Slow-tapering glucocorticoids+Inebilizumab arm: A 300 mg intravenous infusion of inebilizumab will be administered on Day 1 and Day 15, followed by 300 mg infusions every 26 weeks thereafter. Prednisone will be initiated at a daily dose of 60 mg as concomitant therapy with inebilizumab. The prednisone dose will be tapered as follows: a reduction of 5 mg every 2 weeks until reaching 20 mg/day(Week 16); thereafter, a reduction of 5 mg every 4 weeks until discontinuation (a total duration of 32 weeks for combined inebilizumab and glucocorticoids therapy).
