This study evaluates the combination of Savolitinib and Durvalumab in patients with EGFR wild-type locally advanced or metastatic non-small cell lung cancer. Adults aged 18 and older with measurable tumors, typically carrying MET gene alterations, may take part. The study is in Phase 2 and is currently active but not recruiting new participants.
