Thank you, Clay. Hello, everyone. With me today are Rob Torbay, our head of commercial, David Berman, our head of R&D, and Brian DiDonato, our chief financial officer. We will be happy to take your questions at the end. At Immunocore, we are driven by a clear mission to bring transformative immunomodulating medicines to patients. In 2023, we continue to advance our three strategic pillars of maximizing the potential of ChemTrack, advancing our clinical portfolio, and continuing to innovate for sustainable growth. Let's look at the first one. On ChemTrack, last year, we achieved 239 million in net ChemTrack sales. Going into 2024, we see three growth opportunities. First, continuous commercial growth driven by the US. Second, mid-term growth driven by Q4 data from TEBI-AM trial. And third, long-term growth with the ATOM trial expected to start recruiting this year. The second pillar on the portfolio. We continue to advance our clinical portfolio With the announcement of our first PRAME phase three trial in first line advanced cutaneous melanoma, we intend to randomize the first patient in Q1. PRAME clinical data updates in melanoma, ovarian, and lungs will come throughout 2024. Reflecting our enthusiasm for the PRAME targets, we are advancing two new candidates into the clinic this year. In December, we submitted the CTA for a first-year class candidate targeting P. will in colorectal and GI cancers. And we continue to pursue a potential functional cure in HIV with phase one beta for the first half or second half of 2024. The third pillar is an innovation. In last month, we announced that we had added two novel tissue-targeted autoimmune programs one for type 1 diabetes and the second for dermatology indications. You will hear more about each of these exciting programs from David. These additions expand the therapeutic areas we aim to treat to three. And now I'm happy to hand over to Ralf to share more information about KimTrack. Ralf?

Thank you, Baheja. Hello, everyone. 2023 was a catalyst year for ChemTrack. In less than two years from our first approval, we have transformed medical practice in metastatic uveal myeloma and established this pioneering TCR medicine as the first-line standard of care across all launch markets. We have treated over 2,000 patients globally since the start of our first clinical trial, and I'm very proud of this team's achievements and commitment to patients. KimTrack is currently approved in 38 countries and launched and reimbursed in 12. With the publication of KimTrack's long-term three-year overall survival in the New England Journal of Medicine, we continue to raise the bar of survival, and I look forward to the impact the team will have in 2024 leveraging this data. I will now take you through the figures and financial performance in more detail. For the full year 2023, ChemTrack generated $238.7 million in net revenues, which represents a 70% year-on-year growth. In the fourth quarter, we reported $67.6 million in net revenues, which represents an 8% increase from the prior quarter. This growth was primarily driven by continued commercial progress in the United States. In Europe, we launched in six new countries and reached pricing agreements with Italy and Germany. In France, we have been recognizing revenue since day one and have been accruing for an expected negotiated price. In the international region, we signed pricing agreements with Canada and Australia, which we are launching through the first half of the year. Our goal in 2024 is to continue our growth momentum in the United States and reach more patients globally, including our next country, Spain. We're also excited to potentially expand the benefit of ChemTrack to additional indications with our clinical program, which I will take you through in the next slide. We believe ChemTrack has significant potential for additional growth in the medium and long term, driven by two registrational clinical trials. The TEB-EAM study builds on the ChemTrack Phase I-II cutaneous melanoma data that has shown a 76% survival rate at one year with an acceptable safety profile. Enrollment is going well, and we expect top-line results from the Phase II portion in the fourth quarter of this year. All of the evidence with ChemTrack points to our platform being potentially transformative in the early disease setting. We were honored to work with EORTC to launch the only ongoing registrational adjuvant study in uveal melanoma, the ATOM trial. We anticipate randomization to start in the second half of this year.

Now let's bring it all together in the next slide, please.

Today, we're only at the beginning of the ChemTrack journey, where the benefit is focused on 1,000 patients with metastatic uveal melanoma. With the TEB-EAM trial, we see the potential to help 2,000 to 4,000 additional patients with second-line plus metastatic cutaneous melanoma. With the ATOM trial, we could be unlocking the early-stage uveal melanoma potential and bringing the benefit of ChemTrack to up to 6,000 patients across all three indications. On a personal note, I am excited about our future because of this past year. I had the privilege to meet one of the first patients in our clinical trial, a parent of four, that has been taking ChemTrack for seven years and is doing well. I also met our first patient in our Early Access program who remains well and on treatment, and a physician who expanded their practice to handle the volume of patients who are now surviving. These people remind us every day of why we need to persevere in helping patients and advancing the science.

