Tuberculosis Clinical Trial
Official title:
Efficacy of GSK Biologicals' Candidate Tuberculosis (TB) Vaccine GSK 692342 Against TB Disease, in Adults Living in a TB Endemic Region
The purpose of this study is to evaluate the protective efficacy of two doses of GSK Biologicals' candidate TB vaccine against pulmonary TB, as compared to placebo. The efficacy will be evaluated in adults living in TB endemic countries and aged 18 - 50 years because pulmonary TB occurs frequently in these countries and age range. In addition, the safety and immunogenicity of the candidate tuberculosis vaccine will be evaluated in a subset of volunteers.
Case Definitions:
• First case definition: A subject with clinical suspicion of pulmonary TB disease, with MTB
complex identified from a sputum specimen, taken before initiation of TB treatment, by Xpert
MTB/RIF and/or microbiological culture and confirmed HIV-negative at the time of TB
diagnosis.
• Second case definition: A subject with clinical suspicion of pulmonary TB disease, with MTB
complex identified from a sputum specimen, taken before initiation of TB treatment, by Xpert
MTB/RIF and confirmed HIV-negative at the time of TB diagnosis.
• Third case definition: A subject with clinical suspicion of pulmonary TB disease, with MTB
complex identified from a sputum specimen, taken up to four weeks after initiation of TB
treatment, by Xpert MTB/RIF and/or microbiological culture and confirmed HIV-negative at the
time of TB diagnosis.
• Fourth case definition: A subject with clinical suspicion of pulmonary TB disease, with MTB
complex identified from a sputum specimen, taken up to four weeks after initiation of TB
treatment, by Xpert MTB/RIF and/or microbiological culture.
• Fifth case definition: A subject for whom a clinician has diagnosed TB disease and has
decided to treat the patient with TB treatment.
