Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is Single-center, randomized, open-label, single-dose, three-period or two-period crossover study design.

The goal of the stage 1 is to preliminary evaluate the PK comparability of TJ101 injection before and after CMC change following a single subcutaneous injection of 1.2 mg/kg in healthy male subjects in China, and to assess whether the two formulations are bio equivalent.

The goal of the stage 2 is to further evaluate the PK comparability of TJ101 injection before and after CMC change following a single subcutaneous injection of 1.2 mg/kg in healthy male subjects in China, and to assess whether the two formulations are bio equivalent.
