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 Results may not be published yet.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

Summary

This study tests whether providing educational materials and mailing stool-based screening kits (FIT or Cologuard) to primary care patients can increase colorectal cancer screening rates. Participants aged 45-75 who are eligible for screening will be assigned to receive education, a mailed stool test, or usual care. The study will measure changes in cancer knowledge, how many kits are returned, and overall screening completion.

What this could mean

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

Active substance
Colorectal cancer education materials and mailed stool-based testing kits (FIT and Cologuard)
What this could lead to
If successful, this approach could increase colorectal cancer screening rates and early detection in primary care settings.
What could go wrong
This is a small pilot study, so results may not apply broadly. Some participants may not return the stool kits, limiting feasibility.
