spk11: quarter, these achievements were highlighted by the publication of our global phase three program results for Vatadustat in the New England Journal of Medicine. And more recently, FDA acceptance for filing of the Vatadustat NDA for the treatment of anemia due to chronic kidney disease in both adult patients on dialysis and not on dialysis with a PDUFA target action date of March 29, 2022. Putting all this together, as there are currently no approved HIF-PHIs to treat anemia due to CKD in the U.S., we believe that AdduCet is positioned as a potential first-in-class product, and that these achievements bring us one step closer to having a novel oral therapeutic available for patients living with this disease. This is an exciting time in Akiva, and we believe we have a tremendous opportunity ahead of us. which is why I want to spend some time this morning and really remind everyone of the clarity of the global phase three data for Vatadustat, our clinical development program, and Vatadustat's potential market opportunity in dialysis, which we believe is now broader than originally anticipated. I also want to underscore the significance of our existing commercial footprint. We've established a strong reputation in the kidney community with our commercial product, Arixia, And we look forward to leveraging both our nephrology-focused sales force and our expertise upon the launch of Vatadustat. And of course, all my comments today regarding the launch of Vatadustat, its adoption, and use are all subject to its regulatory approval. So let's begin. We believe strongly in Vatadustat's potential as a treatment for anemia due to CKD. And we're excited with the prospect of having Vatadustat lead a new class of therapeutics and help people living with this disease. Today, there are approximately 560,000 dialysis patients in the United States, a number that will continue to grow as the overall population ages. In general, this is a group of patients with significant health issues. Approximately 90% are being treated with erythropoiesis stimulating agents, or ESAs, to manage their anemia. The impact of this disease on patients with CKD is profound. In addition to the well-known symptoms of fatigue, dizziness, and shortness of breath, anemia has been associated with more severe adverse outcomes, such as cardiovascular complications, including left ventricular hypertrophy and congestive heart failure. Multiple large peer-reviewed studies have demonstrated the increased cardiovascular risk associated with ESA use in both dialysis and non-dialysis patients. Physicians and key opinion leaders associate that risk with the speed of hemoglobin increase and hemoglobin overshoots above their target level. These concerns were raised recently in the context of the FDA's review of another company's HIF-PHI product under development and their newly disclosed adverse event data. While we will not speculate on the outcome for their company or their data, we believe there are differentiating and important aspects of the global phase three data for Vatadustat and our program. As the Vatadustat MDA is actively under review at the FDA, I'll limit my comments to our public data, which fortunately there's an abundance of, and it's published in one of the most reputable journals in the world. Our team has done a great job executing on our publication plans. First, our global phase three clinical data showed that once daily dosing of Vatadustat increased hemoglobin in a gradual and steady manner. The data also showed that Vatadustat minimized hemoglobin overshoots compared to darbopoietin alpha and ESA. We have been highlighting this treatment goal in the design of our studies for a number of years. And it's encouraging to see this approach validated in the phase three results across both our dialysis and non-dialysis programs. I'd also like to remind you that our entire Global Phase III program, including the starting dose used in both dialysis and non-dialysis programs, was designed after extensive dialogue with both the FDA and European regulators. This was a very significant undertaking, and we're very pleased that it enabled us to align with regulators on the details of our statistical analysis plan, the pre-specified analyses, and the non-inferiority margins. We're also grateful to have the support of the chairs of the Independent Executive Steering Committee for both Innovate and Protect, Drs. Chertow and Eckert, and the entire committee, who have continued to ensure the ongoing quality of our program, as well as an objective, independent voice in data analysis and publication. Having the results of our Global Phase III program published in the New England Journal of Medicine was tremendous validation of all of this work. We believe these publications not only reinforce the scientific rigor and quality of our program, but also speak to the clarity of the data for the broader medical community. This is one more tangible example of Akebia's commitment to transparency. Feedback and interest in these publications from key opinion leaders and the broader kidney community continues to be very positive. We believe these publications will be highly informative for physicians, patients, dialysis providers, and payers, as they make important decisions about patient care, and potentially a key consideration when differentiating among HIFs in the class, as well as differentiating Vatadustat from treatment with ESAs. Importantly, as seen in the New England Journal publications, our global Phase III data showed no significant safety signal on adverse events, including thromboembolic events, seizures, and infections. More specifically, the data showed that these events were very similar for Vatadustat as compared to darbopoietin alpha in the dialysis and non-dialysis programs. We've provided the links to these journal publications in today's press release, and of course, they are also available on our website. I encourage you to read these papers and the supplementary data as well. as we believe they will provide a very clear understanding of Vatadustat and our program. And of course, we have Dr. Burke, our chief medical officer, on the call today to answer any questions you have about the journal publications. With Vatadustat's PDUFA date set for March, we're progressing on the path to commercialization and are highly focused on prelaunch