About this study

Understanding the impact exercise has on a cancer survivor's gut microbiome can improve the health and well-being of cancer survivors by enhancing treatments targeting the gut microbiome. Although scientific studies support a link between exercise and the gut microbiome, rigorous randomized trials needed to confirm this causal link are limited and usually involve supervised exercise. Hence, this proposal tests feasibility of a home-based, remote-only research protocol that is more accessible to cancer survivors unable to attend supervised exercise including but not limited to rural populations. This study will also determine if exercise effects on the gut microbiome differ by factors such as race.

Read the detailed description

Forty physically inactive breast cancer survivors will be randomized into 10-week conditions of home-based aerobic exercise training or standard attention control. All participants will be asked to maintain their pre-study diet and attempt to maintain their body weight while participating in the study. Assessments will occur at baseline, week 5 (mid-intervention), and week 10 (post-intervention) by videoconference platform. Study feasibility and changes in the gut microbiome will be assessed.

  • Home-based exercise interventionBehavioural

    A 10-week home-based exercise intervention including weekly video conferences with exercise specialists.

Study groups in NCT05000502
Study groupRoleWhat they receive
Home-based aerobic exercise trainingExperimentalhome-based aerobic exercise condition will receive a fitness bracelet (with heart rate measurement capability) and weekly exercise counseling from an exercise trainer (i.e., exercise physiologist) by videoconference. The weekly counseling will be guided by the fitness bracelet data (both participant and exercise trainer will share the same log in information). The aerobic exercise progression will gradually increase duration and intensity of aerobic exercise with the goal of improving cardiorespiratory fitness.

Model description
40 breast cancer survivors will be randomized (like flipping a coin) to one of two study conditions: 1) home-based aerobic exercise training (with aerobic exercise progression targeting improved cardiorespiratory fitness) or 2) standard attention control (stretching exercises). All participants will be asked to maintain their usual diet and avoid change in body weight during the study.

Questions about this trial

What is this clinical trial studying?

A study testing Home-based exercise intervention in people with Female Breast Cancer, run by University of Alabama at Birmingham at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Feasibility - Recruitment (time frame: Baseline). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Mar 2024.
