Safety of inhaled ATP cough challenges
Part of Immune system & allergy, Lungs & breathing clinical trials.
This study tests how safe and repeatable an inhaled ATP cough challenge is. It first enrolls healthy adults, then people with chronic cough or mild asthma who have not used steroid inhalers recently.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 or older.
- For healthy volunteers: no chronic cough or other lung disease, and normal breathing test (spirometry).
- For chronic cough: cough lasting more than a year that hasn't been helped by treatment or has no known cause.
- You cannot be a current smoker or have a heavy smoking history and quit less than 6 months ago.
- You must not have had a cold or chest infection within the past 6 weeks.
- You cannot have serious heart, lung, immune, or other medical conditions, or be pregnant or breastfeeding.

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.
This study is looking at how mucus builds up in the airways of people with asthma, COPD, or chronic cough. Researchers will also compare findings to healthy volunteers. The goal is to better understand these conditions and find new ways to help.
This study tests a behavior-based therapy to help you gain control over a persistent cough that hasn't responded to other treatments. You will learn techniques to reduce coughing during a 4-week program.
This study looks at airway samples from people with asthma and healthy volunteers. It helps researchers understand what causes airway problems and could lead to better treatments.
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.
This trial tests a new drug called ADO-5030 in people with mild to moderate asthma to see how it affects their airway sensitivity. Participants will have breathing tests using AMP (a substance that can trigger asthma-like symptoms) to measure the drug's effects.
