Group Intervention Description Placebo Placebo - B001 injection B001 -
- Primary Outcome Measures
Name Time Method Time to first NMOSD Attack During RCP Approximately 48 weeks The NMOSD attack is defined as the presence of new or worsening symptom(s) related to NMOSD.
- Secondary Outcome Measures
Name Time Method Change in Opticospinal Impairment Scale (OSIS) Approximately 48 weeks Change in OSIS
Annualized relapse rate (ARR) Approximately 3 years Annualized attack rate is defined as total number of attacks divided by total person years.
Change in Expanded Disability Status Scale (EDSS) Score Approximately 48 weeks EDSS and its associated functional system (FS) score provide a system for quantifying disability and monitoring changes in the level of disability over time. EDSS consists of 7 FS (visual FS, brainstem FS, pyramidal FS, cerebellar FS, sensory FS, bowel and bladder FS, and cerebral FS) which are used to derive EDSS score ranging from 0 (normal neurological exam) to 10 (death from MS).
Change in Vision Acuity/ Low contrast visual acuity (VA/LCVA) Approximately 48 weeks Change in VA/LCVA
Incidence of Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) Approximately 3 years An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse event is any AE that resulted in death, life threatening, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, is a congenital anomaly/birth defect in offspring of a study participant, is an important medical event that may jeopardize the participant or may require medical intervention.
