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

Good morning, and thank you for joining us to discuss Apellis' Fourth Quarter and Full Year 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, and thank you all for joining us this morning. Before turning to our fourth quarter results, I'd like to briefly reflect on the progress Apellis made over the course of 2025. It was a year of disciplined execution and foundation building for our company. We strengthened our commercial franchises, advanced key programs across our pipeline and continued to demonstrate the value of our differentiated C3 approach, all while maintaining a strong balance sheet and a clear focus on long-term value creation. These foundations position us well as we move ahead with clear priorities centered on execution, growth and unlocking the next set of value-creating inflection points for Apellis. At our core, Apellis is a company focused on complement biology, specifically targeting C3, the central hub of the complement cascade. By intervening at this central point where all complement pathways converge, we take a fundamentally different approach that enables comprehensive disease control at the root cause while preserving essential immune function. This strategy continues to differentiate us scientifically and commercially and positions us to address a broad range of serious complement-driven diseases. Our 2026 focus remains anchored in our 3 strategic pillars. First, strengthening SYFOVRE's leadership in geographic atrophy. Second, driving growth with EMPAVELI across rare kidney diseases. And third, advancing an innovative pipeline that underpins our next wave of growth. Starting with SYFOVRE. SYFOVRE continues to be a resilient and durable business. In 2025, we delivered steady growth in total injections, and we expect SYFOVRE to remain a stable and meaningful revenue stream through 2026. Last month, co-pay assistance programs at third-party organizations began reopening to new patients. While we do not have visibility into how activity may ramp over time, we are encouraged that patients may be able to gain access to treatment. Looking ahead, we…

Thank you, Cedric, and good morning, everyone. I'll begin with SYFOVRE. As Cedric highlighted, 2025 reinforced that SYFOVRE is a resilient and durable business. While full year revenue was modestly down compared to 2024, largely due to elevated use of free goods, the underlying demand remains strong with total injections growing approximately 17% year-over-year. SYFOVRE continues to lead the GA market. Physicians and patients value its differentiated profile, including robust efficacy and the flexibility of dosing as few as 6 times per year. Payer coverage remains strong with preferred status across a broad range of plans. As the GA market continues to evolve, we see meaningful opportunity for SYFOVRE and are focused on 3 priorities to support continued expansion and long-term growth. First, sharpening our field engagement through physician segmentation, refined messaging and a greater emphasis on early career retina specialists. Second, reinforcing our data leadership in GA. SYFOVRE is supported by the most extensive clinical and real-world evidence base in the category, anchored by 5-year GALE data; and third, advancing innovation with a best-in-class prefilled syringe and OCT-F. Together, these initiatives are foundational to supporting broader growth in 2027 and beyond. Turning to EMPAVELI. We are very pleased with the progress in C3G and primary IC-MPGN launch with early uptake fully consistent with our expectations. Following its first full quarter post launch, EMPAVELI achieved more than 5% market penetration. This level of early adoption is particularly notable in nephrology, a specialty known for conservative prescribing behavior and high evidentiary thresholds. As of year-end 2025, we received 267 cumulative patient start forms, reflecting strong early demand and a growing patient pipeline. Demand is being driven by broad engagement across the nephrology community and supported by favorable payer access with 95% of published policies reimbursing to label or with minimal restrictions.…

