Study Details

Study Description

Brief Summary

This study is designed to evaluate the comparability of TG103 injection subject to changes in the manufacturing process in Chinese healthy male subjects.

Condition or Disease Intervention/Treatment Phase
  • Drug: TG103 produced by the modified manufacturing process
  • Drug: TG103 produced by the original manufacturing process
 Phase 1

Detailed Description

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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: TG103 produced by the modified manufacturing process

A single dose of TG103 (15mg) produced by the modified manufacturing process will be administered subcutaneously (SC) in healthy male subjects.

Drug: TG103 produced by the modified manufacturing process
Drug: TG103 (a modified manufacturing process), 15mg, SC
Active Comparator: TG103 produced by the original manufacturing process original manufacturing process

A single dose of TG103 (15mg) produced by the original manufacturing process will be administered subcutaneously (SC) in healthy male subjects.

Drug: TG103 produced by the original manufacturing process
Drug: TG103 (the original manufacturing process), 15mg, SC

Outcome Measures

Primary Outcome Measures

  2. Area under the plasma concentration versus time curve (AUC) [Day1-5, 7,9,10, 15, and 28]

Secondary Outcome Measures

  1. Change from baseline in Fasting blood glucose(FPG) [Day1-5, and 7]

    Pharmacodynamic (PD) parameters after administration of of TG103

  2. Change from baseline in 2-hour postprandial blood glucose(2hPG) [Day1-5, and 7]

    Pharmacodynamic (PD) parameters after administration of of TG103

  3. Number of participants with treatment-emergent adverse events [Up to 28 days]

    Pharmacodynamic (PD) parameters after administration of of TG103

  4. Concentration of Antidrug antibodies(ADA) [Day1, 15, and 28]

    ADA after administration of of TG103