activities to ensure that we are well positioned for successful U.S. launch in 2022 subject to regulatory approval. More recently, with the exciting potential for Vatadustat to now be first to market, we've been expanding our planning to include a broader market opportunity in dialysis than originally anticipated. We believe dialysis represents a large and growing potential $2 billion market opportunity in the U.S. alone. We believe we have a clear path ahead of us in dialysis, and we're confident that upon U.S. approval, we will have the potential to address the unmet needs of over half a million adult patients on dialysis and rapidly establish Vatadustat as the new oral standard of care for the treatment of anemia due to CKD. We anticipate that the consistency and clarity of our dialysis data, bolstered by recent publication in the New England Journal, will play a meaningful role in helping develop treatment protocols within dialysis providers which are critical to driving adoption in the dialysis market. We're also conducting two studies, one led by our partner Otsuka, to show that Vatadustat can also be dosed three times a week. Assuming the data are positive, we expect to use this data to support a supplemental NDA for this dosing regimen post-approval. Although the significant majority of dialysis patients are cared for in center, several factors, including the COVID-19 pandemic, are supporting a growing shift towards home dialysis. Based on reports from the largest dialysis providers, home dialysis appears to be the fastest growing segment of the dialysis population. CMS is also creating payment models to encourage this move to home treatment. These trends are exciting as we believe that as a convenient once daily oral therapeutic, Vatadustat has the potential to offer an important value proposition, both to the growing number of home dialysis patients and to dialysis providers looking to better support these patients, simplify administration, and grow their home programs. With our planned commercial launch and strategic alignments, we believe that we can enable broad market access for patients and support rapid adoption of that Adustat in the dialysis market. As a potential first-to-market product, our go-to-market strategy now has a broad focus. Our plans include leveraging our exclusive distribution relationship with B4 Pharma to access Fresenius Medical Care and certain independent dialysis providers, which include up to 60% of the U.S. dialysis patients. Additionally, we plan to leverage our direct nephrology-focused sales force to facilitate adoption at DaVita and other strategically important dialysis providers that account for the remaining 40% of patients, with our partner Otsuka sharing in the launch costs and responsibilities. Adding to this, is a unique reimbursement model in the U.S. dialysis market with Tdapa, an add-on payment to the bundle that's intended to encourage adoption of innovative therapies by clinicians and dialysis providers. Although there is limited market experience with the Tdapa process, our understanding of the process suggests it may take approximately six months from regulatory approval to Tdapa designation. Now, as TdapA payments will continue for two years following TdapA designation, we believe that the timing of TdapA designation will be important to the rate of adoption. Again, as a potential first-in-class product, we now believe Vatadustat has a broader market opportunity in dialysis than originally anticipated. And we believe we created a go-to-market strategy to support both our near-term and long-term growth potential in this market. Now turning to non-dialysis. Consistent with our prior comments, while we remain cautious for approval in non-dialysis, we believe we have put forward a compelling and extensive NDA data package, and we look forward to continuing to work with the FDA in their review of the efficacy and safety data. We believe the patient need for a safe and effective oral treatment for anemia due to CKD is clear across both the dialysis and non-dialysis populations. Now shifting gears to performance of our existing commercial product, Arixia. We're encouraged with Arixia's performance in the second quarter. We continue to be pleased with how the market is viewing Arixia's strengths. And importantly, the team continues to do a great job supporting our customers and patients, getting our therapies to those in need. We're hopeful that as the industry continues to focus on prioritizing vaccines for dialysis patients, COVID-related hospitalizations and mortality will continue to decline. We continue to expect Erixia to deliver annual revenue growth for 2021. And again, we're excited to leverage this outstanding team with the expected launch of Vatadustat next year. Finally, I'd like to share with you a number of potential catalysts that we're focused on for 2021 and beyond. As our largest potential market, the U.S. remains our highest priority for Vatadustat, with a PDUFA target action date of March 29, 2022. We're also continuing to collaborate with our partner, OTSUKA, and expect to file Vatadustat's MAA submission to the European Medicines Agency later this year. We continue to explore potential development opportunities for Vatadustat and look to share more information on these efforts later this year. As we've discussed previously, UT Health is engaged in an ongoing investigator-sponsored study of Vatadustat as a potential therapy to prevent and lessen the severity of acute respiratory distress syndrome, or ARDS, in adult patients who've been hospitalized due to COVID-19. They currently have over 300 patients enrolled in this 400-patient study, and when possible, we'll share an update on the study. We look towards additional presentations of our Phase III results and data, including multiple abstracts expected at ASN and at future medical conferences and in peer-reviewed journals. Lastly, as we move closer to the potential launch of Vatadustat, we'll also look to share progress on our pre-commercial activities. So to briefly summarize, this is a busy and exciting time at Akiva. We remain confident in Vatadustat's potential as a first-in-class treatment for anemia due to CKD And we look forward to continuing to engage with the FDA in the review of our NDA. I'll now turn the call over to Dave, who will review our financial results.
