Operator00:00:00Good morning, and welcome to Agios' 4th Quarter 2023 Conference Call. At this time, all participants are in a listen only mode. There will be a question and answer session at the end. Please be advised that this call is being recorded at Agios' request. I would now like to turn the call over to Chris Taylor, Vice President, Investor Relations and Corporate Communications for Agios. Operator00:00:20Please go ahead. Speaker 100:00:24Thank you, operator. Good morning, everyone, and welcome to Agios' conference call and webcast to discuss 4th quarter and full year 2023 Financial Results and Recent Business Highlights. You can access slides for today's call by going to the Investors section of our website, agios.com. On today's call, I'm joined by our Chief Executive Officer, Brian Goff Doctor. Sarah Hewins, Chief Medical Officer and Head of Research and Development Sveta Milanova, our Chief Commercial Officer and Cecilia Jones, Chief Financial Officer. Speaker 100:01:02Before we get started, I would like to remind everyone that some of the statements we make on this call will include forward looking statements. Actual events and results could differ materially from those expressed or implied by any forward looking statements as a result of various risks, uncertainties and other factors, including those set forth in our most recent filings with the SEC and any other future filings that we may make with the SEC. With that, I'll turn the call over to Brian. Speaker 200:01:30Thanks, Chris, and good morning, everyone, and thank you joining us. Our mission at Agios is to develop and deliver transformative medicines that elevate and extend the lives of patients living with rare diseases. Driven by this goal, we continue to generate consistent and compelling data across our industry leading PK activator franchise. And with seamless cross functional collaboration of the Agios team, we made remarkable progress advancing this mission in 2023. Highlighting this progress, we reported 3 key data readouts in the last 12 months. Speaker 200:02:09In June, we reported positive top line data from the Phase 2 portion of the RISE UP study of mitapivat, our lead PK activator in sickle cell disease followed by the full data set in December at ASH. Despite the field's recent progress in sickle cell disease, there are no novel oral therapies that both improve anemia and reduce sickle cell pain crises and that is precisely what we aim to deliver with mitapivat. In November, we reported positive data from the open label Phase 2a study of our other PK activator AG-nine forty six in lower risk MDS with 40% of patients achieving the transfusion independence endpoint. And just last month, we reported positive data from the Phase 3 Energize study of mitapivat in non transfusion dependent thalassemia. As a reminder, non transfusion dependent or NTD thalassemia accounts for approximately 2 thirds of thalassemia in the U. Speaker 200:03:14S. And has no FDA approved treatment option. Despite not requiring regular transfusions, NTD thalassemia patients experienced significant impact on quality of life, a wide range of serious morbidities and an elevated risk of premature death. Together, the consistency of data generated across the mitapivat development program bolsters our conviction in the probability of success of our ongoing studies, including 2 additional Phase 3 readouts we expect by the end of this year. And this data highlights the potential of our PK activators to transform the course of multiple hematologic diseases. Speaker 200:03:59Sarah will provide more detail on our advancements and upcoming milestones across our pipeline in just a few minutes. Importantly, we believe our PK activation pipeline is well positioned with multiple near term catalysts to become a multi $1,000,000,000 franchise and deliver significant value. In parallel with advancing the late stage mitapivat development program across multiple indications, our commercial organization is laser focused on building the infrastructure established through our current launch in PK deficiency to prepare for potential U. S. Launches of mitapivat in thalassemia in in 20 25 and in sickle cell disease in 2026. Speaker 200:04:45Sveta will provide greater detail on the commercial opportunities for mitapivat in thalassemia as well as an update on our current launch in PK deficiency in just a bit. Finally, as you'll hear from Cecilia, we ended 2023 with a strong cash position with approximately 806 $1,000,000 in cash and investments on the balance sheet. In addition, we continue to track Servier's progress towards the potential FDA approval of vorasidenib given our retained economics for both the milestone and royalties. This is truly an exciting time at Agios with 4 additional Phase 3 readouts and 2 potential launches expected on the horizon. We look forward to multiple opportunities to drive significant near term value creation for patients, caregivers and shareholders. Speaker 200:05:40With that, I'll now turn the call over to Sarah. Speaker 300:05:44Thanks, Brian. In 2023, our research and development organization made tremendous progress advancing our PK activator development program. Led by Metopimab, the industry's most advanced PK activator now with over 8 years of clinical experience, the consistent and compelling data we have generated to date in PK deficiency, Thalassemia and sickle cell disease continue to derisk our ongoing development program and highlight for this molecule to transform patient's function and quality of life. We are also enthusiastic about the potential Operator00:06:24for the rest of our growing pipeline, Speaker 300:06:24and we are pleased to note that we remain on track to deliver on our milestones, including enrolling the first patients in the Phase IIb trial for AG-nine forty six in lower risk MDS and for the Phase I trial for HE181, the compound name for our PAH stabilizer for phenylketonuria. Reading out top line data for the Phase III ACTIVATE KITs P study in regularly transfused pediatric patients with PK deficiency and completing enrollment of the Phase 3 ACTIVATE KIT study in pediatric patients with CKD. Turning to sickle cell disease, we were pleased to present detailed positive results from the Phase 2 portion of the Phase 2, III RISE UP study of mitapivat at ASH in December. The study achieved its primary endpoint of hemoglobin response And in addition, an improvement in annualized rates of sickle cell pain crisis was observed. And we have been delighted by the enthusiasm of the investigators. Speaker 300:07:25We continue to advance enrollment in the Phase 3 portion of this study and remain on track to complete enrollment by the end of this year. While the treatment landscape in sickle cell disease continues to evolve, there remains an urgent and unmet need for convenient novel oral treatment options that address both anemia and sickle cell pain crises. And we believe firmly in the top of our potential to deliver a best in class option for patients from this devastating disease. And finally, on thalassemia, I'll take a moment to highlight a few key elements of our program and the positive top line Phase 3 data we reported last month in non transfusion dependent thalassemia. As a reminder, the Phase 3 program of spirokinin thalassemia and compacting 2 Phase 3 randomized placebo controlled trials was designed to deliver data across all populations of thalassemia, such as alpha and beta thalassemia and populations with different transfusion needs. Speaker 300:08:26Both trials enrolled patients with alpha or beta thalassemia, but enrolled different populations as it relates to transfusion needs. We want to highlight that Energize is the 1st clinical program that included patients who were not regularly transfused and alpha thalassemia patients. As Brian mentioned, there are no FDA approved treatments for non transfusion dependent thalassemia, which represents approximately 2 thirds of total thalassemia patients in the U. S. These patients suffer from a poor quality of life, a high rate of serious morbidities, including thrombosis and premature death. Speaker 300:09:02We were therefore very pleased to be able to announce positive results from the Energize study. As a reminder, the Energize enrolled a total of 194 patients with either alpha or beta non transfusion dependent thalassemia, randomized 2:one to 100 milligrams nizapagat placebo twice daily. The speed of enrollment and the actual number of patients enrolled in the study as well as the high completion and rollover rate supports the idea that people who are not regularly transfused were motivated to take action and speaks to the unmet need for this population. The primary endpoint of this study was hemoglobin response rate defined as an increase of at least 1 gram per leader in average hemoglobin concentration from week 12 to week 24 compared to baseline. The key secondary endpoints of the were changed from baseline in average rapid fatigue score and changed from baseline in average hemoglobin concentration, also both assessed from week 12 to 24. Speaker 300:10:02On the primary endpoint, treatment with mitapivat demonstrated a highly statistically significant result with 42.3% of patients in the treatment arm achieving a hemoglobin response versus 1.6% of patients in the placebo arm. In line with mitapivax novel mechanism of action, which focuses on overall red blood cell health and the data generated with mitapivax across additional disease areas, the beneficial effects of mitapifat in this study extended beyond hemoglobin alone. Specifically, treatment with 100 milligrams mitapifat resulted in statistically significant improvements in both key secondary endpoints, including a change from baseline in average facet fatigue score, an important patient reported measure of how patients feel and function. Importantly, across the primary and secondary endpoints, All pre specified subgroup analyses favored nipativat compared to placebo, suggesting that no single subgroup was responsible for driving the results, which supports our plan to file for a broad label covering all thalassemia subtypes. This is therefore the first drug that not only improves hemoglobin, but actually makes people with thalassemia feel better, consistent with what we observe in patients with PKD and what we hope to be able to deliver for patients with sickle cell disease as Complementing the near term benefit of thalassemia patients reporting that they had less fatigue and felt better in the near term, Clinicians in the trial and other KOLs appreciate the potential longer term benefits of reducing markers of hemolysis and the longer term potential to reduce serious morbidities. Speaker 300:11:43We are very much looking forward to presenting the full data set at a medical meeting. Beyond the excitement we have for the ENERGISE data itself, the readout of the ENERGISE trial also gives us further confidence towards the readout of ENERGISE Thalassemia is a hemolytic anemia irrespective of whether a patient is in need of transfusions or not. In addition, the mechanism of action of mitapivat is not dependent on the need for transfusions. We have already demonstrated an improvement in hemolytic anemia in the ENERGiSE trial with a positive change in hemoglobin. We are now waiting to see if the improvement in hemolytic anemia can also be documented via a reduction in transfusions in Energize T. Speaker 300:12:28As a reminder, the primary endpoint of Energize is transfusion reduction response defined as a 50% or greater reduction in transfused red blood cell units with a reduction of equal or more than 2 units of transfusion dependent allopathy in any consecutive 12 week period through week 48 compared to the baseline. Like the ENERGISE study in non transfusion dependent allassemia, the design of the ENERGISE E trial enables us to demonstrate clinical meaningfulness in a variety of ways via reduction in transfusion burden, which also includes transfusion metrics in line with that other studies have used. We designed this study incorporating learnings from prior studies and agency feedback and believe a dynamic assessment period is important as patients aren't We look forward to the readout of this study by mid year and plan a single regulatory filing to the FDA encompassing data from both Energize and Energize P by the end of this year, seeking a label that will enable people living with thalassemia access a convenient and differentiated oral treatment option. Overall, I'm very proud of the tremendous progress made by our