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.
It is a randomized, double-blinded, single-dose, 3-arm parallel, comparative study to evaluate the pharmacokinetics, safety and immunogenicity of BAT2306 Injection vs Cosentyx® (EU-licensed and US-licensed) in healthy Chinese male subjects. A total of 216 healthy male subjects are planned to be included and randomized at a ratio of 1:1:1 to receive single 150mg BAT2306 Injection or Cosentyx® (EU-licensed and US-licensed).
