pharmacokinetic similarity, safety, and immunogenicity of semaglutide injection and ozempic ® injection in healthy subjects.

Conditions: Type 2 Diabetes

Summary: this study is a randomized, open-label, single-dose, parallel-controlled biosimilar comparison study comparing the pharmacokinetics, safety and immunogenicity of the investigational drug and the active comparator in healthy adult subjects. eligible healthy participants will be screened and randomly assigned to the experimental group and the active comparator group at a ratio of 1:1 , semaglutide injection or ozempic® injection 0.25mg abdominal subcutaneous injection will be given according to their groups. follow-up for 5 weeks after administrtion. studies included a screening period (up to 2 weeks), baseline, administration (single dose), and a follow-up period (5 weeks). the duration of the study will be approximately 7 weeks for a participant.
