June 9, 2025 updated by: Siddartha Angadi, University of Virginia

A Feasibility Study to Examine Two Remotely-monitored Exercise Interventions on Breast Cancer Patients Undergoing Cardiotoxic Chemotherapies

The purpose of this study is to determine if exercise preconditioning can mitigate the off target effects of chemotherapy treatment on measures of cardiovascular function, inflammatory responses, and quality of life.

Detailed Description

Breast cancer is the most common malignancy affecting women in the US and survivors experience long-term health effects of chemotherapy. Exercise training is an efficacious treatment for preserving functional capacity and has shown promise in mitigating cardiac toxicity of breast cancer chemotherapy. However, supervised exercise is not a practical solution for all breast cancer survivors, as medically monitored exercise facilities are poorly dispersed in the US and poorly utilized by cancer patients. To improve reach of these programs, remotely monitoring exercise sessions may be necessary. However, effects of remotely-monitored exercise conditioning before and during adjuvant/neoadjuvant chemotherapy on cardiotoxic outcomes are unknown. Our study aims to address this gap by testing the feasibility of two types of remotely-monitored exercise interventions, an exercise bicycle intervention compared to a brisk walking intervention, in 20 UVA Breast Cancer Clinic patients undergoing cardiotoxic chemotherapies. Remotely-monitored exercise training will start one week prior to chemotherapy (preconditioning) and continue throughout adjuvant or neoadjuvant chemotherapy (which is typically 4 months in duration). Our multidisciplinary research team proposes four aims: 1) Determine the extent to which eligible patients can be successfully recruited, randomized, and retained; 2) Assess VO2peak, echocardiography derived left ventricular ejection fraction and left ventricular global longitudinal strain among these patients at baseline and at ~4 months; 3) Examine treatment engagement and intervention acceptability; and 4) Explore the relationship between engagement in the exercise training and psychosocial function.

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

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: High Intensity Interval Exercise
Subjects will receive a recumbent bike to be delivered and assembled to their home as well as a heart rate monitor and activity tracker. Subjects will undergo high intensity interval exercise 3 days a week, with the goal of achieving 85-90% of their heart rate max. Subjects will also be receiving text messages, phone calls, and emails from study staff to gauge and encourage subject participation and physical activity.
Behavioral: High Intensity Interval Exercise
Patients in the Cycling Intervention arm will undergo two training sessions at the exercise physiology core lab to ensure participants understand the intervention exercise protocol and can safely perform it at home. The Participants will perform high intensity interval training (HIIT) 3 days per week, with each session consisting of four, 4-min intervals at 85-90% peak heart rate (PHR), separated by 3 min at 50% PHR. Each training session will begin with a 10-minute warm-up at 50% of PHR and end with a 5-min cool down at 50% PHR. Subjects will then perform this exercise training at their own homes using recumbent exercise bikes provided by the investigators for that purpose. Study investigators will check in up to weekly with participants and remotely track exercise data and compliance via activity tracker.
Experimental: Moderate Intensity Walking
Subjects allocated to moderate intensity walking will be given a gift card to purchase a paid of running shoes. A chest-based heart rate monitor and an activity tracker watch will be provided. Subjects will aim to achieve 150 minutes a week of moderate intensity walking. Subjects will also be receiving text messages, phone calls, and emails from study staff to gauge and encourage subject participation and physical activity.
Behavioral: Moderate Intensity Walking
Patients will undergo two familiarization training sessions in the exercise physiology core lab to ensure participants understands the walking intervention and can properly gauge intensity. Participants will be asked to walk briskly or jog so they achieve a moderate intensity (70-75% of the maximal heart rate achieved during the VO2peak test). The goal for participants in this condition will be to accumulate at least 150-minutes per week at this heart rate by brisk walking or jogging. Participants will also receive a gift card to be used to purchase a pair of walking shoes to facilitate their engagement.
