Paget’s disease is the second most prevalent bone disease after osteoporosis. Affecting more than one million people, the chronic bone disorder is marked by the malfunction of the body’s regular bone building process and may result in pain, deformities and fractures.
This pooled analysis of two identical double-blind, active-controlled studies compared a single 15-minute infusion of zoledronic acid 5 mg solution to oral risedronate (30 mg per day for 60 days) in 357 patients with Paget’s disease. At six months, nearly all patients receiving one dose of zoledronic acid 5 mg solution were effectively treated. Specifically, 96 percent of patients treated with zoledronic acid 5 mg solution responded compared to 74 percent of patients who received risedronate (p<0<0<0

About Paget’s Disease
Paget’s disease of the bone is characterized by a malfunction in the way bone is built up and broken down at the cellular level, which may result in bone pain, osteoarthritis, deformities and fractures. In the normal cycle of bone life, bone breaks down and is replaced by new bone. In Paget’s disease, that cycle is disrupted and bone breaks down too quickly and replacement bone is not normal.
About Zoledronic Acid 5 mg Solution
The New Drug Application for zoledronic acid 5 mg solution is currently under review by the U.S. Food and Drug Administration (FDA) for the treatment of Paget’s disease. The US Food and Drug Administration issued an “approvable letter” for this product for the treatment of Paget’s disease of the bone in March 2005. Novartis is working with the US regulatory agency to gain approval for this indication. Zoledronic acid 5 mg solution received approval for the treatment of Paget’s disease in 27 European countries in April 2005 and in Canada in June 2005. In addition, it is being studied worldwide to evaluate its impact on several other bone disorders including osteoporosis, corticosteroid-induced osteoporosis and osteogenesis imperfecta in children.
