What this trial studies

This clinical trial evaluates the immune response generated by durvalumab and oleclumab in patients with resectable pancreatic ductal adenocarcinoma (PDAC) prior to surgical intervention. It is a multi-site study conducted in Canada, focusing on the potential benefits of these immunotherapies in enhancing the effectiveness of surgery. Participants will receive the treatments before their scheduled surgery, with the aim of assessing immune activity and overall outcomes. The study includes specific eligibility criteria to ensure that participants are suitable for the interventions.

Who should consider this trial

Good fit: Ideal candidates are adults with resectable pancreatic ductal adenocarcinoma and an ECOG performance status of 0 or 1.

Not a fit: Patients who have previously received immune-mediated therapies or other anticancer treatments shortly before the trial may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve surgical outcomes and overall survival for patients with pancreatic cancer.

How similar studies have performed: Other studies have shown promising results with similar immunotherapy approaches in various cancers, suggesting potential for success in this context.
