Summary
The purpose of this study was to demonstrate that participants with Paget's disease of the bone who had responded to zoledronic acid treatment as participants in the core registration studies CZOL446K2304 and CZOL446K2305 and later experienced a relapse can be successfully treated with a 5 milligram (mg) infusion of zoledronic acid.
Eligibility Criteria
Inclusion Criteria
- Written Informed Consent
- Participants with Paget's disease randomized to the zoledronic acid arm from the CZOL446K2304 and CZOL446K2305 core studies and who were responders by 6 months
- Confirmed relapse of Paget's disease of bone (i.e., serum alkaline phosphatase (SAP) above upper limit of normal (ULN), bone scan, worsening clinical symptoms)
Exclusion Criteria
- A participant previously treated with zoledronic acid who relapsed and was retreated with anti-resorptive bisphosphonate or calcitonin therapy within the last 12 months
- Bisphosphonate Hypersensitivity
- Participants with suspected/proven metastases at re-treatment
- Calculated creatinine clearance <35 milliliter/minute (mL/min) at screening
- Serum calcium level <2.07 millimole/liter (mmol/L) at screening
- Active primary hyperparathyroidism, hyperparathyroidism, hypoparathyroidism or hypothyroidism
Other protocol-defined inclusion/exclusion criteria may apply.
