RMC-6291

First clinical results for RMC-9805, a RAS(ON) G12D-selective inhibitor, demonstrate encouraging tolerability and antitumor activity in patients with PDAC Investor webcast to be held Friday, October 25 at 12:00 p.m. Eastern Time (ET) Oct. 25, 2024 -- Revolution Medicines, Inc. (Nasdaq: RVMD), a clinical-stage oncology company developing targeted therapies for RAS-addicted cancers, today announced preliminary safety and antitumor data for RMC-9805, its RAS(ON) G12D-selective inhibitor, in patients with previously treated pancreatic ductal adenocarcinoma (PDAC). These initial results were presented during the late-breaking oral session at the EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Barcelona on October 25, 2024. “We are pleased to report the first clinical data for RMC-9805, our novel, oral RAS(ON) G12D-selective covalent inhibitor, which demonstrate encouraging initial safety, tolerability and antitumor activity evidenced by tumor regressions,” said Mark A. Goldsmith, M.D., Ph.D., chief executive officer and chairman of Revolution Medicines. “While preliminary, these data bolster our belief that RMC-9805 has the potential to play a role in an emerging treatment paradigm for patients living with pancreatic cancer, both as monotherapy and in combinations. With today’s presentation, RMC-9805 becomes the third tri-complex compound from the Revolution Medicines pipeline to demonstrate clinical proof-of-concept, and it reaffirms our commitment to bringing novel RAS(ON) inhibitors to patients with RAS-addicted cancers.” The RMC-9805-001 Phase 1/1b study is a multicenter, open-label, dose-escalation and dose-expansion study designed to evaluate RMC-9805 in patients with advanced solid tumors harboring a KRAS G12D mutation. As of the September 2, 2024 data cutoff date, 179 patients were treated with escalating doses of RMC-9805 (ranging from 150-1200 mg once daily (QD) and 300-600 mg twice daily (BID)). Study patients had received a median of two prior therapies (range 0-9) and all had previously been treated with standard of care. As of the data cutoff date, RMC-9805 demonstrated an encouraging safety profile and was generally well tolerated across dose levels. For patients receiving 1200 mg of RMC-9805 daily (n = 99), the most common treatment-related adverse events (TRAEs) occurring in greater than 10% of patients were GI-related toxicities (nausea, diarrhea and vomiting) and rash that were primarily Grade 1 in severity and typically of limited duration. One Grade 3 TRAE of ALT elevation was reported, and no Grade 4 or 5 TRAEs were observed. Four patients (4%) experienced TRAEs that led to dose reduction and no patients discontinued treatment as a result of TRAEs. No dose limiting toxicities were observed and the maximum tolerated dose was not reached. Preliminary efficacy was assessed in PDAC patients. At a candidate recommended Phase 2 dose of 1200 mg daily (20 patients at 1200 mg QD and 20 patients at 600 mg BID), patients who received a first dose of RMC-9805 at least 14 weeks prior to the data cutoff date achieved a 30% (n = 12) objective response rate (confirmed or pending), with a disease control rate of 80% (n = 32). “Pancreatic cancer is the most RAS-addicted of all major cancers and the G12D variant is the most common RAS mutation in pancreatic cancer. No approved targeted therapies are available for these patients, making this an area of significant unmet need,” said David Hong, M.D. of MD Anderson Cancer Center, principal investigator and lead author for the RMC-9805-001 presentation. “This is a challenging disease, but we observed a promising level of antitumor activity at generally tolerable doses in this Phase 1 study." Revolution Medicines will host an investor webcast on Friday, October 25, 2024 at 12:00 p.m. Eastern Time / 6:00 p.m. Central European Standard Time to discuss the RMC-6236 and RMC-9805 monotherapy data in PDAC presented at the EORTC-NCI-AACR (“Triple”) meeting. To participate in the live webcast, participants may register in advance here. A live webcast of the call will be available on the Investors section of Revolution Medicines’ website at https://ir.revmed.com/events-and-presentations. Following the live webcast, a replay will be available on the company’s website for at least 14 days. Pancreatic cancer is one of the most lethal malignancies, characterized by its typically late-stage diagnosis, resistance to standard chemotherapy, and high mortality rate. In the U.S., recent estimates indicate that in 2024, approximately 60,000 people will be diagnosed with pancreatic cancer, and about 50,000 people will die from this aggressive disease. The most common form of pancreatic cancer, pancreatic ductal adenocarcinoma (PDAC) and its variants, accounts for approximately 92% of all pancreatic cancer cases. Due to the lack of early symptoms and detection methods, approximately 80% of patients are diagnosed with PDAC at an advanced or metastatic stage. It is the most RAS-addicted of all major cancers, and more than 90% of patients have tumors that harbor RAS mutations. Metastatic PDAC remains one of the most common causes of cancer-related deaths in the U.S., with a five-year survival rate of approximately 3%. Revolution Medicines is a clinical-stage oncology company developing novel targeted therapies for RAS-addicted cancers. The company’s R&D pipeline comprises RAS(ON) inhibitors designed to suppress diverse oncogenic variants of RAS proteins. The company’s RAS(ON) inhibitors RMC-6236, a RAS(ON) multi-selective inhibitor, RMC-6291, a RAS(ON) G12C-selective inhibitor, and RMC-9805, a RAS(ON) G12D-selective inhibitor, are currently in clinical development. Additional development opportunities in the company’s pipeline focus on RAS(ON) mutant-selective inhibitors, including RMC-5127 (G12V), RMC-0708 (Q61H) and RMC-8839 (G13C), in addition to RAS companion inhibitors RMC-4630 and RMC-5552.

