Exercise may boost metabolism in aggressive breast cancer patients

NCT ID NCT07484776

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 Results may not be published yet.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.

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This status has not been confirmed recently, so it may be out of date.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 how well the body of women with early triple-negative breast cancer can switch between burning fat and sugar for energy—a trait called metabolic flexibility. Researchers will test if different types of exercise (moderate cardio, high-intensity cardio, or strength training) can improve this flexibility, muscle strength, body composition, and quality of life. Forty women will be tracked from diagnosis through treatment and a 12-week exercise program.

What this could mean

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

Active substance
exercise training (cardiovascular at FATmax, cardiovascular at MAP, or resistance training)
What this could lead to
If successful, this could show that specific exercise programs improve metabolic flexibility, strength, and quality of life for TNBC patients.
What could go wrong
This is a small, early-phase study with only 40 participants. Results may not apply to all patients, and exercise benefits may be modest or not sustained.

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 40 people

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

Started

Feb 2026

Expected to finish

Mar 2028

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

20 to 55 years

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: * Female between 20-55 years of age. * Confirmed histological new diagnosis of stage I to III triple-negative breast cancer and a candidate to receive systemic neoadjuvant treatment with chemotherapy +/- immunotherapy. * Must not have started systemic treatment for the neoplastic disease. * Participating in any external physical exercise program or sports activities during the experimental study phase. * Inability to understand and provide written Informed Consent (IC) Exclusion Criteria: * Having neurological or orthopedic disease at the time of recruitment or during the study evaluation and intervention. * Inability to understand Spanish language. * Presenting absolute contraindications for performing a cardiopulmonary exercise test (CPET) such as heart failure, myocarditis, acute pericarditis, severe aortic stenosis, aortic dissection, vascular toxicity, uncontrolled severe arterial hypertension, uncontrolled severe cardiac arrhythmias, pulmonary thromboembolism, or severe anemia. * Have relative contraindications for performing a CPET such as bradyarrhythmias or tachyarrhythmias, moderate valvular stenosis, inability to perform physical or mental exertion, chronic infectious diseases, musculoskeletal disabilities, ventricular aneurysm, second- or third-degree atrioventricular block, or severe arterial hypertension.
