Active clinical trials for "Tuberculosis"

Assess the mycobactericidal activity of PA-824 (given at 200 mg daily) when added to first-line tuberculosis (TB) treatment (isoniazid, pyrazinamide, and a rifamycin antibiotic) over 12 weeks of treatment. Funding Source - FDA Office of Orphan Products Development (OOPD)

This is a prospective, open label, two-centre, randomized, controlled, two-stage, phase Ib/IIa study to evaluate the safety, tolerability, PK, drug-drug interaction and bactericidal activity of BTZ-043 administered orally once daily over 14 days to participants with newly diagnosed, uncomplicated, smear-positive, drug-susceptible pulmonary tuberculosis. The primary objective is to assess the safety and tolerability of BTZ-043 given over 14 days by evaluation of adverse events during treatment and follow-up period in patients with newly diagnosed, uncomplicated, smear-positive, drug-susceptible pulmonary tuberculosis.

LASER-TBM is a parallel group, randomized, multi-arm phase IIa trial evaluating the safety of increased dose rifampicin (RIF) plus linezolid (LZD), with or without aspirin (ASA), for the treatment of HIV-infected adults with tuberculous meningitis (TBM). The study will recruit 100 HIV-infected adults with TBM across four sites in South Africa. The primary endpoint is the occurrence of solicited treatment-related adverse events. Secondary endpoints include death and disability (including neurocognitive impairment), radiological outcomes, and the occurrence of immune reconstitution inflammatory syndrome (IRIS). A nested pharmacokinetic (PK) substudy aims to: Describe the plasma and cerebrospinal fluid (CSF) PK of LZD and high dose RIF. Evaluate the relationship between drug exposures, toxicity and efficacy. Compare exposures between intravenous and oral RIF administration. Investigate the impact of high dose RIF on LZD and dolutegravir (DTG).

The investigators propose to conduct a phase 2 randomised (1:1) double-blind placebo-controlled trial of the dolutegravir-lamivudine-tenofovir fixed dose combination tablet daily with an additional 50 mg dose of dolutegravir/matching placebo taken 12 hours later in ART-naïve or fisrt-line interrupted HIV-infected patients on rifampicin-based anti-tuberculosis therapy. The hypothesis is that virologic outcomes with standard dose dolutegravir-based ART will be acceptable in patients on rifampicin-based anti-tuberculosis therapy.

A Phase 1, Partially-Blinded, Placebo-Controlled, Randomized, Multiple Ascending Dose Study to Include A Single Dose Food-Effect Study to Evaluate the Safety, Tolerability, and the PK Profile of TBI-223 in Healthy Subjects

This study will evaluate new technique, microneedle, to detect latent tuberculosis (TB) in healthy volunteers

WHO recommends to take TB drugs while fasting: if TB drugs are taken with food, perhaps drug concentrations are too low; on the other hand: if this is not tolerated, drugs could also be taken with food. Do lower drug concentrations - with improved adherence to therapy - outweigh the disadvantage of lower drug blood concentrations over time? How exactly do the drug concentrations over time (pharmacokinetics) compare between fasting and fed conditions, especially in the early stage of TB treatment when patients are relatively sick, and relatively poorly tolerate TB drugs?

Flexible bronchoscopy is a common procedure performed by pulmonary physicians. The use of topical anesthesia, analgesia, and sedation during flexible bronchoscopy varies among physicians, institutions and geographic locations across the globe. Commonly used topical anesthetic agents before and during bronchoscopy include cocaine (4%),benzocaine (20%), tetracaine (1%), and lignocaine (1%-10%). Topical lignocaine is administered through the flexible bronchoscope in an attempt to reduce excessive coughing and patient discomfort. However, the optimal dosage and strength of topical lignocaine that should be used during fibreoptic bronchoscopy has long been a topic of controversy. In this study we compare the efficacy of 1% versus 2% lignocaine in controlling cough and pain in patients undergoing flexible bronchoscopy.

Tuberculosis (TB) disease is caused by bacteria that have infected the lung. TB bacteria are very small living agents that are spread by coughing and can be killed by taking TB drugs. To kill these TB bacteria TB patients have to take a combination of four drugs for 2 months and then two drugs for a further 4 months. During the first 2 months patients take rifampicin, isoniazid, ethambutol, and pyrazinamide. After that patients take only isoniazid and rifampicin for a further 4 months, making a total of 6 months therapy. In A5307 the investigators wanted to test a new combination of drugs to see if the investigators could treat TB faster in the future. Studies in animals have suggested that one of the four drugs, isoniazid, only works for a few days and may not be needed after the first two doses of TB treatment to kill the TB bacteria. After that its effects wear off to the point that it may even interfere with the other drugs. The investigators wanted to see if stopping isoniazid early, or using moxifloxacin, a different drug, instead could treat TB faster. This study was the first time that this type of regimen without isoniazid had been tested in humans. If the investigators could show that isoniazid stops working after a few days, the investigators could then try to see if they could possibly make a better tuberculosis treatment in the future.

People who are infected with HIV and tuberculosis (TB) need to receive medications that treat both diseases safely and effectively. This study enrolled infants and children infected with HIV and TB and evaluated the safety and tolerance of an antiretroviral (ARV) treatment regimen for HIV that contains raltegravir when administered with a TB treatment regimen that includes rifampicin. Study researchers aimed to determine the most effective dose of raltegravir for infants and children when taken with rifampicin.
