Data support bimagrumab’s novel mechanism to achieve quality weight loss based on decreasing body fat while increasing muscle mass

NEW YORK, June 23, 2023 – Versanis Bio (“Versanis”), a clinical-stage biopharmaceutical company advancing novel therapeutics for obesity and other cardiometabolic diseases, today announced an oral presentation at the upcoming American Diabetes Association 83rd Scientific Sessions, held June 23-26, 2023, in San Diego, California, and online. 

Versanis’s Chief Medical Officer, Kenneth M. Attie, M.D. will present the abstract, titled “Optimized Weight Loss with Bimagrumab: Reduced Fat Mass with Increased Muscle Mass by Appetite-Independent Mechanisms” during an oral abstract session. 

“For many individuals who have lost weight with diet and exercise or incretin therapies, the significant loss of lean mass experienced is undesirable and may prevent durable weight loss maintenance,” said Dr. Attie. “These data underscore that bimagrumab can reduce fat mass while increasing metabolically active lean mass for more sustained, higher-quality weight loss without affecting appetite.”

BELIEVE is a Phase 2b study in non-diabetic patients with overweight or obesity investigating the safety and efficacy of bimagrumab alone and in combination with semaglutide. Eligible patients with a body mass index ≥ 30, or ≥ 27 with one or more obesity-related comorbidities, will receive 48 weeks of treatment to assess safety and tolerability, along with improvement in key obesity measures, including changes in body weight, waist circumference, and body composition. The study has completed enrollment and top-line results are expected in mid-2024.

About Bimagrumab

Bimagrumab is a first-in-class, fully human IgG1/λ monoclonal antibody with picomolar affinity for both activin type II receptors A and B that blocks binding of ligands, including myostatin and activins. Bimagrumab decreases body fat, especially abdominal visceral fat, while at the same time increasing muscle mass. Since initial development, bimagrumab has been administered to more than 1,000 patients for up to 18 months across more than 20 clinical studies. It is now being advanced as a novel treatment for patients living with obesity, with additional indications to follow.
