Summary
HBe seroconversion is an important goal for anti-HBV treatment, since it is associated with
a non progressive liver infection and a better clinical outcome. However, the rate of HBe
seroconversion is low in HIV-HBV co-infected patients, mostly treated by tenofovir and
emtricitabine. This study will evaluate the efficacy and the safety of a one-year
Peg-interferon alpha 2a additional treatment in patients already treated by tenofovir and
emtricitabine without reaching HBe seroconversion.
Clinical Details
Official title: Pilot Study on Efficacy and Tolerance of Peg-interferon Alpha-2a (Pegasys) Added to Tenofovir DF and Emtricitabine (Truvada) in AGHBe Positive HBV-HIV Co-infected Patients. ANRS HB 01 EMVIPEG.
Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Primary outcome: proportion of patients with seroconversion HBe (loose of HBe antigen and acquisition of HBe antibody) and HBV DNA below 2.3 log10 copies per ml
Secondary outcome: proportion of patients with negative HBe antigen.proportion of patients with HBV DNA under 2.3 log 10 copies per ml. proportion of seroconversion HBs. proportion of patients with no more HBs antigen. proportion of patients with HBV DNA below 2.3 log 10 copies per ml in relation with 3TC resistance or not before tenofovir treatment; increased of ALT before tenofovir treatment;duration of tenofovir treatment before study. Biological evolution and histological of hepatic activity and fibrosis. Biochemical response (ALT at normal value). proportion of patients with :seroconversion HBe and HBV DNA below 2.3 log 10 copies per ml HBV and HIV resistance mutations to tenofovir DF and Emtricitabine. Immunological and virological evolution of HIV infection. Safety Quality of life Treatment adherence
Detailed description:
Many HBV-HIV co-infected patients are currently treated with dual activity drugs such as
tenofovir and emtricitabine, often in combination. However, despite the potent antiviral
activity of these drugs, the rate of HBe seroconversion is quite low, and not always
sustained over time. HBe seroconversion is an important goal for anti-HBV treatment, since
it is associated with a non progressive liver infection and a better clinical outcome. On
the other hand, treatments with antiviral and immuno-modulator activity such as
Peg-interferon, are infrequently used in co-infected patients, despite promising data in the
field of HBV mono-infection with increased rates and sustained HBe seroconversions. This
pilot study will evaluate the efficacy and the safety of a one-year Peg-interferon alpha 2a
additional treatment (180 micro-g once a week, by injection), in 55 patients already treated
by tenofovir and emtricitabine for at least 6 months, and who did not reached HBe
seroconversion
