Summary

This is an open-label, non-randomized, multicenter Phase 1/2 trial evaluating a dual CAR-T cell therapy targeting CD146 and HER2 in patients with advanced sarcoma. Participants will receive lymphodepleting chemotherapy with cyclophosphamide and fludarabine, followed by sequential infusion of autologous CD146-specific and HER2-specific CAR-T cells. The Phase 1 portion will employ a dose-escalation design to assess safety and determine the recommended Phase 2 dose, while the Phase 2 expansion will evaluate preliminary efficacy (tumor response and survival outcomes). Approximately 40 patients (children and adults) with relapsed or refractory sarcomas will be enrolled across multiple centers. All participants will be followed for up to 36 months to monitor dose-limiting toxicities, objective response rates, progression-free survival, overall survival, and long-term safety.

Interventions

BIOLOGICAL

CD146/HER2 CAR-T cells

The intervention in this clinical trial involves a novel approach using CD146/HER2 Chimeric Antigen Receptor T (CAR T) cells combined with chemotherapy. The goal is to assess safety and efficacy in patients with specific hematologic malignancies. Treatment Regimen: Patients in the trial will undergo the following regimen: Fludarabine Phosphate (Days -4 to -2): IV administration of fludarabine phosphate over 30 minutes on days -4 to -2. It's part of the preparatory regimen to enhance the body's response to CAR T-cell therapy. Cyclophosphamide (Day -2): IV cyclophosphamide over 60 minutes on day -2. BCMA/GPRC5D Chimeric Antigen Receptor T Cells (Day 0): IV administration of investigational therapy, CD146/HER-2 CAR T cells, over 10-20 minutes on day 0. Additional Doses: Eligible patients responding well to the initial CD146/HER-2 CAR-T cell infusion without unacceptable side effects and sufficient CAR-T cell availability may receive 2 or 3 additional doses.
