Good morning, ladies and gentlemen. Thank you for standing by, and welcome to the Apellis Pharmaceuticals Third Quarter 2025 Earnings Conference Call. Please be advised that today's conference is being recorded. I would now like to turn the call over to Eva Stroynowski, Head of Investor Relations. Please go ahead.

Good morning, and thank you for joining us to discuss the Apellis' Third Quarter 2025 Financial Results. With me on the call are Co-Founder and Chief Executive Officer, Dr. Cedric Francois; Executive Vice President of Commercial, David Acheson; Chief Medical Officer, Dr. Caroline Baumal; and Chief Financial Officer, Tim Sullivan. Before we begin, let me point out that we will be making forward-looking statements that are based on our current expectations and beliefs. These statements are subject to certain risks and uncertainties, and actual results may differ materially. I encourage you to consult the risk factors discussed in our SEC filings for additional detail. Now I'll turn the call over to Cedric.

Thank you, Eva. Before diving into our third quarter results and portfolio progress, I want to briefly highlight the unmet need that Apellis set outs to tackle and why we are uniquely positioned to address that challenge. Apellis is a commercial stage biotech company targeting the overactivation of the complement system, an innate defense mechanism in the immune system that protects the body from acute infection and illness. However, when complement is chronically unregulated, there can be a devastating effect on one's health, driving a broad range of serious often life-threatening diseases. Most approved complement-targeted therapeutics inhibit at C5, a downstream protein in the complement cascade. By only blocking this target, C5 inhibitors do not affect the upstream activity that drives inflammation and tissue damage. Similarly, inhibitors of Factor B act earlier in the cascade and narrowly, reducing alternative pathway amplification but allowing classical and lectin pathway activity to persist, leaving some disease activity unchecked. Apellis' science is founded on a simple but powerful idea to address complement-driven diseases at their source by targeting C3, the central hub where all complement pathways converge. By doing this, we take a fundamentally different approach that enables comprehensive disease control at root cause. For decades, the prevailing view was that C3 could not be effectively modulated because of its central role in immune defense. Apellis solved this challenge by engineering pegcetacoplan, a first-in-class C3 inhibitor that controls overactive complement while preserving essential immune function. The result is both a technological feat in drug design and a transformative clinical advancement for patients. This vision is what sets Apellis apart. We have mastered our core technology and redefined complement therapeutics. The scientific advantage underpins our success to date. Having now translated decades of innovation into 2 approved medicines across 4 serious diseases, Apellis is a…

Thank you, Cedric, and good morning, everyone. I'll start with EMPAVELI and the recent approval in C3G and primary IC-MPGN. We are now 2 months into the launch, and I'm very pleased with our progress so far. Feedback from the nephrology community has been outstanding, and we are carrying that momentum into Q4. In the U.S., we estimate there are approximately 5,000 C3G and primary IC-MPGN patients. Notably, EMPAVELI's broad label makes it the first and only treatment approved for a comprehensive list of patient populations, including adult patients with C3G, adult patients with IC-MPGN, pediatric patients with C3G, primary IC-MPGN patients aged 12 years and older and patients with post-transplant C3G disease recurrence. EMPAVELI is the only approved therapy for approximately 2/3 of this 5,000 patient population, and we believe it offers highly differentiated efficacy for the other 1/3 where patients have an alternative. Together, the broad label and the strong clinical data position the launch of EMPAVELI for the long-term success. For the first time, patients can be treated with a first-in-class C3 targeting therapy and the only complement therapy that has demonstrated its ability to preserve kidney function by controlling all 3 markers of these diseases, including proteinuria reduction, eGFR stabilization and substantial clearance of C3 deposits. EMPAVELI is delivered through our compact single-use on-body auto-injector. Patients can self-administer in the comfort of their own home without ever seeing a needle. Early feedback from the market has been exceptionally positive, highlighting its ease of use and the convenience of the twice-weekly dosing. The PK profile of EMPAVELI allows patients the flexibility to take treatment on their own terms, avoiding twice daily dosing required by the oral alternative. Ahead of the launch, we scaled our field-based teams to approximately 100 people, ensuring coverage of every U.S. nephrologist managing…

