Background: In the United States, the addition of bev to 1st-line chemotherapy in mCRC provides an additional 0.10 quality-adjusted life years (QALYs) at an incremental cost-effectiveness ratio (ICER) of $571,240/QALY (Goldstein et al. Journal of Clinical Oncology, 2015). However, this estimate of value is not transferrable between countries due to variable international pricing strategies. Our objective was to establish the cost-effectiveness of bev in mCRC in 5 different countries: the US, the UK, Canada (CAN), Australia (AUS), and Israel (ISR). Methods: We performed the analysis on the basis of a previously published Markov model (Goldstein et al. JCO, 2015). Input data for efficacy, adverse events and quality of life were considered to be standard for all countries. We used country specific prices for all healthcare services, medications, and administration costs. For the UK, all costs were obtained from UK Department of Health, National Health Service and British National Formulary. For CAN, all costs were obtained from the Ontario Drug Benefit formulary, Ontario Schedule of Benefits, and Sunnybrook Pharmacy Stores Department. For AUS, all costs were obtained from the Pharmaceutical Benefits Scheme and the Australian Medicare Benefits Schedule. For ISR, all costs were obtained from the Israeli Ministry for Health and Clalit Health Services. All costs were converted from local currency to US dollars in December 2015. Probabilistic sensitivity analyses (PSA) assessed the model robustness against the parameter uncertainties. Results: Base case results are displayed in the table. PSA demonstrated 0% likelihood of bev being cost cost-effective in any country at a willingness to pay threshold of $150,000 per QALY. Conclusions: Although there are differences in the value of bev between countries, the addition of bev to first-line chemotherapy for mCRC is not cost-effective across all 5 countries analyzed. This study provides a novel framework for analyzing the value of a cancer drug with a single model from the perspectives of multiple international payers.
