This study aims to compare the efficiency and safety of masitinib at a dose of 12 mg/kg/dag to those of a standard treatment for GIST: sunitinib (Sudent) at a dose of 50 mg/day for 4 consecutive weeks followed by weeks without medication. Masitinib and sunitinib will be administred untill disease progression in patients with GIST after receiving imatinib (Glivec)
