What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether installing a radon mitigation system in homes can improve asthma symptoms. Researchers will compare a real system to a sham (inactive) system in 180 adults with uncontrolled asthma. The goal is to see if lowering radon levels leads to fewer days with asthma symptoms.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
radon mitigation system
What this could lead to
If it works, this could show that reducing radon in homes helps control asthma symptoms, offering a new management strategy.
What could go wrong
This is an early-stage trial with no phase, and the effect of radon on asthma is not yet proven. The sham group may also show improvement, making it hard to see a clear benefit.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 180 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Jun 2026

An estimate. Start dates often move.

Expected to finish

Apr 2030

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

5 to 25 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

1. Have physician-diagnosed asthma at least 1 year prior to the screening visit 2. Have evidence of uncontrolled disease as defined by at least one of the following: Use of an asthma medication during the prior 12 months, report of asthma symptoms over the prior 12 months (wheezing/whistling in the chest)(3) OR One or more asthma-related hospitalization, emergency room visit OR Unscheduled clinic or urgent care facility visit resulting in a burst of systemic steroids (3 days or more of prednisone or equivalent; 1 or more doses of dexamethasone) in the previous 12 months Exclusion Criteria 1. Not residing at the household for at least 5 days a week or family planning to move from the current home within the next twelve months, or homes with active radon mitigation systems (if home uses a HEPA filter air purifier, family must agree to disable the purifier for 28 days prior to randomization). 2. Lung disease, other than asthma, that requires daily medication (inflammatory diseases, chronic lung diseases aside from asthma, congenital cardiopulmonary conditions requiring medication or surgical treatment), 3. Homes with active HEPA filters will be excluded (even though the role of HEPA filters on radon and radon particles s is expected to be minimum and other exposures can be adjust for in the analysis) 4. Cardiovascular disease that requires daily medication, excluding hypertension 5. Taking a beta-blocker 6. Currently receiving unstable level of Immunotherapy (allergy shots) 7. Coordinator/PI judgment 8. Inability to perform lung function testing 9. Intake of abuse drugs or alcohol, have psychiatric disorders or severe mental disability that interferes with answering questions or following instructions.
