Dr. Maky Zangeneh, President and Co-Chief Executive Officer, Summit Therapeutics: Thank you, Dave. Good afternoon, everyone, and thank you for joining us today. I’m very proud of Team Summit’s ongoing accomplishments and the growing positive data sets and support around ivonesimab, a PD-1/VEGF bispecific, our lead investigational asset. We are a highly focused, mission-driven, patient-first company with a mission to make a significant difference in improving the lives of patients suffering from cancer. Our team is growing rapidly as we expand our clinical development plan and prepare for commercialization in anticipation of a decision from the FDA on our BLA near the end of this year. We have announced a few significant events today, starting with the update related to our HARMONi-3 study.

Last quarter, we announced our HARMONi-3 phase III trial evaluating ivonesimab plus chemo as first-line treatment for patients with squamous and non-squamous, non-small cell lung cancer, was amended to have separate analysis by squamous and non-squamous histologies for primary endpoints of PFS and OS for each cohort. The squamous cohort was planned to complete enrollment in the first half of 2026, followed by the non-squamous cohort in the second half of this year. As announced today, we have now completed screening patients for the squamous cohort of the HARMONi-3 study, and the last patient will be randomized in the next couple of weeks. We have amended our statistical plans to now include an interim PFS analysis for our squamous cohort, and we are planning to conduct the interim PFS analysis during the second quarter of 2026. Overall survival will be immature at the time of this analysis.

Therefore, we may not have overall survival results to communicate at that time. As you recall, we initially included PFS as a primary endpoint in this study upon the readout of HARMONi-2, comparing Ivonesimab to pembro in PD-L1 positive frontline lung cancer patients, which showed a highly statistical significant and clinically meaningful benefit in PFS with a hazard ratio of 0.51 and a median improvement in PFS of over 5 months. This point was later validated with HARMONi-6, showing that there was a substantial PFS benefit when comparing Ivonesimab plus chemo versus a PD-1 inhibitor plus chemo with a hazard ratio of 0.60.

Two Phase 3 studies conducted by Akeso in China in frontline non-small cell lung cancer demonstrated a 40%+ improvement in PFS for the ivonesimab, or both the HARMONi-2 and HARMONi-6 PFS results were based on the planned interim PFS analysis of each study. By adding an interim PFS analysis, we opened the door to an earlier discussion with the health authorities for our multi-regional Phase 3 study. The final PFS analysis, if applicable, and an interim analysis for OS, is planned to be conducted in the second half of this year, consistent with previous guidance. For the non-squamous cohort of HARMONi-3, we continue to expect enrollment to complete in the second half of this year and to reach the pre-specified number of events for the final PFS analysis by the first half of 2027.

There are several meaningful moments upcoming related to these two cohorts, each of which are independent from each other, like two separate studies in one protocol, where 2026 will be pivotal to providing additional clarity to expand the reach of Ivo to a broader population of lung cancer patients. Additionally, we announced today the first update to the Ivo Phase III clinical trial program, which will continue to expand throughout 2026. ILLUMINE, a new Phase III study in PD-L1 positive frontline head and neck squamous cell carcinoma, will be sponsored by GORTEC, a French cooperative group dedicated to head and neck oncology, with initial enrollment expected to begin early next quarter. The study intends to evaluate both ivonesimab monotherapy and in combination with Ligufalimab, a case of proprietary anti-CD47 monoclonal antibody against monotherapy pembro in this 3-arm randomized study.

Approximately 780 patients are intended to be enrolled across the three arms in multiple countries in Europe and in China. We may consider potentially expanding the study to include U.S. sites as well. phase II data supporting the potential use of ivonesimab in this patient population was previously presented at ESMO 2024, where ivonesimab, in combination with Ligufalimab, demonstrated an objective response rate of 60% in 20 patients, with median PFS of 7.1 months after median follow-up of 4.1 months. At the time of this analysis, no patients receiving ivonesimab plus Ligufalimab discontinued treatment due to the treatment-related adverse events. The data generated in phase II is encouraging in light of existing standard of care, Akeso is also running a single-region phase III trial in this population in China.

Turning to our clinical collaboration with Revolution Medicines, today, we announced the first patient has been dosed in the collaboration’s initial clinical trial. As a reminder, ivonesimab is being evaluated in combination with three RAS(ON) inhibitors, including daraxonrasib, a multi-selective RAS inhibitor, zoldonrasib, a KRAS G12D selective inhibitor, and elironrasib, a KRAS G12C selective inhibitor, across multiple solid tumor settings with RAS mutations, including pancreatic cancer, colorectal cancer, and non-small cell lung cancer. Finally, as we announced last month, we entered into a clinical collaboration with GSK to evaluate ivonesimab in combination with GSK’s novel B7-H3 antibody-drug conjugate in multiple solid tumors. The initial study under this collaboration is expected to begin dosing patients in mid-2026. Let’s now take a step back and look at ivonesimab accomplishments to date. There are many to list. We are just highlighting some of them.

Ivonesimab has read out four Phase III clinical studies to date, all four of which have had positive data, leading to two approvals in China so far. At this time, a total of 15 Phase III trials have been announced, currently ongoing, or have read out in multiple tumor types. 44 clinical trials have been initiated since 2019 between Summit and Akeso, evaluating ivonesimab in a variety of solid tumors. When considering investigator-initiated and collaborative studies, a total of 142 clinical trials are now listed on ClinicalTrials.gov. The enthusiasm demonstrated by investigators around the world to generate data and seek positive signals for patients facing high unmet medical needs really speaks to the opportunity and optimism surrounding ivonesimab. Together with our partner, Akeso, we have enrolled over 4,000 patients in either Summit-sponsored or Akeso-sponsored clinical trials across the world.

Commercially, in China, over 60,000 patients have received ivonesimab based on 2 approved indications by the NMPA in non-small cell lung cancer, according to our partners at Akeso. A third indication, based on the positive HARMONi-6 study in frontline squamous non-small cell lung cancer, is currently under review by the NMPA in China. I wanted to make sure this point is not missed. 4 phase III trials evaluating ivonesimab have read out to date, and all 4 with positive data readouts. This represents the only phase III readout that we have seen in the PD-1/VEGF bispecific class to date. These positive trials are supported by the differentiated mechanism of action of ivonesimab. Here is the current ivonesimab development plan across Summit and Akeso.

