What this trial studies

This observational study aims to evaluate the effectiveness and safety of inebilizumab during acute attacks of neuromyelitis optica spectrum disorders (NMOSD). It is a multicentric, prospective study involving approximately 50 patients across 10 centers in China. Participants will be compared to those receiving oral immunosuppressants, with a focus on real-world outcomes. The study will include patients who are anti-AQP4-IgG seropositive and experiencing acute symptoms.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with anti-AQP4-IgG seropositive NMOSD in the acute phase.

Not a fit: Patients who are pregnant, lactating, or have severe mental disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into a more effective treatment option for patients experiencing acute NMOSD attacks.

How similar studies have performed: While this approach is observational, similar studies have shown promise in evaluating treatments for NMOSD, suggesting potential for meaningful insights.
