Study Description
Brief Summary:
The purpose of this study is to assess the loss of HbsAg after a 48-week pegylated interferon alpha 2a in patients with chronic hepatitis B (HBeAg negativation)

Condition or disease Intervention/treatment Phase
Chronic Hepatitis B AgHbs Negativation Drug: Pegylated interferon-alpha-2a Drug: Nucleotidic or Nucleosidic Treatment Phase 3

Detailed Description:

The purpose of this study is to provide a therapeutical alternative to the use of an extended or undeterminated duration of treatment with prolonged nucleoside (s)/nucleotide (s)analog (s).

The duration of administration is not consensual, and in most cases followed by a virological relapse, so that, the prolonged use could lead to the occurrence of viral resistance and mutations.

It is therefore expected that treatment with pegylated interferon for 48 weeks in patients with undetectable HBV DNA by analog(s) may increase and promotes the loss of HbsAg and then promotes HbsAg seroconversion. In the absence of cirrhosis, the loss of HbsAg at 6 months would allow the end of treatment

Outcome Measures

Primary Outcome Measures :
  1. HbsAg negativation at week 96 [ Time Frame: W96 ]
    Percentage of patients with negative HbsAg at W96, i.e 12 months after a 48 weeks treatment with pegylated interferon
