FDA granted Breakthrough Therapy Designation to zoldonrasib for adult patients with KRAS G12D‑mutated locally advanced or metastatic non‑small cell lung cancer who had prior anti‑PD‑1/PD‑L1 therapy and platinum‑based chemotherapy. The designation is based on Phase 1 RMC‑9805‑001 monotherapy cohort data showing an objective response rate of 61% and disease control rate of 89% in 18 evaluable patients, with median time to response of 1.4 months and an acceptable safety profile.
The approval expands Revolution Medicines’ portfolio of Breakthrough Designations, adding to those already granted for daraxonrasib and elironrasib. The company’s tri‑complex inhibitor platform, which creates a ternary complex between RAS, a small molecule, and cyclophilin A, enables targeting of the active RAS(ON) state—a historically undruggable target. The new designation validates the platform’s ability to address the larger KRAS G12D and pan‑RAS market, which represents a significant unmet need.
Management emphasized the clinical significance of the data. CEO Mark A. Goldsmith said the breakthrough underscores the unmet need for patients with KRAS G12D cancers and confirms the company’s strategy to bring RAS(ON) inhibitors to market. The data also support the company’s guidance that it expects to advance zoldonrasib into a pivotal Phase 2 study in the second quarter of 2026.
The market reacted strongly to the news. Analysts noted that the Breakthrough designation accelerates the drug’s development timeline and could shorten the time to approval, potentially opening a sizable market for a first‑in‑class therapy. The designation also strengthens Revolution Medicines’ competitive position against other RAS‑targeted programs and may influence future investment decisions in the oncology space.
Financially, Revolution Medicines reported cash and marketable securities of $1.93 billion as of September 30 2025 and reiterated its full‑year 2025 GAAP net loss guidance of $1.03 billion–$1.09 billion. The company’s focus on R&D investment remains high, but the Breakthrough designation is expected to improve the company’s long‑term valuation prospects by providing a clear path to a potentially high‑revenue therapy.
