Safety and Immunogenicity of a Candidate Tuberculosis (TB) Vaccine in Healthy HIV Negative Adolescents...
TuberculosisThis observer blind study will assess the safety and immunogenicity of GSK Biologicals' investigational 692342 vaccine administered at 0, 1 month to healthy adolescents living in a TB-endemic region.
Study to Evaluate the Tolerability and Immunogenicity of Nyaditum Resae ® Probiotic Administered...
TuberculosisThis is a doble-blind, masked, compared with placebo clinical trial in pediatric population in contact with tuberculosis with or without tuberculosis infection. This trial aims to study the effect of the probiotic Nyaditum resae® at the level of specific Treg memory cells eight weeks after the first administration, and the global tolerability of the treatment. Nyaditum resae® is a preparation in the form of capsules containing heat-killed environmental mycobacteria Mycobacterium manresensis. The overall objective of the study is the effect of Nyaditum resae® on immunity, which could reduce the risk of developing active tuberculosis.
A Study to Evaluate Safety and Immunogenicity of AERAS-402 Administered in HIV-negative, BCG-vaccinated,...
TuberculosisThe available live tuberculosis vaccine Bacillus Calmette-Guérin (BCG) provides incomplete protection against pulmonary tuberculosis. For unknown reasons, a BCG revaccination or "booster", while not toxic, does not provide much additional protection. AERAS-402 presents tuberculosis antigens in the setting of a new, live, replication deficient adenovirus vaccine that may increase T cell immunity and thus protection from tuberculosis. Since BCG-vaccinated individuals are the population for which AERAS-402 might be indicated, AERAS-402 will be administered to individuals in Kenya who have already been vaccinated with BCG.
Study to Evaluate the Efficacy of GlaxoSmithKline (GSK) Biologicals' Candidate Tuberculosis (TB)...
TuberculosisTuberculosis VaccinesThe 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.
A Phase I Study to Evaluate Safety and Immunogenicity of AERAS 404 Administered in Adults
TuberculosisThis Phase I study will be conducted as a randomized, double-blind, dose-escalation study in five groups of healthy adult male and female subjects who are BCG-vaccinated, HIV-negative, and have no evidence of tuberculosis infection. Since BCG-vaccinated individuals are the target population for which AERAS 404 might be indicated, AERAS 404 will be administered to individuals already vaccinated with BCG
Safety and Immunogenicity of Nyaditum Resae® Probiotic to Protect From Tuberculosis
TuberculosisThis is a double-blind, masked, compared with placebo clinical trial in healthy volunteers with or without tuberculosis infection. This trial aims to study the effect of the probiotic Nyaditum resae® at the level of specific Regulatory T cells (Treg) memory cells one week after the first administration and the global tolerability of the treatment. Nyaditum resae® is a preparation in the form of drinkable vials containing heat-killed environmental mycobacteria. The overall objective of the study is the effect of Nyaditum resae® on immunity, which could reduce the risk of developing active tuberculosis.
Quantiferon Gold Test for Detecting Tuberculosis (TB) Infection in HIV/AIDS Patients in South Africa...
Latent TuberculosisHIVThe purpose of this study is to use a cluster randomized trial to compare the effectiveness of linking the Quantiferon-gold in-tube test (QGIT) with routine CD4 testing to the routine use of the tuberculin skin test (TST), the current standard of care for diagnosing latent tuberculosis infection (LTBI) in South Africa. The investigators hypothesize that QGIT clinics will identify LTBI and initiate isoniazid preventive therapy (IPT) in a higher proportion of patients and in a significantly faster timeframe. The cost-effectiveness of linking QGIT with routine CD4 compared to routine TST will also be evaluated, and the process of implementation of QGIT into the routine cluster of differentiation 4 (CD4) blood draw will be evaluated using a mixed method approach to identify steps that can be modified for future scale-up of the intervention.
Phase I Trial of DAR-901
TuberculosisThis is a Phase 1, randomized, controlled, double-blind, multiple-dose, dose-ranging study of DAR 901, (an inactivated whole cell mycobacterial vaccine) to be conducted in HIV negative and HIV positive adults previously vaccinated with BCG. The goals of the trial are to determine the safety, tolerability, and immunogenicity of multiple doses of the vaccine at different dose levels, ranging from 0.1 to 1 mg.
Phase IIa Clinical Study of Recombinant Mycobacterium Tuberculosis Allergen ESAT6-CFP10
TuberculosisChoose healthy subjects and patients with TB, distribute them into different dose groups according to the recombinant EC allergen dose from low to high average. Conducting clinical trials of TB-PPD or placebo as controlled arms intradermal injection. Do specific interferon gamma detection before the skin test,after the test 72h±2h and 144h±2h. Evaluate the safety of the recombinant EC allergy , and provide the appropriate dose range for phase IIb clinical trials.
Phase III Clinical Study of Efficacy and Safety of Vaccae™ to Prevent Tuberculosis
TuberculosisMycobacterium Vaccae for Injection (Trade Name "Vaccae") is a kind of bio-products developed by Anhui Zhifei Longcom Biopharmaceutical Co.,Ltd.,and got "The New Drug Certificate "in 1999. Vaccae has been approved for adjuvant therapy of tuberculosis(TB), and is also the only recommended drug in TB immunotherapy by WHO. It was approved for production and sale by Anhui Zhifei Longcom Biopharmaceutical Co.,Ltd. in 2001, and got favourable comment in therapy of tuberculosis. The purpose of this study is to add new indications for Vaccae, mainly to prevent Tuberculosis for high risk groups of Tuberculosis Infection . In December 2012, China Food and Drug Administration approved of the plan "Phase III Clinical Study of Efficacy and Safety of Mycobacterium Vaccae to Prevent Tuberculosis in high risk groups of Tuberculosis Infection". In the test, 10,000 cases whose skin tests of PPD are strongly positive are enrolled. Using random, double-blind, and placebo-controlled methods, the study is carried out to evaluate the efficacy and safety of Vaccae in preventing Tuberculosis. Meanwhile, in this test, TB incidence and degree of pathological changes of experimental group are lower than that of control group, and no drug-related SAEs are reported in treatment groups.
