Brief summary

This is a randomized, double-blind, placebo-controlled, dose-escalation phase I clinical study. A sequential design is used in this trial with a single dose escalation climb test, to investigate the safety, tolerability, and PK/PD characteristics of GZR18 injection in Chinese obese/overweight subjects.

Exclusion criteria

* Lactating women. * History of fainting with blood and needles. * Known or suspected allergy to study related products; or drug/food allergy history; or allergy-related diseases history. * Subjects who have participated in other clinical trials and given investigational drugs or medical device interventions within 90 days before screening. * History of drug abuse within 1 year before screening, or positive results in drug abuse screening (urine). * Smokers who smoke ≥ 5 cigarettes per day within the previous 3 months before screening or cannot refrain from smoking throughout the trial period. * Any vaccine has been used within 28 days before administration, as well as any vaccine that may be used throughout the trial period. * Other scenarios judged by the investigator to render the subjects unsuitable for participating in this study.
