Verastem, Inc.

Good afternoon and welcome to VeriSTEM Oncology's first quarter 2026 earnings conference call. My name is Daniel and I will be your call operator today. Please note this event is being recorded. All participants will be in a listen-only mode. After today's presentation, there will be an opportunity to ask questions. I will now turn the call over to Julissa Vianna Vice President of Corporate Communications, Investor Relations, and Patient Advocacy for Verisim Oncology.

Please go ahead. Thank you, operator.

Welcome, everyone, and thank you for joining us today to discuss Verisim's first quarter 2026 financial results. and recent business updates. This afternoon, we issued a press release detailing these results, along with the slide presentations that will be referenced during our call today. Both are available on the investor relations section of our website. Before we begin, let me point out that we'll 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. we encourage you to consult the risk factors discussed in our SEC filings for additional detail. Additionally, today we will be discussing certain non-GAAP financial measures. Reconciliations to the most directly comparable GAAP measures are provided in the press release we issued today. Joining me on today's call to deliver prepared remarks and take your questions are Dan Patterson, President and CEO, Dr. Michael Kaufman, President of Development, and Dan Calkins, Chief Financial Officer. I will now turn the call over to Dan.

Thank you, Jalissa. Good afternoon, and thank you for joining our call today. Tomorrow marks one year since the accelerated approval of AVMAP defects in Jocopac, a practice-changing medicine approved for patients with KRAS-mutated recurrent low-grade serous ovarian cancer. Since our launch in May 2025, we've seen steady growth quarter over quarter, achieving $18.7 million in net product revenue in Q1, with nearly 50 million in total net product revenue to date. While we're pleased with the growth we've seen, we believe there's meaningful opportunity to build on the foundation we've established. New patient starts remain consistent month over month, our prescriber base continues to grow, and the reimbursement environment is favorable. As part of our ongoing commitment to optimize our launch, we conducted a focused review of our launch performance and execution and implemented targeted changes to our commercial organization and leadership. I'll walk through these details in a few minutes. I want to underscore that our confidence in the underlying demand and overall opportunity for the COPAC remains unchanged. Moving to R&D, we've made significant progress with our clinical trials for VS7375, our potential best-in-class oral and selective KRAS G12D on-off inhibitor. now branded as the VS7375 Target D clinical trial program. The Target D 101 Phase 1-2 dose escalation and expansion trial is already underway, and we continue to enroll patients and evaluate higher dose levels. In addition, we've also initiated our Phase 2 registration-directed clinical trials in second-line pancreatic cancer, second and third line non-small cell lung cancer, and second line plus metastatic colorectal cancer. Michael will share more about our progress and strategies with these trials. We continue to closely manage our expenses and remain on track for the LJSOC franchise to be self-sustaining in the second half of the year, meaning COPAC revenues will support both commercial operations and any ongoing clinical trials for avudimetinib plus defactivin. As we look to the balance sheet, our focus remains on identifying value-creating, non-dilutive opportunities as we advance our pipeline and deliver for patients and shareholders. With that, let me turn to our commercial update. With almost a year into the launch, we're continually monitoring our progress. As with any launch, There's a natural evolution as we learn more about the market dynamics. We took a comprehensive look at our commercial execution and have taken decisive actions to strengthen it and position the business to the next phase of growth. Most notably, we've appointed a new chief commercial officer, Dan Lyons, who has deep and relevant experience in oncology and rare diseases. He has a strong track record of leading global commercialization strategies across solid tumor cancers, including two successful rare disease and oncology launches at SpringWorks. Dan's leadership will be instrumental as we evolve our launch and bring FMAP defects into COPAC to all patients who could benefit from this important treatment. While Dan will not be joining us on the call today, he's already actively engaged with the team driving new and existing initiatives forward. Turning to the first quarter results, We were impacted by the seasonal headwinds many companies experience, namely insurance turnover and re-verifications, as well as more severe weather, which affected patient access. This impacted both new patient starts and refills. On closer examination, we also observed a specific dynamic where some patients prescribed the therapy by early adopters were much further along in their disease and treatment journey than we would have anticipated. and therefore discontinued the treatment earlier than expected. This is not surprising, as in many cases, these patients likely had no other alternative therapeutic options with proven clinical benefit. Since January, we've seen a rebound with a strong number of new patients through the end of the first quarter. There also continues to be strong physician conviction with a majority of physicians surveyed at our most recent ATU indicating that the COPAQ would be their first choice at their patient's next recurrence. Now onto the numbers. Active prescribers continue to expand, and through April, there have been more than 400 unique prescribers to date. And consistent with previous quarters, we continue to see prescriptions split between GYNONCS and MEDONCS at a 60-40 percentage. Separately, our active patient pool has grown over recent months. indicating patients are staying on therapy longer, but it's too early to provide duration of therapy as it continues to evolve. It's also too early to give an average number of refills, but the trend we are seeing is consistent with what we would expect at this point in the launch. Approximately 65% of commercially eligible patients are using our VeriSTEM Cares copay program. The remaining patients did not require copay assistance, and the average copay for commercially insured patients is less than $30. Time to fill initial prescriptions continues to be in the range of 12 to 14 days due to rapid prior authorization approval, and our payer mix remains consistent with previous quarters at about half commercial and half Medicare. As we look ahead and consider our recent learnings, We focused on three key drivers in our business to help patients realize the full benefit of the COPAC. The first key driver is to maintain the consistent level of demand of new patient starts. This starts with identifying the right patient for treatment. Without an ICD-10 code specific to LGSOC, we've identified other proxy measures within EHRs, including mutational status, AI or MEC use that may indicate an appropriate patient for the COPAC. Our team is actively working with prescribers when these proxy measures are identified in a patient file. Additionally, we've now added incremental personnel to continue to drive demand and support patient adoption. The second key driver is to drive earlier use at first recurrence. Over the course of the launch, we've observed discontinuations that in part reflect use outside of the attended approved patient population and in LGSOC patients who are much sicker than the patient population in RAMP 201 that was the basis for FDA approval. In fact, in some cases, patients were heading into hospice. As multiple physicians have noted, disease progression and complications can make it harder for patients to tolerate and absorb oral therapies Underscoring the importance of using the COPAC early at first or next recurrence when patients have the best opportunity to realize its full benefits. Our recently launched reimagined recurrent LGSOC direct to physician and patient campaign is focused squarely on this shift. The third key driver is to help patients stay on therapy. Recent long-term data from the RANT 201 trial presented at the Society of Gynecologic Oncology showed that after two years of follow-up, patients on the COPAQ achieved durable benefit with discontinuation rates consistent with the package insert. Findings that physicians view as clinically meaningful. A recent exposure response analysis also demonstrated that early side effects can be effectively managed with dose interruptions after which patients resume at the approved dose and schedule. Setting expectations with both patients and physicians around the AE profile and how to manage through it is a key initiative for the remainder of 2026. We continue to see a substantial market opportunity for the COPAC, with growth potential coming from multiple directions. Expanding reach among prescribers who haven't prescribed the COPAC, deepening experience among current prescribers by identifying additional patients in their practices, and shifting entrenched prescriber behaviors to starting COPAC on their first occurrence when appropriate. LGSLC is a relatively slow-growing but unrelenting cancer where patients stay on their first treatment for several years. Therefore, achieving peak share at first occurrence will take time. But we believe the earlier use of the COPAQ drives deeper adoption, produces real-world outcomes that mirror our trial experience, and establishes the COPAQ as the new standard of care at first reoccurrence. We remain focused on our core product launch priorities and sustaining steady growth throughout the year. I'll now turn the call over to Michael.

