Speaker 700:37:02Any color or commentary would be appreciated. Thank you. Speaker 200:37:06Carter, thanks so much for the question. I'd say that Peter can speak to Some of the qualitative and directional approach that we expect to see throughout the year for both patient start forms and demand, We will not be providing guidance on those for the year, but we certainly do expect to see a strong year of our performance, particularly in revenue. But Peter, why don't you talk in a bit more detail about what we can expect to see moving forward? Speaker 400:37:38Yes. Thanks, Carter, for that question. I think it's the characterization that you have You have to take it into context of a prescriber base that had very little innovation in the last 30 to 40 years. And So I think the adaptation, it takes time to educate the broad community and get to the prescriber base. And within that context, I think the growth that we are showing in Q4 and basically in every quarter in the 1st year, and I think what I called out earlier is that this is the first Recent revenue for our G and A, you see that continual growth. Speaker 400:38:14I think that is something that with the data we expect this year, the guidelines to be updated that there is a good momentum to show continuation of growth in patient start forms and more importantly, ultimately in revenue as well. So I think I understand your question, but yes, I think you have to take it into consideration with an audience that is maybe not used to that much innovation and really requires Like the education, with the experience that they're gaining, and that's what we are seeing right now, is the best advocate for further use and further prescription. And That's where we are right now. So I think in the 1st year of plans to have the continued growth that we saw, I'm really pleased with. Speaker 700:38:53Very helpful. Thank you. Operator00:38:57Our next caller is going to be Murray Raycroft from Jefferies. Please go ahead. Speaker 200:39:04Hi, congrats on the progress and thanks for taking my question. For the EU, you initially had filed for conditional approval and It sounds like that's what you're expecting this quarter, but then you submitted the 2 year data to the EU, which led to the clock stop. So is it possible you could get full approval in the EU? I guess is there any possibility for that or will it still be conditional? And has EMA provided any feedback after reviewing your 2 year data? Speaker 200:39:34Maury, thanks so much for the question. Bill, I will pass that over to you. Speaker 600:39:39Sure. Well, we remain optimistic about the positive CHMP decision that will be made this Q1. The 2 year data I think was helpful for the EMA in making their decision because it essentially removes the regulatory risk associated with their equivalent of accelerated approval. There wasn't discussion of potential full approval And there are aspects of the data package that they don't have yet. The full tables, figures and listings weren't provided more of a top line, look at the 2 year data. Speaker 600:40:17So I wouldn't expect a full approval with this round. Speaker 200:40:24Got it. And has EMA provided any feedback after seeing the 2 year data that they've seen? Speaker 600:40:31No, there wasn't an opportunity in the process for feedback from that. At this point in time, I'm sure we'll have dialogue as we go toward full approval. Speaker 200:40:45Got it. Okay. Thanks for taking my questions. Speaker 400:40:48Certainly. Thank you. Operator00:40:51Our next Person is going to be Tim Lugo from William Blair. Please go ahead. Speaker 500:40:57Hey, Ki Bin, this is John on for Kim. Thanks so much for taking our question. So just wondering if you have any sense on if the agency might require an AdCom to discuss conversion to full approval. And as a follow-up, if you have any sense on the last date that you might be informed that an income might be required? Speaker 200:41:17John, thanks for the questions. Bill, I'll pass that back to you. Speaker 600:41:21Sure. I don't think that this is the type of regulatory decision where the agency would seek advice from an advisory committee. I think the data is quite clear. So there isn't a need to go out to additional external to help interpret trial results. And I think also, there isn't a controversial aspect to this. Speaker 600:41:46So I don't anticipate that the agency will panel an advisory committee. Certainly, if they do, we will be ready. The second part of your question was the timing. Generally, the agency will let sponsors know within 60 days of submission, whether or not they're going to have an AdCom or not. So if we submit in the Q1 by mid to late 2nd quarter, we will know whether or not we're going to be going for an adcom. Speaker 400:42:20Very helpful. Thanks. Certainly. Operator00:42:25And our next question is going to come from Liisa Bayko from Evercore ISI. Please go ahead. Hi. Thanks for taking the question. Speaker 300:42:34Do you have any more color on when the new guidelines We'll be released. Speaker 400:42:43Do what? Speaker 300:42:46We know they're working on it now, but can't provide more color other than we were anticipating potentially this quarter and that means they would be finalized later in the year, but we know it's in the works. Okay. You mentioned compliance rates were good. And can you speak to kind of where you are with compliance? And then Also, can you describe growth to net for the year? Speaker 300:43:12Like what kind of average for the year you be thinking about or what would normalize, any color there would be helpful? Speaker 200:43:21Sure. Peter, I'll turn that over to you. Speaker 400:43:27I'll take the question on the compliance and Chris maybe you could take the gross to net then. So on the compliance rate, Like if you look at Bensmore for chronic disease without a non symptomatic disease, overall compliance rates are Not very high. What we see with Fiospari so far, it is actually really high. It's higher than what we anticipated, especially when you also program with like monitoring that requires monthly liver testing. So, so far, we see very strong compliance rates. Speaker 400:43:59I it speaks also to the experience patients are having, and that's for the first time they actually see that they're being controlled to the target levels. And I think you have to take into consideration, like a lot of those patients, they feel that they're losing. I mean, over the course of their disease, they hear every time from their physician that They're not yet on the target. And I think now with Stealthari, they feel like, hey, you know what, we are able to reach the target. And I think that is motivating patients to continue to use the product. Speaker 400:44:25And that's why I think we see also high compliance rates. Speaker 600:44:31And Lisa, just on the gross Speaker 500:44:32to nets, We've been pleased with how we've seen things meet our expectations of having a mid to high teens growth in that. The only thing that I would say is for 1Q with reset of the year, we may see that be a little bit higher as we have some of our other products in the past. But overall for the year, we would expect it to remain in that mid to high teens level. Speaker 300:44:52Okay. And then can you comment at all on like how many patients were on kind of exiting 2023 on VOSPARI? Speaker 200:45:04So we've not provided guidance for any KPIs on number of treated patients. I think Peter can talk about directionally what we were seeing as we ended the year. But Lisa, we're going to continue to provide updates on PFS, on payer coverage and on revenue at this point in the launch. Peter, you want to provide anything further towards this question? Speaker 400:45:33I think that's right, Eric. As I mentioned earlier, I think we're making robust progress on all the fundamentals, including the pull through getting patients on base product. I think the process is well within benchmarks, you would expect from rare disease products. And so I think we will see that continuation and it will be reflected by revenue as well to Iris' point. Okay. Speaker 400:45:57Thanks. Thanks, Lisa. Operator00:45:58Our next question is going to come from Pramil Divan from Guggenheim. Please go ahead. Speaker 900:46:05Great. Thanks for taking my question. Maybe just a couple of follow ups on the payer side. So I think, Peter, I think you mentioned in your Prepared remarks that the payers are they're sort of acting generally consistent with the label in terms of the patients that they're reimbursing therapy for. I'm curious if maybe you can just give a little more detail there in terms of when they're deviating from the label, sort of what issues, if any, are they sort of raising? Speaker 900:46:31And then the second question I have is more around the full approval, assuming you get that sort of later in this year. Would you expect sort of immediate change in sort of payer behavior on that? Or is that something we probably have to wait until So the 2024, 2025 cycle starts up in terms of formulary status or authorizations. Speaker 200:46:55All right. Peter, I'll hand this over to you. Speaker 400:46:59Yes, very good. With regards To authorization criteria, I mean, there's always certain aspects that the payer is expecting to see. And so I think where we are is that, Especially in the beginning when we got the label and the label was kind of fake on patients with rapid progression of disease with regards to proteinuria states like generally 1.5. When we are seeing that payers in most of the authorization criteria refer to the label, but Also refer to the clinical guidelines, and that has lower proteinuria targets, so that allows for a broader use. And that's why to my earlier point in the call, With a further lowering of the proteinuria targets within the Codigo lines, accompanied with like a broad label for filsparin And this allowed them also for a broader patient population that is eligible for paid products. Speaker 200:47:52And then Peter, what is your comment on the question around full approval and how payers will respond full approval on how quickly they might be able to review? Speaker 400:48:04Yes. So I think it speaks a little bit to what I said. There's a further lowering of proteinuria targets and then Also a broader label where there is no restriction in proteinuria, that authorization criteria on a threshold of proteinuria may disappear, and so that allows for a broader patient population. I think that's one aspect. I think another aspect is, and I think your question may have been Referring to like the evolving competitive landscape as well with new competition coming in, I think the lead times that we have and the strong base that we have in formulas provides a very strong position, especially since we have like the highest standards for study design. Speaker 400:48:44I mean, this is the only study that has competitive competitor, which is basically the gold standard, how a payer is evaluating new product. I think we are in a strong position with regards to lead time as well as study design and how payers are evaluating that in the evolving landscape. Speaker 900:49:07Okay. Thank you. Operator00:49:10And our next question