Evenity (romosozumab)

Romosozumab is a monoclonal antibody that binds with and inhibits sclerostin, a regulatory factor in bone metabolism. Sclerostin inhibition increases bone formation and, to a lesser extent, decreases bone resorption. Romosozumab is indicated for osteoporosis treatment in postmenopausal women at high risk for fracture, defined as a history of osteoporotic fracture or multiple risk factors for fracture. It is also indicated for patients who have failed or are intolerant of other available osteoporosis therapy.

A boxed warning is included in the prescribing information to warn of an increased risk of major adverse cardiovascular events, including myocardial infarction, stroke, and death. Patients who have had a myocardial infarction or stroke within the past year should not receive romosozumab.

FDA approval was based on the FRAME study, which included over 7000 women who had a T score of -2.5 to -3.5 at the total hip or femoral neck. Patients were randomly assigned to receive romosozumab subcutaneous injections (210 mg) or placebo monthly for 12 months. Thereafter, patients in each group received denosumab 60 mg subcutaneously every 6 months for 12 months. Results showed that romosozumab was associated with a lower risk of vertebral fracture compared with placebo at 12 months (representing a 73% lower risk with romosozumab; P<.001). At 24 months, the rates of vertebral fractures were significantly lower in the romosozumab group compared with the placebo group after each group made the transition to denosumab (0.6% [21 of 3325 patients] in the romosozumab group vs 2.5% [84 of 3327] in the placebo group, a 75% lower risk with romosozumab; P<.001).