Thank you, Dan. We continue to make good progress across our pipeline programs, and I'll spend the next several minutes with an overview of our VS7375 oral KRAS G12D inhibitor program. As Dan mentioned, we've named our VS7375 trials Target D. Target D 101 is our ongoing phase 1-2 dose escalation, dose expansion, and combination evaluation trial. In the dose escalation portion, we are now evaluating the 1200 milligram daily dose to fully characterize the dose range available. We will complete enrollment across the various expansion cohorts shortly, as well as the current cohorts evaluating combinations with chemotherapies. And importantly, we are moving to enroll patients into each of our phase two trials, which I'll describe in more detail. As we mentioned last quarter, the FDA requested that we develop separate phase two protocols for any trials where we are seeking marketing authorization. Thus, we have developed three phase two registration-directed trials in pancreatic cancer, or PDAC, non-small cell lung cancer, or NSCLC, and colorectal cancer, or CRC. I'll now provide some detail on each of these. Target D201 is our second line PDAC study. This phase two open label study is designed to evaluate VS7375 at the 900 milligram daily dose, both as monotherapy and in combination with cetuximab. Based on strong preclinical rationale showing EGFR pathway activation in pancreatic cancer and its role as a potential resistance mechanism to RAS inhibition, We are studying the combination of VS7375 and anti-EGFR antibodies to potentially deepen and prolong responses. We're also taking the opportunity to evaluate VS7375 and anti-EGFR antibodies in first-line pancreatic cancer, where we believe we can generate compelling data. It is worth noting that because VS7375 has not been associated with skin rash to date, Combination with EGFR inhibitors is expected to be clinically feasible, and growing tolerability data to date support this. In addition, we are currently studying the combination of VS7375 and gemcitabine nabpaclitaxel, or GNP, in patients with PDAC looking towards a frontline treatment regimen. Target D202 is our advanced non-small cell lung cancer study. This phase two open label study is designed to evaluate VS7375 at the 900 milligram daily dose in patients who have received one or two prior lines of therapy, including a platinum-based chemotherapy and a PD-1 or PD-L1 blocker. We are currently evaluating VS7375 at 600 milligrams daily in non-small cell lung cancer in our 101 trial, and this will provide information at this lower dose. But as in PDAC, we anticipate that the 900 milligram daily dose will be our go-forward monotherapy dose in previously treated non-small cell lung cancer as we look towards potential marketing authorization. We are also evaluating VS7375 monotherapy in patients with non-small cell lung cancer and asymptomatic brain metastases where there remains a significant unmet medical need and an opportunity to improve outcomes. And as previously noted, we are evaluating a combination of VS7375 plus pembrolizumab without or with platinum pemetrexed chemotherapy in the 101 study looking towards a frontline treatment regimen. Lastly, we have our target D203 metastatic colorectal cancer study. This phase two open label study is designed to evaluate VS7375 at the 900 milligram daily dose as both monotherapy and in combination with EGFR inhibitors, including cetuximab or panetumumab in patients with previously treated colorectal cancer. While we do not expect to see meaningful responses for VS7375 as a single agent, this will be critical to showing the contribution of PARTS for potential combination therapy regulatory submission. We're also going to evaluate VS7375 in combination with anti-EGFR antibodies and the modified 12FOX6 regimen in the first-line setting, again, to expand the opportunity and help us improve outcomes in patients with colorectal cancer with the goal to develop a frontline combination regimen. Importantly, across all three Phase II trials, the primary endpoint is overall response rate by blinded independent central radiological review, or BICR, with BICR-determined duration of response, or DOR, as the key secondary endpoint, supporting potential accelerated approvals in each of these three indications. The protocols have been sent to clinical trial sites, and we anticipate the first patient in each of these studies to occur mid-year, if not sooner. We continue to enroll patients and evaluate the 1200 milligram dose, which is the highest practical dose that we can administer to define the upper end of the dosing range. We now have updated PK data that show that the 900 milligram dose delivers serum levels of ES7375 at or above our target level and provides clear separation from the 600 milligram dose. While we are seeing good responses at 600 milligrams, these data, along with good tolerability, support our enthusiasm for advancing the 900 milligram dose in our phase two trials. As additional data emerge, we expect to finalize the go-forward dose across tumor types and combination settings. As we shared last quarter, Our goal is to generate meaningful data sets in these tumor types, both as single agent as well as in combination with other treatments, with the goal of potential accelerated approvals in previously treated cancer, as well as developing combination strategies that position our regimens in the frontline setting across all three tumor types. Now, let me briefly set expectations for our first half update from the Target D101 trial. In terms of patient numbers, the safety data set will include a broad set of patients across target D101. However, the number of patients available for efficacy will still be relatively small. Recall that response evaluations require a minimum of two baseline scans, which are typically six to eight weeks apart, and not all responses occur at the first scan. And of course, duration of response requires follow-up for months after the initial response determination. We note again that meaningful response duration is typically about six months. As we've discussed previously, we believe that administering the highest well-tolerated dose of VS7375 will maximize the chances for each patient to have a meaningful anti-tumor effect. And because the 900 milligram dose has been well-tolerated to date in over 20 patients in the U.S., Our results with this dose will require several additional months over what was originally projected for the 600 milligram dose. At this time, we can also add that the 400 and 600 milligram doses of VS-7375 in combination with subtoxamab are well tolerated, and that we are currently evaluating the 900 milligram dose in this combination. To reiterate, we will only be able to provide a preliminary view on activity overall because we've been able to utilize higher doses in our patients in the United States. That said, we see this first half update as an early checkpoint and believe the data set will be meaningful in terms of demonstrating our progress in enrollment, along with a more mature safety update and more PK data. We do plan to include some patient cases across tumor types and combinations in the update. Later this year, we expect to provide a more comprehensive data set, including tumor-specific breakdowns and more mature efficacy data as we enroll in our Phase II trials for potential marketing applications. Finally, switching gears for a minute to our avudametinib plus defactinib program, we remain on track to report an update on our RAF205 study in first-line PDAC before the end of the second quarter of this year. Now I'll turn the call over to Dan Cockett.

