E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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).
|
|
E.2.2 | Secondary objectives of the trial |
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

E.4 | Principal exclusion criteria |
1.Pregnant, or nursing female patient
2.Patient with other malignancies from which the patient has been continuously disease-free for < 3 years, with the exception of melanoma, cervical carcinoma in situ, basal cell or squamous cell skin cancer, ductal or lobular carcinoma in situ of the breast
3.Patient with active brain metastases are not eligible. Patients with treated brain metastases are eligible if :
(a) presence of 3 brain lesions or less
(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
4.Patient refractory to dacarbazine defined as patient presenting a disease progression within 3 months from the start of a previous dacarbazine therapy.
5.Prior treatment with a tyrosine kinase c-kit inhibitor
6.Patient with grade III/IV cardiac failure as defined by the New York Heart Association Criteria (i.e., congestive heart failure, or myocardial infarction within six months before baseline)
7.Patient with clinically uncontrolled infectious diseases including HIV or AIDS-related illness
8.Major surgery or radiation therapy within four weeks of starting the study treatment

10.Previous radiotherapy, chemotherapy and/or previous adjuvant therapy with interferon, vaccines or therapy with IL-2 or GM-CSF within 4 weeks prior to baseline. Those patients will require a four weeks wash-out period before baseline. Similarly, any previous treatment with an investigational agent will require a wash-out period of four weeks before baseline
