    Romosozumab, sold under the brand name Evenity, is a medication used to treat osteoporosis.[1] It decreases the risk of fractures of the spine.[1] It is used by injection under the skin.[1]

    Common side effect include headache, joint pain, and allergic reactions.[2] It may increase the risk of heart attacks and strokes.[3] Other side effects may include low calcium.[1] It is a monoclonal antibody that attaching to and blocks sclerostin.[1] This increases bone formation and reduces bone breakdown.[1]

    Romosozumab was approved for medical use in the United States and Europe in 2019.[1][3] In the United States it costs about $2,050 a month as of 2021.[4] This amount in the United Kingdom costs the NHS about £430.[2]

    Medical uses[edit | edit source]

    Romosozumab is used for osteoporosis to decrease the risk of fractures.[5] Two trials found that it reduced the rate of vertebral fracture. In one, there was a 73% lower risk of vertebral fracture after one year, and the benefit was maintained after a second year of taking denosumab. In the other, one year of romosozumab followed by one year of alendronate had a 50% vertebral fracture reduction compared to two years of alendronate.[5]

    Dosage[edit | edit source]

    It is used at a dose of 210 mg once a month for up to a year.[1]

    Side effects[edit | edit source]

    Common side effects include headache, joint pain, and pain at the site of injection.[6] It may increase the risk of heart attacks, strokes, and deaths from cardiovascular disease.[6]

    Mechanism of action[edit | edit source]

    Mechanism of romosozumab[7]

    Romosozumab inhibits sclerostin from inhibiting bone formation which it usually does via binding to LDL receptor-related proteins 5/6 of osteoblasts. As a consequence, Romosozumab permits Wnt signaling in osteoblasts which promotes bone formation [7]

    History[edit | edit source]

    Romosozumab was approved for medical use in Japan in January 2019,[5] the United States in April 2019[5] and the European Union in December 2019.[8] It was originally discovered by Chiroscience,[9] which was acquired by Celltech (now[when?] owned by UCB).[10] Celltech entered in a partnership with Amgen in 2002 for the product's development.[11]

    The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication.[12]
