This early-phase trial tested an inhaled drug called ARO-MUC5AC in healthy volunteers and people with asthma or COPD. The goal was to see if it is safe and how it affects lung function by targeting mucus production. The study was terminated early, so we have less information than…

This study tested an experimental drug called QBW251 in 42 adults with bronchiectasis, a lung condition that causes mucus buildup and infections. The goal was to see if the drug could reduce bacteria in the lungs and improve symptoms like coughing and breathing. However, the stud…

This Phase 1 trial tested a single dose of briquilimab in 17 adults with mild-to-moderate allergic asthma to see if it was safe and could reduce asthma attacks triggered by allergens. The study was terminated early, meaning it did not continue as planned. The main goal was to che…

This study tested a device called FreeO2 that automatically adjusts oxygen levels for people hospitalized with a COPD flare-up. The goal was to see if it could shorten hospital stays compared to manual oxygen adjustment by staff. Only 17 people took part, and the study was stoppe…

This study tested a French version of the CAPTURE tool, which uses a short questionnaire and a peak flow breath test, to find people with undiagnosed obstructive lung disease (like COPD). Over 1,000 adults aged 40 and older who had not been diagnosed with asthma or COPD took part…

This study tested a radioactive tracer called Annexin to see if it can detect early lung damage in people with COPD and in smokers. Researchers compared scans from healthy non-smokers, healthy smokers, and people with moderate to severe COPD. The goal was to find a better way to …

This study tested whether a low dose of fentanyl, a strong painkiller, placed under the tongue could help people with severe COPD feel less breathless during exercise. The trial planned to include 40 participants but was stopped early. Because it was terminated, we cannot draw cl…

This phase 2 pilot study tested a new dual bronchodilator inhaler called PT003 in 4 people with stable moderate-to-severe COPD. Researchers measured breathing patterns and lung function right after the first dose and again after 4 weeks of treatment. The goal was to see if PT003 …

This study looked at whether a gentle electrical stimulation device (TENS) placed on the skin could help people with COPD exercise longer after a serious flare-up. The plan was to compare exercise time with and without TENS in a small group of patients. However, the study was sto…

This study looked at whether doing breathing and exercise training at home works as well as doing it at a rehab center for people with chronic obstructive pulmonary disease (COPD). The goal was to see if home rehab could improve exercise tolerance just as much, while also being c…

This pilot study explored whether adding acupuncture to standard pulmonary rehabilitation can improve lung function, exercise tolerance, and quality of life in people with COPD. Thirteen adults took part, receiving either electro-acupuncture at specific points or a control acupun…

This study tested whether providing palliative care at home, through a team of doctors, nurses, social workers, and chaplains, could improve symptoms and quality of life for people with advanced cancer, heart failure, or COPD. The plan was to enroll over 1,100 patients, but the t…

This study looked at whether adding functional strength training and neuromuscular electrical stimulation to usual hospital care helps people with COPD exacerbations recover better. The 35 participants did exercises like sit-to-stand and received mild electrical pulses to their t…

This study aims to collect up to 10 years of electronic medical records and a one-time questionnaire from over 1,100 asthma and COPD patients who previously took part in the Salford Lung Study. The goal is to better understand how these lung diseases progress and how treatments w…

This study looked at why exercise training improves blood vessel function less in some people with COPD than in healthy individuals. Researchers measured blood vessel health before and after a 4-week exercise program in 69 participants, including COPD patients and healthy volunte…

This study looked at whether a weak immune response to bacteria in COPD patients leads to more lung infections and flare-ups. Researchers collected sputum, blood, and nasal swabs from 23 hospitalized COPD patients during a flare-up and again 8 to 16 weeks later. The goal was to m…

This study used a special microscope on the tip of a thin tube (bronchoscope) to look at the smallest blood vessels in the lungs of people with scleroderma or emphysema. The goal was to see how these vessels change in each disease. Only 9 patients were enrolled before the study w…
