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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers at the Max Planck Institute of Psychiatry are studying whether combining brain imaging, EEG, blood tests, and cognitive assessments can predict which people with treatment-resistant depression respond to lithium. The study enrolls 130 adults with major depressive disorder who have not improved after at least one antidepressant and for whom lithium augmentation is clinically indicated. Participants undergo detailed clinical and biological testing, and researchers use machine learning to look for a pattern that might forecast response. The study does not assign treatment; patients and their doctors decide on lithium as part of routine care.

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 the signature works, doctors could one day estimate who is likely to benefit from lithium before starting it, sparing others from a treatment that may not help.
What could go wrong
This is an observational study, not a test of whether lithium works. The signature may fail to predict response accurately, and it may not apply to patients outside this group.
