On January 8, 2026 Revolution Medicines, Inc. (Nasdaq: RVMD), a late-stage clinical oncology company developing targeted therapies for patients with RAS-addicted cancers, reported that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation to zoldonrasib, a RAS(ON) G12D-selective inhibitor, for the treatment of adult patients with KRAS G12D-mutated locally advanced or metastatic NSCLC who have been previously treated with anti-PD-1/PD-L1 therapy and platinum-based chemotherapy.

The Breakthrough Therapy Designation is based on data from the monotherapy cohort of the Phase 1 RMC-9805-001 clinical trial evaluating zoldonrasib in patients with advanced KRAS G12D solid tumors. Results from the monotherapy cohort of the trial have demonstrated a robust clinical profile, including encouraging antitumor activity and acceptable safety and tolerability.
"The Breakthrough Therapy Designation for zoldonrasib, our RAS(ON) G12D-selective covalent inhibitor – the first ever granted for an investigational drug specifically targeting the RAS G12D mutation – underscores the significant unmet need for patients with KRAS G12D cancers, which currently lack any approved targeted therapies," said Mark A. Goldsmith, M.D., Ph.D., chief executive officer and chairman of Revolution Medicines. "This recognition expands upon prior designations for the RAS(ON) multi-selective inhibitor daraxonrasib and G12C-selective inhibitor elironrasib, further recognizing the promise of our first three clinical-stage RAS(ON) inhibitors as potentially transformative therapies for people living with RAS-addicted cancers."
Zoldonrasib is an innovative tri-complex inhibitor that binds to cyclophilin A, creating a complex that selectively recognizes and inhibits the active, oncogenic RAS G12D(ON) mutant. Revolution Medicines is evaluating zoldonrasib as a monotherapy and combination treatment across multiple tumor types and lines of therapy.
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. Pursuant to FDA guidelines, the medicine needs to have shown encouraging preliminary clinical evidence that demonstrates substantial improvement on a clinically significant endpoint over available medicines.
About Non-Small Cell Lung Cancer
Non-small cell lung cancer (NSCLC) accounts for 80%-85% of all lung cancers, with more than 197,000 people diagnosed in the U.S. each year.1,2,3 Despite treatment advancements, NSCLC remains a leading cause of cancer-related mortality worldwide, primarily due to its late-stage diagnosis and limited response to conventional therapies. G12D is the most common oncogenic driver of human cancers and represents 4% of NSCLC cases.
