Brief Summary:
The objective of this study is to evaluate the safety, tolerability, and antitumor activity of oleclumab (MEDI9447) in combination with or without durvalumab plus chemotherapy in subjects with metastatic pancreatic cancer.

Condition or disease Intervention/treatment Phase
Carcinoma Metastatic Pancreatic Adenocarcinoma Biological: oleclumab Biological: durvalumab Drug: gemcitabine Drug: nab-paclitaxel Combination Product: oxaliplatin Combination Product: leucovorin Combination Product: 5-FU Phase 1 Phase 2

Detailed Description:
This is a Phase 1b/2, multicenter, open-label, dose-escalation, and dose-expansion study to assess the safety, preliminary antitumor activity, immunogenicity, and PK of oleclumab with or without durvalumab in combination with chemotherapy administered in subjects with metastatic PDAC. Subjects with previously untreated metastatic PDAC (1L metastatic PDAC) with be enrolled in Cohort A. Subjects with metastatic PDAC previously treated with gemcitabine-based chemotherapy (without exposure to 5-FU, capecitabine, or oxaliplatin, 2L metastatic PDAC) will be enrolled in Cohort B. The study consists of 2 parts, dose escalation (part 1) and dose expansion (Part 2).
