SRK-439 Selectively Inhibits Myostatin to Promote Healthy Body Composition During Metformin Therapy (OBESITY WEEK 2024) - "Selectively inhibiting myostatin in combination with metformin administration increases lean mass and reduces fat mass in DIO mice. This supports the use of SRK-439 to promote healthy body composition during treatment for obesity and type 2 diabetes."

The Antimyostatin Antibody SRK-439 Promotes Healthy Body Composition in Combination with GLP-1RAs in a Mouse Model of Obesity (ADA 2024) - "Mice that received sema + SRK-439 had 18.0% body fat, compared to 28.7% in the sema + IgG group (p<0.05) and circulating leptin was lower in the sema + SRK-439 group when compared to the sema + IgG group (21.7 vs 37.9 ng/mL, p<0.01). These results demonstrate that SRK-439 maintains a healthy body composition during GLP-1RA-induced weight loss."

Scholar Rock Presents New Preclinical Data Demonstrating Potential Benefit of SRK-439 for Healthy Weight Loss Management (Businesswire) - "Scholar Rock...today announced new preclinical data showing the potential of SRK-439 to preserve lean mass and improve metabolic health as part of healthy weight loss. These data showed that SRK-439 maintained lean mass and improved fat mass loss when used in combination with a GLP-1 receptor agonist (GLP-1 RA; in separate experiments with semaglutide and liraglutide) in diet-induced obesity (DIO) mice. SRK-439 treatment also led to incremental lowering of fasting glucose beyond the levels seen with semaglutide alone. Detailed results were presented by Melissa Fulham, PhD, of Scholar Rock, at the Keystone Symposia’s Obesity: Causes and Consequences meeting in Vancouver, BC, Canada on February 5."

Scholar Rock Reports Third Quarter 2023 Financial Results and Highlights Business Progress (Businesswire) - "Plans to initiate a Phase 2 proof-of-concept trial with apitegromab in combination with a GLP-1 receptor agonist (GLP-1 RA) in obesity in 2024. As part of the Company’s strategy to advance the development of SRK-439, it plans to initiate a Phase 2 proof-of-concept trial with apitegromab in combination with a GLP-1 RA in 2024, subject to IND clearance. Data from the clinical trial are expected in mid-2025 and will be used to inform further clinical development of SRK-439. The Company plans to file an IND for SRK-439 for the treatment of obesity in 2025."