Thank you, Michael. Our full financial results were included in our press release, so I'll focus on the highlights here. For the first quarter of 2026, we recorded $18.7 million in net product revenue and $2.8 million in product cost of sales. Cost of sales increased in the first quarter in line with the percent increase in net product revenue for the quarter. Research and development expenses were $38.2 million for the first quarter of 2026. R&D expenses continue to be driven by both the ongoing Global Confirmatory Phase III Ramp 301 clinical trial with the COPAC and the ongoing VS7375 Target D101 Phase I-II clinical trial in the U.S., as well as higher costs associated with clinical supply and drug production activities related to our expanded VS7375 program. SG&A expenses were $22.3 million for the first quarter of 2026. The expenses were driven by commercial activities and operations, including personnel-related costs, to support the ongoing COPAC launch. I can reiterate that we expect SG&A expenses to remain roughly the same on a quarterly basis throughout 2026, as we remain disciplined in our expense management, making the right investments at the right time to support the ongoing commercial launch efforts. For the first quarter of 2026, non-GAAP adjusted net loss was 42.7 million or 43 cents per share diluted compared to non-GAAP adjusted net loss of 42.9 million or 79 cents per share diluted for the first quarter of 2025. Please see our press release for a full reconciliation of GAAP to non-GAAP measures. Moving to the balance sheet, we ended the first quarter of 2026 with cash, cash equivalents and investments of $181.7 million. We believe our current cash, combined with the future revenues from the MAPC Fax Center COPAC sales, will provide cash runway into the first half of 2027. We remain encouraged by the initial launch and look forward to building on the COPAC's growth in 2026. Given our current trajectory, I'm pleased to reiterate that we believe the LGSOC franchise will be self-sustaining in the second half of the year. with COPAQ revenues funding both the commercial operations and our avutametinib plus defactonib clinical trials. With that, let me turn the call back over to Dan.

