Active clinical trials for "Tuberculosis"

This is a phase I study that will compare the safety and immunogenicity of candidate tuberculosis (TB) vaccine MVA85A administered by the intramuscular route and the intradermal route in healthy adult individuals who have been previously vaccinated with Bacillus Calmette-Guerin (BCG).

This is a phase II, proof of concept, randomized, double-blind, placebo-controlled study to evaluate the protective efficacy against TB disease, safety, and immunogenicity of MVA85A/AERAS-485 in healthy, HIV-infected adults. This study consists of 650 adults subjects (ages 18-50 years of age inclusive) who will receive study vaccine or placebo at Study Day 0 and again 6-9 months later. Samples for real-time evaluation of immunogenicity were to be collected from 70 subjects (immunogenicity analysis set).

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

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

INTRODUCTION. To evaluate the efficacy of three regimens of prophylactic therapy for tuberculosis in HIV-infected patients with anergy. METHODS. Prospective, multi-center, randomized, comparative, and open clinical trial. Anergy was defined as absence of induration in response to three antigens (PPD, Candida albicans and parotiditis antigen) applied by the Mantoux method. Patients were randomized into one of the following prophylactic treatment groups: isoniazid for six months (6H), rifampin plus isoniazid for three months (3RH), rifampin plus pyrazinamide for two months (2RZ) or no treatment (NT). After completion of treatment, patients were followed up for two years.

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

This is a phase I study to examine the safety and immunogenicity of MVA85A delivered intradermally into the deltoid region in volunteers who have recieved BCG in the past 20 years.

Title: Evaluation of efficacy of two different preventive therapy regimens for tuberculosis in HIV infected persons Phase: Phase III trial Population: 650 HIV positive patients without tuberculosis Number of sites: Three Tuberculosis Research centre, Chennai Government General Hospital, Chennai Government Rajaji Hospital, Madurai Study Duration: 36 months Study Objectives: To compare the efficacy of two TB preventive therapy regimens in reducing the incidence of tuberculosis and mortality among HIV-infected persons Study Design: The study will be a two-armed prospective randomized clinical trial among HIV- positive patients without active tuberculosis. Enrolled patients will be assigned to one of the two unsupervised self-administered treatment regimens i.e. EH for 6 months or INH alone for 3 years. At the end of a 3-year follow-up, incidence of TB and overall mortality will be compared in each group. Study Endpoints:The primary end point of the study will be development of tuberculosis and the secondary endpoints will include adverse drug reactions and mortality rate.
