ABSTRACT: Background
Despite the high efficacy and safety associated with direct-acting antivirals (DAAs), access to HCV treatment has been frequently restricted because of the high DAA drug costs.Objectives
To (1) compare HCV treatment initiation rates between HCV monoinfected and HCV/HIV coinfected patients before (pre-DAA period) and after (post-DAA period) all-oral DAAs became available; and to (2) estimate the HCV treatment costs for payers and patients.Research design and methods
A retrospective analysis of the MarketScan® Databases (2009-2016) was conducted for newly diagnosed HCV patients. Multivariable logistic regression was used to estimate the odds ratio (OR) of initiating HCV treatments during the pre-DAA and post-DAA periods. Kruskal-Wallis test was used to compare drug costs for dual, triple and all-oral therapies.Results
A total of 15,063 HCV patients [382 (2.5%) HIV coinfected] in the pre-DAA period and 14,896 [429 (2.9%) HIV coinfected] in the post-DAA period were included. HCV/HIV coinfected patients had lower odds of HCV treatment uptake compared to HCV monoinfected patients during the pre-DAA period [OR, 0.59; 95% confidence interval (CI), 0.45-0.78], but no significant difference in odds of HCV treatment uptake was observed during the post-DAA period (OR, 1.08; 95% CI, 0.87-1.33). From 2009 to 2016, average payers' treatment costs (dual, $20,820; all-oral DAAs, $99,661; p < 0.001) as well as average patients' copayments (dual, $593; all-oral DAAs $933; p < 0.001) increased significantly.Conclusions
HCV treatment initiation rates increased, especially among HCV/HIV coinfected patients, from the pre-DAA to the post-DAA period. However, payers' expenditures per course of therapy saw an almost fivefold increase and patients' copayments increased by 55%.
