This is a phase 1 dose-escalation study of nilotinib in combination with fixed-dose dabrafenib and trametinib regimen for patients with metastatic or unresectable melanoma carrying a BRAF V600 mutation and have relapsed on a BRAF/MEK inhibitor therapy. The goal is to assess the toxicity and tolerability and determine the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) of the combination of nilotinib with dabrafenib and trametinib or with encorafenib and binimetinib. Additionally, this study will assess pharmacokinetic parameters of dabrafenib and nilotinib when used in combination.
This is a phase 1 dose-escalation study of nilotinib in combination with a fixed-dose of dabrafenib and trametinib or with encorafenib and binimetinib. The first week, patients will be treated with dabrafenib (150mg, twice daily) and trametinib (2mg, once daily), or encorafenib (450 mg, daily) and binimetinib (45 mg twice daily). After 7 days, when both drugs have achieved steady-state levels and there is maximal induction of CYP3A4, nilotinib will be added, and all three drugs dosed concurrently for the rest of the study. Optional plasma pharmacokinetic (PKs) samples for dabrafenib and nilotinib will be obtained at baseline, weekly for the first four weeks, and at regular study visits for the duration of the trial. Tissue core biopsies and correlative plasma samples will be obtained at baseline, and 2 weeks after the start of nilotinib.

Patients will begin dabrafenib (150mg PO BID) and trametinib (2mg PO once daily) or encorafenib (450 mg PO) and binimetinib (45 mg PO BID) on day one and will continue for 28 days. After 7 days, nilotinib will be added at 100mg PO BID and will continue for 21 days. For each subsequent cycle, nilotinib will be given for 28 days.

RECRUITINGPercentage of Patients Experiencing Dose Limiting Toxicities
Percentage of patients who experienced dose-limiting toxicities associated with Nilotinib as defined by the study protocol.
Time frame: 28 days
Dose-Adjusted Steady State Concentration of Dabrafenib
The dose-adjusted steady state concentrations (Css) of dabrafenib will be calculated on day 8 (dabrafenib alone) compared to day 15 (dabrafenib + nilotinib).
Time frame: 15 days
Change in Nilotinib Concentration
Plasma concentrations of Nilotinib will be measured on day 8 (pre-Nilotinib) and day 29.
Time frame: 1 month
Duration of Response
Duration of overall response will be determined by the time measurement criteria are met for complete response (CR) or partial response (PR) - whichever is first recorded - until the first date that recurrent or progressive disease is objectively documented.
Time frame: 12 months
