Non-investigational Study to Evaluate Adenovirus Serotype 5 (Ad5) Neutralizing Antibodies (nAb) in Patients With Chronic Hepatitis B Virus (HBV) Mono-infection

February 1, 2016 updated by: Transgene

Objectives:

Primary Objective:

To identify and preselect patients with chronic HBV mono infection, who are undetectable for anti-Ad5 nAb, currently being treated with nucleo(t)sides, for participation in the TG1050.02 Phase1/1b First in Man (FIM) study.

Secondary Objectives:

To assess the prevalence of undetectable anti-Ad5 nAb in chronic HBV mono-infected patients.

Methodology:

Patients with chronic HBV mono-infection, who are currently being treated with nucleo(t)sides for their HBV infection, will be enrolled in this study to measure Ad5 nAb levels. A single peripheral blood collection (4 mL) will be obtained and Ad5 nAb titers will be measured by a central laboratory using a newly validated assay.
