A prospective, multicenter, randomized, open-label, active-controlled, two-parallel groups, phase 3 study to compare the efficacy and safety 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 - Not applicable

9.Patient able and willing to comply with study procedures as per protocol
10.Patient able to understand, and willing to sign, and date the written informed consent form at screening visit prior to any protocol-specific procedures

Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

(b) lesion(s) diameter is = 2 cm
(c) radiation therapy (gamma knife) was completed = 4 weeks prior to baseline
(d) surgery was completed =4 weeks prior to baseline
(e) lesions assessed by follow-up scan (or MRI if MRI performed before brain therapy) = 1 month after brain therapy are considered under control at baseline
