Romosozumab was approved for injection in the United States and EU in 2019 and in many countries in 2020 (Evenity).
Structure and properties
Romosozumab is a humanized Ig2 monoclonal antibody with a molecular mass of 149 kDa produced by biotechnological methods.
Effects
Romosozumab (ATC M05BX06) promotes bone formation and, to a lesser extent, additionally inhibits bone resorption. The effects are due to inhibition of the glycoprotein sclerostin, which is produced by osteocytes and inhibits osteoblast function, differentiation, proliferation, and survival. Sclerostin exerts its effects by binding to receptors on the surface of osteoblasts.
