ATP-150

The goal of this clinical trial is to test an experimental treatment (immunotherapy) in pancreatic cancer patients. The main research objectives are:
* to evaluate if the KISIMA-02 treatment is safe and well-tolerated (first part)
* to evaluate if the KISIMA-02 treatment has an impact on the time to observe a possible reappearance of the tumor (second part)
Participants will receive:
i) a therapeutic protein vaccine ATP150 or ATP 152 ii) a viral vector VSV-GP154 iii) an immune checkpoint inhibitor Ezabenlimab In the second part of the study, researchers will compare treatment group versus observational group.
