This afternoon we released financial results for the quarter ended 03/31/2025 and recent corporate updates. The press release is available on the Investors section of our website at revmed.com, along with an updated investor presentation, which we will be referencing during today's call. With that, I'll turn the call over to Doctor. Mark Goldsmith, Revolution Medicine's Chairman and Chief Executive Officer. Mark?

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Thanks, Ryan. It's good to be with you this afternoon. Today, I'll highlight some of the progress we've made this quarter against the strategic priorities we outlined earlier this year. I'll then pass the call over to Doctor. Steve Kelsey, who will walk through a strategic framework for our developing plans in non small cell lung cancer.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Doctor. Wei Lin will then highlight updated data from several of our ongoing non small cell lung cancer cohorts that provide support for our plans in lung cancer. Jack Anders will then provide a summary of our first quarter financial results before I share closing remarks and open the call to Q and A. At Revolution Medicines, we remain committed to revolutionizing treatment for patients with RAS addicted cancers through the discovery, development, and delivery of innovative targeted medicines. We continue to make important strides in pursuit of this mission as we execute, advance, and extend our understanding of our novel RasOn inhibitors.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

We believe and have increasingly been able to demonstrate that our compounds have the potential to become important therapeutic options for patients living with RAS addictive cancers. Our first three clinical stage RasOn inhibitors with highly differentiated and promising clinical profiles include doraxonrasib, a groundbreaking Rason multi selective inhibitor, elieronrasib, a distinguished G12C selective covalent inhibitor, and zoldonrasib, a highly innovative G12D selective covalent inhibitor. We continue to make substantial progress advancing these programs with a vision to maximize the clinical impact across tumor types and lines of therapy through a mix of single agent and combination strategies. Pancreatic cancer is an important priority, and our strategy involves executing on the ongoing phase three RAASILUTE-three zero two trial of diraxonrasib in patients with previously treated disease, while moving aggressively into earlier lines of therapy. We are working quickly to prepare for the initiation of two additional Phase III studies with diraxonrasib in pancreatic cancer in the second half of twenty twenty five.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

'1 of these trials will be in patients with first line metastatic disease, and is expected to compare a reference arm of patients treated with chemotherapy to two investigational arms, One with patients treated with diraxonrasib monotherapy, and one with patients treated with diraxonrasib plus chemotherapy. The other early line trial will be as adjuvant treatment for patients with resectable pancreatic cancer who have undergone surgery and perioperative therapy, typically including chemotherapy. In addition to this robust plan for draxonrasib to play an important role in the treatment of pancreatic cancer across lines of therapy, we have similar ambitions for broad development in RAS mutant non small cell lung cancer. The principal focus of today's call is to provide further color and support for our non small cell lung cancer strategy. And I'd like to invite Doctor.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Steve Kelsey to walk you through our current conceptual framework. Steve.

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

Thanks, Mark. Improving treatment options for patients with RAS mutant lung cancer is an important priority for revolution medicines. The majority of patients with non small cell lung cancer are either diagnosed with or later develop metastatic disease treatment objectives for these patients include symptom improvement by reducing tumor burden, delaying disease progression, prolonging survival and improving quality of life. Thirty percent of patients with non small cell lung cancer harbor a RAS mutation. There are still no full regulatory approvals for RAS inhibitors in any RAS mutant lung cancer.

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

Nevertheless, due to the commercial availability of KRAS G12C off inhibitors by accelerated and conditional approval mechanisms, RAS mutant non small cell lung cancer has effectively evolved into two diseases and treatment paradigms. GTOC mutant disease, which represents around twelve percent of non small cell lung cancer and other RAS mutant non small cell lung cancer, which we are referring to as non G12C RAS mutant non small cell lung cancer. The second group accounts for around eighteen percent of non small cell lung cancer. We expect segmentation of the RAS mutant non small cell lung cancer space to continue into mutational groups as other mutant selective inhibitors advanced through clinical development and receive regulatory approvals. Our aim at revolution medicines is to establish our portfolio of Ras on inhibitors as the leading therapies for patients with Ras mutant on small cell lung cancer across all Ras mutations and lines of therapy.

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

We strive to develop first and or best in class RAS inhibitors and combinations. Our strategy for metastatic disease depends on a number of variables. First, which rash mutation, the tumor harbors and whether a mutant selective RAS inhibitor has achieved proof of concept. Second, the line of therapy for metastatic disease as the expectations and standards of care are different between initial therapy and salvage therapy. Diracs on Rasib has shown encouraging antitumor activity in patients with tumors harboring a wide range of RAS mutations.

