Morning, and welcome to the Agios Second 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.

Speaker 1

Thank you, operator. Good morning, everyone, and welcome to Agios' 2nd Quarter 2023 Conference Call. You can access slides for today's call by going to the Investors section of our website, agios.com. On today's call, I am joined by our Chief Executive Officer, Brian Goff Doctor. Sarah Huynh, Chief Medical Officer and Head of Research and Development Sveta Milanova, our Chief Commercial Officer and Cecilia Jones, Chief Financial Officer.

Speaker 1

Before 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 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. And with that, I'll turn the call over to Brian. Thanks, Chris. Good morning, everyone, and thank you for joining us.

Speaker 1

Agios is focused on delivering transformative therapies For patients living with rare diseases and in particular, we're the pioneering leader in PK activation focused on hematologic diseases. In the Q2, we made significant progress advancing our industry leading pipeline of PK activators targeting hematologic diseases that share a common underlying pathophysiology. With each step forward, each data readout, The probability of success for the platform is strengthened and we are excited to share our updates with you today. As we articulated at the beginning of this year, we're prioritizing potential business development opportunities based on 5 key criteria: rare disease focus, transformative for patients, an identified regulatory pathway, potential to derisk early and a clear path to value creation. Earlier this morning, we were very pleased to announce a license agreement with Alnylam Pharmaceuticals, The leading RNAi therapeutics company that is highly aligned with these five criteria.

Speaker 1

Under this agreement, Agios will acquire the rights To develop and commercialize Alnylam's novel preclinical siRNA for the potential treatment of polycythemia vera or PV. PV is a rare and potentially fatal hematologic disease that affects approximately 100,000 patients in the U. S. And for which phlebotomy is the standard of care. Our goal is to address the high unmet need in PV by delivering a convenient disease modifying treatment option that reduces or eliminates the need for phlebotomy.

Speaker 1

This agreement is therefore aligned not only with our business development strategy, but also our core scientific expertise and clinical and commercial capabilities in rare hematology. We look forward to initiating IND enabling studies later this year. Sarah will provide more detail on the siRNA development candidate in just a few minutes. Also this quarter, we announced Positive results from the Phase 2 portion of the operationally seamless Phase twothree RISE UP study of mitotivat in sickle cell disease. The study met the primary endpoint of hemoglobin response for patients in both mitapivat treatment arms.

Speaker 1

And in recent weeks, our team has continued to analyze the results and has selected the 100 milligram dose for the Phase 3 portion of the study. We are now focused on Phase 3 execution and are quite eager to enroll the first patient later this year. Broadly, these results add to the growing body of consistent and compelling data that we have continued to generate with our PK activators, highlighting the potential of this differentiated mechanism of action to transform patient function, quality of life and long term outcomes across multiple disease areas. In fact, with more than 8 years of clinical Experience and the largest data set for any PK activator, pyracine has demonstrated consistent results across 3 distinct diseases. In this context, we were also pleased to announce this quarter that we've completed enrollment in both Phase 3 studies of mitapivat in thalassemia as well as the Phase 2a study of our novel PK activator AG-nine forty six in lower risk MDS.

Speaker 1

This progress reflects our operational excellence in clinical development and investigators' enthusiasm for the potential of PK activation in these indications. Based on this progress, we continue to expect 2 readouts from the Energize and Energize T Phase 3 studies in thalassemia next year and we've pulled forward the expected timing of the top line results for the Phase 2a study in lower risk MDS to the end of this year. Turning to our commercial business, we're encouraged to see that the consistent and compelling efficacy of mitapivat observed in the clinical trial experience Has continued to translate to persistency on therapy among adults living with PK deficiency in the real world. As we continue to maximize the opportunity in the current launch in PK deficiency, we're building the capabilities needed to fully realize The potential of anticipated future launches in thalassemia, sickle cell disease and lower risk MDS. Sveta will provide a detailed update on our commercial performance in just a few minutes.

