生物活性:
Stamulumab (MYO-029) is a recombinant human IgG1λ antibody that binds to myostatin and neutralizes its activity by preventing binding to its endogenous high-affinity receptor ActRIIB. Stamulumab leads to muscle fiber hypertrophy and not hyperplasia in SCID mice. Stamulumab has the potential for Becker muscular dystrophy (BMD), facioscapulohumeral dystrophy (FSHD), and limb-girdle muscular dystrophy (LGMD) research.
体内研究:
Stamulumab (MYO-029; 腹腔给药; 1-10 mg/kg/周; 持续 12 周) 在 SCID 小鼠体内以浓度依赖性方式增加骨骼肌质量。Stamulumab 导致肌纤维肥大而不是增生。Stamulumab (静脉注射; 1, 5, 20, 100 mg/kg/周; 持续 4 周) 在 C57/SCID 小鼠中的中心清除率 (CL) 为 0.25 mL/h/kg.Pharmacokinetic Parameters of Stamulumab (MYO-029).C57/SCID mice IV (1-100 mg/kg/week for 4 weeks) Sprague Dawley rats (2-50 mg/kg; single injection) Cynomolgus monkeys (10-100 mg/kg/week for 5 or 39 weeks)
