This is a randomized, open-label, cross-over study comparing the bioequivalence of bedaquiline administered in whole tablet form versus bedaquiline administered in crushed (experimental) form in healthy adult volunteers.
The purpose of this study is to determine if the isoniazid is effective in the prevention of tuberculosis in a prison population, exposed to the high endemicity of the disease.
In this clinical research,48 cases TB (Tuberculosis patients) participants and 48 cases non-TB participants with lung disease who all meet the standard are divided into different groups through a randomized and blind method. Every subject inject intradermally ESAT6-CFP10 and TB-PPD (tuberculin purified protein derivative) in different arms of the same person by blind method. Specific gama-interferon (γ-IFN) detection is needed before the injection.Measure the induration and (or) redness of longitudinal diameter size and transverse diameter vernier caliper by vernier caliper after injection 24h, 48h and 72h. At the same time, we observe all kind of adverse events in order to assess the safety of drug.
There are four populations in Recombinant Mycobacterium tuberculosis Vaccine Freeze-dried (AEC/BC02) phase I clinical research. The clinical study adopt open research design. Population I have 25 subjects who received Tuberculin purified protein derivative(TB-PPD) skin test and specific gamma-interferon (γ-IFN)detection whose results are both negative ;Population II have 30 subjects who received Tuberculin purified protein derivative(TB-PPD) and ESAT6-CFP10 skin test in different arms , specific gamma-interferon (γ-IFN) detection whose results are all negative.We call polulation III as uninfected TB PPD positve population.This group screened 30 subjects whose ESAT6-CFP10 skin test and specific gamma-interferon (γ-IFN)detection results are both negative,but Tuberculin purified protein derivative(TB-PPD) skin test positive.50 subjects whose three kinds of detection results are all positive γ-IFN,TB-PPD and ESAT6-CFP10 ) are named as population IV. After filtrating, injecting of population I start firstly.After ensure the safety of the population I,the population II～polulation IV carry out in turn the implementation at the same time.
The study is a single centre, phase I, open, randomized, by intranasal and sublingual application trial that explored the safety and immunogenicity of 2 doses (Day 1 and Day 21) TB/FLU-01L tuberculosis vaccine in BCG-vaccinated healthy adult subjects aged 18-50 years.
This Strategic Research Project is a translational proof-of-concept study that will determine whether vitamin D3 has potential to prevent recurrent tuberculosis (TB), as indicated by enhanced resolution of pulmonary inflammation detected using 18F-FDG PET-CT scanning. The extent of pulmonary inflammation detectable on PET-CT scanning is a validated biomarker that has previously been shown to predict risk of TB recurrence in patients taking anti-TB treatment. The investigators propose to explore whether vitamin D3 can enhance resolution of PET-CT-detectable pulmonary inflammation, on the basis of extensive preliminary data from in vitro studies and a Phase 2b clinical trial that the investigators have conducted, showing that high-dose vitamin D3 accelerates resolution of peripheral blood inflammatory responses in patients with pulmonary TB. Forty vitamin D-deficient patients who have completed 6 months' TB treatment, but who still have residual pulmonary inflammation detectable on PET-CT scanning, will be allocated to receive either an 8-week course of high-dose oral vitamin D3 supplementation or placebo during the study period. The extent of pulmonary inflammation on PET-CT scanning will be compared between intervention vs. control groups at 8-week follow-up. If the study shows a positive result, it will generate valuable proof-of-concept data that could be used to support an application to conduct a large phase 3 trial of vitamin D supplementation to prevent TB recurrence.
The investigators aim to study the prevalence of latent tuberculosis infection (LTBI) using whole-blood interferon-r release assays, and determine the risk factors of LTBI in Korean health care workers.
The emergence and spread of multi-drug resistant and extensively-drug resistant strains of Mycobacterium tuberculosis (MDR/XDR-TB) have posed a great threat to global TB control and elimination, limiting treatment success rate at worrisome 50% for MDR-TB. Among various factors contributing to the development of drug resistance, low drug exposure is well recognized. To overcome this, either new drugs have to be developed or the dose of currently used therapy be optimized, or both. Fluoroquinolones (levofloxacin and moxifloxacin) and aminoglycosides are important drugs in the MDR-TB treatment regimen. Development of acquired drug resistance to these drugs could complicate and narrow down the available options, and further exacerbate to pre-XDR and XDR-TB. Objective: The main objective of this prospective clinical study is to understand the pharmacokinetics of levofloxacin in MDR-TB patients, receiving standard dosage (750-1250mg) based on the body weight and correlate drug exposure, with treatment outcomes. Study design: A prospective pharmacokinetic study Study population: 20 MDR-TB patients Intervention: Patients receive once daily oral dosing of levofloxacin (750-1250mg) based on the body weight, under MDR-TB treatment regimen of Nepal. Main study parameters/end points: The pharmacokinetic parameters(Vd, CL, AUC etc.) of levofloxacin are the primary end points of the study. The Cmax/MIC and AUC0-24h/MIC ratios are the best predictive parameters for efficacy of levofloxacin treatment and will be estimated. Pharmacokinetics will be evaluated in plasma and in oral fluid
This is a multi-center, blinded study to determine the performance of the YD Diagnostic Corporation (YD) REBA MTB-MDR® and Hain Genotype MTBDRplus V2 kit in a total of 600 clinical isolates and 900 residual sputum samples from patients with symptoms of pulmonary TB (PTB) and at risk of drug resistance. All testing was done on stored, de-identified leftover samples. The study involved three World Health Organization (WHO) Supranational Reference Laboratories with well-characterized strain collections and access to sputum samples with significant rates of drug resistance.
