PHARAOH-A will determine the efficacy and tolerability of the combination of savolitinib and osimertinib in patients with EGFR-mutated, MET-overexpressed and/or amplified advanced NSCLC following disease progression on first- or second-line osimertinib. The primary endpoint is objective tumour response rate (RECIST 1.1), with ctDNA dynamics and clearance to be examined in correlative studies. Patients with untreated and asymptomatic brain metastases can be included in the study. The study will also open to recruitment in Taiwan with first patient in expected in 2027.
