The study has a screening period of 14 days. PK blood samples will be collected from subjects to determine the serum concentration of Secukinumab, thus to evaluate the similarity of the pharmacokinetics of the three study drugs. The investigator will perform safety evaluation for vital signs, physical examinations, injection site reaction, ECG, clinical laboratory tests and adverse events throughout the study. Immunogenicity evaluation (ADA, ADA titration and NAb) will also be evaluated.