Speaker 1

As you'll hear from Cecilia, we ended the Q2 with a cash position of nearly $950,000,000 on the balance sheet. One brief reminder, as part of the divestiture of our oncology business to Servier in 2021, we retain the rights to a potential $200,000,000 milestone upon FDA approval of vorasidenib and royalties on potential U. S. Net sales. We were encouraged by the results of Servier's Phase 3 trial and we look forward to tracking next steps.

Speaker 1

We're expecting a number of additional milestones by the end of the year, including enrolling more than half of the patients in the Phase 3 ACTIVATE Kids And ACTIVATE Kids T studies of mitapivat in pediatric PK deficiency, filing the IND for our PAH Stabilizer for the treatment of PKU and the newly added milestone, the data readout from the Phase 2a study of AG-nine forty six We're very enthusiastic about the clinical development momentum we're building and look forward to anticipated readouts from the Phase 3 studies of mitapivat in thalassemia in 2024 and readouts from the Phase 3 studies of mitapivat in sickle cell disease and pediatric PK deficiency in 2025. With that, I'll now turn the call over to Sarah.

Speaker 2

Thanks, Brian. Sickle cell disease is a serious, Potentially fatal hematologic disease that affects approximately 120,000 to 135,000 patients in the U. S. And EU5. Today, there are no novel oral treatment options that both improve anemia and reduce sickle cell pain crises and that is what we aim to deliver for these patients.

Speaker 3

Turning to

Speaker 2

the top line data of the RISE UP Phase 2 study, treatment with mitapivat demonstrated a statistically significant increase percent of patients in the 100 milligram BID mitapipat arm achieved the hemoglobin response compared to 3.7% of patients in the placebo arm. These increases in hemoglobin response were accompanied by improvements in markers of hemolysis and erythropoiesis as well as numerical reductions in the analyzed rates of Sickle cell pain crisis for this 12 week study. Specifically, patients in the placebo arm experienced an annualized rate of sickle cell pain crisis is of 1.71 compared to 0.83 in the 50 milligram arm and 0.51 in the 100 milligram treatment arm. The safety profile for mitapivat observed in the study was generally consistent with previously reported data for mitapivat in other studies of sickle cell disease and other hemolytic anemia and there were no adverse events leading to discontinuation in any study arm. And finally, of the 79 patients enrolled in the study, 73 continued in the Phase 2 open label extension period.

Speaker 2

These data further underscore the potential of mitapivast to address the high unmet need of patients with sickle cell disease By delivering a novel oral treatment option that both improves anemia and reduces sickle cell pain rights. We are excited to present the full analysis of the Phase to date up and have submitted an abstract for ASH later this year. Based on continued analysis of the compelling data observed at both doses in recent We have selected the 100 milligram dose for Phase 3. As a reminder, the Phase 3 portion of RISE UP will include a 52 week placebo controlled period in which 198 patients will be randomized 2:1 to either mitapivat or placebo twice daily. The primary endpoints are And we look forward to enrolling the first patients in the Phase 3 portion of the RISE UP study in the Q4 of this year.

Speaker 2

Turning to our broader development pipeline, we have been very pleased with the pace of enrollment across our programs in the first half of the year. We have completed enrollment in both Phase 3 studies of mitapivat and thalassemia, including Energize, which enrolled patients who are not regularly transfused with a primary endpoint of hemoglobin response and With a primary endpoint of transfusion reduction response. Together, these studies will deliver data relevant to the entire thalassemia population and thus allow us to evaluate potential of mitapivat to become the 1st oral therapy to improve hemolytic anemia and ineffective erythropoiesis across all thalassemia subtypes. We look forward to the readout of the Energize study in the first half of next And the readout of Energize T in the second half of next year. We were also pleased to complete enrollment in the Phase to a study of AG-nine forty six in lower risk MDS this quarter, several months ahead of schedule.

