SHENZHEN, CHINA, June 8, 2026 - (ACN Newswire) - China Medical System Holdings Limited ("CMS" or the "Group") is pleased to announce that the preclinical results of its self-developed innovative INHBE-targeting small nucleic acid drug CMS-D008 injection ("CMS-D008"), have been presented in a poster at the American Diabetes Association (ADA) 86th Scientific Sessions (June 5-8, 2026, New Orleans, USA). As the world's largest and most authoritative annual scientific meeting in the fields of diabetes and metabolic diseases, it convened over 12,000 leading clinicians, researchers, and healthcare professionals worldwide to explore cutting-edge advances in diagnostics, therapies, and technologies.About CMS-D008
CMS-D008 is a self-developed novel siRNA therapy administered by subcutaneous injection. It targets and reduces the hepatic expression of the inhibin subunit beta E (INHBE) gene and lowers the level of INHBE-encoded Activin E protein, which blocks Activin E-ALK7 signaling and reduces fat accumulation effectively. It demonstrates the potential for high-quality, long-term weight loss that boosts fat-specific loss while preserving muscle mass. Currently, the Phase I clinical trial of CMS-D008 in healthy subjects is progressing steadily. In the future, it may be developed for the treatment of abdominal obesity and related metabolic diseases.
CMS-D008 has demonstrated encouraging preclinical data. The preclinical research results of CMS-D008 presented at the ADA Scientific Sessions showed that in obese animal models, CMS-D008 efficiently and sustainably suppressed INHBE expression, achieving significant weight loss and fat reduction while sparing muscle mass, with a favorable safety profile, indicating the potential for healthy weight loss. Details are as follows:
Title: CMS-D008 specifically silences INHBE mRNA, delivering fat-selective weight loss in preclinical study
Presentation Number: 3079-LB
Presentation format: Poster
Date/Time: June 7, 2026 01:30 PM - 02:30 PM (Local Time)
Location: Hall D-E
Results:
In a high-fat diet-induced model of humanized INHBE obese mouse (hINHBE DIO mouse), CMS-D008 significantly reduced hepatic INHBE mRNA expression and serum Activin E protein levels, leading to marked decreases in body weight, total body fat, and regional fat mass while preserving lean mass.
In a model of obese cynomolgus macaque, CMS-D008 also significantly reduced hepatic INHBE mRNA expression and plasma Activin E protein levels, and effectively suppressed weight gain induced by a sustained high-fat diet.
The inclusion of these findings at the ADA Scientific Sessions reflects the international academic community's interest in the scientific value and clinical potential of CMS-D008 in the field of obesity/metabolic treatment. CMS-D008 will synergize with CMS-D005, a self-developed, clinical-stage innovative drug (a GLP-1R/GCGR dual agonist), to deliver highly effective weight-loss benefits and long-term maintenance of results, providing patients with a more comprehensive and innovative treatment option.
