What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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 Results may not be published yet.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
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
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study investigates whether 6 weeks of treadmill walking with blood flow restriction cuffs on the legs can improve immune cell function in adults with type 2 diabetes. Participants walk three times per week, with some wearing inflatable cuffs that partially limit blood flow. Researchers measure changes in T-cell energy use and immune markers before and after the program.

What this could mean

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

Active substance
blood flow restriction training
What this could lead to
If it works, this could point toward a simple exercise method to boost immune health in people with type 2 diabetes.
What could go wrong
This is a small, early-stage study with only 20 participants, so results may not apply widely. The training involves leg cuffs that may cause discomfort or rare complications.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 20 people

The number the study aims to enrol. It can still change while the study runs.

Started

Feb 2026

Expected to finish

Dec 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

19 to 64 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

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

Inclusion Criteria: A. Aged 19-64 years. B. Diagnosed with type 2 diabetes with current HbA1c 5.7-9.0% C. Completing \<150 minutes of moderate-vigorous physical activity per week. Exclusion Criteria: A. Chronic musculoskeletal condition or recent (within 2 years) cardiovascular event preventing participation in exercise. B. Unstable type 2 diabetes medication of the last 3 months C. Absolute contraindications to BFR (i.e., peripheral vascular disease) D. A self-reported diagnosis of low iron concentrations, anemia, or being treated for these conditions E. A diagnosis of any red blood cell-altering condition (i.e., sickle cell anemia, poikilocytosis) F. Currently living with any cardiovascular disease, which would impact the ability to participate in exercise safely G. Currently prescribed any medication which would impact the ability to use a heart rate monitor to accurately track intensity