Thanks, Dan. Before we open the call to Q&A, our focus for the remainder of 2026 is very clear, and that's to drive strong execution across our commercial launch, move our three phase two trials expeditiously towards potential registrations, determine appropriate DS7375 combinations for frontline strategies, and maintain disciplined capital management while identifying non-dilutive financial opportunities to deliver for patients and our shareholders. Overall, we believe we're well-positioned to deliver on our key milestones this year and continue building a leading oncology franchise in RAS, MATK-driven cancers. With that, we'll open up the call for questions. Operator?

As a reminder, to ask a question, please press star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press star 11 again. Please stand by while we compile the Q&A roster.

Our first question comes from Eric Schmidt with Kantor.

Your line is open.

Thanks for taking my question. Maybe one on each of the two programs. On 7375, what do you think potential partners need to see from either your phase one or early phase two data sets in order to be very interested in the asset? And then two for Dan in terms of the self-sustainability of the COPAC franchise. Can you be a little bit more granular in terms of the revenue that gets you to that sustainability? Thanks.

Sure. Eric, thanks for the question. Just to comment on potential partners, we have had a fair amount of interest and, you know, what typically happens in situations like this, it tends to come down to the competitiveness. I think if there, you know, there's one party interested, it can go on forever. I do think the fact that we've got significant data out of China that aligns well with the preclinical profile, it's really seeing enough data from the U.S. where we show that we can give it in a tolerable way, in a way that can be combined, and then we start to recapitulate efficacy that puts us in the ballpark of still being potentially best in class. Michael, I don't know if there's anything more you want to add there, but why don't you comment, and then we can have Dan C. talk about the expense of second half of the year and kind of what we're talking about being covered.

I think you covered it real well, Dan. We need U.S. data, and we need a lot of detail on the patients and their prior therapy, and we're quite optimistic that we'll be able to deliver on that.

Eric, this is Dan C. So just in terms of the self-sustaining question, obviously we haven't given guidance in terms of the revenue for the remainder of the year, but just in terms of the expenses, if you look at SG&A expenses on a quarterly basis from when we were pre-commercial to where we are now, that increase has typically been around $10 to $15 million per quarter. And then from an R&D perspective, if you look specifically at the A plus F related programs, that spend has typically been about $10 to $15 million per quarter as well. And the majority of that spend is really coming from the RAP 301 trial, which we announced reached full accrual back in December of 2025. So that's now at full accrual. So don't expect that that will increase, more likely be coming down. So that would give you a good sense of what it would take to be self-sustaining within that program.

Very helpful. Thank you.

Thanks, Aaron. Thank you. Our next question comes from the line of Michael Schmidt with Guggenheim. Your line is open.

Hey, guys. Thanks for taking my questions. I had a couple on 73-75, maybe one for Michael first. You talked about the Phase 1 update in the first half of this year, and Maybe if you could just comment a little bit more about how the patients, perhaps, in the U.S. study compared to the GenFleet Phase 1 study that we saw last year, and also you've mentioned different follow-up with, you know, depending on which dose was used, and, you know, so how comparable will the U.S. update be, perhaps, to the GenFleet data from last year?

Michael, you want to take that?

Sure. Yeah, sure, Dan. So, PDAC is generally treated the same way across the world, and frankly, These days, lung cancer, I mean, Keytruda may or may not be the immunotherapy, but it's generally treated with a platinum agent, typically Carbo, and since these are adenocarcinomas, the Pemetrexid, and again, colorectal cancer, it's pretty standard, whether they're getting Folfox or Folfiri, and some people are getting Folfirinox, it's all pretty similar. The patients are fairly similar. I think the most important difference and the reason we want to continue to study our drug is because the tolerability in the U.S. has been substantially better than what was recorded in China. We are not seeing any significant level at all of liver dysfunction. We haven't seen any significant hematologic changes. uh issues at all and we continue to see that even with patients now who are on for many months some who are on for more than six months we're just not seeing that we're also not seeing cumulative toxicities which is really great for a drug victim giving uh chronically We have really not seen anything major with this drug to date, and the numbers are starting to climb. So the 600 milligram dose has been studied for a little bit of a while now, but across a whole bunch of different cancers, it was an open study. We'll have a little bit more specifics on it, but I think the points I made in the call were that it takes a while to get responses here. I mean, you can't even assess the first response until six to eight weeks after initiation of dosing. And remember, when we open a trial, we don't accrue everybody at the beginning. So this is staggered accrual, of course, with staggered dosing. We all wish this could happen immediately. But the first scan is six to eight weeks, and then a confirmatory scan is another six to eight weeks. And then if, like in Tdac, when many of your responses are going to occur in the second scan after the, you know, first scan. because these are tough tumors and they have a lot of scar tissue, it's going to take a while, and that's okay, and that's very good. We absolutely have responses in the first scans after dosing starts, and we've seen responses at second, and we've seen patients who've done really well have shrinkage of tumors and crossed the important 30% threshold for a PR in scan three or four. I don't want to go into any detail, but we're quite pleased with what we're seeing, and we believe that 900 milligrams will be the go-forward dose. So that won't be, the 900 milligram details will not come until the second half of the year, as we said, and we'll be able to give a little bit of data on the 600 milligram, but we would far prefer to give you guys substantial data sets, you know, in the 20 to 30 patient range. with reasonable durability so that we can make some, you and we can make some intelligent decisions on how this drug is stacking up against others. All of that said, we remain very, very excited about the potential for this to be a best-in-class agent. And I would lastly point out that this drug does not carry rash with it at all, nor does it carry stomatitis. And these are really important considerations for patients who could spend a year or more on these drugs.

