Investigational New Drug (IND) application planned in 2025 for LX9851, a first-in-class, potent, selective, orally bioavailable molecule, as an anti-obesity agent

Data from Lexicon's Obesity Week presentations summarize the preclinical efficacy and mechanism of action of LX9851

THE WOODLANDS, Texas, Nov. 04, 2024 (GLOBE NEWSWIRE) -- Lexicon Pharmaceuticals, Inc. (NASDAQ:LXRX) today announced it will present data from two studies related to LX9851, its investigational compound for obesity and weight loss, at Obesity Week 2024, November 3-5, 2024, at the Henry B. Gonzalez Convention Center in San Antonio, Texas.

Preclinical in vivo efficacy data from the first study showed that treatment with LX9851 resulted in significant reductions in weight, food intake and fat mass in diet-induced obese (DIO) mice. Among other important findings, LX9851 mitigated weight regain following discontinuation of the GLP-1 analogue semaglutide. This study ("First-in-Class ACSL5i LX9851 Enhances and Maintains Semaglutide-Promoted Weight Loss in DIO Mice") investigated the body-weight reduction and weight maintenance effects of Lexicon's first-in-class small molecule ACSL5 inhibitor, as a monotherapy and in combination with semaglutide, in a DIO mouse model. On Day 28, fat and lean body mass were measured by DEXA (OsteoSys body analyzer). All treatments with LX9851 resulted in a reduction in fat mass compared to vehicle control. The greatest weight reduction with no significant effect on lean body mass was observed when LX9851 was combined with semaglutide. The combination therapy also resulted in additive positive effects on liver steatosis and related study end points.