spk07: Dave? Thank you, John, and good morning, everyone. As John mentioned, having laid the groundwork for potential approval, we're advancing pre-commercial launch preparations for Vatadustat. We believe we are well positioned with our existing commercial footprint, and together with our partners, our team is fully engaged in the work to ensure appropriate commercial drug supply at the time of launch, subject to approval. Turning to our financial results for the quarter, starting with revenue. Total revenue is $52.9 million in the second quarter of 2021, compared to $90.1 million for the second quarter of 2020. reflecting lower collaboration revenue consistent with successfully completing our global Phase III clinical development program for Vatavistat. In terms of Akibia's commercial performance, net product revenue for Orixia increased 7.4% to $33 million for the second quarter of 2021, compared with $30.7 million for the second quarter of 2020. We are encouraged by this growth, which we believe is a great illustration of our commercial team's execution in this ongoing COVID-19 environment. We believe this performance also highlights Arexia's favorable product profile and the critical nature of this therapy. Looking ahead, we believe the team's focus and execution on our marketing, sales, and payer strategies will continue to drive net product revenue growth. Turning to expenses. We continue to prioritize investments to support both Vata-Dustat and Topline growth, while also continuing to focus on improving costs and advancing our pipeline of development opportunities. Cost of goods sold was $52.5 million for the second quarter of 2021, compared to $174.6 million for the second quarter of 2020. Current year includes a $30 million non-cash charge for excess purchase commitments consistent with continued execution of our long-term payer contract strategy, which remains focused on contract economics and net product revenue growth. Cost of goods sold for the prior year period included the impact of a non-cash impairment charge of $115.5 million related to the Arixia intangible asset, in addition to other charges noted in our press release for that period. Research and development expenses were $37.2 million for the second quarter of 2021 compared to $52.8 million for the second quarter of 2020. The spending reduction was primarily driven by a decrease in costs consistent with completing the Innovate and Protect Global Phase III clinical programs. We expect that R&D expenses will remain significant as we continue to support ongoing planned clinical work as well as the cost of our supply chain and inventory billed ahead of the expected approval of Vatadustat. For clarity, we would like to remind you that consistent with the terms of our collaboration agreements for regions including the U.S., Europe, Japan, and others, Vatadustat supply chain costs are shared with our partners respectively. Selling, general, and administrative expenses increased to $41.7 million for the second quarter of 2021, compared to $35.5 million for the second quarter of 2020. The increase compared to the prior year period was due primarily to higher marketing expenses as we prepare for a potential launch of VAT abuse debt subject to approval. As our commercial team is already in place, we expect only a modest increase in SG&A for the remainder of 2021 to support these efforts and Erixia growth. For our bottom line, net loss was $83 million for the second quarter of 2021 compared to $175.8 million for the second quarter of 2020. The improvement in net loss compared to the prior year period was due primarily to the non-recurrence of the one-time impairment charge in the prior year quarter, as well as lower operating expenses, partially offset by lower collaboration revenue for the second quarter of 2021. Turning to our capital position. We ended the second quarter with $247 million in cash equivalents and available for sale securities. Our Q2 cash balance includes the impact of $37.3 million in net proceeds from sales of stock under our ATM in the second quarter. We also received $16.1 million in net proceeds from sales under the ATM subsequent to the quarter end through July 16th. We believe that our cash resources will be sufficient to fund our current operating plan through at least the next 12 months. Additionally, we believe our cash runway would extend beyond that period, assuming timely regulatory approval of Attadee's debt and the receipt of associated regulatory milestones. With respect to future milestone payments to Akiva, I'll remind you that subject to the terms of our collaboration agreements with OTSUKA, Akibia has the right to receive milestone payments from OTSUKA upon the approval of Vatadustat in U.S. and Europe. Given the tiered nature of these milestones, if Vatadustat succeeds in being the first HIF-PHI to market in the U.S., the U.S. regulatory milestones from OTSUKA are estimated to be $15 million and $50 million for dialysis and non-dialysis indications, respectively. Additionally, there are significant sales and commercial milestones. As a part of our existing R&D funding arrangement with OTSUCA, up to 50% of these milestones may be used to offset accumulated R&D pre-funding, which today stands at $100 million. In addition, consistent with the terms of our license agreement with V4, Akibia has the right to receive a $25 million milestone payment upon U.S. approval of Vatadu's debt and its inclusion in the prospective payment system or Tdapa, whichever is first. With that, we'll open the line to questions. Operator?
