Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the effect of cemdisiran on proteinuria in adults with immunoglobulin A nephropathy (IgAN), who excrete \>1 gram (gm) of protein per day despite standard of care, which includes treatment with angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARB). These participants are at high risk for progression of kidney disease, which can result in end-stage renal failure.
