Boston, Suzhou & Shanghai – October 25, 2025 –SanegeneBio, a clinical-stage biotechnology focused on developing best-in-class RNAi medicines for obesity, cardiometabolic, and autoimmune diseases, today announced its participation at the American Society of Nephrology (ASN) Kidney Week 2025, November 5-9 in Houston, TX, USA. Safety and pharmacodynamic data from two Phase I studies of SGB-9768, an investigational RNAi therapeutic targeting C3, conducted at New Zealand Clinical Research and Huashan Hospital of Fudan University in China, will be shared in a poster presentation.
IgAN (IgA Nephropathy) is the most common primary glomerular disease in China, with an estimated 4 million patients, predominantly affecting young and middle-aged adults. IgAN is the leading cause of end-stage renal disease (ESRD) in this demographic in China. Studies show that approximately 50% of IgAN patients with persistent proteinuria progress to ESRD within 10-20 years after diagnosis, requiring dialysis or kidney transplantation. C3G (C3 Glomerulopathy) is a rare kidney disease with a global incidence of 1-2 per million people per year, primarily affecting young adults. Approximately 50% of patients progress to ESRD within 10 years, requiring dialysis or kidney transplantation; post-transplantation, the disease recurs in 50%-70% of patients, making its clinical management extremely challenging.
Despite their differing incidence rates, both IgAN and C3G are closely linked to complement activation. They share the severe challenges of rapid progression and limited treatment options, significantly threatening patient survival and quality of life. SGB-9768 is designed to inhibit complement activation, offering a potential new treatment option for complement-mediated kidney diseases. Phase I data indicate that SGB-9768 has demonstrated a favorable safety profile and greater durability. Furthermore, it demonstrated robust, dose-dependent, and sustained reduction in C3 levels, showing superior C3 gene silencing potency and durability compared to prior C3 RNAi candidates.
Kidney Week, organized by the American Society of Nephrology (ASN), is the world’s premier nephrology meeting. It attracts over 12,000 nephrology professionals from across the globe, provides a dynamic platform for participants to exchange knowledge, learn the latest scientific and medical advances, and engage in thought-provoking discussions with leading experts. The conference serves as a vital platform dedicated to driving innovation in the diagnosis and treatment of kidney disease worldwide.

About SGB-9768
SGB-9768 is a GalNAc-conjugated experimental RNAi-based medicine designed to silence C3 mRNA in hepatocytes, thereby inhibiting complement activation. It is a potential treatment for various complement-mediated kidney diseases, including IgAN, C3G, and IC-MPGN. It has demonstrated potent, sustained reduction in C3 levels following a single subcutaneous dose, with the potential for infrequent dosing and long-term efficacy. With a favorable safety profile and greater durability than comparator molecules, SGB-9768 may become a best-in-class RNAi therapeutic for complement-mediated diseases.