In total, there are 15 randomized Phase 3 trials, 4 of which are global Summit-sponsored studies in non-small cell lung cancer and colorectal cancer, 1 of which is a multi-regional, regional cooperative group study announced today, and 10 of which are being enrolled by Akeso in China in a variety of solid tumor types, including lung, breast, head and neck, BTC, pancreatic, and colorectal cancers. Additionally, Akeso is also currently enrolling multiple Phase 2 trials evaluating ivonesimab in other tumor types: ovarian, gastric, HCC, and others, including non-metastatic settings. Through our partnership with Akeso, we continuously compile a substantial amount of data, allowing us to make faster, more informed decisions, fueling the rapid expansion of our global development plan. Focusing on our pipeline at Summit, we have 4 global Phase 3 trials completed or ongoing.

HARMONi, which read out positively last year, HARMONi-3, HARMONi-7, HARMONi-GI3, all three of which are currently enrolling and progressing nicely. The HARMONi trial evaluated ivonesimab plus chemo against chemo-alone as treatment for EGFR mutant non-small cell lung cancer after TKI therapy, a population of significant unmet need with few available treatment options. We submitted a BLA filing last quarter, seeking approval in this proposed indication, and in January, we announced the U.S. FDA’s acceptance of the filing and a PDUFA target action date of November 14th, 2026. As previously disclosed, the FDA noted that a statistically significant overall survival benefit is necessary to support marketing authorization in this setting.

Considering safety and efficacy profile of the current FDA-approved options to patients in this setting, the positive, regionally consistent results of this phase III multi-regional study, as well as discussions with Key Opinion Leaders and physicians who have administered ivonesimab to patients, we believe that ivonesimab is a potential treatment option with a favorable benefit-risk profile. In anticipation of potential approval in Q4 of this year, we continue to ramp up commercial capabilities in preparation for potential launch. HARMONi-3 is evaluating ivonesimab plus chemo against pembro plus chemo in frontline metastatic non-small cell lung cancer. This patient population represent a significant unmet medical need with nearly 100,000 patients in the United States alone, as this trial covers frontline non-small cell lung cancer patients without genomic mutations, irrespective of histology or PD-L1 status. I spoke a minute ago about the recent changes to this pivotal study.

For HARMONY-07, the study is evaluating ivonesimab monotherapy against pembro monotherapy as frontline treatment for patients with non-small cell lung cancer that have high PD-L1 expression levels. HARMONY-07 continues to enroll well, and we look forward to providing additional updates in the future. Finally, last quarter, we initiated and began enrolling patients in HARMONY-GI03, evaluating ivonesimab plus chemo compared to bev plus chemo in first-line therapy in patients with unresectable colorectal cancer. Our decision to expand into colorectal cancer was driven by encouraging phase II data published at ESMO 2024 and subsequent continuing enrollment in this phase II study to China and the United States with additional chemotherapy regimens. This data set allowed us to make an informed decision to move forward in CRC, specifically with the FOLFOX chemo combination.

We look forward to providing further updates on the phase II data set later this year, as well as the HARMONi-3, HARMONi-GI3 study as the trial progresses. Looking beyond our own sponsored trials, we are expanding into additional settings with multiple collaborations and other groups. We have the phase III ILLUMINE study, sponsored by GORTEC, evaluating ivonesimab in head and neck cancer that I spoke to earlier. With respect to novel-novel combination, we announced that the first patient was dosed this quarter in our collaboration with Revolution Medicines to evaluate ivonesimab in combination with 3 novel RAS inhibitors across multiple solid tumor settings. We are excited to learn about the opportunity and potential to improve patient outcomes with ivonesimab combined with these novel targeted therapies and promising molecule.

This collaboration is intended to evaluate ivonesimab in combination with one or more of RevMed RAS(ON) inhibitors in pancreatic cancer, colorectal cancer, and non-small cell lung cancer. This collaboration has an opportunity to be mutually beneficial to both Summit and RevMed by leveraging a combination of potential next-generation assets that individually have promise in each setting, and this may have high promise for patients with RAS mutant cancers. In our GSK collaboration, evaluating ivonesimab in multiple solid tumor settings in combination with their B7-H3 ADC, we expect the trial to initiate in mid-2026. This is another example of promising targets seeking to significantly advance outcomes in settings where both Ivo and B7-H3 ADCs have shown promise. We have over 60 ISTs that we intend to support in various stages of development.

Of these, 15 are currently enrolling, 5 of these in collaboration with MD Anderson, and Ivonesimab has now been featured in over 45 publications, presentations, and posters. Collectively, these trials enhance and inform our own clinical development activities as we learn more about new settings where neither we nor Akeso have had the opportunity to explore yet. Tremendous interest, interest in ISTs is a testament to the enthusiasm we have heard from many investigators as they consider the potential opportunity that Ivonesimab presents across multiple tumor types. Over the past 18 months, we have seen 4 positive randomized phase 3 trials, including the first and only phase 3 trials to compare positively against anti-PD-1 therapies. Each of these studies represent a benefit either over a PD-1 inhibitor or in setting where PD-1 inhibitors have failed to achieve a benefit in either PFS or OS.

Akeso’s HARMONi-2 PFS results showed ivonesimab monotherapy as superior to Keytruda in frontline non-small cell lung cancer. These results represent the first time any therapy has achieved a clinically meaningful benefit over Keytruda in randomized Phase III trials. In April of 2025, Akeso announced that HARMONi-2 achieved a clinically meaningful overall survival hazard ratio below 0.8 at this early look. Moving to Akeso’s HARMONi-6 frontline non-small cell lung cancer study in patients with squamous histology, results were announced at ESMO 2025, demonstrating ivonesimab with chemo was superior to PD-1 plus chemo in PFS. With this result, HARMONi-2 and HARMONi-6 represent the first and only known regimens to achieve a clinically meaningful benefit, replacing an anti-PD-1 regimen. In EGFR mutant non-small cell lung cancer, both Akeso’s HARMONi-A trial and our own global HARMONi trial achieved positive, consistent results.

