Trial Outcomes & Findings for PR3-AAV Resilient Remission or PRRR (NCT NCT05376319)

NCT ID: NCT05376319

Last Updated: 2024-07-31

Results Overview

Complete remission is defined as a Birmingham Vasculitis Activity Score for Wegener's Granulomatosis (BVAS/WG) of 0 without glucocorticoids beyond the prescribed prednisone taper. Seronegativity for ANCA is defined as a negative test for antibodies directed against serine proteinase 3 (i.e., a negative PR3-ANCA assay).

PRIMARY outcome

Timeframe: 6 months

Population: Terminated study due lack of funding. Data was not collected nor analyzed due to lack of funding. Only one subject in each arm reached 6 months. Data was not collected nor analyzed for 1 subject in the Intravenous dose of obinutuzumab and 3 subjects in the Intravenous dose of rituximab.

Complete remission is defined as a Birmingham Vasculitis Activity Score for Wegener's Granulomatosis (BVAS/WG) of 0 without glucocorticoids beyond the prescribed prednisone taper. Seronegativity for ANCA is defined as a negative test for antibodies directed against serine proteinase 3 (i.e., a negative PR3-ANCA assay).