R and D organization in 2023 and look forward to continuing this momentum in 2024. Speaker 400:13:43With that, I will now turn the call over to Sara. Thanks, Sarah. Celotemia remains an area of higher met need with few treatment options. The burden of disease on the patients is significant regardless of their transfusion needs. Thalassemia patients experience increased mortality compared to the general population and can be significantly worse in non regularly transfused than those who are regularly transfused. Speaker 400:14:17Patients endure high rates of morbidities and increase complications as they age. Adult patients with non transfusion dependent thalassemia may actually have similar or worse quality of life compared to transfusion dependent patients. Of course, this burden of disease correlates to increased health care costs. To address this unmet need and galvanized by the positive data from the Phase III energized study of mitapylak, Our commercial organization is actively preparing for a potential launch in Telotenia next year, beginning with the U. S. Speaker 400:15:04In the U. S, there are approximately 6,000 diagnosed adult patients with thalassemia. Approximately 4,000 of these patients are non transfusion dependent and have no available treatment options today. The remaining 2,000 patients are transfusion dependent and have no oral treatment option. Our goal with mitapivax is to address the nonmet need of all adults living with thalassemia and become the 1st therapy approved for all the types of the disease. Speaker 400:15:47In addition to the data we are generating through the mitapivac clinical development program, there are 3 key factors we believe have the potential to support adoption of mitapiva among thalassemia patients in the U. S. First, there is strong alignment between where in the U. S. These patients reside and where they receive treatment. Speaker 400:16:13The map on Slide 20 depicts patient prevalence Overlaid with the Agios clinical trial sites and or centers of excellence represented by the gold stars. 2nd, the diagnosis rate is high, driven by availability of newborn screening and well established ICD-ten codes, many patients are diagnosed before adulthood. And finally, as shown on Slide 21, There is concentration of patients and providers at selected centers. Approximately 50% of all diagnosed patients are treated as fewer than 150 affiliated hematology oncology practices in the U. S, providing a clear focus for our initial launch. Speaker 400:17:07Given this market dynamic and ThyroKymes target product profile, we believe we are well positioned to provide a potential foundational treatment options for patients with thalassemia regardless of subtype. Therefore, our team is focused on 4 core areas of U. S. Launch preparation. 1st, building on the foundational work we have already done, We continue to deepen the sophistication of our market understanding. Speaker 400:17:39We are conducting extensive market research and claims data analysis to inform ATP targeting, field force sizing and deployment for launch. 2nd, we'll be rolling out a disease education campaign for both patients and clinicians, highlighting the long term complications and burden of disease across all thalassemia subtypes. Our disease education engagement will also work to correct the historical misperception that non transfusion dependent patients are less likely to experience the debilitating long term effects of thalassemia. To support these initiatives, we are establishing capabilities to enable execution of our educational efforts across personal and non personal channels. 3rd, we will continue to strengthen our commercial capabilities by expanding our sales team in anticipation of the thalassemia launch, rightsizing the team for a broader rare disease. Speaker 400:18:46And lastly, in parallel with those efforts, we are preparing our market access team to engage with payers on disease safety education in advance of the potential launch in thalassemia next year. Our team has obtained in market access for PGA deficiency, and we look forward to watching them pave the way in Telestinia, too. In addition to the well established U. S. And Lathemian market, there are approximately 13,000 patients in the EU5 and approximately 70,000 saluthenia patients in the Gulf region. Speaker 400:19:25We aim to maximize the potential of these additional markets through coordinated regulatory filings, which we intend to pursue with partners. Taken together, we believe the potential launch of mitotivat in thalassemia represents a significant opportunity for Agios and a step forward as we prepare for potential back to back launches with sickle cell disease in 2023. Now let me provide an update On the current launch of PyroKyne in PK deficiency. In the Q4 of 2023, we generated $7,100,000 in net Biopharma revenue compared to $7,400,000 in the prior quarter. A total Of 178 patients have completed a prescription enrollment form including 18 in the Q4 of 2023, an 11% increase versus the 3rd quarter. Speaker 400:20:29This translated into net 109 patients on therapy, a 9% increase versus the 3rd quarter. Patients on therapy continue to stem from a growing and diverse prescriber base of 154 physicians and represent a broader demographic and disease manifestation range that is consistent with the adult PK deficiency population. We continue to be encouraged by the persistency of patients on treatment and remain focused on efficiently identifying providers likely to treat patients with PK deficiency. The capabilities we continue to build and expand through the current launch, including Efficient targeting analytics, patient awareness and education and patient access will provide a firm foundation from which we can maximize the potential U. S. Speaker 400:21:27Launches in telatinia in 2025 and in sickle cell disease in 2026. As we advance through this catalyst rich period A Phase 3 data readout for mitapivat, we look forward to dramatically expanding the number of patients we serve. With that, I'll turn the call over to Cecilia. Thanks, Veda. Our Q4 2023 financial results can be found in the press release we issued this morning and more detail will be included in our 10 ks, which will be filed later today. Speaker 400:22:05Let me now take a moment to provide some context and highlight a few key points. Full year 2023 net Pyrocant revenue was 26 $800,000 compared with $11,700,000 in firecrane revenue for 2022. Q4 2020 City net Pyrocant revenue was $7,100,000 a 4% reduction compared to the 3rd quarter. The reduction was driven by lower number of weeks on hand of inventory compared to where we ended Q3, partially offset by favorability in As a reminder, we anticipate low levels of inventory at any given time given our limited distribution network, which consists of 1 specialty pharmacy and 1 specialty distributor. Consistent with other rare disease launches, growth to net is to be in the 10% to 20% range on an annual basis. Speaker 400:23:02Based on our learnings to date, Given the ultra rare nature of the disease and the long lead times associated with initiating patients on therapy, we continue to expect slow and steady growth and quarter to quarter variability in 2024, similar to what we saw in 2023. Cost of sales for the Q4 was 0.6 $1,000,000 R and D expenses were $77,000,000 for the 4th quarter 296 $1,000,000 for the full year 2023, an increase of $16,000,000 compared to the full year 2022. These changes reflect an increase in development costs for mitapivat and the upfront payments associated with the license agreement with Alnylam, offset by a reduction in expenses associated with the evolution of our research organization and the sale of our oncology business to Servius. SG and A expenses were $35,000,000 for the 4th quarter and $120,000,000 for the full year 2023, a decrease of $2,000,000 compared to the full year 2022. As a reminder, as part of the divestiture of our oncology business to Servier, We retain rights to a potential $200,000,000 milestone upon FDA approval of rasitanib and 15% royalties on potential U. Speaker 400:24:26S. Net Servier publicly communicated plans to file for approval before the end of 2023, so we are eager to track their progress. We ended the year with cash, cash equivalents and marketable securities of approximately $806,000,000 We expect that this balance together with anticipated product revenue, interest income and the potential vorasidenib milestone would enable the company to fund our operating expenses and capital expenditures through several value creating milestones and at least into 2026. This guidance does not include cash inflows that could extend the runway beyond 2026, including the potential royalties from ruxidinib, commercializing Mitepivat outside of the U. S. Speaker 400:25:16Through 1 or more partnerships or other potential strategic business or financial agreements. We remain focused on creating shareholder value, including by proactively managing our cost base and deploying a disciplined cash allocation approach As we prepare to support potential future launches of Paragon, as we move toward additional potential value creating milestones in the near term, I am confident that our strong balance sheet will enable us to execute from a position of strength as we continue to pursue ways to create shareholder value. I will now turn the call back over to Brian for his closing remarks. Speaker 200:25:53Thanks, Cecilia. As we turn the page on a highly productive 2023, We're focused on executing across the additional 4 Phase 3 readouts for mitapivat that we expect over the next 2 years, Beginning with the Phase 3 Energize T study in transfusion dependent thalassemia in the middle of this year. As we continue to stack successive positive data readouts for mitapivat, we are only growing more confident in the probability of success ahead. We're well positioned with a differentiated mechanism of action that improves red blood cell health beyond hemoglobin increase and allows us to pursue large commercial opportunities with substantial value and the potential for 2 additional first in class and best in class indications for pyracine as we build a multi $1,000,000,000 franchise in PK activation. As we continue to take steps toward realizing our vision of becoming a leading rare disease company, We will continue to strive to be responsible stewards of our balance sheet and evaluate meaningful opportunities for value creation. Speaker 200:27:08Finally, I'd like to thank all of our employees for their hard work and dedication to our mission of developing and delivering transformative medicines that elevate and extend the lives of patients living with rare diseases and all of our partners, including the patients, physicians, caregivers and participants in our clinical development programs. With that, we will now open the call for questions. Operator00:27:36Thank Our first question comes from the line of Eric Schmidt with Cantor Fitzgerald. Your line is now open. Speaker 500:28:12Well, thanks for the question and congrats on all the recent development I guess maybe one for Sarah, given the next milestone, next T milestone at least might be the Energized T study for mitapivant in Can you give us a little bit of a preview here or set up with regard to the primary endpoint? I know you're looking at transfusion reductions in a slightly different way than what we've been accustomed to seeing with the luspatercept data. So How might that primary endpoint definition change the way we view the data and what might the hurdle be? Speaker 200:28:49Great. Eric, thanks a lot for the question. And I just before Sarah goes, I just want to welcome you back to Agios earnings call. So Sarah, do you want to get started? Speaker 300:28:59Sure. Thanks for the question. So indeed, our endpoint, our primary endpoint has a different definition than the primary endpoint that was TATA Septu use in the sense that we are looking at a 50% reduction in any 12 week period rolling period basically over the 48 weeks that patients are assessed, which we believe is a more appropriate measure to assess a patient in the context of a dynamic disease over a longer stretch of time and which reflects better the real world experience that patients may have. We do have a similar endpoint like the luspatercept primary endpoint in our secondary endpoints. In regarding to the hurdles, It is a different endpoint indeed. Speaker 300:29:44The hurdle is not necessarily different in the sense that you have multiple assessment periods versus a fixed period