Thanks, David. Let me start with SYFOVRE and geographic atrophy. As the only approved drug that binds to C3, the central protein of the complement cascade, SYFOVRE potently inhibits the damaging downstream effects of complement overactivation, forming the basis of its strong clinical profile. Patients with GA are on an irreversible path to blindness. As Cedric and David mentioned, there is ample opportunity to advance the understanding of GA within the treatment community and to instill the urgency to treat patients early to save retina tissue. To support this, we are developing artificial intelligence tools that will help physicians gain a better understanding of what GA patients experience as well as the benefit of treatment with SYFOVRE. We are also working to provide more convenient administration through the development of a prefilled syringe. We believe that both of these key initiatives will broaden the prescriber universe within the overall GA market and drive higher utilization of SYFOVRE over time. Turning now to EMPAVELI in C3G and primary IC-MPGN. The treatment community's response to the recent approval has been incredibly positive, and we are confident that it will be the preferred treatment option for these patients. We're excited to share 7 abstracts at next week's American Society of Nephrology meeting, further demonstrating EMPAVELI's profound and durable benefit and underscoring our commitment to the rare nephrology community. Building on this momentum, we are expanding EMPAVELI's development into 2 other rare kidney diseases, primary focal segmental glomerulosclerosis, or FSGS, and delayed graft function, or DGF. Similar to C3G, FSGS is a rare kidney disease that progresses to kidney failure within 5 to 10 years for about half of patients. DGF is a complication in kidney transplantation that negatively affects the long-term survival of the kidney and the overall patient outcomes. The complement pathway plays a significant role in both diseases, and there are currently no FDA-approved therapies for either. We are well underway with our planning activities and expect to initiate pivotal trials in FSGS and DGF by the end of the year. With that, I'll now turn the call over to Tim for an update of the financials.

Thank you, Caroline. Total revenue for the third quarter was $459 million, including the $275 million upfront payment from Sobi in connection with the Aspaveli royalty purchase agreement. SYFOVRE net product revenue for the quarter was $151 million. We delivered approximately 101,000 doses of SYFOVRE in the quarter, including 86,000 commercial doses and 15,000 free goods doses. In line with our expectations, we saw a 4% sequential growth in overall total injection demand during the third quarter, driven predominantly by free goods. While we are encouraged by the continued growth in total injections as a leading indicator of demand, we did see an approximate $15 million headwind to our reported revenue due to the elevated use of free goods, which was slightly higher than our expectations. Through the first 3 quarters of the year, we estimate that free drug has been a nearly $40 million headwind to SYFOVRE revenue. Looking ahead to the fourth quarter, we continue to expect modest SYFOVRE total injection growth within the low to mid-single-digit range. Turning to gross to net dynamics. Adjustments during the third quarter for SYFOVRE remained within the low to mid-20% range, consistent with our guidance through 2025. As we move into Q4, we expect gross to net to trend slightly above the prior range. This reflects the normal step-wise pattern of gross to nets over time with modest degradation and some quarter-to-quarter movement that's typical in the buy-and-bill market. Importantly, this reflects expected dynamics rather than a structural shift, and we remain confident in our pricing and access position heading into 2026. From a channel perspective, we anticipate a modest channel build during the fourth quarter, consistent with seasonal patterns expected at year-end. That said, we continue to target stable inventory levels quarter-over-quarter, and we'll provide further commentary during our year-end…

Thank you, Tim. We have made important progress in 2025 to date. We achieved our third approval in just 4 years, bringing a first-in-class C3 treatment option to people living with C3G and primary IC-MPGN, many of whom had previously been living without any available options. Early feedback across the patient and nephrology communities has been enthusiastic, reflecting recognition of EMPAVELI's compelling efficacy profile and its value as a new treatment option. Additionally, SYFOVRE continues its market leadership and delivers a durable, meaningful revenue stream with opportunities for renewed growth over the long term. Combined with the cash from our Sobi deal in June, we have made steady progress on our path towards profitability. We look forward to building off the solid foundation we have laid for ourselves in the fourth quarter and into 2026. And with that, I'll turn the call over to the operator for questions and answers.