I'll now hand it over to David to talk more about our program. Thank you, Ralph. I'm happy to share an update on our clinical stage portfolio, and let's start with PRAME. Our PRAME opportunity stands across multiple solid tumors, including melanoma, ovarian, lung, and endometrial carcinoma. By the end of this year, our franchise will include three clinical programs targeting PRAME, including a program for HLA-AO2 with a half-life extension, and a program for patients who are HLA-A24 positive. Today, I will focus on the lead program, F106C. Across the four major tumor types we are studying with F106C, the melanoma data matured first and provided confidence to launch the Phase III PRISM-MEL301. We will share the melanoma monotherapy and the anti-PD-1 combination data in second quarter. After melanoma, The ovarian monotherapy and chemotherapy combinations have been maturing, and we are on track to share this data by third quarter. For lung, we are currently enrolling monotherapy and combinations. Unlike ovarian and melanoma, where we enrolled all comers, for lung we have focused on select subsets where we would expect to see initial signals before expanding more broadly. This data will continue to mature in first half and will be shared by fourth quarter. Additional exploration continues, including endometrial, contract combinations, and dose confirmation. Several data points led to the initiation of the Phase III trial in first-line melanoma, including F106C monotherapy activity in heavily pretreated patients, the ability to combine with anti-PD-1, and insights that our platform works best in early-stage disease. We have opened clinical sites for the Phase III trial and expect to start randomizing patients in the near future. We are pleased to have a clinical trial collaboration and the Volumab supply agreement with BMS for this trial. I will now turn to highlight the power of our target discovery engine with a novel first-in-class target against Pwil1. R117C is the first immunotherapy to target Pwil1. a protein which is expressed in colorectal carcinoma, a tumor that has historically been insensitive to checkpoints. P. will is an attractive target since it is not expressed in normal vital tissues, is a negative prognostic marker, and has broad expression in about a quarter of colorectal cancer patients. The CTA in Europe was submitted in December of last year, and we are on track to start the trial by the second half of this year. Turning now from oncology to HIV. In addition to redirecting T cells to kill cancer cells, we believe that technology can be used to redirect T cells to kill virally infected cells. For HIV, the current standards of care of antiretroviral therapy block replication, but cannot eliminate the virus, which hides it as a reservoir in CD4 T cells. In the single ascending dose portion of the M113V trial, we demonstrated safety and biomarkers indicating target engagement. The goals of the ongoing multiple ascending dose portion are to demonstrate antiviral activity, including one, reducing the reservoir in blood, and two, delaying the viral rebound. As we round up the clinical pipeline, I will transition to highlighting further the versatility of our platform. We validated that our ImTech technology can recruit and activate T-cells against cancer. We are using the same T-cell activation approach to target HIV and chronic HPV. Today, I will share the third platform called ImTi, which has a different goal of turning off inflammation and is intended to treat autoimmune and inflammatory diseases. The current standards of care for ANI are systemic immune suppression, which can lead to systemic toxicity. Our vision for the future is down modulation of the immune system, focused only in the organ or tissue which is under immune attack. As part of our cancer peptide discovery work, we have been mapping the normal human peptidome. Therefore, when we want to develop a program To down modulate the immune attack in a specific organ, we have a large preexisting library of peptides that we know are tissue specific. On slide 20, you can see our MTI molecule. The blue targeting end tethers the MTI to the target tissue. The purple effector end is a PD-1 agonist, which presses on the PD-1 break to turn off the T cell. There is also an FC fusion, which prolongs the half-life and enables less frequent dosing. Our first application is for patients with type 1 diabetes, which remains a large unmet need. Type 1 diabetes results when autoreactive T cells kill pancreatic beta cells, which normally secrete insulin. To protect the pancreatic beta cells, We designed an EMTI that binds to a peptide from the pre-proinsulin protein, which is only expressed in beta cells. The PD-1 agonist effector end will turn off these autoreactive T cells. As seen in the data on the right, we see protection against autoreactive T cell killing only when using an EMTI that tethers to the beta cells. Our second candidate is for skin inflammatory diseases, including atopic dermatitis and psoriasis, among others. We designed an IMTI that binds specifically to a target that is only expressed on antigen-presenting cells in the skin. In a T-cell stimulation assay, we observed inhibition of T-cells only for an IMTI that tethers to the antigen-presenting cell. This candidate has another exciting feature. It is universal and not HLA restricted. This is an example of how our technology can be broadened to all populations. This is certainly an exciting and productive period at Immunocore as we continue to pioneer TCR bispecifics for cancer, for infectious diseases, and now for autoimmune diseases.

