The first measurement must occur one month after the reference value and must be above the reference value. The second confirmatory measurement taken one month after the first measurement must be greater than the first measurement.\n* Previous chemotherapy or radiotherapy must have been performed ≥ 8 weeks prior to study entry.\n* Eastern Cooperative Oncology Group (ECOG) score of 0, 1 or 2 (patients that spend less than 50% of time in bed during the day)\n* Adequate liver function - serum total bilirubin concentration less than 1.5 x upper limit of normal value\n* Age: ≥ 18 years\n* Patient has given written informed consent prior to any study-specific procedures. Patients with psychiatric or addictive disorders which prevent them from giving their informed consent must not enter the study.\n\nExclusion criteria:\n\n* Prior treatment with a bisphosphonate\n* Abnormal renal function as evidenced by a calculated creatinine clearance < 30 ml/minute.\n* Corrected (adjusted for serum albumin) serum calcium concentration < 8.0 mg/dl (2.00 mmol/L) or ≥ 12.0 mg/dl (3.00 mmol/L).\n* Patients with clinically symptomatic brain metastases\n* History of diseases with influence on bone metabolism such as Paget's disease and primary hyperparathyroidism\n* Severe physical or psychological concomitant diseases that might impair compliance with the provisions of the study protocol or that might impair the assessment of drug or patient safety, e.g. clinically significant ascites, cardiac failure, NYHA III or IV, clinically relevant pathologic findings in ECG\n* Known hypersensitivity to zoledronic acid or other bisphosphonates\n* Use of other investigational drugs 30 days prior to the date of randomization\n* Known history or present abuse of alcohol or drugs\n* Subjects who, in the opinion of the investigator, are unlikely to cooperate fully during the study\n* Current active dental problems including infection of the teeth or jawbone (maxilla or mandibular); dental or fixture trauma, or a current or prior diagnosis of osteonecrosis of the jaw (ONJ), of exposed bone in the mouth, or of slow healing after dental procedures.\n* Recent (within 6 weeks) or planned dental or jaw surgery (e.g. extraction, implants)\n\nOther protocol defined inclusion/exclusion criteria may apply."