is going to come from Alex Thompson from Stifel. Please go ahead. Speaker 1000:49:16Yes, great. Thanks for taking my question. I want to Maybe could you talk a little bit about the HARMONY study through your expectations around enrolling 70 patients or at least up Based on your experience with the Phase onetwo, how well identified are these patients? If this is a 12 week primary endpoint, Top line, is the 2026 readout conservative at this point? Or how are you thinking about that? Speaker 1000:49:43Thanks. Speaker 200:49:45Alex, thanks so much for the question and also for the focus on the pegmatinase program. Jula, I'll turn that one over to you. Speaker 300:49:54So thanks. We think this is an exciting trial design that focuses on changes in total hemophilia, not just at 6 to 12 weeks, but also looking at durability of effect. So it is a 24 week study and then patients roll over to our open label, which is able to look at diet liberalization. And to your point, we are looking to recruit 70 patients from more sites than we did from COMPOSE. It's about 50 sites overall, which will give us top line data in 2026. Speaker 300:50:21And while we have started the trial and we do have a list of patients who are excited to participate, We are intentionally moderating our enrollment initially to ensure we have a good experience for the sites and patients and also proper training at some of these sites who some of which are research naive and then also to ensure our CMC scale up to support the full study as well as commercialization. Speaker 200:50:45So I think perhaps if you can comment on the enrollment period before for screening that it helps explain why the timeline may be a bit longer than what people would typically say for this type of trial. Speaker 300:51:02Yes, thanks. So because it is a 6 month trial, plus we have a 10 week run-in period where patients get screened to make sure they qualify as well as standardize their diet and that's really to try and optimize our chance of success that patients have understand the trial that they need to keep their diet table, which clearly is going to impact your endpoint. We want to maximize our chance for success at the end. So it's a bit longer than what you first stated? Speaker 200:51:30Yes. And we'll certainly look to move swiftly on this, but we for all of the reasons that you'll have explained, We've been very thoughtful around the timelines that we've put out there. Alex, the only other thing that I would mention that we that gives us confidence in the enrollment is that as we see increased awareness within this community, There are more and more patients that are being identified and we would absolutely expect that there will be a growth in the number of patients identified diagnosed in the overall market growth. So this is something that we believe will certainly be a tailwind for us with the HARMONY trial and even more so as we look to reach these patients once we have approval. Speaker 1000:52:17And I guess, How many patients do you feel like you need to enroll to feel confident in powering if it's not 70? Speaker 200:52:27Bill, why don't you talk about the powering? But I can say we absolutely are confident in finding these patients. I think we've been able to help in thinking through where these patients are, which sites, etcetera. So I think, JUULA's team has done a really great job of ensuring how we can enable success in the HARMONY trial. So I think Bill you can talk about a high level of the powering. Speaker 600:52:50Yes. No, certainly, and I appreciate the question. We're very confident in the powering of the study and recall in Julia's initial remarks, she mentioned the 67% reduction in total homocysteine that was observed in Phase II. So with that level of efficacy, even with a significant diminution in the treatment effect or a reduction in the overall total sample size, which we don't anticipate, we certainly are in a good place to still achieve the endpoint. So, I'm confident that we'll get there. Speaker 500:53:46Jenny, can we move to the next question please? Operator00:53:52Yes. We have Mohit Bansal. Can you hear me? Speaker 200:53:56Yes, I can. Yes, we now can. Operator00:53:58Okay. Speaker 1100:54:03So I did not hear you at that point. Sorry about that. Thank you very much for taking my question and congrats on the progress. Just wanted to understand, I mean, I know you don't provide the patient count, but if I look at the average number of patient forms, I mean, from Q2 to Q3 and then quarter to Q4, it seems like there's a 57% increase, but then there's a substantial increase in revenue. So Is this because you are converting a lot more of those patients form into paid patients Or is there a stocking part involved here? Speaker 1100:54:40Can you help us understand that? And then last second question is On the price increase, I think you took a price increase in January. Should we expect some benefit in 2024 due to that price increase? Thank you. Speaker 200:54:53Okay. Thanks so much for the question. Peter, I will turn that over to Speaker 400:54:57you. Yes. So, thank you, Mohit, for that question. So, as I mentioned, like one of the core fundamental is making sure that patient starts from transition ultimately to patients' own products and in particular patients' own paid products, so you continue to increase the revenue. And I think what you saw in this quarter is that we made robust progress, In particular, also on the pocket of patients that we described in the earlier quarter, which that required some additional handholding and education with As I mentioned, like the patient REMS certification was in the 1st 14 days has increased quite substantially, and that allowed patients to go through the process and get to base product more quickly. Speaker 400:55:47So Good progress there. To Erik's earlier point, we don't provide further details on how many patients we have on product, but I think The transition from patients' platform to ultimately a patients' paid product, we made significant progress. On the second question with regard price and price increase, indeed, we had a price increase in the beginning of the year. Now that we have the confirmatory data and you see that the proteinuria Reduction, the robust pottery reduction provides longer term eGFR and kitten preservation as well. So we thought it was justified to have a price increase for this year. Speaker 600:56:28Got it. Speaker 200:56:29And maybe just one final thing, Mohit, for your question on inventory, that has been stable. So there has been no pattern of stocking. So I think Peter is absolutely right. We expected to see a greater inflection in revenue as our teams are able to help those patients through the process. You would imagine that that is going to continue that trend this year with faster growth in revenues than perhaps what we see in patient start forms, but we'll certainly apprise you how we're doing at the Speaker 400:57:00end of Q1. Thank you. Operator00:57:06And our next question is going to come from Yigal Zhokomovitz from Citi. Please go ahead. Speaker 1200:57:17Hi, Travir team. Thank you very much for taking the questions. I had one on FSGS. Just curious if there were any recent updates With regard to the work that I believe the FDA is doing in collaboration with you on defining some of the optimal endpoints For FSGS, whether there's some variations of the EGFR slope endpoint that may be more appropriate based on some of the data cuts that you're exploring? And then secondly, on the broader landscape in IGAN, just wondering, obviously, there's been a lot of visibility around some of the newer mechanisms, anti B cell mechanisms. Speaker 1200:57:50Wondering whether Filspari, given its position as a foundational therapy, may benefit from a combo study using the B cell modulators on top of ZOSPARI at a future point? Thank you. Speaker 200:58:05Great. Thank you for the questions. And July, we'll turn those over to you. Speaker 300:58:11Thanks. As far as FSGS, we are continuing to do our analysis with our data and then external data sets our trial data into historical context. With regards to the FDA, this is a partnership with NEFCure, which is a patient organization with academics and the FDA and it's called Parasol. There's a website, it's public. And it's really to redefine the endpoints. Speaker 300:58:34And What they've recently announced is they're really looking at alternative proteinuria based endpoints to help enable the regulatory pathway for SGS. We plan to reengage the FDA following their final analysis and decision on what those endpoints should be under this Parasol group, and they're targeting ASN for that timeline. And then your second question is around some of the newer agents and how should be placed. And I think it's really going to be an exciting few years for IgA nephropathy patients with some of these new therapies, most of which target different parts of the injury cascade contributing to IgAN and hopefully they'll become available outside the context of a clinical trial, but we're a few years away from that. But I would add that all additional immune modulating agents are being used on top of standard of care foundational treatment. Speaker 300:59:26And that's where so Safari plays a foundational role because it targets the injury in the kidney and the response to the GDIGA deposition and protects against further damage. And really, we're really aligned with the KOLs. You need to target 2 things, the ongoing damage in the kidney with foundational treatment. And to your point, you could potentially add another agent that targets upstream pathways, that's additive. As far as other trials, I think it's important to realize that every other trial is studying a new agent on top a standard of care. Speaker 301:00:01And many of those trials now because of Sillsbury superiority over ACEs and ARBs, They're being allowed as part of the foundational standard of care. So we will get data over time from these trials as they read out about the combination and then being used together. Speaker 201:00:20And we certainly are interested That combination and generating additional data, I'm very proud of Jules' team, where we do have 2 ongoing studies looking at the combination of Vilspari plus SGLT2. I think some of the few combination studies that have yet been initiated, we would expect that that could potentially increase as other therapies are actually approved. Speaker 1201:00:45Great. Thank you very much. Operator01:00:48And our next question is going to come from Ed Arce from H. C. Wainwright, please go ahead. Speaker 1301:00:55Hello, everyone. Thanks for Congrats on another quarter of progress. A couple of quick questions for me. Firstly, with With regards to the sNDA later this quarter for FASPARI for approval, Just wondering if you could confirm the length of the review period that you would expect 6 or 8 months or would that roll into some next year. And then secondly, as I look at the PSF Quarter over quarter so far in last year, and as those growth rates moderate a bit, I'm wondering if you can discuss Some of the 2 inflection points that have been mentioned before later this year, the Codigo guidelines and the upcoming data analysis from ongoing trials, especially the SGLT2 combo. Speaker 1301:01:54What impact and I Speaker 401:01:57guess this Speaker 1301:01:57is a question more for Peter, but what sort of subjectively What impact would you expect those to have on treating physicians as they get more experience with the drug. Thanks. Speaker 201:02:15And thanks for the questions. Bill, why don't you take the regulatory And then Peter, you can take the PSF outlook question. Speaker 601:02:26Yes. We expect to have priority review Out of, for this, SNDA that would be consistent with how the agency treated a predecessor that went just recently before us. In that case, it would be a 6 month review. So you'd have a Q3 decision. If we were standard review, it would take to the end of the year. Speaker 601:02:50So in either case, we have a decision this year. I'll Pass over to Peter for the rest of your question. Speaker 401:03:01Yes. Thanks for that question. I think there's really two elements that I would like To point you to, with regards to the evolving landscape, with regards to the guidelines as well as a broader label and what would that mean for the potential for patient start forms in the future. I think there's 2 core elements. 