Safety and Immunogenicity of GSK Biological's Candidate Tuberculosis Vaccine Mtb72F/AS02A in Healthy PPD-positive Adults

Phase 2

Completed

• Conditions: Tuberculosis (TB)

• Registration Number: NCT00146744
• Lead Sponsor: GlaxoSmithKline

Brief Summary

This study will evaluate the safety, reactogenicity and immunogenicity of Mtb72F/AS02A in healthy European volunteers who are PPD-positive either via previous vaccination with BCG and/or conversion to PPD positivity through exposure to Mycobacterium tuberculosis.

Detailed Description

The BCG vaccine has been widely available for several decades. It is easy and cheap to produce, and when given to neonates or young children it is effective in preventing severe manifestations of disease such as meningeal tuberculosis and miliary tuberculosis. However, in terms of the capacity of the vaccine to protect adult humans it shows a wide range of efficacy, including zero levels of protection. Due to the general realization that BCG is losing its protective effect, particularly in terms of preventing adult-onset tuberculosis, a major effort has been made to try to develop new alternative vaccines. One such candidate, Mtb72F/AS02A, is a polyprotein derived from two known M. tuberculosis antigens adjuvanted with AS02A. Mtb72F/AS02A is a candidate TB vaccine under development for two indications: prevention of primary TB infection in young children in highly endemic areas and as an adjunct to treatment for TB in adolescents and adults.