spk03: Thank you. Ladies and gentlemen, to ask the question, you will need to press star then one on your telephone. To withdraw your question, press the pound key. Again, that's star one to ask the question. Please stand by while we compile the Q&A roster. Our first question comes from the line of Chris Raymond with Piper Sandler. Your line is open.
spk04: Hi. This is Allie Bradson for Christmas Morning. So just a couple questions from us on Vatadustat, kind of based on the RoxaDustat adcom. So first, could you talk to how the outcome of the Roxa panel changes your thinking on the likelihood that FDA will convene a panel for Vatadustat? Second, just on the population used for the Vatadustat MACE analysis, Could you just confirm that your MACE analyses were shown on an on-study basis rather than an on-treatment basis? I guess that was our read of the stats plan in the NEJM articles, but it was an area of debate during the ROCS ad comm, so I wanted to verify. And then last question just on dosing. So you saw a slower rise in hemoglobin for Vatadustat than for ESAs and Innovate and Protect, so that does seem to validate the dosing scheme used in your Phase 3s. But just hoping you could talk to your confidence that you've identified the right QD dosing protocol that will be acceptable to regulators. And maybe related to that, kind of how does the discussion at the FDA, by the FDA at the ADCOM, just on roxidustat dosing and the rapid increase in hemoglobin, maybe change your view on the approvability of the three times weekly regimens that you're exploring with vetidustat. Thanks.
spk11: Good morning, Ali. Thanks for the questions. That was kind of a long list, so hopefully I jotted them all down and we can get to them all because we're happy to answer them all. So your first question was about the likelihood of a panel for Vata-Dustat now. Again, the last communication we had around the panel with the FDA, as we've said previously is that they said not to expect the panel. I don't think it's worth speculating whether it's more likely or less likely at this point, but as we said back then, even before the ROXA DUSTA panel, we're planning for one and we're preparing for one. So if we learn from FDA that they would like to hold the panel, we'll be ready for that. But we haven't heard any update on that. Your second question was around the population for the analysis. Was it on treatment or on study analysis? And I'm going to ask Dr. Burke to comment on that. Steve?
spk10: Yes. As outlined in the New England Journal of Medicine publications, it was an intent to treat analysis in the safety population. So if a patient was randomized and received a dose of study medication, we followed those patients until the very end of the global study completion date. at which time we announced the closure of the study and asked the sites to bring the patients back in for their end of treatment and end of study visit. So it's a pure intent to treat.
spk11: And I think that's one of the strengths of the way we designed the studies. And again, did that in consultation with the regulators, but it was a true MACE study where because you had an act of control, you were able to continue to follow the patients. I think your third question revolved around the dosing regimen and the gradual dose. And again, I'll pass it to Steve for that one.
spk10: Right. The dosing regimen was designed in collaboration with the FDA, including the starting dose. And it was designed to have a gradual and sustained increase in hemoglobin while minimizing hemoglobin overshoots, rapid rises in hemoglobin, and this is described in the New England Journal of Medicine paper.
