Phase I Study Comparing SJ04 and Ovidrel Injection Effects in Healthy Chinese Women Ages 20 to 40

What this Trial Is About

This research aims to compare the pharmacokinetics of SJ04, a biosimilar of Ovidrel4, in healthy Chinese female subjects aged 20 to 40 years. The study evaluates how similar the body processes these two recombinant human chorionic gonadotropin injections when given by subcutaneous injection. It is a randomized, open-label, single-dose, two-cycle, double-crossover trial involving healthy women to assess drug similarity and safety. Participants are randomly assigned to two groups one receives SJ04 first followed by Ovidrel4 after a two-week washout period, and the other receives Ovidrel4 first followed by SJ04 after the same interval. Each injection is a single subcutaneous dose of 250 1g given once per cycle. The crossover design allows each subject to receive both treatments with a washout period in between. During the study, researchers monitor pharmacokinetic measures such as the area under the plasma concentration curve and peak plasma concentration on day 8 after dosing. They also track adverse events and immune responses. The trial involves screening, drug administration on specified days, and follow-up assessments to evaluate safety and drug behavior. Participation lasts through both cycles including the washout and observation periods.
