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
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 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 Results may not be published yet.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.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

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 completed study looked at immune cells in the blood and tumor tissue of 100 people with colon cancer. Researchers measured T cells and other white blood cells to understand the body's immune response. The goal was to gather knowledge, not to test a new treatment. Participants provided samples and were followed for up to 5 years.

What this could mean

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

What this could lead to
If successful, this research could help scientists better understand how the immune system reacts to colon cancer, potentially guiding future treatments.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly help patients. Results may not lead to new therapies.