spk11: And, again, I mean, we've said we've been, I think, saying this for years now, but, you know, we did have this discussion with the FDA before. If you recall, our starting dose in the Phase II studies was 450 milligrams a day, and in consultation with the agency, and really focused on that concern about too rapid a rise in hemoglobin, you know, we said, again, in consultation, went to a 300 milligram starting dose for both dialysis and non-dialysis. And I think, importantly, the results speak for themselves, right? You see that gradual rise. You see fewer overshoots. So, you know, from that perspective, I mean, this is why we have so much confidence in the data. The efficacy data in both dialysis and non-dialysis is very clear. Physicians aren't in a rush to get hemoglobin elevated higher. Doing this over time, avoiding those overshoots, and keeping them in the range long term, that's what they're looking for. And again, that avoiding overshoots, I think we heard, is something that the FDA is really concerned about, and we feel quite good about how we designed the program, and maybe more importantly, the data that the program generated. So your third question revolved around TIW. You know, that is, our TIW studies, Modify and FOCUS, are ongoing. Modify is fully enrolled. FOCUS is enrolling now. We have, I think, most importantly, you know, obviously when we see that data, we'll give you an answer as to, you know, the viability of that three times weekly dose. Again, we saw in phase two, in a small phase two, that we were able to do that, but those are ongoing studies. We know we have a safe and effective once-daily dose in dialysis, and that's the dose that we'll be launching with, assuming regulatory approval. And, again, the data is so clear that that works. I don't know, Steve, if there's anything you want to add on the TIW. No? Okay. Did we cover all your questions, Allie?
spk04: Yes. Thank you.
spk11: Thank you.
spk03: Thank you. Our next question comes from the line of Bert Hazlett with BTIG. Your line is open.
spk12: Yes, thanks. Congratulations on all the progress. Just with regard to the – could you put a little more meat on the bone with regard to home dialysis and the Tdapa process? Kind of the efforts that you're considering, you know, longer-term with home dialysis and then maybe more near-term with Tdapa – and kind of what the gating items are. And then secondly, could you also talk a little bit more about your commercial Salesforce infrastructure post-approval? Thanks so much.
spk11: Great, Bert. Thanks for the question. So, of course, home dialysis and TDAPA are both dialysis issues, so they're related but not exactly the same. And I'm going to turn to Del to – to ask, maybe start on home dialysis.
spk09: Yeah, absolutely. Thanks for the question. We feel like we're in a real position of strength as you think about home dialysis. You know, clearly our data is under review with the FDA, so we're not sure exactly what our final label is going to look like, but when you think about the clarity of our Phase III data, when you look at the things that John just talked about, relative to the gradual steady rise, hemoglobin overshoots, and I think then thinking about the dosing, it really does align very well with the home dialysis population. And this is a population that is growing at about 15 percent a year right now. It's the fastest growing segment of the market, and we feel like Vatadustat is really well positioned upon approval to drive rapid adoption there through the dialysis organizations.
spk11: I think to speak to your second question, you know, I just wanted to emphasize something on the home. I mean, Del said it exactly right. I mean, this is a growing population. In-center is still the largest population, but you look at all of the initiatives that are coming out today, they are all focused on giving patients more choice and getting patients out of the center to home. And I think the COVID pandemic is the clearest example of why that matters. You know, the mortality rate in the dialysis population, as we've talked about before, was, you know, small studies at 20 to 30%. Having all these people in center is a challenge. And CMS is even putting different payment programs, ESRD treatment choice, ETC program, which is encouraging, which is a mandatory program, that encourages dialysis providers to move patients to the home setting. And so, this is going to continue to be a fast-growing segment. To be sure, we think Vatadustat has applicability and will be used in both home and in center, but home is just such a clear opportunity for a once-daily dose. Tdap is another really important opportunity for us. So, I mean, this is Not a lot of people have gone through it. None have gone through the Tdapra process. So, you know, we think we understand it, but we'll learn more as we go. But, Del, you want to talk about that?
spk09: Del Rosario- Yeah, sure. You know, our understanding of the rule is that the rule is, seems very clear. And, you know, our, we believe that Vatadustat will be eligible for Tdapra coverage. The coverage period will be two years once approved. And essentially, you know, our understanding is that based on the quarterly coding system, we'll apply as soon as possible after approval. And at that point in time, there'll be some time in between. We think it could be about six months before we receive Tdapa reimbursement. And we think that'll be, you know, a key in patient adoption as we launch and really looking at the revenue ramp for the product. And I think our commercial infrastructure is really set up to help us launch quickly. Right now, we have a commercial team that is about 142 people. The majority of those are field-based employees and supporting Arixia today. And this is a really experienced nephrology sales force, and they have a strong reputation with nephrologists and the DO community. And when you look at our promotion with Orixia in dialysis patients with hyperphosphatemia, the overlap is so strong with where we'll be when we launch Vatadustat that we feel like we really have the right commercial leverage to launch well and to launch quickly.
