Study to evaluate the efficacy and safety of capmatinib as a single-agent treatment for subjects with advanced/metastatic (stage IIIB or IV) non-small cell lung cancer (NSCLC) who had wild-type epidermal growth factor receptor (EGFR wt) (for exon 19 deletions and exon 21 L858R substitution mutations), anaplastic lymphoma kinase (ALK)-negative rearrangement, and mesenchymal epithelial transition (MET) mutations leading to exon 14 deletion (referred to as MET mutation hereafter) and/or MET amplification.
This was a Phase II, multicenter, open-label study. Patients were enrolled in different cohorts based on their MET status (amplification and/or mutation) and prior treatment status: Cohort 1a, Cohort 1b, Cohort 2, Cohort 3, Cohort 4, Cohort 5a, Cohort 5b, Cohort 6, and Cohort 7. MET mutation (by RT-PCR) and/or MET amplification status by gene copy number (GCN, by FISH) was determined by central laboratory. Patients in Cohorts 1, 2, 3, and 4 had previously failed 1 or 2 prior lines of systemic therapy, while patients enrolled in Cohorts 5 and 7 were treatment-naïve for advanced disease/metastatic disease. Patients enrolled in Cohort 6 had failed 1 prior line of systemic therapy for advanced/ metastatic disease. Patients with MET mutation were enrolled in Cohort 4 (pre-treated), Cohort 5b (treatment naïve) or Cohort 7 (treatment naïve expansion cohort of Cohort 5b), irrespective of their MET GCN. The enrollment in expansion Cohort 7 started after the completion of enrollment in Cohort 5b. Patients without MET mutation, were enrolled in Cohorts 1a, 1b, 2, 3 (pre-treated) or 5a (treatment naïve), based on their MET GCN. Patients enrolled in Cohort 6 (expansion cohort of Cohort 1a and Cohort 4) had either MET GCN ≥10 without MET mutation (Cohort 6.1) or MET mutation, irrespective to their MET GCN (Cohort 6.2). The enrollment in Cohort 6 started upon enrollment completion of the respective Cohort 1a or Cohort 4. All participants in the study received oral capmatinib 400 mg twice daily. A treatment cycle was defined as 21 days. Treatment with capmatinib continued until patient experienced any of the following: disease progression according to RECIST 1.1 as determined by investigator and confirmed by Blinded Independent Review Committee (BIRC), unacceptable toxicity that precluded further treatment, treatment discontinuation at the discretion of the Investigator or patient, lost to follow-up, or death. Treatment with capmatinib was allowed beyond RECIST 1.1-defined disease progression (as determined by investigator and confirmed by BIRC) if, in the judgment of the investigator, there was evidence of clinical benefit and the patient wished to continue on the study treatment. All patients continued to have safety evaluations for 30 days after the last dose of study treatment. Patients who discontinued treatment with capmatinib for any reason other than disease progression, as determined by the investigator and confirmed by BIRC, death, withdrawal of consent for further assessments, or being lost to follow-up, continued to have tumor assessments (post-treatment efficacy follow-up) until disease progression confirmed by BIRC, death, withdrawal of consent for further assessments, or lost to follow-up. All patients who discontinued treatment with capmatinib were followed for survival (post-treatment survival follow-up) until death, loss to follow-up, withdrawal of consent to survival follow-up, or the end of the study.

Overall Response Rate (ORR) by Blinded Independent Review Committee (BIRC) Assessment
Percentage of participants with a best overall response defined as confirmed complete response (CR) or partial response (PR) by BIRC assessment per RECIST 1.1. CR: Disappearance of all non-nodal target and non-target lesions. In addition, any pathological lymph nodes assigned as target and non-target lesions must have a reduction in short axis to \< 10 mm PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters.
