A Study of TG103 in Chinese Healthy Adult Subjects
November 22, 2020 updated by: CSPC ZhongQi Pharmaceutical Technology Co., Ltd.
A Randomized, Double-blind, Placebo-controlled, Single Ascending Dose Phase Ia Study in Chinese Healthy Adult Subjects to Investigate the Safety, Tolerability and Pharmacokinetic of TG103
The main purposes of this study are to determine:
- To assess the safety and tolerability of a single subcutaneous injection of different doses of TG103 in healthy Chinese adult subjects.
- The pharmacokinetic and pharmacodynamic characteristics of a single subcutaneous injection of different doses of TG103 in healthy Chinese adult subjects were assessed.
