Good day, and thank you for standing by. Welcome to the Iovance Biotherapeutics Fourth quarter and Full Year 2025 Financial Results and Corporate Updates Conference Call. [Operator Instructions] Please be advised that today's conference is being recorded. I would now like to hand the conference over to your speaker today, Sara Pellegrino, Senior Vice President, Investor Relations and Corporate Communications at Iovance.

Thank you, operator. Good morning, and welcome to the Iovance webcast to discuss our fourth quarter and full year 2025 financial results, business achievements and corporate updates. This morning, we issued a press release that is available on our corporate website at iovance.com. This conference call will include forward-looking statements regarding Iovance's goals, business focus, business plans and transactions, revenue, commercial activities, clinical trials and results, regulatory approvals and interactions, plans and strategies, research and preclinical activities, potential future applications of our technology, manufacturing capabilities, regulatory feedback and guidance, payer interactions, licenses and collaboration cash position and expense guidance and future updates. Forward-looking statements are subject to numerous risks and uncertainties, many of which are beyond our control, including the risks and uncertainties described from time to time in our SEC filings. Our results may differ materially from those projected during today's call. We undertake no obligation to publicly update any forward-looking statements. I will now turn the call over to Dr. Fred Vogt, Interim CEO and President of Iovance.

Thank you, Sara. In 2025, Iovance delivered substantial revenue growth, achieved groundbreaking data milestones and strengthened our financial performance. Our fourth quarter and full year 2025 results underscore our focus on value creation for patients and shareholders. We drove Amtagvi adoption while streamlining costs and optimizing operations. Our operational strength resulted in a robust 30% revenue growth, driven by Amtagvi and our best ever 50% margin from cost of sales in the fourth quarter. For the full year, total revenue of about $264 million was well within our annual guidance range. Our cash runway bolstered by our ongoing cost savings initiatives now extends into the third quarter of 2027. Following our exceptional performance in 2025, we are well positioned in 2026 to surge toward a highly profitable and broad business in solid tumor cancer immunotherapy. We plan to execute across 3 core pillars: First, continue accelerating our U.S. commercial launch of Amtagvi in advanced melanoma; second, harness the power of our TIL pipeline to expand into new indications and next-generation products; and third, hone our operational excellence as our foundation for success. First and foremost, we are gaining positive uptake commercially with a significant potential for Amtagvi and Proleukin to reach $1 billion plus U.S. sales at peak. After a considerable increase in fourth quarter demand for Amtagvi, enrollment volumes in 2026 are accelerating within our broad and continuous expanding network of both academic and community authorized treatment centers, or ATCs. These ATCs are further reinforced by excitement surrounding the real-world experience and benefits of early treatment with Amtagvi. On top of increasing demand, we are benefiting from operational improvements throughout the entire Amtagvi treatment journey, from patient identification through manufacturing to infusion. On the heels of positive momentum in the fourth quarter, we expect remarkable revenue growth in 2026,…

Thanks, Fred, and good morning, everyone. Iovance finished 2025 with positive momentum as we reported approximately 30% revenue growth with 50% margin from cost of sales in the fourth quarter. Fourth quarter product revenue of $87 million demonstrated meaningful growth of approximately 30% from the prior quarter driven by Amtagvi. In our first full year of launch, total product revenue of $264 million increased by 61% over the prior year, driven by Amtagvi revenue growth of 112% year-over-year. That was well within our annual guidance range. We drove this impressive revenue growth in 2025 through ongoing market penetration and earlier treatment with Amtagvi for more patients and an expanding number of treatment centers. The impact of gross to net adjustments remains minimal at less than 2% overall in 2025. Fourth quarter gross margin from cost of sales increased to 50% from 43% in the third quarter. This margin improvement resulted from ongoing operational optimization and disciplined use of capital. The full internalization of manufacturing operations at ICTC also provides uninterrupted supply with agility for further efficiency. Today, we are capable of scale and expansion into new indications globally to bolster revenue without the need for significant capital expenses. Turning to our balance sheet. Our cash position was approximately $303 million at year-end, driven by our commitment to commercial and clinical execution, operational efficiency and financial discipline. We successfully extended our cash position to fund operations into the third quarter of 2027. In closing, our 2025 financial results reflect our commitment to flawless execution and commercial utilization, improved margin and extended cash runway that supports our path to profitability. I will now turn the call to Dan Kirby, our Chief Commercial Officer, to provide additional context.

