NCT00670839

Brief Summary

HIV infected patients exposed to Hepatitis B virus are more susceptible to develop a chronic and severe liver disease, with a major risk of cirrhosis and liver cancer. However, immune response to standard Hepatitis B vaccination is decreased in HIV-infected patients, compared to non HIV-infected individuals, and, in case of response, its durability has to be carefully followed up. This study compares the efficacy of two strategies of revaccination in HIV-infected patients who didn't respond to previous hepatitis B vaccination. Failure is defined by two conditions: non response to the primary immunization (2 to 4 single-dose injections received before the screening visit) and failure to a single 20 µg boost before being included in the study.

Outcome Measures

Primary Outcomes (1)

  • rate of HIV-infected patients who seroconvert one month after the last vaccination. Seroconversion is defined as anti-HBs titers equal or above 10 mUI per ml

    one month after the last vaccination (week 28)

Secondary Outcomes (2)

  • According to the vaccine strategy (single-dose or double-dose), comparison of AbHBs titers, permanence of humoral response, intensity of clinical and biological events, and predicting factors related to seroconversion

    one month after the last injection ( week 28) and month 18

  • immunological substudy: to understand genetic link between some alleles of HLA-DR and non-response to immunization

  • History of 2 to 4 injections of Hepatitis B vaccine, at any time in the past
  • No history of Hepatitis B vaccination with a double-dose schedule
  • No response to Hepatitis B vaccination: serology Hepatitis B negative (AgHBs, AbHBs and AbHBc negative) the previous twelve months and at the screening visit
  • AbHBs titers below 10 IU/ml four weeks after the boost of Genhevac-B® 20μg preceding the randomization
  • unchanged ARV treatment for the last 2 months for patients who are receiving ARV at the screening visit

  • Negative pregnancy test at the screening visit, and immediately before the Genhevac-B® 20 µg boost injection preceding the randomization

You may not qualify if:

  • Acute cytolysis in the last 3 months with transaminases equal or above 5 times the upper limit of normal for HIV-HCV coinfected patients, or transaminases equal or above 2 times the upper limit of normal for non coinfected patients
  • History of hypersensitivity to any component of GenHevac-B
  • acute opportunistic infection treated the month before the screening visit
  • Hemopathy or solid-organ cancer
  • Prothrombin factor equal or below 50% and/or platelets equal or below 50 000 per mm3
  • Immunosuppressive treatment or general corticotherapy (equal or above 0,5 mg per kg per day during at least 7 days) in the last 6 months before the screening visit
  • Immunomodulating treatment (interferon, interleukine-2,…) in the last 6 months before the screening visit
  • Splenectomy
  • Decompensated cirrhosis (Child Pugh B or C)
  • Renal failure (creatinine clearance below 50 ml/mn)
  • Other severe immunocompromised condition not related to HIV infection (solid-organ transplantation, chemotherapy in the last 6 months,….)
  • Any participation to another clinical trial plan until Week 28