Thanks, David. I'll begin with SYFOVRE. As the only approved therapy that targets C3, SYFOVRE addresses the central biology driving geographic atrophy, which continues to differentiate its clinical profile. In the fourth quarter, we announced new 5-year data from a post-hoc analysis of the GALE extension study, which showed that SYFOVRE delayed progression of geographic atrophy by approximately 1.5 years in patients with nonsubfoveal GA when compared to sham or projected sham. We look forward to presenting the full 5-year data set at the Macula Society later this week as one of our 8 oral presentations at the conference. Looking ahead, we are advancing 2 initiatives designed to support clinical decision-making and real-world use. First, our prefilled syringe intended to improve efficiency in retina practices. The clinical study is complete, and we are working toward a regulatory submission in the first half of this year. Second, we continue to make important progress with functional OCT, our AI-enabled approach to visualizing functional benefit in GA. We recently shared data at the Angiogenesis meeting earlier this month and plan to make the tool available for research use in retina practices in the second half of this year. In parallel, we continue to advance the Phase II study of SYFOVRE in combination with APL-3007 as a next-generation approach designed to more comprehensively block complement activity in the retina and choroid. We expect to share top line data in 2027. Now turning to EMPAVELI in C3G and primary IC-MPGN. Physician feedback and the recent New England Journal of Medicine publication continue to reinforce EMPAVELI's differentiated profile. As the only C3 targeting therapy, EMPAVELI has demonstrated the trifecta of efficacy outcomes with direct clearance of C3 deposits translating into reduced proteinuria and stabilization of kidney function. These data reinforce our confidence in EMPAVELI's mechanism and its potential to redefine treatments in complement-mediated kidney disease. We also recently initiated pivotal trials with EMPAVELI in FSGS and DGF, 2 additional high unmet need kidney indications. Both conditions are strongly linked to complement activation and currently have no FDA-approved therapies. Finally, I'll briefly touch on APL-9099, our FcRn program. This first-in-class base editing approach is designed to reduce IgG levels while preserving albumin, which we believe addresses important limitations of existing FcRn therapies. We expect to submit an IND in the second half of this year and look forward to sharing more details as the program progresses. With that, I'll now turn the call over to Tim.

Thank you, Caroline. I'll now walk through our financial results. Additional details are included in this morning's press release. Total revenue for the fourth quarter and full year 2025 was $200 million and $1 billion, respectively. As a reminder, full year 2025 revenue includes the onetime $275 million upfront payment from the Sobi royalty repurchase agreement. We reported SYFOVRE net product revenue of $155 million for the fourth quarter and $587 million for the full year 2025. During the fourth quarter, we delivered approximately 102,000 SYFOVRE doses to physician offices, including approximately 89,000 commercial doses and 13,000 free goods doses. As previously discussed, reported revenue was meaningfully impacted due to elevated free goods utilization through 2025. Looking ahead, we remain committed to supporting patient access while recognizing that free goods utilization may evolve over time as third-party programs resume activity. Turning to gross to net. SYFOVRE adjustments in the fourth quarter trended just above the mid-20% range. In 2026, we expect gross to net to be in the high 20% range, reflecting the normal step-wise evolution of the buy-and-bill market. Importantly, based on our current pricing strategy, we expect net price to remain relatively stable through 2026, and we remain confident in our access position. As we exited 2025, we took a disciplined approach to inventory management, and we are comfortable with the current channel levels. We, therefore, expect a modest inventory reduction in the first quarter alongside typical seasonal dynamics, including Medicare reverifications. Overall, SYFOVRE remains a meaningful and durable foundation for Apellis. In 2026, we are focused on disciplined execution while advancing initiatives that position the business for renewed growth in 2027 and beyond. Moving to EMPAVELI. We reported U.S. net product revenue of $35 million for the fourth quarter and $102 million for the full year 2025.…

Thank you, Tim. As we move through 2026, our priorities are clear. We are focused on disciplined execution across our commercial portfolio, advancing initiatives that support long-term growth and continuing to deliver meaningful impact for patients. EMPAVELI is gaining traction in C3G and primary IC-MPGN, while SYFOVRE provides a durable foundation as we position the franchise for its next phase of growth. Supported by a strong balance sheet and financial rigor, we are operating from a position of strength and remain confident in our ability to create durable value for patients and shareholders. And with that, I will now turn the call over to the operator for Q&A.

