| Measure | Time frame |
|---|---|
| Main Objective: The primary objective is to compare the efficacy of masitinib at 7.5 mg/kg/day to dacarbazine in the treatment of patients with non-resectable or metastatic stage 3 or stage 4 melanoma carrying a mutation in the juxta membrane domain of c-kit (c-kit JM). The primary endpoint is Progression Free Survival (PFS). ;Secondary Objective: Secondary objectives are to compare the efficacy and safety of masitinib at 7.5 mg/kg/day to dacarbazine The secondary endpoints are: Efficacy: • Overall Survival (OS) • Survival rate at week 6, 12, 18, 24 and every 12 weeks • PFS rate at week 6, 12, 18, 24 and every 12 weeks • Time To Progression (TTP) and TTP rate at week 6, 12, 18, 24 and every 12 weeks • Best response rate, Objective response rate (CR + PR) and Disease control rate (CR + PR + SD) Quality of life : assessment at week 6, 12, 18 and 24 and every 12 weeks • ECOG performance status • EORTC QLQ-C30 Safety profile using the NCI CTCAE v4.0 classification ;Primary end point(s): Primary endpoint: Progression Free Survival (PFS) defined as the delay between the date of randomization to the date of documented progression (according to m-RECIST) or any cause of death during the study | — |
