Description

Summary

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.

Official Title

A Phase 1b Study to Evaluate the Safety, Tolerability and Preliminary Efficacy of ATP150/ATP152, VSV-GP154 and Ezabenlimab (BI 754091) in Patients With KRAS G12D/G12V Mutated Pancreatic Ductal Adenocarcinoma (KISIMA-02)

Details

This is an open-label, phase 1b study to evaluate the safety, tolerability, immunogenicity and preliminary efficacy of a heterologous prime-boost vaccine (protein and viral vector) regimen without/with the PD-1 inhibitor Ezabenlimab.

COMPLETED - Part A (metastatic and locally advanced PDAC patients) Cohort A: ATP150/ATP152 and VSV-GP154 treatment

ONGOING - Part B (locally advanced and resected PDAC patients) Cohort B: ATP150/ATP152, Ezabenlimab and VSV-GP154 treatment Cohort B1, B2, B3: dose escalation

NOT STARTED YET - Part C (resected PDAC patients) Cohort C: ATP150/ATP152, Ezabenlimab and VSV-GP154 treatment (treatment versus observational arm)
