What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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

Summary

This pilot study compares two types of Category III protective suits worn by first responders during simulated disaster-response tasks. Twelve healthy adults will perform exercises at two different temperatures while wearing each suit. Researchers will measure heart rate, body temperature, reaction time, and comfort to find the best balance between protection and performance.

What this could mean

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

Active substance
Category III PPE suits (COMAT and EBO-10)
What this could lead to
If successful, this could help design better protective gear and biosensor systems for first responders facing biological hazards.
What could go wrong
This is a small pilot study with only 12 participants, so results may not apply broadly. The focus is on ergonomics and monitoring, not on testing protection against actual hazards.