spk11: The only thing I'll kind of emphasize on the Tdapicide, Del, thanks for that, is, again, we're going to see exactly how this comes down. We will launch right after approval as quickly as we can, and we'll go through the Tdapa process as quickly as we can. Remember, it's very important for the dialysis providers at that point when they have access to the drug after approval to start working on their protocols. They need to have those protocols in order to really convert all of those patients. So the timing actually works quite well. I think we just wanted to emphasize you know, that process because, as Del said, it really will influence the speed of the ramp, you know, having that TDAPA reimbursement. So that's – I just wanted to make sure we were really clear about that. Does that help, Bert? Yeah, that does.
spk12: Just a quick follow-up, if I could, actually, just to shift. With regard to manufacturing and CMC, are any of those issues gating items with regard to the progress of the NDA? Just a quick one.
spk11: No gating items for it seemed. Obviously, all of that was part of our NDA, and we're confident we'll have multiple drug product, drug substance manufacturers is our plan, and that was included in our NDA. So we feel fine about that.
spk12: Terrific. Thanks so much.
spk03: Thank you. Our next question comes from the line of Althea Young with Cantor Fitzgerald. Your line is open.
spk01: Hi. Thanks for taking my questions, and congrats on the progress. This is Nina on for Aletheia. We were wondering if you could just share some differences in the market dynamics for dialysis and non-dialysis in Japan, the U.S., and Europe, and also if you could share how much more investment is needed for the dialysis launch if approved in 2022, since you already have a sales force broadly in place. Thanks.
spk11: Thank you for the question. So, you know, I'll handle the market dynamics kind of in a general sense. So the U.S. market is, you know, the dialysis and non-dialysis markets are quite different from a reimbursement perspective, treatment perspective. You know, we've talked a lot about that. The non-dialysis patients are generally not treated with ESAs because of the safety concerns, the difficulty of acquiring the product, the fact that it's injectable, whereas dialysis patients are routinely treated with an ESA. So, you know, as we think about the dialysis market in the U.S., it's a market where we take share, and in the non-dialysis market, it's where we, you know, are growing the size of the market opportunity. Europe, vis-a-vis the U.S., I mean, it's a little bit smaller dialysis market, and You know, it's hard to talk about Europe because every country in Europe is quite different. You know, the U.K. has very large, very few dialysis centers, where in Germany there's, you know, hundreds of very small dialysis centers. The other difference is that non-dialysis patients are more frequently treated with ESAs in Europe, so the level of concern around safety has never been as high in the in the European market for the non-dialysis population, and, you know, the access has been good. There's also more biosimilar products available in the European market. Japan is, you know, dialysis patients, and they are treated. These are more healthy patients because there's no transplant. It's culturally not kind of acceptable in Japan, so healthy patients stay on dialysis, so their outcomes usually are quite good, and they stay on it. I think similarly, you're looking at growing the non-dialysis market in Japan. Del, did I miss anything there? No, I think you covered it all. I think it was good.
spk03: I missed the second question. I think the last question was relative to the investment in the U.S. commercial emphasis.
spk09: Del, do you want to? Absolutely. Absolutely. As we said, we really feel like with our existing commercial infrastructure, we're really in a position of strength here to launch Vatadustat. And we're excited about the opportunity that lies ahead. We feel like we have the right experience in our sales organization. And when you think about what we're going to need to add Vatadustat to the bag, so to speak, and support the portfolio, we really think the investment is going to be very incremental from where it is today. We collaborate closely with Otsuka, and we'll work together with them to create the deployment that maximizes Vatadustat's launch, but we really feel like overall we have a coming at it from a position of strength and won't need a whole lot more. Thanks, Del.
spk01: Thank you.
spk10: Thank you.
spk03: Thank you. Our next question comes from the line of David Lebowitz with Morgan Stanley. Your line is open.
spk05: Hi, this is Avatar Jones on for Dave this morning. A few questions from us. First, have you received questions from FDA on the causality of MACE events? And if so, how do you plan to address those? Secondly, so aside from rapid hemoglobin rise, Rox's panel, they hypothesized that the MACE events could be related to nonspecific HIF inhibition. Can you comment on Vatadustats in that regard? And then lastly, can you offer any updates on the progress of Oryxia's litigation and coverage? Thank you.
