Exploratory Platform Trial to Evaluate Immunotherapy Combinations With Chemotherapy for the Treatment of Patients With Previously Untreated Metastatic Pancreatic Adenocarcinoma

This is an open-label, non-randomized, exploratory platform trial designed to assess the safety and antitumor activity of immunotherapy, in combination with standard of care chemotherapy, in participants with mPDAC who have not received prior therapy. Where supportive mechanistic data are available, immunotherapy may also be combined with other treatment modalities (eg, radiation). Each cohort of this platform trial will test a different immunotherapy combination and consist of up to 2 stages: an initial stage (Stage 1) to evaluate safety, biomarkers, and/or clinical activity of the combination and an expanded cohort (Stage 2), when warranted, based on the safety, clinical activity, and/or biomarker results from Stage 1. The Sponsor intends to modify and/or add new combinations to the protocol as data emerge from scientific findings, in this and other trials.

This trial will be conducted in participants with histologically or cytologically documented diagnosis of mPDAC, with measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, who have not received prior systemic therapy for their disease in the metastatic setting. Participants must have adequate organ and hematologic function and acceptable performance status. Participants must consent to tumor biopsies, including a pre-treatment (baseline) and on-treatment samples.