1 is the urgency to treat or better the urgency to change. Speaker 401:03:26With further emphasis, you have to go lower. Protonuria at the level of lung is still not where you need to be. And I think last year, the radar data got published from the U. K. It's registry data, and it shows that even with a proteinuria of 0.9, those patients actually have doubled the progress to end stage kidney disease compared to patients that have an opportunity level of in average of 0.44. Speaker 401:03:51So I think these kind of data and then reinforcement in the guidelines further amplifies the urgency to change for those positions and change that foundation that is currently ASMRs and replaced it with a much more efficacious treatment like Filspari. And just to recall, I mean, the proteinuria benefit that Filspari had after 9 months was 3 fold, 15 versus 15. But after 2 years, it was actually 10 fold. So I think that is an important aspect. So the urgency to change, I think, is one aspect. Speaker 401:04:26The second one is really it allows for a broader patient population. And What we have highlighted earlier is that we said at launch, we expect to have an addressable patient population for Filspari between 3,050,000. We think with the broadening of the label as well as further highlight of the KANU guidelines to go to a lower proteinuria target, we think there is up to 70,000 addressable patients fulfill sparing. So I think those are the 2 core aspects I would want to highlight with regards to the evolving landscape and what it means for the addressable patient population and potentially patient starts for TOSFARI. Speaker 201:05:03Thank you, Peter. Julia, is there anything that you'd like to add? Speaker 301:05:06Yes, thanks. I think it's we have a couple of inflection points and Peter nicely highlighted CAGIGO to treat patients earlier and diagnose them earlier. And then the SGLT2 combination, we know that combination therapy is going to be important So we think those are 2 things. But the third thing that I want to point out is with regards to the earlier treatment. We have a trial called Spartan where we utilize early after they first get diagnosed and they're RAS naive. Speaker 301:05:33We presented some of that data at ASN and it shows Earlier, we've seen 80% reduction in proteinuria. Most of the patients getting into complete remission and no change in eGFR over 36 That trial has been continuing. We'll have additional data on that over the years. But, I think that's an additional point as far as treating patients earlier in their disease course. Speaker 201:05:56Yes. Thank you, Peter and Julien. Maybe if we just take a step back for a moment, if we put ourselves towards the end of 2024 And you assume that we have a full approval with a potential broader label just as the Codigo guidelines potentially lower the target and really increase the dynamism in the treatment of patients with IgA nephropathy, We really will be at the right place at the right time. And if you think about also all of the clinical experience that physicians are getting with VILSPARRI. There's one thing that we know from this launch and hearing from physicians and their patients who are on PILspari. Speaker 201:06:40It is a very rapid and consistent reduction in proteinuria. We believe that we'll be in the right place at the right time. And I think our goal is to make sure that we continue to expand for new physicians to be able to get that clinical experience. And we believe that positions us very strongly for future growth. Speaker 1301:07:01Great. Thank you so much. That's very helpful. Operator01:07:05And our next question is going to come from Laura Chico from Wedbush Securities. Please go ahead. Speaker 1401:07:11Hey guys, thanks very much for taking the question. I'd like to shift gears and ask one on pegdevatinase. And Eric, your comments there about kind of the phenomena we see with orphan disease and the expansion of patient populations over time. I apologize if I missed this, but do you plan to keep a patient registry with respect to HCU? And Kind of related to that, would you be able to disclose an identified patient number as you're going along? Speaker 1401:07:38Thank you. Speaker 201:07:41Great questions, Laura. Yes, we do have a registry and we do continue we plan to continue that. We think that that's an incredibly important source of information for the community. And it's really a great question around sharing patient information or identification. That's certainly something we know others have done. Speaker 201:08:01We'll be looking at the potential for us to be able to do that as well. Can't commit to it today, but absolutely something that our team is looking at.

With that, let me now turn the call over to Eric. Eric? Speaker 200:01:42Thank you, Anne, and welcome, everyone. 2023 was a year of many great achievements for Travir as we worked towards our goal of breaking down barriers and treating rare diseases with historically little innovation. At the start of 2023, we gained the 1st approval from our pipeline delivering sparsentan or silspari as the first and only non immunosuppressive treatment option for people living with IgA nephropathy or IgAN. For decades, people living with IgAN, most of whom are diagnosed in their 20s 30s and on average face kidney failure in 10 years and limited treatment options. We are proud to help lead the growing evolution of the treatment paradigm that we believe will ultimately see patients get diagnosed and initiate treatment earlier and where physicians will ultimately utilize SPILsparri as a foundational treatment with its superior proteinuria reduction and accrual of kidney preservation benefit. Speaker 200:02:38Following the grant of accelerated approval, Our team quickly initiated our comprehensive commercial launch plan and worked throughout the year to lay a strong foundation for a PULSARRI uptake. I am very pleased with our results. We continue to make substantial progress in physician demand, payer coverage and revenue, the key aspects of the launch. Of note, VILspari is the only recent launch in the rare kidney space that has seen consistent growth in demand each quarter in its 1st year. And we saw a meaningful inflection in net product sales to close out 2023. Speaker 200:03:13Last year, we encountered a challenge in our pursuit of a better outlook for the FSGS community. Specifically, the DUPLEX study of sparsentan in FSGS did not achieve the results we had hoped. And following our FDA engagement, it was clear we would not be in a position to submit an sNDA at that time based on the DUPLEX results alone. I'm incredibly grateful and proud of how our colleagues at Trevir learned and quickly adjusted. We moved quickly to align our investment in this program, implement a strategic restructuring of our organization to focus our resources and concentrate our efforts to collaborate with regulators with the goal of identifying regulatory path forward in the future. Speaker 200:03:56As for pegmatinase development program for classical homocystinuria or HCU, We achieved important milestones in 2023. Globally, we believe there are 7000 to 10000 patients diagnosed with HCU who are not in full control of their homocysteine levels. With better diagnoses and a future where an effective treatment is available, we believe this may grow by 50% or more over time. Last year, we generated additional exciting data from our Phase to COMPOSE study, which further demonstrates the potential for pegdubatinib to become the only disease modifying therapy for HCU. With these data, we worked closely with regulators to align on a Phase 3 program, utilizing total homocysteine reduction as a primary endpoint and initiated that study before year end. Speaker 200:04:45All of our efforts last year positioned us to start 2024 with focus and a plan for execution across the board. Strong launch performance in Valspari remains our top priority for 2024 And we expect the momentum in our launch from the second half of twenty twenty three will continue into the New Year. We are also executing on 3 additional priorities aimed at broadening access to Vilspari. Of note, we are on track to submit our sNDA this quarter to support version of Vilspari from accelerated approval to full approval for IGAN in the U. S. Speaker 200:05:19Together with our partner CSLV4, We expect an opinion on conditional approval of Vilspari in Europe from CHMP later this quarter. We're optimistic that this will be positive. And with our recent agreement with Rinalis, we are looking forward to aiding their development plans to ultimately enable access to VOSPARI in Japan and other regions in Asia, where IgAN is an even more prevalent disease and leading cause of kidney failure. And importantly, we are excited about the opportunity we have with pigdevatinase, our novel investigational enzyme replacement therapy being evaluated for the treatment of classical homocystinuria or HCU. In 2024, our focus will be on enrolling our Phase III HARMONY trial and raising awareness of the need for innovative treatments for this rare disorder. Speaker 200:06:07Let me now turn the call over to Jula for a clinical update. Jula? Speaker 300:06:11Thank you, Eric, and good afternoon. I am very pleased with the progress made on our clinical and medical affairs initiatives in 2023. With our achievements last year, we are well positioned to ultimately deliver 2 new treatment standards in rare diseases with limited options available. At Borfil Spari, we completed the 2 year double blind dosing periods for our studies in FSGS and IgAN. It's important to highlight that our studies are the only ones in the space that use a maximally optimized active comparator, setting the bar highest in the field. Speaker 300:06:48The results, which clearly demonstrated robust proteinuria reduction and preservation of kidney function in IgAN were simultaneously presented as late breaker presentations at ASN and published in world renowned