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 Results may not be published yet.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.

Summary

This study is testing a new blood test that looks for circular RNA, a genetic material, to detect colorectal cancer early. Researchers will collect blood samples from 600 adults with stage I-III colorectal cancer to see how accurately the test identifies the disease. If it works, this could lead to a non-invasive screening option that catches cancer sooner.

What this could mean

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

Active substance
cf-circRNA assay (blood test for circular RNA)
What this could lead to
If successful, this blood test could offer a simple, non-invasive way to catch colorectal cancer early, potentially improving survival rates.
What could go wrong
This is an early-stage study with 600 participants. The test may not be accurate enough for widespread use, and results need validation in larger, diverse populations.