I will hand over to Brian. Thank you, David. Good morning, everyone.

Earlier today, we released our financial results for the fourth quarter and year-ended 2023. Please refer to the press release and our latest SEC filing on Form 10-K for our full financial results. This is the first time that we report financials as a U.S. domestic filer, and the comparisons I will discuss are now all in U.S. GAAP. The accounting difference between U.S. GAAP and IFRS is not significant. less than $1 million net in each of the last three years.

I will now share some of the key highlights.

In our second year of launch, 2023 has been an impressive year of Chemtrax sales, with net revenues growing to 67.6 million in Q4 from 62.6 million in Q3, primarily driven by the 13% growth in the United States. Total sales for the year at $238 million were an increase of 70 percent over 2022. As Ralph mentioned, we continue to make best estimate revenue recognition assumptions and associated accruals for France until we achieve final price agreement. In line with the expansion of our portfolio, we have seen R&D and SG&A expenses increase marginally throughout 2023. with a net loss for the year of $55 million, or $1.13 per share. We expect expenses to marginally increase in 2024 as clinical development for late-stage PRAME and ChemTrack programs accelerate. On slide 25, you see our net cash position increase to $443 million in 2023. Additionally, in February, we completed a six-year $402 million convertible bond offering with a 2.5% interest rate and net proceeds of $389 million. We intend to use $50 million of these proceeds to repay our Pharmacon loan in November, which has a rate of 9.75%. Taken together, after this financing, we estimate a pro forma cash position of $782 million. Our ChemTrack sales and current cash put us in an excellent position to transform outcomes for patients by accelerating this portfolio with multiple clinical opportunities across three therapeutic areas. I will now pass back to Behija.

Thank you, Brian, David, and Raul. As you have seen, we have multiple data readouts and study starts planned for the remainder of 2024. It will be a very busy year. Reflecting now on the pipeline, Immunocore has an industry leading by specific TCR pipeline that now spans three therapeutic areas and reflects the large potential of our impacts platform. In the last five years, Immunocore has evolved from a research organization to a revenue generating sustainable company. We look forward with excitement to the next five years when we will maximize the value of ChemTrack expect to launch our frame targeted therapy, and advance our other programs in oncology, infectious disease, and autoimmune disease. Now the full team will be happy to answer questions. Thank you.

Thank you. We will now be conducting a question and answer session. If you would like to ask a question, please press star 1 on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. We ask that you please limit yourself to one question. Our first question comes from the line of Michael Yee with Jefferies. Please proceed with your question.

Hey, guys. Thanks. Good morning and great update. I had a question on the Kintrac advanced melanoma study, which has a readout at the end of the year. And I wanted to understand as part of this phase two, three design, how you think about the primary endpoint and what you would expect the scenarios to be appreciating that I guess you could sort of go to the phase three where there could be trends and you would still go to the phase three. Tell me about the types of different outcomes there at the end of the year, given the Phase 2-3 design. Thank you.

Thank you, Michael. A question, David, do you want to take this one?

Michael, thank you very much. The Phase 2 part of the study has dual primary endpoints of CT, DNA, and overall survival. At the end of the year, the CT, DNA will be mature, and the survival will be directional. And we believe it will be able to inform us on a couple of Key questions, Michael. One is, can we drop one of the arms? Do we really need to include a PD-1 or not? The second question we're going to ask is, can we resize the study? Are our assumptions correct? So I think at the end of the year, we'll have a top line of ctDNA, overall survival trend, and what the next steps are in the phase three.

Thank you. Our next question comes from the line of Jessica Fye with JP Morgan. Please proceed with your question.

