体内研究
(In Vivo)

Apitegromab (10-300 mg/kg, 静脉注射,一周一次,共 4、7 或 26 周) 在幼年和成年 Sprague Dawley 大鼠以及成年食蟹猴中耐受性良好,未见严重毒性反应[2]

Animal Model: Adult cynomolgus monkeys (32-48 months)[2]
Dosage: 10, 30, 100 mg/kg
Administration: Intravenous bolus (IV bolus), once weekly for 4 weeks
Result: Did not cause treatment-related adverse effects, increased gastrocnemius and biceps brachii mass (5-25%), but did not exhibit dose dependency, and did not lead to significant histopathological changes or cardiac electrophysiological abnormalities.
Animal Model: Sprague Dawley rats: adult group (6-8 weeks) or juvenile group (postnatal day 21)[2]
Dosage: 10, 30, 100, 300 mg/kg
Administration: Intravenous bolus (IV bolus), once weekly for 4 weeks (adult group), 7 weeks (juvenile group) or 26 weeks (adult group)
Result: Increased body weight independently of food intake, enhanced skeletal muscle mass (biceps brachii and gastrocnemius) by 3-32%, and caused minor clinical chemistry changes (mild increase in total protein and globulin), which were mostly reversible (adult group, administration for 4 weeks).
increased muscle mass by 15-33%, induced mild muscle fiber hypertrophy (histological analysis), and caused minor hematological changes without significant toxicity; it did not produce adverse effects on cardiovascular, neurological, or reproductive systems (adult group, administration for 26 weeks).
increased body weight (significant in females) without impacting growth and development, enhanced skeletal muscle mass (biceps brachii and gastrocnemius) by 13-28%, and did not cause neurobehavioral abnormalities (acoustic startle, locomotor activity, Morris water maze); it had no effects on sperm quality or fertility, indicating normal reproductive function (juvenile group).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
