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.

Short-Course Chemoradiotherapy Followed by Chemotherapy for the Treatment of Resectable Gastric Adenocarcinoma

This phase Ib trial investigates the side effects and how well a shorter course of chemotherapy and radiation treatment (chemoradiotherapy) for 2 weeks instead of 5 weeks followed by standard chemotherapy works in treating patients with gastric cancer who are scheduled to have treatment and then surgery to remove the tumor. Chemotherapy drugs, such as capecitabine and fluorouracil, 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. Radiation therapy uses high energy sources to kill tumor cells and shrink tumors. Giving short-course chemo-radiotherapy before chemotherapy and surgery may help to control the disease.

Early Recovery After Surgery Protocol in Improving Quality of Life in Participants With Stage 0-IIIC Gastric Cancer Undergoing Surgery

This phase II trial studies how well an early recovery after surgery protocol works in enhancing quality of life in participants with stage 0-IIIC gastric cancer undergoing surgery. The early recovery after surgery protocol may decrease pain and nausea, promote bowl function, decrease the number of days hospitalized, and improve a participant's ability to function normally after surgery.