in time. The bar of 50% of course is higher than 33%. But like I said, because it's every any 12 week period you have more shots on goal as to speak. This was an endpoint that luspatercept also had in their assessment and in their review, but as it was not a pre like primary or secondary analysis that did not make it into the label. Speaker 500:30:16Thank you very much. Thank you. Operator00:30:21Thank you. One moment for our next question please. Our next question comes from the line of Chris Raymond with Piper Sandler, your line is now open. Speaker 600:30:38Thanks. Maybe just a question on the Energize data that we got last month. We've gotten a few questions around from investors around the sort of the transition from the Phase 2 data to the Phase 3 data. There was a degradation in the hemoglobin response, but you measured these effects over different time points. I know you guys had said that there was no waning of efficacy over time, but maybe just square this difference that you saw? Speaker 600:31:07And then I've got a follow-up. Speaker 300:31:10Sure. Thanks for the question. So the primary endpoint that we used in a Phase 2 was indeed different than the endpoint that we used in the Phase 3, meaning that for the Phase 2, we just looked at patients meeting a hemoglobin response at a single time point. And for the Phase 3, we incorporated the duration in that endpoint over a longer stretch of time and measured at a later time point because it's a chronic disease. So then from a Phase 2 perspective, you're truly looking for maintenance over a longer duration of time. Speaker 300:31:45So we averaged hemoglobin over 12 weeks versus that just single time point, which is much easier to reach as a bar. In regards to the waning, we don't see waning of our hemoglobin response. So mitapivat in this trial behaves very similarly to how it behaves in PKD. So once patients show a response, they tend to maintain that response over time. There's always a little bit of fluctuation on the hemoglobin over time, but overall it stays positive and the line kind of stays horizontal in comparison to their baseline. Speaker 300:32:22So we feel very confident with the results that we have observed in Energize. In addition, it's more than hemoglobin alone that we observed. We really saw an improvement on the facet fatigue there as well, which we believe is extremely meaningful because Now we are adding to the hemoglobin plus story here. The things that we've observed in PKD now also have been observed in the non transfusion dependent population and that continues to add to this consistent and compelling data story that we are continuing to generate. Speaker 600:32:54Okay, thanks. And then maybe just a follow-up to Eric's question on the success bogey of Energize Tea. I know it's you're talking about different measures. It's not an apples to apples comparison to luspatercept. But Just as you're thinking about the obvious difference, admitted to that is oral versus luspatercept, which is not. Speaker 600:33:19Just maybe talk in generalities how you see these 2 compounds sort of coexisting commercially? Speaker 300:33:27Sure. So if we think about the non transfusion dependent thalassemia patient population, they currently have no therapy available. So that is Mitakova would if we get it through the next stages of development would be the therapy that it would The available for non transfusion dependent patient populations and is oral indeed, which is a huge benefit specifically for that population because patients aren't Going to clinic as frequently and if you have a drug that requires frequent clinic visits that adds to the burden of disease typically. For the transfusion dependent patient population, there is indeed subcutaneous Luspatercept available for transfusion dependent beta thalassemia patients, our program has studied All genotypes of thalassemia, so that's one difference. The oral route of administration here is very relevant because it allows for almost a seamless incorporation into a transfusion schedule that a patient may have versus requiring more visits on top of the transfusion schedule. Speaker 300:34:40In that sense, it's also important to understand there's a very different mechanism of action between those 2 products, which is a stimulator, red blood cell stimulator, while mitapivat It's trying to improve red blood cell health overall and so we do think from that perspective, they're vastly different. Speaker 200:35:02Yes. And Chris, I mean that last point is the one that I would just emphasize is that I know folks are trying to make comparisons, but in so many ways they're incomparable of the profound difference in the mechanisms and you'll hear a lot from us because we continue to be emboldened by this by the data that we see very consistently that the benefits of pyruvate kinase activation really do go beyond hemoglobin. So we'll await the data. Fortunately, we don't have to wait that long. Energize Tea is coming mid year. Speaker 200:35:35But I think above oral and the other dimensions, hemoglobin and the like, That's really the big headline for this mechanism is it's ultimately about red blood cell health. Operator00:35:46Thank you. One moment for our next question. Our next question comes from the line of Danielle Brill with Raymond James. Your line is now open. Speaker 700:35:56Hi, guys. Good morning. Thanks so much for the questions. Sure. I also have a question on powering assumptions for Energize Like Chris said, we know it's not apples to apples. Speaker 700:36:08But when you look at luspatercept, their mean hemoglobin increase was about 1.5 grams And they achieved I think around a 40% response rate on your primary endpoint. With this context, what are your internal expectations How many PIVOT will perform? And then I also have a follow-up. Speaker 300:36:28Thanks for the question. So in regards to our powering assumptions, we haven't spoken about these, but we have of course studied all of the programs in front of us, which includes Our own internal programs in which we took a very similar development approach for thalassemia as we have for PKD. In regards to the hemoglobin increase that you mentioned, so we don't from a transfusion dependent we don't believe you necessarily need to increase hemoglobin on top of making people reduce their transfusions. This is truly A different approach because people when they get transfused, their hemoglobin goes down over time. So what we are trying to do here is basically Avoiding that people their hemoglobin decreases back to a transfusion trigger, which then would trigger a transfusion. Speaker 300:37:19And it comes down again to that mechanism of action, if you are like stimulating out red blood cells, ultimately you're going to increase hemoglobin versus What we're trying to do about keeping the red blood cells happier and healthier thereby reducing hemolysis is a completely different way of trying to avoid transfusions. Speaker 700:37:42Thanks, Sarah. That's helpful. And that actually is a perfect segue for my follow-up. Do you have data on the potential of mitapivat for extending the half life of healthy red blood cells? Speaker 300:37:58So we in the context of you mean Health see volunteers red blood cells? Speaker 700:38:07Or like the eye extending the lifespan of transfused blood? Speaker 300:38:12So yes, so this is something that is extremely difficult to measure in the context of a transfusion setting as everything is kind of mixed. So it would require very, very unique experiment to be able to tease apart those types of red blood cells that are available. So we're not planning on doing that right now for our transfusion dependent patients. Speaker 700:38:40Got it. Thanks again for the questions. Operator00:38:44Thank you. And our next question comes from the line of Gregory Renza with RBC Capital Markets. Your line is now open. Speaker 500:38:53Hey, good morning, Brian and team. Congrats on all the progress and thanks for taking my questions. Brian, you certainly speak to the multibillion dollar opportunity available with PK activation and your portfolio. Just curious if you could maybe just elaborate a little bit on that, maybe provide some of the inputs or assumptions that you're using to get to that characteristic, whether it's with respect to mitapivit and the ramp of indications or the broader portfolio? And maybe I'll just layer in my second question, which With respect to the landscape in PK activation, perhaps, maybe Sarah can just riff a little bit about maybe the differences with mitapivant versus others, especially atavapivant, certainly you've mentioned the lead, you have the body of data. Speaker 500:39:39But when you think about some of the nuances on On pan PK activation or even selectivity, maybe just help us understand the differences between mitapivit and the landscape? Thanks so much. Speaker 200:39:53Yes. Thanks, Greg. So I'll get started on your first question about the multibillion dollar opportunity or opportunities that I referenced in my prepared comments. That really comes from the fact that we're rapidly progressing in our pipeline moving from clear ultra rare with PKD into successively larger prevalent diseases. Some of those diseases I think are well characterized in terms of opportunity sickle cell for sure where there's been a lot of interest and A lot of therapeutic development focus. Speaker 200:40:30And here we're talking about moving from 3000 to 8000 patients across The U. S. And EU5 in the case of PKD jumping to just in the U. S. Alone 100,000 patients with sickle cell disease. Speaker 200:40:44But it's more than that. I mean, as we've already discussed this morning, we had this really exciting opportunity Relatively near term with a potential launch next year in thalassemia, which is a prevalence step up in the case of the U. S. From PKD sickle cell I just mentioned and then even after that with our other PK activator AG946 moving into low risk MDS. The great news about all this is we're moving in the right direction in terms of prevalence and that is allowing us to enter into very commercial opportunities. Speaker 200:41:23And it also allows us to navigate through the appropriate pricing dynamics as we go forward. But we are very excited Most importantly with the fact that as we advance our pipeline and as we've already noted, we have 2 back to back launch potentials with thalassemia next year followed by sickle cell disease in 2026. And then Sarah, you want to pick up for the next question? Speaker 300:41:47Sure. So in regards to PK activation and The differences between misopivat and some other PK activators. So we indeed while we stimulate PK, Different PK isoenzymes amongst which the PKR, which is important for the red blood cell, but then also PKM-two is important. Then we understand more and more The relevance of this specific isoenzyme in the context of the diseases that we are studying. As you know, Thalassemia, sickle cell disease, MDS, there is different components to these diseases in which stimulation of PKM2 may be relevant As it is expressed in immature red blood cells, it is expressed in other tissues that are also touched by these diseases. Speaker 300:42:40We are planning to further study this clinically as well, specifically in sickle cell disease In the kidney, as we know, kidney is such an important organ in the context of sickle cell disease and that many patients suffer from kidney disease and we believe that PKM2 may have an added advantage there. In regards to how that compares to other PK activator specifically as a propofab that is they this is the drug that used to be form a drug. They always spoke about being a PKR selective agent in regards to how they translate into other isoenzymes, they have not spoken about that. They have just highlighted their selectivity message. Operator00:43:29Thank you. Our next question comes from the line of Salveen Richter with Goldman Sachs. Your line is now open. Speaker 800:43:37Hi, this is Lydia on for Salveen. Thanks so much for taking our question. Just one on sickle cell, could you just discuss where you see ThyroKline fitting into the current commercial landscape just broadly. And then can you also speak to the commercial or the enrollment progression and any physician feedback you've gotten so far? Thanks so much. Speaker 200:43:55Sure. And maybe I will just start and then quickly turn it over to Sveta and then Sarah can pick up on The enrollment aspects, I mean, the fundamental premise of what we're driving towards with sickle cell disease