Active clinical trials for "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.

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.

A Phase 1, Partially Blind, Placebo Controlled, Randomized, Combined Single Ascending Dose with a Food Effect Cohort (Part 1) and Multiple Ascending Dose Study (Part 2) Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of TBAJ-876 in Healthy Adult Subjects

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.

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.

Tuberculous (TB) meningitis is the most severe manifestation of TB infection, leaving up to 50% of patients dead or neurologically disabled. Current treatment is similar to treatment of lung TB, although penetration of some antibiotics into the brain is poor and the immune-pathology of TB meningitis is very different from pulmonary TB. In a recent phase II clinical trial from the investigators group, the first of its kind globally, intensified antibiotic treatment, with moxifloxacin and high dose rifampicin, strongly reduced mortality of TB meningitis. The investigators aim to examine the effect of intensified antibiotic treatment on mortality and morbidity of TB meningitis in a phase 3 clinical trial, preceded with an explorative pharmacokinetic (PK) study to examine if higher oral doses rifampicin result in exposures similar to the i.v. dose used in our phase 2 trial, since oral rifampicin could be implemented much easier in low-resource settings.
