Phase II clinical trial, with two cohorts of patients included in parallel, all with melanoma BRAF mutated and brain metastases without previous local treatment in the brain. Cohort 1 will include patients with asymptomatic brain metastases and cohort 2 will include patients with symptomatic brain metastasis.
Name: encorafenib
Name: binimetinib
Name: Whole brain radiation therapy
Name: Radiosurgery/stereotactic radiosurgery
Description: iORR calculated as the proportion of patient with a best overall intracranial response of complete response (CR) or partial response (PR) before local treatment in cohort 1. The final statistical analysis of this endpoint is expected to be performed within 3 months after the local treatment of the last patient in cohort 1. This outcome will be assessed on day 56, and every 8 weeks up to 24 months after start of treatment
Measure: Intracranial objective response by RECIST 1.1 before local radiotherapy treatment in cohort 1 Time: 24 months after start of treatmentDescription: ORR calculated as the proportion of patient with a best overall intracranial response of complete response (CR) or partial response (PR) before local treatment in cohort 1.

Measure: Intracranial objective response by RECIST 1.1 before local radiotherapy treatment in cohort 2 Time: 24 months after start of treatmentDescription: Compared to baseline evaluation evaluated after 8 weeks since the start of treatment
Measure: Change on Quality of life at week 8 in both cohorts based on the EORTC QLQ 30 scale Time: 8 weeksDescription: Compared to baseline evaluation evaluated after 24 weeks since the start of treatment
Measure: Change on Quality of life at week 24 in both cohorts based on the EORTC QLQ 30 scale Time: 24 weeksAllocation: N/A
