An Open-label Study of Encorafenib + Binimetinib in Patients With BRAFV600-mutant Non-small Cell Lung Cancer

Summary

This is an open-label, multicenter, non-randomized, Phase 2 study to determine the safety, tolerability and efficacy of encorafenib given in combination with binimetinib in patients with BRAFV600E-mutant metastatic non-small cell lung cancer (NSCLC). Patients who are either treatment-naïve, OR who have received 1) first-line treatment with standard platinum-based chemotherapy, OR 2) first-line treatment with an anti-programmed cell death protein 1 (PD-1)/programmed cell death protein ligand 1 (PD-L1) inhibitor given alone or in combination with platinum-based chemotherapy will be enrolled.
