This is a randomized, open-label, parallel-group, comparative study to evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) profiles, safety, and immunogenicity of TG103 injection produced by two different manufacturing processes in Chinese healthy male subjects. Approximately 24 eligible subjects will be randomized in a 1:1 ratio to receive a single dose of TG103 produced by the modified manufacturing process or TG103 produced by the original manufacturing process via subcutaneous (SC) injection.
This study is designed to evaluate the comparability of TG103 injection subject to changes in the manufacturing process in Chinese healthy male subjects.
