On 27 April, Amgen announced that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion for the marketing authorization of Prolia (denosumab) for the treatment of glucocorticoid-induced osteoporosis. In 2017, Prolia was the best-selling product in the osteoporosis market, at almost $2bn, due to its high cost as a biologic and high use in postmenopausal osteoporosis. The latest label expansion will boost Prolia sales even further by targeting a new patient population with high unmet needs.

Chronic use of glucocorticoids, which are commonly used to treat many inflammatory conditions, is thought to be the major cause of secondary osteoporosis (drug-induced osteoporosis). Similar to primary osteoporosis, where the cause of the disease is typically age or hormonal disruption due to menopause, the first-line treatment for glucocorticoid-induced osteoporosis has historically been focused on alendronate and risedronate, generic drugs belonging to the bisphosphates class.
