Inclusion Criteria

Signed written informed consent
Male or female subjects aged 18 years
Histologically proven locally advanced or metastatic GIST. C-Kit (CD117) positive tumors detected by immunohistochemistry
Known mutational status KIT or PDGFRA
Documented disease progression (as per RECIST 1.1) within 3 months before study entry
No more than 3 previous lines of treatment, which must include imatinib and sunitinib
Performance status 2 at trial entry and an estimated life expectancy of at least 3 months
Disease must be measurable with at least 1 unidimensional measurable lesion by RECIST 1.1. Clinically and/or radiographically documented measurable disease within 21 days prior to registration
Adequate hematological function defined by the following laboratory tests results, obtained within 14 days prior to initiation of study treatment
\- white blood cell (WBC) count 3 109/L with absolute neutrophil count (ANC) 1.5 109/L
\- lymphocyte count 0.5 109/L
\- platelet count 100 109/L
\- hemoglobin 9 g/dL (patients may be transfused)
Adequate hepatic function defined by
\- total bilirubin level 1.5 the upper limit of normal range (ULN)
\- an AST level 2.5 ULN, and an ALT level 2.5 ULN or, for subjects with documented metastatic disease to the liver, AST and ALT levels 5 ULN
Serum creatinine 1.5 x ULN or creatinine clearance 50 ml/min on the basis of the Cockroft- Gault glomerular filtration rate estimation
(140-age) x (weight in kg) x (0,85 if female)/72x(serum creatinine in mg/dl)
No clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke (< 6 months prior to enrollment), myocardial infarction (< 6 months prior to enrollment), Uncontrolled hypertension (systolic blood pressure >150 mmHg and/or diastolic blood pressure >100 mmHg , unstable angina, congestive heart failure (2 New York Heart Association Classification medication) serious cardiac arrhythmia. All other significant diseases (e.g., inflammatory bowel disease), which, in the opinion of the investigator, might impair the subject's tolerance of trial treatment
Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial
Patients not receiving anticoagulant medication who have an International Normalized Ratio (INR) >1.5 or an activated partial thromboplastin time (aPTT) >1.5 x ULN within 7 days prior to first study treatment. Note: Patients receiving full dose oral or parenteral anticoagulants may be included in the study as long as anticoagulant dosing has been stable for at least 2 weeks prior to study entry and the appropriate coagulation monitoring tests are within local therapeutic limits
Effective contraception for both male and female subjects if the risk of conception exists. (Note: The effects of the study drugs on the developing human fetus are unknown. Thus, women of childbearing potential and men must agree to use effective contraception, defined as 2 barrier methods e.g. implants, injectables, combined oral contraceptives in combination with a barrier method, some intrauterine contraceptive devices, sexual abstinence, or a vasectomized partner;)
Availability of representative formalin-fixed paraffin-embedded (FFPE) tumor specimens in paraffin blocks

Exclusion Criteria

Concurrent anticancer treatment within 14 days before the start of trial treatment (e.g., cytoreductive therapy, radiotherapy [with the exception of palliative bone directed radiotherapy], immune therapy, or cytokine therapy except for erythropoietin); major surgery within 28 days before the start of trial treatment (excluding prior diagnostic biopsy); use of hormonal agents within 7 days before the start of trial treatment; or use of any investigational drug within 28 days before the start of trial treatment
Patients with PDGFRA D842V mutations are not eligible for this study

Subjects with active, known or suspected autoimmune disease. Subjects with vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll

Patients with past or resolved HBV infection, defined as having a negative HBsAg test and a positive total hepatitis B core antibody (HBcAb) test at screening, are eligible for the study
Active hepatitis C virus (HCV) infection, defined as having a positive HCV antibody test and positive HCV RNA test at screening
Active tuberculosis
Severe infection within 2 weeks prior initiation of study treatment, including, but not limited to, hospitalization for complications of infection, bacteriemia or severe pneumonia
