- Registration Number
- NCT06641388
- Lead Sponsor
- Akeso
- Brief Summary
This is a phase I clinical study to evaluate the pharmacokinetics (PK) similarity of single dose subcutaneous injection of Ebronucimab with different production processes in Chinese healthy male subjects.
- Detailed Description
This is a randomized, parallel controlled, phase I clinical study to evaluate the pharmacokinetics (PK) similarity of single dose subcutaneous injection of Ebronucimab with different production processes in Chinese healthy male subjects. This study consists of two parts: pre-trial part and formal-trial part, with a planned enrollment of approximately 180 healthy male participants from China.

- Primary Outcome Measures
Name Time Method Area under curve (AUC) Baseline till last follow-up visit( up to day 43 or day 57) Assess the AUC of Ebronucimab
Maximum (peak) plasma concentration (Cmax) Baseline till last follow-up visit( up to day 43 or day 57) Assess the Cmax of Ebronucimab
Incidence of adverse events(AE) From the time of signing the informed consent form till last follow-up visit( up to day 43 or day 57) An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product temporally associated with the use of study treatment, whether or not considered related to the study treatment.
