Clinical Trial Summary

This is a randomized, double-blind, international multicentre, parallel-controlled phase III clinical study. The study plans to enroll 478 postmenopausal women with osteoporosis at high risk of fracture, whom will be randomized at 1:1 to either the experiment group (HLX14) or the control group (Prolia®) based on stratification factors (BMI (< 25, 25-30, > 30) and geographic region (Asian or non-Asian)). The study includes screening period (28 days), treatment period (total 546 days, contain treatment period 1: D1-D364, treatment period 2: D365-D546), and an end-of-study visit (D547).

Description:

- Screening period: From Day -28 to -1, all female with postmenopausal osteoporosis subjects at high risk of fracture sign the informed consent form (ICF) and undergo relevant tests. Those who meet the inclusion criteria and do not meet the exclusion criteria will be randomly assigned into either experiment group (HLX14) or control group (Prolia®) at 1:1 and then enter the treatment period. Vitamin D and calcium supplementation is allowed during the screening period. - Treatment period: Subjects will receive a total of 3 doses of subcutaneous injection of HLX14 or Prolia® (once every 6 months (Q6M)). Treatment period 1: D1-D364, subjects will receive subcutaneous injection of HLX14 or Prolia® 60mg on D1 and D183. Treatment period 2: D365-D546, on D365, subjects in the Prolia® arm will be re-randomized 1:1 to either continue with a third dose of Prolia® or transition to HLX14 and receive a single dose of HLX14. Subjects in the HLX14 arm will be continue with a third dose of HLX14. - During the treatment period, subjects should taking at least 1000 mg of calcium daily and at least 400 IU of vitamin D daily until the end of study. (Dose will be adjusted by the investigator based on serum calcium) - End-of-study visit: The end-of-study visit will be conducted on D547 of the study or premature withdrawal. Only serious adverse events related to the investigational product will be recorded thereafter.