is we believe that mitapivatpirakine has the potential to be what we refer to as foundational therapy. This is A very different mechanism of action as we've talked about, very unique from currently available options. We're increasingly Convinced that the benefits on making the red blood cells healthier really position it as such. And then the fact that this is an oral treatment only adds to that potential. Speaker 200:44:39But I'll let Sveta speak a little bit more about Not just how we're thinking about sickle cell disease, but the bridge as we go from PKD to thalassemia and then to sickle cell. Speaker 400:44:51Thanks, Brian. I'll start with sickle cell disease first, but as you said, we have a very important milestone with the thalassemia launch ahead of that, which we believe will be an important point from growing the commercial capabilities, executing on launch and after that capitalizing on sickle cell disease. When we think about sickle cell disease, Brian mentioned that and Sarah mentioned that already, The prevalence of the disease is 100,000 patients in the U. S, which is a significant step up from where we are today with PK deficiency. It's a disease where patients are diagnosed and the burden of disease is well characterized. Speaker 400:45:31At the moment, the outpatient population with sickle cell disease has very limited treatment options available. They are either improving hemoglobin levels, which is a case of a brighter, For improving VOCs based on the Phase II data and the target product profile we have for Firoquant for launch, We believe that we'll be very well positioned with Biokind to provide a treatment option which will bring benefits to Physicians, patients and ultimately payers as well by improving hemoglobin, reducing doses and ultimately improving the way patients feel and function and that's going to be a unique value proposition if we were to deliver on that profile. So we are very excited about that opportunity to come. But before we get to sickle cell disease, we are We're very excited to progress with our launch preparation for thalassemia as well. After we saw the results from the energized data in the year, we have definitely pressed the button and are actively preparing for a thalassemia launch to come in 2025. Speaker 400:46:44Similar to sickle cell disease, I think the thalassemia launch will be meaningfully differentiated in terms of market characteristics that compared to PKD And that will position us well for adoption of Firohind assuming approval in 2025, including again these patients are diagnosed, it's 6,000 diagnosed patients in the U. S. With thalassemia, well established ICD-ten cones, a stronger of the prescriber base and all of these elements gives us confidence on our ability to commercialize the product and drive adoption at launch. And similar to sickle cell disease, there is a better understanding of the thalassemia unmet needs across both the transfusion dependent but also the non transfusion dependent patients as well. So we are gearing up and getting ready to commercial organization launch in TELUSIMI in 2025 potentially followed by ZECTROBET launches in sickle cell disease in 2026. Speaker 200:47:46I was just going to say that's great, Sada. And I think everybody can sense our excitement about we have in front of us and I was just going to ask Sarah to make a comment about the progress with RISE UP Phase 3 for sickle cell. Speaker 300:47:57Exactly, because we're Equally excited to move towards those launches. So we are heavily focused on our Phase 3 enrollment, of course, right now. The trial is progressing as we are anticipating. There's a lot of enthusiasm both within our teams and of course on the by the investigators as well. And so everything is on track to deliver to the milestone that we have set out for this year. Operator00:48:24Thank you so much. Thank you. Speaker 200:48:26Thank you. Operator00:48:27Our next question comes from the line of Tess Romero with JPMorgan. Your line is now open. Speaker 900:48:36Great. Good morning, Brian and team. Thank you for taking our question. So switching gears a little bit to commercial PKD. Do you still think that PKD could be a $200,000,000 to $250,000,000 peak opportunity here in the U. Speaker 900:48:52S? And if so, how long do you think it could take you to get there? And then my second question is, We know that you're moving AG-nine forty six forward in lower risk MDS, but we were curious, have you Formally deprioritized the program in sickle cell disease as we hadn't heard anything on this in a while. Can you confirm if that's the case or not? Thanks so much for taking our questions. Speaker 200:49:22Thanks a lot, Tess. Actually the second question, we can handle that very quickly, which is No. And we have not deprioritized anything with AG-nine forty six. I think we're inspired by the potential. And at the right time, we'll provide updates about the progress, not just in our pursuits of low risk MDS, but also where we stand with respect to sickle cell disease. Speaker 200:49:46Cecilia, do you want to comment on the first one? Operator00:49:48Yes, sure. Speaker 400:49:48Thanks for the question. So we definitely remain excited about the opportunity PKD and we continue to expect those peak sales at $200,000,000 to $225,000,000 for the U. S. We continue to make progress each quarter and we're learning and as far as that, this is also based on capabilities for that launch. We think it's going to be slow and steady continuing to see the trends we've seen in 2020 3 for the next few years, but we do still maintain our peak of 200 to 225. Speaker 200:50:18Yes. I mean, with PKD We've talked about this previously, but in the deep commercial experience that both Sveta and I have across multiple Rare disease launches. This one's tough. It's a challenge. It is ultra rare. Speaker 200:50:33It's diagnostically intensive. There's long lead times for patients. So slow and steady is the right phrase. What we're continue to be inspired by each quarter is that persistency, which is something we saw relatively early with the launch of pyrokinin PKD. That is a really important feature as we think about chronic rare disease launches to come that are in our sites. Speaker 200:51:01And so we'll take the slow and steady path and we're going to continue to expect that going forward. But the way Pirate Kind is performing is what We believe really puts us in a position of strength as we approach energize sorry, I keep saying energize as we approach thalassemia as well as sickle cell beyond that. Speaker 900:51:24Okay. Thanks so much for taking our questions. Speaker 200:51:27You bet, Teth. Thanks a lot. Operator00:51:29Thank you. Our next question comes from the line of Greg Harrison with Bank of America. Your line is now Speaker 500:51:34open. Hey, good morning. Thanks for taking the question. Also just wanted to follow-up on AGN-nine forty six. How are you thinking just generally in development about development and potentially overlapping indications With mitapavat, if there could be improvement, for example, in sickle cell, like you discussed or even thalassemia? Speaker 500:52:03And what would you need to see from 946 in order to make that decision? Speaker 200:52:09Yes. I'll start and then Sarah can jump in. 1st of all, Greg, I hope we're in that position where we have multiple indications just as we have Right now with Thyrokine, one of the key advantages of at Agios of having really a leading PK activation franchises, we have not one, but 2 products that we're developing. And that allows us to have different economics, different pricing dynamics across the indications in between the products. I think there's a wide enough space for us right now given where we are in the development program with AG-nine forty six that we can tailor the appropriate target product profiles whether it's for sickle cell disease or for low risk MDS. Speaker 200:52:57In the case of low risk MDS, As I think folks know, we just reported out last year very encouraging Proof of concept from our Phase 2a study and we're in the process right now of making enhancements in the design so we can pursue Phase to be I feel very good about the work the team has done and that'll be the next step. And as I mentioned before, at the right time, we'll also report out the progress on sickle cell disease. Anything you want to add, Sarah? Speaker 300:53:28Just high level, I think what you can expect from development is that we always try to design our trials To meet multiple stakeholders, their needs, meaning we take our target product profile very seriously. So that is something That for 946 is the same. We take that very seriously and we incorporate we will be incorporating patient voice and the regulatory feedback obviously as well. Speaker 200:53:55Yes. And a great example of that is in the case of sickle cell disease, a point that we're very proud of that Agios is we have deeply involved the community. And in fact, Sarah and I attended the conference last year where we won an award from the community about How carefully and thoughtfully we involved sickle cell disease warriors and caregivers in how we think about designing the trials, recruiting for the trials and ultimately what the commercial profile should look like. And we'll do the same thing with AG-nine forty six. Speaker 500:54:30Great. Thanks for taking the question. Speaker 200:54:32You bet, Frank. Thanks. Operator00:54:33Thank you. And our last question will come from the line of Divya Rao with TD Cowen. Your line is now open. Speaker 1000:54:43Hi, guys. This is Divya on for Mark. I have 2 kind of follow-up questions. 1 on Eric's question earlier, Was the difference in the primary endpoint between mitapivat and luspatercept for the transfusion dependent patient something that was recommended to you by regulatory authorities or was it more of an internal choice? And then my second question is turning to the design of the Phase 2b in MDS. Speaker 1000:55:10Do you plan to test multiple dose levels of AG-nine forty six? And any color on the enrollment criteria versus what Reposil had in the KOMAMMZ trial would be great. Thank you. Speaker 300:55:22Awesome. Thank you. Thanks, Divya. So in regards to the first question, primary endpoint, yes, indeed, we do as I just mentioned on the previous question as well, we do Our development in collaboration with regulators, so we take feedback from the regulators very seriously and try to really incorporate the feedback as best as we can. And so that's how we ended up settling for the 50% endpoints in a rolling 12 week period interval, which we indeed truly is a more dynamic endpoint and really reflects the real world experience of a patient. Speaker 300:56:02So this is where it's always very good And we're always very grateful to be able to have those conversations because I do think incorporating feedback from multiple stakeholders always leads to better design choices. So that's that on the primary endpoint. And then in regards to your question for MDS Phase IIb, yes, the Phase IIb is indeed multiple doses that we are testing. We are going to test higher doses than we originally anticipated just Because we have learned from our Phase IIa that MDS patients overall have lower exposure to Same amounts of drug than other patient populations and healthy volunteers. So we are incorporating those learnings into our Phase IIb. Speaker 300:56:57And in regards to our inclusion criteria, we have not We haven't presented a trial in progress post or anything like that yet, but you can expect the population to be Relatively similar to how our population was in the Phase IIa. However, we will be focusing on transfusion patients with transfusion burden. It will also be a broad MDS population just like we allowed in the 2a. We're not excluding per se a population like Operator00:57:37Thank you. I would now like to hand the conference back over to Mr. Brian Gough for closing remarks. Speaker 200:57:44All right. Thanks a lot, Norma. And thank you very much everyone for participating in today's call. Very good questions, which we very much appreciate. As you heard today, our team has great conviction in our potential to deliver transformative new therapies to patients and significant long term value to shareholders. Speaker 200:58:04And we really look forward to speaking with all of you again soon. So thanks a lot.Read morePowered by Conference Call Audio Live Call not available Earnings Conference CallAgios Pharmaceuticals Q4 202300:00 / 00:00Speed:1x1.25x1.5x2x Earnings DocumentsSlide DeckPress Release(8-K)Annual report(10-K) Agios Pharmaceuticals Earnings HeadlinesAgios Pharmaceuticals, Inc.

