Brief Summary
This trial is a prospective, randomized (1:1 ratio), multicenter, comparative and phase II study, conducted in patients with unresectable advanced gastrointestinal stromal tumors (GIST) after failure of imatinib (disease progression),sunitinib and regorafenib (either disease progression or intolerance) In the first arm, patients will be treated with imatinib + atezolizumab (experimental arm), whereas in the second arm, patients will be treated with imatinib alone (control arm). The comparison between this two arms will allow to compare whether or not atezolizumab and imatinib is efficient for disease control, in terms of Progression-Free Survival improvement.
Eligibility Criteria
INCLUSION CRITERIA : I1. Male or female ≥ 18 years at the day of consenting to the study; I2. Patients must have histologically confirmed diagnosis of GIST (within the French Reference Network in Pathology of Sarcomas - RRePS network); I3. Locally advanced or metastatic disease confirmed as measurable according to the RECIST V1.1 (Appendix 1); I4. Patients who previously failed to at least imatinib, sunitinib and then regorafenib. Failure is defined for Imatinib as progressive disease, and for sunitinib and regorafenib as progressive disease and/or intolerance; I5. Performance Status of the ECOG of 0 or 1; I6. Adequate bone marrow and organ function defined by the following laboratory results: a. Bone marrow: i. Hemoglobin ≥ 9.0 g/dl, ii. Absolute Neutrophils Count (ANC) ≥ 1.5 G/l, iii. Lymphocytes count ≥ 0.5 G/l, iv. Platelets ≥ 100 G/l; b. Coagulation: i. Prothrombin time ≤ 1.5 x Upper Limit of the Normal (ULN) for patients without therapeutic anticoagulation. Patients with therapeu