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

On the progress throughout '25. I'd like to use my one question to ask about EMPAVELI launch as we get into '26. You mentioned opening to broaden the accounts there and improve patient identification, diagnosis and all of that. But I noticed that one of the things that you didn't mention when you were listing the indications where there was strong growth potential was IC-MPGN, where obviously you have a differentiated label, but historically, it's been a little bit more challenging to find those patients. Can you talk a little bit about the breakdown of different indications throughout 2026, where you think the low-hanging fruit is, where we can see real growth in the near term and what it will take to break open some of those indication subsets that are a little bit tougher to diagnose and get on treatment?

Thank you so much, Jon, and great hearing you, and thank you, everyone, for joining. So EMPAVELI is on a clear path to blockbuster status. And as you correctly outlined, John, there's not just IC-MPGN, there's also the fact that in the VALO study, we studied EMPAVELI in the pediatric population as well as in a post-transplant setting as well. Now specifically as it relates to IC-MPGN, we believe that the epidemiology in total between the 2 indications is approximately 5,000 patients in the U.S., split more or less 50-50 between those 2 indications. While we're not providing exact breakdowns as to where in the population, things sit at the moment, it is worth noting that in the pediatric population, the IC-MPGN in the post-transplant segment, we see important pickup and differentiation. And that, of course, contributed to achieving more than 5% penetration after the first full quarter in Q4 and contributes to our confidence of reaching up to 50% of those 5,000 patients at peak.

But I guess if you're going to see 50% penetration at peak and IC-MPGN is 50% of the U.S. population, I guess I'm asking, are you going to see equivalent penetration across those different subpopulations, those different subindications by the end of the day? Or are there places that are going to remain more difficult to penetrate?

It's a little early to say that exactly, I think, at this moment in time. It's also important to note that there's quite a bit of overlap between these 2 indications. There's not kind of a hard separation between them in the sense that you can have a patient with a biopsy one day that is more leaning towards C3G and on another biopsy can mean more towards IC-MPGN, which is why it is so important to have covered all phenotypes of the disease -- of these diseases in the clinical trials that we ran. So it's a little bit too early to provide more specifics on that.

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

For SYFOVRE, you've got the 5-year GALE data this Friday that you guys highlighted. What would you have us focus in on within these data?

Thank you so much, Anupam. Well, the important benefits and the continued safety profile that SYFOVRE provides to patients with geographic atrophy, right? So it is by far the largest data set ever generated in geographic atrophy. And what we found through the course of following these patients for a full 5-year period is that patients who are on treatment for 5 years can save as much as 1.5 year of tissue. So as I think you can appreciate, that's an enormous benefit to 70- or 75-year-old individual who obviously, in the twilights of their lives depends so much on their vision. So we're incredibly proud and incredibly happy with the data that we have generated and look forward to presenting it on Friday. I don't know, Caroline, if you would like to add something.

Thank you, Cedric. I think what will be meaningful for retina physicians is that we have this extended trial with 5 years of data that we continue to show increasing effects over time and that retina tissue can be meaningfully saved. And these findings might lead to earlier treatment for patients with geographic atrophy. So we really look forward to presenting this data. Thank you.

Our next question comes from the line of Tazeen Ahmad of Bank of America.

I maybe wanted to follow up on that 50% penetration for EMPAVELI. How long do you think it's going to take to reach that? I know that a big point of discussion among investors is like the ramp of your launch. Is it going to be more steady? Or could it accelerate and become more steep? So any thoughts you can provide on patient finding efforts and what you think realistically the time to onboard patients will take? That would be helpful. And then can you just talk about what the competitive dynamics are so far relative to how doctors are viewing EMPAVELI versus FABHALTA? What are the types of patients that they might still be waiting to see if EMPAVELI might be better than relative to FABHALTA?

