Brief summary
To determine the safety and tolerability of MG-ZG122 in Chinese healthy adult subjects
Detailed description
Main purpose: To determine the safety and tolerability of MG-ZG122 humanized monoclonal antibody injection (MG-ZG122 for short) in Chinese healthy adult subjects. Secondary objective: To study the pharmacokinetic (PK) characteristics of MG-ZG122 in healthy Chinese adult volunteers, and to provide a basis for the design of clinical trial protocols for subsequent clinical trials; To evaluate the immunogenicity of MG-ZG122 in Chinese healthy adult volunteers; Preliminary exploration of the efficacy of MG-ZG122 in Chinese healthy adult subjects Impact of Biomarkers in Physiology (PD).
Interventions
Single subcutaneous injection. Subjects with a dose of less than or equal to 2 ml were given one injection, and subjects with a dose of more than 2 ml were given two injections. A group 0.5 ml, B group 1 ml, C group 2 ml, D group 4 ml.

Intervention model description
Subcutaneous injections were 52.5 mg, 105 mg, 210 mg and 420 mg, respectively. Four patients were included in the 52.5 mg dose group (2 in the drug group and 2 in the placebo group). There were 10 cases in the other 3 dose groups (8 cases in the drug group and 2 cases in the placebo group). In accordance with the principle of dose increment, from low dose to high dose.
