Brief summary

This phase II trial investigates how well adding hydroxychloroquine to the standard treatment of dabrafenib and trametinib works to overcome resistance and delay disease progression in treating patients with stage IIIC or IV BRAF V600E/K melanoma. Hydroxychloroquine may cause cell death in tumor cells that rely on a process called "autophagy" for survival. Dabrafenib and trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving hydroxychloroquine together with dabrafenib and trametinib may work better than dabrafenib and trametinib alone to shrink and stabilize the cancer.

Detailed description

PRIMARY OBJECTIVE: I. To determine the rate of one year progression-free survival (PFS) when hydroxychloroquine sulfate (hydroxychloroquine) or placebo is added to dabrafenib mesylate (dabrafenib) and trametinib dimethyl sulfoxide (trametinib) in advanced BRAFV600E/K melanoma with elevated lactate dehydrogenase (LDH). SECONDARY OBJECTIVES: I. To compare the PFS of both arms. II. To evaluate the best overall response rate by treatment arm. III. To evaluate the complete response (CR) rate by treatment arm. IV. To evaluate the adverse event rate by treatment arm. V. To evaluate overall survival (OS) by treatment arm. OUTLINE: Patients are randomized to 1 of 2 arms. ARM A: Patients receive dabrafenib mesylate orally (PO) twice daily (BID), trametinib dimethyl sulfoxide PO once daily (QD), and hydroxychloroquine sulfate PO BID on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. ARM B: Patients receive dabrafenib mesylate PO BID, trametinib dimethyl sulfoxide PO QD, and placebo PO BID on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 1 year.
