Brief summary
This study aims to investigate the effects of SHR-1222 on vascular inflammatory factors in patients with low bone mass.
Detailed description
In this study, total 50 patients with low bone mass will be enrolled and divided into 5 dose groups. In the lowest dose group 6 subjects will be recruited, among whom 4 will receive SHR-1222 and the other 2 will receive placebo. In each of the other 4 groups, 11 subjects will be recruited, among whom 9 will be administered with SHR-1222 and the other 2 with placebo. Levels of nitric oxide (NO), Endothelin-1 (ET-1), plasminogen activator inhibitor-1 (PAI-1) and hypersensitivity C-reactive protein (hs-CRP) will be detected in patients before and after the SHR-1222 injection.
