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 Results may not be published yet.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.

Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is measuring a protein called STIM1 on the surface of immune cells in 670 people with various autoimmune diseases. The goal is to find which diseases have high levels of this protein, which could help researchers develop new antibody-based treatments. Participants provide blood samples, and no experimental treatment is given.

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 identify which autoimmune diseases have high STIM1 levels, paving the way for developing new antibody treatments.
What could go wrong
This is an observational study, not a treatment trial. It only measures a protein; it does not test any therapy. Results may not lead to actual treatments.

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