SanegeneBio Announces First Patient Dosed in Phase 1 Trial of SGB-7342

BOSTON, SHANGHAI, and SUZHOU – January 13, 2026, SanegeneBio, a clinical-stage biotechnology company developing innovative RNAi therapeutics, announced that the first patient has recently been dosed in a Phase 1 clinical trial of SGB-7342 at the first hospital of Jilin University in China. This randomized, double-blind, placebo controlled, single ascending dose Phase 1 clinical trial is designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of SGB-7342 in overweight and obese patients.

SGB-7342 is an investigational GalNAc-conjugated siRNA medicine for the treatment of obesity targeting Inhibin Beta E (INHBE) messenger RNA (mRNA) in hepatocytes. It incorporates SanegeneBio’s proprietary GalNAc configuration and oligonucleotide chemistry, which has resulted in potentially best-in-class Phase 1 performance for several other recent investigational siRNA medicines. SGB-7342 is designed to silence the INHBE gene through an RNAi mechanism, thereby reducing circulating Activin E levels and inhibiting downstream signaling pathways involved in lipid metabolism and energy expenditure. In preclinical studies, SGB-7342 demonstrated robust INHBE silencing, loss of body weight and fat mass, preservation of lean mass, and a favorable safety and tolerability profile.

Dr. Yuyan Jin, Senior Vice President of Clinical and Nonclinical Development at SanegeneBio, stated:

“The first patient dosed with SGB-7342 marks a significant milestone in its development. Leveraging the RNAi mechanism, it has the potential to achieve selective fat loss while preserving lean muscle, offering a novel, differentiated treatment strategy for obesity. This achievement also represents a solid step forward in SanegeneBio’s strategic commitment to developing innovative therapies for obesity and metabolic diseases. We will advance the subsequent clinical development of SGB-7342, striving to bring this transformative therapy to patients with obesity worldwide.”
