NCT05271409

Brief Summary

The main objective of this study is to evaluate the efficacy of satralizumab compared with placebo based on time from randomization to the first occurrence of an adjudicated MOGAD relapse in the double-blind (DB) treatment period. Participants who experience an adjudicated relapse or complete the DB period can enter open-label extension (OLE) period. After the primary clinical cutoff date (CCOD), additional adolescent participants may be enrolled directly into the OLE period.

    Up to approximately 44 months

Secondary Outcomes (4)

  • Annualized Rate of Adjudicated MOGAD Relapses

    Up to approximately 44 months

  • Annualized Rate of Active Lesions on Magnetic Resonance Imaging (MRI) of the Neuroaxis

    Up to approximately 44 months

Study Arms (2)

Satralizumab

EXPERIMENTAL

In the DB treatment period, participants will receive satralizumab at Weeks 0, 2, 4 (loading doses) and maintenance doses every 4 weeks (Q4W) thereafter. In the OLE period, all participants will receive open-label treatment with satralizumab. Additional adolescent participants will be directly enrolled in the OLE period to receive satralizumab.

Drug: Satralizumab

Placebo

PLACEBO COMPARATOR

In the DB treatment period, participants will receive satralizumab matching placebo at Weeks 0, 2, 4 (loading doses) and maintenance doses Q4W thereafter. In the OLE period, all participants will receive open label treatment with satralizumab.

Other: Placebo

Interventions

Study drug will be administered by subcutaneous (SC) injection in the abdominal or femoral region after all other study-related procedures have been performed at a site visit.