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

Nonetheless, in the face of RAS addiction by such tumors, we expect that mutant selective inhibitors should also have a role in treating tumors with corresponding RAS driver mutations. Combining these mutant selective inhibitors with a RasR multi selective inhibitor may play an important role by delivering deeper target inhibition and overcoming resistance mechanisms in a way that neither approach can achieve on its own. Our previously published data show that the rax on rats, it is active against a broad range of rash mutations that have been frequently identified as mechanisms of escape from mutant selective KRAS inhibitors consistent with this. And as we recently presented at AACR, new RAS point mutations are an infrequent cause of escape from diracs onrasib in pancreatic cancer. A rash on inhibitor, doublet combination has the goal of improving outcomes and potentially providing a chemotherapy sparing option for patients with mass mutant non small cell lung cancer.

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

In the previously treated metastatic setting use of a single agent RAS inhibitor may be sufficient to improve outcomes over the current chemotherapy standard of care. This is the approach we're taking with doraxonrasib in patients with previously treated RAS mutant non small cell lung cancer in the RESOLVE three zero one study. For first line treatment of metastatic disease, the dominant standard of care includes immune checkpoint inhibitors, primarily pembrolizumab. Demonstrating safety and tolerability with pembrolizumab is critical as a means of enabling first line therapy and maximizing the durability of any clinical benefit. These concepts have currently been reduced to practice by revolution medicines.

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

Single agent Diracsom RASID provides a foundation for the investigation of Ras on inhibitors in all Ras mutant non small cell lung cancer in the second line and beyond setting. As recently presented at AACR Zolgensma Rasid has encouraging activity as a single agent in second line plus Rats G12D mutant non small cell lung cancer. In the first line, RAS G12C non small cell lung cancer setting, we aspire to develop chemotherapy sparing Ras on inhibitor doublet of directs on Rasid plus a layer on Rasid with pembrolizumab and thereby reserve platinum based chemotherapy for second line treatment doing so has the potential to contribute to an improvement in overall survival. In first line, Ras non G12C non small cell lung cancer, we plan to develop doraxonerasib in combination standard of care. Eventually, Zolgensma Rasib with its encouraging monotherapy profile may offer a path to another chemotherapy sparing Ras on inhibitor doublet for patients with Ras G12D tumors and similar doublet approaches may be possible with other Ras mutant selective inhibitors, such as RMC5127 targeting RAS G12V.

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

I will now turn the call over to Doctor. Wei Lin to provide an update across our non small cell lung cancer clinical programs. Wei.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

Thank you, Steve. I'll start by providing monotherapy updates across our portfolio. Beginning with duraxone rasib, our most advanced RAS on inhibitor. This multi selective inhibitor has demonstrated compelling results across multiple tumors, including lung cancer, and is currently being evaluated in a Phase three registrational study for patients with previously treated non small cell lung cancer. We're currently activating study sites for RESOLVE-three zero one.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

The study randomized approximately four twenty patients to either grasminrasib monotherapy or docetaxel. These patients must have received either one or two prior lines of therapy, including immunotherapy and platinum based chemotherapy, given either concurrently or sequentially. RESOLVE-three zero one incorporates a nested design, with the primary analysis being performed in the core population of non small cell lung cancer patients with RAS G12X mutations, excluding G12C. The extended population will incorporate all patients with RAS mutant non small cell lung cancer, including those with tumors harboring G12C, G13, or Q61 mutations. The study has dual primary endpoints of progression free survival and overall survival.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

Moving to G12B non small cell lung cancer. We've previously shown promising activity by thoraxone rasip in patients with these tumors, and the ongoing RESOLUTE-three zero one recreational study includes such patients. Last month, at AACR, initial clinical results were presented for sildonrasib, our Ras on G12D selective covalent inhibitor from the non small cell lung cancer cohort. I'll walk you through these data. Nodonatinib was well tolerated with manageable and predominantly low grade treatment related adverse events, as shown on the safety table.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

As of the 12/02/2024 data cutoff, at the 1,200, two grade three adverse events were reported among ninety patients with only two dose interruptions and no dose reductions. Zolranasib achieved a favorable mean dose intensity of 98%. Zodonaracib monotherapy at the twelve hundred milligram daily dose demonstrated encouraging anti tumor activity. The waterfall plot shows the best percentage change in tumor size for patients with non small cell lung cancer who received their first dose of zolonrasib at least eight weeks prior to the data cutoff date. The objective response rate was sixty one percent, including patients with a confirmed response or a response that was pending confirmation.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

The disease control rate was eighty nine percent. We'll continue following these patients to define durability. Now I'll move to our RasOn G12C mutant selective covalent inhibitor, gileron rasib, in non small cell lung cancer. We reported the first clinical data on evelonracep in non small cell lung cancer at the triple meeting in 2023. And today, I'll share updated elanorazib monotherapy data that includes more patients and longer follow-up as a foundation for combination strategies to move into first line metastatic and eventually earlier lines of non small cell lung cancer.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

As of the 04/07/2025 data cut off, thirty six patients who had received prior treatment with standard care were treated with veironrasib monotherapy at two hundred milligrams twice daily. The veironrasib was generally well tolerated with treatment related adverse events consistent with previously reported data. The most frequently observed treatment related adverse events were gastrointestinal and asymptomatic QPC prolongation. Galeron Rasib achieved a favorable mean dose intensity of ninety four percent. There we show the clinical activity in the same thirty six patients treated with varenrapid monotherapy, and the dose of two hundred milligram twice daily.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