In HARMONi, a positive overall survival trend was observed with hazard ratio of 0.79, barely missing statistical significance. In a subsequent analysis in September 2025, with longer-term follow-up on Western patients, ivonesimab plus chemo showed a favorable trend in the overall survival, with a hazard ratio of 0.78 and a corresponding nominal p-value of 0.0332. In HARMONi-A, Akeso’s final overall survival analysis showed ivonesimab plus chemo achieve a statistically significant hazard ratio of 0.74, with a p-value of 0.019, supporting a treatment profile where OS does not degrade, but rather improves over time in this setting. Turning to our market opportunity, the value proposition is clear. Ivonesimab on its own has the potential to be a platform blockbuster drug.

Additionally, novel, novel combinations with Ivo could bring potential improvements over current standard of care, which could expand market opportunity further. Ivonesimab is well positioned to make a significant impact across the solid tumor treatment landscape. Between checkpoint inhibitors and anti-VEGF therapies, TD Cowen and others estimate the total addressable market to be in excess of $100 billion globally. Yet, these estimates still do not include the full impact Ivonesimab could have as it has already shown promising data in multiple tumor types where checkpoint inhibitors have not been effective, including EGFR mutant non-small cell lung cancer and PD-L1 low triple-negative breast cancer.

Ivonesimab differentiated profile support its platform potential across multiple indications, many of which could be blockbuster opportunities on their own. We have a very exciting year ahead. Here are some of the upcoming milestones we expect to reach in 2026 and into the first half of 2027. Our global clinical studies pipeline will continue to expand. We will provide further details in 2026 as we begin studies in new settings and indications. This will include additional novel, novel combinations, as well as the new phase III studies that we intend to launch in 2026. The first steps with respect to this expansion came today with the announcement of the cooperative group-led ILLUMINE-1 phase III clinical study in head and neck cancer. We will continue to expand upon the details of our clinical development plan throughout 2026, including sponsored studies.

With today’s HARMONi-3 update, we anticipate an interim PFS analysis for the squamous cohort to occur next quarter. Final PFS and interim OS data are expected in the second half of this year. In the HARMONi-3 non-squamous cohort, we expect to complete enrollment this year. We anticipate final progression-free survival data in the first half of 2027. As already discussed, we are looking forward to a potential first approval for ivonesimab in the US around our November 14th PDUFA date based on our HARMONi BLA filing. Now, I will turn the call over to Manmeet to provide a financial and operational update for the quarter. Manmeet?

Manmeet Soni, Chief Operating Officer and Chief Financial Officer, Summit Therapeutics: Thank you, Mikie. Good afternoon, everyone. On the financials front, let me start with our cash position. We ended the year 2025 with a strong cash position of approximately 713 and $13.4 million. To remind everyone, currently we have no debt. Turning to operating expenses, I will provide details on both GAAP and non-GAAP numbers. You can refer to our press release issued this afternoon for a reconciliation of GAAP to non-GAAP financial measures. As a reminder, non-GAAP expenses exclude stock-based compensation expenses. Total GAAP operating expenses for the fourth quarter of 2025 were $225 million, compared to $234.2 million for the third quarter of 2025.

This decrease in GAAP operating expenses was primarily due to the lower stock-based compensation expense of $19.1 million. This was offset by an increase in our clinical trial-related spend of $8.8 million. Overall, our non-GAAP operating expenses during the fourth quarter of 2025 were $113.3 million, compared to $103.4 million for the third quarter of 2025. This increase in non-GAAP operating expenses was primarily related to an increase in R&D expenses related to HARMONi-3 and HARMONi-7 trials. As you will note, we have been very efficient and disciplined in controlling our G&A spend.

Our total GNS spend, excluding stock-based compensation expense, has been approximately $43 million for the full year 2025, with a run rate of approximately $10 million-$11 million per quarter in 2025. On the operations front, I’m extremely proud that Team Summit has been able to accelerate the enrollment of 600 squamous patients ahead of our planned timelines, which will allow us to have interim readout by second quarter of 2026. With the acceptance of our BLA with FDA, we have accelerated our commercial readiness activities to prepare for our potential commercial launch of EGFR mutant non-small cell lung cancer post-TKI therapy. With respect to manufacturing and drug supply readiness, we have successfully transferred and validated the production process of avanusmap to a US-based manufacturer. With that, I will hand it back over to Dave.

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Thank you, team. We will now see if there are any questions that our team can help answer. Operator, if you could please open the line for questions.

Astica, Analyst, Unknown0: Thank you. We will now begin the question and answer session. If you have dialed in and would like to ask a question, please press star one on your telephone keypad to raise your hand and join the queue. If you would like to withdraw your question, simply press star one again. We’ll take our first question from Salveen Richter at Goldman Sachs.

Astica, Analyst, Unknown5: Hey, this is Mark on for Salveen. Thank you so much for taking our question, congrats on the quarter. Can you talk about what drove the decision to include the interim PFS analysis for HARMONi-3 for the squamous cohort, also frame expectations for both the initial data in the second quarter and the potential final PFS analysis and interim OS in the second half? Will we see curves in addition to the top-line data, now, given the split, do you expect that OS could reach that statistical significance by that final PFS analysis time?

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Thanks, Mark. Appreciate the question. This is Dave. We decided to amend the protocol for the HARMONi-3 study by including an interim analysis for the, for the PFS primary endpoint. If you recall, we previously amended the HARMONi-3 study in order to add PFS as a primary endpoint, in addition to overall survival. The reason for the addition of PFS as a primary endpoint was based on the results of HARMONi-2, which showed the large PFS delta that Mikie spoke to, a hazard ratio of 0.51, comparing Ivo to monotherapy member of lung cancer patients. This was then seen again in, in the HARMONi-6 data. This would allow for an earlier discussion with the agency based on the PFS primary endpoint, and now an interim PFS.

It’s really about accelerating the timelines with respect to the data based on two interim readouts from our partners at Akeso in studies in lung cancer. With both studies remaining or reading out positively, the overlap and the indication with respect to HARMONi-6 that gives a strong indication in terms of the opportunity that exists here with Ivo plus chemo versus a PD-1 plus chemo here. What I would say with respect to your question on survival, and I think Mikie emphasized this point a minute ago as well, overall survival will be immature at the time of the interim PFS analysis.