medical journals, The Lancet and New England Journal of Medicine. Following those data presentations, we have received positive feedback from nephrologists about the foundational role that ZILFARI can play in long term kidney function preservation for patients with IgA nephropathy. What has resonated with nephrologists is that ZILFARI is the only approved non immunosuppressive treatment for IgAN and it's the only molecule that works by simultaneously blocking the 2 key pathogenic pathways in the kidney, endothelin 1 and angiotensin 2 that both work together to drive damage and kidney function loss. ZILFARI's dual mechanism of action is critical to inhibiting the damaging pathways in the kidney in order to achieve sustained proteinuria reduction and long term kidney function preservation that accrues over time. Unlike intermittent therapies, which may have short term benefits on kidney function, ZILFARI demonstrated a long term accrual of benefit on eGFR. Speaker 300:08:06In the PROTECT study, at 1 year, there was a 1.7 ml per minute Favorable effect on absolute eGFR with VILSPARI compared to maximally titrated erbasartan. And that benefit increased to 3.7 ml per minute greater eGFR at 2 years. Importantly, The rate of loss of kidney function in year 2 compared to year 1 was significantly slower for Vilspari treated patients, suggesting a potential additive benefit with longer term treatment. This year over year accrual of benefit is important for a patient who has ongoing kidney injury over their lifetime and may otherwise be facing kidney failure less than 10 years from diagnosis. Our 2 year data from the PROTECT study in IVAN shows that Sulfari is superior to historical RAF inhibitors and it's safe for chronic use, which is critical in treating patients for life. Speaker 300:09:07Community and academic nephrologists are continuously highlighting to us the Early clinical experience with ZILSPARI, where they see significant reductions in proteinuria and the ability to safely use FILFARI with our patients chronically. We believe this cements the role that FILFARI can play by replacing RAS inhibitors as foundational care for those at risk of rapid disease progression due to uncontrolled proteinuria. Following the positive results from PROTECT, We successfully completed a pre NDA meeting with FDA to discuss our plans to submit an sNDA to convert Filspari from accelerated approval to full approval for IgAN. Importantly, we aligned with the FDA on the data analysis to support our submission and to support potential broader labeling. I'm pleased to report that we remain on track to submit the sNDA this quarter. Speaker 300:10:01We are at an exciting juncture in the evolution of the IgAN treatment paradigm. We believe that nephrologists are focused on treating the damage in the kidney and then preventing further damage systemically. Our goal is to ultimately have VILFARI used as the foundational care in IgAN, essentially replacing the historical role of RAS inhibitors and then other medicines can be added as needed. As this evolution continues, there are a number of factors that we expect will help Vilspari achieve this goal. With a full approval from FDA, we would expect a broader label that reflects the full study population and the results. Speaker 300:10:39This would provide nephrologists and patients with greater flexibility to choose Vilspari when seeking treatment options that can provide long term kidney function preservation. Additionally, we believe Vilspari's likely inclusion in the soon to be released KDIGO guidelines should further standardize use of Vilspari for the nephrology community and potentially result in earlier treatment. As positioned in up to date and recent peer reviewed IGAN treatment article, We anticipate Vilspari will be described as a foundational treatment in the KDIGO guidelines. We also believe that the proteinuria target for treating IgANT overall will be lowered, which would support earlier diagnosis, more aggressive treatment to avoid long term damage as well as combination treatment in the future. Furthermore, later this year, we expect to generate longer term data from our ongoing Spartacus and SPARTAN studies, which are designed to show Filspari can be safely used in combination with other medicines such as SGLT2 inhibitors and that patients may benefit from earlier use of Filspari. Speaker 300:11:46Such data will further support the progress towards Filspari achieving foundational care. Beyond the U. S, we have continued to work closely with our partners at CSL Vifor on the conditional marketing authorization application that is currently under evaluation in the EU. Following a procedural clock stop to review the 2 year data, we believe that we are well positioned for a positive CHMP opinion this quarter and an approval decision next quarter. Beyond the CSLV4 territories, our recent agreement with Renalis provides Filspari with a regulatory pathway that has the potential to deliver Filspari across a number of Asian countries in the coming years. Speaker 300:12:28Overall, we are very pleased with the important groundwork laid in 2023 and we see a clear roadmap for increased utilization of DYOSPARI for IGAN in 2024 and beyond. Turning briefly to FSGS. With no approved therapies for tens of thousands of patients with this condition and the high rate of progression to kidney failure, we are committed to trying to find a path forward for sparsentan and FSGS. We are taking a measured approach to evaluating our data sets and working with the community to re engage the FDA later this year Toward the goal of ultimately being able to submit to have an FSGS indication added to the Filsparin label, we anticipate being able to provide an update on this work late in the As Eric highlighted earlier, our enthusiasm in pegtobatinase continues to grow. We were pleased to achieve alignment with regulators on the design of our Phase 3 program and to reach our goal of initiating the Phase 3 HARMONY study before year end. Speaker 300:13:30This study employs an innovative design with measurements very similar to our highly successful Phase III study, which we believe provides a high probability of success as a registration enabling study. The Phase III HARMONY study is designed up to 70 patients with HCU and evaluate change in total homocysteine from baseline to week 6 to 12 as the primary endpoint. This is the measurement for which we saw a 67% reduction in the highest dose cohort in the COMPOSETI. Patients will be followed in the double blind period for 24 weeks in total to establish durability of effect and a robust safety database. To maximize consistency, there is a 10 week screening and diet stabilization period prior to randomization in Harmony. Speaker 300:14:20And patients who complete the full double blind period will be eligible to enroll into an open label study called ENSEMBLE, where there is a protocolized diet liberalization substudy for eligible patients who have well controlled total homocysteine. This portion of the study is designed to generate data throughout the life of the program and we believe it will ultimately be able to help patients understand Avant may be able to increase protein intake while taking pegtobatinase, a key area of need for patients living with HCU. As we move through 2024, we will be focused on ramping up enrollment in the HARMONY study and scaling our pegtubatinase manufacturing activities to support the full program and future commercialization. We look forward to top line data in 2026 with the potential approval in 2027. I'll now turn the call over to Peter for the commercial update. Speaker 300:15:13Peter? Speaker 400:15:15Thank you, Lat. Looking back on 2023, We made robust progress on what we have outlined during our launch call in February last year. Precision feels powering iGAM as the future foundational care for patients at risk of rapid progression through educating our nephrology targets, securing broad access and ensuring a positive initial sales by experience for patients and physicians. And I'm really proud on the progress our commercial team has made in the past year, especially while adapting to the initial promotional restrictions that come with accelerated approval and an unexpected advanced program for liver monitoring. By the end of 2023, we reached 5,700 nephrologists with our sales team in regular face to face educational interactions. Speaker 400:16:03That is 95% of our target base of 6,000 nephrologists that we believe treat about 85% of the addressable IgM patients in the U. S. These efforts resulted in strong and steadily increasing demand with increasing breadth and depth of prescribing nephrologists. In particular, in the Q4, we built strong momentum to fulfill spa in demand, And I couldn't be more pleased with how we ended the year. It was encouraging to see further growth in new patient start forms or PSFs after ASN Kidney Week, where the confirmatory PROTECT study results were presented and published. Speaker 400:16:44Importantly, we also received further validation of the Valsari profile from card leaders, which was evidenced by an increase in key opinion leader prescribers. We ended the 4th quarter with 459 new PFS, which demonstrated quarter over quarter growth for each period in 2023. In fact, this is the first recent rare nephrology product has shown a continuation of growth in demand during each period of the first in the 1st year of launch. In total, we received more than 1450 patient start forms in 2023, which clearly indicates TILSTARI is helping fill a significant need for the nephrology community. On the payer front, We established a strong base allowing broad patient access. Speaker 400:17:33By the end of the year, coverage reached about 70% of U. S. Lives. In the Q4, we added about 180 new FilSpari specific formularies. And overall, More than 1,000 formularies have included Schilzpari with authorization criteria that are generally consistent to the Schilzpari label. Speaker 400:17:54And if we account for plans that didn't yet include Fiospari, but have a clear pathway for coverage, that total is about 89% of U. S. Lives. Following our teams quick adjustments to improve Patient education provides further support for the liver monitoring REMS in the second half of the year. We saw continued progress in our lead measures of REMS certifications in the 1st 14 days after receiving patient start form. Speaker 400:18:24This also led to a growing number of reimbursed patients initiating therapy during the quarter. And we are hearing almost on a daily basis from patients and physicians How impressed they are with the results that they have shared with Celsparium. These results are consistent to what was observed in the PROPECT trial, with rapid and sustained proteinuria reductions with a safety profile similar to ACE inhibitors and ARBs. This is encouraging for patients that started using VILSTARI and likely why we are seeing high compliance rates so far in the lungs. All these accomplishments resulted in a significant increase in net sales party sales. Speaker 400:19:08In the Q4, we reported approximately $15,000,000 in net product sales, which resulted in nearly $30,000,000 for the year. IOLA and IOLA DC also remained steady, contributing approximately $25,000,000 in net product sales in the Q4. We recently learned of an approval of a generic Thiola we see with a narrower label, and we will continue to monitor what impact that may have throughout the year. Overall, we ended 2023 with solid execution, And this provides us with a robust foundation for strong performance in 2024. In fact, in the 1st 6 weeks of the New Year, I'm pleased to see our strong filsparity performance continue. Speaker 400:19:51Our team is ready to show the true potential of filsparity in this new year, And we have multiple inflection points throughout 2024 that provides confidence in continuing growth. Let me highlight the 4 areas that I am particularly excited about in the coming year. 1st, if we achieve full approval as targeted for later this year, We anticipate that an updated and potentially broad label would provide greater support for physicians to prescribe TOSPARI to more of their patients. 