Brief Summary:
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 and angiotensin receptor blockers (ARBs). These patients are at high risk for progression of kidney disease, which can result in end-stage renal failure.
