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

The goal of this clinical trial is to learn whether the Ad5.F35-hGCC-PADRE vaccine is safe and can stimulate an immune response against gastrointestinal (GI) cancers in patients with pancreatic, colorectal, esophageal, gastric, or small bowel adenocarcinomas who have completed surgical resection and standard adjuvant therapy. An additional goal is to evaluate whether the vaccine may help eliminate minimal residual disease (MRD) in ctDNA-positive colon cancer patients. The main questions it aims to answer are: Is the Ad5.F35-hGCC-PADRE vaccine safe and tolerable at different dose levels? Does the vaccine induce GCC-specific T-cell immune responses in patients with GI malignancies? In ctDNA-positive colon cancer patients, can the vaccine promote ctDNA clearance as a marker of MRD elimination? The investigators will compare immune responses across different vaccine dose levels (10¹¹, 10¹², and 5 × 10¹² virus particles) to determine the optimal dose. Participants will: Receive the Ad5.F35-hGCC-PADRE vaccine by intramuscular injection. Be assigned to one of three dose levels during the dose-finding phase or receive a prespecified dose in the dose-expansion cohort. Undergo safety assessments, including monitoring for adverse events, injection-site reactions, and laboratory test abnormalities. Have blood samples collected to evaluate GCC-specific T-cell immune responses. For ctDNA-positive colon cancer patients, undergo ctDNA testing to assess clearance of minimal residual disease.

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 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.
