Paraffin-embedded tumor block must be provided by all subjects during screening period. - Screening of mutations done in exon 11, 9, 13 and 17 in KIT gene and in 12 and 18 exons of PDGFR gene - Subjects must have at least one measurable lesion according to RECIST v1.1 criteria. A lesion in a previously irradiated area is eligible to be considered as measurable disease as long as there is objective evidence of progression of the lesion prior to study enrolment. - Adequate bone marrow, liver, and renal function as assessed by the following laboratory requirements conducted within 7 days of starting study treatment: Total Bilirubin = 1.5 x the upper normal limit (UNL). Documented Gilbert Syndrome is allowed if total bilirubin is mildly elevated (=6mg/dl).

Subjects who are being treated with an anti-coagulant, such as warfarin or heparin, will be allowed to participate provided that no prior evidence of an underlying abnormality in these parameters exists. Close monitoring of at least weekly evaluations will be performed until INR and PTT are stable based on a pre-dose measurement as defined by the local standards of care. Platelet count =100000mm3, hemoglobin (Hb) = 9.0 g/dl, absolute neutrophil count (ANC) =1500/mm3. Blood transfusions to meet the inclusion criteria will not be allowed. Alkaline phosphatase limit = 2.5 x UNL (= 5x UNL for subjects with disease involving the liver) - Women of childbearing potential and men must agree to use adequate contraception from the moment of signing the Informed Consent Form until at least 3 months after the last study drug administration. The investigator or a designated associate is requested to advise the subject on how to achieve an adequate birth control. Adequate contraception is defined in the study as any medically recommended method (or combination of methods) as per standard of care. - Women of childbearing potential must have a blood or urine pregnancy test performed a maximum of 7 days before start of study treatment, and a negative result must be documented before start of study treatment
