• Trial end date: 2020-12-31
• Target enrollment: 0
• Participant gender: Female

Summary

This is a Multi-Center, Randomized, Double-Blind, Dose Escalation, Placebo Parallel Controlled PhaseⅠClinical study to Evaluate the Safety, Tolerability and Pharmacokinetics, Pharmacodynamics, Immunogenicity with Multiple Subcutaneous Injections of SHR-1222 in Postmenopausal Osteoporosis Patients.

The primary objective of this study is to investigate the safety and tolerability of a range of subcutaneous SHR-1222 in postmenopausal osteoporosis patients. Secondary objectives are to determine the pharmacokinetics (PK), pharmacodynamics (PD) profile of SHR-1222 in postmenopausal osteoporosis patients including assessment of immunogenicity.
