- Incidence treatment-emergent adverse events and adverse event of special interest [ Time Frame: Up to 60 weeks ]
- Composite Glucocorticoid Toxicity Index (C-GTI) comprising the Aggregate Improvement Score (AIS) and the Cumulative Worsening Score (CWS) [ Time Frame: Up to 52 weeks ]
- Prednisone dose reduction (average monthly dose) [ Time Frame: Up to 52 weeks ]
- Proportion of participants who discontinue corticosteroids [ Time Frame: Up to 52 weeks ]
- Total improvement score (TIS) [ Time Frame: Up to 52 weeks ]measured on a [0,100] scale. Higher scores represent improvement; zero indicates no improvement or worsening (from baseline).
