Asthika Goonewardene

Asthika Goonewardene sought clarification on 'other options' for daraxonrasib in first-line non-small cell lung cancer (NSCLC) beyond Pembrolizumab plus chemotherapy, specifically asking about other PD-1s, mechanisms, or chemo-free options. He also asked if the Commissioner's Priority Review Voucher (CNPV) would be used for second-line pancreatic cancer (PDAC) once RASolute 302 data is available.

Answer

Chairman and CEO Mark A. Goldsmith clarified that 'other options' referred to the potential emergence of ivonesimab as a combination partner, alongside ongoing dose optimization and efficacy analysis of daraxonrasib plus Pembrolizumab plus chemotherapy. Regarding the CNPV, he stated that it was awarded based on second- and third-line data, making it logical to operate under the CNPV in the context of the second-line RASolute 302 data readout.

Asthika Goonewardene sought clarity on the 'other options' for daraxonrasib in frontline NSCLC, specifically if they include other PD-1s, PD-1/CTLA-4 combinations, or chemo-free regimens, and asked if Revolution Medicines plans to use its Commissioner's Priority Review Voucher for second-line PDAC once RASolute 302 data is available.

Answer

Mark Goldsmith, Chairman and CEO, clarified that 'other options' referred to evaluating ivonesimab versus pembrolizumab plus chemotherapy, with both approaches being pursued in parallel. He confirmed that the Commissioner's National Priority Voucher (CNPV) was awarded based on second- and third-line data and would likely be utilized for the second-line RASolute 302 data readout.

Asthika Goonewardene asked about expected resistance mechanisms for Diraxonrasib in NSCLC, whether they are similar to PDAC or new, and how this guided the choice of pembrolizumab and chemotherapy combination. He also followed up on whether requiring four months of chemotherapy in Resolute 304 helps select out borderline resectable patients.

Answer

Steve Kelsey, President of Research and Development, stated that NSCLC resistance data is not yet mature enough for public disclosure, noting potential differences from PDAC and CRC. He explained pembrolizumab selection is driven by its standard-of-care inclusion and evidence that RAS suppression enhances its effectiveness. Alan Sandler, Chief Development Officer, clarified that the four months of chemotherapy is standard of care, and patients must be pathologically completely resected (R0 or R1) to enter Resolute 304, which broadens access for borderline resectable patients if surgery is successful.

Asthika Goonewardene inquired whether Diraxonrasib resistance mechanisms in non-small cell lung cancer (NSCLC) are expected to mirror those in PDAC, if new resistance mechanisms are emerging, and how this influenced the choice of pembrolizumab and chemotherapy for combination. He also asked if the four-month chemotherapy requirement in Resolute 304 helps select borderline resectable patients.

Answer

Steve Kelsey, President of Research and Development, stated that NSCLC resistance data is not yet mature for public disclosure and that resistance mechanisms may differ from PDAC, making direct inference difficult. He explained that pembrolizumab selection is driven by its role as standard of care and evidence that RAS suppression enhances its efficacy. Alan Sandler, Chief Development Officer, clarified that the four-month chemotherapy in Resolute 304 is standard of care, and patients must be completely resected (R0 or R1) to enter, which broadens access for borderline resectable patients if surgery is successful. Mark Goldsmith, Chairman and CEO, added that standardizing chemotherapy duration ensures a uniform patient population.

Asthika Goonewardene asked about the timing differences in setting up community ATCs versus academic centers, the diversity within community settings, the utility of recent TANDEM real-world data for MSLs, and whether Q1 Proleukin reordering occurred after the February 1st price increase.

Answer

Dan Kirby, Chief Commercial Officer, expects a similar learning curve for community ATCs as for academic centers, noting community ATCs are closer to patients and accelerate treatment once financial reimbursement is confirmed. He confirmed MSLs reactively have the TANDEM real-world data, which is being submitted for publication. Brian Gastman, EVP of Transitional Medicine and Research, added that the TANDEM data validated clinical observations, showing better-than-trial responses. Dan Kirby clarified that wholesalers typically order before a price increase, so Q1 reordering would have occurred in advance of the February 1st price increase.

Asthika Goonewardene asked what proportion of the 70 active Authorized Treatment Centers (ATCs) have reached a 'steady state' of operation.

Answer

Interim CEO Frederick Vogt estimated that a very low number, likely 10% or less, have reached steady state. Chief Commercial Officer Dan Kirby added that even the most active centers (those with 10+ infusions) are not considered saturated, as the strategy is to drive more community referrals to these experienced sites.

Asthika Goonewardene of Truist Securities asked for more detail on the improving out-of-spec rate, questioning if it's driven by experienced centers improving or new centers performing better from the start.

Answer

Interim CEO Frederick Vogt explained that it is a combination of both factors. Early learnings from helping struggling centers improve are now being applied to train new ATCs, enabling them to avoid common mistakes. The company uses performance scorecards and a peer-to-peer support team to build momentum across the entire network.

Asked for details on COM701's activity in PD-L1 positive patients in light of Merck's B96 trial, and inquired about the potential for combining their TIGIT with a PD-1/VEGF therapy, the rationale for an Fc inactive approach in that context, and if this has been discussed with partners.

Answer

The company responded that COM701 has shown activity in both PD-L1 positive and negative patients, which they attribute to the unique PVRIG biology. Regarding PD-1/VEGF combinations, they see a mechanistic rationale for combining with PVRIG blockade. They believe an Fc inactive TIGIT would be preferable in such a combination to avoid potential additive toxicity, as combining a PD-1/VEGF with a potentially toxic Fc active TIGIT could be challenging.

