Study to Evaluate the Persistence of the Cellular and Humoral Immune Response Following Vaccinations With GlaxoSmithKline (GSK) Biologicals' Candidate Vaccines Containing HBsAg and Different Adjuvants in Healthy Adult Volunteers

May 24, 2017 updated by: GlaxoSmithKline

A Long-term Follow-up of a Phase I/II Study to Compare the Persistence and to Perform in Depth Characterisation of the Cellular and Humoral Immune Response Following Vaccinations With GSK Biologicals' Candidate Vaccines Containing HBsAg and Different Adjuvants in Healthy Adult Volunteers

The purpose of this long-term follow-up study was to evaluate the persistence of the cellular and the humoral immune response 4 years after the first dose of GSK Biologicals' investigational vaccine formulations containing HBsAg (used as a model antigen) and an adjuvant.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Subjects in this long-term follow-up study were recruited among those subjects who completed the study 287615 (NCT00508833) and who were enrolled in specific groups. All subjects were vaccinated in the study 287615 (NCT00508833) according to a 0, 1, 10 month schedule. No new subjects were enrolled and no vaccine was administered in this long-term follow-up study. There was a single visit at Year 4 at which blood samples for immunogenicity assays were taken.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
