Advancing treatment of spinal muscular atrophy through inhibition of the myostatin signaling pathway. (PubMed, Expert Rev Neurother) - "Treatments that inhibit myostatin signaling represent a potential complementary pathway for direct muscle enhancement. In the evolving SMA treatment landscape, understanding how muscle-targeted treatment can be incorporated into clinical practice will facilitate individualized treatment decisions and identify outcomes that best encapsulate maintenance or improvement of motor function across the phenotypic spectrum of SMA."

Taldefgrobep/Myostatin Complex Inhibits TGF-ß Ligand Signaling Reducing Lipid Storage in Adipocytes (OBESITY WEEK 2025) - "SMAD2/3 signaling through the activin receptors by TGF-ß superfamily proteins in adipocytes rewires intracellular metabolism to promote fat storage. Inhibition of this pathway with taldefgrobep through the taldefgrobep/myostatin complex, reverts the metabolic changes and leads to reduced lipid storage, and in preclinical models and clinical studies, an improvement in body composition. Our data support the role of activin receptor mediated signaling in regulating adipose homeostasis, and inhibiting SMAD2/3 signaling with molecules like taldefgrobep leads to decreased adipose mass."

Taldefgrobep Alfa Improved Body Composition as Mono or in Combination With Semaglutide in DIO Model (OBESITY WEEK 2024) - "Taldefgrobep, as monotherapy or in combination with a GLP-1R agonist, demonstrated a significant reduction in adipose tissue while increasing lean mass despite GLP1 induced muscle loss supporting the continued development in individuals living with overweight and obesity."

Taldefgrobep Alfa Reduces Lipids and Increases Mitochondrial Content in Adipocytes (OBESITY WEEK 2024) - "Taldefgrobep/myostatin complexes directly affect activin II receptor signaling cascades in adipose tissue to reduce fat storage. SMAD signaling negatively regulates lipolysis in adipose tissue and pharmacological inhibition potentiates lipolysis, leading to reduced adipocyte size. Recently, antibodies against the adipose-specific activin-like kinase 7 were shown to significantly reduce adipose tissue and increase insulin sensitivity."

Insulin and leptin levels were consistently lower in taldefgrobep-treated mice compared to untreated. There was no difference in food intake over time across the taldefgrobep and untreated mice....A Phase 2 obesity study with taldefgrobep is planned for 2024."
