This research study is studying a combination of drugs with radiation therapy as a possible treatment for Microsatellite Stable Colorectal Cancer, Pancreatic Cancer, or MSI High Colorectal Cancer.
The interventions involved in this study are:
Full description
This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that the intervention is being studied.
The FDA (the U.S. Food and Drug Administration) has not approved nivolumab for this specific disease but it has been approved for other uses.
The FDA (the U.S. Food and Drug Administration) has not approved ipilimumab for this specific disease but it has been approved for other uses.
Researchers hope to study the effects of the combination of Nivolumab and Ipilimumab. Many cancers use specific pathways (such as PD-1/PD-L1 and CTLA-4) to evade the body's immune system. Nivolumab and ipilimumab work by blocking the PD-1/PD-L1 and CTLA-4 pathways and thus releasing the brakes on the immune system so it can stop or slow cancer.
Ipilimumab and Nivolumab are both antibodies. An antibody is a cell that attaches to other cells to fight off infection. The antibodies in ipilimumab work by not allowing cancer cell growth. The antibodies in nivolumab work by causing programmed cell death of the cancer cells. Radiation therapy is believed to increase the likelihood of response of immunotherapy (the prevention/treatment of a disease through an immune response).
In this research study, the investigators are studying the combination of nivolumab, ipilimumab and radiation therapy on participants with microsatellite stable colorectal cancer, pancreatic cancer, or MSI high colorectal cancer. The combination of these study drugs have been tested and optimized for safety and is currently being tested in multiple disease types. The study drugs have not been tested and optimized in combination with radiation therapy. The investigators believe that through the combination of the study drugs and radiation therapy the body may produce an immune response to stop the cancer cells from growing.

Table 1 Adequate Organ Function Laboratory Values
System Laboratory Value
Hematological
Renal
Hepatic
Coagulation
International Normalized Ratio (INR) or Prothrombin Time (PT)
Activated Partial Thromboplastin Time (aPTT) ≤1.5 X ULN unless subject is receiving anticoagulant therapy
as long as PT or PTT is within therapeutic range of intended use of anticoagulants
≤1.5 X ULN unless subject is receiving anticoagulant therapy
as long as PT or PTT is within therapeutic range of intended use of anticoagulants
Creatinine clearance should be calculated per institutional standard.
Women of childbearing potential (WOCBP) must use appropriate method(s) of contraception. WOCBP should use an adequate method to avoid pregnancy for 5 months (30 days plus the time required for nivolumab to undergo five half-lives) after the last dose of investigational drug.
Women of childbearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG)
Women must not be breastfeeding
Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year. Men receiving nivolumab and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 7 months after the last dose of investigational product. Women who are not of childbearing potential, ie, who are postmenopausal or surgically sterile as well as azoospermic men do not require contraception
Ability to understand and the willingness to sign a written informed consent document.
Stable dose of dexamethasone 2 mg or less for 7 days prior to initiation of treatment
One previously unirradiated lesion amenable to radiotherapy 8 Gy x 3 and can meet dose constraints, and another unirradiated measurable lesion > 1 cm in size outside the radiation field that can be used as measurable disease
Colorectal patients must have documentation of microsatellite status. Immunohistochemistry (IHC) is acceptable.
Colorectal patients must have received prior Fluorouracil (5FU), Irinotecan and Oxaliplatin (any combination) or have a contraindication to receiving these agents.
Pancreas patients must have progressed on at least 1 prior line of chemotherapy
