The PK/PD Study of A Single Subcutaneous Injection of SHR-1222 in Healthy Subjects

Use the Protocol Title. The Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study Following A Single Subcutaneous Injection of SHR-1222 in Healthy Subjects

This is a Single Center, Randomized, Double-Blind, Dose Escalation, Placebo Parallel Controlled PhaseⅠClinical study to Evaluate the Safety, Tolerability and Pharmacokinetics, Pharmacodynamics with A Single Subcutaneous Injection of SHR-1222 in Healthy Subjects.

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

Study Overview

• Status: Completed
• Conditions: Osteoporosis
• Intervention / Treatment: Drug: SHR-1222; Drug: Placebo

Detailed Description

50 adult healthy subjects with 5 dose groups will be enrolled in the study, including six subjects in the lowest dose group, four of whom received the SHR-1209 and two of whom received the placebo. The other three groups have 11 subjects in each group, 9 administered SHR-1222 and 2 administered placebo. The primary endpoint is the Safety and Tolerability : adverse events, vital signs, physical examination, laboratory examination, 12 lead electrocardiogram, injection site reactions, etc.
