Open Label Two-Arm Study to Evaluate Rilzabrutinib in IgG4-Related Disease Patients
September 6, 2023 updated by: Principia Biopharma, a Sanofi Company
An Open Label, Two-Arm Study to Evaluate the Effect of Rilzabrutinib (PRN1008/SAR444671) on Safety and Disease Activity in Patients With IgG4-Related Disease
This is a Phase 2a, multi-center, open-label, two-arm study of approximately 25 patients with active IgG4-related disease (IgG4-RD).
The two arms include (1) Experimental: rilzabrutinib with glucocorticoids and (2) Active Comparator: glucocorticoids only.