Thank you, Corleen. Over the course of 2025, we made tremendous progress in 3 key areas towards our ultimate goal to establish Amtagvi as the preferred treatment option for all-eligible patients, who deserve a onetime cell therapy with curative intent. First, our ATC network is continuously expanding. In the fourth quarter, new community centers as well as high-volume academic centers contributed to our highest ever quarterly demand for Amtagvi, which drove our Q4 revenue. Second, penetrating the community market will unlock Amtagvi's tremendous potential as we expedite higher quality referrals to ATCs and begin to treat patients in the community setting. Recently launched campaigns focused on health care professionals and patients are having a positive impact. The community market will expand further and accelerate growth as we build awareness and access. Our third key focus area is to drive treatment and increase penetration earlier when patients benefit most from Amtagvi. Real-world data resonating with medical oncologists has shown unprecedented efficacy with more than 1 in 2 patients responding in the second-line setting, and 1 in 3 patients in later lines of therapy. Initiatives within academic ATCs are also generating positive results from earlier tissue procurement and earlier treatment for specific patient types. For example, ATCs are offering Amtagvi treatment before health status declines in patients with a BRAF mutation, who have no current or pending options beyond targeted therapy. On the heels of our substantial fourth quarter performance, positive trends and an increasing demand have persisted into the first quarter and support our confidence in remarkable growth for 2026. Globally, Amtagvi has the potential to reach more than 30,000 patients annually with previously treated advanced melanoma. We have made significant strides towards expansion, including Amtagvi approval in Canada, pending approvals in the United Kingdom, Australia and Switzerland and additional progress towards resubmitting a marketing authorization application to European Medicines Agency this year. Beyond melanoma, we are preparing for commercial launch in previously treated nonsquamous non-small cell lung cancer, the most common form of lung cancer. This blockbuster opportunity is approximately 7x larger than our current melanoma opportunity, with 50,000 addressable patients for peak sales of $10 billion in the U.S. alone. Our entire Amtagvi ATC network of U.S. academic and community practices can leverage their existing TIL infrastructure for rapid adoption in non-small cell lung cancer upon approval as well as future pipeline indications, such as sarcomas. After recently celebrating my 1-year anniversary at Iovance, I am proud of our accomplishments and inspired by our science and the patient stories that paint a bright future. I will now pass the call to Igor.

Thank you, Dan. In the fourth quarter of 2025, we achieved both our largest manufacturing volume and highest commercial manufacturing success to date. Building upon this progress, all lifileucel manufacturing has transitioned to the ICTC, which is a significant milestone to optimize internal capacity utilization, improve operational excellence, reduce cost of sales and further improve gross margin. I'll also highlight that around year-end, we successfully completed routine annual maintenance at ICTC. During this time, we minimized the impact of manufacturing volume by leveraging our contract manufacturer and increasing internal capacity surrounding the maintenance window. Importantly, ICTC has transformed into a modular facility with capability to provide uninterrupted supply and fully support anticipated global demand today and scale up for the future even during future annual maintenance periods. I will now pass the call to Friedrich.

