Filter by:This study is a U.S.-based, 1 site (with 4 clinical settings), randomized controlled trial (with funding from the Centers for Disease Control and Prevention's (CDC) Antibiotic Resistance Solutions Initiative) that will be implemented to evaluate traditional directly observed therapy (DOT) and electronic forms of DOT (eDOT) for tuberculosis (TB) treatment. The trial will assess whether eDOT that employs electronic communication methods, such as video via computer or cellphone, is a non-inferior approach to monitor TB treatment adherence, compared to traditional in-person DOT (ipDOT), in which a trained person is in the physical presence of patients as anti-TB drugs are ingested. ipDOT is the single best intervention proven to be successful when it comes to TB patients' adherence to therapy (which reduces risk of acquired drug resistance). However, ipDOT is resource intensive and many times challenging to facilitate in-person. If eDOT is found to be non-inferior to ipDOT, health departments and other clinicians might be able to provide eDOT to certain populations of TB patients in a more flexible and potentially cost-saving manner.
This observational study will examine the safety and efficacy of bedaquiline and delamanid used (individually, not together) in routine, multidrug regimens for treatment of MDR-TB. The information gathered in this study will inform doctors how best to use these TB drugs in the future.
The study is aimed to evaluate the safety and immunogenicity of the medicinal product "GamTBvac" - a recombinant subunit vaccine against the tuberculosis. The study is designed as a comparative placebo-controlled study with a two-fold increase of an applied dose among healthy volunteers aged 18-49 years.
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.
A panel of highly sensitive circulating biomarkers for acute liver injury have been identified and demonstrated to identify liver injury on first presentation to hospital before standard tests are elevated in patients with paracetamol overdose. The investigators wish to test these biomarkers in patients with active and latent tuberculosis to see if they can be used to stratify patients undertaking anti-tuberculosis drug therapy. Anti-tuberculosis drug induced liver injury is the most frequent side-effect of anti-tuberculosis therapy, affecting 2-5% of tuberculosis patients seen at the Royal Infirmary Edinburgh and hindering their effective treatment. Patients will be recruited from the TB out-patient clinic at the Royal Infirmary Edinburgh. Blood samples will be taken every time the patient visits the clinic and also retrieved from the biochemistry lab. The biomarkers in the blood samples will be analysed to determine if they rise in patients who develop liver injury.
This study is a Phase 1, single-center, open-label, single-dose study to evaluate (1) the absorption, metabolism, and excretion patterns of a single dose of [14C] PA-824, and (2) the pharmacokinetics, safety, and tolerability of a single oral-suspension dose of unlabeled PA-824 in healthy adult male subjects. Unlabeled PA-824 and [14C]-PA-824 will be administered together in an oral-suspension formulation. Enrollment is planned for one dose group of 6 subjects. All 6 subjects will receive the same treatment.
The primary objective of the study is to evaluate the safety and tolerability of single and multiple doses of TBA-7371 in healthy subjects
This is a randomized, double-blind, placebo-controlled, single ascending dose study conducted at one study center in the United States. Four (4) cohorts of 8 subjects each (6 active and 2 placebo). Subjects will participate in only one cohort. Safety will be assessed throughout the study; serial ECGs and serial blood samples will be collected for the safety and PK assessment of sutezolid. Dose escalation to the next cohort (i.e., dose level) will not take place until the Sponsor, in conjunction with the Principal Investigator, has determined that adequate safety, tolerability and PK from the previous cohort has been demonstrated to permit proceeding to the next cohort. Interim PK analyses will be performed for the dose escalation decisions to reconsider the sampling time points as the study progresses. All samples will be sent for analysis and the bioanalytical lab will be unblinded and only run the analysis on active treatment subjects. Data from the analysis used for the escalation meetings will only include active treatment subjects, and will be blinded by subject. Subjects will be housed in the clinic from at least 24 hours prior (from Day -2), until 48 hours (Day 3) after dosing. Subjects will be contacted via a phone call for follow-up questioning about adverse events 7 days later (Study Day 10).
TB is increasingly diagnosed using the GeneXpert platform, which can be used for a variety of tests (not just TB). HIV viral load monitoring is required at least annually in patients on ART to detect failure of virologic suppression, however, most HIV VL testing is done centrally. A patient with virologic failure is more likely to get TB. The investigators wish to see if Xpert done at the clinic results in faster patient TB diagnosis and treatment initiation compared to sending specimens away for central testing. In a different patient group (PLHIV returning for HIV treatment monitoring), the investigators wish to see if POC Xpert HIV-1 viral load (Xpert VL) testing results in faster patient viral load quantification compared to centralised testing. Both POC tests will use the same testing hardware. This polyvalent utility of the GeneXpert system is hitherto uninvestigated in this local setting. Newly diagnosed pre-ART HIV positive patients will be approached and asked to be a part of this study. Patients will be randomly assigned to Ultra done at the clinic or the normal off-site laboratory TB testing. The time taken for patients to get diagnosed and time-to-treatment will be recorded. We will also do exploratory diagnostic accuracy evaluations including but not limited to, Ultra when done on mouth samples, the new SILVAMP FujiLAM on urine, and host RNA blood signatures for active TB. Additionally, a different group of HIV positive patients (on ART) returning to the clinic for annual follow-up visits will also be asked to join the study. These patients will be randomly selected for either Xpert VL testing done at the clinic or the normal off-site testing. The time taken for patients to receive viral load results will be recorded. Should the patient's viral loads be found to be higher than anticipated and considered by the clinical to indicate a lack of viral suppression, the time taken for patients to have ART regimen adjusted, receive adherence counselling or received HIV drug susceptibility testing will be recorded. This project will confirm if Ultra TB testing performs well in PLHIV irrespective of symptoms and may produce evidence that supports universal TB testing in this important and vulnerable patient group, including using novel diagnostics on non-traditional specimen types. The investigators will also assess whether POC placement of Ultra and Xpert VL has benefits (e.g., more patients diagnosed for TB or VL monitored during the same day visit).
This protocol will use leukapheresis to collect lymphocytes to study immune responses following vaccination with BCG in BCG-naïve participants. These studies will include, but not necessarily be limited to: anti-T-cell and anti-Natural Killer (NK) T-cell responses, anti-lipid responses, and antibody responses to BCG following re-vaccination. These responses will provide a detailed framework characterizing the immune responses that are induced and responses that are not induced in humans by BCG, a partially protective TB vaccine. This framework will allow new hypotheses to be formulated and tested regarding what new and more effective TB vaccines should target for optimal protective immunity.
