This study tests an experimental nasal vaccine made from a harmless virus (Sendai virus) that is similar to the one causing croup. The goal is to see if it is safe and helps children ages 1 to 5 build protection against croup. About 54 children will receive the vaccine as nose dr…

This study tests a new drug called verekitug in 666 people with moderate-to-severe COPD, a long-term lung disease that makes breathing hard. The goal is to see if it can reduce serious flare-ups and improve lung function compared to a placebo. Participants must be current or form…

This study looks at whether treating patients at home for conditions like infections, heart failure, diabetes, and COPD can lead to better health outcomes and satisfaction compared to traditional hospital stays. Nearly 10,000 adults will receive hospital-level care at home, inclu…

This study looks at whether people with COPD and chronic bronchitis who switch from regular cigarettes to a tobacco heating system feel better and breathe easier. About 290 adults aged 40 and older who have smoked for at least 10 years will take part. Researchers will measure cou…

Researchers in Uzbekistan are studying common respiratory and heart conditions in children from birth to age 15. They will analyze medical records and examine blood samples to understand immune and antioxidant function in affected children. The goal is to develop and test improve…

This large real-world study will follow 10,000 Italian patients with COPD to see how their treatments, flare-ups, and other health conditions affect their risk of death. Researchers will collect data on medications, lung function, and heart problems over time. The goal is to bett…