Hey, guys. Good morning. Thanks for taking our question. I was hoping you could walk through in a little more detail the various frame updates we can expect throughout the year with details like the number of additional patients we should expect for cutaneous melanoma, how many patients we'll see for ovarian, and, you know, maybe a range of patients for how many we'll see in lung. And when should we expect any update from the endometrial cohort? Thank you.

Great. Thank you, Jess. David, you want to take this one?

Yes. Jess, so we haven't commented on numbers, but I'll walk through the different readouts. For cutaneous melanoma, which matured the fastest, we'll be presenting the data that supported our decision to move to phase three, the data that we shared with the FDA and with KOLs. And we can talk more about that if you'd like. For ovarian, we're still enrolling patients there. That was maturing. That enrollment was a little bit behind melanoma. We're still enrolling ovarian, but that data will be available in the second quarter. With lung, it has been a little bit different. We're enrolling all comers with ovarian and with melanoma. With lung, we have taken a methodical approach to focus initially on subsets where we think we'll see signals before expanding more broadly. For both melanoma and ovarian unlying, in addition to monotherapy, we have combinations. For melanoma, it's PD-1 combinations. For ovarian unlying, it's going to be the chemotherapy combinations.

Thank you. Our next question comes from the line of Tyler Van Buren with TD Cowen. Please proceed with your question.

Hey, guys. Thanks for taking the question, and congrats on another great ChemTrack quarter. Just to follow up on the second quarter PRAME melanoma update, If I'm not mistaken, there was only one cutaneous melanoma patient ongoing as of the update during second quarter 23 earnings. So should we expect more cutaneous monotherapy patients with the second quarter update or not? And regarding the PD-1 combo data, how heavily pretreated are these patients so we can understand what the bar should be that we should compare to?

Thank you, Taylor. Another one for David.

Yeah, so for the first question, yes. At the update last year, we just shared the update of the original asthma patient, so we certainly will have more cutaneous melanoma patients, and it will be sufficient to inform and provide reasons to leave for the Phase III trial. With regard to the second question, I missed which tumor you were posting.

Yeah, for melanoma, with the PD-1 combination data, how heavily pretreated will they be so we can understand what the bar should be?

Yes.

Yes. Tyler, I can address that. So it's a mixture. So there were some patients because PEMBRO is indicated. They could be PEMBRO-naive, but many of them were previously exposed. So it's a mixed population because the primary endpoint is just safety and feasibility.

Okay. That was Mohamed, our CMO.

Thank you. Our next question comes from the line of Eric Schmidt with Cantor Fitzgerald. Please proceed with your question.

Thanks for taking my question, and congrats on the quarter. Maybe one on Kim Track in the phase two slash three relapse refractory melanoma study and the phase two readout toward year end. I think you've commented that if the data are favorable from the phase two portion, they could support a compendia listing. How should we think about a compendia listing with an endpoint that's survival driven as opposed to response rate driven? Thanks.

David, you want to speak?

Eric, very good question. This is something that we'll have to decide on a data-dependent fashion. The survival data will mature in 2025, and we will typically what happens, Eric, is that you submit that, you write a paper or a presentation, you submit that to NCCN. So we will try and submit it, and it's up to NCCN to decide whether or not to accept it. The benefit, of course, is we already have a therapy which has shown a survival benefit, albeit in a different type of melanoma.

Thank you. Our next question comes from the line of Michael Schmidt with Guggenheim. Please proceed with your question.

Thanks for taking our question. This is Paul. I'm for Michael. Mine are also on PRAME, so maybe for David. You know, what is your current thinking on the PRAME registration opportunity in late myocutaneous melanoma? Is this still a focus area given your initiation of the frontline phase three? And if so, how do you think about response benchmarks? Does the recent accelerated approval for MTAG-B impact your view on the setting? And then just a quick follow-up on PRIME and Lung. Can you expand on which particular subsets are in focus and overall strategy here? Thank you.

So maybe David, thank you, Michael, first for the questions. Maybe David to start and then Mohamed.

