Latent tuberculosis infection

This study tests a new combination of medicines (BPaLMZ) against the standard treatment for tuberculous meningitis, a serious brain infection. About 240 adults, including those living with HIV, will take part. The goal is to see if the new combo helps more people survive and reco…

This trial investigates how a weekly TB prevention regimen (rifapentine and isoniazid) affects levels of the HIV drug dolutegravir in children living with HIV. Researchers will measure drug concentrations in the blood to see if the combination remains safe and effective. The stud…

This study looks at whether a higher dose of the TB medicine rifampicin is safe and works well in children with both HIV and TB. Twenty children will take their usual HIV and TB drugs, but for two weeks the rifampicin dose will be increased. Researchers will measure drug levels i…

This study tests whether a 4-week course of two TB drugs works as well as the standard 3-month course to prevent active TB in students and staff who have been exposed. About 3,520 people from schools will take either the short or standard regimen. The goal is to see if the shorte…

This study tests whether offering small financial rewards and using video calls to watch people take their medicine can help more people complete treatment for latent tuberculosis. About 399 adults in Baltimore will be randomly assigned to usual care, video check-ins alone, or vi…

This study tests whether an 8-week or 24-week pulmonary rehabilitation program (exercise and breathing training) helps people recover lung function after completing tuberculosis (TB) treatment. About 690 adults with confirmed TB will be randomly assigned to one of two rehab progr…

This study tests whether people with asymptomatic tuberculosis (TB) can be treated effectively with a shorter course of standard antibiotics—17 weeks instead of the usual 6 months. Researchers will compare the shorter regimen to standard treatment in 426 participants in China. Th…

This study is testing whether measuring TB DNA in blood and urine can help diagnose tuberculosis and track treatment progress. Current TB tests can be slow or require invasive procedures. The trial will enroll 85 people with active TB, latent TB, or no TB to see how accurate the …

This study tests whether a 4-week course of the drug bedaquiline can prevent tuberculosis (TB) as well as standard longer treatments. It involves 2,530 people living with HIV and close contacts of TB patients. The goal is to find a safer, easier-to-complete prevention option.

This study aims to find a shorter, safer treatment for latent tuberculosis (TB) infection to prevent it from becoming active disease. About 1800 adults and children with a positive TB test will try one of several daily pill regimens lasting 1 to 4 months. The goal is to identify …

This study compares a new 6-week daily rifapentine regimen to the standard 12-16 week rifamycin-based treatment for latent tuberculosis infection (LTBI). The goal is to see if the shorter treatment is just as safe and effective at preventing active TB. About 3,400 people at highe…

This study tests whether giving tuberculosis (TB) prevention drugs immediately to children and teens who live with someone with active TB can stop them from getting infected. About 647 participants aged 5 to 17 will be randomly assigned to receive either immediate treatment or st…

This study follows 150 people with active or latent tuberculosis (TB) to collect blood, sputum, and tissue samples. The goal is to better understand how TB behaves in the body and how the immune system responds. Participants receive standard TB treatment as part of the study, but…

This study follows 300 health workers in Cape Town, South Africa, who are at high risk of tuberculosis (TB) infection. Researchers will use a combination of existing and new tests every three months to track immune responses at the time of infection. The goal is to better underst…

This study looks at how different types of mycobacterial infections, including drug-resistant tuberculosis and nontuberculous mycobacteria, change the body's immune response. Researchers will collect blood and other samples from 120 participants, including healthy people and thos…

This study looks at the bacteria living in the lungs of people with active tuberculosis (TB) and how they change with treatment. Researchers will compare lung bacteria in diseased and healthy areas, and also check the mouth, nose, and gut. They aim to understand how these microbe…

This study explores whether measuring tiny DNA fragments from the TB bacteria in the blood can help doctors monitor how well treatment is working. Researchers will enroll 140 adults with newly diagnosed TB in Thailand, taking blood samples over time to see if the DNA levels drop …

This study looks at how common certain infections are among 250 asylum seekers living in reception centers in Italy. Participants must be adults who arrived in Italy between 2 and 36 months ago. The goal is to better understand infection rates to improve health screening and care…

This study looks at whether people with tuberculosis (TB) who have no symptoms can still pass the infection to others. Researchers will follow about 6,770 participants, including those with HIV, and use advanced genetic testing to track TB spread among close contacts. The goal is…