There are 11 speakers on the call. Operator00:00:00Good morning, and welcome to Agios' 4th Quarter 2023 Conference Call. At this time, all participants are in a listen only mode. There will be a question and answer session at the end. Please be advised that this call is being recorded at Agios' request. I would now like to turn the call over to Chris Taylor, Vice President, Investor Relations and Corporate Communications for Agios. Operator00:00:20Please go ahead. Speaker 100:00:24Thank you, operator. Good morning, everyone, and welcome to Agios' conference call and webcast to discuss 4th quarter and full year 2023 Financial Results and Recent Business Highlights. You can access slides for today's call by going to the Investors section of our website, agios.com. On today's call, I'm joined by our Chief Executive Officer, Brian Goff Doctor. Sarah Hewins, Chief Medical Officer and Head of Research and Development Sveta Milanova, our Chief Commercial Officer and Cecilia Jones, Chief Financial Officer. Speaker 100:01:02Before we get started, I would like to remind everyone that some of the statements we make on this call will include forward looking statements. Actual events and results could differ materially from those expressed or implied by any forward looking statements as a result of various risks, uncertainties and other factors, including those set forth in our most recent filings with the SEC and any other future filings that we may make with the SEC. With that, I'll turn the call over to Brian. Speaker 200:01:30Thanks, Chris, and good morning, everyone, and thank you joining us. Our mission at Agios is to develop and deliver transformative medicines that elevate and extend the lives of patients living with rare diseases. Driven by this goal, we continue to generate consistent and compelling data across our industry leading PK activator franchise. And with seamless cross functional collaboration of the Agios team, we made remarkable progress advancing this mission in 2023. Highlighting this progress, we reported 3 key data readouts in the last 12 months. Speaker 200:02:09In June, we reported positive top line data from the Phase 2 portion of the RISE UP study of mitapivat, our lead PK activator in sickle cell disease followed by the full data set in December at ASH. Despite the field's recent progress in sickle cell disease, there are no novel oral therapies that both improve anemia and reduce sickle cell pain crises and that is precisely what we aim to deliver with mitapivat. In November, we reported positive data from the open label Phase 2a study of our other PK activator AG-nine forty six in lower risk MDS with 40% of patients achieving the transfusion independence endpoint. And just last month, we reported positive data from the Phase 3 Energize study of mitapivat in non transfusion dependent thalassemia. As a reminder, non transfusion dependent or NTD thalassemia accounts for approximately 2 thirds of thalassemia in the U. Speaker 200:03:14S. And has no FDA approved treatment option. Despite not requiring regular transfusions, NTD thalassemia patients experienced significant impact on quality of life, a wide range of serious morbidities and an elevated risk of premature death. Together, the consistency of data generated across the mitapivat development program bolsters our conviction in the probability of success of our ongoing studies, including 2 additional Phase 3 readouts we expect by the end of this year. And this data highlights the potential of our PK activators to transform the course of multiple hematologic diseases. Speaker 200:03:59Sarah will provide more detail on our advancements and upcoming milestones across our pipeline in just a few minutes. Importantly, we believe our PK activation pipeline is well positioned with multiple near term catalysts to become a multi $1,000,000,000 franchise and deliver significant value. In parallel with advancing the late stage mitapivat development program across multiple indications, our commercial organization is laser focused on building the infrastructure established through our current launch in PK deficiency to prepare for potential U. S. Launches of mitapivat in thalassemia in in 20 25 and in sickle cell disease in 2026. Speaker 200:04:45Sveta will provide greater detail on the commercial opportunities for mitapivat in thalassemia as well as an update on our current launch in PK deficiency in just a bit. Finally, as you'll hear from Cecilia, we ended 2023 with a strong cash position with approximately 806 $1,000,000 in cash and investments on the balance sheet. In addition, we continue to track Servier's progress towards the potential FDA approval of vorasidenib given our retained economics for both the milestone and royalties. This is truly an exciting time at Agios with 4 additional Phase 3 readouts and 2 potential launches expected on the horizon. We look forward to multiple opportunities to drive significant near term value creation for patients, caregivers and shareholders. Speaker 200:05:40With that, I'll now turn the call over to Sarah. Speaker 300:05:44Thanks, Brian. In 2023, our research and development organization made tremendous progress advancing our PK activator development program. Led by Metopimab, the industry's most advanced PK activator now with over 8 years of clinical experience, the consistent and compelling data we have generated to date in PK deficiency, Thalassemia and sickle cell disease continue to derisk our ongoing development program and highlight for this molecule to transform patient's function and quality of life. We are also enthusiastic about the potential Operator00:06:24for the rest of our growing pipeline, Speaker 300:06:24and we are pleased to note that we remain on track to deliver on our milestones, including enrolling the first patients in the Phase IIb trial for AG-nine forty six in lower risk MDS and for the Phase I trial for HE181, the compound name for our PAH stabilizer for phenylketonuria. Reading out top line data for the Phase III ACTIVATE KITs P study in regularly transfused pediatric patients with PK deficiency and completing enrollment of the Phase 3 ACTIVATE KIT study in pediatric patients with CKD. Turning to sickle cell disease, we were pleased to present detailed positive results from the Phase 2 portion of the Phase 2, III RISE UP study of mitapivat at ASH in December. The study achieved its primary endpoint of hemoglobin response And in addition, an improvement in annualized rates of sickle cell pain crisis was observed. And we have been delighted by the enthusiasm of the investigators. Speaker 300:07:25We continue to advance enrollment in the Phase 3 portion of this study and remain on track to complete enrollment by the end of this year. While the treatment landscape in sickle cell disease continues to evolve, there remains an urgent and unmet need for convenient novel oral treatment options that address both anemia and sickle cell pain crises. And we believe firmly in the top of our potential to deliver a best in class option for patients from this devastating disease. And finally, on thalassemia, I'll take a moment to highlight a few key elements of our program and the positive top line Phase 3 data we reported last month in non transfusion dependent thalassemia. As a reminder, the Phase 3 program of spirokinin thalassemia and compacting 2 Phase 3 randomized placebo controlled trials was designed to deliver data across all populations of thalassemia, such as alpha and beta thalassemia and populations with different transfusion needs. Speaker 300:08:26Both trials enrolled patients with alpha or beta thalassemia, but enrolled different populations as it relates to transfusion needs. We want to highlight that Energize is the 1st clinical program that included patients who were not regularly transfused and alpha thalassemia patients. As Brian mentioned, there are no FDA approved treatments for non transfusion dependent thalassemia, which represents approximately 2 thirds of total thalassemia patients in the U. S. These patients suffer from a poor quality of life, a high rate of serious morbidities, including thrombosis and premature death. Speaker 300:09:02We were therefore very pleased to be able to announce positive results from the Energize study. As a reminder, the Energize enrolled a total of 194 patients with either alpha or beta non transfusion dependent thalassemia, randomized 2:one to 100 milligrams nizapagat placebo twice daily. The speed of enrollment and the actual number of patients enrolled in the study as well as the high completion and rollover rate supports the idea that people who are not regularly transfused were motivated to take action and speaks to the unmet need for this population. The primary endpoint of this study was hemoglobin response rate defined as an increase of at least 1 gram per leader in average hemoglobin concentration from week 12 to week 24 compared to baseline. The key secondary endpoints of the were changed from baseline in average rapid fatigue score and changed from baseline in average hemoglobin concentration, also both assessed from week 12 to 24. Speaker 300:10:02On the primary endpoint, treatment with mitapivat demonstrated a highly statistically significant result with 42.3% of patients in the treatment arm achieving a hemoglobin response versus 1.6% of patients in the placebo arm. In line with mitapivax novel mechanism of action, which focuses on overall red blood cell health and the data generated with mitapivax across additional disease areas, the beneficial effects of mitapifat in this study extended beyond hemoglobin alone. Specifically, treatment with 100 milligrams mitapifat resulted in statistically significant improvements in both key secondary endpoints, including a change from baseline in average facet fatigue score, an important patient reported measure of how patients feel and function. Importantly, across the primary and secondary endpoints, All pre specified subgroup analyses favored nipativat compared to placebo, suggesting that no single subgroup was responsible for driving the results, which supports our plan to file for a broad label covering all thalassemia subtypes. This is therefore the first drug that not only improves hemoglobin, but actually makes people with thalassemia feel better, consistent with what we observe in patients with PKD and what we hope to be able to deliver for patients with sickle cell disease as Complementing the near term benefit of thalassemia patients reporting that they had less fatigue and felt better in the near term, Clinicians in the trial and other KOLs appreciate the potential longer term benefits of reducing markers of hemolysis and the longer term potential to reduce serious morbidities. Speaker 300:11:43We are very much looking forward to presenting the full data set at a medical meeting. Beyond the excitement we have for the ENERGISE data itself, the readout of the ENERGISE trial also gives us further confidence towards the readout of ENERGISE Thalassemia is a hemolytic anemia irrespective of whether a patient is in need of transfusions or not. In addition, the mechanism of action of mitapivat is not dependent on the need for transfusions. We have already demonstrated an improvement in hemolytic anemia in the ENERGiSE trial with a positive change in hemoglobin. We are now waiting to see if the improvement in hemolytic anemia can also be documented via a reduction in transfusions in Energize T. Speaker 300:12:28As a reminder, the primary endpoint of Energize is transfusion reduction response defined as a 50% or greater reduction in transfused red blood cell units with a reduction of equal or more than 2 units of transfusion dependent allopathy in any consecutive 12 week period through week 48 compared to the baseline. Like the ENERGISE study in non transfusion dependent allassemia, the design of the ENERGISE E trial enables us to demonstrate clinical meaningfulness in a variety of ways via reduction in transfusion burden, which also includes transfusion metrics in line with that other studies have used. We designed this study incorporating learnings from prior studies and agency feedback and believe a dynamic assessment period is important as patients aren't We look forward to the readout of this study by mid year and plan a single regulatory filing to the FDA encompassing data from both Energize and Energize P by the end of this year, seeking a label that will enable