[Operator Instructions] Our first question comes from the line of Jon Miller with Evercore ISI.

Congrats on the progress and a strong C3G launch. I guess I'll ask my question -- I'll ask my question about that. Do you still expect past this first bolus of patients that you were talking about that kidney is going to be a distributed or slow indication -- set of indications to penetrate? I think this has been your commentary and the competitors' commentary in the past. Do you expect that to continue? Or is your strong penetration into these top practices indicative of the launch could be more rapid than people expect?

Thank you, Jon. Great to hear you. And I will hand that question over to David.

Jon, thanks for the question. Appreciate it. So first of all, we're really excited about where we are with the launch for EMPAVELI and C3G and primary IC-MPGN. The team has done a great job. And I do suspect as we get through the end of this year that the bolus that we had talked about will be through that, and you'll see steady, consistent growth going into next year. That's our expectation.

Our next question comes from the line of Anupam Rama with JPMorgan.

Just a quick one on SYFOVRE and on sampling. I think samples are on the higher end of this 10% to 15% range that we've all previously talked about. Should we expect this to now be more stabilized? Or is there a chance that this continues to creep up as you expand the market?

Anupam, great hearing you. Again, I'm going to hand that over to David.

Anupam, thanks for the question. So a couple of things real quick. We definitely review where we are with samples in the PAP program or free goods consistently to make sure that programs are being utilized the way that we want them to be. Also, though, we are, as you know, as a company, very in tune to making sure patients have access to products. So as things continue to grow, we'll have programs available for patients.

Our next question comes from the line of Steve Seedhouse with Cantor.

Just wanted to ask a few specifics on C3G. So first, can you break out just of the 150-odd patients, how many are C3G, how many are IC-MPGN pre- versus post-transplant, adult versus adolescent? And then also, do you know if anyone has switched from Fabhalta to EMPAVELI? And do you have a sense of your market share in C3G, just how many patients are on Fabhalta versus EMPAVELI?

Thank you, Steve. Great question. This is David. So you're right, we have 152 start forms, roughly 50 of those came through our EAP program. Consistently to label, we've seen start forms come through across the broad label, which is positive and for both indications. And we are seeing Fabhalta switches as a result of the information we've gotten from physicians as a result of our efficacy, in some cases, some tolerability and the ability for them to dose twice weekly with EMPAVELI versus twice daily with the competitive product.

[Operator Instructions] Our next question comes from the line of Yigal Nochomovitz with Citigroup.

So this is also a specific question on the launch. I think, David, you mentioned that 50 of the patients are in the process of converting to commercial drug. These are the ones rolling over from the clinical trials. It's just not clear. Are those actually on drug at this point? Are they still in process? And then the incremental other 102, could you just comment on what fraction of those have started EMPAVELI and approximately how long they've been on the drug since the end of July?

Yigal, thank you for the question. So you're correct. There's 50, roughly 50 patients on EAP. Our goal is to make sure all of them make it to commercial product by the end of the year. And of the rest that have come in for new start forms, we are still working through the process with many of them. Remember, it takes 4 to 6 weeks for those patients to typically get from start to finish and get product. And that process is also being worked out as we move through the end of the year.

Our next question comes from the line of Salveen Richter with Goldman Sachs.

This is Elizabeth on for Salveen. Just one from us on that 4- to 6-week time frame from start to finish of getting product of EMPAVELI to treatment. When do you think we could start to see kind of an acceleration there? And what do you think that could normalize as?

