Who may be able to join

AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI

Who might be able to join this trial:

  • You are a man or woman between 18 and 60 years old who has been diagnosed with asthma
  • You have smoked very little in your life — no more than 1 pack of cigarettes per year
  • You are willing to take part in the study and are able to sign a consent form to confirm this
  • You are generally in stable health based on your medical history
  • You are able to do consistent, repeatable breathing tests (where your results are very close each time you try)
  • Your lung function is at a reasonable level — specifically, a breathing test result above 60% of what is expected for someone your age and size (confirm with trial site)

Who may not be able to join:

  • You are unable to understand the study information, cannot give your own consent to take part, or cannot read the written materials provided
  • You are unable to perform the required breathing tests
  • You have any metal implants or devices in your body that cannot be removed, such as a pacemaker, neurostimulator, insulin pump, aneurysm clip, artificial limb, surgical staples, metal fragments, or ear implants — as these may not be safe in an MRI scanner
  • You have any physical or mental condition, such as severe fear of enclosed spaces (claustrophobia), that might make it difficult or unsafe for you to have an MRI scan
  • You are currently pregnant
