Descriptive Information

• Brief Title: A Clinical Trial of Three Study Medicines (Encorafenib, Binimetinib, and Pembrolizumab) in Patients With Advanced or Metastatic Melanoma
• Official Title: A PHASE 3, RANDOMIZED, DOUBLE-BLIND STUDY OF ENCORAFENIB AND BINIMETINIB PLUS PEMBROLIZUMAB VERSUS PLACEBO PLUS PEMBROLIZUMAB IN PARTICIPANTS WITH BRAF V600E/K MUTATION-POSITIVE METASTATIC OR UNRESECTABLE LOCALLY ADVANCED MELANOMA

Brief Summary

The purpose of this study is to learn about the effects of three study medicines (encorafenib, binimetinib, and pembrolizumab) given together for the treatment of melanoma that:

• is advanced or metastatic (spread to other parts of the body);
• has a certain type of abnormal gene called "BRAF"; and
• has not received prior treatment.

All participants in this study will receive pembrolizumab at the study clinic once every 3 weeks as an intravenous (IV) infusion (given directly into a vein). In addition, half of the participants will take encorafenib and binimetinib orally (by mouth) at home every day.

Participants may receive pembrolizumab for up to two years. Those participants taking encorafenib and binimetinib can continue until their melanoma is no longer responding. The study team will monitor how each participant is doing with the study treatment during regular visits at the study clinic.

• Detailed Description: This study will compare the efficacy, safety, and tolerability of encorafenib and binimetinib plus pembrolizumab (Triplet Arm) versus placebo plus pembrolizumab (Control Arm) in participants with metastatic or unresectable locally advanced BRAF V600E/K mutation-positive melanoma. The study will have an open-label safety lead-in (SLI) phase to determine the safety recommend Phase 3 dose (RP3D) and pharmacokinetics (PK) of encorafenib and binimetinib plus pembrolizumab combination therapy prior to initiation of the randomized Phase 3 part of the study. Two dose levels of encorafenib in combination with binimetinib plus pembrolizumab will be explored in parallel. A minimum of 12 evaluable participants will be enrolled per dose level. During the double-blind randomized Phase 3 part of the study, approximately 600 eligible participants will be randomized in a 1:1 ratio to the Triplet Arm (at RP3D determined in the SLI) or Control Arm (approximately 300 participants per arm). Randomization will be stratified by prior systemic adjuvant therapy and stage of disease by AJCC (ED8).