The objective response rate in these patients was fifty six percent, The disease control rate was ninety four percent. The estimated median progression free survival in these patients was nine point nine months. I'll now cover our combination clinical development to enable our goal of improving treatment outcomes for patients with RAS mutant non small cell lung cancer in the first line metastatic setting. The need for improved treatment options for patients with metastatic non small cell lung cancer remains high. In the first line setting, two regimens are widely used globally.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

Pembrolizumab plus chemotherapy is the most commonly used treatment for all patients regardless of their tumor PD L1 expression status as measured by tumor proportion score or TPS. And pembrolizumab monotherapy is the preferred regimen in patients with TPS greater than or equal to fifty percent, which accounts for about one third of patients with non small cell lung cancer. While the introduction of immunotherapy has been transformative for patients with non small cell lung cancer, especially those with high PD L1 expression, but the data in these table indicate non small cell lung cancer remains a disease with high unmet need. Because among the approximately two thirds of patients who have tumors with lower or no PD L1 expression, even the best available standard of care has not resulted in reported response rates above forty percent. In RAF mutant non small cell lung cancer in the second line and beyond, treatment is generally either the chemotherapy docetaxel or a KRAS G12C OP inhibitor.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

As illustrated in the table, reported response rates for docetaxel have been less than fifteen percent, Even with the commercially available KRAS G12C off inhibitors of sotorasib and adagasib, reported patient outcomes have been modest with response rates of approximately thirty percent. Combinations are likely to remain a foundation of first line metastatic treatment for non small cell lung cancer. And our main objective is to determine the best way to bring targeted RAS inhibitors into combination with immunotherapy for the first line treatment of RAS mutant non small cell lung cancer. These figures from preclinical experiments illustrate two concepts that guide our clinical approaches. The first concept shown on the left is that two RAS inhibitors can be combined to increase antitumor activity.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

In this experiment with KRAS G12C non small cell lung cancer model, either eleroniracib or daratumumab alone significantly increased progression free survival compared to control, as measured by time to tumor doubling. Notably, the combination of eleroniracib plus diruxaniracib prolonged progression free survival even further, indicating additive durability from the RasOn inhibitor doublet. The second concept shown in experiment on the right is that this RasOn inhibitor doublet significantly synergizes with immunotherapy. In this experiment, we used an immune refractory KRAS C12C non small cell lung cancer tumor that was unresponsive to anti PD-one inhibitor alone, and only partially responsive to anti PD-one combined with either RasOn inhibitor. Essentially, no progression was seen in this model during one hundred days of treatment with anti PD-one combined with a Rasgon inhibitor doublet.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

Encouraged by preclinical results of this sort, I will now describe new clinical data from our evaluation of pairwise combinations of doraxone rasib plus pembrolizumab, eleron rasib plus pembrolizumab, and eleron rasib plus doraxone rasib that suggest these concepts may translate in patients with KRAS C cross C non small cell lung cancer. The first combination dataset I'll review is daratumumab plus templizumab with or without chemotherapy. Dirasanirasib plus pembrolizumab with or without chemotherapy has been generally well tolerated in patients with non small cell lung cancer. Previously, we showed acceptable tolerability for the combination of doroxonracib with pembrolizumab in later line patients. And with further follow-up, the tolerability profile in those patients has remained stable.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

Today, we're focusing on patients with first line disease. While the follow-up is shorter for patients in the first line setting, the tolerability profile of daratumumab plus pembrolizumab is consistent with what has been observed in the second line setting, with or without the addition of chemotherapy. No new safety signals were seen, and the overall tolerability profile is consistent with that of duraxialerase plus standard of care agents. Rash, gastrointestinal toxicities, and stomatitis mucositis remain the most commonly observed adverse events for doroxonrasib, and neutropenia and thrombocytopenia emerged with addition of chemotherapy. The tolerability profile supports the further development of daratumumab plus pembrolizumab with or without chemotherapy.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

Dose reductions and discontinuation of daratumumab or pembrolizumab in this combination were modest. Ziruchanratib achieved a favorable mean dose intensity of ninety three percent in combination with pembrolizumab, and ninety percent with additional chemotherapy. While only a limited number of first line patients have had sufficient follow-up to have had a tumor assessment. We're encouraged by the antitumor activity seen to date. In the left figure, patients had tumors with TPS greater than or equal to 50%, and were treated with diraxone rasit plus pembrolizumab, consistent with a population who would have received pembrolizumab monotherapy as standard of care.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

