Study Overview

Olaparib and Durvalumab (MEDI4736) in Patients with Metastatic Pancreatic Cancer and DNA Damage Repair Genes Alterations

Patients with metastatic pancreatic cancer and germline mutation in BRCA have benefit of therapy with PARP inhibitors. In addition, some studies have demonstrated that PDL-1 inhibitors synergize therapeutically with PARP inhibitors in tumours with homologous repair deficiency. Our hypothesis is that those patients with alterations in DNA damage repair genes (somatic and germline BRCA1, BRCA2, PALB2, RAD51C, RAD51D and other functional DDR genes) and who have benefit from platinum based therapy in first line might obtain an increased therapeutic effect with the combination of olaparib and durvalumab. This is an open-label, single-arm, multicentric phase II clinical trial of a combination of durvalumab and olaparib in patients with metastatic pancreatic cancer with alterations in DDR genes, who have had benefit with platinum-based chemotherapy in first line setting. The primary objective is to investigate the efficacy of this combination in terms of ORR. Patients will be eligible for the study based on alterations in a panel of specific DDR genes including BRCA1, BRCA2, PALB2, RAD51C, RAD51D and other DDR genes, as determined by a local assay according to local practice or by the central laboratory (if local assay is not available).
