• Patient is unwilling or unable to comply with study procedures.
• Patients with impaired decision-making capacity.

• Histologically confirmed, metastatic pancreatic adenocarcinoma. Patients with adenosquamous carcinoma and mixed adenocarcinoma/neuroendocrine carcinoma (MANEC) of the pancreas are eligible, but pure neuroendocrine neoplasms are excluded.
• Progression of disease or intolerance to at least one standard line of chemotherapy.
  • Patients who are candidate for an anti-PD-1 antibody due to Microsatellite instability -High (MSI-H) or tumor mutational burden (TMB)-high status must have been treated with this drug before being eligible for this trial.
  • Prior treatment with an anti-PD(L)-1 antibody is allowed unless this therapy was stopped due to an immune-related adverse event.
  • Patients who are candidate for a poly (ADP-ribose) polymerase (PARP) inhibitor due to a germline BRCA1/2 mutation must have been treated with this drug before being eligible for this trial.
• At least one tumor measurable by CT scan. Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as >20 mm with conventional techniques or >10 mm with spiral CT scan.
