Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In detail, the aim of this research project is to investigate whether improving temperature control mechanisms including vascular function, with exercise training is beneficial in alleviating hot flushes in breast cancer patients and their associated quality of life symptoms. Participants will be recruited at least 3-months post breast cancer treatment (surgery, radio-therapy, chemotherapy). This time point has been chosen for this study to allow patients to fully engage in the exercise intervention following treatment. All participants will be asked to attend the laboratory at Liverpool John Moores University on 4 separate occasions; 2 visits pre- and 2 visits following the exercise intervention for data collection including measures of vascular health, physical activity, sedentary behaviour, and fitness. The investigators will also gain information on food intake and incidence of hot flushes across a 7-day period pre- and post the intervention.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Exercise Intervention
Participants will complete a partially supervised 4 month exercise program consisting of 3-5 sessions/week at a moderate intensity (40-75% heart rate (HR) reserve) at Liverpool Lifestyles gyms. Participants will be given free access to the Wellness Key System© when using the Lifestyles exercise equipment which allows researchers to remotely track the exercise intensity of participants accurately.
Behavioral: Exercise Intervention
A partially supervised 16-week moderate intensity exercise intervention consisting of 3-5 sessions per week.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Thermoregulation
Time Frame: Change from pre- to post- 16 week exercise intervention
Participants will wear a tube-lined suit that allows manipulation of skin temperature by heating the water passed through the tubes. Core temperature will be increased by 1 degree (monitored using a temperature pill) with sweat rate and skin temperature recordings taken at 5minute intervals across 1 hour of heating. Thermoregulation will be compared during this hour to that of the post-exercise intervention re-test.
Change from pre- to post- 16 week exercise intervention
Change in Skin Blood Flow
Time Frame: Change from pre- to post- 16 week exercise intervention
The change in skin blood flow will be measured using laser Doppler probes at the forearm.
Change from pre- to post- 16 week exercise intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Cerebral Blood Flow
Time Frame: Change from pre- to post- 16 week exercise intervention
Change in cerebral blood flow will be assessed using transcranial Doppler ultrasound to measure brain blood flow.
Change from pre- to post- 16 week exercise intervention
Change in Vascular Function
Time Frame: Change from pre- to post- 16 week exercise intervention
Vascular function will be measured via endothelial-dependent flow mediated dilation of the brachial artery and reported as a percentage change.
Change from pre- to post- 16 week exercise intervention
Change in Vascular Structure
Time Frame: Change from pre- to post- 16 week exercise intervention
Vascular structure will be measured at the carotid artery using ultrasound imaging to clearly visualise the artery. The image will be adjusted so artery wall thickness can be clearly seen with a 30 second recording taken at 3 different angles. The average of the three angles will be calculated with results reported as change in millimetres.
Change from pre- to post- 16 week exercise intervention
