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 Results may not be published yet.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 study compares children with autism spectrum disorder (ASD) to typically developing children, aged 3 to 5 years. Researchers measure a substance called N-CAD in the blood and use a non-invasive brain imaging technique (fNIRS) to look at brain activity during rest and social tasks. The goal is to find differences that could help explain autism and lead to better diagnostic tools.

What this could mean

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

What this could lead to
If successful, this study could help identify biological markers for autism, potentially leading to earlier diagnosis or better understanding of the condition.
What could go wrong
This is an early observational study with only 98 participants, so results may not apply to all children with autism. It does not test any treatment.
