INDICATION and IMPORTANT SAFETY INFORMATION for VOYXACT® (sibeprenlimab‑szsi)

INDICATION

VOYXACT is a prescription medicine used to reduce protein in the urine (proteinuria) in adults with a kidney disease called primary immunoglobulin A nephropathy (IgAN) who are at risk for their disease getting worse. It is not known if VOYXACT is safe and effective in children.

This indication is approved under accelerated approval based on reduction of proteinuria. It has not been established whether VOYXACT slows kidney function decline over the long-term in patients with IgAN. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory clinical trial.
