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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 will expose 24 healthy adults to different levels of wildfire smoke in a safe, controlled room to see how it affects their lungs and brain. Researchers want to understand why some people may be more vulnerable to long-term lung diseases like asthma, COPD, and lung cancer. The goal is to find early warning signs of damage before disease develops.

What this could mean

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

Active substance
Woodsmoke (Lodgepole Pine) exposure
What this could lead to
If successful, this could help identify biological markers that predict who is at risk for chronic lung diseases from wildfire smoke.
What could go wrong
This is a very small, early-stage study (24 people) that only looks at short-term effects in a controlled lab, not real-world repeated exposure. It may not translate to long-term health outcomes.

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 24 people

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

Expected to start

Apr 2026

An estimate. Start dates often move.

Expected to finish

Aug 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

19 to 80 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

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.

Inclusion Criteria: * Healthy Adults between the ages of 19 to 80 (12 of each biological sex assigned at birth). Exclusion Criteria: 1. Current smoker (within six months before screening; potential to confound exposure effects). 2. History or current diagnosis of any respiratory conditions (including, but not limited to asthma or chronic obstructive pulmonary disease (COPD), asthma/COPD overlap) or other medical conditions that the study physician determines may impact participant safety. 3. Any comorbidities or other concerns identified by the study physician which may impact study participation. 4. For participants of child-bearing potential: Current pregnancy, or plans to become pregnant during study enrolment.
