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 Results may not be published yet.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.

Summary

This study tests whether a 20-week program of exercise alone or exercise combined with cognitive training can improve thinking and memory in breast cancer survivors. 108 women who have finished primary treatment will be assigned to one of three groups: dual-task training, exercise only, or standard physical activity advice. Researchers will measure changes in executive function, physical fitness, and blood markers linked to muscle-brain communication.

What this could mean

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

Active substance
exercise program and dual motor-cognitive training
What this could lead to
If successful, this could point toward a non-drug way to ease 'chemo brain' and improve daily life for breast cancer survivors.
What could go wrong
This is a small, early-stage study (108 people) with no blinding, so results may not apply widely. The benefits may be modest or not last after the program ends.
