Full Press Release Details
Breakthrough Therapy Designation based on promising early clinical evidence observed with daraxonrasib in patients with pancreatic ductal adenocarcinoma (PDAC)
RASolute 302, a Phase 3 registrational study of daraxonrasib in patients with previously treated metastatic PDAC, expected to substantially complete enrollment this year
REDWOOD CITY, Calif., June 23, 2025 (GLOBE NEWSWIRE) -- Revolution Medicines, Inc. (Nasdaq: RVMD), a late-stage clinical oncology company developing targeted therapies for patients with RAS-addicted cancers, today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation to daraxonrasib, the company’s RAS(ON) multi-selective inhibitor, for previously treated metastatic PDAC in patients with KRAS G12 mutations.
The Breakthrough Therapy Designation is based on encouraging data from the Phase 1 RMC-6236-001 clinical trial evaluating daraxonrasib in patients with previously treated metastatic PDAC.
“This Breakthrough Therapy Designation underscores the enormous need for new treatments for patients with pancreatic cancer and highlights the potentially important role the investigational drug, daraxonrasib, may have in helping patients living with this disease,” said Mark A. Goldsmith M.D., Ph.D., chief executive officer and chairman of Revolution Medicines. “We look forward to substantially completing enrollment of the RASolute 302 study this year to enable an expected readout in 2026, and should the results support it, working closely with the FDA and other regulatory agencies around the world to bring daraxonrasib to patients as quickly as possible.”
Breakthrough Therapy Designation is intended to expedite the development and review of potential new medicines designed to treat serious conditions and address significant unmet medical needs. The medicine needs to have shown encouraging preliminary clinical evidence that demonstrates substantial improvement on a clinically significant endpoint over available medicines.
More than 90% of patients living with PDAC have tumors carrying a RAS cancer driver mutation with ~85% carrying a KRAS G12 mutation. Revolution Medicines is currently enrolling patients in RASolute 302, a global Phase 3 registrational study of daraxonrasib in patients with previously treated metastatic PDAC. 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.
About Pancreatic Cancer and Pancreatic Ductal Adenocarcinoma
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 cancer1, 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 cases2. 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 commonly RAS-addicted of all major cancers, and more than 90% of patients have tumors that harbor RAS mutations3. 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%4.
Daraxonrasib (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. Daraxonrasib suppresses RAS signaling by blocking the interaction of RAS(ON) with its downstream effectors. It does so by targeting oncogenic RAS mutations G12X, G13X and Q61X that are common drivers of major cancers, including pancreatic ductal adenocarcinoma (PDAC), non-small cell lung cancer (NSCLC) and colorectal cancer (CRC).