Thanks, Igor. Today, I'll focus on our 2 registrational programs. First, enrollment is accelerating across a broad and expanding global footprint on our Phase III TILVANCE-301 trial. We are investigating Amtagvi to support a potential U.S. full approval in the current labeled indication and accelerated and full approval in combination with pembrolizumab in frontline advanced melanoma. Shifting to our IOV-LUN-202 registrational trial, lifileucel has demonstrated a best-in-class clinical profile and recently received fast track designation from the USFDA. The objective response rate was 26%, disease control rate was 72% and median duration of response was not yet reached after more than 25 months of follow-up. We plan to present updated data at a medical meeting this year. Key opinion leaders are enthusiastic about these data, which resulted in a meaningful uptick in recent enrollment. We are excited to be on track to complete enrollment this year in support of a supplemental biologics license application. We are also pleased with the progress across the rest of our pipeline, which I am happy to discuss during the Q&A session. I now give the floor to Brian for the sarcoma update.

Thank you, Friedrich. I am excited to share positive initial data from a pilot clinical trial in patients with previously treated advanced, undifferentiated pleomorphic sarcoma or dedifferentiated liposarcoma that have no approved immunotherapy options. Among 6 evaluable patients, the confirmed objective response rate was an unprecedented 50%. Responses were deep and improved over time, consistent with the durability for lifileucel in melanoma and non-small cell lung cancer. These high mortality, aggressive soft tissue sarcomas effect more than 3,000 patients in the United States and more than 5,000 in Europe, including more than 3,500 cases of advanced disease. These patients have poor prognosis and a very high unmet medical need. Grim outcomes with second-line standard of care include response rates below 5% and median overall survival of less than 1 year. In summary, these extraordinary results are what I hoped and believe I would see TIL therapy do in solid tumor cancers when I chose to leave academic medicine to join team Iovance. I'm heartened by this major opportunity for patients and the future of TIL therapy. We look forward to commencing and advancing a single-arm registrational trial as soon as possible. As part of this developmental program, we will also explore other subtypes of high-grade soft tissue sarcoma where patients have no approved effective therapies and urgently await better treatment options. I will now hand the call back to the operator to begin with the question-and-answer session.

[Operator Instructions] Our first question comes from Andrew Tsai with Jefferies.

Thanks for the update. Maybe for the TILVANCE update that you provided, it sounds like enrollment is picking up nicely. So is it possible that we could get first-line melanoma data with Amtagvi PD-1 combo data later this year? But regardless of timing, what kind of ORR and PFS do we want to see compared to PD-1 alone?

Maybe I can take the first part of that, Andrew, and then Friedrich can cover the rest of it. We do have an early interim read in this study, which is the benefit of some of the agreement we have with FDA on this, where we can read ORR as an interim partway through the study. It's in the near term that we'll be able to do that. We can't really commit to doing that in 2026 right now. It's such a large study, but we are very excited to be able to get that data read. And then, of course, if we read that data, it's a blinded study, we don't bind to do the analysis. And if we announce that, we're basically announcing that we're coming to a supplemental BLA at the same time. That's what we'll point out. Friedrich, do you want to talk about the ORR and PFS considerations on that trial, please? Sounds like Friedrich is muted.

I'm sorry about that. I needed to find my window here. Glad to do so. So I think the best idea around the benchmark for this is the pembrolizumab monotherapy data from the KEYNOTE-006 trial. Remember, the trial design of TILVANCE is a comparison of the combination of pembro plus TIL versus pembro monotherapy. The trial is designed with 2 dual primary endpoints with one of them being ORR and the other one being the PFS. So ORR giving us an opportunity for an early read. The benchmark in the KEYNOTE-006 trial for ORR was about in the mid-30s, probably the true real life ORR with the pembro monotherapy is probably more in the 30 and is slightly below percent range. Remember, we have very encouraging data on the efficacy of the combination from our COM-202 cohort IA, which showed response rates up into the 60% range. So that's what's giving us the confidence around a successful readout for the ORR endpoint.

Our next question comes from Tyler Van Buren with TD Cowen.