Speaker 2

AG-nine forty six is a novel PK activator that has the potential to strengthen our PK activator franchise. We now expect top line results from the Phase 2a study of AG-nine forty six in lower risk MDS by the end of this year, making this our next clinical data readout. As a brief reminder, the primary objective of this study is to establish proof of concept for AG-nine forty six And participants with lower risk MDS by measuring the following primary endpoints: hemoglobin response defined as an Increase of 1.5 grams per deciliter or more from baseline in the average hemoglobin concentration from week 8 through week 16 and transfusion independence defined as transfusion free for 8 or more consecutive weeks during the study for participants with low transfusion burden only. In parallel, we continue to advance the Phase 3 ACTIVATE KITs and ACTIVATE KITs T studies of mitapivat in pediatric PK deficiency and progress towards the filing of the IND for our small molecule PAH stabilizer to directly address the underlying cause of phenylketonuria or PKU. Finally, as Brian mentioned, we are pleased with the agreement that we announced this morning together with Alnylam, a pioneer in RNAi therapeutics with a best in class Polycythemia vera is a rare hematologic disease that is well aligned with our internal expertise.

Speaker 2

CV is characterized by excessive production of red blood cells, which leads to increased blood volume and viscosity and can result in thrombosis, cardiovascular events The siRNA development candidate targets TMPRSS6, a key driver of red blood cell production. Knockdown of TMPRSS6 increases hepcidin and reduces red blood cell production. We look forward to initiating IND enabling studies Later this year and leveraging our deep expertise in rare hematology as we progress this program towards the clinic. With that, I will now turn the call over to Sara.

Speaker 4

Thank you, Sarah. Our commercial organization remains focused on maximizing the opportunity in the current launch in PK deficiency By executing on our strategy across all phases of the patient journey, the capabilities we're building today On disease awareness and education, access and initiation and adherence and persistency We will also serve as a foundation to fully realize the potential of anticipated future launches in thalassemia, Sickle cell disease and low risk MDS. Our market research data continue to indicate That nearly 100 percent of our target healthcare providers are likely to recommend SpiroKine to their adult patients with PK deficiency. For clinicians, key drivers of these recommendations include Improvements in hemoglobin level, reduction in transfusion frequency and a positive impact on long term disease complications. To better understand the treatment experience on ThyroKine, we recently conducted interviews with a sample of patients for their caregivers.

Speaker 4

Most patients reported positive experiences, including improvements in hemoglobin and in energy levels, reduction in fatigue and decreased transfusion burden. Importantly, this feedback from both patients and clinicians Is consistent with the strong persistency of treatment use we observe in the real world after the initial payer reauthorization. Moreover, discontinuations remain low and reauthorizations have not been a barrier. In the Q2 of 2023, we generated $6,700,000 in net biopharma revenue, A 20% increase over Q1 this year. A total of 147 patients Have now completed a prescription enrollment form or PES, including 20 in the Q2 of 2023, A 16% increase versus the Q1 of 2023.

Speaker 4

This has translated into net 99 patients on therapy, an 11% increase over last quarter. Patients on therapy Continue to stem from a growing and the reverse provider base of 130 physicians and represent A broad demographic and disease manifestation range that is consistent with adult PKD deficiency population. Given the ultra rare nature of this disease, we continue to expect slow and steady uptake. In these early stages, we remain focused on identifying providers likely to treat adult patients with PK deficiency. Our efforts center on utilizing data and analytics to improve physician targeting as we believe there are a meaningful number of potential prescribers who may have adult PKD patients under management.

Speaker 4

We also continue to improve efficiency and impact, educating treating physicians and instilling a sense of urgency regarding the benefits of diagnosis and appropriate treatment. By doing so, we'll have to maximize the potential of the current launch and lay the foundation for potential launches in meaningfully larger patient populations. The first of these potential launches is in 2025 in thalassemia, where approximately 60% of thalassemia patients in the U. S. Do not have an approved treatment option.