In terms of disclosure, with respect to when that will take place, we plan to run the analysis in the second quarter, and then ultimately from there, what gets disclosed will be determined based on output results as well as, you know, traditional major medical conference guidance, depending on how results are read out one way or the other. With respect to your final question on final PFS interim OS, that remains no real change in timing. That’s the second half of this year. Again, we’re not really guiding, and we don’t really comment historically on our expectations with respect to results.

You know, we obviously are encouraged by Ivonesimab’s phase 2 data, that the phase 3 data that took place in HARMONi-6, and so we really, you know, are looking to continue to, you know, follow in those trends, but don’t necessarily guide specifically with respect to our expectations numerically, if you will.

Eric Schmidt, Analyst, Cantor: Excellent. Thank you.

Astica, Analyst, Unknown0: We’ll go next to Yigal Nochomovitz at Citigroup.

Astica, Analyst, Unknown3: Hey, great. Thank you very, very much for taking the questions and for the comprehensive, update, Maky and team. Just to kind of press further on this question around this interim PFS in the second quarter now. It, it sounds like what you’re saying is that, you know, this is based on the optimism from HARMONi-2 and HARMONi-6, but I just want to check, was there anything specific that you saw in HARMONi-3, you know, with respect to an event rate that’s faster or other new piece of information that increased your confidence in doing this interim now in the second quarter? Or is it, is it really just a, a question of, you know, providing this update sooner to accelerate development, you know, based on, as you pointed out, what you, what you saw with HARMONi-2 and HARMONi-6? Thank you.

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Yeah. Thanks, Yigal, for the question. It, it’s really a data-backed decision, as we mentioned with respect to interim readouts for HARMONi-2 and 6, and then obviously the significant overlap in, in setting with HARMONi-6. I would also reemphasize, we, we are not changing the timing, in terms of, you know, guiding towards final PFS expectations and then the interim OS, so no, no change there from events. I’ll, I’ll let Alan provide more commentary as well.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: Yeah, Yigal, I think what you said, it’s the latter. Remember, this study was designed way back in 2023, right? Since then, we’ve had the HARMONi-2 and the HARMONi-6 readout. Our mission has always to been, bring this very important medicine, which we think is a game changer, to patients as soon as possible, right? I think the HARMONi-2, and now the HARMONi-6 data gives us growing confidence. Granted, both of those studies read out on an interim PFS, which was very dramatic, and PFS is a surrogate endpoint, so there’ll have to be some regulatory discussion, but we’ll need to look at that data before we can make those decisions. But again, I think this is an opportunity to bring patients faster.

Astica, Analyst, Unknown3: Okay. At this point, are you providing any other details with respect to the alpha spend or the number of events that are triggering this interim in the second quarter?

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: No, nothing in terms of a statistical plan at this point has been provided, neither for the interim PFS nor the final. You know, we have provided, you know, approximate sample sizes for both cohorts and then obviously the primary endpoints of both PFS and OS.

Astica, Analyst, Unknown3: Okay. A totally separate question. I just want to, you know, comment or ask about Ivonesimab. You had the data in, in ESMO in 2024. What do you know about contribution of components with respect to ivonescimab and Ligufalimab? Is there evidence to suggest synergy, or, or, or not? Is this just an additive effect? If you could just spend a little bit more time explaining, you know, the, the thinking scientifically to put those two together. I know the ESMO data was, was a little bit of time ago, and back in 2024.

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Sure, Yigal. Thanks for the question. If you recall from ESMO 2024, we showed data that was generated from our partners at Akeso, both in monotherapy, ivonesimab, as well as ivonesimab in combination with Ligufalimab, that, as MacKee explained, was Akeso’s proprietary CD47 antibody. That data was encouraging in both cohorts, but it did show an additional uplift that was seen with ivonesimab plus Ligufalimab. We’ve seen our partners at Akeso launch a phase 3 study with the combination in PD-L1 positive head and neck cancer. We’ve explored and have been encouraged by this data as it continues the phase II data continues to mature.

Part of the, the study being a three-arm study, with Ivo in one arm, Ivo plus Ligufalimab in the second arm, and then the, the control arm being monotherapy pembro. That will help answer definitively that question, with respect to, to contribution of components. The, the two cohorts within the phase II each were encouraging, there was encouragement from the cooperative group in GORTEC, and I’d like to obviously, you know, thank GORTEC for, you know, their enthusiasm in terms of the study. That’s, you know, what’s, what’s led to the progression here.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: Yeah, I would just add that, as Dave said, Yigal, that the data from ESMO showed that the combination of Ligufalimab and Ivonesimab was had no higher overall response rate than Ivonesimab alone. We’re excited to work with GORTEC, which is a premier cooperative group in head and neck cancers, they’ve designed a very rigid, clinically sound, scientifically robust study to demonstrate that. I think Maky’s comments in the script showed that. There are going to be Ivonesimab as one group and Ivonesimab plus Ligufalimab. You can demonstrate the contribution of components against the standard of care, pembrolizumab. I think that’s going to be very important.

Astica, Analyst, Unknown4: Thank you. Thank you.

Astica, Analyst, Unknown0: Next, we’ll move to Brad Canino at Guggenheim.

Brad Canino, Analyst, Guggenheim: Hey, afternoon. Congrats on the screening completion. For me, it’s not quite clear yet why adding the interim provides a benefit with regulatory discussions, because it seems like you’ll reach final PFS before any OS data, interim or final, and presumably you would need the OS to file anyway. Can you help square that for me? Sorry to beat the horse on this one.

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Great. Thanks for the question, Brad. I think there’s a couple of things in terms of what you said. First of all, you can’t really have a discussion with respect to data with the regulatory agencies without data, right? Part of, part of the interim analysis allows for the generation of primary endpoint-based data. You know, as we continue to mature that data, you’ll see also at, you know, no change in our guidance with respect to final PFS as well as interim OS timing in the second half of the year as well.

When you kind of combine those two points, it allows for the acceleration of the conversation, without much delay, you know, there’s several months in between, obviously, second quarter versus the second half of the year, but it allows for progressing that conversation, with the agency, with data in hand to allow for next steps.

