GlaxoSmithKline
  Purpose
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.

Tuberculosis (TB) Biological: Mtb72F/AS02A Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Prevention
Official Title: Double-blind (Observer-blind), Randomised, Controlled, Phase I/II Study, to Evaluate the Safety, Reactogenicity and Immunogenicity of GSK Biologicals' Candidate Tuberculosis Vaccine, Mtb72F/AS02A Administered Intramuscularly at 0, 1, 2 Months to Healthy PPD-positive Volunteers Aged 18 to 50 Years

Secondary Outcome Measures:
  • Immunogenicity as assessed by humoral and CMI response.

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.
