Patient case: 26-year-old male with Liposarcoma. Genetic variant: MDM2 Amplification. Other conditions: None.

Clinical trial: Efficacy of Nilotinib in First or Second Line Treatment of Primary Melanomas Stage III Unresectable Melanomas.

Summary: 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.

Detailed description: 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  Patients with progressive disease after 3 months therapy will be withdrawn.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

Eligibility: Inclusion Criteria:
