Pulmonary non-tuberculous mycobacterial infection

This study tests a special virus called a bacteriophage, combined with standard antibiotics, to treat a severe lung infection caused by Mycobacterium abscessus. The trial involves just one patient and aims to see if the virus can help clear the infection. It is an early, personal…

This study looks at whether the antibiotic omadacycline can help people with a hard-to-treat lung infection caused by Mycobacterium abscessus. Researchers will review medical records of 200 patients to see how many get better or are cured. The goal is to find out which patients b…

This study tests a drug called clofazimine for people with a chronic lung infection caused by Mycobacterium avium complex (MAC). The goal is to see if adding clofazimine to standard treatment helps clear the bacteria from sputum and improves walking ability and fatigue. About 102…

This study tests a fast point-of-care PCR test (Spotfire) that quickly identifies whether a respiratory infection is caused by a virus. The goal is to give ER doctors results faster so they can avoid prescribing antibiotics when they won't help. The trial enrolls 200 adults with …

This study looks at HIV-negative people who get opportunistic infections—illnesses that usually only affect those with weak immune systems. Researchers want to find out if these patients have unusual antibodies that block a key immune signal. Up to 224 adults in Thailand and Taiw…

This study looks at whether air samplers placed in homes can detect viruses that cause colds and flu, and how that compares to standard nasal swabs. About 422 students and their families will participate. The goal is to better understand how respiratory viruses spread through hou…

This study looks at 109 people in Virginia with nontuberculous mycobacterial (NTM) lung disease. Researchers use genetic sequencing to tell if a repeat infection is a relapse or a new infection from the environment. The goal is to better understand how the disease comes back and …

This study compares new, less invasive ways to collect samples for respiratory virus testing—like a nasal wash or saliva—against the standard deep nose swab. Researchers want to see if these gentler methods work just as well and cause less pain. About 1,000 adults in the emergenc…

This study places a rapid testing device in primary care clinics to help doctors quickly identify whether a cold-like illness is caused by a virus or bacteria. About 8,000 adults with symptoms like cough or runny nose will get a nasal swab, with results in 15 minutes. The goal is…

This study aims to understand how nontuberculous mycobacteria (NTM) spread among people with cystic fibrosis (CF). NTM infections are hard to treat and common in CF, but their sources are unclear. Researchers will track 100 participants with CF and NTM, testing dust and water in …