Asthika Goonewardene of Truist Securities asked about the biomarker strategy for the upcoming Phase 2 study, the rationale for not including TIGIT blockade initially, and whether the company had received any feedback from the FDA on the trial design.

Answer

Chief Scientific Officer Dr. Eran Ophir explained that while an initial signal for the PVRL2 biomarker exists, the data is not yet sufficient for prospective enrichment, so the trial will rely on its design for a response signal while continuing to collect biomarker data. He stated that TIGIT blockade could be a logical next step in the platform study after COM701 monotherapy potentially increases T-cell infiltration. Chief Medical Officer Dr. Michelle Mahler confirmed they have not yet spoken with the FDA but have designed the trial to be robust and align with agency guidance, planning to engage post-data.

Asthika Goonewardene of Truist Securities asked if the rationale for using an anti-CD52 antibody, based on early Cellectis data in refractory settings, still applies to the different dynamics of the first-line consolidation setting. He also inquired if upcoming data would detail the patient mix.

Answer

CEO Dr. David Chang agreed the historical context was correct for refractory disease but stressed that the minimal disease MRD-positive setting is fundamentally different, which was a core hypothesis behind the trial's original three-arm design. He noted they would aim to provide informative data on patient mix, but the futility analysis is based on a small cohort of 24 patients.

Representing Asthika Goonewardene, Karina Rabayeva asked if the ALLO-316 program in renal cell carcinoma has been deprioritized given the focus on other assets.

Asthika Goonewardene of Truist Securities asked for details on the Phase II/III trial design for BNT327 in NSCLC, including cohort sizes and the rationale for the statistical analysis plan.

Answer

CMO Özlem Türeci and CEO Ugur Sahin clarified the trial design. The Phase II dose-justification portion involves ~40 patients, while the Phase III component will enroll over 940 patients. Sahin explained that, following FDA discussions, they are treating squamous and non-squamous histologies as two separate indications in the analysis due to recent data showing different outcomes for some therapies in these populations.

Asthika Goonewardene of Truist Securities questioned what the right comparator would be for a future pivotal trial of casdatifan plus volrustomig in RCC and asked about the importance of matching or exceeding the durable complete response rate seen with ipilimumab-nivolumab.

Answer

CMO Dimitry Nuyten identified the CheckMate-214 study (ipi-nivo) as the relevant benchmark, noting the combination's key advantage could be reducing the high primary progression rate seen with ipi-nivo. COO Jennifer Jarrett added that this potential to improve the front-end of the PFS curve is what attracted AstraZeneca to the collaboration.

Asthika Goonewardene from Truist Securities asked about the readout timing for a second cohort in the etrumadenant colorectal cancer study and inquired about the rationale for combining HIF-2 alpha inhibitors with checkpoint inhibitors.

Answer

CEO Terry Rosen explained that the readout for the second etrumadenant cohort is expected sometime in 2025, as the data is not yet mature. Regarding combinations, he affirmed that pairing a HIF-2 alpha inhibitor with anti-PD-1 or anti-CTLA4 is a logical strategy and mentioned that a second registrational trial for casdatifan in the frontline setting will be announced soon.

Asthika Goonewardene of Truist Securities asked for details on the IGM-8444 caspase-3 biomarker data, including measurement timing and patient distribution, and pressed for more specific timing on future data releases.

Answer

Chief Medical Officer Dr. Chris Takimoto clarified that the caspase-3 data represents the maximum change observed, which occurs quickly after treatment, and noted the 10 mg/kg cohort was mostly monotherapy patients while the 3 mg/kg cohort was mostly FOLFIRI combination patients. CEO Fred Schwarzer reiterated that while a data release for the single-arm cohorts in 2023 is a "reasonable hope," no firm decision has been made.

Asthika Goonewardene questioned if the interferon-gamma dominant cytokine profile of IGM-2323 holds up with repeat dosing, asked about the time elapsed since the prior CAR-T treatment for the patient who experienced CRS, and inquired about the dissociation kinetics of IGM-2323 from tumor cells.

Answer

Chief Medical Officer Daniel Chen confirmed that the repeatable interferon-gamma dominant T-cell activation remains a primary hypothesis and a key factor they are looking to optimize for the recommended Phase II dose. He noted the prior CAR-T treatment was not recent. Chief Scientific Officer Bruce Keyt added that the dissociation rate of IGM-2323 from the tumor target is effectively irreversible, leading to very durable effects, a finding consistent with clinical observations.

Asthika Goonewardene inquired about the success criteria for the upcoming HB-200 data, specifically asking about the bar for duration of response (DOR) and progression-free survival (PFS), and also asked about potential future components to add to the HB-200/PD-1 combination therapy.

Answer

Chief Medical Officer Katia Schlienger explained that while they will report on various efficacy endpoints, the duration of response data will likely be immature at the Q2 update and requires more follow-up. CEO Joern Aldag added that while PFS is short for the standard of care, their data will allow for a comparison. Regarding future combinations, Mr. Aldag pointed to the upcoming AACR data with IL-2 as an example of how they are exploring ways to enhance therapeutic effects.

Asthika Goonewardene of Truist Securities asked for more detail on the AACR presentation, specifically the number of patients with translational data, the type of analysis to be used for T-cell response, and whether any biopsy or T-cell fitness data would be included.

Answer

Igor Matushansky, Chief Medical Officer, stated the AACR data will include a single-digit number of patients, primarily from the HB-201 arm. The analysis will be a direct Elispot assay, with percentage-based data likely coming closer to ASCO. He clarified that biopsy and T-cell fitness data are planned for presentation at the SITC conference, not AACR.
