Entecavir triphosphate is a highly potent inhibitor of wild-type HBV Pol and is 100- to 300-fold more potent than lamivudine triphosphate against 3TC-resistant HBV Pol. It competes with dGTP to be incorporated into viral DNA.

2.Impact of peginterferon alpha-2b and entecavir hydrate combination therapy on persistent viral suppression in patients with chronic hepatitis B.
Hagiwara S1, Kudo M, Osaki Y, Matsuo H, Inuzuka T, Matsumoto A, Tanaka E, Sakurai T, Ueshima K, Inoue T, Yada N, Nishida N. J Med Virol. 2013 Jun;85(6):987-95. doi: 10.1002/jmv.23564.
The ideal approach to treat chronic hepatitis B remains controversial. This pilot study aimed to evaluate the effectiveness of peginterferon (PEG-IFN) α-2b and entecavir hydrate (ETV) as a combination therapy for patients with chronic hepatitis B, particularly in the context of virological response and the reduction of intrahepatic covalently closed circular DNA (cccDNA). A total of 17 patients with hepatitis B virus (HBV) genotype C were enrolled in this study. All subjects were treated with this combination therapy for 48 weeks and observed for an additional 24 weeks. All patients underwent liver biopsy before and after the therapy period. Changes in cccDNA levels and liver histology were monitored between biopsies. Among the 11 patients who exhibited pre-therapy hepatitis B e antigen (HBeAg), 8 (73%) showed evidence of HBeAg seroconversion by the end of the follow-up period. Serum HBV DNA levels decreased by 5.2 and 3.3 log copies/ml (mean) by the end of the therapy and follow-up periods, respectively.
