NCT ID NCT04590833

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
The trial has finished. Results may not be published yet.
Stopped early This study
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

Details not published

Summary

This study tests whether a supervised treadmill walking program can improve memory, attention, and other thinking skills in adults with type 2 diabetes. Participants will follow a personalized exercise plan, and researchers will measure changes in cognitive function and blood markers like BDNF, a protein linked to brain health. The trial also looks at how genetics might influence who benefits most. It is a small feasibility study, so the main goal is to see if a larger trial is possible.

What this could mean

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

Active substance
Supervised treadmill walking exercise program
What this could lead to
If successful, this could pave the way for a personalized exercise program to help protect memory and thinking in people with type 2 diabetes.
What could go wrong
This is a very small feasibility study, so results may not apply broadly. It is testing whether the approach works, not yet proving it helps cognition.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Participants eligible for this study will be sedentary adults with no major chronic physical or mental disorders but classified as having low physical activity levels determined by the International Physical Activity Questionnaire. * Participants must have a documented medical diagnosis of T2DM and must be receiving diabetes care at the time of enrollment. * Participants must be English-speaking and are able to give informed consent. Exclusion Criteria: * include uncontrolled hypertension with resting blood pressure of 160/90 mmHg or higher, having symptoms of coronary ischemia such as chest pain and severe shortness of breath during activities of daily living, loss of consciousness/fainting for any reason, or having any other medical or physical conditions (such as osteoporosis, asthma, spinal cord injury) or symptoms (e.g., pain or swelling in any part of the body) that may interfere with exercise participation.
