Descriptive Information
Brief Title  ICMJE A Study of Avelumab In Combination With Axitinib in Patients With Unresectable/Metastatic Gastrointestinal Stromal Tumor After Failure of Standard Therapy
Official Title  ICMJE A Phase II, Single Arm Study of Avelumab In Combination With Axitinib in Patients With Unresectable/Metastatic Gastrointestinal Stromal Tumor After Failure of Standard Therapy - AXAGIST
Brief Summary To assess anti-tumor activity of avelumab in combination with axitinib in patients with unresectable/metastatic GIST after progression on second or third line treatment (after failure on at least of imatinib and sunitinib) in terms of progression-free survival (PFS)
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 2
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Gastrointestinal Stromal Tumors
Intervention  ICMJE Drug: Axitinib

Avelumab 10 mg/kg will be administered every two weeks. Avelumab is administered as a 1-hour iv infusion, diluted with 0.9% saline solution; Axitinib 5 mg should be taken orally twice daily approximately 12 hours apart with or without food. They should be swallowed whole with a glass of water. If the patient vomits or misses a dose, an additional dose should not be taken. The next prescribed dose should be taken at the usual time.

The duration of treatment cycle is 28 days.

Eligibility Criteria  ICMJE

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.