Oct. 21, 2024 -- Revolution Medicines, Inc. (Nasdaq: RVMD), a clinical-stage oncology company developing targeted therapies for patients with RAS-addicted cancers, today announced that the first patient has been dosed in RASolute 302, a Phase 3 registrational study of RMC-6236, a RAS(ON) multi-selective inhibitor, in patients with previously treated, metastatic pancreatic ductal adenocarcinoma (PDAC). RASolute 302 is a global, randomized, open-label Phase 3 study designed to evaluate the safety and efficacy of RMC-6236 monotherapy for patients with metastatic pancreatic cancer compared with standard of care chemotherapy. The trial is anticipated to enroll approximately 460 patients worldwide who had received one prior line of therapy with a 5-fluorouracil (5-FU)-based or gemcitabine-based regimen. The study design focuses on a core population of patients with PDAC harboring RAS mutations at position 12 (RAS G12X) and an expanded population that includes patients with tumors harboring RAS mutations at position G12 (RAS G12X), G13 (RAS G13X) or Q61 (RAS Q61X), or those without any identified targetable mutation. The dual primary endpoints for the study are progression-free survival (PFS) and overall survival (OS) in the core patient population. Key secondary endpoints include PFS and OS in the expanded population of patients. Additional information about RASolute 302 (NCT06625320) is available at clinicaltrials.gov. “Treating the first patient in RASolute 302 is a significant milestone for Revolution Medicines as we seek to revolutionize treatment for patients with RAS-addicted cancers,” said Mark A. Goldsmith M.D., Ph.D., chief executive officer and chairman of Revolution Medicines. “RMC-6236 is designed to directly inhibit RAS(ON) signaling, which is the primary oncogenic driver of pancreatic cancer. Supported by the encouraging initial PFS and OS observations and safety profile reported from the Phase 1 RMC-6236 monotherapy trial, the randomized RASolute 302 trial will formally assess the potential for this bold investigational drug to make a meaningful difference for people living with metastatic PDAC, one of the most difficult-to-treat cancers.” Pancreatic cancer is one of the most lethal malignancies, characterized by its typically late stage diagnosis, resistance to standard chemotherapy, and high mortality rate. In the U.S., recent estimates indicate that in 2024, approximately 60,000 people will be diagnosed with pancreatic cancer, and about 50,000 people will die from this aggressive disease.

Metastatic PDAC remains one of the most common causes of cancer-related deaths in the U.S., with a five-year survival rate of approximately 3%. RMC-6236 is an oral, direct RAS(ON) multi-selective inhibitor with the potential to help address a wide range of cancers driven by oncogenic RAS mutations. RMC-6236 suppresses RAS signaling by blocking the interaction of RAS(ON) with its downstream effectors. It does so across oncogenic RAS mutations G12X, G13X and Q61X, in major cancers including pancreatic ductal adenocarcinoma (PDAC), non-small cell lung cancer (NSCLC) and colorectal cancer (CRC).
