Encorafenib and biNimetinib Followed by CEmiplimab and FiAnLimab in Patients With BRAF Mutant melanOma and Symptomatic Brain Metastases

Brain metastases in patients with advanced and metastatic melanoma are a frequent complication and a significant cause of morbidity and mortality in this patient population. As the incidence of brain metastases continues to increase in patients with metastatic melanoma, it is urgent that the investigators identify effective therapies. ENCEFALO is a Phase II, single arm, multicentre clinical trial designed to evaluate the activity of encorafenib plus binimetinib followed by cemiplimab and fianlimab in patients with BRAF mutated melanoma and symptomatic brain metastases, following the simon design Two-stage minimax. The objective main is to evaluate the 6 month intracranial progression-free survival (icPFS) proportion of Encorafenib plus Binimetinib followed by Cemiplimab plus Fianlimab in patients with BRAF-mutated melanoma and symptomatic brain metastases according RECIST criteria The trial hypothesis is: For patients with BRAF-mutated melanoma and symptomatic brain metastases, an induction treatment with encorafenib and binimetinib (EB) for about two months (i.e. 8 weeks) followed by cemiplimab plus fianlimab (CF) would allow a 6 month icPFS rate of 40% in comparison to historical control of 20% based on CM204 symptomatic arm (Tawbi et al 2021).
