FDA Approves Revolution Medicines Rasonque (Daraxonrasib) for Metastatic Pancreatic Adenocarcinoma

The FDA on Wednesday August 26, 2026 approved Rasonque (daraxonrasib, a once-daily oral pan-RAS inhibitor developed by Revolution Medicines) for adults with metastatic pancreatic adenocarcinoma who have received at least one prior systemic therapy or are not candidates for multi-agent chemotherapy. Approval was based on the Phase 3 RASolute 302 trial across 500 previously-treated patients showing median overall survival of 13.2 months on Rasonque versus 6.7 months on standard chemotherapy. The drug does not require a companion diagnostic and is approved for patients with or without an identifiable RAS tumor mutation. FDA granted Breakthrough Therapy and Orphan Drug designations plus Priority Review. Daraxonrasib is a small molecule and not a peptide; the approval matters to peptide-relevant readers because it hardens the oncology backdrop the neoantigen peptide vaccine class (Merck-Moderna intismeran, individualized long-peptide programs) is entering, and because it validates a new mechanism class in a tumor where five-year survival has stalled near 13% for two decades.

Protagonist and Takeda Bring Phase 3 VERIFY and Long-Term Rusfertide Data to EHA 2026 in Stockholm Through June 14

Protagonist Therapeutics (Nasdaq: PTGX) and Takeda are presenting four rusfertide abstracts at the 2026 European Hematology Association Congress in Stockholm (June 11-14), including analyses from the Phase 3 VERIFY study and long-term results from the Phase 2 REVIVE and THRIVE open-label extensions. The 32-week VERIFY primary analysis showed 76.9% of patients on rusfertide achieved a clinical response versus 32.9% on placebo; the 52-week dataset met the primary endpoint and all four key secondary endpoints. Rusfertide is a first-in-class subcutaneous hepcidin-mimetic peptide for polycythemia vera. The FDA accepted the rusfertide NDA in early 2026 with priority review and set a Q3 2026 PDUFA target action date.
