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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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.

Summary

This completed study from France examined joint fluid from 20 people with arthritis to see if acid-sensing ion channels (ASICs) play a role in pain. Researchers wanted to find natural compounds that activate these channels during inflammation. The goal is to validate ASICs as targets for new pain treatments, but this was a basic science study, not a treatment trial.

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 research could point toward new pain medications that block ASICs, offering relief for arthritis and other inflammatory conditions.
What could go wrong
This is a very small, early-stage lab study (20 people) that only looks at joint fluid samples. It does not test any treatment, so it may not lead to a usable drug.
