A Seamless Phase 1/2 Study to Evaluate the Safety and Efficacy of A2B395, an Allogeneic Logic-gated Tmod™ CAR T, in Heterozygous HLA-A*02 Adults With Recurrent Unresectable, Locally Advanced, or Metastatic Solid Tumors That Express EGFR and Have Lost HLA-A*02 Expression
A2 Biotherapeutics Inc.
Summary
The goal of this study is to test A2B395, an allogeneic logic-gated Tmod™ CAR T-cell product in subjects with solid tumors including colorectal cancer (CRC), non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), triple-negative breast cancer (TNBC), renal cell carcinoma (RCC) and other solid tumors that express EGFR and have lost HLA-A\*02 expression. The main questions this study aims to answer are: * Phase 1: What is the recommended dose of A2B395 that is safe for patients * Phase 2: Does the recommended dose of A2B395 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 in BASECAMP-1 (NCT04981119) * Preconditioning lymphodepletion (PCLD) regimen * A2B395 Tmod CAR T cells at the assigned dose
Description
This is a seamless phase 1/2, multi-center, open-label study that enrolls adults with recurrent unresectable, locally advanced, or metastatic (considered non-curative) CRC, NSCLC, HNSCC, TNBC, RCC, or other solid tumors with EGFR expression. Subjects must be germline HLA-A\*02 heterozygous, with tumors that express EGFR and have lost HLA-A\*02 expression. The purpose of Phase 1 of this study is to determine the safety and the optimal dose of A2B395 (after PCLD) in participants with solid tumor disease. The purpose of Phase 2 of this study is to determine the further safety and efficacy (how we…
