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)

Phase 1 Interventional Amal Therapeutics · NCT05846516

This study is testing a new combination of immunotherapy treatments for pancreatic cancer patients with specific KRAS mutations to see if it can help them feel better and improve their outcomes.

What this trial studies

This clinical trial aims to assess the safety and efficacy of a novel immunotherapy regimen in patients with pancreatic ductal adenocarcinoma (PDAC) harboring KRAS G12D or G12V mutations. Participants will receive a combination of a therapeutic protein vaccine (ATP150 or ATP152), a viral vector (VSV-GP154), and an immune checkpoint inhibitor (Ezabenlimab). The study is divided into phases, with the first part focusing on safety and tolerability, while the second part will compare treatment outcomes against an observational group. The trial includes both advanced and resected PDAC patients who have undergone prior treatments.

Who should consider this trial

Good fit: Ideal candidates are patients with histologically confirmed PDAC and specific KRAS mutations who have completed prior treatments and have no evidence of disease progression.

Not a fit: Patients who are not yet recovered from surgery or have other malignancies within the last three years may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat pancreatic cancer.

How similar studies have performed: Other studies have shown promise with immunotherapy approaches in pancreatic cancer, but this specific combination is novel.
