About
Part I of the study: This is a randomised, single-dose, subcutaneous injection, parallel study designed to compare the PK of HLX14 and EU-sourced Prolia® in healthy Chinese adult male subjects, and to assess the safety, tolerability, and immunogenicity of these 2 drugs.
Part II of the study: This is a randomised, double-blind, four-arm, single-dose, subcutaneous injection, parallel-controlled study to evaluate the PK, PD, safety, tolerability, and immunogenicity between-group following a single subcutaneous injection of HLX14 or US, EU, CN-sourced Prolia®.