Speaker 4

This next slide illustrates the breakdown of thalassemia subtypes in the U. S, including alpha and beta thalassemia and transfusion dependent and non transfusion dependent thalassemia. Importantly, mitapiva has the potential to become the 1st oral therapy to improve hemolytic anemia and ineffective erythropoiesis across the full range of thalassemia patients. Given the relative prevalence And competitive differences across thalassemia subtypes, we look forward to implementing a fit for purpose commercial strategy that leverages capabilities gained from the current launch. Together, the full range of telesimyr patients It's comprised of approximately 18,000 to 23,000 patients in the U.

Speaker 4

S. And EU5 And a meaningful addressable market in additional geographies such as the Gulf Council Countries or GCC where the prevalence is approximately 70,000 patients. The prevalence of sickle cell disease is also concentrated in the U. S. And GCC region.

Speaker 4

This overlap in select geographies provides an opportunity for us to leverage our commercial efforts in thalassemia to accelerate and support the future launch in sickle cell disease. With that, I will now turn the call over to Cecilia. Thanks, Vera. Our Q2 2023 financial results can

Speaker 3

be found in the press release we issued this morning and more detail will be included in our 10 Q, which will be filed later today. I'd like to take a moment to provide some context and highlight a few points. Q2 2023 net Piratin revenue was $6,700,000 an increase of $1,100,000 compared to Q1 2023. Aspiracind is the 1st therapy for its ultra rare adult PKD patient population, we continue to gather data and insights on the launch trajectory and will therefore not be providing guidance at this time, but we continue to expect a slow and steady trajectory to peak. Consistent with other rare disease launches, gross to net is expected to be in the 10% to 20% range on an annual basis.

Speaker 3

Cost of sales for the quarter was $1,100,000 Moving to expenses and the balance sheet. R and D expenses were $68,900,000 for the 2nd quarter, a decrease of $5,600,000 compared to the Q2 of 20 22. This decrease was primarily driven by a decrease in workforce related expenses as a result of reduced Headcount related to the evolution of our research organization in 2022. SG and A expenses were 30 point $4,000,000 for the Q2, an increase of $2,100,000 compared to the Q2 of 2022 That was primarily driven by an increase in stock based compensation expense. As a reminder, TIBSOVO royalty has ceased given the sale of our rights to 5% royalties on U.

Speaker 3

S. Net sales of TIBSOVO to Savard in October 2022. And 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 oracitinib and 15% royalties on potential U. S. Net sales.

Speaker 3

We ended the quarter with cash, cash equivalents and marketable securities of approximately $947,000,000 We expect that this pattern together with anticipated product revenue, interest income and the potential vorasidenib milestone We'll 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 from potential royalties from oracitanib, commercializing mitapivat outside of the U. S. Through 1 or more partnership or other potential strategic business or financial agreements. We are excited about our potential near term Thyrocan launch And continue to expect peak sales of $200,000,000 to $225,000,000 for PKD in the U.

Speaker 3

S. And $1,000,000,000 for worldwide revenues for PKD and thalassemia combined. 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 the potential additional launches of And continue to make strategic investments to advance and grow our pipeline, all of which impact our timing to profitability. Following the significant momentum created through the execution of our development plans and as we approach additional upcoming potential value creating milestones I am confident that our strong balance sheet will enable us to execute from a position of strength to continue to look for ways to create shareholder value. I will now turn the call back over to Brian for his closing remarks.

Speaker 1

Thanks, Cecilia. This was a tremendous quarter at Agios. We announced positive Phase 2 data in sickle cell disease, completed enrollment in 3 clinical studies, In licensed a compelling external program that has the potential to transform the course of a rare hematologic disease with profound unmet need and we continue to strengthen our commercial capabilities to support future launches. The data we continue to generate across Our industry leading pipeline of PK activators remain consistent and compelling, and we continue to make meaningful progress Towards our vision for Agios, which is to develop an established hematology franchise with approval spanning 3 hemolytic anemias and an expanded portfolio fueled by business development and advancement of our internal pipeline that is aligned with our core expertise in rare disease. As always, we'll continue to strive to be responsible stewards of our balance sheet and evaluate meaningful opportunities for value creation.

