ABSTRACT
BACKGROUND@#Nucleos(t)ide analog (NA) in combination with peginterferon (PegIFN) therapy in patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) shows better effectiveness than NA monotherapy in hepatitis B surface antigen loss, termed "functional cure," based on previous published studies. However, it is not known which strategy is more cost-effective on functional cure. The aim of this study was to analyze the cost-effectiveness of first-line monotherapies and combination strategies in HBeAg-positive CHB patients in China from a social perspective.@*METHODS@#A Markov model was developed with functional cure and other five states including CHB, compensated cirrhosis, decompensated cirrhosis, hepatocellular carcinoma, and death to assess the cost-effectiveness of seven representative treatment strategies. Entecavir (ETV) monotherapy and tenofovir disoproxil fumarate (TDF) monotherapy served as comparators, respectively.@*RESULTS@#In the two base-case analysis, compared with ETV, ETV generated the highest costs with $44,210 and the highest quality-adjusted life-years (QALYs) with 16.78 years. Compared with TDF, treating CHB patients with ETV and NA - PegIFN strategies increased costs by $7639 and $6129, respectively, gaining incremental QALYs by 2.20 years and 1.66 years, respectively. The incremental cost-effectiveness ratios were $3472/QALY and $3692/QALY, respectively, which were less than one-time gross domestic product per capita. One-way sensitivity analysis and probabilistic sensitivity analyses showed the robustness of the results.@*CONCLUSION@#Among seven treatment strategies, first-line NA monotherapy may be more cost-effective than combination strategies in HBeAg-positive CHB patients in China.