Okay, understood. And maybe a question on your Phase II program, specifically the 201 study on slide 12, the schematic. And I just wanted to ask, so you have Part A and Part B, and I'm just curious, you know, what the decision process is for you know, either selecting one of the two cohorts, monotherapy or combination, and then whether the part one, you know, A and B patients will be pooled at the respectively selected cohort. You know, will this be 100 patient type, actually it's 80, 80 patient type registration cohort, or, you know, how should we think about the decision path as you have sort of multiple steps in these phase two studies?

Right. Well, beautiful way to put it. And you correctly figured out what we're really doing here, which is to expect that based on what's going on right now at the 900 milligram dose currently in our phase one, we do think 900 milligrams will be good as both a monotherapy and a combination. We think both of these cohorts are going to be important. And we do intend to pull parts A and B. This is sort of a two-step. It's almost a sort of a Bayesian two-step trial, but we're just putting it in here this way so that we can review this in case there's some unexpected findings here, which frankly, would be different from what we're finding already in the one-on-one study. We don't believe that's going to happen, but this was, you know, we discussed it with our statisticians, and we thought this was the most appropriate way to do this. It doesn't really affect our timelines at all because we think both cohorts are going to go through, and we'll have both a monotherapy and a combination. I'll just add one more thing, and that is that these are important cohorts, assuming the cetuximab can add efficacy, but it also, remember, cetuximab brings about an 80% burden of, it's a different kind of a rash than you see with some of the pan-RAS inhibitors. The cetuximab rash is so-called acneiform, and it's actually really well controlled with, frankly, standard acne medicines plus steroids. So a lot of the patients will go on prophylactic minocycline or doxycycline, and that can really mitigate these rations. But it still comes with a ration, and there are patients, even with pancreatic cancer, who don't want that. So we think both of these options will be important, and we think we can deliver very significant response rates, which will be correlated with durability with this kind of a drug because it doesn't have cumulative toxicities for both of these cohorts, and we'll have two different options for patients.

Okay. And then, you know, situximab is clearly an interesting choice, I think, in PDAC, but any plans to potentially evaluate a combination of 73-75 with an investigational pan-RAS inhibitor?

We're absolutely considering that, and we're in discussions with folks. We have generated and continue to generate some interesting data in that regard, so we're absolutely looking into that. That said, frankly, there's a lot of different pathways that deserve study now that we seem to have made a dent in pancreatic cancer, and we're considering multiple other options as well.

Thank you. Thank you. Our next question comes from Faisal Khurshid with Jefferies.

Your line is open.

Hey, guys. Thanks for the question. I wanted to ask about the GenFleet partnership. So when you guys did the partnership, I think you had three RAS programs that you were eligible to in-license. And if you look at the GenFleet pipeline, they have the G12D, the G12C, and a multi-RAS. Can you confirm if you guys are... able to license the multi-RAS and what the considerations around that could be?

Yeah, this is Dan. So those three molecules were not part, well, except for the G12D, which we developed together with them and chose the lead. The other two programs were not officially part of the original collaboration. We continue to have discussions. You know, for us to jump into the pan-RAS space right now, we'd have to be convinced that it was a differentiated molecule and that, frankly, that combining G12D and PANRAS is actually the preferred path we might want to go down. And we think we have so many other options. You know, we're still considering it, but there are a lot of other options to look at for a combination.

Got it. But you do have two more molecules that you can get from Genfleet under the current deal?

We do, and we've not disclosed those targets yet.

Understood. Thank you. Thank you.

Our next question comes from Leonid Timoshev with RBC. Your line is open.

Hey, guys. Thanks for taking my question. I wanted to pivot maybe to the commercial side of A plus F. Really appreciated the color on sort of how you see the commercial strategy evolving, but I guess I'm curious if you could provide more details on how you'll actually affect those changes? I mean, is there a different way the sales force is going to message? Are the promotional materials going to be different? Are the regions going to shift? I guess, how do you actually drive towards those goals that you laid out? Thanks.

