NCT05551598

Brief Summary

This is a multicenter, randomized, double-blind, placebo-controlled Phase Ⅱ study to evaluate the efficacy and safety of Mitoxantrone Hydrochloride Liposome Injection with different doses in participants with neuromyelitis optica spectrum disorder (NMOSD). Participants will be randomly enrolled into three groups: Mitoxantrone Hydrochloride Liposome Injection 8 mg/m\^2 group, Mitoxantrone Hydrochloride Liposome Injection 12 mg/m\^2 group, and Placebo group. The primary outcome measure is time to first protocol-defined relapse.

Outcome Measures

Primary Outcomes (1)

  • Time to First Protocol-defined Relapse

    Time to First Protocol-defined Relapse was defined as time from randomization to first occurrence of relapse. Protocol-defined relapse was occurrence of new or worsening neurological symptoms attributable to neuromyelitis optica spectrum disorder (NMOSD).

    Up to Week 48
