Apellis to Present Phase 3 VALIANT Study on Pegcetacoplan at ASN Kidney Week

Apellis Pharmaceuticals, Inc., a biopharmaceutical company listed on Nasdaq (APLS), has made significant strides in the treatment of rare kidney diseases. The company recently announced that the abstract of its Phase 3 VALIANT study focusing on pegcetacoplan for patients with C3 glomerulopathy (C3G) and primary immune complex membranoproliferative glomerulonephritis (IC-MPGN) has been accepted for an oral presentation at the American Society of Nephrology (ASN) Kidney Week. This prestigious recognition highlights the importance of their findings and the impact of their work in the field.

The VALIANT study is a large-scale, randomized, placebo-controlled, double-blind trial conducted across multiple centers. It evaluates the efficacy and safety of pegcetacoplan in both adolescent and adult patients who have native or post-transplant kidneys affected by C3G or primary IC-MPGN. Participants in the study were administered 1080 mg of pegcetacoplan or a placebo twice weekly over a period of 26 weeks. After this phase, all participants entered a 26-week open-label phase where they received pegcetacoplan. The primary endpoint of the study was the change in the urine protein-to-creatinine ratio (uPCR) at Week 26 compared to baseline.

C3G and primary IC-MPGN are rare kidney diseases characterized by excessive deposits of C3c, leading to inflammation and potential kidney failure. These debilitating conditions have no current treatments that address their root cause. Patients often face a grim prognosis, with approximately half experiencing kidney failure within five to ten years of diagnosis, necessitating a kidney transplant or lifelong dialysis. Moreover, 90% of patients who receive a transplant will likely see a recurrence of the disease. These conditions affect around 5,000 individuals in the United States and up to 8,000 in Europe.

Pegcetacoplan, the drug under investigation in the VALIANT study, is designed to modulate the complement system, a part of the immune system that, when overactive, can contribute to various serious diseases. Already approved under the name EMPAVELI®/Aspaveli® for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) in several regions, pegcetacoplan is being further studied for its potential in treating other rare diseases in both hematology and nephrology.

Apellis Pharmaceuticals aims to revolutionize the treatment landscape for patients with challenging and rare diseases. With their innovative approach targeting the complement system, they have introduced new therapeutic options after a long period without significant advancements in the field. Their dedication is reflected in their ongoing efforts to explore the full potential of pegcetacoplan across various conditions.

The company will discuss the detailed results of the VALIANT study in a webinar scheduled for October 26, 2024. Key speakers at the webinar include Dr. Carla Nester, who will present the High Impact Clinical Trial results, as well as Dr. Jean E. Robillard and Dr. Cedric Francois. The live session will provide valuable insights into the study findings and their implications for patients with C3G and IC-MPGN.

Additionally, two more abstracts related to pegcetacoplan will be presented as posters at the ASN Kidney Week. One focuses on the drug's effects in post-transplant recurrent C3G or IC-MPGN, presented by Dr. Anuja Java. The other examines the long-term safety and efficacy of pegcetacoplan in patients with these conditions, presented by Dr. Carla Nester.

Overall, Apellis Pharmaceuticals continues to push the boundaries in biopharmaceutical research, bringing hope to patients suffering from rare and debilitating diseases. Their dedication to science and compassionate approach towards patient care underscore their commitment to making a significant impact in the medical field.
