ANCA-associated Vasculitis (AAV)

Brief summary

Proportion of subjects achieving disease remission at week 26 based on PVAS., Proportion of subjects with sustained remission at week 52 based on PVAS. Remission: PVAS score of 0 with prednisone-equivalent dose ≤0.2 mg/kg/day (max dosage 10 mg/day) within past 4 weeks. Or PVAS score of 0 for at least 4 weeks, provided the last PVAS is within the prior 8 weeks, irrespective of glucocorticoid dose., Sustained remission: PVAS remission at week 26 & week 52, without relapses between the 2 time points.
