ATP and P2X3 in chronic cough patients
Part of Lungs & breathing clinical trials.
This study looks at how certain nerve receptors (called P2X3) and a molecule called ATP might be linked to inflammation in the airways of people with chronic cough. It compares chronic cough patients to healthy non-smokers to better understand the cause of cough and find new treatment targets.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are either a healthy non-smoker (no asthma, normal lung function) OR have had a chronic cough for at least 8 weeks and been seen in a cough clinic for at least 6 months.
- If you have a chronic cough: You should have followed recommended testing and either have a cause that didn't improve with treatment OR have no clear cause (idiopathic cough).
- You must be between 30 and 70 years old.
- You must be able to read and understand study materials and give written consent.
- You should not be a current smoker (and healthy volunteers must be non-smokers for at least 12 months with a low pack-year history).

This study aims to better understand different types of chronic cough by using a new questionnaire. If you have had a cough for at least 8 weeks and do not smoke, you may be able to help.
This study looks at changes in the lower airways of people with a long-lasting cough that hasn't improved with treatment. It aims to understand why some coughs persist, which may lead to better treatments.
This study tests two treatments—nerve blockers and a cough control therapy—for people with chronic cough that hasn't improved with standard treatments or has no clear cause. The goal is to find better ways to reduce coughing and improve quality of life.
This trial tests a behavioral therapy for people whose chronic cough (lasting more than 8 weeks) hasn't improved with usual treatments like asthma or reflux medicine. You may join if your cough is triggered by things like talking, laughing, cold air, or irritants, and you have throat symptoms like irritation or hoarseness.
This study is creating a new questionnaire to measure how well people can control their cough. It includes people with different types of cough and a small number of healthy volunteers.
This study looks at how the cells lining your airways make energy and whether this is different in people with chronic cough that doesn't get better with treatment or has no clear cause. It may help doctors understand why some people cough and find new ways to treat it.
