NCT03988595

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.

Outcome Measures

Primary Outcomes (1)

  • maximum feasible dose (MFD)

    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

Study Arms (5)

aerobic training 90 mins/wk

EXPERIMENTAL

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.

Other: Exercise Treatment

aerobic training 150 mins/wk

EXPERIMENTAL

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.

Other: Exercise Treatment

aerobic training 225 mins/wk

EXPERIMENTAL

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.

Other: Exercise Treatment

aerobic training 300 mins/week

EXPERIMENTAL

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.

Other: Exercise Treatment

aerobic training 375 mins/week

EXPERIMENTAL

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.