No, that's a great question, and the short answer is I'll accept the last one. So we did add two additional sales positions, and that was really driven by the fact that two of the regions were just too big. And so, you know, we said all along we were going to right-size the launch. We were in the process of doing a deep dive. You know, we were about six months in. When we got to the end of the year, we had that seasonal issue, which, you know, frankly impacted refills more than initial scripts. And it was reauthorizations and things like that that would push things from January into February. We actually had some patients we had to put on free drug for a month until things got sorted out. And so, you know, when we talk about the focus for 2026, some of it was just additional training. Some of it is making sure that we're putting the right amount of effort into the visits after the first prescription and not putting all our effort into getting a prescription. And then implemented a number of different steps with information flow between the specialty pharmacy and really our integrated force, which is both the sales team and the Med Affairs team, to make sure that when there's a delay, and we increase the number of calls to patients so that we are in touch with what's going on with the patient, but also a very deliberate link where if there's a dose delay, somebody is calling on the practice, whether it's Med Affairs or the sales rep, to both find out what's going on and then reinforce the messaging that came out of the SGO meeting recently. We had two big events at the SGO meeting, which that and IGCS tend to be our two big meetings of the year. We had the long-term update to Ramp 201, which showed durability and no increase in side effects with cumulative use over a long period of time. But also, we had a poster on the importance of dose intensity. One of the things that you're able to do in a clinical trial when you're interacting in a very regular basis is make sure you're reinforcing the protocol rules, which is if there's a side effect, you delay the dose and you restart at full dose. That works really well with this drug. I think we're finding with med-oncs in particular who are used to the dynamics for chemotherapy are a little different where you may get a response earlier and side effects are cumulative. Where with this treatment, you tend to get early side effects, and, you know, they tend to be predictable things and things if a patient knows they're coming can be dealt with, and then the response becomes later. And so really reinforcing the messaging and really the sharing of data on how important it is to get the patient through that first three months or so so they get the benefit of the treatment. And then we talked about the new campaign that we rolled out. That's something that had been in the works for a little over six months. When you launch with accelerated approval, you're limited in what you can talk about in the early days. And so this was really our next wave of the promotional campaign that had been planned from the beginning and really reinforces the importance of getting on this treatment early I think there's another dynamic going on is also at SGO, there was an early report of a frontline LGSOC study that compared platinum-containing chemotherapy followed by, as part of the same regimen, an AI versus an AI only. And the combination won out. And I think you're going to start seeing patients as standard of care based on the data that just came out that will get the platinum-based chemotherapy followed by AI as frontline therapy, and I think that really sets us up very nicely to be the next therapy that patients get after that.

Thank you.

Our next question comes from Greg Suvanovich with Mizuho. Your line is open.

Hi, this is Sam. I'm for Greg. Thanks for taking our question and congrats on the quarter. Maybe one on 7375. So how should we be thinking about the cadence in terms of the timing of readouts? Is there a specific program or indication that you see has, I guess, the most likely path for a successful registration enabled in readout and data?

Sam, thanks for the question. I'll start and then I'll turn it over to Julissa to give more specifics on what we'll have when. We believe all three of those indications are important for patients and places where our drug, we believe, will work quite well based on preclinical data. So, they're all moving forward in parallel. Our goal is to have those phase two studies largely accrued by the end of this year and then move forward as quickly as possible. Obviously, there's a lot of movement in PDAC we're going to have to monitor. you know, we are in an enviable position as a company of our size that we have multiple programs in PDAC, and we're going to have to see how both of those develop to make some decisions on how best to prioritize things while staying right on top of what's going on in the competitive space, because obviously there's a lot going on in PDAC. And then for CRC and lung cancer, Again, the preclinical data is really exciting. You know, if you look at the GenFleet data in second-line lung cancer, you know, 59% response rate, you know, we're seeing, you know, unprecedented response rates as a single agent. We're starting to see that we can combine nicely with other agents. And so we've got a lot of choices to make around the frontline path in a very short period of time. But while we do that, and we will be doing frontline phase three studies, we will continue to push forward very aggressively on those potential accelerated approval paths.

And I'll just add, Ms. Jalissa, yeah, I think just to reiterate what we said on the call about the timing, again, the update in the first half will show progress on enrollment. We'll share some more mature safety profile data since the one that we provided back in March. And we'll provide some patient cases so that you can get a sense of the efficacy that we're seeing. And then in the latter half of the year, again, the goal is more comprehensive data set, double-digit patient numbers across the tumor types, ideally at the go-forward dose, looking both at mono and combo data sets. So, you know, we can make some decisions at that point looking at all of the variables that were just mentioned.

Yeah, in the first half data release, we'll have more data on PK. And as Michael mentioned during his prepared remarks, this is the first time we've disclosed that in the U.S., we are seeing better PK at 900 than 600. And that's both AUC, which is kind of, I guess, the standard measure folks would normally use. But because of the resident's time or time on target being about 24 hours, We actually think C-max matters a lot. So it can come out of the blood and still be actively blocking the target. And John Pachter's presented some really elegant work at an AACR RAS meeting recently. And so we think by seeing that PK going up with the dose, we think it just further strengthens the case for pushing that 900 milligram dose, especially since we are seeing that it's tolerable.

