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 Results may not be published yet.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

Researchers are testing an experimental drug called arhalofenate (MBX-102) in adults with gout and high uric acid levels. Participants take either arhalofenate or a placebo once daily for four weeks. The trial measures changes in blood uric acid and checks for side effects.

What this could mean

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

Active substance
arhalofenate, an experimental oral drug also called MBX-102
What this could lead to
If it works, arhalofenate could offer another way to lower uric acid in people with gout, possibly with fewer flares.
What could go wrong
This is a small, short phase 2 trial, so any benefit may not hold up in larger studies. Arhalofenate could cause side effects or fail to lower uric acid enough.