people living with thalassemia access a convenient and differentiated oral treatment option. Overall, I'm very proud of the tremendous progress made by our R and D organization in 2023 and look forward to continuing this momentum in 2024. Speaker 400:13:43With that, I will now turn the call over to Sara. Thanks, Sarah. Celotemia remains an area of higher met need with few treatment options. The burden of disease on the patients is significant regardless of their transfusion needs. Thalassemia patients experience increased mortality compared to the general population and can be significantly worse in non regularly transfused than those who are regularly transfused. Speaker 400:14:17Patients endure high rates of morbidities and increase complications as they age. Adult patients with non transfusion dependent thalassemia may actually have similar or worse quality of life compared to transfusion dependent patients. Of course, this burden of disease correlates to increased health care costs. To address this unmet need and galvanized by the positive data from the Phase III energized study of mitapylak, Our commercial organization is actively preparing for a potential launch in Telotenia next year, beginning with the U. S. Speaker 400:15:04In the U. S, there are approximately 6,000 diagnosed adult patients with thalassemia. Approximately 4,000 of these patients are non transfusion dependent and have no available treatment options today. The remaining 2,000 patients are transfusion dependent and have no oral treatment option. Our goal with mitapivax is to address the nonmet need of all adults living with thalassemia and become the 1st therapy approved for all the types of the disease. Speaker 400:15:47In addition to the data we are generating through the mitapivac clinical development program, there are 3 key factors we believe have the potential to support adoption of mitapiva among thalassemia patients in the U. S. First, there is strong alignment between where in the U. S. These patients reside and where they receive treatment. Speaker 400:16:13The map on Slide 20 depicts patient prevalence Overlaid with the Agios clinical trial sites and or centers of excellence represented by the gold stars. 2nd, the diagnosis rate is high, driven by availability of newborn screening and well established ICD-ten codes, many patients are diagnosed before adulthood. And finally, as shown on Slide 21, There is concentration of patients and providers at selected centers. Approximately 50% of all diagnosed patients are treated as fewer than 150 affiliated hematology oncology practices in the U. S, providing a clear focus for our initial launch. Speaker 400:17:07Given this market dynamic and ThyroKymes target product profile, we believe we are well positioned to provide a potential foundational treatment options for patients with thalassemia regardless of subtype. Therefore, our team is focused on 4 core areas of U. S. Launch preparation. 1st, building on the foundational work we have already done, We continue to deepen the sophistication of our market understanding. Speaker 400:17:39We are conducting extensive market research and claims data analysis to inform ATP targeting, field force sizing and deployment for launch. 2nd, we'll be rolling out a disease education campaign for both patients and clinicians, highlighting the long term complications and burden of disease across all thalassemia subtypes. Our disease education engagement will also work to correct the historical misperception that non transfusion dependent patients are less likely to experience the debilitating long term effects of thalassemia. To support these initiatives, we are establishing capabilities to enable execution of our educational efforts across personal and non personal channels. 3rd, we will continue to strengthen our commercial capabilities by expanding our sales team in anticipation of the thalassemia launch, rightsizing the team for a broader rare disease. Speaker 400:18:46And lastly, in parallel with those efforts, we are preparing our market access team to engage with payers on disease safety education in advance of the potential launch in thalassemia next year. Our team has obtained in market access for PGA deficiency, and we look forward to watching them pave the way in Telestinia, too. In addition to the well established U. S. And Lathemian market, there are approximately 13,000 patients in the EU5 and approximately 70,000 saluthenia patients in the Gulf region. Speaker 400:19:25We aim to maximize the potential of these additional markets through coordinated regulatory filings, which we intend to pursue with partners. Taken together, we believe the potential launch of mitotivat in thalassemia represents a significant opportunity for Agios and a step forward as we prepare for potential back to back launches with sickle cell disease in 2023. Now let me provide an update On the current launch of PyroKyne in PK deficiency. In the Q4 of 2023, we generated $7,100,000 in net Biopharma revenue compared to $7,400,000 in the prior quarter. A total Of 178 patients have completed a prescription enrollment form including 18 in the Q4 of 2023, an 11% increase versus the 3rd quarter. Speaker 400:20:29This translated into net 109 patients on therapy, a 9% increase versus the 3rd quarter. Patients on therapy continue to stem from a growing and diverse prescriber base of 154 physicians and represent a broader demographic and disease manifestation range that is consistent with the adult PK deficiency population. We continue to be encouraged by the persistency of patients on treatment and remain focused on efficiently identifying providers likely to treat patients with PK deficiency. The capabilities we continue to build and expand through the current launch, including Efficient targeting analytics, patient awareness and education and patient access will provide a firm foundation from which we can maximize the potential U. S. Speaker 400:21:27Launches in telatinia in 2025 and in sickle cell disease in 2026. As we advance through this catalyst rich period A Phase 3 data readout for mitapivat, we look forward to dramatically expanding the number of patients we serve. With that, I'll turn the call over to Cecilia. Thanks, Veda. Our Q4 2023 financial results can be found in the press release we issued this morning and more detail will be included in our 10 ks, which will be filed later today. Speaker 400:22:05Let me now take a moment to provide some context and highlight a few key points. Full year 2023 net Pyrocant revenue was 26 $800,000 compared with $11,700,000 in firecrane revenue for 2022. Q4 2020 City net Pyrocant revenue was $7,100,000 a 4% reduction compared to the 3rd quarter. The reduction was driven by lower number of weeks on hand of inventory compared to where we ended Q3, partially offset by favorability in As a reminder, we anticipate low levels of inventory at any given time given our limited distribution network, which consists of 1 specialty pharmacy and 1 specialty distributor. Consistent with other rare disease launches, growth to net is to be in the 10% to 20% range on an annual basis. Speaker 400:23:02Based on our learnings to date, Given the ultra rare nature of the disease and the long lead times associated with initiating patients on therapy, we continue to expect slow and steady growth and quarter to quarter variability in 2024, similar to what we saw in 2023. Cost of sales for the Q4 was 0.6 $1,000,000 R and D expenses were $77,000,000 for the 4th quarter 296 $1,000,000 for the full year 2023, an increase of $16,000,000 compared to the full year 2022. These changes reflect an increase in development costs for mitapivat and the upfront payments associated with the license agreement with Alnylam, offset by a reduction in expenses associated with the evolution of our research organization and the sale of our oncology business to Servius. SG and A expenses were $35,000,000 for the 4th quarter and $120,000,000 for the full year 2023, a decrease of $2,000,000 compared to the full year 2022. As a reminder, as part of the divestiture of our oncology business to Servier, We retain rights to a potential $200,000,000 milestone upon FDA approval of rasitanib and 15% royalties on potential U. Speaker 400:24:26S. Net Servier publicly communicated plans to file for approval before the end of 2023, so we are eager to track their progress. We ended the year with cash, cash equivalents and marketable securities of approximately $806,000,000 We expect that this balance together with anticipated product revenue, interest income and the potential vorasidenib milestone would enable the company to fund our operating expenses and capital expenditures through several value creating milestones and at least into 2026. This guidance does not include cash inflows that could extend the runway beyond 2026, including the potential royalties from ruxidinib, commercializing Mitepivat outside of the U. S. Speaker 400:25:16Through 1 or more partnerships or other potential strategic business or financial agreements. We remain focused on creating shareholder value, including by proactively managing our cost base and deploying a disciplined cash allocation approach As we prepare to support potential future launches of Paragon, as we move toward additional potential value creating milestones in the near term, I am confident that our strong balance sheet will enable us to execute from a position of strength as we continue to pursue ways to create shareholder value. I will now turn the call back over to Brian for his closing remarks. Speaker 200:25:53Thanks, Cecilia. As we turn the page on a highly productive 2023, We're focused on executing across the additional 4 Phase 3 readouts for mitapivat that we expect over the next 2 years, Beginning with the Phase 3 Energize T study in transfusion dependent thalassemia in the middle of this year. As we continue to stack successive positive data readouts for mitapivat, we are only growing more confident in the probability of success ahead. We're well positioned with a differentiated mechanism of action that improves red blood cell health beyond hemoglobin increase and allows us to pursue large commercial opportunities with substantial value and the potential for 2 additional first in class and best in class indications for pyracine as we build a multi $1,000,000,000 franchise in PK activation. As we continue to take steps toward realizing our vision of becoming a leading rare disease company, We will continue to strive to be responsible stewards of our balance sheet and evaluate meaningful opportunities for value creation. Speaker 200:27:08Finally, I'd like to thank all of our employees for their hard work and dedication to our mission of developing and delivering transformative medicines that elevate and extend the lives of patients living with rare diseases and all of our partners, including the patients, physicians, caregivers and participants in our clinical development programs. With that, we will now open the call for questions. Operator00:27:36Thank Our first question comes from the line of Eric Schmidt with Cantor Fitzgerald. Your line is now open. Speaker 500:28:12Well, thanks for the question and congrats on all the recent development I guess maybe one for Sarah, given the next milestone, next T milestone at least might be the Energized T study for mitapivant in Can you give us a little bit of a preview here or set up with regard to the primary endpoint? I know you're looking at transfusion reductions in a slightly different way than what we've been accustomed to seeing with the luspatercept data. So How might that primary endpoint definition change the way we view the data and what might the hurdle be? Speaker 200:28:49Great. Eric, thanks a lot for the question. And I just before Sarah goes, I just want to welcome you back to Agios earnings call. So Sarah, do you want to get started? Speaker 300:28:59Sure. Thanks for the question. So indeed, our endpoint, our primary endpoint has a different definition than the primary endpoint that was TATA Septu use in the sense that we are looking at a 50% reduction in any 12 week period rolling period basically over the 48 weeks that patients are assessed, which we believe is a more appropriate measure to assess a patient in the context of a dynamic disease over a longer stretch of time and which reflects better the real world experience that patients may have. We do have a similar endpoint like the luspatercept primary endpoint in our secondary endpoints. In regarding to the hurdles, It is a different