Of the seven efficacy valuable patients who had undergone at least one tumor assessment, 80 six percent of these TPS greater than or equal to fifty percent patients had a RECIST response, and all had achieved disease control and remained on treatment. While the data set will continue to evolve with addition of more patients and longer follow-up, this is a very encouraging start. In the figure on the right, patients with TPS less than fifty percent were treated with daratumumab plus pembrolizumab and chemotherapy, consistent with the roughly two third of first line patients who would likely receive pembrolizumab plus chemotherapy as standard of care. Of the ten efficacy valuable patients who had undergone at least one scan, 50 percent of these TPS less than fifty percent patients had a RECIST response, and ninety percent achieved disease control. These data support the continued development of doroxoniracib plus standard of care in first line RAS mutant non small cell lung cancer.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

I'll now touch on avaranracid plus pembrolizumab combination. Demonstrating the safety of this combination is important as we take a pairwise approach toward our goal of developing a chemotherapy sparing triplet combination of bevariance, duroxanracid, and pembrolizumab in patients with first line metastatic KRAS C12C non small cell lung cancer. We previously showed acceptable tolerability for the leonaracib plus pembrolizumab combination in the second line plus setting. With further follow-up of these of those patients, we have not observed an increase in additive toxicity. Today, we'll focus on initial results in patients with first line non small cell lung cancer.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

As of the 02/10/2025 data cutoff, the combination of veverimeracib with pembrolizumab showed a well tolerated profile with few grade three or higher treatment related adverse events. No new safety signals were observed. This tolerability profile translated to an acceptable dose modification rate in either the second line or first line setting. And eleroniracib maintained a favorable mean dose intensity of eighty five percent. The combination of eleroniracid with pembrolizumab showed encouraging preliminary anti tumor activity.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

Among five efficacy valuable patients with first line non small cell lung cancer, and a TPS greater than or equal to fifty percent, all achieved a RECIST response. Our development strategy in the first line, RAS G12C mutant non small cell lung cancer is to replace the standard care with the triplet regimen of valerulatinib, doroxoniracib, and pembrolizumab as a chemo sparing regimen. I've just shown data supporting the combinability and anti tumor activity of doroxoniracib plus pembrolizumab and evereniracib plus pembrolizumab. The third peer wise combination needed to support this triplet regimen is the Rasong inhibitor doublet of everonRasib plus dirasongRasib. This Rasong inhibitor doublet concept is supported by strong results in preclinical models, including models that are refractory to monotherapy approaches.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

In these preclinical models, deep and durable responses are seen in RAS on inhibitor doublets. In December 2024, we shared initial clinical data for the RADS1 inhibitor doublet of eleroniracid plus duraxaniracid to establish the mechanistic proof of principle for this combination. We evaluated a challenging population of colorectal cancer patients who had been previously treated with not only standard care chemotherapy, but also with KRAS C12C off inhibitors and anti EGFR antibodies. These early results demonstrated an acceptable tolerability profile, along with encouraging anti tumor activity in a very difficult to treat patient population. These results provided strong rationale for continued development of this RasOn inhibitor doublet approach across tumor types and lines of therapy.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

Today, I'll share initial dose finding data from this RADS1 inhibitor doublet in patients with non small cell lung cancer. The data in this table demonstrate the combinability of valeroniracid with doroxoniracid, with a tolerability profile that is largely consistent with that of doroxoniracid itself. Even with longer follow-up, hepatotoxicity did not emerge as a safety signal in this larger cohort of lung cancer patients. QT prolongation ECG was not symptomatic, and is not common with a grade three rate of only three percent. This tolerability profile translated to no treatment discontinuations, and a favorable mean dose intensity of ninety five percent for the valroxenracib and eighty five percent for duroxanracib.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

The combination of the valroxenracib plus duroxanracib showed encouraging preliminary anti tumor activity in twenty six patients with previously treated KRAS C12C non small cell lung cancer, who had been previously treated with a KRAS C12C off inhibitor. Because dose optimization of the RASP on inhibitor doublet is ongoing, we're sharing doraxoneuracid at doses ranging from one hundred milligrams to two hundred milligrams. On the left, we're showing the laramiracet monotherapy data in patients who were previously treated with a KRAS T12C off inhibitor. The response rate and disease control rate for laramiracet monotherapy were forty two percent and seventy nine percent respectively. On the right, for the combination of valeroniracid and doroxaniracid, the response rate was sixty two percent, and the disease control rate was ninety two percent, well above the activity seen in this population with veronaracid monotherapy.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

The majority of patients on the combination remained on treatment as of the 02/10/2025 data cut off date. Taking a step back and looking at our data driven lung cancer strategy, we believe we have a clear path to pursuing our ambition to change the standard of care for patients with RAS mutant lung cancer, both in first line metastatic and in earlier lines of treatment. We launched our initiative in non small cell lung cancer with our registrational study for dirazepamirazepammonotherapy in previously treated patients with RAS mutant lung cancer. The emerging zodonRASSID data point to clear opportunities to continue evaluating zodonRASS in patients with RAS G12D mutant non small cell lung cancer as monotherapy and in combination. The three pairwise combinations of duraxaneracib plus pembrolizumab, belaraneracib plus pembrolizumab, and the Rasa inhibitor doublet of belaraneracib plus duraxaneracib, all show acceptable tolerability and encouraging antitumor activity, and create options in the first line treatment setting.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

For patients with tumors harboring RAS G12C, we plan to pursue a chemo therapy sparing Rasam inhibitor doublet treatment, including leroniracid plus doroxoniracid along with checkpoint inhibitor. For patients with non G12C disease, we plan to develop diraxameracid in combination with standard care chemotherapy, along with checkpoint inhibitor. We believe each compound in our clinical stage RAS inhibitor portfolio has the potential to transform treatment for patients living with RAB mutant non small cell lung cancer. With that, I'll turn the call over to Jack.

