Study summary

The purpose of this study is to examine which of four components of a digital health intervention using an App and Fitbit meaningfully contribute to increased physical activity in Metastatic Breast Cancer Patients.

Participants will be asked to:

  • Wear a Fitbit and use an app, use 0 to 3 other components for 24 weeks and attend 6 or 12 coaching coaching calls in the first 12 weeks to increase daily steps.
  • Complete a questionnaire at baseline, week 12 and week 24
  • Complete functional performance test (FPT) via Zoom at baseline, week 12 and week 24
  • Wear a research activity monitor (Accelerometer) for 7 days at baseline, week 12 and week 24
Read the detailed description

Multiphase Optimization Strategy (MOST) methodology will be used to determine which intervention components or component combinations optimally increase daily steps in a 12-week intervention with a 12-week follow-up. MOST is a framework adapted from engineering that uses highly efficient factorial experiments to evaluate individual, and combined, effects of intervention components to determine which ones can be reduced, eliminated, or replaced to improve efficiency. Insufficiently active people with metastatic breast cancer (MBC) will receive a core intervention consisting of the FIt2ThriveMB app and Fitbit and be randomly assigned to four components, each with two-levels, under consideration for inclusion in the optimized intervention: 1) EHR-integration (on v. off); 2) coaching dose (weekly v. bi-weekly; 3) social+ (on v. off) and 4) goal-setting type (highly tailored v. static). The effects of increasing PA on symptom burden, other intensity activities (i.e. moderate to vigorous, light and sedentary), and functional performance and potential mediators and moderators of component effects will also be examined. Knowledge gained from this study will inform the development of more effective and scalable interventions to improve health and disease outcomes in this population.

Interventions

  • BehavioralCore Intervention

    The core intervention includes educational materials, Fitbit and access to the Fit2ThriveMB Core App.

  • BehavioralEHR Integration (On v. Off)

    Participant Fitbit data will synchronize with the EHR. Participants will receive automated weekly messages via the patient portal. Clinicians can view patient Fitbit data and will receive Epic InBasket messages on the day of patient appointments with a summary of patients' PA progress and talking points to encourage patients.

  • BehavioralWeekly Coaching

    Participants will receive 12 calls from study staff to provide feedback on PA progress and support to increase PA.

  • BehavioralSocial+ (on v. off)

    Participants assigned to this condition will receive the social feed app module and attend 7 synchronous, facilitated group sessions during the 12-week intervention. There will also be a social feed app module is intended to enhance communication and support among participants.

  • BehavioralStatic Goal Setting

    Participants will be provided with a daily step goal for the week. The goal will be progressive and tailored to each individual's progress to build efficacy and ensure safe progression until 10,000 steps/day is achieved (i.e. 4500 steps/day in week 1, 5500 steps/day in week 2, etc.).

  • BehavioralBi-Weekly Coaching

    Participants will receive 6 calls from study staff to provide feedback on PA progress and support to increase PA.

  • BehavioralHighly Tailored Goal Setting

    Participants will be prompted each morning to report the intensity of their symptom burden on a scale from 1 to 5. Based on symptom rating, prior day's step goal attainment and/or the number of steps achieved the previous day, participants will be provided with three to four goal options for that day.

What researchers measure

Primary outcomes

  1. Change in Steps

    The ActiGraph accelerometer will be used. Participants will wear the device during all waking hours for 7 consecutive days, except when bathing or swimming, on their non-dominant hip.

    Time frame: Baseline, 12 and 24 weeks

Secondary outcomes

  1. ActiGraph measured MVPA

    Moderate to vigorous physical activity will be measured using the ActiGraph. Participants will wear the device during waking hours for 7 consecutive days, except when bathing or swimming, on their non-dominant hip. Freedson cut points will be used to determine this activity as 2,690-9,642 CPM.