Yes. Thank you very much, Elizabeth. So a couple of things to keep in mind. That's typical for most -- rare disease launches, in particular, where you have a REMS and vaccinations, and the start form that has to go in from a physician. The other thing that we're continuing to work through is the policies that are being written at the payer, which also takes some work early on in the process to make sure that, that transition from 4 to 6 weeks comes down to less than that period. So we're working through that now, and we'll have details as we move forward.

Our next question comes from the line of Akash Tewari with Jefferies.

This is Kathy on for Akash. So SYFOVRE rev stayed flat at $161 million quarter-over-quarter and induction growth was 4%. So one, do you see this as a floor for SYFOVRE before other components like long-term efficacy data or PFS come into play? And then two, when can we assume a return to growth for SYFOVRE? Or do you think it stays at this level given you're not assuming patient funding gets resolved near term?

Thank you, Kathy. So this is Tim. So from a growth perspective, this quarter, we feel very good about the underlying demand growth of 4%. As we mentioned in the prepared remarks, the bulk of those -- that increase in demand came from free goods. So that was a headwind that we've been experiencing for the last 3 quarters or so, and it's -- the headwind has amounted to approximately $40 million over the course of the last 3 quarters. Now over the long term, beyond these short-term dynamics, as Cedric and Caroline mentioned in their prepared remarks, we have a lot of compelling opportunities to reinvigorate SYFOVRE's growth. Those include the prefilled syringe, among others, and we'll get more visibility to you on those at the beginning of the year.

Our next question comes from the line of Colleen Kusy with Baird.

Congrats on the progress. You spoke to some learnings of prescribers' habits in C3G and IC-MPGN at this early stage of launch. Can you elaborate on that a little bit and what the implications are for this launch?

Yes. This is David. Thank you, and I'll hand it over to Caroline, too, for some comments on the medical side. I can tell you that we've been very pleased with the fact that we have a very open label. And we've seen patients come through that are aligned to all of the indications -- for both indications in the label, which is very positive. What we're learning now is we're making sure that we get through the process and education with the top [indiscernible] accounts and also make sure that we are continuing to canvas and have the conversations with all of the accounts beyond that. So it's a new indication and a new product for folks, and they're learning how to adjust to it, but we're excited about the launch so far.

And what we've been hearing from physicians is that they are excited about our data, the robustness of it, the reduction in proteinuria and our 52-week results will be presented at the American Society of Nephrology amongst other abstracts that we have highlighting the reductions in proteinuria.

Yes. Maybe one last thing here from me. This is Cedric. It's been really gratifying to see how well we kind of were prepared and understand the landscape. We're very happy with the demographics that we have calculated, the ramp forecast we've created. So it's gratifying to see the results from clinical trials translate in the real world and the way it is.

Our next question comes from the line of Ellen Horste with TD Cowen.

I'm on for Phil this morning. Congrats on the quarter. Just one question from us. On SYFOVRE, has there been any progress with the Good Days co-pay assistance charity? Is there any visibility on when and if it can be funded to FSGS patients?

Thank you for the question. This is Tim. So there has been some progress in the sense that we understand that the largest of these groups is open for existing patients, but unfortunately, not for new patients, and you can check that on the website. But as far as we know and as far as we're -- as far as our guidance that we gave in terms of this quarter, we don't expect anything to change with respect to the patient assistance organization.

Our next question comes from the line of Jade Momen with Stifel.

This is [Diane on for Annabel]. Two questions. The first one is for C3G, IC-MPGN. For that 1/3 shared market with Fabhalta, how do you expect prescriber -- how do you expect that market to bifurcate? What type of patients would -- are physicians starting Fabhalta in? And what type of patients would be preferred for EMPAVELI ?

