NCT07203378

Brief Summary

The goal of this study is to test the efficacy of using a 12-week, home-based, unsupervised aerobic and resistance training exercise program for changes in cancer-related fatigue in patients with metastatic breast cancer who are receiving Enhertu.

Outcome Measures

Primary Outcomes (1)

  • Change in Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue score from baseline to Week 13 (end of exercise intervention).

    Test the preliminary efficacy of a 12-week, home-based, unsupervised aerobic and resistance training exercise program on changes in cancer-related fatigue, in patients with Metastatic Breast Cancer recently initiated on Enhertu. FACIT Fatigue Scored 0 (not at all)- 4(Very Much).

    13 weeks

Secondary Outcomes (2)

  • Feasibility defined as greater than 75% of all participants completing greater than 66% of all prescribed workouts from baseline to Week 13.

    13 weeks

  • Mean Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue score measured every three weeks from baseline to Week 13.

    13 weeks

Other Outcomes (22)

  • Change in Functional Assessment of Cancer Therapy - Breast (FACT-B) score from baseline to Week 13.

    13 weeks

  • Mean Functional Assessment of Cancer Therapy - Breast (FACT-B) score measured every three weeks from baseline to 13 weeks after initiation of training.

    13 weeks

  • Change in the average time spent in moderate to vigorous physical activity (in minutes)

    12 weeks

  • +19 more other outcomes

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject aged ≥ 18 years
  • Diagnosis of locally advanced/unresectable or metastatic breast cancer. Note: Patients with High-Risk HER-2 + breast cancer after completion of neoadjuvant chemotherapy requiring adjuvant Enhertu are allowed at the discretion of the treating physician.
  • Has received 3 or 4 cycles of Enhertu and is expected to continue treatment for at least 12 weeks. Note: HER-2 targeted systemic therapy (e.g. Trastuzumab and/or Pertuzumab) in conjunction with Enhertu is allowed.
  • Able and willing to participate in the interventional aerobic exercise and resistance exercises.
  • Currently following standard of care contraception requirements and willing to continue following these requirements for the duration of therapy.
  • Able to provide informed consent and willing to sign an approved consent form that conforms to federal and institutional guidelines.
  • Experiencing clinical fatigue symptoms in the opinion of the investigator.
  • Subject has completed the ACSM exercise preparticipation health screening and is, in the opinion of the investigator, fit to participate in this study.

You may not qualify if:

  • Currently adhering to national physical activity guidelines for resistance training, as defined as participating in structured resistance training ≥ two days per week.
  • Structured is defined as time set aside in the subject's day to workout.
  • Resistance training is defined as exercises which use weights, bands, or body weight (e.g., squats or push-ups).
  • AND Currently participating in structured moderate-intensity aerobic exercise for ≥ 150 minutes per week.
  • Moderate-intensity exercise is defined as activities where the subject can talk but not sing.
  • Aerobic exercise includes, but is not limited to, walking, swimming, cycling, running, rowing, hiking, and elliptical.
  • Medical, psychiatric, cognitive, or other conditions that may compromise the participant's ability to understand the participant information, give informed consent, comply with the study protocol or complete the study.
  • Participants taking prohibited medications as described in Section 6.4.1.
