Pancreatic Cancer | Proton w/FOLFIRINOX-Losartan for Pancreatic Cancer

Pancreatic Cancer research study

What is the primary objective of this study?

This is a Phase II clinical trial, which tests the safety and effectiveness of an investigational combination of drugs to learn whether the combination of drugs works in treating a specific cancer. \"Investigational\" means that the combination of drugs is being studied. It also means that the FDA has not yet approved it for your type of cancer. Proton beam radiation therapy is an FDA approved radiation delivery system. Conventional radiation therapy uses photons to treat cancer before patients undergo surgery to remove the tumor. In this study we are using radiation with protons, which spares surrounding tissue and organs from radiation. Proton radiation delivers radiation to the area requiring radiation with no dose beyond the treatment area. This may reduce side effects that patients would normally experience with conventional radiation therapy. Researchers in the laboratory have discovered pathways inside cancer cells which contribute to the growth and survival of tumors. The FOLFIRINOX chemotherapy regimen is a combination of the drugs 5-fluorouracil, leucovorin and oxaliplatin. These chemotherapy drugs, along with the chemotherapy drug capecitabine, work by blocking these pathways and thereby preventing tumor growth. Capecitabine is FDA approved to be used alone or with other drugs to treat other types of advanced cancer, but not pancreatic cancer. In past research studies, FOLFIRINOX followed by radiation therapy with capecitabine has been identified as the most effective and active chemotherapy for patients with cancer that is spreading, and this is why we are using it to treat your type of cancer. Losartan is classified as an angiotensin-receptor blocker (ARB), and is FDA approved for use in people with high blood pressure. Recent studies in people with different types of cancer, including pancreatic cancer, have shown that combining chemotherapy drugs with an ARB can help reduce/stop tumor growth more effectively than chemotherapy alone. Losartan has been used in previous research studies, and information from those research studies suggests that this drug in combination with FOLFIRINOX and capecitabine may be better at treating your type of cancer. In this research study, we seek to determine whether combining FOLFIRINOX with Losartan before proton radiation therapy will be more efficient at controlling the growth of or shrinking your tumor than just FOLFIRINOX alone.
