Juvenile Idiopathic Arthritis
Conditions
Brief summary
To evaluate the safety and tolerability of single subcutaneous injection of Genakumab for Injection in Chinese healthy adult volunteers
Detailed description
There are 5 dose groups with 8 participants in each group, including 6 participants in the experimental group and 2 participants in the placebo control group. Since the strength of experimental drug is 150mg/1ml/ bottle, participants with a single dose of more than 150mg need to be given subcutaneously at different sites in two or more times
Interventions
150 mg/1ml/bottle, single subcutaneous injection.
The placebo contains other excipients except Genakumab, and its appearance is consistent with that of Genakumab for injection, 150 mg/1ml/bottle, single subcutaneous injection.
