New treatment option for Solid Tumor
Official title GD2/PSMA Bi-specific CAR-T Cell Therapy
ClinicalTrials.gov ID: NCT05437315
What this study is testing
What is bi-4SCAR GD2/PSMA T cells?
bi-4SCAR GD2/PSMA T cells is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for solid tumor.
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
- The purpose of this clinical trial is to assess the feasibility, safety and efficacy of anti-GD2/PSMA bi-specific CAR-T cell therapy in patients with GD2 and PSMA positive tumor. Another goal of the study is to learn more about the function of the anti-GD2/PSMA bi-specific CAR-T cells and their persistency in patients.
- 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.

You may be able to join if
- Patients with tumors have received standard first-line therapy and have been judged to be non-resectable, metastatic, progressive or recurrent.