2nd, as Jula mentioned earlier, we anticipate that Zolpi will be included in the global PDU guidelines scheduled to be updated this year. This will potentially provide uniform guidance of physicians to choose GLStARRI as an early treatment for their patients. Speaker 400:20:393rd, additionally, if the guideline revision emphasizes earlier intervention by lowering the proteinuria target, It would likely amplify the urgency to diagnose and treat patients earlier. We believe this would increase the number of patients that would be eligible for Filspari. And importantly, a broader label together with a potentially lower target to treat earlier in the guidelines would allow us establish ZOSFARI as the foundational treatment in a larger addressable patient population. And 4th, We expect the additional clinical evidence Ziola highlighted earlier will ultimately provide additional support for physicians to treat earlier RASIL STARI and use it in combination with other available medicines for patients that may need more progressive treatments. With all of this in mind, I could not be more excited about Fiospari's prospects in this new year, and we feel strongly that we are well positioned for significant growth in 2024. Speaker 400:21:40Let me now turn the call over to Chris for the financial update. Chris? Speaker 500:21:46Thank you, Peter, and good afternoon, everyone. Following our Q4 results, we're in a strong financial position. From an operational perspective, we continue to grow revenues and we focus our investments on the ongoing launch of ZOSPARI and IgA nephropathy and the advancement of our Phase III effective adenase program. For the Q4 of 2023, net product sales were $39,900,000 compared to $25,800,000 for the same period in 2022. The increase is attributable to growth in net product sales from the ongoing launch of FOSPARI and IgA nephropathy. Speaker 500:22:16During the quarter, we also recognized $5,100,000 of licensing collaboration revenue, which results in $45,100,000 in total revenue reported for the period compared to $29,300,000 in the same period in 2022. Research and development expenses for the Q4 of 2023 were $59,700,000 compared to $58,100,000 for the same period in 2022. The difference is largely attributable to the continued advancement of our pecdevatinase clinical program, partially offset by reduced investment in our Filspari Phase 3 programs following the readouts from the 2 year endpoints. On a non GAAP adjusted basis, R and D were $55,300,000 for the Q4 of 2023 compared to $52,000,000 for the same period in 2022. Selling, general and administrative expenses for the Q4 of 2023 were $63,600,000 compared to $57,100,000 for the same period in 2022. Speaker 500:23:09The difference is largely attributable to the commercial launch related activities following the accelerated approval of VOSPARI in February of 2023. On a non GAAP adjusted basis, SG and A expenses were $49,700,000 for the Q4 of 2023 compared to $44,300,000 the same period in 2022. During the Q4, we recognized $11,400,000 in restructuring fees related to the strategic reorganization that was announced in December. Total charges related to the reorganization are expected to amount to between $12,000,000 $14,000,000 Total other income net for the Q4 of 2023 was $5,700,000 compared to $1,100,000 in the same period in 2022. The difference is largely attributable to an increase in interest income during the period. Speaker 500:23:53Net loss including from discontinued operations for the Q4 of 2023 was $90,200,000 or $1.18 per basic share compared to a net loss of $65,800,000 or $1.03 per basic share for the same period in 2022. On a non GAAP basis, net loss including from discontinued operations for the Q4 of 2023 was $71,800,000 or $0.94 per basic share compared to a net loss of $46,900,000 or $0.73 per basic share for the same period of 2022. As of December 31, 2023, the company had cash, cash equivalents and marketable securities of $566,900,000 Looking ahead, we expect meaningful growth in net product sales of FOSPAR in 2024 and we look to achieve non GAAP operating expenses below $400,000,000 for the year. We also anticipate meeting milestones with both FOSPHARRI and pepetabadenase that will result in us making expected net payments of approximately $50,000,000 during the year. With our strong balance sheet, the expected growth in TILESPARI revenues and measured investments, We currently expect that our cash balance can support operations into 20 28. Speaker 500:24:58I'll now turn the call back over to Eric for his closing comments. Eric? Speaker 200:25:02Thanks, Chris. We are entering a new phase of growth for Travir. Our organization is well positioned with strong financial foundation to continue advancing TILFARI and pegdovatinase as potential futures treatment standards for their respective rare kidney and metabolic disorders. Moreover, these global markets collectively are projected to exceed $10,000,000,000 in the coming years. Our unrelenting drive is based on our desire to deliver life changing therapies to people affected by IgAN, HCU and potentially FSGS, who historically have had little to no innovation for their condition. Speaker 200:25:41We see near term and long term growth through the following: the continued strong execution of our Filspari launch, the expected conditional approval of sparsentan in the EU and full approval of Vilspari for IGAN in the U. S. With potential broader labeling, updated iGain treatment guidelines and further data generation to reach the growing number of patients in need of a better therapy. Finally, I am particularly excited about the advancement of our development program for pigdubatinase as the only potential disease modifying therapy in a market that is to grow meaningfully over time. This year, we look forward to raising awareness of HCU and enrolling the Phase III HARMONY study with a goal of achieving top line data in 2026. Speaker 200:26:30Let me now turn the call over to Anne to open up the lines for Q and A. Anne? Speaker 100:26:36Thank you, Eric. We can now open the line up for Q and A. Jenny? Operator00:26:42Thank We will now take the first question from the line of Joseph Schwartz From Leerink Partners. Please go ahead. Speaker 600:27:11Great. Thanks very much and congrats on all the progress. I guess I'll ask on, Filspari, how much does the higher hurdle that Filspari had in the PROTECT trial seem to resonate with the prescribing community. Do they appreciate that patients in the control arm were so well managed? Does this impress them or do you have more education to do in order for them to appreciate FilSparis relative to performance and protect? Speaker 200:27:41Joe, thanks so much for the question. Peter, why don't I turn that over to you and perhaps you can also comment on what we saw coming out of ASN where there was Much more discussion about the PROTECT trial and trial design. Speaker 400:27:57Yes. Happy to take that question, Joe. I would say the conversations I've had with physicians, and I think that's also being underlined with the market results that we saw. But if we outline the study design of PROTECT And the understanding of like an active control arm is understood. There's really like great appreciation for the for the very robust results that we have. Speaker 400:28:23You highlighted earlier in the call like 1.7 ml per minute per year improvement. And then in the second year, you saw actually 3.7 ml per minute per year. So an accumulation of benefit over time. And I think that is something that the physicians, If they understand, we signed really speak highly of. Speaker 200:28:44Okay, Julien. Okay, Julien. Speaker 400:28:44If you want to comment. Speaker 200:28:47Thank you, Jill. Jill, is there anything that you'd like to comment from your team engagement with thought leaders on that trial design And the high bar? Speaker 300:28:58Yes. I think it does take some education because all the other trials are comparing to a not fully optimized standard of other patients, which we know historically 50% and really all the other trials aren't Yes, we have a higher hurdle. And so when they initially see the comparison in the slope, most of which they don't look at in their clinical practice, It takes some education to look at the benefit and then also the accrual of benefit that we should see. We only did a 2 year snapshot, but you know that If you have a benefit that's better in year 2 versus year 1, then that's going to continue to improve year over year. So it does take some time, but they get it once they spend time with the data and the information. Speaker 200:29:40Yes. And I think this is going to be Joe, a very important part of why we're eager to have full approval and a label that will allow us to talk about that long term benefit and how the trial design really does help explain why we see such great results throughout the 2 years. Speaker 700:29:58Very helpful. Thanks. Operator00:30:03And our next question is going to come from Greg Harrison from Bank of America. Please go ahead. Speaker 800:30:10Hey guys, good afternoon. Congrats on the progress and thanks for taking the question. Just thinking through the IGAN treatment landscape And when it comes to comparing different treatment options, especially in light of recent data, is it fair to say that the focus for investors should be on the EGFR benefit or is there a better way to think about it? Speaker 200:30:32Greg, thanks so much for the question. I think the very short answer is no, but I'm going to let Jula talk a bit more about what she as a nephrologist and what she's hearing from thought leaders about the evolving treatment landscape and the importance of eGFR and proteinuria. Dula? Speaker 300:30:50Thanks. First, I'll start with proteinuria and eGFR both matter for how we take care of patients, but I'll highlight that proteinuria is really critical for nephrologists, for patients and for regulators We're evaluating and looking at risk as well as response to treatment over time as the proteinuria changes can occur more quickly versus the GFR changes require many years to show effect. And I would say importantly, multiple data sets show a strong correlation between protein That's why