Thank you. Thank you.

Our next question comes from Andres Maldonado with HC Rainright. Your line is open.

Hi, guys. Thanks for taking the question and congrats on the progress. Two for me for 7375. First, So in the non-small cell lung cancer, you know, you're including an asymptomatic untreated brain metastases cohort. So curious there, you know, is the goal mainly to show systemic activity in a difficult subgroup or is there a potential to, you know, do you guys think you have enough CNS exposure to support a differentiated intracranial profile that extends beyond that tissue type? And then second question, kind of a macro question, So, you know, earlier this quarter, we saw a Pan-RAS program report a grade 5 pneumonitis, you know, given the historical trends also seen with approved G12C. You know, how should we be thinking about these events, you know, through the lens of an on-off G12D or other strategies targeting G12D? Thank you very much.

Michael, you want to take those?

Sure. Sure. So first on the question of the brain mets, the systemic activity of the drug will be in lung cancer generally is being evaluated now at 600 in the ongoing phase one, and we will be doing the 900 in the phase two, as you see, as you saw from the deck that we had along with the prepared remarks. There's a separate cohort because obviously when you're trying to ascertain the value of the drug, systemically, you tend not to pick patients with metastatic brain disease. That said, lung cancer frequently goes to the brain, unlike colorectal and unlike pancreatic cancer. And so in lung, it's especially important to try to see if there's substantial brain activity. The drug does penetrate the brain. I believe Genfleet reported that two out of the five patients that they had who had asymptomatic brain mets had systemic responses to the drug. We haven't been able to ascertain exactly how much the brain mets may have shrunk, but the brain mets clearly did not. uh progressed because they wouldn't have been responsive if they had so this cohort of about 25 patients will be tweeted at 900 which is a higher dose than gen fleets able to obtain to see if we can control the brain mets and you all know about osomertinib and some of the other amazing therapies that also cross the blood-brain barrier and and really can help these patients do very well over time by preventing or treating uh brain mets so that's that's a starting point for potential for this drug that may differentiate it from others. To reemphasize what Dan said, the fact that we're able to deliver such good systemic levels that are very tolerable so far with the 900 gives us a good shot at being able to drive enough of the drug into the brain and do something about this. As far as pneumonitis is concerned, we have not seen any cases of pneumonitis that were believed to be caused by the drug. I believe that they... that we may have a treatment unrelated pneumonitis case in a patient who already received radiation and it was thought to be a radiation associated, but it was grade one and it had zero impact at all on anything we've seen. We've certainly not seen any kind of pulmonary symptoms with our drug that give us any pause. That said, You know, we'll be treating a large number of patients with previously treated lung cancer, many of whom have received chest field irradiation, many of whom have had one or more infections, all of which predispose you to downstream lung events. We're obviously hopeful we're not going to see that. And lastly, we do not believe, based on our tox studies, there's any drug-related risk of pneumonitis, but that remains to be seen. But nothing important so far.

Okay. And just to amplify Michael's comments about pneumonitis, we do have access to the entire PV database of Genfleet. And, you know, when we heard these events with some of the other drugs, we did a deep dive. And so his comments are informed by that work that's been done.

Thank you. Thank you. Our next question comes from

Yuan Ji with B. Raleigh, your line is open.

Thank you for taking our questions. Maybe one question on the combination of 7375 plus EGFR inhibitors in the PDAC indication. So with this incremental addition of EGFR inhibitor, which normally patients cannot get because of baseline KRAS notation, what kind of incremental efficacy you guys are looking to justify the addition of this agent, considering, you know, the safety liability with this EGFR inhibitor? Thank you.

Michael, you want to take that one?

Sure. There's two components to this. One is the overall response rate, of course, and the second very important one is durability. It is, we do believe, and we have some early data to could support that hypothesis, that we could deliver a higher response rate. We, it's too early yet to say whether we would have a increased durability of response. That said, the mechanism of action of cetuximab is to specifically block not only a growth pathway, it's an accessory growth pathway for sure for RAS-driven cancers. It's not the primary one, but when you block RAS in these cancers, including pancreatic and colorectal and probably some of the other gastrointestinal tumors, the EGFR pathway becomes much more important and blockade of that can be helpful again upfront, but also to prevent the development of resistance and running growth pathways through the EGFR pathway. So this could have impact on both sides of this. We will know fairly soon what kind of incremental we'll have. I can't give you a real number. I think what we'd like to do is say that if There are probably patients who would benefit from cetuximab from the get-go. We don't know who they are. And there'll be other patients who might benefit it from down the road, you know, after, say, eight or nine or 12 months on our drug. If they started to develop resistance, one could imagine adding cetuximab. We think that this development plan that we... we expect could support accelerated approvals could lead to availability of this combination regimen, maybe not up front in everybody, but certainly as an option for patients if they start to see progression of their tumor, as well as for some patients up front. So I think this provides a lot of flexibility. This is not an option for most of the pan-RAS inhibitors because the strong concerns about added rash here. And I think for the 40% of patients who have, you know, who have PDAC that's G12D and the 20% of patients that have colorectal cancer that's G12D, that this could be a really important addition either up front or down the road.

