A Study to Evaluate the Safety and Efficacy of A2B694, a Logic-gated CAR T, in Participants with Solid Tumors That Express MSLN and Have Lost HLA-A*02 Expression

Description

The goal of this study is to test A2B694, 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), ovarian cancer (OVCA), mesothelioma (MESO), and other solid tumors that express MSLN and have lost HLA-A\*02 expression. The main questions this study aims to answer are: Phase 1: What is the recommended dose of A2B694 that is safe for patients Phase 2: Does the recommended dose of A2B694 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 A2B694 Tmod CAR T cells at the assigned dose

Conditions

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. Has disease that is suitable for local therapy or able to receive standard of care therapy that is therapeutic and not palliative
  • 2. Prior allogeneic stem cell transplant
  • 3. Prior solid organ transplant
  • 4. MESO with pleural involvement extending into the peritoneum
  • 5. Cancer therapy within 3 weeks or 3 half lives of A2B694 infusion
  • 6. Radiotherapy within 28 days of A2B694 infusion
  • 7. Unstable angina, arrhythmia, myocardial infarction, or any other significant cardiac disease within the last 6 months