Yes. Thank you for that question. This is Cedric. So I think that, look, the efficacy profile that was established in the VALIANT trial across all of the patient populations that we have tested and that we've spoken about, that is really what stands out there. So this is something that we believe is going to be really important in a segment of physicians that cares deeply about differentiated efficacy. So yes, I think we have -- with the broad label that we have, we have an opportunity to really kind of go through segment by segment. We've talked before about the fact that post-transplant patients are a particularly interesting group for obvious reasons. Most transplanted patients will relapse. Now it takes a little bit of time to get on protocols, et cetera, but that's a very exciting group of patients that we're looking forward to being able to help. And then, of course, patients that are advanced at risk of going into end-stage renal disease. And then the fact that we have pediatrics in our label as well and be able to offer something to patients 12 years to 18 years is very attractive to the nephrology community as well.

And I got one more on SYFOVRE. It's been on the market for a couple of years now. And if you go by the patterns in wet AMD, we might start to see patients drop off at this stage. What are you seeing as far as persistence on treatment?

Compliant.

Thank you for the question. Well, with our every other month dosing, which is very in line with anti-VEGF treatments, we're hearing from our physicians that patients are being compliant with treatment, and there will be some long-term data coming out from our open-label extension next year.

Our next question comes from the line of Lachlan Hanbury-Brown with William Blair.

I guess one on SYFOVRE. I noticed the new patient share ticked down a few points this quarter. I was wondering if there's any underlying dynamic that changed in the quarter that drove that? Or is that just sort of noise fluctuating a few percentage points, and it's kind of reached a point of stability here?

Yes. Great. Thanks for the question. This is David. So first of all, we're very confident in where we are competitively and just a reminder, we're 52% on NBRxs and over 60%, we continue to hold and have held for TRxs. You're exactly right. What sometimes you'll see is a fluctuation in NBRxs up or down and -- but we're confident in the consistent numbers that we've seen and reporting today.

Our next question comes from the line of Derek Archila with Wells Fargo.

Maybe just 2 from us. First on SYFOVRE. I guess how do you think about prefilled syringe, the checks that we've done on that, it seems like docs would be pretty enthusiastic. So when could that be made available? And how do you think that changes the growth trajectory? Is it more shifting share or expanding the market? And then I didn't know if I joined late, so just in terms of EMPAVELI start forms, any comments on trends post the quarter?

Derek, great hearing you. Thank you so much. Yes, the prefilled syringe is something that is really important in the context of the retina physicians. It improves the flow in their practices, makes it easier to handle the workload. We have been working on a prefilled syringe. That prefilled syringe is currently being tested in the clinic. We're not guiding on time as to when it will actually be available for competitive reasons. But the quality of the syringe that we have has met the high expectations that we've had and super excited about going to market with that. I think it's also worth mentioning here that the -- within kind of the type of physicians that treat patients with geographic atrophy, there are a lot of physicians that occasionally use SYFOVRE, not on a regular basis. Those are physicians that I suspect are going to be excited about kind of moving towards a more routine involvement of GA patients into their practices. But even for those physicians that have not yet embraced SYFOVRE as a treatment for their patients, we know that many of them are waiting for the prefilled syringe to start treating this terrible disease. I don't know, Caroline, if you want to add something?

Well, as a retina physician, I will say that it really increases convenience, consistency and safety to have a prefilled syringe. And the requirements are very high for quality, and I'm really, really pleased with where we're headed with this. There was another part to the question.

So Derek, -- just the last part of that question, thank you again. So from a launch perspective, obviously, we feel great. Beyond the guidance that we gave in terms of the start forms for the prepared remarks, I don't think we're not guiding any further than that, but we're happy to look forward to giving you an update at the year-end call.

Our next question comes from the line of Biren Amin with Pipa Sandler.

This morning, Apellis just revised IZERVAY sales guidance downward by $200 million. And so they're clearly seeing headwinds in GA market growth. Given that data point and your low to mid-single injection growth that you project, do you feel it's due to undertreatment? And what shifts that dynamic with retina physicians?