spk11: Great. Thank you for the... for the comments. So we are in discussions with the FDA now in kind of the normal review process. Won't speak to the nature of them because they look broadly. It's a very, very robust package. And again, we have confidence in the data, and so we feel confident in being able to answer any of the questions that FDA raises. Commenting on the panel or the fact that they brought up this idea that there may be nonspecific HIF kind of off-target effects, I think it's really important to look at the data. I think that's kind of where I think FDA will always land is what does the data tell us? You know, we are very confident in the safety profile that we've generated with Vatadustat. I don't know if that data was driven because we have the right dosing regimen or because of the differences in the product. We have the data to support the safety and efficacy of Vatadustat, and we believe that's what matters. And, you know, we've always recognized the complexity of the HIF pathway, and back before Any of us who are in the room here today were with the company, and we selected Vatadustat as a product for development based on the characteristics that were going to give it the most kind of preference for increasing EPO and managing anemia. So we're really quite confident in the product, and we're quite confident in the product because of the data that we've generated. And then the third question was around Arixia litigation, and that is ongoing. And, you know, as soon as we have any further updates beyond that, we will update you.
spk05: Excellent. Thank you.
spk11: Thank you.
spk03: Thank you. Our next question comes from the line of DeFay Yang with Mazuho Securities. The line is open.
spk06: Hi. Thank you. This is Dan Clark. I'm for DeFay. First question from us, has the feedback from the nephrologist community changed following the outcome of your competitor? We'd be curious to know, you know, anything you've heard regarding VATA versus ESAs and VATA versus other oral HIPs from them. Thank you.
spk11: So, you know, I think it's obviously early, and this is a long process of communication, but we are very encouraged by the conversations we have with nephrologists. I mean, Remember, the difference that Adustat brings to the table here is that the nephrologist can go directly to the New England Journal of Medicine and review the data in full. That makes a huge difference, the credibility of that publication. Again, we don't talk about it, I think maybe we don't talk about it enough. The lead authors on each of those papers in the New England Journal were the co-chairs of our independent steering committee for Innovate and Protect. The analyses in the New England Journal, the abstracts that show up at the scientific meetings, The analysis of the data in general from the beginning have been overseen and done in collaboration with this independent steering committee, and that, I think, brings great credibility to the data, to the process, and at the end of the day allows us very significant differentiation. I don't know if Steve or Dale, Dale, you want to add something?
spk09: Yeah, I think certainly recent market events create perceptions and some confusion in the marketplace, and we certainly hear that from nephrologists. But I think as the potential first-in-class product here, we have a lot of work to do moving forward in ensuring that we are differentiating Vatadustat from other HIFs and ESAs, as well as ensuring that people are really clear on the unmet need, which we believe is still very substantial, and nephrologists understand that as well.
spk11: That might have been the most important thing that came out of the adcom was that hour of open discussion where you heard from patients, both dialysis and non-dialysis patients, about the need. And I think, you know, I know the FDA heard that as well and sees the need here also, so we're encouraged by our physicians.
spk06: Great. Thank you. Just another quick one from us. Have your, you know, commercialization plans materially changed? I understand you mentioned there's a larger opportunity out there now following the adcom. Have you made changes to your commercialization plan following that adcom meeting?
spk11: So, yeah, I mean, I guess in fairness, the opportunity is still the same. The market's still the same. We just have the opportunity to be first, and I think Dell and his team are pretty excited about that.
spk09: Yeah, we're really excited about it. I think the opportunity to be first and to be a leader in the marketplace gives us the opportunity, as mentioned, to really differentiate ourselves from the other HIF products as well as the ESAs, and to really help build that unmet need in the marketplace, as John talked about. So when you look at our overall commercialization plan, I don't think it's materially changed in the customers that we're working with in the marketplace, how we're engaging with Erixia today and how we plan to engage with Vatadustat upon approval. But we certainly recognize the opportunity to be the market lead as the first product to market potentially, and we're really excited about it.
spk11: And our relationship with V4 still has a lot of power for us also. As we've said, that's what really moves the needle quickly for us in the dialysis community. So Yeah, it's an exciting time. The opportunity to potentially be first to market is kind of a game changer for us. Thank you. Thank you.
spk03: Thank you. Our next question comes from the line of Eric Joseph, JP Morgan. Your line is open.
spk02: Hi, morning. Thanks for taking the questions. Assuming approval in both the non-dialysis and dialysis settings, Can you just unpack a little bit more how the reimbursement and economic constraints differ between the two segments and what that could mean for net pricing with Vita-Dustat in the two segments? And then perhaps separately, is Tdapa eligibility something that applies in a non-dialysis setting? Thanks.
spk11: Eric, thanks so much for the questions. They are two very different markets and different from a reimbursement standpoint, and I'll ask Del to walk through that.
