Pfizer, Lilly BLA for Osteoarthritis Pain
FDA has accepted for review a Pfizer and Eli Lilly BLA for tanezumab 2.5 mg administered subcutaneously for patients with chronic pain due to moderate-to-severe osteoarthritis who have experienced inadequate pain relief with other analgesics. The monoclonal antibody is part of an investigational class of non-opioid chronic pain medications known as nerve growth factor (NGF) inhibitors. The agency has set a December user fee review target date, and it plans to hold an advisory committee meeting before completing the review, the companies say.
The submission is based on data from 39 Phase 1-3 clinical studies involving more than 18,000 patients. The drug works by selectively targeting, binding to and inhibiting NGF, the companies say. “NGF levels increase in the body as a result of injury, inflammation or in chronic pain states,” they say. “By inhibiting NGF, tanezumab may help to keep pain signals produced by muscles, skin and organs from reaching the spinal cord and brain.”
Pfizer and Lilly entered into a worldwide collaboration in 2013 to develop and commercialize tanezumab.
