Hormone Receptor Positive Metastatic Breast Cancer

Keywords
Exercise, 19-113
Brief summary
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.
Interventions
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.

Intervention model description
Exercise therapy will consist of individualized walking delivered 3 to 5 times weekly for 24 weeks. This trial will evaluate four escalated doses of exercise (90 mins/wk, 150 mins/wk, 225 mins/wk, 300 mins/week, or 375 mins/week).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| maximum feasible dose (MFD) | 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%. |
