• I-4. Tumor type:

  1. advanced solid tumors or lymphomas for which an anti PD-1/PD-L1 has shown efficacy (e.g., with high microsatellite instability or MSI-H) but is not available in the center/country (no marketing authorization, no reimbursement, no early access program, etc.) or;
  2. rare tumors with reported significant activity of anti-PD-1 (e.g., Tertiary Lymphoid Structures positive or TLS+ sarcomas, alveolar soft part sarcomas, etc.), or;
  3. PD-L1 positive tumors.
• I-5. Prior treatment with at least one line of systemic therapy and no standard of care available.
• I-6. Evaluable or measurable disease according to RECIST 1.1/RECIL.

• I-7. Adequate organ function:

  1. Bone marrow: neutrophils ≥ 1.5 x 109/L, hemoglobin ≥ 90 g/L, platelets ≥ 100 x 109/L.
  2. Renal function: serum creatinine ≤ 1.5 ULN or CKD-EPI creatinine clearance ≥ 30 mL/min.
  3. Liver function: AST and ALT ≤ 3 ULN, bilirubin ≤ 1.5 ULN. In case of liver metastasis: AST and ALT ≤ 5 ULN. For patients with Gilbert's syndrome total bilirubin ≤ 3 ULN or direct bilirubin ≤ 1.5 ULN.
