Active clinical trials for "Tuberculosis"

Tuberculosis (TB) whole genome sequencing (WGS) allows outbreak identification and disease transmission tracking. It is hypothesized that prospective WGS-guided epidemiological investigations improve case detection compared to current best practices by adapting contact tracing strategies to local transmission patterns. A cluster randomized controlled trial (cRCT) will be performed in high TB incidence villages of Haute Matsiatra region in Madagascar. Communities will be randomized in three separate TB control strategies comparing (1) standard of care, (2) the World Health Organization (WHO) recommended best practices and (3) a novel intervention involving TB WGS cluster-guided epidemiological investigations. The incremental value of TB WGS on case notifications and reduction of TB burden will be measured. Secondary studies will be nested within this cRCT will include: A qualitative study which will increase the understanding of the factors facilitating and hindering implementation of WGS-based diagnostics within health systems. A cost effectiveness analysis study which will measure the cost effectiveness of newly implemented laboratory methods. Field and genomic epidemiology data from this project will inform future work on the design of community-level TB elimination strategies in collaboration with Madagascar National TB program

The purpose of this study is to compare the efficacy and safety of 26 weeks of delamanid (DLM) versus 26 weeks of isoniazid (INH) for preventing confirmed or probable active tuberculosis (TB) during 96 weeks of follow-up among high-risk household contacts (HHCs) of adults with multidrug-resistant tuberculosis (MDR-TB) (index cases). High-risk HHCs are those with HIV or non-HIV immunosuppression, latent TB infection, and young children below the age of 5 years.

This is a prospective, multi-center, open-label, cluster randomized controlled clinical trial conducted in school settings to estimate the non-inferiority effect of 1H3P3 compared with 3HR.

Every year, more than 3 million people with TB remain undiagnosed and 1 million die. Better diagnostics are essential to reducing the enormous burden of TB worldwide. The Assessing Diagnostics At Point-of-care for Tuberculosis (ADAPT) study seeks to reduce the burden of TB worldwide by evaluating faster, simpler, and less expensive TB triage and diagnostic tests.

The investigators want to know if ultra-short, effective treatment for latent tuberculosis (TB) infection (LTBI) could dramatically reduce the global incidence of active TB or not. The investigators hypothesize that short-course (4-week) daily isoniazid/rifapentine (INH/RPT) (1HP) is not inferior to standard -course (12 weeks) INH/RPT weekly regimen (3HP) for the prevention of TB in human immunodeficiency virus (HIV)-infected individuals.

The overall aim of this study is to assess the potential of an expanded TB testing strategy to increase the number of HIV-positive patients with microbiologically diagnosed TB who are started on treatment in adult wards of sub-Saharan Africa.

To reduce the burden of TB worldwide through more accurate, faster, simpler, and less expensive diagnosis of TB Every year, more than 3 million people with TB remain undiagnosed and 1 million die. Better diagnostics are essential to reducing the enormous burden of TB worldwide. The Rapid Research in Diagnostics Development for TB Network (R2D2 TB Network) brings together experts in TB care, technology assessment, diagnostics development, laboratory medicine, epidemiology, health economics and mathematical modeling with highly experienced clinical study sites in 10 countries

This study used a randomized, open, blank control design. A total of 6800 patients over 15 years old with latent mycobacterium tuberculosis infection who met the inclusion criteria but did not meet the exclusion criteria were randomly assigned to the experimental group and the blank control group in a 1:1 ratio, with 3400 patients in each group. The experimental group was alternately injected with 1 dose of microcard every two weeks (0-2-4-6-8-10 weeks) in the left and right hip muscle deep, with a total of 6 doses. The blank control group was not injected with drugs.

Cohort 1 was a randomized, double-blind, controlled clinical trial with a planned enrollment of 500 patients. Cohort 2 is a non-randomized, open-label clinical trial with a planned enrollment of approximately 60000 patients. Cohort I was injected with EC and TB-PPD in both arms, and cohort II was injected with EC only

Peripheral pulmonary lesions are of growing importance in respiratory field. Early detection of lung cancer, tuberculosis and other diseases often needs a bronchoscopic investigation with different types of navigation. Current randomized clinical study is intended to compare three different modalities of navigation in bronchial tree - virtual bronchoscopy (VBN), radial endobronchial ultrasound (EBUS) and combination of both techniques.
