What was measured

ORR was defined as the percentage of participants who had achieved a confirmed best overall response (CR or PR) per RECIST version 1.1. Both CR and PR must be confirmed by repeat assessments performed no less than 4 weeks after the criteria for response were first met. CR was defined by the disappearance of all non-lymph node target lesions (where all target lesions were recorded with a length of 0 mm, and any pathological lymph nodes \[recorded as target lesion\] must have reduction in short axis to \<10 mm) and the complete disappearance of all non-target lesions (where all non-target lesions were marked "Absent", and all lymph nodes must be non-pathological in size \[\<10 mm in short axis\]). PR was defined by a 30% or more decrease in SOD of target lesions, taking as reference the baseline SOD. ORR according to derived investigator assessment was calculated with the exact 2-sided Clopper-Pearson 95% CI.

Analysis population: Analysis population included all participants who received at least 1 dose of study intervention.

Groups in this outcome

Treatment-Naive

Treatment-naïve participants with BRAF V600E-mutant metastatic NSCLC were enrolled to receive encorafenib 450 mg QD and binimetinib 45 mg BID in 28-day (±3 days) cycles and continued until the participants met the protocol-defined criteria for treatment withdrawal.

Previously Treated

Patients who had received 1) first-line treatment with standard platinum-based chemotherapy, or 2) first-line treatment with an anti-PD-1/PD-L1 inhibitor given alone, or in combination with platinum-based chemotherapy, or in combination with immunotherapy (eg, ipilimumab) with or without platinum-based chemotherapy were enrolled to receive encorafenib 450 mg QD and binimetinib 45 mg BID was to be administered in 28-day (±3 days) cycles and continued until the participants met the protocol-defined criteria for treatment withdrawal.