Jack Anders
Jack Anders
Chief Financial Officer at Revolution Medicines

Thanks, Wei. We ended the first quarter of twenty twenty five with $2,100,000,000 in cash and investments, which we project can fund planned operations into the second half of twenty twenty seven based on our current operating plan. R and D expenses for the first quarter of twenty twenty five were $205,700,000 compared to $118,000,000 for the first quarter of twenty twenty four. The increase in R and D expenses was primarily due to increases in clinical trial related expenses and manufacturing expenses for our three clinical stage programs, with doraxoneurasib being the largest driver of the increase given the program is now in two Phase III trials. Personnel related expenses and stock based compensation expense also increased in 2025 due to additional headcount.

Jack Anders
Jack Anders
Chief Financial Officer at Revolution Medicines

G and A expenses for the first quarter of twenty twenty five were $35,000,000 compared to $22,800,000 for the first quarter of twenty twenty four. The increase in G and A expenses was primarily due to increases in personnel related expenses and stock based compensation associated with additional headcount and commercial preparation activities. Net loss for the first quarter of twenty twenty five was $213,400,000 compared to $116,000,000 for the first quarter of twenty twenty four. The increase in net loss was due to higher operating expenses. We are reiterating our 2025 financial guidance and continue to expect projected full year 2025 GAAP net loss to be between $840,000,000 and $900,000,000 which includes estimated noncash stock based compensation expense of between $115,000,000 and $130,000,000 That concludes the financial update.

Jack Anders
Jack Anders
Chief Financial Officer at Revolution Medicines

I'll now turn the call back over to Mark.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Thank you, Jack. We are making meaningful progress as we successfully execute on our twenty twenty five strategic priorities in pursuit of our goal to revolutionize treatment for patients with RAS addictive cancers. A key focus this year is executing on the diraxoneRASB registrational studies in both previously treated pancreatic and non small cell lung cancers. I'm pleased to share that RASLUT-three zero two, our ongoing global Phase III trial in patients with second line metastatic pancreatic cancer, continues its strong pace of enrollment in The US. Following regulatory clearances in The EU and Japan, we've also begun enrolling patients in those geographies.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

We are confident that we'll be able to substantially complete enrollment this year to enable an expected data readout in 2026. We are also currently activating study sites for RESOLVE-three zero one, our Phase three trial in patients with previously treated RAS mutant non small cell lung cancer. We're making good progress toward advancing daraxonrasib into earlier line, randomized pivotal trials, with planning underway to initiate registrational trials for daraxonrasib in first line and adjuvant pancreatic cancer in the second half of this year. Today, we've shared important data that create exciting opportunities for us, in both previously treated and first line metastatic non small cell lung cancer, and eventually earlier lines of treatment, including treatment approaches that include our mutant selective inhibitors. We continue to expand our clinical programs and follow study patients to enable the initiation of one or more pivotal combination trials in 2026.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Progressing our earlier stage pipeline, including advancing next generation innovations, continues to be an important priority. At AACR recently, RMC-five thousand one twenty seven, our G12V mutant selective RasOn inhibitor, was presented in the New Drugs on the Horizon session. We continue to advance the program and expect to reach a clinic ready stage later this year to enable the initiation of a Phase I study next year. Finally, we continue to make substantial progress growing our commercial and operational capabilities and in advancing launch readiness activities in support of our first potential product launch. We are making good progress in building our commercialization capabilities in The United States across functions, including onboarding our US field medical team.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

We also recognize our important responsibility for ensuring patient access to doraxonerasib globally pending regulatory approvals. I'm very pleased to announce that Anthony Mancini has joined RevMed as our Chief Global Commercialization Officer and member of our senior management team. Anthony, who will oversee the comprehensive commercialization strategy and operations for our portfolio, brings substantial experience from his successful decades long career in the biotech and biopharmaceutical industry, having led significant product portfolios, launches and organizational builds in The US and major international markets, as well as overseeing significant strategic partnerships. He will contribute additional strength, both to our approach to The US market and to our evaluation of options for reaching patients internationally. Our vision remains to create the industry leading targeted medicine franchise for patients with RAS addicted cancers.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