Michael, sorry, Paul, yes. So in terms of the PRAME, we as a small company have to focus. And so what we have decided is to focus where we believe is both the best opportunity from a technical point of view, but also which is the largest opportunity. And so for PRAME, we're focused on first line. In the late line setting, where the pills were recently approved, that's where we have chem track in an opportunity. And that trial is approving well, and that trial has a survival endpoint. which will lead to a full approval, whereas the recent TILs was an accelerated approval. With regards to the lung question... Yes, do you want to take that?

I'm happy to do that. So with lung, we know it's a very heterogeneous disease, and there's distinct molecular subsets. So based on well-known and well-described subsets, the cohorts that David alluded to that we're exploring are sort of run along those lines.

Thank you. Our next questions come from the line of Greg Savanovesh with Mizuho. Please proceed with your question.

Hi, this is Avantika for Greg. Congrats on the quarter. I just had a question on KimTrack. It appeared that the ex-U.S. sales were a little bit flat, I would say. Is there a reason for this, and how do you intend to keep growing this, and how do you also intend, or how much more growth do you see in the U.S.? Thank you.

Thank you, Avantika. Lal, do you want to take this one?

Avantika, thank you for your question. So look, we've had a very successful set of years, a couple of years in Europe, where we've launched in Germany, France significantly, but as well as Italy and six other countries. So we're really at this phase where we've established ChemTrack as standard of care, and we are well penetrated. So we do see a relatively flat future with some of the launches incrementally adding to the growth there. Now, the primary driver of growth will be the United States, and that will be driven really mainly by us continuing to penetrate into the community and identifying patients earlier.

And as you know, in Europe, it's about country by country for pricing, and so we're continuing that.

Thank you. Our next question comes from the line of Peter Lawson with Barclays. Please proceed with your question.

Great. Thank you. Thanks for taking my questions and congratulations on the quarter. Just as we think about revenues this quarter, kind of what drove the growth in the U.S. business? Any one-timers we should think about and any guidance around how we should be thinking about 1Q now?

Great, Peter. Great question, Ralph.

So, Peter, we had a great 13% quarter-over-quarter growth in the U.S. The main driver for that, if you recall, at the beginning of the year, we said we're going to be focusing on the community and that community penetration. And that's what we did. Now, the majority of our scripts are coming from the community, and that's what's driving, really, the main part of our growth. We're also seeing duration of therapy being sustained with physicians treating beyond progression. So what we expect in 2024 is, you know, the growth to incrementally continue into the U.S. And, you know, beyond 2024 in the midterm, we're expecting the, as David has mentioned, 10 a.m. study data, as well as in the long term, the ATOM trial, which we're very excited about.

Thank you. Our next question comes from the line of Jack Allen with Baird. Please proceed with your question.

hi uh this is charlie on for jack uh i was just wondering if you know for the ovarian uh in the prime franchise would you be able to give us a little more color in terms of the size of the data set uh you're expecting as well as uh duration of follow-up and what you would consider the bar for success there great jack uh thank you david you want to take these questions

Yeah, Charlie, with regard to size, we haven't been commenting on the number of patients, but what we have said is that we will show data that is sufficient in order to inform the level of activity. And the duration of follow-up, we believe, will also be sufficient. In terms of the bar for success, we're looking at answering two questions, which is traditionally what we do in drug development. Is the drug active? And does that clinical activity support registrational trial? So we know the drug is active. And then here in terms of clinical activity, we'll be looking at partial responses, durable tumor reduction, PFS, disease control, and of course, ctDNA reduction, which is emerging as a consistent theme for our platform.

Thank you. Our next question comes from the line of Mukherjee with BTIG. Please proceed with your question.

Hey, thanks for taking our question. This is Jidon for Justin. I was hoping you could just help us think about the efficacy bar for relapse-free survival for the adjuvant setting, and just any thoughts around the neoadjuvant setting as well for uveal melanoma. Thanks.

Great. Jeff, David, do you want to take this one, and maybe you could comment as well?

Yeah, I'll focus on the neoadjuvant first. You know, interestingly, in the original trial, when we looked back, we did have a couple of patients with residual melanoma in the eye. And interestingly, when we looked at those lesions, there was actually reduction in those tumor lesions. So I think neoadjuvant is an exploratory program, and we have a couple ESRs with regard to that. In terms of your first question, which was what is the bar for success in terms of relapse-free survival, What would the control arm be? This is a high-risk population.

