简要总结
This study will investigate the safety of three fixed dose levels of tanezumab (2.5 mg, 5 mg, and 10 mg) administered at an 8-week interval by subcutaneous injection multiple (7) times during the study treatment period.
详细描述
Safety study of tanezumab in relief of osteoarthritis pain This study was terminated on 6 December 2010 following a US FDA clinical hold for tanezumab osteoarthritis clinical studies which halted dosing and enrollment of patients on 23 June 2010 for potential safety issues.
