Breathing training may help breast cancer survivors get moving

NCT ID NCT05193149

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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether training the muscles you use to breathe can improve how long obese breast cancer survivors can exercise. Researchers will compare breathing exercises plus aerobic exercise to aerobic exercise alone in 78 women who finished treatment. The goal is to see if this helps them feel less tired and move more easily.

What this could mean

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

Active substance
inspiratory muscle training (breathing exercises) and supervised aerobic exercise
What this could lead to
If it works, this could offer a simple, drug-free way to help obese breast cancer survivors feel less tired and exercise more easily.
What could go wrong
This is a small, early-stage trial (78 people) looking at short-term changes in exercise time. The results may not apply to all survivors, and the training might not improve daily life.

Study facts

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.

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

18 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.

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

Inclusion Criteria: * completed active treatment for a Stage 0-III breast cancer diagnosis within 6 months to 5 years of enrollment. * obese as defined by a body mass index (BMI) of 30 to 50 kg/m2 * patients who are on adjuvant endocrine therapy will be allowed to participate. * sedentary (participating in less than 90 min of moderate intensity activity per week) and have at least one limitation in activity on the 10-question RAND-36 Physical Function Subscale to ensure some exercise intolerance Exclusion Criteria: * functional limitations that make independent exercise unsafe * metastatic breast cancer * ongoing or active infection with recent antibiotics or steroids * Bilateral Axillary lymph node dissection (ALND) of \>5 lymph nodes on each side, which could increase risk of lymphadenopathy with repeated blood pressure measurements during exercise or if patient has been advised by their clinician to avoid repeated BP measures on both arms. Bilateral Sentinel Lymph Node Biopsy (SLNB) will be allowed. * heart disease precluding exercise (congestive heart failure, unstable angina pectoris, cardiac arrhythmia) * psychiatric illness/social situations that would limit compliance with study requirements * orthopedic or neuromuscular disorders or arthritis that preclude participation in exercise * unwilling or unable to follow protocol requirements * pregnant or nursing * any condition which in the investigator's opinion deems the subject an unsuitable candidate to participate in this study * presence of provokable ECG changes suggestive of heart disease, or dangerous arrhythmias or exercise induced hypertension, etc. during the cardiopulmonary exercise test * non-English speaking