Can you please elaborate on the big quarter-over-quarter jump in Proleukin revenue and the anticipated split of Amtagvi to Proleukin revenue moving forward? And if the gross margin can continue to improve quarter-over-quarter despite Proleukin likely contributing to a smaller percentage of sales in subsequent quarters?

Tyler, it's Corleen. First, you talked about Q4 split. We did have all 3 distributors ordering in Q4, and we also took [Technical Difficulty] so there's a little bit of buy in there, not crazy. We haven't guided, so I don't have a split for you going forward. What I can tell you on the margins is, yes, we expect further improvement.

And I'll just add on to that, Tyler. We did see all 3 wholesalers, as Corleen mentioned, order in Q4. We've already seen reordering happen in Q1. And moving forward, you should see again regular orders for Proleukin to go with Amtagvi sales. That's our major line of business there. Other two channels will come on this year as they did last year, but it mainly is driven by Amtagvi demand for Proleukin sales.

Our next question comes from Yanan Zhu with Wells Fargo.

This is Kwan, on for Yanan. Can you share with us how the manufacturing success rate change over time? And what is the scrap cost for this quarter?

Can you clarify the last part of that question, what cost?

The scrap cost.

Scrap costs will be in our 10-K filing that will come out around 9:15. But it's consistent with prior quarters. Maybe I'll give some comments on manufacturing success, and Igor can jump in and help as well. I think we don't release actual percentages and stuff here. We don't think that's helpful to investors. It's improving. We're getting better at it. The margins reflect that. You can see the margins are growing. As Corleen mentioned, these margins are being driven, not just really being driven by Amtagvi performance. Proleukin there, it comes in and out. But we've had good margins for 2 quarters in a row now with Proleukin moving up and down. And we expect that to continue and manufacturing success is driving that improvement at the end of the day. Igor, do you want to make any comment specifically about what you said in the earlier part of the call.

Yes, happy to. Thanks for the question, Yanan. So there are really two avenues for improving success rates. One is internal, where we continue implementing improvements in manufacturing and those are a lot that have been implemented and more are coming. And the other avenue is commercial and medical affairs teams working with ATCs and physicians to improve tumor procurement that also results in better product. So both of those have bear fruit so far, and we continue working on both fronts.

Our next question comes from Salim Syed with Mizuho.

Maybe just one on guidance from us. So you didn't provide '26 guidance. Fred, you mentioned that you plan to provide it shortly. Just curious what was the logic not to provide it now? And when we do get it, can you just give us some context like, is it going to be total revenue product? Is it more like a mean or a conservative guidance? Just help us framework how we should be thinking about that?

Yes, right now, we're seeing remarkable growth in the Amtagvi business. We do need to be sure that our projections are well supported. So we're taking some time to do that. It's very early in the year right now, of course. But as I mentioned during the prepared remarks, we're going to be putting guidance out very, very soon. I think you'll see total product guidance. You'll see some guidance potentially on quarters. We'll have to see how our data is supported. One thing I do want to mention is when -- I know you asked about breaking out the products. For the full year of 2025, the revenue from Proleukin, the revenue from Amtagvi have now fallen right in the line with what we were saying a year ago. And that Proleukin generates about 17% of our revenue. If you recall, many, many calls we talked about the 16% number based on the ratio of the price. So we are seeing that long-term balance come into play. And as Dan mentioned, ordering patterns are stabilizing. And we expect normality on that through the year. So you may not see us particularly put a number on Proleukin for one quarter over another, but you can be confident in the long-term ratio of these things and use the numbers you have right now to help support that.

Our next question comes from Reni Benjamin with Citizens.

Congrats on hitting the guidance. Maybe just a couple of questions. One, can you talk a little bit about the fourth quarter kind of acceleration? How much of that came from new community ATCs versus existing academic centers? And as we think about going into 2026, do we hope that the new community ATCs, that number will maybe double, does it triple? Can you give us a sense as to how this is going to grow potentially this year? And then I have a follow-up on the sarcoma data.

