This indication is approved under accelerated approval based on a reduction of proteinuria [see Clinical Studies (14.1)] . It has not been established whether VANRAFIA slows kidney function decline in patients with IgAN. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory clinical trial.
