Efficacy of Nilotinib in First or Second Line Treatment of Primary Melanomas Stage III Unresectable Melanomas.
Efficacy of Nilotinib in First or Second Line Treatment of Primary Melanomas Stage III Unresectable Melanomas.
NILOMEL is a phase II multicentric uncontrolled open national trial assessing the efficacy of
 Nilotinib in first or second line treatment of primary melanomas , stage III unresectable
 melanomas, or Stage IV melanomas with c-KIT mutation or amplification. The primary objective
 is overall response rate (partial and complete response) according to RECIST 1.1 criteria,
 assessed using CT-SCAN (stage IV melanoma) or MRI (unresectable melanoma) after 6 months
 therapy with Nilotinib 800 mg/d. Secondary objectives include:

 -  Disease control rate (complete, partial response and stable disease)

 -  Metabolic response

 -  Tolerance NCI CTCAE Version 3.0

 -  Biomarkers associated to response and disease control.
NILOMEL is a phase II multicentric uncontrolled open national trial assessing the efficacy of
 Nilotinib in first or second line treatment of primary melanomas , stage III unresectable
 melanomas, or Stage IV melanomas with c-KIT mutation or amplification (in case of c-KIT
 amplification, no B-RAF nor N-Ras mutation should be detected). The primary objective is
 overall response rate (partial and complete response) according to RECIST 1.1 criteria,
 assessed using CT-SCAN (stage IV melanoma) or MRI (unresectable melanoma) after 6 months
 therapy with Nilotinib 800 mg/d. Secondary objectives include:

 -  Disease control rate (complete, partial response and stable disease) according to RECIST

 -  Metabolic response rate (TEP-SCAN)

 -  Tolerance NCI CTCAE Version 3.0

 -  Biomarkers associated to response and disease control (evaluated at M0, M1 and M6).
 Protein analysis of c-KIT, PI3K, MAPK and STAT signalling pathways as well as PDGFR and
 Ephrin signalling pathways.

 Patients with progressive disease after 3 months therapy will be withdrawn. Patient with
 stable disease after 3 months will continue Nilotinib until evaluation at 6 months. Patients
 with stable disease or progressive disease at 6 months will continue Nilotinib until
 progression.

 The trial has been planned using a one-stage design (Fleming TR) . We considered that a
 response rate under 7.5% would define the null hypothesis of no efficacy . To detect a
 response rate of 30% or more with power 90% using a one-sided test at the 0.05 level, 25
 patients have to be recruited.

 Accrual for 2.5 years total study duration: 3 years
