Study Summary

The goal of this study is to test A2B530,an autologous logic-gated Tmod™ CAR T-cell product in subjects with solid tumors including colorectal cancer (CRC), pancreatic cancer (PANC), non-small cell lung cancer (NSCLC), and other solid tumors that express CEA and have lost HLA-A\*02 expression. The main questions this study aims to answer are: * Phase 1: What is the maximum or recommended dose of A2B530 that is safe for patients * Phase 2: Does the recommended dose of A2B530 kill the solid tumor cells and protect the patient's healthy cells Participants will be required to perform study procedures and assessments, and will also receive the following study treatments: * Enrollment and Apheresis in BASECAMP-1 (NCT04981119) * Preconditioning Lymphodepletion (PCLD) Regimen * A2B530 Tmod CAR T cells at the assigned dose

Primary Outcome

Adverse Events and toxicity will be evaluated according to the Cancer Therapy Evaluation Program Common Terminology Criteria for Adverse Events version 5.0 (or current version). Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) events will be graded according to the criteria described in the current protocol.
