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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

The aim of this clinical study is to 1) establish a healthy database for nuclear perfusion imaging of the lower extremities and 2) assess the prognostic value of radiotracer-based perfusion imaging for predicting clinical outcomes in patients with peripheral artery disease (PAD) who are undergoing lower extremity revascularization procedures. We hypothesize that radiotracer imaging of the lower extremities will provide a sensitive non-invasive imaging tool for quantifying regional abnormalities in skeletal muscle perfusion and evaluating responses to medical treatment.
