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
Registered, but not yet taking participants.

Completed This study
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 Results may not be published yet.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 (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

Researchers at Washington State University are testing whether tailored digital messages can increase colorectal cancer screening among American Indian and Alaska Native adults aged 50 to 75. The trial compares screening rates between people who receive the messages and those who receive usual care. The goal is to see if a simple, low-cost messaging program can help more people get screened for a cancer that is easier to treat when caught early.

What this could mean

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

Active substance
a targeted digital messaging program to encourage colorectal cancer screening
What this could lead to
If it works, this could offer a low-cost way to raise colorectal cancer screening rates in American Indian and Alaska Native communities and catch cancers earlier.
What could go wrong
Messages alone may not overcome barriers like access, transportation, or mistrust of the health system. The trial measures screening uptake, not whether it saves lives.