Brad Canino, Analyst, Guggenheim: I guess when I hear this, and along with the regulatory strategy in EGFR mutant, should we read this as like a company’s evolving view that front-line lung could see approvals with just PFS benefits and only OS trends? Thank you.

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Yeah, I, I mean, I, I think there, you know, it’s a combination, right? It, it depends on the timing, right? It, the magnitude of the benefit is important, and then obviously there’ll be some contribution, in terms of, you know, overall survival trends, and I think that’s where we see, dual primary endpoints, in this study, and then across solid tumors, you see that, in several places as well. The, the studies, to be clear, are certainly powered for both primary endpoints, which is an important point as well.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: Brad, this is Manmeet. I think in other words, right, depending upon this earlier interim PFS data and the magnitude of the PFS, that will allow us a potential discussion with the FDA to accelerate our submission as we submit, right. OS may come and mature, and that is the path forward to accelerate providing this drug to patients much earlier.

Brad Canino, Analyst, Guggenheim: Okay, thank you.

Astica, Analyst, Unknown0: We’ll go next to Corey Kasimov at Evercore ISI.

Astica, Analyst, Unknown4: Hi, this is Josh on for Corey Kasimov. Thanks for taking our question. Our question is on the head and neck phase 3. Why opt to go through a co-op group here, and what signal will you want to see before committing to expanding into the U.S. here, and could it be used to leverage for a U.S. approval?

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Yeah. Hey, Josh, thanks for the question. A couple of points there. I think one, we’ve, we’ve talked a few times now in terms of expanding our phase III program more broadly. I think in some ways there’s an opportunity to work with some of the premier cooperative groups in terms of adding additional indications that we see promise in as well. This is one of those indications. There’s a highly competitive space in head and neck cancer, and we think there are multiple opportunities for patients in this setting, and we think ivonesimab presents a strong opportunity in, in particular, ivonesimab, and then potentially ivonesimab in combination with ligafilimab, right? Working with cooperative groups also expands the number of trials that are able to be performed ultimately.

It’s important that we are taking on as much opportunities as we can with respect to bringing ivonesimab to as broad of a set of patients who are impacted by cancer as we can. We, we think that that is a strong approach overall. It’s a strong cooperative group who’s run multiple studies as well, and they were, they were highly enthusiastic based on the data that’s been presented and obviously working with them since. As, as McKee emphasized earlier as well, it’s important to note that we do plan to continue to expand that phase III program in 2026.

I think we’ve been pretty clear that as we plan to launch additional studies, we would wait until we get to the readiness to launch, and we’d have FPI in sight. Part of this will be over the course of 2026, but this was an important concept that we had with respect to working with a highly enthusiastic cooperative group in a setting which they specialize, and it was an opportunity to really explore on a multi-regional setting, these two regimens, really, the monotherapy as well as the combination regimen.

Astica, Analyst, Unknown4: On it, anything, yeah, go ahead. Sorry.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: I was just gonna add, they approached us, right? They came to us. You know, head and neck is an unmet need. It’s not the largest unmet need in the PD-1/VEGF space, I think we are gonna, as Dave said, focus our resources on the largest unmet needs, and this one was convenient because they came to us, wanting to do a study. Yeah. Sorry, Josh, I interrupted you.

Astica, Analyst, Unknown4: No, no, thanks, Allen. I, I was gonna ask if there was anything specific you could give us on what may trigger like a U.S. expansion here?

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: ... Yeah, not, I, I don’t know that at this time we want to start disclosing specific details, but obviously we’ll get enthusiasm with respect to enrollment. There’s several countries in Europe who are enrolling in the study. Feedback from GORTEC as they operationalize the study. There’s also additional data being generated by our partners at Akeso in Phase III in China with respect to the setting. I think there’s a multitude of different... You know, and there is continuing maturity of the Phase II, obviously, as well. There’s multiple paths with respect to that, but nothing more specific there, Red, just at this point.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: Got it. Thank you.

Astica, Analyst, Unknown0: We’ll take our next question from Tyler Van Buren at TD Cowen.

Astica, Analyst, Unknown2: Hey, guys. Congrats on the squamous enrollment completion and the progress. Should we expect the HARMONi-6 OS data later this year? How about HARMONi-2 OS data as well? In general, given the upcoming HARMONi-3 OS data over the next year, can you just reiterate what gives you the most confidence that all the positive PFS data we have seen from the frontline lung cancer trials will ultimately translate to OS benefits in the frontline Western population or, or global studies?

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Appreciate the question, Tyler. I think, as we have said a few times, the HARMONi-2 and the HARMONi-6 studies are studies that are conducted by and sponsored by our partners in China and at Akeso. They have not necessarily guided in terms of looks on overall survival readouts at this point. It’s important to note again, HARMONi-2 is not necessarily powered for overall survival and was not powered for overall survival at all. That was a PFS primary endpoint exclusively. HARMONi-6 was also a PFS primary endpoint, but obviously a little bit larger in the sample size, over 500 patients.

I think the, the protocol for HARMONi-6 was, was published, and so that would appear at some point, you know, to look like 2026 is an event, but they have not guided more specifically to that. I think the, the second half of your question with respect to, you know, translation into HARMONi-3, and then obviously the confidence that we have, you know, with the PFS data translating to OS. I’d make a couple of points. I, I don’t think there’s a better analogy in terms of opportunity with respect to a randomized phase III study, you know, and in this case, in, in squamous non-small cell lung cancer, ivonesimab plus chemo versus PD-1 plus chemo, than a randomized phase III, you know, that was nearly identical, just run in China, right?

That was strongly positive. The PFS hazard ratio, you know, indicated a 40% improvement in terms of PFS, you know, reduction of risk and, and/or death. When we look at the translation from, you know, China to the global setting, we’re obviously very confident, and HARMONi helped enforce that with, you know, very consistent results with respect to OS, both from a median perspective as well as, as hazard ratio. I think the other thing is we step back. You know, we often talk about the question with respect to PFS and, hey, what’s the confidence level translating that into OS? At this point, 4 randomized phase III have read out, right? HARMONi-A was the first, and that was in China, the EGFR mutant non-small cell lung cancer after TKI.

