Solid Tumor, Adult study: A2B694 vs A2B543
Official title A Study to Evaluate the Safety and Efficacy of Mesothelin-Targeting Logic-gated CAR T, in Participants With Solid Tumors That Express MSLN and Have Lost HLA-A*02 Expression
ClinicalTrials.gov ID: NCT06051695
What this study is testing
What is A2B694?
An investigational autologous CAR T‑cell therapy being studied for solid tumors that express mesothelin. It is designed to target mesothelin on tumor cells while using a logic‑gated system to avoid attacking healthy cells that retain HLA‑A02.
Also referred to as Tmod CAR T-cell Therapy.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study aims to find the safest dose of the treatment and check if it can kill cancer cells while protecting healthy tissue.
- Who it's for
- Adults with solid tumors like lung, colon, or ovarian cancer that express mesothelin and have lost a specific immune marker.
- What's involved
- Participants will have their own immune cells collected, treated in a lab, and then infused back into their body after receiving chemotherapy to lower their immune system.
- Time commitment
- The study involves multiple visits for blood draws, cell collection, and monitoring over several months.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