Thank you so much, Tazeen. Well, as it relates to the ramp, I think you correctly outlined that we should expect steady ramp and steady growth as is quite typical in rare diseases. And again, I think we have seen that happen in the past couple of months and expect that to continue to be the case. Competitively, as already outlined when Jon asked the question, there is kind of the clear differentiation that we have and kind of the unique positioning without competition right now in the pediatric segment as well as in IC-MPGN -- that is, of course, a huge advantage. Also in the pediatric population, I think the disease tends to progress more quickly. And what you see in the field based on what we have seen since the launch is that the appreciation for the efficacy and safety profile of the drug really stands out. Also in the post-transplant segment, of course, that is a very important place. Most -- majority of patients with these diseases will have a relapse because this is a genetic condition at the end of the day.

Our next question comes from the line of Timur Ivannikov of Cantor.

This is Timur on for Steve Seedhouse. For EMPAVELI launch, I think you mentioned strong momentum in C3G in 2026 with quarter-to-quarter variability. Could you talk about some of the variability factors? And do you expect to provide start forms again at some point or any other form of guidance?

Thank you so much, Timur. I will hand that question over to David Acheson.

Hope you're doing well. Thank you for the question. So on the variability, it's just -- it's ultra-rare disease. I think it's important to note that you'll see an influx of potential patients coming in on start forms. That does vary week over week, month over month. So I think it's just something that we need to pay attention to. But I feel very good about the momentum that we came into 2026 with -- from the launch last year on the strength of the product and the patients that we're getting on the brand, which is very positive. And can you repeat the second part of your question for me?

Yes. I was just wondering about the start forms or any other type of guidance for the product?

Yes. So moving forward, we continue to report on revenues for sure and start forms, but we're not going to give any additional guidance on start forms that we had in the third to fourth quarter.

Our next question comes from the line of Yigal Nochomovitz of Citigroup.

Could you talk a bit about the prefilled syringe? I just want to get a sense of how much it matters for the retina docs in terms of the practice flow and efficiency. And when you say renewed growth in 2027 for SYFOVRE is the driver behind the statement, the launch of the PFS. And then more specifically on the practice dynamics, since the space is very limited for the physicians, for the fridges to store the drug, is there an advantage to the PFS in terms of practice dynamics in storing the drug with that presentation?

Thank you, Yigal. Those are excellent questions, and the PFS will make a huge difference for us. And we have, of course, our Chief Medical Officer with us here, Caroline, to speak a little bit more towards that.

Thank you. So the prefilled syringe is really a practice-enabling innovation, and this is going to offer convenience and efficiency to retina physicians. And from my experience as a clinician and also from being heavily involved in development of our prefilled syringe, this is going to support the ease of clinical use in patients with geographic atrophy. So we really think that this is going to be transformative for physicians and their patients. When it comes to specifics about the design, I think that retina physicians put their input heavily into how we design this, including the box, the complete package, and we'll be very, very pleased with how it fits into the refrigerators. We also have some other things that will be helping be transformative for SYFOVRE with renewed growth, and that's functional OCT, which was mentioned in the call.

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

I was wondering if you could provide any further color on the recent improvement in co-pay dynamics for SYFOVRE and how you think about the quarter-over-quarter cadence of sample use and kind of the sales trajectory as you input this into your trajectory?

Thank you so much, Salveen. Tim, can you elaborate?

Sure. So as you probably saw, Salveen, the Patient Assistance Organization is open for reimbursement for co-pay assistance with geographic atrophy patients. At this time, we don't really have any sense of what that means in terms of dynamics from a free goods perspective. As you'll recall, last year, we had 12% to 14% fluctuating on a quarterly basis. But really, what this represents is an important advance for the patients who have been unable to pay for their treatment in geographic atrophy.

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

Congrats on all the progress. I realize for the nephrology Phase III studies are just recently coming up and running now, but any color you can provide on the expectations for enrollment there? Do any of these centers have preexisting experience with EMPAVELI? Just how that enrollment might pan out.

