Denosumab: the era of targeted therapies in bone metastatic diseases

Abstract

This system constituted of the Receptor Activator of nuclear Factor-kB Ligand (RANKL), the Receptor Activator of Nuclear Factor-kB (RANK) and by the decoy Receptor Osteoprotegerin (OPG) plays a central role in bone resorption. Denosumab (AMG 162) is an investigational fully human monoclonal antibody with a high affinity and specificity for RANKL.This review will critically describe and discuss the recent results of clinical trial investigating denosumab in different settings of medical oncology. In particular, we will report the recently published data of clinical trials investigating denosumab in prevention of cancer treatment induced bone loss (CTIBL), in prevention of skeletal related events (SREs) in bone metastatic patients and the ongoing studies in prevention of disease recurrence in the adjuvant setting of solid tumours. The clinical data that will be reported in this review represent the first step in a path that will conduct us to explore new horizons in the field of bone health care in cancer patients.