Yes. I mean so I'll start. So I'll just confirm what you're saying, which is that we do see a significant headwind for these patients who are trying to get treated and want to get treated, but can't afford it. So it's had a huge impact on the market in general. And at least our discussions with retinal specialists suggest that many of them are not treating GA patients or not even having the conversation they should be having with GA patients because this has created a logistical as well as a financial headwind. I'm not sure. I hope that answers your question.

I think what can shift the dynamics with physicians also are multiple things that we're working on at Apellis. We're the science company. We have robust data. We're working on educating physicians using artificial intelligence, which they can also use for patients. We're working on a prefilled syringe, and we have multiple new things coming forward to impact physicians and patients.

Our next question comes from the line of Judah Frommer with Morgan Stanley.

Maybe just a couple of follow-ups. I guess on patient start forms for C3G and IC-MPGN, can you comment on just how they came in versus internal expectations? It sounds like they came in reasonably well. And then on just the sampling for SYFOVRE, any commentary you can make on how much of that is self-driven versus competitive dynamics on sampling?

Yes. Thank you so much. For the expectations with C3G and IC-MPGN, as I outlined earlier, this is very much in line with what we had expected. We have high expectations. We have -- we also feel very good about the demographics that we have established. That number of 5,000, we believe, is a robust conservative estimate for the number of patients that are out there and could be helped with our product. Then your question on SYFOVIE I'm sorry, but you are breaking up...

I can answer. It's on the samples in the free goods. So your question was, is there a competitive dynamic? I don't think that's necessarily the case. What we do know is if someone is reaching for a free good, that's true demand. It's a patient that wants to be treated. It's a physician that wants to treat the patient. And we have those programs in place and monitor them regularly to make sure that they're within the guidelines that we want to have followed, but they're accessible because patients that want to go on treatment, we believe, should be able to do that.

Our next question comes from the line of Ryan Deschner with Raymond James.

Can you remind us when the actual date EMPAVELI was first made available to patients for the C3G, IC-MPGN launch? And then also, do you have an update on the rough time line for a top line readout from the Phase II study for SYFOVRE and APL-3007?

This is David. I'll answer the first part of the question. We launched the product in the week of July 28. And I'll hand the other portion of the question over on 3007 to Cedric?

Yes. So thank you for that question. So the trial is enrolling. We're very excited about this trial. As a reminder, with 3007, what we do is combine SYFOVRE with a subcutaneous injection that is an siRNA product, which brings down the systemic levels of C3 by approximately 90%. And the objective there is to go from every 2 months to every 3-month dosing and to then obviously, of course, see an outsized effect on the efficacy side. We're not guiding in terms of when that study will be completed. It's currently enrolling and has a 1-year endpoint readout.

Our next question comes from the line of Douglas Tsao with H.C. Wainwright.

Tim, I think it was you that sort of mentioned that there's an issue with some practices sort of just having with a lack of co-pay support sort of a backlog or sort of operational challenges with practices if -- because they're not able to easily put patients on treatment. Is that in terms of just the headache within the practice in terms of just the time it takes to sort of adjudicate benefits and follow that patient? Or is it just the sort of patient having an unrealistic expectation of starting treatment and then having themselves put off and sort of having to deal with the frustration on that side?

Yes. It's just -- it's a very -- it's really a very complicated situation for the physicians as well as for the patients, right? Kind of figuring out who can afford co-pay, who cannot. I mean there's a lot that goes into it. There's a lot of chair time that is lost by the physician in that process. And as Tim outlined earlier, what we've seen this year is, of course, kind of, a lot of slowdown that was driven by these dynamics, not just on the GI side, also on the wet AMD side, where a lot of practices have temporarily paused even bringing on new patients to avoid having those discussions. So these are all things that are headwinds that we'll have to find a new place of settlement but we are working hard on it. We can help practices with availability and access, of course, but the foundation is something that we -- that is something that we're separated from, of course.