Thank you so much, Colleen, for that question. So we're very excited about these 2 Phase III clinical trials in FSGS and DGF, where we think EMPAVELI's potential can make a huge difference as it did in C3G and IC-MPGN. It's a little bit early to give projections on what the enrollment will look like, but the excitement around kind of continuing the trajectory in the kidney is very strong. What really stood out from the VALIANT study is the exquisite target engagements and the control of the complement pathways that we see in the glomerulus, which we believe will translate in a similar efficacy profiles in these conditions.

Our next question comes from the line of Phil Nadeau of TD Cowen.

We wanted to focus on SYFOVRE revenue trends for Q1 and 2026. Tim, putting your comments together, it sounds like you expect typical seasonal factors. For Q1 last year, sales were down $37 million quarter-over-quarter in Q1 '25 versus Q4 '24, although there was a big impact of free product in that downtick. So how will the seasonal factors in Q1 of '26 compare to Q1 of '25? And then more generally for 2026, it sounds like you guys are suggesting relatively stable revenue for SYFOVRE. So I want to make sure I understand that we should be modeling something, full year 2026 similar to full year 2025?

Sure. So yes, I think the one thing to remember, there are a couple of seasonal dynamics in the first quarter, one of which we tried to manage a little bit. So as you'll recall, last year, we had a fourth quarter spike in revenue that was as a result of some inventory build across the channel. So that included at the physician offices as well as the distributor. We really did our best to manage that this year. So we think there may be a bit of a modest swing in the first quarter, but much more muted than last year. We also typically have some seasonal dynamics like weather and reverifications in the first quarter. So bearing that in mind, we think across the year, that's the main seasonal quarter for us. There is a little bit at the end in the fourth quarter. But as you rightly point out, we expect sort of a modest cadence to growth over the course of the year.

Our next question comes from the line of Annabel Samimy of Stifel.

This is Jayed on for Annabel. I just want to revisit the SYFOVRE doses delivered. It was flat quarter-over-quarter, I think you mentioned due to some seasonality. But there was an improved split favoring commercial doses. Agnostic of the pay -- the co-pay assistance funds coming back, do you expect that split to be more favorable towards commercial doses going forward in 2026?

Sure. So thanks for the question. So what we really felt happened in the fourth quarter was a touch of seasonality. When you look at the amount of doses we had, it was 89,000, and sort of there are roughly 90 days in a quarter. We had a couple of a longer holiday stretch that may have impacted things. So it was really not a significant change from a commercial doses perspective in the context of that seasonality in our view. But from the free goods perspective, we saw a range of 12% to 14% over the course of 2025. That bounced around. And so this was, I think, pretty much in line with what we expected in the fourth quarter. As you may recall, sometime in the third quarter, the patient co-pay assistance organization was open for existing patients, and that may have led to a small downtick in the total free goods in the fourth quarter, but it's really hard to say.

Our next question comes from the line of Ellie Merle of Barclays.

Two for me. I guess, what are you looking to see in the Phase II data, SYFOVRE in combo with APL-3007 next year? And how you're thinking about what would be meaningful there? And then just a clarification on the C3G IC-MPGN comments. The 50% penetration that you mentioned, I'm sorry if I missed this. But I guess, is this the base case that you'll treat 50%? Or are you saying that half the population will become challenging to treat? Just trying to understand that 50% comment.

Thank you, Ellie. Great hearing you. So the GALLOP study is a study we're really excited about. What we do there is a subcutaneous injection with an siRNA product against C3. And that lowers the systemic levels of C3 by approximately 90%. What that does is it translates to actually a lowering of the C3 levels in the eye as well. And it gives a stchiometric advantage to SYFOVRE to do its job. We believe that this study, if successful, will allow us to treat every 3 months instead of every 2 months, and to increase the efficacy, which is already important, of course, from SYFOVRE to numbers well above that. What well above that means, we will define at a later time point. But I think, again, kind of really, really exciting study for us, where I think we can again change the paradigm in geographic atrophy as we have done before. As it relates to the C3G and IC-MPGN population, so we said we believe that up to 50% of the epidemiology would be patients that could end up being treated with EMPAVELI. What I think is important in that context is, again, that we -- I think we're very good at having a conservative estimate of the epidemiology for C3G and IC-MPGN. It is noteworthy that our only competitor in this space has an epi that is meaningfully higher. And the fact that we have more than 5% penetration in the fourth quarter, which means that we had a very, very strong launch, among the strongest launches in rare diseases. And maybe a conservative epi on our side or a combination of both. So again, we feel very good with where EMPAVELI is headed with what we did in Q4 and the trend that we continue to see as this launch progresses.

