RANK-Ligand and Mode of Action of denosumab (XGEVA®)

RANK-Ligand (RANKL) is a primary mediator of the activation of osteoclasts and of tumor associated bone disease. RANKL is responsible for the differentiation and activity of osteoclasts that are active in bone reduction. The protein OPG (osteoprotegerin), that is produced by osteoblasts, prevents the binding of RANKL to the osteoclasts, and establishes a physiological equilibrium between bone loss and bone construction. This balance is destroyed in tumor induced bone disease. The increased amount of RANKL increases the activity of osteoclasts, starting a vicious cycle: excessive osteoclast activity drives increased bone resorption; this in turn releases growth factors from the bone matrix that may perpetuate tumor activity.

Mode of action of denosumab
Denosumab is a fully human monoclonal antibody directed against RANKL, preventing the activation and differentiation of the osteoclasts by binding to its receptor RANK on the osteoclast surface.
The mode of action of denosumab in the bone metastatic environment is shown in this video.

This video describes the pathogenesis of osteolytic bone lesions in patients with multiple myeloma. Specifically, the RANK-Ligand-pathway plays an essential role in the resorption of the bone.
