Losartan and Nivolumab in Combination with Combination Chemotherapy and SBRT in Treating Patients with Localized Pancreatic Cancer
- Histologically confirmed localized pancreatic adenocarcinoma; borderline/potentially resectable or locally advanced. * Borderline resectable is defined by the National Comprehensive Cancer Network (NCCN) as tumors with venous involvement of the superior mesenteric vein (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 superior mesenteric artery (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 computed tomography [CT]) of involvement of the celiac axis or SMA, no evidence (CT or magnetic resonance imaging [MRI]) of occlusion of the SMV or superior mesenteric-portal vein (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.
- Eastern Cooperative Oncology Group (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 at least five minutes apart. Blood pressure (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.
- Absolute neutrophil count >= 1,500/mm^3.
- Platelets >= 100,000/mm^3.
- Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) if no biliary stenting has been done OR 2.0 x ULN if patient is s/p biliary stenting OR two down trending values.
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional ULN OR two down trending values.
- Potassium (not hemolyzed) < 5 mmol/L.
- Creatinine =< 1.5 mg/ dL OR creatinine clearance >= 30 mL/min (as estimated by Cockcroft Gault equation).

- Women of childbearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [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 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, i.e., 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 at least 7 days prior to initiation of treatment.
- 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. Patients must be on ACE/ARB therapy for >= 1 month prior to entering the study on Arm 4.

Inhaled or topical steroids and adrenal replacement doses > 15 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease. Subjects are permitted to use topical, ocular, intra-articular, intranasal, and inhalational corticosteroids (with minimal systemic absorption). Physiologic replacement doses of systemic corticosteroids are permitted, even if > 10 mg/day prednisone equivalents.
