Clinical Trial 4648

Oklahoma City, OK 73119


Study Summary:

This is a Study of the long-term analgesic efficacy and safety of tanezumab alone or in combination with non-steroidal anti-inflammatory drugs (nsaids) versus NSaids alone in patients with osteoarthritis of the knee or hip.

This study is of an investigational drug, Tanezumab. It is for people with Osteoarthritis of the knee or hip. There will be about 2,500 volunteers in this trial in about 300 sites.
