About this trial
This is an interventional other trial for Locally Advanced Pancreatic Adenocarcinoma focused on measuring pancreatic, cancer, adenocarcinoma, vaccine
Eligibility Criteria
Inclusion Criteria:
Pancreatic adenocarcinoma proven by biopsy or cytology Locally advanced, unresectable disease with absence of distant metastatic disease. The presence of non-regional retroperitoneal or abdominal adenopathy is acceptable for inclusion.
OR
Borderline resectable pancreatic adenocarcinoma (any of the following):
- Tumor abutment or encasement of a short segment of hepatic artery (without evidence of tumor extension to the celiac artery) that is amenable to resection and reconstruction
- Tumor abutment of the superior mesenteric artery involving 180 degrees or less of the circumference of the artery and without encasement
- Impingement or narrowing of the superior mesenteric vein/portal vein or short-segment (< 2 cm) occlusion of the superior mesenteric vein, portal vein, or their confluence with a suitable option for vascular reconstruction
- Eastern Cooperative Oncology Group(ECOG)Performance Status 0 or 1
- Ability to give informed consent and comply with the protocol
- Women of childbearing potential must have a negative pregnancy test and must avoid becoming pregnant while on treatment. Men must avoid fathering a child while on treatment.
- Patients with a history of psychiatric illness must be judged able to understand fully the investigational nature of the study and the risks associated with the therapy.
Exclusion Criteria:
- Age < 18 years
- History of other malignancy in the past 2 years except carcinoma in situ of the cervix or bladder, or non-melanomatous skin cancer
- Previous chemotherapy or radiation therapy for pancreatic cancer or previous radiation therapy to the target field
- Clinically active autoimmune disease or active infection
- History of heart attack (within 90 days) or stroke (within 6 months), or presence of hypertension requiring change in blood pressure medications in the last 4 weeks, hypotension, uncontrolled arrhythmias, heart failure (New York Heart Association (NYHA) Functional Classification ≥ Class 2 in last 6 months), unstable angina or angina occurring during sexual activity.
- Use of "nitrates" or nitroglycerin.
- History of hereditary degenerative retinal disorders including retinitis pigmentosa.
- Chronic systemic corticosteroid use at supra-physiologic doses (prednisone > 10 mg a day or equivalent)
- Use of recreational drugs called "poppers" like amyl nitrite and butyl nitrite.
Laboratory values (performed within 14 days prior to enrollment) as follows:
- Neutrophil count < 1500 cells/µL
- Hemoglobin < 9 gm/dL (patients may be transfused to establish eligibility)
- Platelet count < 100,000 cells/µL
- Significant coagulopathy (INR > 1.5)
- Significant liver or renal dysfunction
- Other medical or psychiatric conditions that in the opinion of the Principal Investigator would preclude safe participation in protocol.

Arms of the Study
Arm 1
Experimental
tadalafil and vaccination
Participants receive a 4-week course of vaccination with telomerase vaccine and GM-CSF by injection, along with a cycle of gemcitabine chemotherapy (IV). This is followed by radiation and gemcitabine given twice weekly then by another dose of vaccine.
