ACTIVE NOT RECRUITING Phase 1

A Study to Evaluate the Safety and Efficacy of A2B530, a Logic-gated CAR T, in Participants With Solid Tumors That Express CEA and Have Lost HLA-A*02 Expression

NCT05736731 · View on ClinicalTrials.gov ↗

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

What the Registry Record Tells You About NCT05736731

The ClinicalTrials.gov registry entry for NCT05736731 describes a study currently listed as active not recruiting. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 160 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is A2 Biotherapeutics, which has 4 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.

The record links to 10 conditions, with Pancreatic Cancer appearing as the primary indexed condition, and to 2 interventions — of which A2B530 is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.

Geographic footprint matters for practical reasons: NCT05736731 reports 8 study locations spanning 7 distinct geographic areas — top geographies include California, Arizona, Florida. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
