Study Arms:
- zoledronic acid (Type: EXPERIMENTAL): 4 mg 15 minutes IV infusion. If creatinine clearance is ≤ 60, dosage should be adjusted as follows:CrCl 50-60: 3.5 mg; CrCl 40-49: 3.3 mg; CrCl 30-39: 3.0 mg.

Based on this trial design, predict the completion outcome and termination type (if applicable).
