Losartan and Nivolumab in Combination With FOLFIRINOX and SBRT in Localized Pancreatic Cancer

Study Overview
=================
Brief Summary
-----------------
This research study is studying a combination of interventions as a possible treatment for pancreatic tumor. The interventions involved in this study are: FOLFIRINOX which is made up of 4 different drugs: 5-Fluorouracil (5-FU) Oxaliplatin Irinotecan Leucovorin Losartan Nivolumab Radiation Therapy Surgery

Detailed 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 approved FOLFIRINOX as a treatment option for this disease. The FDA has not approved losartan or nivolumab for this specific disease but they have been approved for other uses. FOLFIRINOX is a combination of 4 chemotherapy agents that may help shrink your tumor before surgery. Losartan is a drug that is used to lower blood pressure. Nivolumab is an antibody (a cell that attaches to other cells to fight off infection) that may cause programmed cell death of cancer cells. Radiation therapy is believed to increase the likelihood of response of immunotherapy (the prevention/treatment of a disease through an immune response).

Eligibility Criteria
-----------------
Inclusion Criteria: Histologically confirmed localized pancreatic adenocarcinoma; borderline/potentially resectable or locally advanced. Borderline resectable is defined by the NCCN as tumors with venous involvement of the SMV/portal vein demonstrated tumor abutment with or without impingement and narrowing of the lumen, either tumor thrombus or encasement but with suitable vessel proximal and distal to the area of vessel involvement, allowing for safe resection or reconstruction; gastroduodenal artery encasement up to the hepatic artery with either short segment encasement or direct abutment of the hepatic artery, without extension to the celiac axis; or tumor abutment of the SMA not to exceed greater than 180 degrees of the circumference of the vessel wall. Tumors involving retroperitoneal structures that can be surgically removed (i.e. kidney), will also be included. Localized is defined as no extrapancreatic disease, no evidence (on CT) of involvement of the celiac axis or SMA, no evidence (CT or MRI) of occlusion of the SMV or SMPV confluence, no evidence of gross peritoneal or distant metastases on staging laparoscopy or laparotomy. Locally advanced unresectable disease is defined by the NCCN as: Tumors of the head that have greater than 180 degrees of SMA encasement or any celiac abutment, unreconstructable SMV or portal occlusion, or aortic invasion or encasement. Tumors of the body with SMA or celiac encasement of greater than 180 degrees, unreconstructable SMV or portal occlusion, or aortic invasion. Tumors of the tail with SMA or celiac encasement of greater than 180 degrees. Irrespective of location, all tumors with evidence of nodal metastasis outside of the resection field are deemed unresectable. Age > 18 years ECOG performance status 0-1 Baseline Systolic Blood Pressure (SBP) > 100 mm Hg. This is based on the average of two values - separate seated, resting measurements taken five minutes apart. BP does not need to be checked in both arms unless a reading is below 110 mm Hg, in which case the other arm can be checked as well. If BP is checked in both arms, the higher value is deemed accurate for calculating the average. Normal organ and marrow function as defined below: absolute neutrophil count ≥ 1,500/mm3 platelets ≥ 100,000/mm3 total bilirubin ≤ 1.5 x institutional upper limit of normal if no biliary stenting has been done OR 2.0 x upper limit of normal if patient is s/p biliary stenting OR two down trending values AST(SGOT)/ALT(SGPT) ≤ 2.5 × institutional upper limit of normal Potassium (not hemolyzed) < 5 mmol/L creatinine ≤ 1.5 mg/ dL OR creatinine clearance ≥ 30 mL/min (as estimated by Cockcroft Gault Equation) (140 - age [yrs]) (body wt [kg]) -Creatinine clearance for males = ------------ (72) (serum creatinine [mg/dL]) Creatinine clearance for females = 0.85 x male value Women of childbearing potential (WOCBP) must use appropriate method(s) of contraception. WOCBP should use an adequate method to avoid pregnancy for 5 months 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) within 24 hours prior to the start of nivolumab 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 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 If applicable, must be on a stable dose of dexamethasone 2 mg or less for 7 days prior to initiation of treatment Exclusion Criteria: NOTE: Patients enrolled to the randomized portion of the study (arms 1 thru 3) may not be already treated on ACE or ARB therapy for hypertension or renal protection (with diabetes) at the time of enrollment. If patients are receiving ACE or ARB therapy, they may ONLY be considered for the exploratory arm, Arm 4. Serious concomitant systemic disorders incompatible with the study (at the discretion of the investigator), such as significant cardiac or pulmonary morbidity e.g. congestive heart failure, symptomatic coronary artery disease and cardiac arrhythmias not well controlled with medication) or myocardial infarction within the last 12 months, ongoing infection as manifested by fever. Pregnant or lactating women. Women of childbearing potential with either a positive or no pregnancy test (serum or urine) at baseline. (Postmenopausal women must have been amenorrheic for at least 12 months to be considered of non-childbearing potential.)

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of participants with R0 resection | R0 resection is defined as microscopically negative margins determined by histopathologic assessment of the resection specimen. The R0 resection rate will be analyzed among all eligible patients, including those not resected due to early progression, death or off-study. | Up to 8 months after baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression-free survival | Progression-free survival is defined as the time from the date of randomization (or registration on Arm 4) to first objective documentation of progressive disease (distant or local) or death. Disease status is evaluated using RECIST (Response Evaluation Criteria in Solid Tumors). Disease progression is defined as having at least a 20% increase in the sum of the longest diameter (LD) of target lesion, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. | From randomization until the time of progression or death, up to approximately 6 years | 
| Overall survival | Overall Survival (OS) is defined as the time from randomization (or registration on Arm 4) to death due to any cause, or censored at date last known alive. | From randomization until the time of death, up to approximately 6 years | 
| Pathologic complete response | The proportion of participants that achieved a pathologic complete response. Pathologic complete response is defined as the disappearance of all target lesions, as confirmed by a pathologist evaluating the tissue samples removed during surgery. | Up to 8 months after baseline | 
| Number of participants with treatment related serious adverse events | Adverse events are assessed using Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Adverse events are considered to be related to treatment if the Investigator deems them to be either possibly, probably, or definitely related to treatment. | From the start of treatment until 30 days after the end of treatment, up to approximately 14 months |
