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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 aims to discover biological markers (biomarkers) that could help doctors diagnose and track neurological autoimmune diseases such as multiple sclerosis, myasthenia gravis, and Guillain-Barre syndrome. Researchers will analyze samples from 50,000 people, including patients with these conditions and healthy volunteers. The goal is to find stable, reliable indicators that enable earlier diagnosis and personalized treatment.

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 could lead to earlier diagnosis and better monitoring of neurological autoimmune diseases, potentially improving treatment and quality of life.
What could go wrong
This is an observational study, so it will not test a treatment. Finding reliable biomarkers is challenging, and results may not apply to all patients.

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