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

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 Results may not be published yet.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.

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.

Summary

This study is testing a new device that uses light and sound to detect melanoma cancer cells flowing in the blood, without needing a blood draw. The goal is to see if it can find these cells faster and more sensitively than current lab tests. About 75 people with melanoma will be tested, and each session takes about 90 minutes.

What this could mean

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

Active substance
Photoacoustic flow cytometry (PAFC) device
What this could lead to
If successful, this device could allow doctors to detect melanoma cells spreading in the blood much earlier than current tests, potentially improving monitoring and treatment decisions.
What could go wrong
This is an early-stage, small trial (75 people) testing a prototype device. It may not work as hoped, and results may not apply to all patients. The device is not yet proven or available for routine use.
