简要总结

The main objective is to explore the efficacy and safety of Telitacicept in the treatment of refractory/recurrent anti-NMDAR and anti-LGI1 encephalitis.

Through this prospective, single-center, open-label clinical trial, we aim to investigate the effectiveness and safety of Telitacicept in refractory/recurrent anti-NMDAR and anti-LGI1 encephalitis by add-on therapy of Telitacicept combined with traditional treatment.

研究组 & 干预措施

Taitacept treatment group

Experimental

Telitacicept will be subcutaneously injected at a dose of 240mg per week, lasting for at least 24 weeks.

干预措施: Taitacept (Drug)

结局指标

主要结局

the change of mRS score

时间窗: from baseline at week 24

Refractory encephalitis: rate of patients with mRS score \<2 or mRS score improvement of ≥2 points from baseline at week 24; Recurrent encephalitis: proportion of patients with no recurrence and \[mRS score \<2 or mRS score improvement of ≥2 points from baseline at week 24. mRS score vary from 0-6 score and higher scores mean a worse outcome.
