This clinical trial is focused on studying a type of skin cancer called melanoma, specifically when it has spread to other parts of the body or cannot be removed by surgery. The study is looking at patients with a specific genetic change known as the BRAF V600E/K mutation. The trial will test the effectiveness of a combination of medications: Encorafenib, Binimetinib, and Pembrolizumab. Encorafenib is taken as a capsule, Binimetinib as a tablet, and Pembrolizumab is given through an infusion, which means it is delivered directly into the bloodstream through a vein.

The purpose of the study is to compare the effects of the combination of Encorafenib, Binimetinib, and Pembrolizumab against a placebo combined with Pembrolizumab. Participants will be randomly assigned to receive either the combination of the three medications or the placebo with Pembrolizumab. The study will last for up to 24 months, during which participants will receive regular treatments and check-ups to monitor their health and the progress of the melanoma.

This trial aims to determine if the combination of these medications can improve outcomes for patients with this specific type of melanoma. The study will also assess the safety of the medication combination and monitor any side effects that may occur. Participants will be closely observed by healthcare professionals throughout the study to ensure their well-being and to gather important information about the treatment’s effectiveness.
