Pulmonary emphysema

This study tested a new implant designed to release trapped air in the lungs of people with severe emphysema or COPD. Up to 48 participants received up to two procedures to place the implants. Researchers checked if the device was safe and if it improved breathing over 12 months.

This phase 2 trial tested whether infusions of PROCHYMAL, a stem cell product, are safe and can help people with moderate to severe COPD. 62 participants received either stem cells or a placebo. The main goal was to check for side effects, and researchers also looked at changes i…

This completed French registry tracked 155 adults with severe emphysema or COPD who received Zephyr Valves, tiny devices placed in the lungs to help them work better. The goal was to see if the treatment safely improves breathing over 12 months. Researchers measured lung function…

This study tested a new way to give Alpha-1 protein therapy by injecting it under the skin instead of into a vein. Seventeen adults with Alpha-1 Antitrypsin Deficiency received either a low or high dose weekly for eight weeks. The main goal was to check safety and how the drug mo…

This study tested whether the drug vapendavir can reduce breathing problems in people with COPD who catch a rhinovirus (common cold). Fifty-two adults with COPD were given either vapendavir or a placebo after being exposed to the virus. The main goal was to see if vapendavir lowe…

Researchers are studying whether volumetric high-resolution CT scans can give a detailed picture of lung damage in people with stable chronic obstructive pulmonary disease (COPD). The study enrolls 75 patients with COPD confirmed by breathing tests. Participants receive both a sp…

This phase 3 trial tested whether the drug N-acetylcysteine (NAC) can thin mucus and make it easier to cough up in adults with respiratory infections like bronchitis or bronchiectasis. About 333 hospitalized patients in China received either NAC, another expectorant (ambroxol), o…

This study tested whether taking two common blood thinners (aspirin and clopidogrel) for two weeks can improve blood flow in the lungs of smokers with COPD. Fifteen current or former smokers with and without COPD participated. The goal was to see changes on a special CT scan, not…

This study looked at 8 people with a FLNA gene mutation to see how many also had emphysema, a lung condition that damages air sacs. Participants had a chest scan, breathing tests, and a checkup with a lung doctor. The goal was to confirm if this rare genetic change is linked to u…

This study looked at 250 people to understand why some smokers develop a rare lung condition called combined pulmonary fibrosis and emphysema (CPFE). Researchers compared telomere length and genetic mutations in patients with CPFE, those with only fibrosis or emphysema, and healt…

This study tested whether a special type of CT scan (dual-energy CT) can provide useful information for planning lung valve placement in people with emphysema. Researchers enrolled 13 adults who were already scheduled for the valve procedure. The goal was to see if the scan could…