Speaker 1

Finally, I'd like to thank all of our employees for their hard work and dedication to our mission of transforming the lives of patients living with rare And all of our partners, including the physicians, patients, caregivers and participants in our clinical development programs. With that, we'll open the call for questions.

Operator

One moment for our first question. Our first question will come from the line of Greg Harrison from Bank of America, your line is open.

Speaker 5

Hey, good morning. Thanks for taking the question and congrats on all the updates. To start off, curious what factors Led you to the decision to license the PV treatment from Alnylam? And is this a model For future BD in terms of development stage and having the potential where you could add your own expertise and value. And then Would you expect this asset to be broadly applicable across PV patients or would it be more focused on the specific patient population?

Speaker 1

Sure. Well, good morning, Greg, and thanks a lot for the question. Yes, it's been a great quarter and I'm happy to provide some comments around the deal that we announced this morning. This is Polycythemia vera is a large market. We believe it is ripe for disruption in growth.

Speaker 1

And as I noted in my comments, if you just think about the standard of care, it's phlebotomy. And to us, That's just a great opportunity to do what we do best, which is reinvent the way that these rare diseases are treated and bring Potential disease modifying therapies to these patients. So we're really excited about this particular TMPRSS6 asset from Alnylam. It fits really well with our disciplined BD criteria, builds on our core capabilities and that's across our scientific expertise or development capabilities or commercial capabilities. And if you think about the BD criteria that we've talked about so many times, It checks all the boxes.

Speaker 1

So this is a rare disease. It is transformational potential for patients. We see an opportunity for early de risking, which we've talked about a lot as a sweet spot for us. We believe there's a clear regulatory pathway. And ultimately, this will be value creating is our strong belief.

Speaker 1

Because it comes from the Alnylam world class RNAi platform, we also have strong conviction in the probability of success from the data generated to date. So we're excited about this. I guess to your question of where we go from here for clinical development, I think and I'll Ask Sarah if she wants to make comments, but it's a little too early for us to define the target product profile specifically. We have many options. We'll be looking at efficacy dimensions, speed of action for the product itself for patients, Safety profile and of course convenience and all of those are in play.

Speaker 1

But given the stage of development, we're just going to pause and bring the asset in, Really look at it deeply for where we can put our development expertise in motion and then we'll provide updates accordingly. And then the last thing I'll just say to your point about is this a theme of the types of BD deals and so forth going forward. We retain optionality for a range of different BD deals. This one in particular, really, as I mentioned, checked all the boxes and so we were eager to bring it in, But we'll retain our disciplined BD criteria going forward. Sarah, anything you wanted to add?

Speaker 2

Only to say that we're very excited about this. We are, of course, once we move forward with program and have more details on our clinical development program. We will always be shooting to deliver value for patients and make a meaningful change with the development program and you can execution on the program as well.

Speaker 1

And we are excited to do that. Thanks, Greg.

Speaker 5

Great. That's helpful. Thanks.

Operator

One moment for our next question. Our next question will come from the line of Gregory Renza from RBC Capital Markets. Your line is open.

Speaker 6

Great. Good morning, Brian and team. Congrats on the progress and thanks for taking my questions.

Operator

Sure.

Speaker 6

Maybe just a couple of quick ones for me. Just following up on the in license on my own asset, maybe it'd be helpful just To hear your thoughts and Sarah's just on the preclinical data to date, certainly others Exploring manipulation of TMPRSS6 and just curious how you think this asset can potentially differentiate or assess up well when you survey The available data to date? And then secondly, great to see the dose selection for the Phase 3 in sickle. Just curious Just the rationale as you've looked at the volume data over the last several weeks since the top line and made the step to the 100 meg. Thanks so much and congrats again.

Speaker 1

Thanks a lot, Greg. And I'm going to send this over to Sarah then for both questions.

Speaker 2

Yes. Thank you. So around the Clinical data, so we are it has demonstrated in vivo proof of concept in non human primates with a safety A profile that was very favorable and very good knockdown of the target observed. So we feel very confident about that. And As we mentioned earlier, we're very eager to get going on the IND enabling studies and the CDP And provide more detail on that as we progress with that.

