SAFFRON Phase III Trial Meets Both Endpoints
ORPATHYS plus TAGRISSO demonstrated statistically significant and clinically meaningful improvements in progression-free survival (PFS) and overall survival (OS) versus platinum-based chemotherapy in 338 patients with MET-driven EGFR-mutated NSCLC after progression on TAGRISSO.
-
First Global Phase III Win in This Setting
SAFFRON is the first global Phase III trial to show significant PFS and OS benefits in MET-driven EGFR-mutated lung cancer after TAGRISSO progression, supporting global registrations.
-
Safety Profile Consistent
No new safety findings; the safety profile was consistent with the known profiles of each medicine.
-
Next Steps: Regulatory Submissions
Data will be presented at a forthcoming medical meeting and shared with global regulatory authorities, with AstraZeneca leading commercialization.
Analysis · HCM · Life Sciences
The SAFFRON trial is the first global Phase III study to demonstrate statistically significant and clinically meaningful improvements in both progression-free survival and overall survival for a MET inhibitor combination in EGFR-mutated lung cancer after progression on TAGRISSO. This validates the combination's efficacy beyond the China-only SACHI trial and supports global regulatory filings. The positive OS result is particularly important because overall survival is the gold standard endpoint and often harder to achieve. With AstraZeneca as partner, this could expand ORPATHYS into a multi-billion dollar global market for MET-driven resistance, a common mechanism affecting roughly one in three patients on third-generation EGFR TKIs.