This vision is built on three foundational pillars. First, our pioneering clinical stage RAS on inhibitors have shown our discovery capabilities to be among the most innovative and productive in the industry. Second, our first class development capabilities have been demonstrated by efficiently progressing multiple assets through first in human studies and advancing into late stage development. Third, we are building high quality organizational capabilities to ensure we can successfully deliver products to patients. Underlying all of this is an exceptionally strong financial position that gives us the wherewithal to continue executing on our strategy and solidifying our position as leaders in the treatment of patients with RAS addictive cancers.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

As we continue to deliver compelling clinical observations and build on our track record of execution, we never lose sight of our primary focus, patients living with cancer. Before we open the call for the Q and A session, I'd like to thank the patients and caregivers, clinical investigators, scientific and business collaborators, advisors, and shareholders for their commitment. Without this support, none of the progress we've made would be possible. I'd also like to recognize the extraordinary efforts of RevMed employees who embody tireless commitment to patients in the work they do every day. This concludes our prepared remarks for today.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

And I'll now turn the call over to the operator for the Q and A session.

Operator

Thank you. At this time, we will conduct the question and answer session. As a reminder, to ask a question, you will need to press 11 on your telephone and wait for your name to be announced. In the interest of time, we will allow one question per participant. If you have further questions, you may rejoin the queue.

Operator

Our first question comes from the line of Michael Schmidt of Guggenheim. Your line is now open.

Michael Schmidt
Senior Managing Director & Equity Research Analyst - Biotechnology at Guggenheim Securities, LLC

Hi, thanks for taking my questions, and congrats on all the progress. A lot of new information here to digest today. But, yeah, I had a question on your first line non small cell lung cancer strategy. Obviously, very interesting new data disclosed today for some of the various doublets. And based on your slide, it seems like for the KRAS G12C first line patient population, you're sort of focusing in on a triplet of Iliron, Racib, Daraxan, and Pembro is probably the only combination where we haven't seen data yet today.

Michael Schmidt
Senior Managing Director & Equity Research Analyst - Biotechnology at Guggenheim Securities, LLC

But just looking at some of the other doublets, maybe perhaps could you just comment on your confidence and tolerability of that triplet just based on some of the rash rates that were seeing in some of doublets and some of the dose reductions there?

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Hi, Michael. Thanks for your question. Maybe Wei can speak to that.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

Thanks for the question. So, we're optimistic given the profile we've seen so far. Obviously, we're still in the dose optimization, and we have not yet defined the final dose for the triple combination. But I think we have characterized the monotherapy fairly well. We've not seen any new safety signals emerging.

And regarding safety signals that are known characterized, such as rash regarding blacks on massive, as well as the QGC, both are within what we have expected to observe with the monotherapy. So I think when we have longer follow-up and defined the dose, we'll be sharing those prior to initiating our Phase III trial.

Thank you. Our next question comes from Mark Fram of TD Cowen. Your line is now open.

Biotechnology Equity Research Analyst at Cowen

Hi, thanks for taking my questions, and congrats on all the data sets today. Maybe just looking across the various combination data sets you presented, I was struck by I mean, looks like the vast majority of the responders are still ongoing as of the last data cutoff. Again, PFS is clearly immature, but maybe can you give us a sense of just kind of the average follow-up in those cohorts to maybe give a sense of where durability and PFS may be headed? And then kind of looking longer term, what type of data set do you think you need to gather before you can kind of formally declare Phase III intent for these various combinations? Do you just need to get a little bit more data, get more comfortable on safety and select the final dose?

Marc Frahm
Marc Frahm
Biotechnology Equity Research Analyst at Cowen

Or is it you need real robust PFS estimates? Just kind of what's needed there.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Hey, Mark, thanks for your question. I think the first question really is something that refers back to the swimmer plots that we provided in December, and I think those are available, so I'd recommend just taking a look at those in terms of follow-up time for those. We don't have an update today on that because we haven't done a fresh data cut, but the December data had those duration of treatment parameters listed. Your second question your main question, I think, is about what's really gating now to the triplet. Steve, you want to comment on that?

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

Yes. I mean, let's be clear that there's a differentiation here between the G12C program and the non G12C program. The non G12C program is pretty much ungated. It's more of a sort of operational execution type question. I think we've shown very conclusively that adding diraxone rasib to the KEYNOTE-one hundred eighty nine schedule is tolerated and the efficacy is pretty impressive.

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

So we don't think we need any more data to press ahead with that. We just have to grind through the operational and regulatory milestones that you have to go through in order to get a study off the ground. As Wei alluded to in his prepared remarks, the G12C program is currently gated by optimizing the dose of that RasOn doublet, the combination of diraxonrasib and olironrasib. Have to because it's a novel, novel combination and it's going into patients who have never received treatment for their non small cell lung cancer. We really have to get the dose right, to get the dose right to the satisfaction of the company, but also to the satisfaction of the regulators and the payers and the prescribers.

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

So a little bit more refinement is needed there. We're pretty close. We have a range within which we're operating. And I don't think it'll take too long, but that's essentially what's gating the G12C first line on small cell lung cancer program.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

A subpart of that was, is PFS required? Are we waiting for PFS? And I think that's a simple answer that PFS is really not driving that decision. We understand PFS based on the second line data, and now we have confidence that the response rates are very competitive. So I think we're good to go from that perspective.

