• Conditions: Breast Cancer
• Interventions: Behavioral: Aerobic Training; Behavioral: Educational Information; Behavioral: Supervised Home Based Training

• Registration Number: NCT01943695
• Lead Sponsor: Memorial Sloan Kettering Cancer Center

Brief Summary

The purpose of this study is to compare the effects of aerobic exercise training during and after chemotherapy for women who have recently been diagnosed with early-stage breast cancer.

The participant will be instructed to self-report the session information to ExOnc staff at or before their next scheduled visit. If the participant's next scheduled visit is greater than 72 hours following an unsupervised session, ExOnc staff may reach out to the participant to retrieve the session information. Unsupervised session details will be source documented by ExOnc staff.

Arm && Interventions

Group	Intervention	Description
Aerobic Training During Chemotherapy	Aerobic Training	The ultimate goal is for participants to complete approximately 3 exercise sessions week of non-linear aerobic training an intensity of at 55% to 100% of the individually determined exercise capacity VO2peak), concurrent with chemotherapy. VO2peak will be determined by the CPET performed at baseline. The weekly exercise will be achieved via 3 individual aerobic training sessions ranging from approximately 20-45 min/session. All sessions are required to be supervised unless otherwise specified by EP discretion.
Aerobic Training After Chemotherapy	Aerobic Training	The ultimate goal is for participants to complete approximately 3 exercise sessions week of non-linear aerobic training at an intensity 55% to 100% of the individually determined exercise capacity (VO2peak), after the completion of chemotherapy. VO2peak will be determined by the CPET performed at midpoint, or pre-surgery for neoadjuvant patients. For patients receiving adjuvant therapy, (except those who have additional surgery after chemotherapy), the aerobic training intervention must begin within 2 weeks of the patient's midpoint CPET. For patients receiving neoadjuvant or adjuvant therapy and have additional surgery after chemotherapy, the aerobic training intervention will begin within approximately 6 weeks of surgery, per the discretion of the treating physician. The weekly exercise will be achieved via 3 individual aerobic training sessions ranging from approximately 20-45 min/session. All sessions are required to be supervised unless otherwise specified by EP discretion.
General Physical Activity Group	Supervised Home Based Training	Patients will receive a home-based, general physical activity program. Specifically, all patients assigned to general physical activity will receive an initial, consultation with a staff exercise physiologist outlining a structured home-based aerobic walking program with a goal up to 150 minutes per week outside of their normal daily activity. Patients can be provided with a fitness tracker (e.g. FitBit) to evaluate exercise duration and intensity. Patients may also be provided with an exercise log to record type, duration, and average heart rate during sessions. The exercise log is provided as a guidance tool and may be, although is not required to be, returned to study staff. Staff exercise physiologists will contact patients to check progress, and answer questions.
Continuous Aerobic Training	Aerobic Training	The ultimate goal is for participants to complete 3 exercise sessions week of non-linear aerobic training at 55% to 100% of the individually determined exercise capacity (VO2peak), during and after chemotherapy. For patients receiving adjuvant therapy (except those who have additional surgery after chemotherapy), VO2peak will be determined by the CPETs performed at baseline and midpoint. For patients receiving neoadjuvant or adjuvant therapy and have additional surgery after chemotherapy, VO2peak will be determined by the CPETs or at baseline, pre- surgery, and post-surgery. The weekly exercise will be achieved via 3 individual aerobic training sessions ranging from approximately 20-45 min/session. All sessions are required to be supervised unless otherwise specified by EP discretion.

Primary Outcome Measures

Name	Time	Method
Change in VO2 peak (functional capacity)	during chemotherapy 3-6 months depending on treatment recommendations	To determine the optimal timing of aerobic activity, relative to an attention-control group, on exercise capacity in a breast cancer setting. This will be evaluated using an electronic motorized treadmill test with 12-lead ECG monitoring (Mac® 5000, GE Healthcare) performed by certified exercise physiologists.

Secondary Outcome Measures

Name	Time	Method
Physical activity recall during and after Chemotherapy	at baseline, mid-point (12 weeks approximately) , and follow-up (24 weeks approximately) testing	Determine the effects on patient-reported outcomes. Time frame can vary based on individual length of chemotherapy.
Sleeping patterns as measured by questionnaire during and after Chemotherapy	at baseline, mid-point (12 weeks approximately) , and follow-up (24 weeks approximately) testing	Determine the effects on patient-reported outcomes. Time frame can vary based on individual length of chemotherapy.
Skeletal Muscle Function	at baseline, mid-point (12 weeks approximately) , and follow-up (24 weeks approximately) testing	To examine the physiological mediators of the exercise training - exercise capacity relationship (e.g., skeletal muscle function as assessed by a muscle biopsy)performed.
Quality of Life measured by questionnaire during and after Chemotherapy	at baseline, mid-point (12 weeks approximately) , and follow-up (24 weeks approximately) testing	Determine the effects on patient-reported outcomes. Time frame can vary based on individual length of chemotherapy.
Depression scale during and after Chemotherapy	at baseline, mid-point (12 weeks approximately) , and follow-up (24 weeks approximately) testing	Determine the effects on patient-reported outcomes. Time frame can vary based on individual length of chemotherapy.
