    There was a single voting question at this meeting, focusing on whether the proposed risk assessment and mitigation strategy (REMS) for tanezumab will ensure that its benefits outweigh the risks.
    After discussion, the committee voted for 1 vote and 19 votes against.

    However, the FDA usually adopts the advisory committee's recommendations when making the final review decision.

    Currently, tanezumab (2.
    5 mg, subcutaneously injected [SC], once every 8 weeks) is being evaluated for treatment: patients with chronic pain caused by moderate to severe OA that are ineffective or unsuitable for other analgesics.
    At present, OA treatment urgently needs innovation, because no new drugs have been used to treat this debilitating disease for more than ten years.
    If approved, tanezumab will become a first-in-class therapy for patients who suffer from chronic pain due to moderate to severe OA and receive insufficient pain relief from other analgesics.

    Tanezumab is a humanized IgG2 monoclonal antibody that selectively targets and inhibits bioon.

    When the body is injured, inflammation, or chronic pain, the level of NGF in the body will increase.
    By selectively inhibiting NGF, tanezumab may help prevent pain signals generated by muscles, skin, or organs from reaching the spinal cord and brain.

    Tanezumab has a novel mechanism of action that is different from currently available opioids, non-steroidal anti-inflammatory drugs (NSAID) and other analgesics.
    In the studies to date, tanezumab has not shown a risk of addiction, abuse or dependence.

    In the United States, more than 27 million people suffer from OA, of which 11 million suffer from moderate to severe OA.
    At present, the available treatment options for moderate to severe OA cannot meet the needs of all patients.
    Many patients find ways to relieve pain through a variety of treatment methods.
    If approved, tanezumab has the potential to become the first NGF inhibitor analgesic for the treatment of OA pain.

    Osteoarthritis (OA) is a chronic, progressive and disabling joint disease, which is the main cause of chronic pain.
    In the United States, an estimated 31 million people are affected by OA, of which 11 million suffer from moderate to severe OA, with an average disease lasting 9 years.
    OA puts a heavy burden on these patients-pain limits their functions, which forces them to make compromises in their daily lives, negatively affects their roles and relationships, and leads to feelings of loneliness, depression and anxiety .
    OA will also affect their ability to work in the workplace.
    There is an urgent need for innovation, because the current treatment options available for moderate to severe OA cannot meet the needs of all patients.


    Ken Verburg, head of the tanezumab development team at Pfizer’s global product development division, said: “Although we are disappointed with today’s results, we still believe that tanezumab has positive benefits for patients with moderate to severe osteoarthritis pain who are currently ineffective or inappropriate.

    Many of these patients have exhausted the available treatments, no new drugs are available for them for more than a decade, and are eager for new non-opioid treatment options.

    But they have not received enough pain relief.
    Unresolved pain will affect all aspects of their lives and cause physical, emotional, social and economic difficulties.
