Melanoma Clinical Trial
Nilotinib Plus Dabrafenib/Trametinib in Metastatic Melanoma
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. 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. The first week, patients will be treated with dabrafenib (150mg, twice daily) and trametinib (2mg, once 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. 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.
