NCT06904729 | RECRUITING | Lupus Nephritis

Chimeric Antigen Receptors T Cells for Refractory/Recurrent Lupus Nephritis in Children
Sponsor:

Guangzhou Women and Children's Medical Center

Brief Summary:

The goal of this prospective, open, single-arm clinical trial was to evaluate the safety and potential efficacy of CAR T cell therapy in children with refractory/recurrent lupus nephritis. The persistence and cell phenotype of CAR-T cells in vivo and CAR-T treatment-related inflammatory factors were evaluated after treatment. To explore new therapeutic methods, in order to reduce the side effects of traditional therapeutic drugs, increase curative effect, and finally make patients obtain long-term survival and improve survival quality.