Thank you.

Thank you. Our next question comes from G. Mukherjee with BTIG, your line is open.

Great. Thanks for taking the question. Two from me. You certainly mentioned that 900 mg is looking like a very suitable go-forward dose. but was just wondering if you could elaborate a bit further on why this hits the sweet spot. Looks like 1,200 mgs is certainly still under evaluation. Was there some limiting factor with that dose perhaps? And then the second question was just related to the target studies. I think you've definitely mentioned that these are designed to be supportive of approval, have you reached some degree of alignment with the agency on what the bar for approval is? Looks like ORR is a primary endpoint across several of the studies. Is there some threshold you need to exceed? Any details there would be helpful. Thanks.

Michael, you want to take those?

Sure. So just to be really, it's a simple answer for 1,200. The capsules that we have right now, I'm sorry, the pills that we have right now are 100 milligram pills. Asking patients to take nine of these to give you 900 mg is the upper limit of what they can really handle in one swallow, if you will, or one session, if you will. For the 1,200, we're going to a split session of six and six, split by about 30 minutes because we ask people to take it with food and plenty of water and so on to make sure it gets down there. and everything. So it's just impractical to go much above 1,200 with the current pill size. That said, we are certainly in the midst of constructing larger pills, which we'll update you guys on when we have that to a point where we think it's real. And hopefully, we don't expect to be marketing this as 100 milligram pills, we expect to be marketing it with higher pill sizes so that we don't have to give people that much. So it's pretty simple and straightforward. Once we have the larger pills, depending on what we see with 1200, we may consider going higher. But right now, 1200 is it. As far as FDA's threshold, I mean, we have not had any discussions with them specifically about what this is. But thankfully, and I think the oncology division of the FDA has been superb about this, particularly for molecularly defined subsets of cancers. They have routinely approved drugs as low as 25%. Typically, the 25 to 30% ORR range is what's approvable as a single arm study, provided there is sufficient durability. You know, if you go to ASCO, most experts will tell you they want to see at least six months duration of response. We all keep in mind that that six months plus the month and a half minimum it takes to get to a response. So you're talking seven and a half to eight months at least on the drug, which for these kinds of tumors, is pretty impressive, particularly in heavily pretreated patients. I think those are kind of the thresholds you should be thinking about, 30% on the ORR number and six months durability. But those are general numbers, and it's always a review issue with the FDA.

Thank you. Thank you.

And our final question comes from James Malloy with Lawline School Partners. Your line is open.

Hi, this is Matt on for Jim today. Thank you guys for taking our questions. Just two from us. In terms of the launch for ANF, the reimbursement for KRAS, KRAS undefined and KRAS wild type, is that continuing at similar rates from previous quarters?

Yes, we've seen no change.

Okay, excellent. And then do you guys have any anecdotes from treating doctors whose patients have been on treatment for over eight or nine months at this point? And if you could share, that would be very helpful.

Um, sure. I mean, it's anecdotal at this point, you know, given the fact, you know, we've only been out for, you know, just a year now. Um, but there are patients that have done quite well that are both wild type and mutant. And we also, you know, continue to interact with the sites on ramp 201. And, um, I recently spent some time with a patient that's been, um, never achieved a PR with stable disease, but had, um, really transformational change in her ability to do things. She went from not being able to vacuum her living room to running a 5K and has been on our drug for, I believe, three to almost four years now. And so we do have a lot of anecdotal information. Even going back to the frame study, we had a number of patients staying on for a long time. So, you know, we do think when it's the right patient that we'll recapitulate what we saw in the clinical trial. As you may recall, in RAMP 201, we had patients from anywhere from one prior therapy to 10 prior therapies. And it tends to be less, I think, you know, of course, the more prior therapies you have, the more challenged the patient has. But I think the big difference in the real world versus the clinical trial would be performance status. In most clinical trials, you're limited to performance status 01, and obviously in the commercial setting, you take anybody who wants to come on the drug, and even though we did hear instances of patients going on one cycle and coming off, and then you can say, well, they probably shouldn't have gone on the therapy, we've also heard anecdotal stories of patients that were pulled out of hospice, put on the drug, and did well for a number of months, and got a number of months with good quality of life they otherwise wouldn't have had. And so, you know, those are great stories to hear, and we continue to monitor those. And, you know, we're very excited about the franchise. You know, I think we've uncovered some things from seasonality, plus, you know, you learn as you go through the launch, and I think we've made some course corrections that it may take. you know, a couple of months to see the full benefit of, but I will say with confidence, we already are sure that we will see an increase from Q1 to Q2 that was bigger than the Q4 to Q1.

Great. Well, thank you guys for the caller, and thanks for taking our questions. Congratulations.

Thanks for the questions. Thank you. This concludes today's conference call.
