About denosumab

Denosumab is marketed under two brands – it is a biosimilar to the reference products Prolia® (60 mg/ml solution for injection in PFS)  and Xgeva® (120 mg/1,7 ml solution for injection in vial), a human monoclonal antibody for the treatment of osteoporosis and fractures due to bone metastasis. Denosumab is a RANKL inhibitor which works by preventing the development of osteoclasts, which are cells that break down bone. It is used for patients with osteoporosis at high risk for fractures, bone loss due to certain medications, and in cancer patients with bone metastases or giant cell tumours of the bone.
