The present invention relates to a method for treating a subject suffering from melanoma resistant by administering to said subject an inhibitor of NAMPT. Using a global metabolic profiling, inventors have showed that in addition to glycolysis, the BRAF inhibitor, PLX4032, promoted a complex metabolic rewiring of melanoma cells, including protein catabolism and fatty acid synthesis. Importantly, they observed that PLX4032 reduced the levels of nicotinamide adenine dinucleotide (NAD+), an important redox co-factor in numerous metabolic processes, including glycolysis, tricarboxylic acid cycle (TCA) cycle, glutamate metabolism and fatty acid betaoxidation. Pharmacological or genetic inhibition of NAMPT impaired melanoma cell growth, whereas the overexpression of NAMPT dampened the antiproliferative effect of PLX4032. In vivo, the inhibition of NAMPT also prevented the xenograft development of PLX4032-sensitive and -resistant melanoma cells, identifying NAMPT as a potential target for BRAFi-resistant melanomas.