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

Yeah, we should say, we should add that both from the published literature and historical data and from our own very pretty intense in house analysis, response rate is a reasonable correlate of PFS in non small cell lung cancer. That has not been the case for pancreatic cancer, but for lung cancer it is. So we're more confident about the link between our response rates that we've just disclosed in the lung cancer patients and predicted PFS that we will achieve. And of course, PFS in lung cancer, more compelling as a regulatory endpoint, unlike in pancreatic cancer, where we have to overall survival. So, lung cancer has got a lot more going for it.

Thank you. Our next question comes from Eric Joseph of JPMorgan. Your line is now open.

Eric Joseph
Eric Joseph
Equity Research Analyst at JP Morgan

Thanks for taking the questions, and let me also just concur. Lots of data updates here and a lot to digest. Maybe, Steve, I could get you to expand a little bit on your last comment, the types of datasets, publications perhaps that grant you confidence that rate, higher response rates would be a predictor for better PFS outcomes sort of outside of your own pipeline work. I'm also curious to know whether you are continuing to enroll the frontline lung cancer cohorts to sort of build upon the data set that you are observing so far? And then finally on the safety side, I know this is more than one question, on the safety side, nonclinical, this subclinical QT signal that you're seeing with the ferrite combination, you're confident that it won't, you know, become something greater with the triplet regimen?

Eric Joseph

I think the first part was a question

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

thank you, Eric. I think the first part was a

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

question about the literature reflecting predictive utility of response rate for durability. I think we can provide some references offline. By the way, it's something we've heard from investors for the last several years, why don't we use response rates more? So I think it's pretty generally well known, and our observations are very consistent with that. Do you have anything you want to add to that, Anel?

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

What was the second part?

Executive

Safety in the QT signal. Safety in the QT safety? A safety question about the QT signal. Concerns that it would

be greater than the treatment.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Do you

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

want to comment on that?

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

Yeah, we have not seen that to be the case. Certainly, we've reported the QTc signal. It's here. It's actually on par even lower than what we observed with monotherapy. Obviously, with longer follow-up and larger patient sample, we do not expect there's going to be an enhancement of QT.

Wei Lin
Wei Lin
Chief Medical Officer at Revolution Medicines

So I think QT is well within line of what Osimertinib has reported in their label. So I don't think it will

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

be And consistent with the larger ELIORON and longer follow-up ELIORON RACID data set that we showed at the beginning here, which I think makes that point pretty clear.

Eric Joseph

Thank you. Our next question comes from Jonathan Chang of Leerink Partners. Your line is now open.

Jonathan Chang
Senior Managing Director at Leerink Partners

Hi guys, thanks for taking my question. How are you thinking about the duration of clinical benefit of DuraXonRafib versus the mutant selective inhibitors like Zolgensma and ElironRafib? What are the reasons for why one could be more durable than the other, and how could this and other factors impact how you're thinking about future development strategies? Thank you.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Thanks, Jonathan. Maybe I'll comment on that, and then if Steve or Wei wants to add anything to it. I don't think we have any direct head to head comparison, because the diraxone Rasib study was done in tumors that carry different mutations than the OLERO ON RACF study, so we really can't compare those, so we can't say which is superior to the other, and they're not matched for other prognostic factors as well. So I don't think we have any information on it. You know, if you're wondering what we might predict, I don't know.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

We'll see. And ultimately, we're combining these anyway, as both Wayne and Steve have talked about, and so one ought to get the benefit of whatever the pros are on each side of that. Is there anything more specific that you're trying to get at there?

Jonathan Chang
Senior Managing Director at Leerink Partners

I was just thinking about how in situations where you might be considering advancing the multi RAS or a mutant selective one, or maybe the combination of both, how you might consider things like duration of clinical benefit and how long patients may stay on treatment in addition to other considerations?

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

It's the number one consideration, because that's the key driver of the patient experience, assuming that we obviously have a combination that patients can tolerate for the time that they're on the treatment without having a miserable life, it's the number one consideration. Mechanisms of escape from the mutant selective inhibitors are very different from the mechanisms of escape from doraxonerasib. We have only disclosed mechanism of escape data for doraxonerasib in pancreatic cancer, but it's a very different pattern of escape from what's being disclosed for mutant selective inhibitors in non small cell lung cancer. And that's why we're so enthusiastic about the combination, because all of those putative mechanisms of escape are covered by the combination. The novel RAS mutations that emerge on the mutant selective inhibitors are inhibited by diraxone rasib, and the putative amplification of mutant KRAS that we might see in lung cancer, which we have seen in pancreatic cancer, is suppressed by hitting the mutant harder with the combination of the two RAAS on inhibitors together.

