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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers at Johns Hopkins are testing whether a blood test called Signatera can reliably detect tumor DNA in people with high-grade upper tract urothelial cancer, a rare cancer of the urinary tract. The study will collect blood samples before, during, and after treatment to see if changes in tumor DNA levels match how well the cancer responds. The goal is to learn whether this test can help design better future trials for perioperative therapy in this disease.

What this could mean

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

Active substance
Signatera testing, a blood test that looks for tumor DNA fragments (ctDNA)
What this could lead to
If the test proves reliable, it could help doctors monitor how well treatment works and design better clinical trials for this rare cancer.
What could go wrong
This is a small, early study with only 20 participants. The test may not always detect cancer or match with patient outcomes, and it is not yet a proven tool for guiding treatment.
