Tanezumab
Tanezumab is a monoclonal antibody against nerve growth factor as a treatment for pain. Tanezumab was discovered and developed by Rinat Neuroscience and was acquired by Pfizer in 2006.
In 2009 there was a Phase III trial for knee pain due to osteoarthritis.
Another Phase III trial for hip pain in OA was halted in June 2010 when some patients needed hip replacement.
Tanezumab is undergoing Phase II clinical trials for the treatment of various pain entities, including chronic low back pain, bone cancer pain, and interstitial cystitis.
In March 2012, the Anti-NGF Testing - FDA Committee voted in favor of a continuation of the development of nerve-blocking medications, as long as certain safety precautions were observed.
A Phase III trial published in 2013 found tanezumab was superior to placebo for painful hip osteoarthritis.
At February 19, 2019 the co-development partners - Eli Lilly and Pfizer - announced that treatment with tanezumab 10 mg met the primary endpoint, demonstrating a statistically significant improvement in chronic low back pain at 16 weeks compared to placebo.
