LUNG DISEASES

This study tested a new oral drug called ralinepag in 687 adults with pulmonary arterial hypertension (PAH), a serious lung condition that makes the heart work harder. Participants took ralinepag or a placebo on top of their usual PAH medications. The main goal was to see if rali…

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…

This study tested whether taking vitamin D every day could reduce lung complications in children and teens with sickle cell disease. Lung problems like infections, asthma attacks, and acute chest syndrome are major causes of illness and death in this condition. Researchers gave d…

This study is testing a portable, non-invasive breath analyzer that measures tiny particles in exhaled breath to screen for conditions like type 2 diabetes, liver disease, kidney disease, and lung disease. Researchers will enroll healthy volunteers and people with known diagnoses…

This study tested whether a simple checklist and blood test (the YEARS algorithm) can safely rule out pulmonary embolism (a blood clot in the lungs) in people with active cancer, compared to the standard approach of doing a CT scan on everyone. About 700 cancer patients with susp…

This study tested a team-based approach to managing sedation in children with acute respiratory failure who need a breathing machine. The goal was to reduce the number of days on the ventilator. Over 2,400 children from multiple hospitals participated, comparing the team approach…

This study tested freezing the nerves between the ribs during robot-assisted lung surgery to see if it reduces pain and the need for painkillers afterward. 33 adults having lung surgery were randomly assigned to get the nerve freeze or standard pain medicine. Researchers tracked …

This study tested whether giving lidocaine or alfentanil before inserting a bronchoscope can reduce coughing when spraying numbing medicine into the airways. 108 adults with lung tumors received one of these drugs or a placebo before the procedure. Researchers measured cough seve…

This study looked at immune cells called alveolar macrophages in the lungs of 18 people with non-infectious lung diseases. Researchers used a technique called flow cytometry to study the surface proteins on these cells. The goal was to better understand the role of these cells in…

This study looked at whether using a bedside ultrasound device to measure blood clotting can reduce the amount of blood products given during double-lung transplantation. The trial involved 128 adult patients. The goal was to see if this quick test helps doctors make better decis…

This study tested a new navigation device called AirWaze, designed to help doctors perform lung biopsies using CT scans. 37 adults with lung lesions underwent a bronchoscopy procedure with the device. The main goals were to see if the device was easy to use and if it could accura…

This completed study from Johns Hopkins University compared two methods for taking lung tissue samples during a bronchoscopy: a 1.1mm cryoprobe (which freezes tissue) versus standard 2.0mm forceps (which grab tissue). The trial enrolled 500 adults scheduled for a lung biopsy and …

This study tested a new device called Neola® that monitors the lungs of newborn babies. Ten preterm and term infants were enrolled to see if the device is safe and works well. The main goal was to check for any skin reactions or other side effects.

This study looked at whether a person's blood group antigens are linked to asthma attacks. Researchers followed 126 people with asthma to see if certain blood types had more flare-ups requiring steroids. The goal was to understand, not treat, the disease.

This study looked at whether firefighters have different lung scan results compared to non-firefighters, and if a blood test can help better predict lung cancer risk. Over 700 current and retired firefighters took part. The goal was to improve early detection of lung cancer and o…

This early-stage study looked at whether people with pulmonary arterial hypertension (PAH) have low carnitine levels and if taking carnitine supplements could help. Ten adults with PAH kept food diaries and had blood tests to measure carnitine. The goal was to gather information …