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

I guess for EMPAVELI, you've previously talked about there being an initial bolus of patients and then it sort of settles down into more of a steady state, monthly or quarterly growth in new patients. I'm wondering, sort of where are you at that? Are you through that bolus and into the steady state now? Or are you still working through some of that initial bolus of patients that you're expecting? And maybe you reach steady state later this year?

Yes. Thank you, Lachlan. I will hand that over to David Acheson to answer.

Thanks for the question. So yes, like we talked about last year in the Q3 launch through Q4, that bolus of patients typically hits early in the launch and get on product shortly after the launch. And we saw that happen in the fourth quarter. So -- which was great to see. Now we're at that steady state place that we talked about in prepared remarks and what Cedric mentioned in the opening portion of some of the questions here. So I would be confident in the continued steadiness of what we're going to see moving forward.

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

Maybe just one on the commentary around the ability to fund yourselves through to profitability. Just curious how pipeline could impact the timing and trajectory of that, specifically maybe 9099 and 3007, what are the pushes and pulls there that could move that profitability closer or further out?

Yes. Thank you, Judah. That's a great question. At least for the moment, we've incorporated all of that into our thinking when we talk about the fact that we may have a small increase in total operating expenses this year, as you'll see in 2024 and 2025, it was pretty flat overall. We have a -- may have a solid increase over the course of this year with the -- our FSGS study and our DGF study really ramping up and then some of these new programs that you mentioned like the Beam program coming online towards the end of the year in terms of potential larger cost structure. But ultimately, we've been pretty good about managing our operating expenses, and it really comes down to the revenue growth that will make that happen. We look at the world at least today from an operating expense and net revenue perspective. And if you look, taking -- adding back stock-based compensation, we've been pretty close to an operating adjusted EBITDA neutral level over the last year, and we expect that to come more into focus over the course of this year.

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

Just on SYFOVRE, David, just a couple of questions. I think you indicated there was sort of an initiative to help patients sort of end up on the right plan which sort of improves their coverage of SYFOVRE. I'm just curious sort of as you come into the new year, if you've sort of seen meaningful progress on that. And then also, I'm just curious in terms of the free goods, are you seeing those patients sort of typically sort of get dosed with free goods and then they see that they can't get covered or can't get patient assistance and drop off? Or are you seeing sort of a persistence of it? I'm just sort of trying to understand that in terms of understanding sort of how patients are coming in and sort of identification for the market.

Thank you, Doug. David will answer the question on SYFOVRE, and I will -- the first question, and I will then talk a little bit about the free goods.

Doug, thanks for the question. So on the reverification piece and just kind of patients coming over on insurance plans and what we did last year. So we put a lot of effort in last year with our field reimbursement team to make sure that we can help offices get educated on which plans would be specific to patients that have a gap, right, where they couldn't get covered for a geographic atrophy treatment or specifically, SYFOVRE. So we did a lot of work on that. Our Apellis Assist, which is our hub, has also been integral and playing a part of making sure education to both the patients and the offices during the reverification period of their insurance, which happened in the fourth quarter coming into this year, helps them understand where they've got opportunities for benefit -- for treatment for benefit and payment. And all of that happened coming into this year. And I can tell you, the reverification process is winding down. It's been relatively smooth. I cannot tell you how many patients actually changed plans or moved over. But we did what we could to continue to educate so people had access to additional information. And I'll hand it back over to Cedric.

