Apellis Files Empaveli sNDA in Rare Kidney Diseases
FDA has accepted for priority review an Apellis Pharmaceuticals supplemental NDA for Empaveli (pegcetacoplan) for C3 glomerulopathy (C3G) and primary immune complex membranoproliferative glomerulonephritis (IC-MPGN), which are severe and rare kidney diseases. The agency has set a user fee review action target date of 7/28. “Empaveli demonstrated clinically meaningful benefits across all three key markers of disease — unprecedented proteinuria reductions, stabilization of kidney function, and substantial clearance of C3c staining,” a company release says.
C3G and primary IC-MPGN are rare and debilitating kidney diseases that can lead to kidney failure, according to Apellis. Excessive C3c deposits are a key marker of disease activity, which can lead to kidney inflammation, damage, and failure.
The submission is based on data from the company’s Phase 3 VALIANT study, which met its primary endpoint of demonstrating a statistically significant 68% proteinuria reduction in Empaveli-treated patients compared to placebo, according to the company. Also, Empaveli-treated patients achieved stabilization of kidney function, and a substantial proportion of Empaveli-treated patients achieved a reduction in C3c staining intensity, it says.