endpoint indeed. Speaker 300:29:44The hurdle is not necessarily different in the sense that you have multiple assessment periods versus a fixed period in time. The bar of 50% of course is higher than 33%. But like I said, because it's every any 12 week period you have more shots on goal as to speak. This was an endpoint that luspatercept also had in their assessment and in their review, but as it was not a pre like primary or secondary analysis that did not make it into the label. Speaker 500:30:16Thank you very much. Thank you. Operator00:30:21Thank you. One moment for our next question please. Our next question comes from the line of Chris Raymond with Piper Sandler, your line is now open. Speaker 600:30:38Thanks. Maybe just a question on the Energize data that we got last month. We've gotten a few questions around from investors around the sort of the transition from the Phase 2 data to the Phase 3 data. There was a degradation in the hemoglobin response, but you measured these effects over different time points. I know you guys had said that there was no waning of efficacy over time, but maybe just square this difference that you saw? Speaker 600:31:07And then I've got a follow-up. Speaker 300:31:10Sure. Thanks for the question. So the primary endpoint that we used in a Phase 2 was indeed different than the endpoint that we used in the Phase 3, meaning that for the Phase 2, we just looked at patients meeting a hemoglobin response at a single time point. And for the Phase 3, we incorporated the duration in that endpoint over a longer stretch of time and measured at a later time point because it's a chronic disease. So then from a Phase 2 perspective, you're truly looking for maintenance over a longer duration of time. Speaker 300:31:45So we averaged hemoglobin over 12 weeks versus that just single time point, which is much easier to reach as a bar. In regards to the waning, we don't see waning of our hemoglobin response. So mitapivat in this trial behaves very similarly to how it behaves in PKD. So once patients show a response, they tend to maintain that response over time. There's always a little bit of fluctuation on the hemoglobin over time, but overall it stays positive and the line kind of stays horizontal in comparison to their baseline. Speaker 300:32:22So we feel very confident with the results that we have observed in Energize. In addition, it's more than hemoglobin alone that we observed. We really saw an improvement on the facet fatigue there as well, which we believe is extremely meaningful because Now we are adding to the hemoglobin plus story here. The things that we've observed in PKD now also have been observed in the non transfusion dependent population and that continues to add to this consistent and compelling data story that we are continuing to generate. Speaker 600:32:54Okay, thanks. And then maybe just a follow-up to Eric's question on the success bogey of Energize Tea. I know it's you're talking about different measures. It's not an apples to apples comparison to luspatercept. But Just as you're thinking about the obvious difference, admitted to that is oral versus luspatercept, which is not. Speaker 600:33:19Just maybe talk in generalities how you see these 2 compounds sort of coexisting commercially? Speaker 300:33:27Sure. So if we think about the non transfusion dependent thalassemia patient population, they currently have no therapy available. So that is Mitakova would if we get it through the next stages of development would be the therapy that it would The available for non transfusion dependent patient populations and is oral indeed, which is a huge benefit specifically for that population because patients aren't Going to clinic as frequently and if you have a drug that requires frequent clinic visits that adds to the burden of disease typically. For the transfusion dependent patient population, there is indeed subcutaneous Luspatercept available for transfusion dependent beta thalassemia patients, our program has studied All genotypes of thalassemia, so that's one difference. The oral route of administration here is very relevant because it allows for almost a seamless incorporation into a transfusion schedule that a patient may have versus requiring more visits on top of the transfusion schedule. Speaker 300:34:40In that sense, it's also important to understand there's a very different mechanism of action between those 2 products, which is a stimulator, red blood cell stimulator, while mitapivat It's trying to improve red blood cell health overall and so we do think from that perspective, they're vastly different. Speaker 200:35:02Yes. And Chris, I mean that last point is the one that I would just emphasize is that I know folks are trying to make comparisons, but in so many ways they're incomparable of the profound difference in the mechanisms and you'll hear a lot from us because we continue to be emboldened by this by the data that we see very consistently that the benefits of pyruvate kinase activation really do go beyond hemoglobin. So we'll await the data. Fortunately, we don't have to wait that long. Energize Tea is coming mid year. Speaker 200:35:35But I think above oral and the other dimensions, hemoglobin and the like, That's really the big headline for this mechanism is it's ultimately about red blood cell health. Operator00:35:46Thank you. One moment for our next question. Our next question comes from the line of Danielle Brill with Raymond James. Your line is now open. Speaker 700:35:56Hi, guys. Good morning. Thanks so much for the questions. Sure. I also have a question on powering assumptions for Energize Like Chris said, we know it's not apples to apples. Speaker 700:36:08But when you look at luspatercept, their mean hemoglobin increase was about 1.5 grams And they achieved I think around a 40% response rate on your primary endpoint. With this context, what are your internal expectations How many PIVOT will perform? And then I also have a follow-up. Speaker 300:36:28Thanks for the question. So in regards to our powering assumptions, we haven't spoken about these, but we have of course studied all of the programs in front of us, which includes Our own internal programs in which we took a very similar development approach for thalassemia as we have for PKD. In regards to the hemoglobin increase that you mentioned, so we don't from a transfusion dependent we don't believe you necessarily need to increase hemoglobin on top of making people reduce their transfusions. This is truly A different approach because people when they get transfused, their hemoglobin goes down over time. So what we are trying to do here is basically Avoiding that people their hemoglobin decreases back to a transfusion trigger, which then would trigger a transfusion. Speaker 300:37:19And it comes down again to that mechanism of action, if you are like stimulating out red blood cells, ultimately you're going to increase hemoglobin versus What we're trying to do about keeping the red blood cells happier and healthier thereby reducing hemolysis is a completely different way of trying to avoid transfusions. Speaker 700:37:42Thanks, Sarah. That's helpful. And that actually is a perfect segue for my follow-up. Do you have data on the potential of mitapivat for extending the half life of healthy red blood cells? Speaker 300:37:58So we in the context of you mean Health see volunteers red blood cells? Speaker 700:38:07Or like the eye extending the lifespan of transfused blood? Speaker 300:38:12So yes, so this is something that is extremely difficult to measure in the context of a transfusion setting as everything is kind of mixed. So it would require very, very unique experiment to be able to tease apart those types of red blood cells that are available. So we're not planning on doing that right now for our transfusion dependent patients. Speaker 700:38:40Got it. Thanks again for the questions. Operator00:38:44Thank you. And our next question comes from the line of Gregory Renza with RBC Capital Markets. Your line is now open. Speaker 500:38:53Hey, good morning, Brian and team. Congrats on all the progress and thanks for taking my questions. Brian, you certainly speak to the multibillion dollar opportunity available with PK activation and your portfolio. Just curious if you could maybe just elaborate a little bit on that, maybe provide some of the inputs or assumptions that you're using to get to that characteristic, whether it's with respect to mitapivit and the ramp of indications or the broader portfolio? And maybe I'll just layer in my second question, which With respect to the landscape in PK activation, perhaps, maybe Sarah can just riff a little bit about maybe the differences with mitapivant versus others, especially atavapivant, certainly you've mentioned the lead, you have the body of data. Speaker 500:39:39But when you think about some of the nuances on On pan PK activation or even selectivity, maybe just help us understand the differences between mitapivit and the landscape? Thanks so much. Speaker 200:39:53Yes. Thanks, Greg. So I'll get started on your first question about the multibillion dollar opportunity or opportunities that I referenced in my prepared comments. That really comes from the fact that we're rapidly progressing in our pipeline moving from clear ultra rare with PKD into successively larger prevalent diseases. Some of those diseases I think are well characterized in terms of opportunity sickle cell for sure where there's been a lot of interest and A lot of therapeutic development focus. Speaker 200:40:30And here we're talking about moving from 3000 to 8000 patients across The U. S. And EU5 in the case of PKD jumping to just in the U. S. Alone 100,000 patients with sickle cell disease. Speaker 200:40:44But it's more than that. I mean, as we've already discussed this morning, we had this really exciting opportunity Relatively near term with a potential launch next year in thalassemia, which is a prevalence step up in the case of the U. S. From PKD sickle cell I just mentioned and then even after that with our other PK activator AG946 moving into low risk MDS. The great news about all this is we're moving in the right direction in terms of prevalence and that is allowing us to enter into very commercial opportunities. Speaker 200:41:23And it also allows us to navigate through the appropriate pricing dynamics as we go forward. But we are very excited Most importantly with the fact that as we advance our pipeline and as we've already noted, we have 2 back to back launch potentials with thalassemia next year followed by sickle cell disease in 2026. And then Sarah, you want to pick up for the next question? Speaker 300:41:47Sure. So in regards to PK activation and The differences between misopivat and some other PK activators. So we indeed while we stimulate PK, Different PK isoenzymes amongst which the PKR, which is important for the red blood cell, but then also PKM-two is important. Then we understand more and more The relevance of this specific isoenzyme in the context of the diseases that we are studying. As you know, Thalassemia, sickle cell disease, MDS, there is different components to these diseases in which stimulation of PKM2 may be relevant As it is expressed in immature red blood cells, it is expressed in other tissues that are also touched by these diseases. Speaker 300:42:40We are planning to further study this clinically as well, specifically in sickle cell disease In the kidney, as we know, kidney is such an important organ in the context of sickle cell disease and that many patients suffer from kidney disease and we believe that PKM2 may have an added advantage there. In regards to how that compares to other PK activator specifically as a propofab that is they this is the drug that used to be form a drug. They always spoke about being a PKR selective agent in regards to how they translate into other isoenzymes, they have not spoken about that. They have just highlighted their selectivity message. Operator00:43:29Thank you. Our next question comes from the line of Salveen Richter with Goldman Sachs. Your line is now open. Speaker 800:43:37Hi, this is Lydia on for Salveen. Thanks so much for taking our question. Just one on sickle cell, could you just discuss where you see ThyroKline fitting into the current commercial landscape just broadly. And then can you also speak to the commercial or the enrollment progression and any physician feedback you've gotten so far? Thanks so much. Speaker 200:43:55Sure. And maybe I will just start and then quickly turn it over