Brief Summary:
This is a phase II/III multicenter, randomized, double-blind, placebo-controlled study, to investigate the efficacy and safety of BAT4406F injection in patients with neuromyelitis optica lineage disease (NMOSD) who are positive for aquaporin 4 antibody (AQP4-IgG) .
Detailed Description:
This study was a phase II/III multicenter, randomized, double-blind, placebo-controlled study, which was divided into screening period (4 weeks) , randomized control period (RCP) , and open-label period (Olp)A total of 162 subjects were enrolled during the screening period and randomly assigned 2:1 to either the BAT4406F group or the placebo group after randomization on Day 1 of the RCP, subjects would receive BAT4406F (at a dose of 500mg) or placebo, intravenously, at D 1 and D 182, respectively.
If any of the following conditions occur, subjects can enter OLP from RCP: 1. Subjects who complete the 52-week RCP study without recurrence of NMOSD can enter Olp within 14 days after the end of the RCP study. 2. In the stage of RCP, NMOSD recurred. After rescue therapy, the patients with stable condition could enter OLP within 28 days after diagnosis. Subjects continued to participate in the RCP study if they were not identified by CEC as having a relapse upon examination. 3. When a protocol-defined first relapse event of 35 cases is observed, or when all 162 subjects have completed randomization and 12 months have elapsed since the first dose in the last of these subjects, or when recommended by the Independent Data Monitoring Committee (IDMC) , the RCP study should be stopped for enrolled subjects, and all enrolled subjects at the RCP stage should stop the RCP study within 14 days of entry into OLP, after which subjects will receive BAT4406F injection at the same dose as RCP, at d 1 of OLP. After termination of the RCP study with BAT4406F every 6 months, subjects were given the option of enrolling in the OLP study.
