In Vitro	Lomtegovimab 靶向 SARS-CoV-2 S 的 RBD，KD 值为 1.09 nM[2]。 Lomtegovimab 显示中和活性，对 SARS-CoV-2 S D614G, SARS-CoV-2 S B.1.1.7, SARS-CoV-2 BavPat1 (B.1) 的 IC50 值分别为 0.001、0.001、0.010 µg/mL[2]。
In Vivo	Lomtegovimab (40 mg/kg；i.p. 或 i.n.；一次；感染前三天) 保护 hACE2 转导的小鼠免受 SARS-CoV-2 感染[2]。 Animal Model: BALB/c mice (Ad_ACE2-mCherry)[2] Dosage: 40 mg/kg Administration: I.p. or I.n.; once; three days before infection Result: Led to a complete neutralization of infectious SARS-CoV-2 and slightly reduced amounts of viral RNA in the lungs of treated animals.