it's an approvable endpoint for accelerated approval. And we also know that we need to get patients as close to normal as possible. When you look at the rates, they still remain at risk if they've got 0.44 grams per day. Speaker 300:31:38So getting patients closer to normal with regards to proteinuria is very important. We saw 1 in 3 patients on FOSPARI in PROTECT achieved complete remission of proteinuria. And FOSPARI shows both reductions in proteinuria and eGFR preservation that accrues over time. So I think all those are important factors to take into consideration. Operator00:32:10I'm sorry, go ahead. Speaker 200:32:13No, no, no, please go ahead. I was just thanking the last Operator00:32:17Okay. Our next question is going to come from Anupam Rama from JPMorgan. Please go ahead. Speaker 200:32:25Hey, guys. Thanks so much for taking the question. A little bit more of a kind of an acute question as we think about in the Q1, any guidance about how we should be thinking about payer reauthorizations and Any seasonality considerations in the quarter? Let me just first say that Peter's team has done a really great job starting the year strongly and we've seen good performance. Peter, why don't I turn it over to you to talk a bit more about what we expect to see in those dynamics for Q1, recognizing that we've not and will not be guidance, but I think certainly Peter can talk about some of those dynamics in more detail. Speaker 200:33:09Peter? Speaker 400:33:11Yes, happy to, Eric. Yes, as I mentioned earlier, I think the across the three core fundamentals of launching a product, I think we made really substantial progress. And in particular, like ASN, I think, really allowed for building that momentum. We saw like an increase of prescriptions, in particular from thought leaders. So we also saw like a good progress in our pulse through in getting patients on base product. Speaker 400:33:36And I think Across the fundamentals, we see that continuation of progress in the 1st 6 weeks of this year as well. I think to your more specific question like What is the insurance reset and reauthorization criteria meaning for the gross to net in the Q1? Well, this is the 1st year we launched So that's going to be a new learning. So we don't know that yet. But if I look at the fundamentals, I'm really pleased with the progress we have been making. Speaker 400:34:07Thanks so much for taking our question. Speaker 200:34:10Thank you. Operator00:34:12And our next question is going to come from Tyler Van Buren from TD Cowen. Please go ahead. Speaker 200:34:20Hey, guys. Good afternoon. Thanks for taking the question. So as part of the sNDA submission by the end of the Q1 for the full approval for Does that include a request to have the black box and REMS warning removed? And if so, can you describe to us how you supported that request? Speaker 200:34:40Thanks so much for the questions, Tyler. Jewel, why don't I first turn to you to talk about the data that we've seen from a safety standpoint. And then, Bill, certainly you can add what we're thinking in terms of engagement with FDA during the sNDA process. Speaker 300:34:57Thanks. So I want to highlight that across our development program and 1st year of commercial launch, including patients who we've had in some of our trials on treatment for up to 10 years, we have had full cases Now I do want to note that there isn't historical precedent removal of the Bill, do you want to comment further on our process? Speaker 600:35:30Yes. With the anniversary of the approval, we will be submitting our 1st annual REMS update, which will highlight the data that we've collected around liver safety and we'll also be submitting the sNDA this quarter, which will give the full 2 year data in the PROTECT study. Both of those give us a launching point to begin the dialogue around a potential modification of the REMS program. At the end of the day, we need to start this dialogue. We don't know what the FDA's response will be, but it's really important for us to have the data that we have now and to begin the conversation and these interactions with the agency. Operator00:36:25Okay. And our next question will come from Carter Goode from Barclays. Please go ahead. Speaker 700:36:31Good afternoon. Thanks for taking the question and congrats on the pickup in sales. A lot of mentions of momentum and reflection on the call there. The new start form increase was somewhat more modest. I guess I'm trying to understand, Is that sort of mid single digit increase in new start farms probably a fair characterization of what we should expect going forward until those inflection points that Peter mentioned sort of hit because it does seem like those are back end weighted. Speaker 700:37:02Any color or commentary would be appreciated. Thank you. Speaker 200:37:06Carter, thanks so much for the question. I'd say that Peter can speak to Some of the qualitative and directional approach that we expect to see throughout the year for both patient start forms and demand, We will not be providing guidance on those for the year, but we certainly do expect to see a strong year of our performance, particularly in revenue. But Peter, why don't you talk in a bit more detail about what we can expect to see moving forward? Speaker 400:37:38Yes. Thanks, Carter, for that question. I think it's the characterization that you have You have to take it into context of a prescriber base that had very little innovation in the last 30 to 40 years. And So I think the adaptation, it takes time to educate the broad community and get to the prescriber base. And within that context, I think the growth that we are showing in Q4 and basically in every quarter in the 1st year, and I think what I called out earlier is that this is the first Recent revenue for our G and A, you see that continual growth. Speaker 400:38:14I think that is something that with the data we expect this year, the guidelines to be updated that there is a good momentum to show continuation of growth in patient start forms and more importantly, ultimately in revenue as well. So I think I understand your question, but yes, I think you have to take it into consideration with an audience that is maybe not used to that much innovation and really requires Like the education, with the experience that they're gaining, and that's what we are seeing right now, is the best advocate for further use and further prescription. And That's where we are right now. So I think in the 1st year of plans to have the continued growth that we saw, I'm really pleased with. Speaker 700:38:53Very helpful. Thank you. Operator00:38:57Our next caller is going to be Murray Raycroft from Jefferies. Please go ahead. Speaker 200:39:04Hi, congrats on the progress and thanks for taking my question. For the EU, you initially had filed for conditional approval and It sounds like that's what you're expecting this quarter, but then you submitted the 2 year data to the EU, which led to the clock stop. So is it possible you could get full approval in the EU? I guess is there any possibility for that or will it still be conditional? And has EMA provided any feedback after reviewing your 2 year data? Speaker 200:39:34Maury, thanks so much for the question. Bill, I will pass that over to you. Speaker 600:39:39Sure. Well, we remain optimistic about the positive CHMP decision that will be made this Q1. The 2 year data I think was helpful for the EMA in making their decision because it essentially removes the regulatory risk associated with their equivalent of accelerated approval. There wasn't discussion of potential full approval And there are aspects of the data package that they don't have yet. The full tables, figures and listings weren't provided more of a top line, look at the 2 year data. Speaker 600:40:17So I wouldn't expect a full approval with this round. Speaker 200:40:24Got it. And has EMA provided any feedback after seeing the 2 year data that they've seen? Speaker 600:40:31No, there wasn't an opportunity in the process for feedback from that. At this point in time, I'm sure we'll have dialogue as we go toward full approval. Speaker 200:40:45Got it. Okay. Thanks for taking my questions. Speaker 400:40:48Certainly. Thank you. Operator00:40:51Our next Person is going to be Tim Lugo from William Blair. Please go ahead. Speaker 500:40:57Hey, Ki Bin, this is John on for Kim. Thanks so much for taking our question. So just wondering if you have any sense on if the agency might require an AdCom to discuss conversion to full approval. And as a follow-up, if you have any sense on the last date that you might be informed that an income might be required? Speaker 200:41:17John, thanks for the questions. Bill, I'll pass that back to you. Speaker 600:41:21Sure. I don't think that this is the type of regulatory decision where the agency would seek advice from an advisory committee. I think the data is quite clear. So there isn't a need to go out to additional external to help interpret trial results. And I think also, there isn't a controversial aspect to this. Speaker 600:41:46So I don't anticipate that the agency will panel an advisory committee. Certainly, if they do, we will be ready. The second part of your question was the timing. Generally, the agency will let sponsors know within 60 days of submission, whether or not they're going to have an AdCom or not. So if we submit in the Q1 by mid to late 2nd quarter, we will know whether or not we're going to be going for an adcom. Speaker 400:42:20Very helpful. Thanks. Certainly. Operator00:42:25And our next question is going to come from Liisa Bayko from Evercore ISI. Please go ahead. Hi. Thanks for taking the question. Speaker 300:42:34Do you have any more color on when the new guidelines We'll be released. Speaker 400:42:43Do what? Speaker 300:42:46We know they're working on it now, but can't provide more color other than we were anticipating potentially this quarter and that means they would be finalized later in the year, but we know it's in the works. Okay. You mentioned compliance rates were good. And can you speak to kind of where you are with compliance? And then Also, can you describe growth to net for the year? Speaker 300:43:12Like what kind of average for the year you be thinking about or what would normalize, any color there would be helpful? Speaker 200:43:21Sure. Peter, I'll turn that over to you. Speaker 400:43:27I'll take the question on the compliance and Chris maybe you could take the gross to net then. So on the compliance rate, Like if you look at Bensmore for chronic disease without a non symptomatic disease, overall compliance rates are Not very high. What we see with Fiospari so far, it is actually really high. It's higher than what we anticipated, especially when you also program with like monitoring that requires monthly liver testing. So, so far, we see very strong compliance rates. Speaker 400:43:59I it speaks also to the experience patients are having, and that's for the first time they actually see that they're being controlled to the target levels. And I think you have to take into consideration, like a lot of those patients, they feel that they're losing. I mean, over the course of their disease, they hear every time