Clinical Trial Summary

This multicenter, single-arm, open-label study will evaluate the long-term safety and efficacy of satralizumab in participants with neuromyelitis optica spectrum disorder (NMOSD) who completed open-label extension (OLE) period of studies BN40898 and BN40900. Participants will receive satralizumab as monotherapy or in combination with one of the following background immunosuppressive treatments: azathioprine (AZA), mycophenolate mofetil (MMF), or oral corticosteroids.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 119
• Est. completion date: May 28, 2024
• Est. primary completion date: May 28, 2024
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Participants aged less than 18 years at the time of informed consent for Study BN40898 can continue treatment with a combination of oral corticosteroids and either AZA or MMF

• Participated in Study BN40898 or Study BN40900 with satralizumab in NMOSD, are on ongoing satralizumab treatment and were anti-aquaporin-4 IgG antibody (AQP4-IgG) seropositive at screening in these studies. Participants with NMOSD who were AQP4-IgG seronegative at screening in Study BN40898 or Study BN40900 can be enrolled if the investigator considers the continued treatment with satralizumab to be beneficial for the participant

• For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use adequate contraception during the treatment period and for 3 months after the final dose of satralizumab.

Exclusion Criteria:

• Pregnant or breastfeeding, or intending to become pregnant during the study or within 3 months after the final dose of study drug. Women of childbearing potential must have a negative urine pregnancy test result on the baseline visit prior to initiation of study drug

• Evidence of any serious uncontrolled concomitant diseases that may preclude participation including nervous system disease, cardiovascular disease, hematologic/hematopoiesis disease, respiratory disease, muscular disease, endocrine disease, renal/urologic disease, digestive system disease, congenital or acquired severe immunodeficiency

• Known active infection that requires delaying the next satralizumab dose at the time of enrollment

• NMOSD relapse at the time of enrollment

• Laboratory abnormalities at the last assessment in Study BN40898 or Study BN40900 that preclude re-treatment with satralizumab