spk09: So, I think starting with the, at the highest level, when you look at the dialysis opportunity, it's really contract-driven at the dialysis organization level. And the TED-AFA payment, which we believe we're eligible for, you know, is intended to drive use of new and innovative products that launch. And we think the rule is clear here and that will be covered for the patients that are part of the PPS bundle. In addition to that, there are other payment groups, but still that drive largely through the dialysis contract. So that's if you look at the dialysis business. If you move over and look at the NDD population, it's going to be a more typical contracting with payers and PBMs for coverage of the product. And, you know, we anticipate, given the unmet need in the space, that we will be able to obtain coverage for our product and drive coverage and get access and reimbursement that will be important moving forward. And obviously, you know, that's the key focus for us right now. Yep.
spk11: Yeah, and again, I mean, as we said up front, I always want to make sure we're telling people that we remain cautious on the NDD indication given the miss on MACE, but overall, but as I also said, we still feel quite confident in the data that we've submitted. And we'll be ready to launch in both areas. And I think you had a second question. Was there?
spk09: No, that was it? No. KidAPA eligibility would not apply to the non-dialysis population.
spk02: Got it. Okay. That's very helpful. Thanks for taking the questions. Thanks, Eric.
spk03: Thank you. Our next question comes from the line of Ed Arcee with HC Wainwright. Your line is open.
spk08: Great. Thanks for taking my questions. Three for me. First, You know, on the line of discussion around differentiation here, we talked about the adverse events that were highlighted at the recent ADCOM. I'm wondering if there's any quantitative data around the EPO overshoots and, you know, given the focus on the rapid rise there. if there's any, you know, data specifically that you can point to either in the New England Journal or is that something that perhaps you could look to or we could look to for ASN as a, you know, potential follow-on publication or analysis. That's one. Second is given the recent CRL on Tanapanor, in hyperphosphatemia. I'm just wondering your impressions from clinicians on the impact on the overall space there and potentially the impact to Eryxia's growth going forward. And then finally, a question on the regulatory milestones. I know We went over this in the prepared remarks, but I missed some of the numbers. So if you could repeat that, that would be helpful. Thank you so much.
spk11: Ed, thanks so much for your questions. So first on the AEs. We haven't published the data on EPO overshoots. What we said is that there were clearly fewer overshoots of Vatadustat versus Darvopoetin. That certainly could be the basis for a publication later, and we do think it will be an important differentiator, so I think you were right to... to bring that up.
spk10: And that is all mentioned in the New England Journal of Publications.
spk11: Yeah, sorry, Kristen. Yeah, it's mentioned. The data just doesn't accompany it at this point, but would certainly be an interesting publication on its own. And then your second question was on the CRL for canapinor and the impact on that. You know, as a purpose-driven company that's focused on patient care, you know, anything that actually can help patients achieve a lower phosphorus level and manage hyperphosphatemia I think would be welcome. So from that perspective, I guess it's disappointing. You know, we never really looked at it as a competitor per se because we really thought that, you know, that would be utilization of the products together. But I don't think we see much impact. Other than that, we believe in Oryxia's growth potential that will grow this year. Dale, do you want to add comments on that?
spk09: No, I think there is a tremendous amount of room for improvement in patient outcomes, and so certainly from an impact perspective in the space. But as John said, we believe that Oryxia is an important part. for more than six years, and we have a lot of real-world efficacy and safety data that supports that. So from our point of view, it hasn't really changed our view of what we hope to accomplish with Arixia, and we're going to continue to execute against our commercial plans to drive net revenue growth moving forward.
spk11: Thanks, Del. And, Dave, I think it was you.
spk07: Yeah, so I can clarify the regulatory milestones. So in the U.S., for a first HIF approved in dialysis, the milestone would be $15 million. And if we are the first HIF approved in non-dialysis, that would be $50 million.
spk08: Great. Thanks so much. Appreciate it.
spk03: Thanks, Ed.
spk08: Thanks, Ed.
spk03: Thank you. Ladies and gentlemen, that concludes our Q&A session. I would now like to turn the call back over to Mr. Butler for closing remarks.
spk11: Thanks, Tawanda, and thanks to everyone who joined us for the call today. As I mentioned, this is a very exciting time for Akibia. The potential to be first in class is really energizing the company, and we look forward to continuing to to update you on our progress as we move through the year. Thank you.
spk03: Ladies and gentlemen, this concludes today's conference call. Thank you for your participation. You may now disconnect.