from their physician that They're not yet on the target. And I think now with Stealthari, they feel like, hey, you know what, we are able to reach the target. And I think that is motivating patients to continue to use the product. Speaker 400:44:25And that's why I think we see also high compliance rates. Speaker 600:44:31And Lisa, just on the gross Speaker 500:44:32to nets, We've been pleased with how we've seen things meet our expectations of having a mid to high teens growth in that. The only thing that I would say is for 1Q with reset of the year, we may see that be a little bit higher as we have some of our other products in the past. But overall for the year, we would expect it to remain in that mid to high teens level. Speaker 300:44:52Okay. And then can you comment at all on like how many patients were on kind of exiting 2023 on VOSPARI? Speaker 200:45:04So we've not provided guidance for any KPIs on number of treated patients. I think Peter can talk about directionally what we were seeing as we ended the year. But Lisa, we're going to continue to provide updates on PFS, on payer coverage and on revenue at this point in the launch. Peter, you want to provide anything further towards this question? Speaker 400:45:33I think that's right, Eric. As I mentioned earlier, I think we're making robust progress on all the fundamentals, including the pull through getting patients on base product. I think the process is well within benchmarks, you would expect from rare disease products. And so I think we will see that continuation and it will be reflected by revenue as well to Iris' point. Okay. Speaker 400:45:57Thanks. Thanks, Lisa. Operator00:45:58Our next question is going to come from Pramil Divan from Guggenheim. Please go ahead. Speaker 900:46:05Great. Thanks for taking my question. Maybe just a couple of follow ups on the payer side. So I think, Peter, I think you mentioned in your Prepared remarks that the payers are they're sort of acting generally consistent with the label in terms of the patients that they're reimbursing therapy for. I'm curious if maybe you can just give a little more detail there in terms of when they're deviating from the label, sort of what issues, if any, are they sort of raising? Speaker 900:46:31And then the second question I have is more around the full approval, assuming you get that sort of later in this year. Would you expect sort of immediate change in sort of payer behavior on that? Or is that something we probably have to wait until So the 2024, 2025 cycle starts up in terms of formulary status or authorizations. Speaker 200:46:55All right. Peter, I'll hand this over to you. Speaker 400:46:59Yes, very good. With regards To authorization criteria, I mean, there's always certain aspects that the payer is expecting to see. And so I think where we are is that, Especially in the beginning when we got the label and the label was kind of fake on patients with rapid progression of disease with regards to proteinuria states like generally 1.5. When we are seeing that payers in most of the authorization criteria refer to the label, but Also refer to the clinical guidelines, and that has lower proteinuria targets, so that allows for a broader use. And that's why to my earlier point in the call, With a further lowering of the proteinuria targets within the Codigo lines, accompanied with like a broad label for filsparin And this allowed them also for a broader patient population that is eligible for paid products. Speaker 200:47:52And then Peter, what is your comment on the question around full approval and how payers will respond full approval on how quickly they might be able to review? Speaker 400:48:04Yes. So I think it speaks a little bit to what I said. There's a further lowering of proteinuria targets and then Also a broader label where there is no restriction in proteinuria, that authorization criteria on a threshold of proteinuria may disappear, and so that allows for a broader patient population. I think that's one aspect. I think another aspect is, and I think your question may have been Referring to like the evolving competitive landscape as well with new competition coming in, I think the lead times that we have and the strong base that we have in formulas provides a very strong position, especially since we have like the highest standards for study design. Speaker 400:48:44I mean, this is the only study that has competitive competitor, which is basically the gold standard, how a payer is evaluating new product. I think we are in a strong position with regards to lead time as well as study design and how payers are evaluating that in the evolving landscape. Speaker 900:49:07Okay. Thank you. Operator00:49:10And our next question is going to come from Alex Thompson from Stifel. Please go ahead. Speaker 1000:49:16Yes, great. Thanks for taking my question. I want to Maybe could you talk a little bit about the HARMONY study through your expectations around enrolling 70 patients or at least up Based on your experience with the Phase onetwo, how well identified are these patients? If this is a 12 week primary endpoint, Top line, is the 2026 readout conservative at this point? Or how are you thinking about that? Speaker 1000:49:43Thanks. Speaker 200:49:45Alex, thanks so much for the question and also for the focus on the pegmatinase program. Jula, I'll turn that one over to you. Speaker 300:49:54So thanks. We think this is an exciting trial design that focuses on changes in total hemophilia, not just at 6 to 12 weeks, but also looking at durability of effect. So it is a 24 week study and then patients roll over to our open label, which is able to look at diet liberalization. And to your point, we are looking to recruit 70 patients from more sites than we did from COMPOSE. It's about 50 sites overall, which will give us top line data in 2026. Speaker 300:50:21And while we have started the trial and we do have a list of patients who are excited to participate, We are intentionally moderating our enrollment initially to ensure we have a good experience for the sites and patients and also proper training at some of these sites who some of which are research naive and then also to ensure our CMC scale up to support the full study as well as commercialization. Speaker 200:50:45So I think perhaps if you can comment on the enrollment period before for screening that it helps explain why the timeline may be a bit longer than what people would typically say for this type of trial. Speaker 300:51:02Yes, thanks. So because it is a 6 month trial, plus we have a 10 week run-in period where patients get screened to make sure they qualify as well as standardize their diet and that's really to try and optimize our chance of success that patients have understand the trial that they need to keep their diet table, which clearly is going to impact your endpoint. We want to maximize our chance for success at the end. So it's a bit longer than what you first stated? Speaker 200:51:30Yes. And we'll certainly look to move swiftly on this, but we for all of the reasons that you'll have explained, We've been very thoughtful around the timelines that we've put out there. Alex, the only other thing that I would mention that we that gives us confidence in the enrollment is that as we see increased awareness within this community, There are more and more patients that are being identified and we would absolutely expect that there will be a growth in the number of patients identified diagnosed in the overall market growth. So this is something that we believe will certainly be a tailwind for us with the HARMONY trial and even more so as we look to reach these patients once we have approval. Speaker 1000:52:17And I guess, How many patients do you feel like you need to enroll to feel confident in powering if it's not 70? Speaker 200:52:27Bill, why don't you talk about the powering? But I can say we absolutely are confident in finding these patients. I think we've been able to help in thinking through where these patients are, which sites, etcetera. So I think, JUULA's team has done a really great job of ensuring how we can enable success in the HARMONY trial. So I think Bill you can talk about a high level of the powering. Speaker 600:52:50Yes. No, certainly, and I appreciate the question. We're very confident in the powering of the study and recall in Julia's initial remarks, she mentioned the 67% reduction in total homocysteine that was observed in Phase II. So with that level of efficacy, even with a significant diminution in the treatment effect or a reduction in the overall total sample size, which we don't anticipate, we certainly are in a good place to still achieve the endpoint. So, I'm confident that we'll get there. Speaker 500:53:46Jenny, can we move to the next question please? Operator00:53:52Yes. We have Mohit Bansal. Can you hear me? Speaker 200:53:56Yes, I can. Yes, we now can. Operator00:53:58Okay. Speaker 1100:54:03So I did not hear you at that point. Sorry about that. Thank you very much for taking my question and congrats on the progress. Just wanted to understand, I mean, I know you don't provide the patient count, but if I look at the average number of patient forms, I mean, from Q2 to Q3 and then quarter to Q4, it seems like there's a 57% increase, but then there's a substantial increase in revenue. So Is this because you are converting a lot more of those patients form into paid patients Or is there a stocking part involved here? Speaker 1100:54:40Can you help us understand that? And then last second question is On the price increase, I think you took a price increase in January. Should we expect some benefit in 2024 due to that price increase? Thank you. Speaker 200:54:53Okay. Thanks so much for the question. Peter, I will turn that over to Speaker 400:54:57you. Yes. So, thank you, Mohit, for that question. So, as I mentioned, like one of the core fundamental is making sure that patient starts from transition ultimately to patients' own products and in particular patients' own paid products, so you continue to increase the revenue. And I think what you saw in this quarter is that we made robust progress, In particular, also on the pocket of patients that we described in the earlier quarter, which that required some additional handholding and education with As I mentioned, like the patient REMS certification was in the 1st 14 days has increased quite substantially, and that allowed patients to go through the process and get to base product more quickly. Speaker 400:55:47So Good progress there. To Erik's earlier point, we don't provide further details on how many patients we have on product, but I think The transition from patients' platform to ultimately a patients' paid product, we made significant progress. On the second question with regard price and price increase, indeed, we had a price increase in the beginning of the year. Now that we have the confirmatory data and you see that the proteinuria Reduction, the robust pottery reduction provides longer term eGFR and kitten preservation as well. So we thought it was justified to have a price increase for this year. Speaker 600:56:28Got it. Speaker 200:56:29And maybe just one final thing, Mohit, for your question