Steve Kelsey
Steve Kelsey
President of Research & Development at Revolution Medicines

So we do expect the PFS to be longer with the combo than with either agent alone. And that as we described, the increase in response rate is a good harbinger of that. We just have to wait for that data to mature in order for it to be worthwhile disclosing publicly, because immature PFS data isn't helpful to anybody.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Yeah. And Steve's comments are entirely consistent with what we have reported in the preclinical context, and I think Wei showed two figures representative of a much larger data set that we presented over several scientific meetings, that the combination does tend to deliver significantly greater benefit, and including the figure on the right side of that slide I'm not sure what it is in your deck but that right figure shows the combination of the doublet plus anti PD-one, and it basically provided for no progression in any of the animals in that experiment across one hundred days. So I think the totality of the evidence is supportive of what Steve suggested.

Jonathan Chang
Senior Managing Director at Leerink Partners

Got it. Thanks for taking the question.

Thank you. Our next question comes from Kelly Hsieh of Jefferies. Your line is now open.

Clara Dong
Clara Dong
Vice President - Biotechnology Equity Research at Jefferies

Hi, this is Clara on for Kelly. Thanks for taking our question. Congrats on the data. So for non small cell lung cancer with all the combination updates and it seems like you have really multiple paths to pursue the opportunity in lung and you also have total pancreatic development as well as maybe other early initiatives such as G12V. So maybe from a resource allocation perspective, what are the key criteria driving priorities between all those developments?

Clara Dong
Clara Dong
Vice President - Biotechnology Equity Research at Jefferies

And also for lung cancer specifically, how should we think about cadence of initiating pivotal combination trials? And you mentioned you might initiate combination trials in 2026. Thank you.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Okay. Thank you, Clara. Let me start with the second comment about timing. I mean, have provided some timing, and I think that's all we can provide today. We do have, of course, Draxon Rastiv in non small cell lung cancer already underway in the 03/2001 study, but then in terms of first line and combination studies, we'd expect to begin rolling those out in 2026.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

In terms of resource allocation, I don't think there's a simple single word or sentence answer to help clarify that for you. It's obviously a pretty complex and rich set of opportunities. It's sort of an embarrassment of riches that each clinical study we've done so far opens up pretty exciting new pivotal trials that we could consider doing. So it certainly does create some need for prioritization. We start with the clinical data, the biological rationale behind the data, we look at the competitive landscape.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

As Steve pointed out, ultimately what's most important is to provide durable clinical benefit. So that's a key characteristic that gets ranked in all of this. So many, many factors. And at this point, we're able to proceed with a large chunk of the priorities that we have defined. We're basically moving everything forward right now that is ready to be moved forward in 2025, and we'll continue to do that into 2026, constantly looking at justification for the investments, but also trying to achieve the goal that we've alluded to several times here, which is to deliver significant changes on behalf of patients across RAS mutations, tumor types, and lines of therapy, and we think we're best positioned in the industry to do that.

Thank you. Our next question is from Ellie Merle of UBS. Your line is now open.

Hey, guys. Thanks for taking the question, and congrats on all the progress. Just curious your latest thinking on a potential commercial strategy ex U. S. And your general philosophy around potential partnering.

Eliana Merle
Eliana Merle
Analyst at UBS Group

And then just in terms of the designs for the pivotal combination trial or trials, could you give us maybe any more color on when you might expect to meet with the FDA to discuss the designs, and when we might be able to learn more about the specifics of the designs from our end? Thanks.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

Hi, Ellie. Thanks for your question. On the second point, unfortunately, no, we don't typically sort of lay out the timeline for our future interactions or ongoing interactions with the FDA. Our pattern that we've tried to establish is once we definitize a plan, or are close to a definitive plan, we often provide some sort of update, including the data to support whatever commitment we're making. But beyond that, I can't give you any further higher resolution answer to it.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

With regard to the ex US strategy, that's obviously very much on our minds, as I think it is on our investors. Since I first raised almost two years ago now, the possibility that we might engage with others to help us commercialize outside The US, while we would certainly focus on retaining The US market. We have had strong interest from multiple global pharma companies. We've had concrete and productive dialogue with them. And without a doubt, we could enter an attractive partnership, and that really creates a great deal of optionality for us.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

We've also felt no need to rush into such a partnership, and we've continued to use time to our advantage. We've continued tracking the portfolio, tracking the assets, progress trajectory. We've also tracked organizational progress and trajectory, and all of those have continued to exceed our expectations. So now we're in the position to assess the pros and cons of all the options that are available to us. And we have to make a strategic judgment, which we're just not ready to make today, which is what's the best approach for serving patients not only in The U.

Mark Goldsmith
Mark Goldsmith
CEO, President & Chairman at Revolution Medicines

S. But also internationally, and that also serves our business. And we are continuing to look at that, but now through the lens of where we are in 2025, with a very different organization in terms of depth and breadth, programs, maturity programs, and also with the addition now of Anthony, who joins the team and can bring a very broad commercial perspective to it as well. So we will complete that analysis at some point and continue to provide updates as appropriate.