Thank you, David. Well, as it relates to the free goods, I kind of want to highlight something that is really important, and that is that in 2025, we made a deep commitment as a company to support the retina practices to deal with, at the end of the day, a lot of patients being in a position where they could not afford the co-pay on their products and to make sure that these patients would not go without treatment, right? So that is our medical commitment to patients, and that is what we did throughout the year last year, but we will always continue to do when it is needed. So that is really important and will continue to be important for us. I think within the context of next year as well, I think it is hard to overstate how impactful the disruption was on the workflow in the retina practices when this occurs, right? So that is something that needs -- had to find a new place of settlement that was important. And during that period, there was inevitably kind of, I would say, a lowering of how many new patients would come on treatment with geographic atrophy because within these retina practices, that is easy to essentially punt, right? So that dynamic is also something that you should expect to see change over time. I think what is really important and gratifying to see right now is that within the retina world, we're starting to find a new cadence and a new place of stability after what was a very difficult year for these physicians and patients.

Great. And it's great to hear about the commitment to providing drug to patients.

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

You made some comments on kind of the patient pipeline for EMPAVELI in C3G and IC-MPGN. And I guess, what level of visibility do you have there? Is it as granular as understanding where the patients are at certain sites, outreach of those patients? And then just a second question on PFS. Just kind of curious, is it more of expand the market? Or is it also share gains against the other competitor?

Thank you so much, Derek. Well, first of all, as it relates to the pipeline, I think that is one of the most -- one of the more gratifying aspects of the launch that we have seen. First of all, of course, there was the epidemiology, which, as you all know, was difficult to estimate and feeling that we really kind of hit the bullseye in terms of estimating that and arguably conservatively estimating that. Then, of course, the very good -- one of the best rare disease launches that we are having in the kidney here with that penetration within the first full quarter. But then, as you mentioned, also the pipeline. So if you take the number of patients that we actually identified, which then flow into start forms and from start forms into being on treatment, that upstream pipeline today is larger than it was before the launch. In spite of course, many of these patients now having transitions to start forms and being on full treatment. So that tells us that, again, we got the epi rate. We continue to identify these patients and why we expect this launch to be one of steady growth. And then as it relates to your second question with the prefilled syringe, I think it will be a very important driver of share. We have plenty of examples from the wet AMD space with anti-VEGF products, where it has been proven over and again that having a prefilled syringe on the market makes a very important competitive advantage for a product. That is one that we are working towards. Of course, we expect our competitor at some point to come out with a prefilled syringe as well. But right now, we have a head start that we're very happy with and that will allow us to position ourselves well. As it relates to share, it will also make a difference. The fact that you fit better into the workflow of the retina practice makes it much easier for physicians to treat these patients. Makes it also much easier, quite frankly, for physicians to just try the products, right? I mean, it is not -- instead of taking something, having to draw it from vial in -- through a filter needle into a syringe, et cetera, you take it out of the fridge and you try it, right? So important differences, and I don't know, Caroline, if you want to elaborate on that, but we're very pleased with where we are.

Yes. This is a real innovation, and this will be highly meaningful to physicians to have this way to treat their patients efficiently. So I speak from my personal experience and what I've heard from colleagues that I think that this will help to expand the market for geographic atrophy.

Thank you, Caroline. And worth noting is that the prefilled syringe that we have from a CMC perspective, from a quality, from -- is absolutely has been spectacular for us and outpaced our own high internal expectations. We're really happy not just with the pace at which we're bringing into the market, but also with the quality of the prefilled syringe.

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

This is Anthony on for Ryan. So we wanted to ask, can you walk us through how retina specialists can potentially use OCT-F in their practices, how this could increase the size of the GA market? And then if you have like an approximate time line for when you anticipate having appreciable amounts of real-world OCT-F data for analysis? And if possible, I have a follow-up.

