What the trial is, and whether it could suit you
This is an open-label, randomized, single-dose, parallel comparison bioequivalence study conducted in healthy adult male subjects.
The study is divided into 3 parts, each of which evaluates the bioequivalence of GZR18 Injection for one strength before and after CMC changes.
Subjects eligible for each part of the screening will be randomized into Group A or Group B in a 1:1 ratio. Each subject will receive a single dose of GZR18 Injection, followed by PK blood sampling and safety follow-up for 35 days. Subjects will be admitted to the hospital 1 day predose, follow a standardized light diet that evening, and then fast for at least 10 h thereafter. On the day of administration, GZR18 Injection of a single strength will be administered subcutaneously under fasting conditions at a site approximately two finger-widths (2.5 cm) away from the umbilicus on the abdomen. Lunch and dinner will be
