Abstract

Abstract : Background: In the U.S., the addition of bevacizumab to first‐line chemotherapy in metastatic colorectal cancer (mCRC) has been demonstrated to provide 0.10 quality‐adjusted life years (QALYs) at an incremental cost‐effectiveness ratio (ICER) of $571, 000/QALY. Due to variability in pricing, value for money may be different in other countries. Our objective was to establish the cost‐effectiveness of bevacizumab in mCRC in the U.S., U.K., Canada, Australia, and Israel. Methods: We performed the analysis using a previously established Markov model for mCRC. Input data for efficacy, adverse events, and quality of life were considered to be generalizable and therefore identical for all countries. We used country‐specific prices for medications, administration, and other health service costs. All costs were converted from local currency to U.S. dollars at the exchange rates in March 2016. We conducted one‐way and probabilistic sensitivity analyses (PSA) to assess the model robustness across parameter uncertainties. Results: Base case results demonstrated that the highest ICER was in the U.S. ($571, 000/QALY) and the lowest was in Australia ($277, 000/QALY). In Canada, the U.K., and Israel, ICERs ranged between $351, 000 and $358, 000 per QALY. PSA demonstrated 0% likelihood of bevacizumab being cost‐effective in any country at a willingness to pay threshold of $150, 000 per QALY. Conclusion: The addition of bevacizumab to first‐line chemotherapy for mCRC consistently fails to be cost‐effective in all five countries. There are large differences in cost‐effectiveness between countries. This study provides a framework for analyzing the value of a cancer drug from the perspectives of multiple international payers. Abstract : The cost and value of cancer treatment is under scrutiny worldwide. The objective of this study was to evaluate the cost‐effectiveness of bevacizumab in the first‐line treatment of metastatic colorectal cancer (mCRC) from the perspective of payers across five selected countries, namely the U.S., U.K., Canada, Australia, and Israel.