Thank you so much, Anthony. Well, we're touching on Caroline's favorite subject here. So for those on the call not familiar with OCT-F, OCT-F is functional OCT, and it is a technology that we developed in collaboration with University of Bonn in Germany, where we used our -- what is the largest data set of microperimetry data ever generated in the retina, where we use that technology to essentially take an OCT and translate an OCT image into what a real functional mapping of the retinas. In other words, what is the retinal sensitivity in the patient across the retina. And what really stands out when you analyze patients with geographic atrophy over time is the impressive loss of retinal sensitivity that these patients experience. And from a timing perspective, what you should expect to see this year -- and it started at Angiogenesis 2 weeks ago -- is that we will redefine for retina specialists and for family members of patients, what it means to have this disease. And why is this so important? Because right now, a lot of people believe that geographic atrophy happens on the border of a lesion. And that is not the case. It is really a pan-retinal neurodegenerative condition, and we can now image that. And commensurate with that, of course, we can image and quantifiably visualize what the benefit is of being on treatment with SYFOVRE. In the first step this year, we will be focused on, again, as I mentioned, raising the awareness around how impactful geographic atrophy is on patients. And then it becomes our mission to make this available in the retina practice so that a physician in a one-on-one interaction with the patient can actually do that analysis, assess the patient and again, track what the benefit is of being on treatment with SYFOVRE to that patient. Caroline is in love with this technology, speaks about it at every retina conference. And maybe you want to add a couple of words?

Physicians are really excited for this technology finally to have a way to link structure to function. This was shown at our recent presentation at Angiogenesis, and I had multiple people reaching out to me after. But what I would say is that this will help with earlier diagnosis of GA. It will help position -- support the patient's journey. It will help physicians better understand this disease. And we expect this to support adoption of SYFOVRE, which is the currently approved agent with every other month dosing, support their use in patients and help keep patients on their treatment schedule with up to every other month by showing them and showing their family members how they're doing, we also hope that it helps highlight other diseases, including wet AMD and other things that we're evaluating as a research tool.

Our next question comes from the line of Douglas MacPherson of Mizuho.

I'm interested in the sort of competitive dynamics of the market. Firstly, are you seeing the complement inhibitor class to treat GA, seeing that hold steady or perhaps growing modestly? And then I think you're holding pretty solid at 60% market share. As far as new patient starts, what proportion are you seeing versus competitor? And have you seen any impact of the 5-year GALE update in November? You see any impact on that on new patient starts or on compliance?

Thank you, Doug. Good hearing from you. So as a class, we believe that -- it's hard to believe that it's still the early days of what can be done for patients with geographic atrophy. And of course, with the differentiation of our product and the enormous amount of data that we've generated, including over, as you mentioned, the full 5-year period, we are really well positioned to continue to shine competitively. I will hand it over to David Acheson to talk a little bit more about market share.

Yes. Thanks for the question. So you're correct. We're holding steady at 60% market share, which we're confident in. And we feel really good about where we're coming into 2026. I can tell you that we're really confident in the competitive strength that we have, including the GALE data that we just talked about and came out this week. I think it's important for us to note that nobody else has that data, and it's a big strength for us to have that kind of data with the patients that are in the long-term study. And our focus, quite frankly, is really being disciplined on execution and to continue to innovate with what we're doing with the brand and continue that leadership reinforcement moving forward within the space. So the market share is part of that, but certainly, driving innovation is a part that we'll continue to drive uptake, market growth and our share growth as well.

Thank you. I would now like to turn the conference back to Cedric Francois for closing remarks. Sir?

Thank you very much, and thank you all for your thoughtful questions. We look forward to updating you on our progress, and I believe that we're speaking with many of you later today as well. Thank you so much, and I hope you have a great rest of the day.

This concludes today's conference call. Thank you for participating. You may now disconnect.
