This is a Phase 1, multicenter, open-label study of DISP-10, a combination therapy consisting of DV-10 (adenovirus) and idecabtagene vicleucel (ide-cel, BCMA-directed chimeric antigen receptor \[CAR\] T), in adult participants with advanced gastrointestinal (GI) cancers. The study will consist of 2 parts: dose-escalation (Part 1) and dose-expansion (Part 2). Part 1 of the study will evaluate the safety and tolerability of increasing dose levels of DISP-10 to establish the recommended dose for expansion (RDE); Part 2 will evaluate the safety and efficacy of DISP-10 in participants treated at the RDE.
Key Inclusion Criteria: 1. Histologically confirmed advanced or metastatic esophageal, gastroesophageal junction, gastric adenocarcinoma, or colorectal adenocarcinoma 2.

Aged ≥18 years at time of signing informed consent 5. Adequate organ function Key Exclusion Criteria: 1. Previous solid organ or hematopoietic cell transplant 2. Evidence of rapid disease progression, defined as radiographic or clinical progression…
Participants will undergo leukapheresis to isolate peripheral blood mononuclear cells (PBMCs) to produce ide-cel. During ide-cel production, participants may receive bridging therapy for disease control per Investigator discretion. DV-10 administration will be followed by lymphodepleting chemotherapy (fludarabine and cyclophosphamide) and subsequent ide-cel administration.
