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
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 This study
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 Results may not be published yet.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

Summary

This study explores whether using disinfectants containing quaternary ammonium compounds (QACs) affects health compared to alcohol-based products. Healthy university students will use these products for a month, then switch after a break, while researchers measure exposure through wristbands, blood, and urine, and track health via questionnaires, cognitive tests, and brain imaging. The goal is to understand any potential health risks from these common household chemicals.

What this could mean

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

Active substance
Quaternary ammonium compound disinfectants (laundry disinfectant, hand sanitizing wipes, surface disinfecting wipes)
What this could lead to
If this trial succeeds, it could provide evidence to guide safer use of disinfectants and inform health standards for these chemicals.
What could go wrong
This is an early-phase study with a small, specific group of healthy students, so results may not apply broadly. The health effects measured are short-term and may not reflect long-term risks.
