FDA Approves Capmatinib and Companion Assay

The Food and Drug Administration has approved capmatinib (Tabrecta) to treat adults with metastatic non–small cell lung cancer (NSCLC) harboring MET exon 14 skipping mutations, as detected by an FDA-approved test.

The FDA also approved the FoundationOne CDx assay (F1CDx) as a companion diagnostic for capmatinib. F1CDx is a next-generation sequencing-based, in vitro diagnostic device that detects several mutations, including MET exon 14 skipping mutations.

Capmatinib is a selective, reversible inhibitor of MET tyrosine kinase and the first treatment FDA-approved for NSCLC with MET exon 14 skipping mutations.

Capmatinib was granted accelerated approval based on overall response rate and response duration in the GEOMETRY mono-1 trial, the FDA said. Results from this trial were recently presented at the AACR Virtual Annual Meeting I.

The phase 2 trial enrolled 97 patients with metastatic NSCLC and confirmed MET exon 14 skipping mutations, 69 of whom were previously treated and 28 of whom were treatment naive. The patients received capmatinib at 400 mg orally twice daily until disease progression or unacceptable toxicity.

The overall response rate was 68% in the treatment-naive patients and 41% in the previously treated patients. The median duration of response was 12.6 months and 9.7 months, respectively, according to the FDA.

The most common adverse events (occurring in at least 20% of patients) were peripheral edema, nausea, fatigue, vomiting, dyspnea, and decreased appetite.

The full prescribing information for capmatinib is available for download from the FDA website.

The FDA granted the approval of capmatinib to Novartis Pharmaceuticals Corporation and the approval of the F1CDx companion diagnostic to Foundation Medicine.