Reni, it's Dan. Thank you very much for the question. So for Q4, our base book of business is the academic ATCs, and we saw significant growth in that segment. We did see new community ATCs come on the line -- come online last year. They're coming online as well this year. We expect a learning curve as we saw with the initial academics coming online, so you'll see them slowly increase as the year goes forward. But for Q4, what we saw in the academic ATCs, which is carrying over to what we're seeing in Q1 is that there are certain patient types there that we're not making into Amtagvi treatment, that I mentioned during the script. We have earlier procurement strategies for patients such as BRAF mutated patients, which make up a significant number of those patients inside of the academic ATCs that we were not previously able to access, that our initiatives now are allowing us to access. So we expect growth to continue in the academic segment. And then the community ATCs are coming online now. They're having their process of testing a few patients out and we'll be ramping up as the year goes on. So we'll see more of them starting in the second quarter through the end of the year into '27. Right now, our base book of business is strong and growing with the academics.

Got it. And then just a follow-up regarding the sarcoma data. It's quite new and, as you mentioned, unprecedented. Can you -- it's in 6 evaluable patients, can you give us, a, sense as to when we might see the full data and at what medical conference? And then also, can you share with us maybe any details on the depth and durability of response, right, that you're seeing here for these patients? And I guess if you can just -- if I can squeeze one more in regarding the registrational study. How big do you think this study could be given this rare disease?

Reni, I'll take the first part of that, and then I'll ask Brian and Raj to answer the other part of it. We're excited to present this at a medical congress this year. We haven't identified that congress yet, but obviously, we really like the big ones, like ASCO and ESMO. We'll have to see how the timing goes, but the data is available right now. I do expect we'll be able to put together very quickly for a presentation. So stay tuned for that. It should be pretty exciting. Brian, do you want to take the second part?

Yes. So in terms of depth and durability, I think it's important to note that, obviously, the trial has been running for years. Like all of our trials, our durability tends to be measured in a very long time frame. So I think it will be a while before we'll be able to tell you because of the power of having living therapy on board. In terms of though the depth, what's really exciting to see is these responses, similar to what we saw in lung and melanoma cancers, we can actually see them get stronger over time. Of course, sometimes it happens right away, but we've actually watched really excitingly, these scans get better and better and better. And so we still have patients that, if it was on a swimmers plot, we would see them swimming and on a spider plot, they'd still be dropping. And so we don't even know how good these patients will get. But I think for all of us, it was really remarkable when we saw how many responders we got and how they were deepening. So I think more to come there, but I think it gives us a lot of encouragement.

Marc will provide sample size for the...

Yes. Thank you for the question. So based upon the prior approvals in various soft tissue sarcoma, subtypes recently by FDA, approval size for the various subtypes range between 30 patients and 60 patients, but predominantly in the 40-patient range. And based on the characteristics of this these 2 cell types that we are discussing today, we really expect very similar patient numbers for registration strategy.

Our next question comes from Colleen Kusy with Baird.

This is Nick, on for Colleen. Just for a commentary on the recent enrollment trends for the non-small cell lung cancer study. And could you talk about just latest thoughts on path to full approval in non-small cell lung cancer? And then I have a follow-up question as well.

The fast track designation that we announced today, Nick, was obviously very helpful that provides us with a lot of benefits in working with FDA. As I mentioned in the prepared remarks today, we are planning on the same timing we mentioned before, with this potentially launching in 2027. This is pretty exciting to us. We're finishing the trial right now. And we're very confident that this product provides a great benefit for non-small-cell lung patients.

And then just a quick one on sarcoma. Just wondering if you're considering expanding into other subtypes of sarcoma outside of these initial two?