I'll also add that it particularly affects GA patients because there is a generic alternative in the wet AMD space. There is no generic alternative in the GA space.

And if I can, on the kidney launch, I'm just curious, I know obviously, something that you sort of -- people have been wondering about in terms of the identification of patients with C3G and IC-MPGN since it does require a biopsy. Have you seen evidence that now there is an available treatment like EMPAVELI or such an efficacious treatment that clinicians are biopsying more regularly or more aggressively than they were in the past?

Well, that typically happens when there's a new treatment available for something when there was no previous treatment that there are patients that come out of the woodwork and clinicians are also more motivated to make the diagnosis so they can more effectively treat this disease, which does ultimately end in end-stage renal failure.

Our next question comes from the line of Graig Suvannavejh with Mizuho.

Congrats on the progress. Just wanted to go back to EMPAVELI. I might have missed it before, but anyway you can provide a sense of breakout in terms of the revenue and what came from PNH and what came from the new rare kidney indications and how the 152 in new patient start forms, how that might have contributed to whatever contribution there was to EMPAVELI revenue from the new rare kidney indications.

Graig, thank you for the questions. This is Tim. Yes. So you can look at our PNH revenue for the last few quarters. Last quarter, we reported, I think, $20.3 million in EMPAVELI revenue. And that market has been relatively static. So I think from the perspective of revenue, you can maybe back out a little bit there and look at the fact that we probably are also putting a little bit into inventory as a distributor. So on a combined basis, it's -- we don't break out that in terms of revenue, and we don't plan to break that out because it is hard for us to do that. And then from a -- can you repeat the second part of the question? I apologize.

Yes. Just for -- if we do and thanks for that clarity on maybe assuming $20 million-ish or so from PNH and then maybe some inventory build, but whatever the balance is for EMPAVELI revenue in the quarter from the new rare kidney indications. Just trying to get a sense of if you did provide us with $152 million in terms of the patient start forms, how much of that is kind of translating into that balance of revenue specifically in rare kidney? And just trying to get a sense of what fourth quarter might look like, understanding that you're not providing sales guidance per se.

Yes. We're not providing sales guidance. We did give you some guidance on sort of an expectation around start forms for the year-end, which was $225 million. So look, I think the way to think about this probably is looking at the time to getting on drug from start form to getting on drug is approximately 4 to 6 weeks, and I would just work backwards from that.

Our next question comes from the line of Lisa Walter with RBC.

Congrats on the kidney launch. I was just wondering if you could provide us any color on the pivotal trial design for FSGS and DGF.

Thank you so much. So these trials have just started. We're not providing details beyond what's available on clinicaltrials.gov. But we're really excited about the opportunity that we have in FSGS and DGF. FSGS, as a reminder, affects about 13,000 patients in the U.S., similar in terms of severity to the patient and the patient's kidney to what we see with C3G and IC-MPGN. And we're looking forward to hopefully having a treatment available for these patients. With delayed graft function, we are looking into a 3-month treatment with EMPAVELI to protect the kidneys that typically come from diseased donors, of which there are 21,000 per year. And about probably 30% of those patients will suffer from that so-called delayed graft function, which is an increase in creatinine in the week post-transplant.

Ladies and gentlemen, we have time for one last question, and that will come from the line of -- it's a follow-up question from the line of Yigal Nochomovitz with Citigroup.

Just one quick follow-up, please, on the prefilled syringe. Cedric or Tim or David, I'm just wondering, is that going to be offered also as samples? Or will it only be -- will be restricted to just commercial drug for the prefilled syringe?

Thanks. This is David. So we will launch with commercial product. And then over time, we'll have samples available as we get into the launch.

I would like to turn the call back over to Cedric for closing remarks.

Thank you so much, and thank you, everybody, for your thoughtful questions. This concludes the Apellis third quarter earnings call, and I hope you all have a wonderful rest of the day.

Ladies and gentlemen, that concludes today's conference. Thank you for your participation. You may now disconnect.
