Abstract: | AbstractObjective:Zoledronic acid (ZOL) reduces the risk of skeletal related events (SREs) in hormone-refractory prostate cancer (HRPC) patients with bone metastases. This study assessed the cost effectiveness of ZOL for SRE management in French, German, Portuguese, and Dutch HRPC patients.Methods:This analysis was based on the results of a randomized phase III clinical trial wherein HRPC patients received up to 15 months of ZOL (n?=?214) or placebo (n?=?208). Clinical inputs were obtained from the trial. Costs were estimated using hospital tariffs, published, and internet sources. Quality adjusted life-years (QALYs) gained were estimated from a separate analysis of EQ-5D scores reported in the trial. Uncertainty surrounding outcomes was addressed via univariate sensitivity analyses.Results:ZOL patients experienced an estimated 0.759 fewer SREs and gained an estimated 0.03566 QALYs versus placebo patients. ZOL was associated with reduced SRE-related costs [net costs] (?€2396 [€1284] in France, ?€2606 [€841] in Germany, ?€3326 [€309] in Portugal and ?€3617 [€87] in the Netherlands). Costs per QALY ranged from €2430 (Netherlands) to €36,007 (France).Conclusions:This analysis is subject to the limitations of most cost-effectiveness analyses: it combines data from multiple sources. Nevertheless, the results strongly suggest that ZOL is cost effective versus placebo in French, German, Portuguese, and Dutch HRPC patients. |