That final PFS, final OS analysis was statistically significant, and that was displayed at Citigroup. The second was the HARMONi study. We’ve talked at length there with a very strong showing with respect to overall survival. The final analysis was not statistically significant. With longer follow-up time, given the delays in initial enrollment in the, in the follow-up time, differences between China and the US, we saw a nominal P value that was below any threshold with respect to, you know, what would be required for significance. We saw a P-value of 0.03.

When we look at HARMONi-2, the, the only readout we’ve seen thus far was the NMPA, the Chinese health authority requested, look, and that showed a, a, an OS hazard ratio of 0.777, comparing ivonescimab to Pembroke. At this point, HARMONi-6 has not even hit that point, and it’s still. That application’s in review, is, is our partners at Akeso have announced, and so there hasn’t been a look yet at overall survival. Of the four that have read out, three of those studies have shown some data towards OS. All of them have shown a hazard ratio of less than 0.8, which when we speak to KOLs, we speak to physicians globally, that’s kind of the, you know, generally agreed upon threshold for clinical meaning, clinical meaningfulness, if you will.

The amount of encouragement that we’ve seen with respect to OS is about as high as you can get with respect to the time that we’re at. I appreciate everyone’s, you know, focus on overall survival, but overall survival takes time in terms of the readout, and all of the readouts that we’ve seen to date have pointed in, in one direction, which has been highly encouraging. Hopefully, Tyler, a comprehensive answer to your question, but, you know, one that answers it.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: Tyler, this is Allen. I would just add from a clinical perspective, from the mechanics of the study, they’re not a crossover design. The standard of care for both arms is the same, right? The patients are blinded, so they don’t even know whether which arm they were on, so they should get balanced standard of care. If you start that standard of care in the second line or later line, five months later, because of the PFS benefit seen on, that should translate to a benefit in OS, right? It’s just such a large magnitude in delaying that next line of therapy.

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: That’s great. Thanks.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: Astica, your line is open. Please go ahead.

Astica, Analyst, Unknown: Oh, hi, guys. Thanks for taking my questions. I’ve got a question, more of a commercial question here. As you’re thinking about the commercial footprint, you’re gonna need for EGFR mutant non-small cell lung that you’re that you’re building off right now, how much of footprint could you would be usable for, for, for the broader for the broader squamous population? I’m assuming all of that. Then how much more would you have to add, add on top of that to address the broader squamous population? Then I have a follow-up.

Manmeet Soni, Chief Operating Officer and Chief Financial Officer, Summit Therapeutics: Hey, Astica, this is Manmeet, and I can take that question on commercial readiness, right? There are a lot of synergies, right? If you see our EGFR, and squamous and non-squamous all are coming from the non-small cell lung cancer, right? As you would know it, right, most of them are treated by similar physicians over there. Our footprint and synergies will come, right, pretty much. EGFR is a much smaller population base. Squamous gets over, like, 2.5-3 times bigger than EGFR, and then non-squamous comes, which is almost double of squamous, right? It keeps expanding, but it gets our foot into the door.

We will have to do a lot of education, a lot of, you know, learning from our setting, our basic infrastructure in next coming quarters. That will be the backbone of as we expand into squamous and non-squamous, because these are all similar physicians, same institutions.

Astica, Analyst, Unknown: Manmeet, so Manmeet, how, how should we think about, I guess, the, the, the ramp-up in your expenditure, for the FDA line item?

Manmeet Soni, Chief Operating Officer and Chief Financial Officer, Summit Therapeutics: We have been, like, pretty efficient over there. As I said, EGFR is the smallest one, right, to initiate. We don’t have to put a lot of expenditure, and the most of the expenditure will come, right, when we hire our sales teams over there. We have been already doing a lot of activities on the medical affairs front, which we initiated, right, last quarter, and those all are happening. I would say there will be expense, but that will come a quarter before the PDUFA, right? As you get into that, you hire more salespeople and other things. Other than that, we are already, you know, doing much of the activities and managing that right now very well.

Astica, Analyst, Unknown: Got it. Thanks for that. As we’re, I like that you guys are offsetting some of the development to these cooperative groups like GORTEC. Of course, these groups are going off a data that’s generated in China, also with the with novel agents that are not yet approved in the U.S. and Europe. I guess, how are you thinking about, when you think about these data conversion for U.S. submissions, how are you thinking about some of the regulatory requirements like Project Optimus, that might be required perhaps to be done before the phase 3 is started?

How are you getting these, these cooperative groups to kind of play ball with that and, and make sure that, that the data that they’re generating is gonna be applicable for a U.S. submission, too?

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: It’s a great question, Astica. Importantly, our partners at Akeso have started a phase 3 in China in this setting. That also speaks to the additional data that exists with respect to some of the work that’s been done in this setting. Also, there’s, there’s Project Optimus, there’s, there’s contribution of components which we spoke to earlier as well. Obviously, with the novel, novel opportunity here with Ivonesimab and Ligu, it’s important to show Ivonesimab as a monotherapy as well as Ivonesimab and Ligu combined. I think a lot of the concepts that you’re speaking to are something that’s, that’s permeating both in the US as well as Europe.

The cooperative groups are very familiar with, with those, thought processes of the, of the health authorities. So in general, that’s not something, that is of high concern in terms of pushback or, or anything like that with the, with the cooperative groups. That’s something that’s pretty well understood at this point.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: Yeah. Hi, Astica, this is Al. I just add to what Dave said, is that we’ve used Chinese data clearly to satisfy Project Optimus before, so that shouldn’t be an issue.

Astica, Analyst, Unknown: Got it. Thanks, guys.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: We’ll take our next question from David Day at UBS.

David Day, Analyst, UBS: Great. Thanks for taking my questions. On the HARMONi trial in second-line EGFR and also someone cancer, could you provide some additional color on the FDA interactions leading to the BLA submission? More importantly, anything to share on the FDA extent on the OS, how has that changed over time?

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: Yeah, this is Alning. Again, I think we’ve been very transparent that, you know, the, the study is positive with the PFS endpoint. We just missed OS because of delays in enrollment due to sort of post effects from the pandemic. The FDA was clear that they wanted to see OS to make this a filable package, and we said, "Look, we think the data are important." When we look at our data compared to other agents approved in this space, we think that this satisfies an important unmet need for patients. We wanted them to review the full package of the data. We submitted it, and they’ve accepted that filing, and they’re reviewing the data now.