on inventory, that has been stable. So there has been no pattern of stocking. So I think Peter is absolutely right. We expected to see a greater inflection in revenue as our teams are able to help those patients through the process. You would imagine that that is going to continue that trend this year with faster growth in revenues than perhaps what we see in patient start forms, but we'll certainly apprise you how we're doing at the Speaker 400:57:00end of Q1. Thank you. Operator00:57:06And our next question is going to come from Yigal Zhokomovitz from Citi. Please go ahead. Speaker 1200:57:17Hi, Travir team. Thank you very much for taking the questions. I had one on FSGS. Just curious if there were any recent updates With regard to the work that I believe the FDA is doing in collaboration with you on defining some of the optimal endpoints For FSGS, whether there's some variations of the EGFR slope endpoint that may be more appropriate based on some of the data cuts that you're exploring? And then secondly, on the broader landscape in IGAN, just wondering, obviously, there's been a lot of visibility around some of the newer mechanisms, anti B cell mechanisms. Speaker 1200:57:50Wondering whether Filspari, given its position as a foundational therapy, may benefit from a combo study using the B cell modulators on top of ZOSPARI at a future point? Thank you. Speaker 200:58:05Great. Thank you for the questions. And July, we'll turn those over to you. Speaker 300:58:11Thanks. As far as FSGS, we are continuing to do our analysis with our data and then external data sets our trial data into historical context. With regards to the FDA, this is a partnership with NEFCure, which is a patient organization with academics and the FDA and it's called Parasol. There's a website, it's public. And it's really to redefine the endpoints. Speaker 300:58:34And What they've recently announced is they're really looking at alternative proteinuria based endpoints to help enable the regulatory pathway for SGS. We plan to reengage the FDA following their final analysis and decision on what those endpoints should be under this Parasol group, and they're targeting ASN for that timeline. And then your second question is around some of the newer agents and how should be placed. And I think it's really going to be an exciting few years for IgA nephropathy patients with some of these new therapies, most of which target different parts of the injury cascade contributing to IgAN and hopefully they'll become available outside the context of a clinical trial, but we're a few years away from that. But I would add that all additional immune modulating agents are being used on top of standard of care foundational treatment. Speaker 300:59:26And that's where so Safari plays a foundational role because it targets the injury in the kidney and the response to the GDIGA deposition and protects against further damage. And really, we're really aligned with the KOLs. You need to target 2 things, the ongoing damage in the kidney with foundational treatment. And to your point, you could potentially add another agent that targets upstream pathways, that's additive. As far as other trials, I think it's important to realize that every other trial is studying a new agent on top a standard of care. Speaker 301:00:01And many of those trials now because of Sillsbury superiority over ACEs and ARBs, They're being allowed as part of the foundational standard of care. So we will get data over time from these trials as they read out about the combination and then being used together. Speaker 201:00:20And we certainly are interested That combination and generating additional data, I'm very proud of Jules' team, where we do have 2 ongoing studies looking at the combination of Vilspari plus SGLT2. I think some of the few combination studies that have yet been initiated, we would expect that that could potentially increase as other therapies are actually approved. Speaker 1201:00:45Great. Thank you very much. Operator01:00:48And our next question is going to come from Ed Arce from H. C. Wainwright, please go ahead. Speaker 1301:00:55Hello, everyone. Thanks for Congrats on another quarter of progress. A couple of quick questions for me. Firstly, with With regards to the sNDA later this quarter for FASPARI for approval, Just wondering if you could confirm the length of the review period that you would expect 6 or 8 months or would that roll into some next year. And then secondly, as I look at the PSF Quarter over quarter so far in last year, and as those growth rates moderate a bit, I'm wondering if you can discuss Some of the 2 inflection points that have been mentioned before later this year, the Codigo guidelines and the upcoming data analysis from ongoing trials, especially the SGLT2 combo. Speaker 1301:01:54What impact and I Speaker 401:01:57guess this Speaker 1301:01:57is a question more for Peter, but what sort of subjectively What impact would you expect those to have on treating physicians as they get more experience with the drug. Thanks. Speaker 201:02:15And thanks for the questions. Bill, why don't you take the regulatory And then Peter, you can take the PSF outlook question. Speaker 601:02:26Yes. We expect to have priority review Out of, for this, SNDA that would be consistent with how the agency treated a predecessor that went just recently before us. In that case, it would be a 6 month review. So you'd have a Q3 decision. If we were standard review, it would take to the end of the year. Speaker 601:02:50So in either case, we have a decision this year. I'll Pass over to Peter for the rest of your question. Speaker 401:03:01Yes. Thanks for that question. I think there's really two elements that I would like To point you to, with regards to the evolving landscape, with regards to the guidelines as well as a broader label and what would that mean for the potential for patient start forms in the future. I think there's 2 core elements. 1 is the urgency to treat or better the urgency to change. Speaker 401:03:26With further emphasis, you have to go lower. Protonuria at the level of lung is still not where you need to be. And I think last year, the radar data got published from the U. K. It's registry data, and it shows that even with a proteinuria of 0.9, those patients actually have doubled the progress to end stage kidney disease compared to patients that have an opportunity level of in average of 0.44. Speaker 401:03:51So I think these kind of data and then reinforcement in the guidelines further amplifies the urgency to change for those positions and change that foundation that is currently ASMRs and replaced it with a much more efficacious treatment like Filspari. And just to recall, I mean, the proteinuria benefit that Filspari had after 9 months was 3 fold, 15 versus 15. But after 2 years, it was actually 10 fold. So I think that is an important aspect. So the urgency to change, I think, is one aspect. Speaker 401:04:26The second one is really it allows for a broader patient population. And What we have highlighted earlier is that we said at launch, we expect to have an addressable patient population for Filspari between 3,050,000. We think with the broadening of the label as well as further highlight of the KANU guidelines to go to a lower proteinuria target, we think there is up to 70,000 addressable patients fulfill sparing. So I think those are the 2 core aspects I would want to highlight with regards to the evolving landscape and what it means for the addressable patient population and potentially patient starts for TOSFARI. Speaker 201:05:03Thank you, Peter. Julia, is there anything that you'd like to add? Speaker 301:05:06Yes, thanks. I think it's we have a couple of inflection points and Peter nicely highlighted CAGIGO to treat patients earlier and diagnose them earlier. And then the SGLT2 combination, we know that combination therapy is going to be important So we think those are 2 things. But the third thing that I want to point out is with regards to the earlier treatment. We have a trial called Spartan where we utilize early after they first get diagnosed and they're RAS naive. Speaker 301:05:33We presented some of that data at ASN and it shows Earlier, we've seen 80% reduction in proteinuria. Most of the patients getting into complete remission and no change in eGFR over 36 That trial has been continuing. We'll have additional data on that over the years. But, I think that's an additional point as far as treating patients earlier in their disease course. Speaker 201:05:56Yes. Thank you, Peter and Julien. Maybe if we just take a step back for a moment, if we put ourselves towards the end of 2024 And you assume that we have a full approval with a potential broader label just as the Codigo guidelines potentially lower the target and really increase the dynamism in the treatment of patients with IgA nephropathy, We really will be at the right place at the right time. And if you think about also all of the clinical experience that physicians are getting with VILSPARRI. There's one thing that we know from this launch and hearing from physicians and their patients who are on PILspari. Speaker 201:06:40It is a very rapid and consistent reduction in proteinuria. We believe that we'll be in the right place at the right time. And I think our goal is to make sure that we continue to expand for new physicians to be able to get that clinical experience. And we believe that positions us very strongly for future growth. Speaker 1301:07:01Great. Thank you so much. That's very helpful. Operator01:07:05And our next question is going to come from Laura Chico from Wedbush Securities. Please go ahead. Speaker 1401:07:11Hey guys, thanks very much for taking the question. I'd like to shift gears and ask one on pegdevatinase. And Eric, your comments there about kind of the phenomena we see with orphan disease and the expansion of patient populations over time. I apologize if I missed this, but do you plan to keep a patient registry with respect to HCU? And Kind of related to that, would you be able to disclose an identified patient number as you're going along? Speaker 1401:07:38Thank you. Speaker 201:07:41Great questions, Laura. Yes, we do have a registry and we do continue we plan to continue that. We think that that's an incredibly important source of information for the community. And it's really a great question around sharing patient information or identification. That's certainly something we know others have done. Speaker 201:08:01We'll be looking at the potential for us to be able to do that as well. Can't commit to it today, but absolutely something that our team is looking at. Speaker 1401:08:10Thanks very much guys. Operator01:08:16And this will conclude the question and answer session of today's conference call. I'll hand the call back over to Anne. Please go ahead. Speaker 101:08:25Great. Thank you, Jenny, and everyone for joining us for our Q4 and full year 2023 financial results call. We look forward to providing additional updates on our progress. Have a great rest of your day. Speaker 401:08:43Alright. Operator01:08:50And this concludes our call. Thank you for your participation. You may now disconnect.Read morePowered by
