Encorafenib, Binimetinib and Palbociclib in BRAF-mutant Metastatic Melanoma CELEBRATE

Summary

This is an open-label, phase IB, non-randomised study consisting of a dose escalation phase and expansion phase, evaluating the safety, tolerability and preliminary efficacy of the combination of encorafenib, binimetinib and palbociclib in patients with BRAF-mutant metastatic melanoma. Dose escalation phase: Previously treated or treatment-naïve patients will be evaluated after the first cycle for dose-limiting toxicities to ascertain the recommended phase 2 dose (RP2D) of encorafenib, binimetinib and palbociclib. Expansion phase: Two cohorts of patients will be further evaluated for the efficacy and safety of the RP2D of palbociclib with encorafenib and binimetinib. Cohort 1 will include patients naïve to both BRAF and MEK inhibitors. Cohort 2 will include patients with either primary or acquired resistance to both BRAF and MEK inhibitors.
