Gemcitabine, Nab-paclitaxel, Durvalumab, and Oleclumab Before Surgery for the Treatment of in Resectable/Borderline Resectable Primary Pancreatic Cancer

This phase II trial studies the effects of gemcitabine, nab-paclitaxel, durvalumab, and oleclumab in treating patients with primary pancreatic cancer that may be able to be removed by surgery (resectable/borderline resectable). Chemotherapy drugs, such as gemcitabine and nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as durvalumab and oleclumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving gemcitabine, nab-paclitaxel, durvalumab, and oleclumab may help control the disease in patients with resectable/borderline resectable primary pancreatic cancer.

A Vaccine (Ad5.F35-hGCC-PADRE) for the Treatment of Gastrointestinal Adenocarcinoma

This is an open-label, dose-finding, Phase 2A/2B study of Ad5.F35-hGCC-PADRE as a vaccine for gastrointestinal (GI) malignancies (pancreatic, colorectal, esophageal, gastric, and small bowel adenocarcinomas) who have received surgical resection and standard adjuvant therapy. In Phase 2A, patients will be given multiple administrations of Ad5.F35-hGCC-PADRE intramuscularly at 1 of 3 dose levels. Treatment-related toxicity and development of immune responses to GCC will be evaluated at Weeks 5, 9, and 13 after the initial vaccination (Week 1). Primary safety endpoints will examine adverse events (AEs), injection-site reactions and clinically-significant changes in safety laboratory tests. Primary efficacy endpoints include the development of GCC-specific T-cell responses at different dose levels (1011, 1012, and 5x1012 virus particles or vp). In Phase 2B Dose Expansion cohort, a group of 20 colon cancer patients who are ctDNA+ by CLIA-certified standard of care assays will receive a single administration of Ad5.F35-hGCC-PADRE vaccine intramuscularly at prespecified dose of 1012 vp. Phase 2b is NOT randomized. Primary safety endpoints will examine AEs, injection-site reactions and clinically significant changes in safety laboratory tests. The primary efficacy endpoints include GCC-specific T-cell responses at 1012 vp in ctDNA+ patients. Additional exploratory endpoint will determine elimination of minimal residual disease (MRD) by ctDNA clearance.

A Study to Determine if the Drug, Pyrvinium Pamoate, is Safe and Tolerable in Patients With Pancreatic Cancer

This phase I trial studies the side effects and best dose of pyrvinium pamoate for the treatment of pancreatic ductal adenocarcinoma that cannot be removed by surgery (resectable). Pyrvinium pamoate may slow down tumor growth and help patients live longer.