Yeah, and I think Mohamed can comment on that.

Yeah, sure. I'm happy to comment.

So really, you know, the way to think about this is that there is no standard in the adjuvant setting. And so the bar, you know, there's no established bar. What we know is that the median time to relapse in this high-risk population, which is the target population, is about three years. And so the bar is that we have to improve above that. So this is the way to conduct a trial in the adjuvant setting, which is a randomized trial that's global that focuses on the high-risk population. Great.

Thank you. Our next question comes from the line of Patrick Trucchio with HC Wainwright. Please proceed with your questions.

Thanks. Good morning, and congrats on all the progress. I have a follow-up on the PRAME Phase 3 program. I'm wondering if you can discuss in more detail the strategy around pursuing first-line treatment, as well as the design that includes that combination with NEVO. How should we think about contribution of PRAME to this regimen and understanding the studies expected to randomize the first patient this quarter? When do you anticipate initial data like ctDNA data to emerge and what read-throughs should we anticipate from that data to potential for the program success on the primary endpoint of PFS?

Patrick, thank you for the question. I think David and Mohamed can answer.

Yeah. So, Patrick, I'll try to answer a couple of your questions. I hope I get them all. But in terms of the phase three frame first-line trial, I think that's what your question was. There were, of course, multiple data points that led to that. the monotherapy activity of F106C, which we'll share, the ability to combine with anti-PD1s, and then knowledge for our platform. And it's true with immunotherapies in general that you always see higher activity as you move from late to first-line. In fact, with CTDNA clearance and contract, we see a tripling of clearance as we go from second-line to first-line. In terms of the design and the contribution of components, the design... is PRAME plus nivolumab versus nivolumab. So that already has built in the contribution of components because we have PRAME on top of nivolumab. Now, there will be a minority of patients in the control arm who do get Opduleg. And so we'll be able to draw a point estimate that most of the patients, in comparison to Opduleg, that most of the patients will have received NEVO monotherapy. So we'll have contribution of components there. And the primary endpoint is progression-free survival. which is globally accepted for approval, for regulatory approval. The secondary endpoint is overall survival. We do have an exploratory endpoint of cpDNA, but that won't be available until the trial is over.

Thank you. Our next question comes from the line of Gil Bloom with Needham. Please proceed with your question.

Good morning, and thanks for squeezing me in. Maybe a quick one on your new P-will acid and CRCC. So, you know, generally, CRCC is an immune desert. Could that be a potential issue for agents of this type? I mean, we've seen a lot of activity for Tevin and the Prem acid and more T-cell infiltrated tumors. Thank you.

Yeah, thank you, Gail, for this question. I'll pass it on to Mohamed, but I just want to remind you that the UV melanoma is a complete cold tumor, as cold as it gets. So that's, I think, where our platform, you want to talk a little bit, Mohamed, about that?

Yeah. This is part of the reason why we're so excited about the P-WELL program and our mechanism, which is very distinct from checkpoints, where we don't need pre-existing immunity or infiltration by the immune system into the tumor. We, you know, what we've shown with Tebby, as Bahisha was alluding to, is that We just need functional T cells in the periphery, and our mechanism drives T cells into a non-inflamed or immune desert. So this is one of the reasons why we're excited about this program and its potential application in CRC.

And then we'll let the data tell us.

Thank you. Our next question comes from the line of Noreen Quibrio with Capital One Securities. Please proceed with your question.

Hi. Good morning. Congrats on the quarter, and thanks for taking my question. So I guess just to follow up on the ChemTrack Phase 2, 3, TebAM study, you know, obviously you're going to be looking at the ctDNA and the trends with the OS. I'm just curious, what kind of reduction in ctDNA do you expect in this setting, you know, sort of to help you inform the decision to drop one arm. You know, how big of a delta are you looking at? And are you going to be comparing, you know, between the two arms, or is it just baseline from the specific arm?

Great. Maureen, thank you very much. David, do you want to take this one?

