Orpathys plus Tagrisso shows survival benefit in lung cancer
HUTCHMED reported positive phase 3 trial results for Orpathys (savolitinib) plus Tagrisso (osimertinib) in EGFR-mutated non-small cell lung cancer. The combination showed significant improvements in progression-free and overall survival compared to chemotherapy. The study focused on patients with MET overexpression or amplification, a common resistance mechanism. HUTCHMED and AstraZeneca plan to pursue global registrations for the combination.
