While current incretin therapies drive significant weight loss, they are increasingly plagued by the loss of lean muscle mass and rapid weight rebound upon discontinuation. Data to be presented at ADA demonstrate that LiCO-saUcp1 directly solves this industry- wide challenge. Utilizing the company’s proprietary Lipid-Conjugated Oligonucleotide( LiCO™) delivery platform, the therapy uses saRNA to target and upregulate the _Ucp1_ gene—a powerful driver of metabolic thermogenesis that has historically been considered" undruggable" by conventional pharmaceuticals. "The obesity market is urgently looking for the ‘next generation’ of therapeutics that go beyond simply suppressing appetite," said Long-Cheng Li, MD, Founder and Chief Executive Officer of Ractigen Therapeutics. "saRNA opens an entirely new frontier in obesity control. By activating the body’s own thermogenic switch, we are changing the fundamental composition of weight loss. Our data show we can deliver profound fat reduction while protecting a patient’s muscle mass and reprogramming their metabolism to prevent the dreaded post-treatment rebound. This is the definition of high-quality weight loss." **Key Highlights from the ADA Late-Breaking Presentation:** ◦ **True "High-Quality" Weight Loss:** In diet-induced obesity (DIO) models, LiCO- saUcp1 slashed fat mass by 45% while completely preserving lean muscle mass. In a direct comparison, standard-of-care semaglutide caused a detrimental 19% loss in lean mass. ◦ **Elimination of the Rebound Effect:** Animals treated with LiCO-saUcp1 maintained their body weight and sustained a 46% fat mass loss for two full months after the drug was withdrawn, sharply contrasting with the rapid weight regain seen upon semaglutide withdrawal. ◦ **Best-in-Class Synergy:** When combined with semaglutide, LiCO-saUcp1 synergistically drove a remarkable 69% reduction in fat mass (compared to 47% with semaglutide alone), without worsening the muscle depletion typically caused by GLP-1s. ◦ **Significant Liver Health Benefits:** The therapy dose-dependently reduced liver triglycerides by up to 79%, demonstrating deep resolution of hepatic steatosis( fatty liver). By proving that RNA activation can safely unlock Ucp1-driven thermogenesis, Ractigen Therapeutics is establishing a highly differentiated therapeutic mechanism that can act as a standalone treatment or as the ideal combination partner for existing incretin therapies. The abstract is available online via the journal _Diabetes®_ website. **Presentation Details at ADA 2026:** ◦ **Title:** Activating the Adipose Thermogenic Switch: A First-in-Class _Ucp1_ saRNA Drives Durable, High-Quality Weight Loss in Diet-Induced Obese Mice ◦ **Poster Number: **3066-LB ◦ **Presenter: **Moorim Kang, PhD, Chief Technology Officer ◦ **Date/Time:** Sunday, June 7, 2026, 12:30 PM – 1:30 PM ◦ **Location:** Ernest N. Morial Convention Center, New Orleans, LA **About RNAa** RNA activation (RNAa) is a clinically validated platform technology developed by Dr. Long-Cheng Li and his team. It utilizes small activating RNAs ( saRNAs) to target gene regulatory domains, robustly activating endogenous gene expression and restoring therapeutic protein levels. This innovative technology holds vast potential for developing disease-modifying therapeutics, particularly against targets where traditional inhibitory methods fall short. **About Ractigen Therapeutics** Ractigen Therapeutics is a clinical-stage biopharmaceutical company innovating next-generation RNA therapeutics, with a primary focus on small activating RNAs (saRNAs) developed through its clinically validated RNA activation( RNAa) technology. Leveraging proprietary delivery platforms such as SCAD™, LiCO™, and GLORY™, Ractigen is advancing a robust pipeline addressing unmet medical needs in oncology, neurological diseases, and genetic disorders. Its versatile technologies also enable the rapid development of RNA-based solutions, including siRNAs, where applicable, to target life-threatening, fast-progressing conditions such as those in the CNS. Committed to scientific excellence and patient-centered innovation, Ractigen strives to transform healthcare through the power of RNA therapeutics.
