Active clinical trials for "Tuberculosis"

HIV-infected people have an increased risk of developing active tuberculosis (TB). At the time the study was designed, the standard course of treatment for TB was 6 to 9 months of isoniazid (INH).This study compared the safety and effectiveness of a 4-week regimen of rifapentine (RPT) plus INH versus a standard 9-month regimen of INH in HIV-infected people who are at risk of developing active TB.

Goal of VPM is the development of a recombinant urease C-deficient listeriolysin expressing BCG vaccine strain (VPM1002) as a safe, well tolerated and efficacious vaccine against tuberculosis (TB) for residents in endemic areas and persons at risk in non-endemic areas. The new vaccine should be at least as potent as the current strain and should be safer than BCG (Kaufmann, 2007a; Grode et al., 2005). The vaccine is formulated as live lyophilised bacteria to be re-suspended before intradermal injection. The preceding clinical trial in 80 volunteers in Germany indicated immunogenicity and safety being sufficient for proceeding with the clinical development. Hence, the current study is commenced in South Africa, a country highly endemic for tuberculosis. 24 volunteers were randomly allocated to 4 groups each with 6 adult healthy volunteers.

This is a Phase I study whose primary outcome is to assess the safety of a new tuberculosis vaccine, FP85A, when administered individually and sequentially with MVA85A in a prime-boost regime, to healthy volunteers, who have previously been vaccinated with BCG. The secondary outcome is to assess the cellular immune response in the same population. The trial consists of 36 subjects in 3 groups. The first group will be vaccinated with FP85A alone, the second group will be vaccinated with MVA85A followed by FP85A 28 days later and the third group will be vaccinated with FP85A followed by MVA85A 28 days later.

This study is designed to evaluate the safety of the TB vaccine MVA85A in healthy children and infants in South Africa. A single vaccination with MVA85A has been shown to be safe and highly immunogenic in a wide range of subjects in previous clinical trials. In this trial,we will vaccinate 24 children with 5 x 10^7pfu of MVA85A and three groups of 36 infants with 2.5 x 10^7, 5 x 10^7 or 1 x 10^8 pfu. Participants will be identified from the general population living in Worcester, Western Cape, South Africa

The purpose of this study is to determine the efficacy of micronutrient supplementation among patients with active tuberculosis, half of who are co-infected with HIV-1

This study examines the early immune response to a new vaccine (MVA85A) being developed to combat tuberculosis (TB).

This Phase I study will evaluate the safety and immunogenicity of two doses GSK Biologicals' candidate TB vaccine (692342) according to a 0, 1, 2 months schedule in PPD-negative adults.

Tuberculosis is a current infection during HIV infection. After infectious contact, some patients will develop tuberculosis some will only be infected without symptoms, they have Latent Tuberculosis Infection (LTBI) which can reactivate later.In order to prevent this tuberculosis reactivation, LTBI diagnosis screening is preconised in HIV-infected patients. This diagnosis is made till now by the tuberculin skin test (TST) but this test is not specific of TB. New blood tests (QFTB-G and T-SPOT.TB) specific po MTB infection are now sold but have not been evaluated in immunocompromised HIV-infected patients. The primary endpoint of this study is the evaluation of the theoretic therapeutic impact of the use of IGRAS for diagnosis of LTBI in HIV-infected patients

A Phase I study of the Safety and immunogenicity of MVA85A in healthy Gambian volunteers

The purpose of this study is to determine if 30-day survival will be improved with addition of prednisone to standard tuberculosis (TB) therapy.
