About this trial

This is an open label, single-site, dose-escalation study in up to 25 participants with refractory autoimmune diseases of nervous system. This study aims to evaluate the safety and efficacy of the treatment with universal BCMA and CD19 CART.

Anticipated survival of ≥ 12 weeks as judged by the researcher.

Agrees to use double barrier methods, condoms, oral or injectable contraceptives, or intrauterine devices during the study period and for one year after taking the study medication.

Disqualifiers

History of solid organ transplantation.

Malignant tumor within the last two years.
