A Study to Test the Benefit of Vitamin B5 in Patients With Melanoma

C-PAN is an essential nutrient as it is required for the synthesis of CoA, a key cofactor in the tricarboxylic acid cycle and fatty acid metabolism, as well as for the synthesis of acyl carrier protein. Pantothenate appears to be safe in humans with studies describing the administration of doses up to 10 grams per day over prolonged periods of time; hence, no upper limit for tolerability has been established. In this study, oral supplement consisting of 2000 mg daily of C-PAN will be administered to a single cohort of patients.

Nivolumab is an ICI, a type of immunotherapy. It is a monoclonal antibody that binds to the protein PD-1 on the surface of immune cells called T cells. Nivolumab 1 mg/kg every 3 weeks for up to 4 cycles (upon patient´s tolerability) followed by maintenance Nivolumab 3 mg/kg (or fixed dose 240 mg) every 2 weeks or Nivolumab 6 mg/kg (or fixed dose 480 mg) every 4 weeks.

Ipilimumab is an ICI, a type of immunotherapy. It is a monoclonal antibody that binds to the protein CTLA-4 on immune cells called T cells. Ipilimumab 3 mg/kg every 3 weeks for up to 4 cycles.