Speaker 2

I think for us, yes, there are others that are also looking at this To Brian's point, this is a very big market. There is going to be differentiation around efficacy, safety, mode of administration and also Frequency of administration, so we believe that our CDT will be able to deliver on what the market needs. And yes, again, very excited to get going on this. For your second question around the Phase 3 dose selection for sickle cell disease, obviously, we are Very excited. We're very excited about the data of the Phase 2 and we're very fortunate to have both doses, show benefit risk Profile that was favorable.

Speaker 2

We have pre specified criteria in the protocol and the team has time to now look at all of the data. So we followed that Framework and selected the 100 milligrams. We have not disclosed further details on the data. We mentioned that we have submitted the abstract to ASH And so are now awaiting the outcome of that and then we're hopeful to be able to provide all that detail at that conference.

Speaker 1

And Greg, maybe I'll just tag on too and say, I always love to take the opportunity to speak with pride about Sarah and her Hi, our R and D team. This is just a great example of the excellence operationally that we have and the efficiency Of the design of the RISE UP Phase twothree trial and the fact that we were prepared for both doses, we were thrilled To see that both doses were effective and now that we have the 100 milligram dose, the fact that we can proceed in the Q4 with the 1st patient dose in the Phase 3 trial, I think it's again just a mark of excellence and a real point of pride for the organization.

Speaker 6

Absolutely. Thanks, Brian, and thank you, Sarah.

Speaker 1

You bet. Thanks a lot.

Operator

One moment for our next question. Our next question comes from the line of Divya Rial From Cowen, your line is open.

Speaker 7

Hi, everyone. Thanks for taking our question and congrats on the quarter. This is Vivian for Mark. Just 2 from us. We're just curious, what do you define or how do you define success in the MDS trial?

Speaker 7

I know that there are other several mechanisms that are being touched in this space. Do you view those as Competitive or do you see those opportunities maybe to build combinations with AG946? And then I have a follow-up.

Speaker 1

Yes. Thanks, Divya. I will just start by saying, as is the case with all the disease areas that we're focused We have a very different mechanism of action with pyruvate kinase activation. And of course, The question for low risk MDS, this is with our other PK activator AG946. And I know Sarah will be eager to talk about what we're awaiting in terms of the Phase IIa data.

Speaker 2

So, yes, thanks for the question. So I think for the MDS program, I want to highlight here again that the For this mechanism of action for MDS patients, we are we have not declared our framework for MDS To define success, but it is a Phase 2a, so we are indeed looking for a signal of efficacy and favorable safety. And then our setup, if that's there, then we are set up to move fast into a Phase 2b in which we will do proper dose finding. It is indeed a market that is evolving and it's I think it speaks to that this is also a market that is ripe for a change. And we do believe that with this very differentiated mechanism of action, which is not being currently studied by Are not as fast far advanced by others that we really are set up for success there as well.

Speaker 2

And then I think what cannot be underestimated is that ours It's also an oral therapy, which provides the convenience of use for a patient population that is typically an older patient population.

Speaker 7

That's really helpful. And then just a quick question on the sickle cell program. Can you remind us on if you've disclosed the powering assumptions for the Phase 3 trial? And then, have you discussed The 100 milligram dose with the FDA or is that just mostly based on your internal discussion and analysis of the data?

Speaker 2

So, for the sickle cell disease program, the 100 milligram dose, so right now this is the internal Framework that we have applied and all of the data that we have assessed. We are very excited about the end of Phase To meeting with the FDA, we always look forward to our the constructive dialogue that we have together. And It's always great because I do feel like we are all wanting the same thing, right? For across all of our programs, we are really are shooting to deliver medications that have a favorable benefit risk and can provide change to patients. So we're always Very pleased with the constructive dialogue that we have.

