Abstract
BACKGROUND AND OBJECTIVE: The cost-effectiveness of highly effective, but costly, peg-interferon (peg-IFN) treatment for chronic hepatitis B (CHB) infections in China is unknown. Endemic hepatitis D virus (HDV) may also modify the effectiveness of any HBV treatment option. The objective of this study is to determine the best antiviral treatment from a societal perspective in the Chinese population, which contains a mix of HBV and HDV infections. METHODS: A Markov model is developed to simulate the clinical course of CHB and chronic hepatitis D (CHD) individuals. For a hypothetical Chinese cohort of 10,000 individuals aged 30-60 years, cost-utility analysis is performed for therapies with: lamivudine, adefovir, telbivudine, entecavir, IFN and Peg-IFN. Costs and quality-adjusted life-years (QALYs) are discounted at 3 % annually. A one-way sensitivity analysis is also conducted. RESULTS: Lamivudine, adefovir, telbivudine, and entecavir are all cost-effective treatments compared to palliative care at an incremental cost-effectiveness ratio (ICER) of -$418, -$197, -$443 and -$317 per QALY, respectively (2015 US dollars). Peg-IFN yields a maximum 156,000 QALYs with an ICER of $1149 per QALY while IFN results in the highest cumulative mortality of 48 % along with the lowest QALY gained. Probabilistic sensitivity analyses confirm that only Peg-IFN and ETV are the only two cost-effective options at the current willingness-to-pay (WTP) of $12,000 in China. However, entecavir has a higher probability of being cost-effective than Peg-IFN at current WTP for all age groups. CONCLUSIONS: Peg-IFN generates maximum QALYs compared to lamivudine, adefovir, telbivudine and interferon, and presents itself as a cost-effective option at current WTP. Alternatively entecavir can be used in China, generating 10 % lower QALYs than Peg-IFN but costing less than palliative care.
