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.

- Number of Participants With R0 Resection [ Time Frame: At the time of surgery (approximately 4 months after the start of treatment) ]The number of participants that received treatment with proton radiation along with FOLFIRINOX-Losartan and then subsequently underwent attempted surgery and achieved R0 resection. R0 resection means that no cancer cells were seen microscopically at the resection margin.
- Progression-Free Survival [ Time Frame: From the start of treatment until death or progression, median duration of 17.5 months ]
To determine the progression free survival of patients with locally advanced disease who receive FOLFIRINOX-Losartan and proton beam radiation therapy. Disease progression was assessed using Response Evaluation Criteria in Solid Tumors (RECIST 1.1).
Progressive disease (PD): At least a 20% increase in the sum of the longest diameter (LD) of target lesion, taking as reference the smal lest sum LD recorded since the treatment started or the appearance of one or more new lesions (new lesions must be > slice thickness).
- Overall Survival for FOLFIRINOX + Proton Beam Radiation [ Time Frame: 2 years ]To determine overall survival in patients treated with preoperative FOLFIRINOX and proton beam radiation therapy
- Overall Survival for FOLFIRINOX Without Proton Radiation [ Time Frame: 2 years ]To determine the overall survival of patients with locally advanced disease who receive FOLFIRINOX-Losartan without proton radiation (i.e. patients who demonstrate progression at restaging)
- Determine Toxicity FOLFIRINOX-Losartan [ Time Frame: 2 years ]To determine the toxicity of FOLFIRINOX-Losartan in patients with locally advanced pancreatic disease
- Determine Toxicity of FOLFIRINOX-Losartan and Proton Beam Radiation [ Time Frame: 2 years ]To determine the toxicity of FOLFIRINOX-Losartan and proton beam radiation in patients with locally advanced pancreatic cancer.
- Rate of Downstaging [ Time Frame: 2 years ]To determine the rate of downstaging to surgical resection of FOLFIRINOX-Losartan followed by proton radiation in patients with locally advanced pancreatic cancer
- Determine Correlation of Somatic Gene Mutations and Outcome [ Time Frame: 2 years ]To determine the correlation between a panel of somatic genetic mutations (SNaPSHOT) and outcome in locally advanced pancreatic cancer treated with FOLFIRINOX-Losartan +/- proton beam radiation/capecitabine
- Determine Correlation Between Circulating Biomarkers and Outcome [ Time Frame: 2 years ]To determine the correlation between circulating biomarkers of TGF-B1 downregulation, including circulating Collagen I levels, and outcome in locally advanced pancreatic cancer treated with FOLFIRINOX-Losartan +/- proton beam radiation/capecitabine.
- Describe Quality of Life, Symptom Burden and Mood [ Time Frame: 2 years ]Describe quality of life, symptom burden and mood in the study population
- To Measure Utilization of Health Services [ Time Frame: 2 years ]To measure utilization of health services (ER, hospital and ICU visits) in the study population