Speaker 2

In regards to the powering assumptions, obviously, the Phase 3 is Much bigger sample size than the Phase 2. We for the So there's 2 endpoints there. For the primary endpoint, the hemoglobin endpoint, we use to leverage our internal data For all of the statistical underpinnings and then for the VOCs, obviously, we have been looking at other programs

Speaker 7

Thank you.

Operator

One moment for our next question. Our next question comes from the line of Salveen Richter from Goldman Sachs. Your line is open.

Speaker 8

Good morning. This is Anna Mida on for Salveen. Just one question from us on the licensing agreement with Alnylam. Given the novelty of the TFD siRNA modality for Agios, what gives you confidence in the clinical development process? Thank you.

Speaker 2

So, thanks for the question. So I think it gives us confidence because we do have Internal expertise that have worked on this modality, but also many other modalities. So it's not like while this is a new Compound or modality for Agios, it's not a new compound for Agios employees. And so we're looking forward to putting that internal knowledge to work. And I do think in the context of endpoints, Patient populations, all of that, it's straight into our wheelhouse of hematology drug development.

Speaker 2

And so we are looking forward to putting those skills to work there as well.

Speaker 9

Thank you.

Operator

One moment for our next question. Our next question will come from the line of Andy Behrens from Leerink. Your line is open.

Speaker 10

Hi, thanks. Congrats on the deal. My questions are also on the MDS program. I was wondering if you could give us some overview of how you see The PKR class in MDS, I think luspatercept is actually doing pretty well on that indication with sales over $700,000,000 in the subpopulation. Can you give us the physiological rationale for the PKR class in MDS as well as how you see it potentially being used relative to the EPO agents?

Speaker 10

And Lastly, I know it's early, but how do you think the usage of EPO agents in that disease hypothetically impacts pricing power?

Speaker 1

Yes. So Andy, thanks a lot for the question. I'll just start by reinforcing what you just said. We find it a very attractive Opportunity based on the current incumbents and the progress that they're making. The patient population as we had on one of our slides, We identify a 75,000 to 80,000 patients across the U.

Speaker 1

S. And EU5. It is another disease that is ripe for disruption And coming in with PK activation, a very different mechanism of action. And as Sarah has noted a couple of times already, on top of all that as an oral small molecule, We think has significant potential to be differentiated, but of course, we're going to be guided by the 2A data. You want to comment further, Sarah?

Speaker 2

Well, just on the part of the rationale why we believe PK activation may work in MDS, it's truly There are similarities between MDS and thalassemia that and we obviously have now progressed in thalassemia Quite well. So that is one piece. It also the glycolytic pathway is impacted in MDS patients at levels which we believe we can influence as well. There is hexokinase to pyruvate kinase ratio disruptions. There is also a fact that MDS patients often have an acquired PK deficiency.

Speaker 2

So there is a multitude of reasons why we believe PK activation may provide benefit. We have published data on this at EHA at ASH and hopefully more to come at ASH. So we are very excited about the evidence that we continue to build in this disease.

Speaker 1

And Andy, just one other comment I'll add is Our team goes deep across many potential therapeutic areas that we're focused on. And sitting with us today, we have Sveta Milanova, our Chief Commercial Officer, who We have been very involved in this space. And so it's early, of course, we're looking at Phase 2a data. But beyond that, Sveta will be able to add a lot of insight and expertise in not just the commercial profile of the product, but also as you asked about Pricing down the line and how we maximize the value creation. So we feel like we're really well prepared and cannot wait for this upcoming milestone by year end.

Speaker 10

Great. Thanks very much.

Speaker 1

You bet. Thank you. One moment for our next question.

Operator

Our next question comes from Tess Romero of JPMorgan, your line is open.

Speaker 9

Hi, Brian and team. Good morning. Thank you for taking our question. I thought I'd ask a commercial one today. For pyrokine, as you grow patients on drug, Just trying to get a sense of how you think about trajectory of new patient adds here.

It sounds like the drop off is pretty low. And do you think this run rate of 10 or so sequential net patient adds like you've seen in the last couple of quarters Is the right way to think about the launch going forward versus something maybe more accelerated given some of the initiatives on analytics, etcetera? Thanks so much.

