Pfizer and Eli Lilly and Company announced positive top-line results from a phase 3 study evaluating tanezumab 2.5 mg or 5 mg in patients with moderate-to-severe osteoarthritis (OA) pain. The tanezumab 5 mg treatment arm met all three co-primary endpoints at 24 weeks, demonstrating a statistically significant improvement in pain, physical function and the patients’ overall assessment of their OA compared to those receiving placebo. The tanezumab 2.5 mg treatment arm met two of the three protocol-defined co-primary efficacy endpoints compared to placebo, demonstrating a statistically significant improvement in pain and physical function, while patients’ overall assessment of their OA was not statistically different than placebo. Tanezumab is a humanized monoclonal antibody that is part of an investigational class of non-opioid pain medications known as nerve growth factor (NGF) inhibitors.
