A Phase 1b Study to Evaluate the Safety, Tolerability and Preliminary Efficacy of a Heterologous Prime Boost Vaccination (ATP150/ATP152/ATP162, VSV-GP154) and Ezabenlimab (BI 754091) in Patients With Pancreatic Ductal Adenocarcinoma.
This study is open to adults with advanced pancreatic cancer. The study tests a type of immunotherapy. It is a protein treatment combined with a virus that may kill cancer cells and help the immune system fight cancer. The immunotherapy is combined with a study medicine called ezabenlimab. Ezabenlimab is an antibody that may also help the immune system fight cancer. The purpose is to find the highest dose of the immunotherapy that people with pancreatic cancer can tolerate when taken alone or together with ezabenlimab (Part A and B). To find out, researchers look at the number of participants with certain severe health problems. The purpose of Part C is to check whether the immunotherapy combined with ezabenlimab may increase survival. Participants are put randomly into 2 groups. One group receives the immunotherapy combined with ezabenlimab and the other group receives standard treatment. Researchers compare the results between the groups. Participants can stay in the study as long as they tolerate the treatment or up to 1 year. During that time, they regularly visit the site. At all visits, the doctors closely check the health of the participants and note any severe health problems.
