Exercise Treatment With Standard Therapy for Metastatic Breast Cancer

August 26, 2025 updated by: Memorial Sloan Kettering Cancer Center

Phase 1 Trial of Exercise Treatment With Concurrent First-Line Therapy for Hormone Receptor Positive Metastatic Breast Cancer

This study will test any good and bad effects of aerobic exercise performed while you are receiving the usual first-line treatment for metastatic breast cancer. The researchers think that exercise helps delay the development of resistance to hormone therapy while slowing the growth of tumors.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: aerobic training 90 mins/wk
Exercise sessions will consist of individualized, walking delivered following a non-linear(i.e., exercise intensity is continually altered and progressed in conjunction with appropriate rest/recovery sessions across the entire intervention period) dosing schedule up to 7 individual treatment sessions/wk for 6 months. Remote supervised exercise sessions will be implemented and monitored using TeleEx. General physical activity as well as exercise performed outside of the structured treatment sessions will be evaluated via continuous monitoring using MSK approved telemedicine / wireless technology.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
maximum feasible dose (MFD)
Time Frame: 24 weeks
Feasibility is defined in terms of the relative dose intensive (RDI), the proportion of the planned exercise prescription that was completed without requiring a dose modification or interruption. The MFD is defined as the dose estimated to result in approximately 70% of patients achieving an RDI ≥ 75%.
24 weeks
