Proton w/FOLFIRINOX-Losartan for Pancreatic Cancer
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.

Hide Detailed Description
If you are willing to participate in this research study, you will be asked to undergo some screening tests and procedures to confirm that you are eligible. Many of these tests and procedures are likely to be part of regular cancer care and may be done even if it turns out that you do not take part in the research study. If you have had some of these tests or procedures recently, they may or may not have to be repeated. These tests and procedures will include a medical history, routine physical exam, performance status, assessment of your tumor, routine blood tests, a blood sample to check your kidney function and a serum or urine pregnancy test if applicable. If these tests show that you are eligible to participate in the research study, you will begin the study treatment. If you do not meet the eligibility criteria, you will not be able to participate in this research study.
There are two phases to this study. Phase I involves FOLFIRINOX and Losartan. The treatment plant will begin with 8 cycles of FOLFIRINOX. Each cycle is 14 days, or 2 weeks long. FOLFIRINOX is comprised of four drugs: Oxaliplatin, irinotecan, fluorouracil and leucovorin. On Day 1 of each 14 day cycle, you will receive oxaliplatin via IV infusion over a period of 2 hours. Irinotecan will be administered via IV infusion on Day 1 of each cycle over a period of 90 minutes.
You will receive fluorouracil (5FU) on Day 1 of each cycle via IV infusion over a period of 2-4 minutes. You will then be fitted with an ambulatory infusion pump that will be delivered continuously over 46-48 hours.
In addition to these infusions, FOLFIRINOX will always be administered along with a two hours IV infusion of leucovorin, a drug composed of reduced folic acid, which helps enhance the effects of chemotherapy. You will be give leucovorin through a vein in your arm for 2 hours a day on Day 1 of each cycle.
You will also receive an injection of Neulasta after each FOLFIRINOX treatment. Neulasta is used to reduce the chance of infection from chemotherapy by boosting your white blood cell count. It will be administered 24-48 hours after your FOLFIRINOX infusion (on Day 3 or 4).
You will take one dose of Losartan by mouth every day during Phase I for all 8 cycles of FOLFIRINOX. If the dose of Losartan given to you during the first week does not give you any serious side effects, your dose will be increased once for the remainder of Phase I. We have provided a drug diary for you with instructions on how to take this tablet and what to do incase of any missed or vomited doses. We will monitor your response to treatment with a chest/abdominal CT after four cycles of FOLFIRINOX therapy (8 weeks).
Phase II involves Restaging/Proton Beam Radiation Therapy and Capecitabine. At this time your study doctor will assess for any progress in your cancer after the FOLFIRINOX + Losartan treatment again via CT scan. If your cancer has progressed, you will be removed from the study and continue with standard of care treatment. If it has not progressed, you will continue to the proton radiation therapy and capecitabine phase of the study.
During this phase you will receive proton beam radiation therapy at the Francis H. Burr Proton Therapy center for 1 week, Monday through Friday. Each visit is expected to take 30-45 minutes.
During the week of proton radiation therapy and for the week after, you will take capecitabine by mouth on Monday through Friday, for a total of ten days. You will be given a drug diary with instructions on how to take capecitabine and what to do in case of a missed or vomited dose.
You will receive the following tests and procedures at various time points during both portions of the study. These tests and procedures will include: routine blood tests, blood sample to check kidney function, CA19-9 and CEA blood tests, Chest CT/Abdominal-Pelvic CT, assessment for side effects, vital signs, performance status, routine physical exam and blood pressure monitoring.
After the final dose of study drug you will come into the clinic for follow-up visits for some assessments every 3 months until your cancer progresses. You will undergo the following tests: routine physical exam, vital signs, performance status, routine blood tests, assessment for side effects. In addition you are required to have a chest and abdominal/pelvic CT every 6 months for the first two years, and yearly for years 3-5. We would like to keep track of your medical condition for the rest of your life. We would like to do this by calling you on the telephone once a year to see how you are doing. Keeping in touch with you and checking on your condition every year helps us look at the long term effects of the research study.
