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 This study
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 Results may not be published yet.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

Summary

This study tests whether a structured endurance exercise program, like walking or cycling, after finishing chemotherapy can help prevent colorectal cancer from returning. About 92 patients who have completed adjuvant chemotherapy will be randomly assigned to either an exercise program or their usual physical activity. Researchers will track how long they live without cancer coming back and overall survival.

What this could mean

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

Active substance
endurance exercise program
What this could lead to
If it works, this could show that a structured exercise program after chemotherapy helps prevent cancer from coming back and improves survival.
What could go wrong
This is a small, early-stage trial with only 92 participants, so results may not apply to everyone. Previous studies on exercise after chemotherapy have had mixed results.
