Cost effectiveness of zoledronic acid in the management of skeletal metastases in hormone-refractory prostate cancer patients in France, Germany, Portugal, and the Netherlands
Objective
Cost effectiveness of zoledronic acid in the management of skeletal metastases in hormone-refractory prostate cancer patients in France, Germany, Portugal, and the Netherlands
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).
Conclusion
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.