Yeah, so we'll be looking. So we have three arms, just as a reminder. We have the Ventibus monotherapy, the Ventibus plus Combralizumab, and then, of course, the control arm. And the dual endpoints are ctDNA and survival. In terms of ctDNA, we believe it directionally gives us information, but since it's still exploratory in cutaneous melanoma, we will rely on survival as well. And although the survival will not be fully mature, we have done some simulations showing that we will have sufficient power to see trends in order to drop one of the arms. The size is about 40 patients per arm. And so we think we have enough power in order to make the decision integrating ctDNA and survival.

Thank you. Our next question comes from the line of Jeffrey Hung with Morgan Stanley. Please proceed with your question.

Hi, this is Michael Riad on for Jeff Hung. Thank you for taking our question. Could you talk a little bit more about ctDNA's predictive power on ALS and advanced cutaneous versus uveal melanoma? How far in the treatment course do you need to go to have confidence in its predictive power, and does that power get stronger as you move into earlier lines? Thank you.

Thank you, Michael. David, you want to take it?

Yeah. Michael, so the association with survival, we have validated in uveal melanoma in two independent trials. So when it comes to uveal melanoma ctDNA, we have really strong confidence. With cutaneous melanoma, we have emerging confidence, but we of course don't have randomized trials and we don't have long-term survival. So we will be looking both at ctDNA directionally as an early potential surrogate, and we'll be looking at survival in parallel. We hope that this trial will begin to set up the associations that we have seen in uveal, in cutaneous melanoma, but we acknowledge that we'll need to see both cpDNA and survival and integrate both of those at this early time.

Thank you. Our next question comes from the line of Ahu Demir with Lattenberg. Please proceed with your questions.

Good morning. Thank you so much for taking my questions and congrats on the quarter. Two questions from us. First one is on the pre-melanoma VDOT in the second quarter. In terms of the patient follow-up, could you give us a sense of the majority of patients, how long they were followed up for? And the second question I have is expectation for the HIV med study. What does success look like?

Thank you, Ahu, David, and maybe Mohamed as well.

Yeah, in terms of the PRAME melanoma, I do think we have sufficient follow-up in order to show durability. I don't have the exact follow-up with me right now, but I would say, Ahu, that it's going to be sufficient in order to interpret the data. And that's because, and the reason I say that is because we enrolled a lot of those patients throughout 2023. In terms of HIV, it's a good question because No one has ever been able to show a reduction in the reservoir or a functional cure. So for the reduction of the reservoir, we'll be looking in the blood to see whether we can reduce CD4 T cells with HIV. And in terms of what success looks like that, I think we're going to have to generate the data, share it with the KOLs, and then we'll share that data and we'll be able to interpret what success looks like. In terms of the delay, of the viral rebound, that also is, you know, a very novel, no one has been able to show that. So I think we're going to have to look at the data, discuss with KOLs, and then we'll share the data. I think any sign of delay in rebound that we can attribute biologically to the drug would be a success as an initial step in HIV treatment.

Thank you. Our next question comes from the line of Rajan Sharma with Goldman Sachs. Please proceed with your question.

Hi. Just a quick one on ChemTrack and just kind of thinking about how confident you are in maintaining pricing in a scenario where you do get these additional settings that you've talked to, which obviously potentially significantly increase the number of pages on therapy. I think it's kind of you flagged 6,000 potential patients versus 1,000 currently. So I'd be keen to understand how you see that playing out.

Yeah, Arishan, thank you. You know, I think it would be a good problem to have, but go ahead, Dara.

I agree. Thank you for the question. So look, the way we look at pricing is really the framework that we use is the value that it brings to patients, the value that it brings to society. So, as Bahija said, it's a little bit early for us to comment on that. So, once we see the data, we hope that this is bringing significant value.

Therefore, you know, the price erosion would be minimal.

Thank you. There are no further questions at this time. I would now like to hand the call back over to Bahija Jalaf for any closing remarks.

Thank you very much. So, in closing, I would like to express really my gratitude to our patients, to our shareholders, and to the team. This past year has been a testament to our drive to bring contract to patients, our innovation into bringing more novel targets and entering a new therapeutic area, and as always, our commitment to patients by working with chance of urgency. And as we move forward into the next fiscal year, we'll remain steadfast in our mission to drive growth, create value, and deliver results. I would like to end this call by thanking all of you for your support. Thank you.

Thank you. That does conclude today's teleconference. We appreciate your participation. You may disconnect your lines at this time. Enjoy the rest of your day.