Yes. And we mentioned that in both the press release and in the prepared remarks, we are looking at additional subtypes. Maybe on one of the private calls, Brian can tell you more about it, but we are looking at additional -- besides UPS and DDLPS, there's a number of other sarcoma subtypes that are of interest and now we see strong activity for TIL in the space, and a lack of approved options, including approved checkpoint options for these patients, nor are there anybody interested apparently getting their checkpoints approved here or they lack the efficacy to do so? We're really going to look across the entire space and really try to tap into this area of unmet medical need.

Our next question comes from David Dai with UBS.

Congrats on the progress. Just first on the Proleukin sales, we see a little uptick in the fourth quarter. I'm just curious how much is coming from restocking and how much is coming from real Amtagvi demand? And then moving forward with Proleukin, is it fair to assume that it will stabilize around that level with the majority of that contributing to real demand from Amtagvi demand? And then I have a follow-up question.

Sure, David. This is Dan. I'll take the question on Proleukin. We saw in Proleukin, as you recall, all throughout last year we had -- when first wholesaler came on in Q2, two were reordering in Q3, all three reordered in Q4. We started to see regular demand come in. We did do a price increase effective February 1. So there was a little bit of buy-in, but not much going into the end of the year with it. The primary driver for Proleukin in Q4 was Amtagvi demand. As we look at Q1, we already have the wholesalers reordering. Two have already placed orders. We're expecting the third to order soon. And then they will continue to move forward with Proleukin orders based on Amtagvi demand. That is our number one source of revenue. You are going to see this level out. And as we look at having Q1 price increases in the future, this will even out as you look at yearly forecast demand.

Got it. And then just a follow-up on Fred's earlier comment around Amtagvi being a $1 billion peak sales opportunity. Maybe just help us understand how you get there, especially, how should we think about contribution of melanoma and nonsquamous non-small cell lung cancer and also soft tissue sarcoma?

I think when I talk about that, David, I'm talking about continued growth in the Amtagvi melanoma in the U.S. franchise, and we're seeing that grow. So we're only in our first year launch here and we're at $264 million in revenue. And again, I know this is all this discussion about Proleukin versus Amtagvi, but Amtagvi is driving the whole thing. Yes, we do sell a small amount of Proleukin for other things, but the vast majority of these numbers are coming from Amtagvi. That's the point we're trying to make. We talk about $1 billion, we think that's the ultimate potential for this product in the U.S. and melanoma. On top of that, you've got non-small cell lung at 7x. On top of that, you've got sarcoma, on top of that you've frontline melanoma. So just bear that all in mind. Do you want to follow up, Dan?

Sure. So $1 billion in melanoma alone is completely achievable. If you look at where we are right now, we're a quarter away through that journey, and we are just loading up the community ATCs right now. If you look at cell therapy launches in the liquid tumor space, they did have the advantage of following an allo transplant treatment modality with hematology and oncology pathway. We're creating a pathway with the solid tumor medical oncologists. So we are standing that up now. And in the initial phase, we're doing over $0.25 billion with both products. And we see that escalating in the U.S. alone to over $1 billion. We talk about layering lung in, and I mentioned in the script, that is a $10 billion opportunity, a much larger market to go into. And sarcoma we do see as being equivalent to melanoma. So we do see tremendous potential to be well over $10 billion to $12 billion in the U.S. with Amtagvi.

Our next question comes from Etzer Darout with Barclays.

Just on gross margins. Wondered if you could comment at all on what may be the near-term impact on the ex U.S. commercial launches, Canada and others could have on gross margins, given the improvement that you've seen to date?

Etzer, I think I just want to make sure I'm understanding. You're asking, what will be the ex U.S. launches, what impact will they have on margins? So all of our manufacturing operations today are in-house. So we're going to have economies of scale. I think that can only help margin, right, as we grow and add in additional volume from those launches.

