Genotype-Selective Combination Therapies for Melanoma Identified by High-Throughput Drug Screening

Abstract

We have used drug combinatorial screening to identify effective combinations for mutant BRAF melanomas, including those resistant to vemurafenib, and mutant RAS melanomas that are resistant to many therapies. Mechanisms governing the interactions of the drug combinations are proposed, and in vivo xenografts show the enhanced benefit and tolerability of a mutant RAS -selective combination, which is currently lacking in the clinic.
