A new industry study shows that tanezumab is an effective analgesic for osteoarthritis but confirms an increased risk of rapidly progressive OA and total joint replacement seen in earlier trials.

Tanezumab is an investigational humanised monoclonal antibody that binds and inhibits nerve growth factor. It is being developed by Pfizer and Eli Lilly and Company, which funded the current trial.
