Amplification of cMET leading to oncogenic signaling occurs in ≈4% of non-small cell lung cancer (NSCLC) cases. Mutations in cMET leading to exon 14 deletion (cMETÎex14) are also an actionable target in NSCLC. Capmatinib (INC280) is a potent and selective cMET inhibitor that has shown strong evidence of antitumor activity in an ongoing Phase I study in patients (pts) with EGFR wild-type (WT) advanced NSCLC harboring cMET dysregulation, including high-level cMET amplification (fluorescence in situ hybridization [FISH] gene copy number [GCN] ≥5), and cMETÎex14.
This multicenter Phase II four-cohort study (ClinicalTrials.gov identifier NCT02414139) was designed to confirm the clinical activity of capmatinib in pretreated pts with advanced NSCLC according to cMET amplification and cMETÎex14. Eligible pts (≥18 years of age, Eastern Cooperative Oncology Group Performance Status 0–1) must have ALK-negative, EGFR-WT (for activating mutations including exon 19 deletion, and L858R mutation) stage IIIB/IV NSCLC (any histology), and have received 1–2 prior lines of therapy for advanced disease (no prior cMET inhibitor). Centrally assessed cMET amplification and mutation status will be used to assign pts to one of four cohorts (≈69 pts each; N ≈ 276): 1: cMET GCN ≥6 2: cMET GCN ≥4 and <6 3: cMET GCN <4 4: cMETÎex14 mutation regardless of GCN Capmatinib 400 mg tablets will be administered twice daily on a continuous dosing schedule 12 hours apart. Primary and key secondary objectives are to evaluate overall response rate (ORR) and duration of response (DOR), respectively (assessed by blinded independent review). Other secondary objectives include investigator-assessed ORR, DOR, time to response, disease control rate, progression-free survival, safety, and pharmacokinetics. Enrollment is ongoing.