to Sveta and then Sarah can pick up on The enrollment aspects, I mean, the fundamental premise of what we're driving towards with sickle cell disease is we believe that mitapivatpirakine has the potential to be what we refer to as foundational therapy. This is A very different mechanism of action as we've talked about, very unique from currently available options. We're increasingly Convinced that the benefits on making the red blood cells healthier really position it as such. And then the fact that this is an oral treatment only adds to that potential. Speaker 200:44:39But I'll let Sveta speak a little bit more about Not just how we're thinking about sickle cell disease, but the bridge as we go from PKD to thalassemia and then to sickle cell. Speaker 400:44:51Thanks, Brian. I'll start with sickle cell disease first, but as you said, we have a very important milestone with the thalassemia launch ahead of that, which we believe will be an important point from growing the commercial capabilities, executing on launch and after that capitalizing on sickle cell disease. When we think about sickle cell disease, Brian mentioned that and Sarah mentioned that already, The prevalence of the disease is 100,000 patients in the U. S, which is a significant step up from where we are today with PK deficiency. It's a disease where patients are diagnosed and the burden of disease is well characterized. Speaker 400:45:31At the moment, the outpatient population with sickle cell disease has very limited treatment options available. They are either improving hemoglobin levels, which is a case of a brighter, For improving VOCs based on the Phase II data and the target product profile we have for Firoquant for launch, We believe that we'll be very well positioned with Biokind to provide a treatment option which will bring benefits to Physicians, patients and ultimately payers as well by improving hemoglobin, reducing doses and ultimately improving the way patients feel and function and that's going to be a unique value proposition if we were to deliver on that profile. So we are very excited about that opportunity to come. But before we get to sickle cell disease, we are We're very excited to progress with our launch preparation for thalassemia as well. After we saw the results from the energized data in the year, we have definitely pressed the button and are actively preparing for a thalassemia launch to come in 2025. Speaker 400:46:44Similar to sickle cell disease, I think the thalassemia launch will be meaningfully differentiated in terms of market characteristics that compared to PKD And that will position us well for adoption of Firohind assuming approval in 2025, including again these patients are diagnosed, it's 6,000 diagnosed patients in the U. S. With thalassemia, well established ICD-ten cones, a stronger of the prescriber base and all of these elements gives us confidence on our ability to commercialize the product and drive adoption at launch. And similar to sickle cell disease, there is a better understanding of the thalassemia unmet needs across both the transfusion dependent but also the non transfusion dependent patients as well. So we are gearing up and getting ready to commercial organization launch in TELUSIMI in 2025 potentially followed by ZECTROBET launches in sickle cell disease in 2026. Speaker 200:47:46I was just going to say that's great, Sada. And I think everybody can sense our excitement about we have in front of us and I was just going to ask Sarah to make a comment about the progress with RISE UP Phase 3 for sickle cell. Speaker 300:47:57Exactly, because we're Equally excited to move towards those launches. So we are heavily focused on our Phase 3 enrollment, of course, right now. The trial is progressing as we are anticipating. There's a lot of enthusiasm both within our teams and of course on the by the investigators as well. And so everything is on track to deliver to the milestone that we have set out for this year. Operator00:48:24Thank you so much. Thank you. Speaker 200:48:26Thank you. Operator00:48:27Our next question comes from the line of Tess Romero with JPMorgan. Your line is now open. Speaker 900:48:36Great. Good morning, Brian and team. Thank you for taking our question. So switching gears a little bit to commercial PKD. Do you still think that PKD could be a $200,000,000 to $250,000,000 peak opportunity here in the U. Speaker 900:48:52S? And if so, how long do you think it could take you to get there? And then my second question is, We know that you're moving AG-nine forty six forward in lower risk MDS, but we were curious, have you Formally deprioritized the program in sickle cell disease as we hadn't heard anything on this in a while. Can you confirm if that's the case or not? Thanks so much for taking our questions. Speaker 200:49:22Thanks a lot, Tess. Actually the second question, we can handle that very quickly, which is No. And we have not deprioritized anything with AG-nine forty six. I think we're inspired by the potential. And at the right time, we'll provide updates about the progress, not just in our pursuits of low risk MDS, but also where we stand with respect to sickle cell disease. Speaker 200:49:46Cecilia, do you want to comment on the first one? Operator00:49:48Yes, sure. Speaker 400:49:48Thanks for the question. So we definitely remain excited about the opportunity PKD and we continue to expect those peak sales at $200,000,000 to $225,000,000 for the U. S. We continue to make progress each quarter and we're learning and as far as that, this is also based on capabilities for that launch. We think it's going to be slow and steady continuing to see the trends we've seen in 2020 3 for the next few years, but we do still maintain our peak of 200 to 225. Speaker 200:50:18Yes. I mean, with PKD We've talked about this previously, but in the deep commercial experience that both Sveta and I have across multiple Rare disease launches. This one's tough. It's a challenge. It is ultra rare. Speaker 200:50:33It's diagnostically intensive. There's long lead times for patients. So slow and steady is the right phrase. What we're continue to be inspired by each quarter is that persistency, which is something we saw relatively early with the launch of pyrokinin PKD. That is a really important feature as we think about chronic rare disease launches to come that are in our sites. Speaker 200:51:01And so we'll take the slow and steady path and we're going to continue to expect that going forward. But the way Pirate Kind is performing is what We believe really puts us in a position of strength as we approach energize sorry, I keep saying energize as we approach thalassemia as well as sickle cell beyond that. Speaker 900:51:24Okay. Thanks so much for taking our questions. Speaker 200:51:27You bet, Teth. Thanks a lot. Operator00:51:29Thank you. Our next question comes from the line of Greg Harrison with Bank of America. Your line is now Speaker 500:51:34open. Hey, good morning. Thanks for taking the question. Also just wanted to follow-up on AGN-nine forty six. How are you thinking just generally in development about development and potentially overlapping indications With mitapavat, if there could be improvement, for example, in sickle cell, like you discussed or even thalassemia? Speaker 500:52:03And what would you need to see from 946 in order to make that decision? Speaker 200:52:09Yes. I'll start and then Sarah can jump in. 1st of all, Greg, I hope we're in that position where we have multiple indications just as we have Right now with Thyrokine, one of the key advantages of at Agios of having really a leading PK activation franchises, we have not one, but 2 products that we're developing. And that allows us to have different economics, different pricing dynamics across the indications in between the products. I think there's a wide enough space for us right now given where we are in the development program with AG-nine forty six that we can tailor the appropriate target product profiles whether it's for sickle cell disease or for low risk MDS. Speaker 200:52:57In the case of low risk MDS, As I think folks know, we just reported out last year very encouraging Proof of concept from our Phase 2a study and we're in the process right now of making enhancements in the design so we can pursue Phase to be I feel very good about the work the team has done and that'll be the next step. And as I mentioned before, at the right time, we'll also report out the progress on sickle cell disease. Anything you want to add, Sarah? Speaker 300:53:28Just high level, I think what you can expect from development is that we always try to design our trials To meet multiple stakeholders, their needs, meaning we take our target product profile very seriously. So that is something That for 946 is the same. We take that very seriously and we incorporate we will be incorporating patient voice and the regulatory feedback obviously as well. Speaker 200:53:55Yes. And a great example of that is in the case of sickle cell disease, a point that we're very proud of that Agios is we have deeply involved the community. And in fact, Sarah and I attended the conference last year where we won an award from the community about How carefully and thoughtfully we involved sickle cell disease warriors and caregivers in how we think about designing the trials, recruiting for the trials and ultimately what the commercial profile should look like. And we'll do the same thing with AG-nine forty six. Speaker 500:54:30Great. Thanks for taking the question. Speaker 200:54:32You bet, Frank. Thanks. Operator00:54:33Thank you. And our last question will come from the line of Divya Rao with TD Cowen. Your line is now open. Speaker 1000:54:43Hi, guys. This is Divya on for Mark. I have 2 kind of follow-up questions. 1 on Eric's question earlier, Was the difference in the primary endpoint between mitapivat and luspatercept for the transfusion dependent patient something that was recommended to you by regulatory authorities or was it more of an internal choice? And then my second question is turning to the design of the Phase 2b in MDS. Speaker 1000:55:10Do you plan to test multiple dose levels of AG-nine forty six? And any color on the enrollment criteria versus what Reposil had in the KOMAMMZ trial would be great. Thank you. Speaker 300:55:22Awesome. Thank you. Thanks, Divya. So in regards to the first question, primary endpoint, yes, indeed, we do as I just mentioned on the previous question as well, we do Our development in collaboration with regulators, so we take feedback from the regulators very seriously and try to really incorporate the feedback as best as we can. And so that's how we ended up settling for the 50% endpoints in a rolling 12 week period interval, which we indeed truly is a more dynamic endpoint and really reflects the real world experience of a patient. Speaker 300:56:02So this is where it's always very good And we're always very grateful to be able to have those conversations because I do think incorporating feedback from multiple stakeholders always leads to better design choices. So that's that on the primary endpoint. And then in regards to your question for MDS Phase IIb, yes, the Phase IIb is indeed multiple doses that we are testing. We are going to test higher doses than we originally anticipated just Because we have learned from our Phase IIa that MDS patients overall have lower exposure to Same amounts of drug than other patient populations and healthy volunteers. So we are incorporating those learnings into our Phase IIb. Speaker 300:56:57And in regards to our inclusion criteria, we have not We haven't presented a trial in progress post or anything like that yet, but you can expect the population to be Relatively similar to how our population was in the Phase IIa. However, we will be focusing on transfusion patients with transfusion burden. It will also be a broad MDS population just like we allowed in the 2a. We're not excluding per se a population like Operator00:57:37Thank you. I would now like to hand the conference back over to Mr. Brian Gough for closing remarks. Speaker 200:57:44All right. Thanks a lot, Norma. And thank you very much everyone for participating in today's call. Very good questions, which we very much appreciate. As you heard today, our team has great conviction in our potential to deliver transformative new therapies to patients and significant long term value to shareholders. Speaker 200:58:04And we really look forward to speaking with all of you again soon. So thanks a lot.Read morePowered by