David Day, Analyst, UBS: Got it. Okay, that’s helpful. Then just on the most recent collaboration with GSK, the B7-H3 ADC in combination with Ivo. So just it helps to understand a little more on the initial indication you’re exploring. We know that GSK is currently exploring the B7-H3 for n- small cell lung cancer. Is that an indication you think it would make sense for you to explore in combination with Ivo?

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Yeah, we’ve specifically talked about in our press release announcing the, the collaboration, small cell lung cancer, right? So that is a place. We’ve also been clear also that there’s multiple solid tumor settings, where we believe both B7-H3 as well as ivonescimab have shown promise.

There’s obviously a place where with the evolving landscape of small cell lung cancer, that that’s an important place for us to explore, and we think the B7H3 ADC, that GSK has, is, you know, very much showing a lot of the-- We’re not gonna go into details with respect to the comparisons we’ve done against the B7H3s across multiple companies, but it’s important that we, you know, we did look at that asset and feel that that was a very appropriate partner for ivonescimab with respect to collaborating in small cell as well as, you know, a couple other solid tumor settings.

Astica, Analyst, Unknown6: Thank you so much.

Astica, Analyst, Unknown0: We’ll move next to Mitchell Kapoor at H.C. Wainwright.

Mitchell Kapoor, Analyst, H.C. Wainwright: Hey, everyone. Thanks for taking the questions. With, with HARMONi under consideration from the FDA, could you walk through your high-level thoughts on pricing strategy, given the competitive landscape and EGFR non-small cell lung cancer, but also the benefit of Ivonesimab, what it could provide in future expansion indications?

Manmeet Soni, Chief Operating Officer and Chief Financial Officer, Summit Therapeutics: Hey, Mitchell, this is Manmeet, it’s very early to start talking about pricing. Pricing is dependent on, is finally decided, right, based on the final label you have and the indication which you are launching in. Obviously, EGFR is our first one, but we will not be commenting on the price. Obviously, as you see the other benchmarks, right, you can easily look at, right, how other second-line EGFR drugs are priced, you could see that there is big range, we have the potential, based on the benefit of Ivonesimab, to price it very well. As you also stated, right, in the long run, we have multiple more indications to come, so we’ll have to price it appropriately. More to come.

I think there is no decision or nothing to add over here right now.

Mitchell Kapoor, Analyst, H.C. Wainwright: Okay, fair enough. On, on those potential expansion opportunities, obviously, ivonesimab is kind of this pipeline and a drug opportunity, which is rare these days. What kind of gating items, you know, would, would, would be there to determine how fast you could initiate more trials? Is it additional partnerships or, anything that can determine, you know, the next steps you take? Are you watching Akeso’s next moves, or, or, you know, what, what’s helping you decide how fast to initiate additional studies?

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Yeah, it’s a great question, Mitchell Kapoor. I think I wanna emphasize one of the points that McKee spoke to, because I think sometimes it, you know, there’s a lot of really positive events that take place with Ivo, and, and sometimes, it’s important to slow down on a couple. Over 4,000 patients have been treated with ivonesimab just in clinical trial, clinical trials sponsored by either Summit or Akeso, right? This doesn’t include the over 140 total clinical trials listed on ClinicalTrials.gov at this point. This doesn’t inc-, you know, such as ISTs and whatnot. When we look at the amount of data generated by ivonesimab, there’s a significant amount of information that can be, you know, really well understood in, in several different settings. We’ve also...

You know, it’s important that our partners at Akeso have initiated 10 phase three clinical studies. Underneath that, you can see the amount of data that has been generated in terms of really understanding where ivonesimab can be successful. Obviously, there’s also a significant, you know, place where we can continue to explore, where maybe the prevalence of a particular disease in China is not necessarily as high as it may be in the US and vice versa, right? There’s a lot of overlaps with respect to the characteristics of those diseases. That’s important for us to be able to kind of translate that information across. Because there’s so much patient data, with respect to how patients have performed on ivonesimab, that really allows us to, you know, triangulate, if you will, the information.

We’re not running, you know, hey, we, you know, we’ve, we’ve been able to dose 30, 40, 50 patients with Ivo, and now it’s, it’s very encouraging, so we, we are trying to figure out how to move forward. There’s a plethora of information and data, you know, so much of it truly, highly encouraging in terms of what that opportunity can be. That really gives us the opportunity to really think through the different places, the different standards of care. It’s important to also consider what the standard of care is in some of these settings. How is that evolving? How is that evolving in the short term? How is that evolving by the end of what would be a phase III clinical study?

So we can really look at the information we have internally, what’s happening in the, in the market, to really, at the end of the day, what we’re trying to do is provide a medicine that improves outcomes for patients, right? That takes an ecosystem in order to do. Physicians need to be able to, you know, access, understand, and have clear you know, answers from that data. Patients need to be able to see what opportunities exist based on data and outcomes from trials.

When we look at the totality of the landscape across, you know, many of the tumor types that, you know, are sensitive either to immunotherapy, anti-angiogenic therapy, places where neither have been successful, but there’s an opportunity with Ivonesimab, we really can look at the totality of the landscape, the data generated, what physicians will, will need to see in a couple of years to really come up with the right answer. That’s why some of these even collaborative studies, or collaboration opportunities, rather, with RevMed, with GSK, that’s important. We’ll have more of those coming as well. When we look at the totality of what’s out there, it’s really important to consider, you know, each of those points. That’s why we really look to expand much further in 2026 as well.

Astica, Analyst, Unknown6: Yeah, Mitchell, and I want to just address a couple of your comments. You know, at JPM, McKee announced that we’re going to be doing multiple new phase III programs.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: ... We will, of course, continue to explore cooperative group studies and collaborations with external partners. You should expect more of those to come. Our, our, our strategy is not dependent on that. We will have sponsored studies based on the Akeso data and moving forward. You should expect more of those studies to come as well.

Astica, Analyst, Unknown1: Wonderful. Thank you, guys.

Astica, Analyst, Unknown0: Next, we’ll go to Eric Schmidt at Cantor.

