Filter by:TB043 is a clinical challenge trial primarily to evaluate the safety of BCG challenge administered by the aerosol inhaled route in healthy, BCG naive (Group 1-7) as well as historically BCG vaccinated UK adults (Group 8) . The trial will also look to evaluate and compare the amount of BCG recovered from the lungs as various points after challenge.
endTB-Q Clinical Trial is a Phase III, randomized, controlled, open-label, non-inferiority, multi-country trial evaluating the efficacy and safety of two new, all-oral, shortened regimens for multidrug-resistant tuberculosis (MDR-TB) with fluoroquinolone resistance.
The purpose of this study is to assess the efficacy, safety and tolerability of a combination of levofloxacin, linezolid, cycloserine and pyrazinamide (or clofazimine if resistant to pyrazinamide) treatments for 24 to 32 weeks (regimen consisted of clofazimine for 36~44 weeks) in subjects with multidrug-resistant tuberculosis (MDR-TB) compared to WHO standardized shorter regimen of 36-44 weeks.
The purpose of this study is to evaluate safety, immunogenicity of ID93+GLA-SE compared to placebo following three intramuscular (IM) injections on Days 0, 28 and 56 in BCG-vaccinated QFT-negative healthy adolescent. The healthy adolescent will all have had the childhood TB vaccine called BCG, and all of them must have a negative result for a blood test for exposure to the bacteria that cause TB (QuantiFERON-TB Gold Plus, or "QFT"). Study participants will be followed for 12 months after the last injection for safety reasons. Blood will be drawn for laboratory tests for safety and immunogenicity tests. The study hypothesis is that the vaccine is safe and immunogenic in this study population.
The purpose of this study is to evaluate the experimental tuberculosis (TB) vaccine called ID93+GLA-SE. The safety, immunogenicity, and efficacy of ID93+GLA-SE will be compared to placebo, after three intramuscular (IM) injections one month apart in healthy healthcare workers. The healthcare workers will all have had the childhood TB vaccine called BCG, and all of them must have a negative result for a blood test for exposure to the bacteria that cause TB (QuantiFERON-TB Gold Plus, or "QFT"). Study participants will be followed for 12 months after the last injection for safety reasons. Blood will be drawn for laboratory tests for safety, immunogenicity, and efficacy tests. Efficacy will be evaluated by further QFT testing. The study hypothesis is that the vaccine is safe, immunogenic, and effective in this study population.
The investigators want to know if ultra-short, effective treatment for latent tuberculosis (TB) infection (LTBI) could dramatically reduce the global incidence of active TB or not. The investigators hypothesize that short-course (4-week) daily isoniazid/rifapentine (INH/RPT) (1HP) is not inferior to standard -course (12 weeks) INH/RPT weekly regimen (3HP) for the prevention of TB in human immunodeficiency virus (HIV)-infected individuals.
The proposed work is based on the finding that one-third of the world is infected with the bacteria Mycobacterium tuberculosis (Mtb) and only 10% of these individuals develop TB. The study aims to identify factors that drive progression to disease and study signals (markers of the immune response) that detect who will progress to active TB and why this happens. Armed with these markers, the study will address how malnutrition and worms alter this signal profile to cause active TB. The work will be conducted in India, where there are 2.8 million TB cases each year - more than any other country - and where the government has committed to eliminating TB by 2035. Data suggest that malnutrition and parasites increase risk of TB disease so the investigators will feed malnourished household contacts and have those with parasites receive medication to treat these. Using this infrastructure, the investigators will evaluate the immunologic impact of feeding on TB pathogenesis. An additional aim is to understand the role of parasitic worms with the goal of determining the utility of low-cost ($.02 per dose) worm treatment as part of TB control efforts. Risk of developing TB will be evaluated for 120 household contacts of TB patients in the setting of their malnutrition and parasites. There are four study arms comprised of thirty participants each -- malnourished with parasite infection, malnourished with no parasite infection, well-nourished with parasite infection, and well-nourished with no parasite infection. Correlates of risk of disease will be assessed using blood messenger RNA/micro RNA (mRNA/miRNA) sequencing and T cell immune markers. The TB LION study will confirm that malnutrition and worms increase the risk of active TB and will provide the basis for effective interventions that could change the face of the TB pandemic and have a profound impact on the health of people worldwide. Participants in this study will be household contacts of tuberculosis index cases. The index cases in this study do not participate in the study once a household contact is established. All interventions and follow up are only being conducted within the household contact cohort. All intervention supplies, treatments, and biologics will be purchased internationally.
A pragmatic open, three-arm individually-randomised controlled trial and economic evaluation will be conducted in one primary health care centre in Blantyre, Malawi, where HIV and TB are major contributors to early mortality. Participants will be adults with symptoms of tuberculosis (cough of any duration) attending the primary clinic with an acute care episode. We will exclude adults who have taken treatment for TB within the previous 6-months, who are taking isoniazid preventive therapy, who are not resident of Blantyre, or who plan to move out of Blantyre in the following 6-months. Participants will be randomly allocated into one of three groups: Group 1: Standard of care: Participants will be seen by facility health workers and receive clinician-directed screening for HIV and TB according to Malawi national guidelines. Group 2: Optimised HIV testing and treatment linkage: Participants will be offered testing for HIV using rapid oral fluid kits by research assistants. Those with confirmed HIV infection will be linked to the HIV care clinic where facility healthworkers will screen for TB using standard sputum-based diagnostics. Group 3: Optimised TB diagnosis, HIV screening and treatment linkage: Participants will receive a high-throughput and high-sensitivity TB screening intervention, in addition to the HIV testing intervention. This will comprise of an initial digital chest x-ray classified by the CAD4TB image-recognition software as either "high probability of TB", or "low probability of TB". Participants whose x-rays are suggestive of TB will receive confirmatory sputum testing with Xpert MTB/Rif Ultra cartridges, whilst participants whose x-rays have a low probability of TB will be referred to facility healthworkers for routine care. All participants will be seen at the health facility at day 56, where they will be tested for HIV (if not on ART) and screened for TB. The Primary Trial Outcome will compare between groups the time to tuberculosis treatment initiation by day 56. The trial is sufficiently powered to permit 3 pairwise comparisons between groups (i.e. Group 1 vs. 2; Group 2 vs. 3; and Group 1 vs. 3). This three-arm pragmatic trial design allows us to efficiently answer two separate, important public health questions: firstly, by comparing Group 2 to Group 1, we should be able to determine whether HIV care should be prioritised for adults with TB symptoms. Additionally, by comparing Group 3 to Group 2, we will provide strong evidence for the effectiveness of an optimised and integrated HIV and TB diagnostic and treatment linkage approach.
This is a phase 2, double-blind, randomized (1:1), placebo-controlled trial with two parallel groups. - H56:IC31 (investigational vaccine) - Placebo 900 HIV-negative adults with a diagnosis of drug susceptible pulmonary TB are planned to be included, recruited from TB clinics with established relationships to the trial sites at the start of their TB treatment. 5 study sites in South Africa: 2 sites from the AURUM institute (Klerksdorp and Tembisa) and 3 in Cape Town at TASK Applied Science (TASK), the University of Cape Town Lung Institute (UCTLI) and South African Tuberculosis Vaccine Initiative (SATVI) under UCT, respectively. 1 study site in Tanzania (TZ): 1 site at Mbeya Medical Research Centre (MMRC) under the National Institute for Medical Research (NIMR).
The main purpose of the CoDISEN cohort study is to propose a model of prevention and care for HIV and viral hepatitis adapted to the needs of people who inject drugs (PWID) in Dakar, Senegal.
