Repeat cold spray treatment for COPD with chronic bronchitis
Part of Infections, Lungs & breathing clinical trials.
This study tests a repeat treatment using a cold spray (Metered Cryospray) inside the airways of people who have COPD with chronic bronchitis. It aims to see if this spray, which you've had before in a prior study, can help improve your symptoms again.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have taken part in a previous study using a treatment called Metered Cryospray (a cold spray for the airways) and have finished both treatment sessions from that study.
- You are under 80 years old.
- You have had COPD with chronic bronchitis (a daily cough with mucus) for at least 2 years.
- Your COPD is moderate or severe (based on breathing tests) and you have been following standard treatment guidelines for at least 3 months before joining.

This study tests a new treatment that uses brief electric pulses to clear blocked airways in people with chronic bronchitis. It might help if you have a long-term cough with mucus and standard medicines aren't enough.
This study tests if the drug mepolizumab can reduce mucus blockages in the airways of people with COPD and frequent flare-ups. It may help improve breathing and reduce flare-ups.
This study tests whether a new inhaled medication called HSK39004 can help people with COPD breathe better and reduce shortness of breath. You'll receive either the medication or a placebo (inactive powder) and be monitored for safety and effectiveness.
This trial tests a new medicine, Hemay005, in adults with moderate to severe COPD who also have a chronic cough with mucus. It looks at how the drug affects certain markers in the body related to the disease.
This trial tests two forms of a new medication (HSK39004) in people with COPD. The goal is to see if they help improve breathing and are safe. Eligible participants must be between 40 and 80, have moderate to severe COPD, and be able to stop other COPD treatments during the study.
This study tests a new injectable medicine called CM310 for people with moderate to severe COPD who have chronic bronchitis and frequent flare-ups, despite using standard inhalers. It aims to see if CM310 can reduce flare-ups and improve breathing by targeting a specific type of inflammation.
