NCT ID NCT06574165

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 Results may not be published yet.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

Summary

This study looks at how mood, brain inflammation, and exercise are linked to pain in 60 veterans with fibromyalgia. Participants will do a 6-week supervised walking program and complete pain, mood, and blood tests. The goal is to understand these connections and design a better exercise program for veterans.

What this could mean

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

Active substance
Moderate Intensity Continuous Training (aerobic exercise program)
What this could lead to
If successful, this could point toward a personalized exercise program that helps veterans with fibromyalgia better manage chronic pain.
What could go wrong
This is an early-stage, small study (60 participants) focused on understanding links, not testing a treatment. Results may not apply to all fibromyalgia patients.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 60 people

The number the study aims to enrol. It can still change while the study runs.

Started

Nov 2024

Expected to finish

Oct 2026

An estimate. End dates often move.

Lead sponsor

A government agency

The lead sponsor is a US federal agency other than the NIH.

This study's own entry requirements. Only the study team can say for certain whether you qualify.
