What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Adverse Events (AEs) | An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. | 36 days | 
| Tmax of HZBio1 | Time to peak (Tmax) | 36 days | 
| Cmax of HZBio1 | peak concentration (Cmax) | 36 days | 
| Кel of HZBio1 | Кel of HZBio1 (elimination constant) | 36 days | 
| Т1/2 of HZBio1 | Т1/2 of HZBio1 (half-life) | 36 days | 
| AUC0-t of HZBio1 | AUC0-t of HZBio1 (the area under the Concentration vs. Time curve from 0 to t post-infusion) | 36 days | 
| serum uric acid level | The decrease of serum uric acid level after administration will be analyzed. | 36 days | 
| Number of Participants Positive for Nab（Neutralizing Antibody） | The changes of neutralizing antibody were observed before and after treatment. | 36 days | 
| Number of anti peg antibody | The changes of anti peg antibody were observed before and after treatment. | 36 days | 
| Number of anti PHC antibody | The changes of anti PHC antibody were observed before and after treatment. | 36 days |
