Brief Summary
This is a multicenter, randomized open-label Phase 2 study to assess the safety, efficacy and pharmacokinetic (PK) of 2 dosing regimens of encorafenib + binimetinib combination in patients with BRAFV600-mutant melanoma with brain metastasis. Approximately 100 patients will be enrolled, including 9 patients in a Safety Lead-in of the high-dose treatment arm. After a Screening Period, treatment will be administered in 28-day cycles and will continue until disease progression, unacceptable toxicity, withdrawal of consent, start of subsequent anticancer therapy, death.

For patients receiving local therapy to all brain lesions (including WBRT), progression of pre-existing lesions based on RECIST 1.1 (\> 20% increase in longest diameter on baseline scan) or new measurable lesions are required. For patients receiving local therapy for some but not all lesions, disease progression based on RECIST 1.1 is not required as long as there are remaining brain lesions that are measurable and not previously treated.

- All patients (Safety Lead-In and Phase 2): May have received prior immunotherapy.
- All patients (Safety Lead-In and Phase 2): If receiving concomitant corticosteroids must be on a stable or decreasing dose for at least 2 weeks prior to first dose of study treatment (up to a total daily dose of 4mg of dexamethasone or equivalent).

- Adequate bone marrow, organ function and laboratory parameters
You may not qualify if:
- Patients with symptomatic brain metastasis.
- Uveal or mucosal melanoma.
- History of or current leptomeningeal metastases.
- Treatment with SRS or craniotomy within 14 days prior to start of study treatment, or treatment with whole-brain radiation within 28 days prior to study treatment. Patients who received local therapy should have complete recovery with no neurological sequelae.
- Either of the following:
- Radiation therapy to non-brain visceral metastasis within 2 weeks prior to start of study treatment;
- Continuous or intermittent small-molecule therapeutics or investigational agents within 5 half-lives of the agent (or within 4 weeks prior to start of study treatment, when half-life is unknown).
- Patients treated in the adjuvant setting with BRAF or MEK inhibitor(s) \< 6 months prior to enrollment. Patients who received BRAF or MEK inhibitors in the metastatic setting are excluded.