    Time frame: Baseline, 12 and 24 weeks

  2. ActiGraph measured light activity

    Light intensity physical activity will be measured using the ActiGraph. I Participants will wear the device during waking hours for 7 consecutive days, except when bathing or swimming, on their non-dominant hip. Freedson cutpoints for light activity are defined as Light: 0 - 2,689 CPM.

    Time frame: Baseline, 12 and 24 weeks

  3. ActiGraph measured sedentary behavior

    Sedentary behavior will be measured using the ActiGraph. Participants will wear the device during waking hours for 7 consecutive days, except when bathing or swimming, on their non-dominant hip. Freedson cutpoints for sedentary behavior are defined as \<100 CPM.

    Time frame: Baseline, 12 and 24 weeks

  4. Godin Leisure Time Exercise Questionnaire

    Participants will be asked to indicate frequency of participation in strenuous (e.g., jogging), moderate (e.g., fast walking), and mild (e.g., easy walking) exercise over the past 7 days and average time spent in each activity. Activity frequencies will be multiplied by 9, 5, and 3 metabolic equivalents, respectively, and summed to create a total leisure time activity score. Weekly minutes of total, light, moderate, and vigorous activity will be calculated by multiplying the frequency and time of each activity. This value will be divided by 7 to obtain daily averages.

    Time frame: Baseline, 12 and 24 weeks

  5. Short Physical Performance Battery (SPPB) Total Score

    The SPPB score is based on timed measures of gait speed, ability to rise from a chair, and standing balance. Gait speed will be measured using the better of two recorded times over a 4-meter course. Chair stand time will be measured as the time needed to rise five times from a seated position in a chair, with arms folded across the chest. For the balance test, participants will be asked to maintain their feet side-by-side, semi-tandem, and tandem positions for 10 seconds each. Each individual performance measure will be scored according to established cut points and aggregated for a total SPPB score.

    Time frame: Baseline, 12 weeks, 24 weeks

  6. PROMIS Physical Function

    PROMIS-29 (Patient-Reported Outcomes Measurement Information System 29-item Profile) will be used to measure physical function with 4 items over the past 7 days. Items are combined using a t-score metric where higher score is better.

    Time frame: Baseline, 12 and 24 weeks

  7. PROMIS Anxiety

    PROMIS-29 (Patient-Reported Outcomes Measurement Information System 29-item Profile) will be used to measure Anxiety with 4 items over the past 7 days. Items are combined using a t-score metric where the lower score is better.

    Time frame: Baseline, 12 and 24 weeks

  8. PROMIS Depression

    PROMIS-29 (Patient-Reported Outcomes Measurement Information System 29-item Profile) will be used to measure Depression with 4 items over the past 7 days. Items are combined using a t-score metric where the lower score is better.

    Time frame: Baseline, 12 and 24 weeks

  9. PROMIS Fatigue

    PROMIS-29 (Patient-Reported Outcomes Measurement Information System 29-item Profile) will be used to measure Fatigue with 4 items over the past 7 days. Items are combined using a t-score metric where the lower score is better.

    Time frame: Baseline, 12 and 24 weeks

  10. PROMIS Ability to Participate in Social Roles and Activities

    PROMIS-29 (Patient-Reported Outcomes Measurement Information System 29-item Profile) will be used to measure Ability to Participate in Social Roles and Activities with 4 items over the past 7 days. Items are combined using a t-score metric where the higher score is better.

    Time frame: Baseline, 12 and 24 weeks

  11. PROMIS Sleep Disturbance

    PROMIS-29 (Patient-Reported Outcomes Measurement Information System 29-item Profile) will be used to measure sleep disturbance with 4 items over the past 7 days. Items are combined using a t-score metric where the lower score is better.

Timeline

2 registry updates since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jan 2027; primary completion for Jan 2031, 48 months later.

Of 2,661 non-industry interventional studies with no phase under Breast Neoplasms, half reached primary completion within 33 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 66. This study's planned 48 months is above that.

Counting every sponsor, half of 2,771 studies reached it within 33 months; a quarter within 15 and three quarters within 66.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
