Participants with measurable disease and with evaluable disease as defined by RECIST v1.1 will be enrolled on this study.

AgenT-797 is an investigational product, composed of allogeneic human unmodified iNKT cells, isolated from mononuclear cell aphaeresis units from healthy donors

AgenT-797

Botensilimab is a novel, human, Fc-engineered IgG1 anti-CTLA-4 antibody

Botensilimab

Botensilimab is supplied as a sterile, single-use solution for IV administration

Balstilimab

Ramucirumab is a fully human anti-VEGFR2 monoclonal IgG1 antibody (IgG1) that binds with high affinity to the extracellular domain of VEGFR2. Ramucirumab is a part of standard of care treatment for advanced gastric cancer or GEJ adenocarcinoma, after prior treatment with fluoropyrimidine- or platinum-containing chemotherarapy.

Paclitaxel is widely used across multiple cancer types and is a part of standard of care treatment for advanced EG adenocarcinoma after prior treatment with fluoropyrimidine- or platinum-containing chemotherarapy.

Participants will receive study treatment with agenT-797, botensilimab, balstilimab, ramucirumab, and paclitaxel. When participants start each agent will depend on how their disease is affecting them.

A Study of agenT-797 in Combination With Botensilimab, Balstilimab, Ramucirumab, and Paclitaxel for People With Esophageal, Gastric, or Gastro-esophageal Junction Cancer

A Phase II Study of agenT-797 (Invariant Natural Killer T Cells), Botensilimab, a Novel Fc-enhanced CTLA-4 Inhibitor, Plus Balstilimab (Anti-PD-1) With Ramucirumab and Paclitaxel for Patients With Previously Treated, Advanced Esophageal, Gastric, or Gastro-esophageal Junction Adenocarcinoma
