| Item 8.01 | Other Events. |
On August 8, 2024, Apellis Pharmaceuticals, Inc. (“Apellis”) and Sobi® announced positive topline results from the Phase 3 VALIANT study investigating systemic pegcetacoplan in patients with C3 glomerulopathy (C3G) or primary immune complex membranoproliferative glomerulonephritis (IC-MPGN), which are rare kidney diseases with no approved treatments.
The study met the primary endpoint, demonstrating a statistically significant and clinically meaningful 68% (p<0.0001) proteinuria reduction (log-transformed ratio of urine protein-to-creatinine ratio) in C3G and IC-MPGN patients treated with pegcetacoplan compared to placebo, both in addition to background therapy, at Week 26. Results were consistent across all subgroups, including C3G and IC-MPGN, adolescent and adult patients, and native and post-transplant kidneys.
Pegcetacoplan also demonstrated statistical significance on the key secondary endpoints of composite renal endpoint, which combines proteinuria reduction and estimated glomerular filtration rate (eGFR) stabilization, and proteinuria reduction of at least 50 percent compared to baseline, as well as nominal significance on the histological endpoint of reduction in C3c staining on kidney biopsy and stabilization of kidney function as measured by eGFR compared to placebo.
In the VALIANT study, pegcetacoplan demonstrated favorable safety and tolerability results, consistent with its established profile. Rates of adverse events (AEs), serious AEs, and AEs leading to study drug discontinuation were similar between the pegcetacoplan and placebo groups. There were no cases of meningitis or serious infections attributed to encapsulated bacteria.
All patients who have already completed the VALIANT study have now enrolled into the VALE long-term extension study.
Apellis plans to submit a supplemental new drug application to the U.S. Food and Drug Administration in early 2025, and Sobi plans to submit a marketing application with the European Medicines Agency in 2025. Detailed data will be presented at an upcoming medical congress.
