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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether a 12-week structured exercise program can improve heart and muscle health in breast cancer survivors aged 60 and older who had chemotherapy. Sixty participants will be randomly assigned to either supervised exercise training or a yoga and stretching program. The goal is to see if exercise can help prevent the decline in physical function and heart health that often follows cancer treatment.

What this could mean

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

Active substance
Structured exercise training (aerobic and resistance) and group-based yoga and stretching
What this could lead to
If it works, this could show that structured exercise helps older breast cancer survivors maintain heart and muscle function after chemotherapy.
What could go wrong
This is a small, early-stage study with only 60 participants. The results may not apply to all survivors, and the exercise program may not be more effective than yoga and stretching.

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 60 people

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

Started

Jul 2024

Expected to finish

Dec 2026

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

60 years and older

Sex

Female participants only

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: * Age ≥60 years * Previously diagnosed with early-stage (I-III) BC * Completed (≥1 year post) primary cardiotoxic treatment (anthracycline-based chemotherapy or trastuzumab-based biological therapy). Exclusion Criteria: * Have a history of coronary artery disease, heart failure, persistent and permanent arrhythmia (e.g. currently in atrial fibrillation), stroke, or chronic obstructive pulmonary disease * Develop signs or symptoms of myocardial ischemia (≥1mm horizontal or down-sloping ST segment depression on electrocardiogram) during the cardiopulmonary (VO2peak) test * Have any research MRI contraindications (e.g. any type of pacemaker), or any orthopedic limitation preventing exercise testing * Currently performing structured exercise training (defined as ≥30 mins/day of moderate-to-vigorous aerobic and/or resistance exercise training on ≥4 days/week) * Are unwilling to be randomized to either ExT or STRETCH
