Active clinical trials for "Tuberculosis"

The current study is designed to confirm the mechanism behind the increase in serum creatinine observed during GSK1349572 therapy; specifically, the study will determine whether GSK1349572 has any effect on glomerular filtration rate (GFR) or effective renal plasma flow. Absent such effects, one may conclude that the small increases in serum creatinine observed are due to the inhibition of the tubular secretion of creatinine via organic cation transporter 2 (OCT2) consistent with in vitro data. .

The purpose of the study is to carry out multi-country (Ukraine and Mongolia), placebo-controlled, randomized Phase III trial in patients with drug-sensitive, multi-drug resistant (MDR-TB) and TB-HIV and identify efficacy and safety of whole-cell, heat-killed Mycobacterium vaccae formulated as a pill (V7) and consequently conduct confirmatory trials in intended registration countries, such as China, Russia and South Africa, etc.

The recommended treatment for latent tuberculosis infection for adults is a daily dose of isoniazid 300mg during 6 months. In Brazil, isoniazid was formulated as 100 mg tables. The treatment duration and the high pill burden compromised patient adherence to the treatment. The Brazilian National Programme for Tuberculosis requested the development of a new 300mg isoniazid formulation. The aim of the study is to compare the bioavailability of the isoniazid 300mg new formulation and three 100mg tablets of the reference formulation. The study is a randomized, single dose, open label, fasting, two-phase crossover bioequivalence study with a wash out period of 7 days (>7 half-life) in 28 healthy human volunteers. For the determination of isoniazid in human plasma, the investigators developed and validated a sensitive, simple and rapid HPLC-MS/MS method. This will support the strategy adopted by the Brazilian National Program for Tuberculosis for the treatment of latent tuberculosis. The new formulation will increase patients' adherence to the treatment and quality of life. Medical doctors in Brazil should become aware of the new formulation and the new treatment strategy in order to prescribe the right medication and avoid errors that could result in a high frequency of adverse events. Future research studies should evaluate pharmacovigilance, acceptability of the new tablet formulation and its impact on the cure rate.

This trial will evaluate the safety, tolerability, pharmacokinetics (PK), and efficacy of multiple oral doses of OPC-167832 in subjects with uncomplicated, smear-positive, drug-susceptible pulmonary tuberculosis (TB).

This study evaluates the efficacy of nursing interventions on adherence to antituberculosis medication in a paediatric cohort (aged 0-18 years) and identifies the risk factors for non-compliance. There are two phases in the study; Phase 1: retrospective descriptive analysis in children and young people receiving antituberculosis treatment (non-intervention group); and Phase 2: quasi-experimental, longitudinal, prospective study (intervention group). The results of the two phases will be compared.

The purpose of this study is to evaluate the bactericidal activity against Mycobacterium tuberculosis of celecoxib in combination with established drugs used to treat tuberculosis (TB). Pharmacokinetics (PK) and whole blood bactericidal activity (WBA) will be measured in healthy volunteers following administration of the study drugs alone and in combination.

In this trial, the investigators are assessing whether giving an increased dose of rifampicin to patients receiving the standard treatment for tuberculosis is safe and, when given for 4 months only, will also result in greater and faster killing of the tubercle bacillus in the lungs and result in relapse rates similar to those found in the World Health Organisation (WHO) recommended standard 6 month regimen.

GSK3036656 is being developed by GSK for the treatment of tuberculosis (TB). This is the FTIH study for GSK3036656 to evaluate the safety, tolerability and PK of single ascending and repeat oral doses of GSK3036656 in healthy adult subjects. The results of this study are intended to be used to identify appropriate and well-tolerated doses of GSK3036656 to be used in further studies. A food effect assessment will also be undertaken to investigate the influence of food on the PK of GSK3036656. The study will be conducted in two parts: Part A (single dose) and Part B (repeat dose). Up to two cohorts will be included in Part A. 9 healthy adult subjects will be included in each cohort. Each cohort will participate in up to 4 treatment (dosing) periods including a food effect treatment period. During each treatment period, GSK3036656 will be administered to 6 subjects and placebo will be administered to 3 subjects. The starting dose in Part A will be 5 milligrams (mg), and the maximum dose will be 1500 mg. The two cohorts in Part A will be dosed sequentially (i.e., dosing in Cohort 2 starts after dosing in Cohort 1 is completed). Initially, there will be a 14 day wash out period for individual subjects between each dose level. Study progression to Part B from Part A will be based on an acceptable safety, tolerability and PK profile in Part A. Part B will comprise up to 4 cohorts (Cohorts 3, 4, 5, and 6) each containing 10 (8 active: 2 placebo) healthy adult subjects to examine the safety, tolerability and PK of a repeated daily dose of GSK3036656 over a period of up to 14 days. Appropriate doses and dose regimens for Part B will be selected based on available safety, tolerability and PK data from Part A and/or any preceding repeat dose cohorts from Part B. Dividing the total daily dose into 2 or 3 smaller doses may be done in both Part A and Part B. Up to 18 subjects will be enrolled into Part A and up to 40 subjects will be enrolled into Part B. The total duration of the study for each subject recruited into Part A and Part B will be approximately 12 weeks and 8 weeks, respectively.

The purpose of this study is to evaluate the bactericidal activity against Mycobacterium tuberculosis of pyrazinamide in combination with allopurinol. Pharmacokinetics (PK) and whole blood bactericidal activity (WBA) will be measured in healthy volunteers following administration of pyrazinamide alone and in combination with allopurinol.

The overall goal of this exploratory proof-of-concept study is to determine whether, in participants with pulmonary tuberculosis caused by M. tuberculosis (MTB) with or without rifampin resistance-conferring rpoB-gene mutations, the combination of meropenem and amoxicillin/clavulanate with rifampin has greater early bactericidal activity (EBA) than the combination of meropenem and amoxicillin/clavulanate without rifampin.
