Preclinical discovery and clinical development of encorafenib for the treatment of melanoma.

Nearly 50% of patients with metastatic melanoma harbor a BRAFV600-mutation, which can be targeted with the use of BRAF and MEK inhibitors, either in the front-line or treatment-refractory setting. Encorafenib is the newest BRAF-inhibitor to have received FDA-approval in combination with the MEK inhibitor binimetinib.
The authors provide an overview of the preclinical development and the clinical trials that led to the use of encorafenib in BRAFV600-mutant melanoma. They also give discussion on its current use in clinical practice, providing their expert perspectives on the subject.
Preclinical research has provided strong rationale for upgrading encorafenib investigation into clinical development/testing. However, there is not yet enough data to determine where encorafenib may fit in comparison to other drugs in the same class, and ongoing trials will further define its role in the treatment of melanoma. Of note, there are ongoing studies that further explore the role of encorafenib + binimetinib such as in combination regimens with immunotherapy drugs, and in brain metastases.
