Background: The objective of this analysis was to evaluate the cost-effectiveness of using bendamustine versus alemtuzumab or bendamustine versus chlorambucil as a first-line therapy in patients with Binet stage B or C chronic lymphocytic leukemia (CLL) in the US. Methods: A discrete event simulation of the disease course of CLL was developed to evaluate the economic implications of single-agent treatment with bendamustine, alemtuzumab, or chlorambucil, which are indicated for a treatment-naïve patient population with Binet stage B or C CLL. Data from clinical trials were used to create a simulated patient population, risk equations for progression-free survival and survival post disease progression, response rates, and rates of adverse events. Costs from a US health care payer perspective in 2012 US dollars, survival (life years), and quality-adjusted life years (QALYs) were estimated over a patient's lifetime; all were discounted at 3% per year. Results: Compared with alemtuzumab, bendamustine was considered to be a dominant treatment providing greater benefit (6.10 versus 5.37 life years and 4.02 versus 3.45 QALYs) at lower cost ($78,776 versus $121,441). Compared with chlorambucil, bendamustine was associated with higher costs ($78,776 versus $42,337) but with improved health outcomes (6.10 versus 5.21 life years and 4.02 versus 3.30 QALYs), resulting in incremental cost-effectiveness ratios of $40,971 per life year gained and $50,619 per QALY gained. Conclusion: Bendamustine is expected to provide cost savings and greater health benefit than alemtuzumab in treatment-naïve patients with CLL. Furthermore, it can be considered as a cost-effective treatment providing health benefits at an acceptable cost versus chlorambucil in the US. © 2014 Kongnakorn et al.