Speaker 1

Yes. Thanks. Thanks, Esther. So, Sneda is thrilled to have a question about commercial. So, I'm going to let her comment.

Speaker 4

Hi, Seth. Good morning. So as I said, we continue to make progress on the launch. Most importantly, we continue to see the strength of the filokines profile in the real world, especially when it comes to persistency, the positive provider feedback and the payer support. At the same time, we also know that CKD is an ultra rare disease.

Speaker 4

And as we said to our Opening remarks, we would expect to continue to see slow and steady uptake. We will expect to see some variability quarter over Quarter, but our efforts continue to be laser focused on identifying the right providers, providers who are likely to have Patients with PK deficiency and patients who are appropriate for biokine either today or potentially in the future. And this is where our efforts in data and analytics continue to support our team as we continue to execute in the field. Very importantly, all of the capabilities we're building today serve as a very good foundation for us as we continue to look into the future And potential future indications, expansions for viral crime such as Celestema as well.

Speaker 1

Yes. I mean, the only thing I'll just add, Tess, This is a very unique kind of launch. It's pretty far on the ultra rare spectrum And we're building learnings from it, but I would look at it as slow and steady growth. And we always caution to just Be a little bit careful over quarter over quarter because it's it'll be lumpy for quite some time, but we are very proud of the progress that SED and the team continue to make.

Speaker 9

Great. And if I could just squeeze in a commercial follow-up there. Given these dynamics, how do you think about Providing longer term pyrokine guidance, is that something you feel like you may be in a position to do as we kind of exit 2023 and get into next year.

Speaker 1

Sure. Thanks, Cecilia. You want to add?

Speaker 3

Yes, I can take that. So as we mentioned before, this is a Ultra rare first therapy and we continue to learn data and insights. At this point, we're not going to give guidance. There will come a point we'll continue to evaluate when it's the right time

Speaker 1

Yes. Our anchor point as we've talked about peak sales $200,000,000 to $225,000,000 in the U. S. That's where we feel confident. We want to get more quarters under our belt until we give guidance on the revenue for And of course, the bigger picture for us anyway is that we're approaching, the readout of the thalassemia data.

Speaker 1

That's a meaningfully larger launch That has potential in 2025 and we may be in a scenario where we start to look at the collective guidance of multiple launches.

Speaker 9

Great. Thanks so much for taking our questions.

Speaker 1

Sure. Thanks, Seth.

One moment for our next question. Our next question comes from Danielle Brill of Raymond James. Your line is open.

Speaker 11

Hi, good morning guys. Thank you so much for the question. I also have a question on the in license So I know there are also antibodies targeting TMPRSS6 in development. I was wondering if you could elaborate on why you think siRNA maybe a Superior modality in this indication. Is it just a more convenient dosing regimen or do you think there might be an efficacy advantage as well?

Speaker 11

Thank you.

Speaker 1

Well, we so thanks a lot, Danielle for the question. We think there are, as I noted earlier, Potentially multiple opportunities for differentiation. TMPRSS6, we feel is now a well established pathway. I mean, very simply, The 90% knockdown of TMPRSS6 has an uplift effect on hepcidin, which decreases iron, which ultimately lowers the red blood Cell production, that thread through that mechanism, we feel through all of our diligence very confident Ian, and as I said, I think there will be opportunities for efficacy. Safety, of course, will be That's one when you look at some of the current opportunities therapeutically for patients, there's plenty of room for improvement.

Speaker 1

And then it could wind up also being a meaningful convenience opportunity because siRNA Classically and particularly from the Alnylam platform has proven that that is a mechanism that has delivered benefit to patients with lower But we're going to look at all of that. It's very early and we will start our IND enabling studies this year and then we'll report out our progress accordingly.

Speaker 11

Thanks so much.

Speaker 1

Sure. Thank you.

Operator

Thank you. And we're showing no additional questions. So we will turn the call back to Brian Goff for a final comment.