Eric Schmidt, Analyst, Cantor: Well, thanks for taking my question. I wanted to go back to HARMONi-3 and beat the horse a little bit more. I’m wondering if you’ve had discussion with the FDA around what you think would be the maximum disclosable set of information, given you need to maintain the integrity of the trial. Do you think, for example, you might be able to give us hazard ratios or any other meaningful data at that time? Thank you.

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Eric, just to be clear, Eric, you’re speaking about the interim PFS?

Eric Schmidt, Analyst, Cantor: I am. Thank you, Dave. Yep.

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Yeah, no, I appreciate it, Eric. I mean, look, I, I think, yeah, and I think we, we kind of mutually addressed this across comments from Manmeet, McKee and, and myself a little bit earlier. It’s important that the analysis is run and then we see the analysis in terms of outcomes, in terms of what the next, you know, logical steps are, in that respect. Obviously, positive data, you know, requires, you know, contemplation with respect to major medical conferences as well. It’s we have, you know, several we’re, you know, opportunities, if you will, in, in, in terms of the data and what that readout will look like. As we get a little bit closer, we’ll be providing, you know, a little bit more clarity on what that looks like.

Obviously, we, we thought it was very important now to provide, you know, effectively an immediate answer with respect to the analysis being, you know, run in the second quarter, and then the amount of that disclosure in some ways depends on, you know, what both the data shows and what the next steps are.

Eric Schmidt, Analyst, Cantor: Yeah.

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Okay.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: Go ahead. I, I, I just wanna manage expectations here. You know, once we get the data, the most important thing is trying to provide this agent to patients as soon as possible. That requires a regulatory interaction, right? As a courtesy to them, we need to demonstrate to them first, right? You know, in collaboration with our investigators, we wanna present this at a major medical meeting. You know, unfortunately, you know, sort of a press release with curves for you guys as investors and analysts are, are not gonna be a high priority for us.

Eric Schmidt, Analyst, Cantor: Well, I guess my, my question was even just very specific to maintaining integrity of the final PFS readout from a regulatory standpoint, and whether even if you were able to give an interim PFS readout, that would be too great a disclosure, making regulators too uncomfortable. Do you have a view on that?

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Sorry, Eric, I’m not, I’m not sure we followed exactly what you’re-

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: I think what he’s saying is, Eric, correct me if I’m wrong, but what you’re saying is if we were to release top line interim PFS, would that impact the study scientifically in terms of unblinding it for the final PFS, right?

Eric Schmidt, Analyst, Cantor: Exactly. Thank you.

Dr. Allen Yang, Chief of R&D Strategy, Summit Therapeutics: Yeah, I, I understand what you’re saying. I guess I just don’t want to disclose too much about what we’re doing at this time. I understand your question. We’re, of course, gonna take that into consideration, you know, I just don’t want to disclose how we’re gonna do this right now.

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Yeah, I would say a couple of key principles, right? We’re, we’re never gonna do anything that puts at risk the, you know, the, the, the final analysis, if you will. I think part of this becomes an outcomes-driven response as well in terms of what, what that data shows to be able to, you know, provide the clarity and transparency, but also be able to, you know, maintain the integrity of the study itself, as well as the interactions with the health authorities.

Eric Schmidt, Analyst, Cantor: Okay. Thanks, guys. Appreciate all, all the updates.

Astica, Analyst, Unknown0: We have time for one more question, and we’ll take that question from Faisal Khursheed at Jefferies.

Faisal Khursheed, Analyst, Jefferies: Hi, thank you guys for taking the question. I wanted to ask on the FDA review for HARMONi. Have you guys had any interaction with the FDA since having the BLA submitted? Is there anything in the FDA’s stance changing on acceptability of PFS and read through of that to HARMONi-3?

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Yeah, thank, thanks, Faisal. I, I think we addressed most of this a little bit earlier. Yes, we have interactions with the agency. We don’t necessarily disclose, you know, you know, meeting by meeting discussions and whatnot. So what we don’t wanna do is, we’re, we’re not looking to leverage external sources in terms of, you know, pressuring the agency or anything like that. We have, we have confidence. Those discussions are intended to be confidential, so we’re not, we’re not necessarily giving step-by-step updates with respect to that. We have, we do have interactions with the agency, both for this study as well as, you know, other current studies and then, you know, potential future studies.

It’s important in terms of the totality of what we’re looking to accomplish with Ivonesimab, that we have the utmost respect for the FDA. I think that’s a, just a level-setting point. That becomes very important in terms of, you know, with the platform opportunity, if you will, for Ivonesimab. There’s a lot of studies with a lot of potential settings where Ivonesimab may bring benefit to patients, and we want to make sure that we have a strong relationship with the agency in order to do what. Our mission is really to bring Ivonesimab to be, to as many patients facing an unmet need as is possible in doing what’s right for ultimately patients, you know, facing cancer diagnoses.

Faisal Khursheed, Analyst, Jefferies: Understood. Thank you.

Astica, Analyst, Unknown0: That concludes our Q&A session. I will now turn the conference back over to Dave Gancarz for closing remarks.

Astica, Analyst, Unknown1: Hi, this is Bob Duggan. Not only is David correct in saying that we have a tremendous respect for the FDA, it is probably America’s most respected agency around the world for its integrity, the due diligence of its work, putting patients first, and we’re really honored to be reporting into them. Lastly, we’re also very impressed with our partner, Akeso. You know, Akeso has almost a few hundred million dollars of investment value in their ownership along with you all that are owners of Summit, and we’re happy that they chose to do that. We’re also quite pleased to see that, that, that, that time after time, when they introduce new drugs, they get through their own agency, they get clearances, they’re doing quite well.

It, if there’s any China lookalike, a Regeneron, it’s Akeso, just a fabulous company with great engineers, great scientists, and we’re pleased that they are the source of the bispecific tetravalent back in 2013. We’re proud to have that in-licensed and we’re making great progress with that. Thank you all. We look forward to updating you on our next call, unless there’s great late-breaking news in between.

Dave Gancarz, Chief Business and Strategy Officer, Summit Therapeutics: Thank you, everyone.

Astica, Analyst, Unknown0: This, this concludes today’s conference call. Thank you for your participation. You may now disconnect.
