Long-term efficacy of satralizumab in NMOSD patients testing positive for aquaporin-4 antibodies
Two separate earlier clinical trials showed satralizumab to be efficacious in patients with seropositive or seronegative NMOSD, both when administered along with immunosuppressant therapy (known as the SAkuraSky study) and when administered alone (known as the SAkuraStar study). This study assessed the continued efficacy of satralizumab, with or without immunosuppressants, over more than 3.5 years in 103 of the AQP4-antibody seropositive patients from these earlier two studies. The results showed that the efficacy of satralizumab persisted over more than 3.5 years. High proportions of patients remained free from relapse, severe relapse, or worsening disease, with a consistently low annualized relapse rate.
