Dabrafenib, Trametinib and Hydroxychloroquine in Treating Patients with Stage IV Metastatic Melanoma

Trial Status: administratively complete

This phase I/II trial studies the side effects and best dose of hydroxychloroquine when given together with dabrafenib and trametinib and to see how well they work in treating patients with stage IV melanoma that has spread to other places in the body. Dabrafenib and trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Sometimes when dabrafenib and trametinib are given, the tumor cells activate a stress response called autophagy. Autophagy provides resistance to dabrafenib and trametinib treatment over time making them less effective. Giving hydroxychloroquine with dabrafenib and trametinib may reduce drug resistance and allow more tumor cells to be killed.