I can add on to that, Corleen. As we look at it, manufacturing for ex U.S. launches will be out of our Philadelphia facility. So we do not plan on adding additional manufacturing facilities worldwide. We're already servicing those regions in our clinical trials, and we can service them commercially. So there no added expense there. Also, two, if you look at what's going on in the landscape, most favor nation, et cetera, we do not have an ex U.S. price negotiated yet. We're in the process of that as our approvals come. So we do not have a lower price outside the U.S. We are going to see how this situation evolves, but we are in a good position not to have that as we're going through our negotiations with the U.K., Canada, et cetera.

And our final question comes from Asthika Goonewardene with Truist.

So when we start to think about your penetrating into the community in the U.S. and say you have ATCs there. Is there going to be a material difference in the timing it takes to get a community site up and running versus, let's say, what on average it takes you to get an academic center up and running, and how should we think about that? Is there a lot of diversity in the different community settings, maybe ones who already have some sort of a cell therapy program versus those who don't? And then I have two more follow-up questions. I'll ask one of them now. Can you comment on the Tandem data and the better ORR that was seen early this year when that was presented. Can you use this real-world data when your MSLs are talking to physicians?

Great questions. I'll start with the first one regarding the community uptake. One of the things that we do see with the community will be similar to what we saw in the academics and that is just the relationship with the surgeon, the medical oncologist and the cell therapy lab to get up and running for it. That should be a similar learning curve. We did have some academic sites in the clinical trial, so that was the initial wave with the Amtagvi launch. But we are seeing them come online. This is also balanced with the fact that they are closer to where these patients are being treated with frontline melanoma and subsequent therapies, so we can get them to treatment quicker. So the learning curve will go up. As you see with most ATCs, it is a financial reimbursement where they want to run 1 or 2 patients first, make sure the financial reimbursement is there with the payers. We have that established and tremendous coverage with Amtagvi and Proleukin throughout all the payers. So once they see the first two go through, they start to accelerate patients and treatment. So it should be similar to the academics when we look at getting them up and running. You can see the first couple are even on the website right now. In regard to the real-world evidence that was presented at the cell therapy meeting earlier this month, I will say that the MSLs already have that information reactively, and we are submitting that for publication as well to allow it to be more broadly distributed. I don't know if Brian has anything to add on to the real-world data. It is tremendous news about the earlier line treatments. Brian?

Thank you, Dan. Well, first of all, we presented nationally or internationally at the Tandem meeting in Salt Lake City a couple of weeks ago. It got a lot of attention. I've heard personally people very excited but not just because the detail was out, but also it validated what many PIs, KOLs, physicians have been seeing in the clinic. And they need this data and actually help get their message out to their local physicians because the right time to treat the patient is as soon as possible. And you can see what happens, how great the responses are. They're better than we saw in our trial, they're the best in class, and this is the kind of results that we've been looking for.

And then lastly, just on the Proleukin reordering that happened in Q1. Just curious, you mentioned you had a February 1 price increase. Did any of the reordering happen after the February 1 price increase?

So they typically over before the price increase. Wholesalers operate on very low margins. So we did a 9% price increase on both products effective February 1 of this year. So they would do the buy-in for Proleukin in advance of that price increase. We did announce it to allow for payer case rates to adjust, which have happened because we're post price increase right now. So they were aware of the price increase pending and would buy accordingly.

Thank you. This concludes the question-and-answer session. I would now like to turn it back to Fred Vogt for closing remarks.

Thank you again for joining the Iovance Biotherapeutics Fourth Quarter and Full Year 2025 Conference Call. We plan to provide more detail on the U.S. launch growth when we introduce our full year revenue guidance in the near future. Please stay tuned to updates to 2026 on our commercial launch and pipeline as well as our cost optimization initiatives to drive towards profitability. We are motivated by the frequent stories for more and more patients who are benefiting from our TIL cell therapies. As always, we're thankful to our patients, health care professionals and advocacy communities as well as our partners. I would also like to thank our exceptional Iovance team in addition to our dedicated shareholders and covering analyst for their commitment to the mission to remain the global leader in innovating, developing and delivering current and future generations of TIL cell therapies for patients with cancer. Thank you.

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