Interventions
In Part 1, study drug will be administered after all other study-related procedures have been performed at a site visit at Weeks 0, 2, 4, and every 4 weeks (Q4W) thereafter. Participants will receive satralizumab according to body weight. 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. In Part 2, participants will be asked to choose from one of the following options: Option 1: continue on randomized, double-blind study drug; Option 2: start open-label satralizumab based on body weight; Option 3: stop study treatment and continue follow-up assessments.
Satralizumab placebo prefilled syringe (PFS) is identical in composition to satralizumab PFS, but does not contain the satralizumab active ingredient and will be identical in appearance and packaging to satralizumab. A PFS (assembled with an needle safety device \[NSD\] and extended finger flange) filled with 0.5 milliliters (mL) of solution, corresponding to 60 milligrams (mg) satralizumab, may be used in Part 2 once it becomes available at the study site.
