OSPOMYV (denosumab-dssb)
Ospomyv is a RANK ligand inhibitor indicated to treat osteoporosis and increase bone mass in patients at high risk for fracture. It is used for postmenopausal women and men with osteoporosis, as well as individuals with glucocorticoid-induced osteoporosis. The medication is also approved for patients undergoing specific hormonal therapies for cancer, including men with nonmetastatic prostate cancer and women with breast cancer.
How OSPOMYV Works
Ospomyv binds to RANKL, a protein essential for the formation, function, and survival of osteoclasts, which are the cells responsible for bone resorption. By preventing RANKL from activating its receptor on the surface of osteoclasts and their precursors, the drug inhibits the breakdown of bone tissue. This process decreases bone resorption and increases bone mass and strength in both cortical and trabecular bone.

WARNING: SEVERE HYPOCALCEMIA IN PATIENTS WITH ADVANCED KIDNEY DISEASE Patients with advanced chronic kidney disease (eGFR <30 mL/min/1.73 m 2 ), including dialysis-dependent patients, are at greater risk of severe hypocalcemia following denosumab products administration. Severe hypocalcemia resulting in hospitalization, life-threatening events and fatal cases have been reported [see Warnings and Precautions (5.1) ] . The presence of chronic kidney disease-mineral bone disorder (CKD-MBD) markedly increases the risk of hypocalcemia in these patients [see Warnings and Precautions (5.1) ] . Prior to initiating Ospomyv in patients with advanced chronic kidney disease, evaluate for the presence of CKD-MBD. Treatment with Ospomyv in these patients should be supervised by a healthcare provider with expertise in the diagnosis and management of CKD-MBD [see Dosage and Administration (2.2) and Warnings and Precautions (5.1) ] .
