Brief Summary

Fatigue is a major problem for cancer patients, and one that can persist long after treatment ends. Recent work has demonstrated that light therapy may mitigate or reduce fatigue levels in both cancer patients and cancer survivors. This protocol seeks to assess how lighting interventions distributed through a mobile app affect fatigue, sleep, and quality of life across three populations of cancer patients: breast cancer and prostate cancer, and patients who have undergone autologous hematopoietic stem cell transplant (HSCT). Participants will be randomized 1:1 to either the interventional SYNC app or to a control app.

Outcome Measures

Primary Outcomes (1)

  • Change in Fatigue Assessed With Patient-Reported Outcomes Measurement Information System (PROMIS) Short Form (SF) Fatigue 4a

    The primary outcome was PROMIS® Fatigue 4a Short Form (SF) at the end of trial, compared between arms. As we did not have a PROMIS® 4-item Fatigue weekly measurement for week 0, we were unable to calculate a change from baseline through this measure alone. We assessed this outcome by looking at differences in fatigue between the intervention and control group at the final week (week 11), and the treatment effect on fatigue at week 11 while controlling (through generalized estimating equations) for baseline fatigue with the 1-item Fatigue question ("In the past 7 days, how would you rate your fatigue on average?") taken from the pre-trial PROMIS® Global Health survey. The 1-item question about fatigue on the pre and post-trial Global Health surveys was scored on a scale from 0 (least fatigued) to 4 (most fatigued).

Secondary Outcomes (5)

  • Change in Level of Sleep Disturbance Using PROMIS SF Sleep Disturbance 8a

    baseline to 12 weeks

  • Change in Level of Anxiety Using PROMIS SF Anxiety 7a

    baseline to 12 weeks

  • Change in Level of Depression Using PROMIS SF Depression 8a

    baseline to 12 weeks

  • Change in Level of Physical Function Using PROMIS SF Physical Function 8b

    baseline to 12 weeks

  • Change in Overall Health Metrics Using PROMIS Global-10

    baseline to 12 weeks

Study Arms (2)

Intervention Arm

EXPERIMENTAL

Light intervention delivered through SYNC app + blue-light blocking glasses.

Other: Wearable SensorOther: Blue-blocking glassesOther: Full SYNC app

Control Arm

ACTIVE COMPARATOR

Placebo light intervention delivered through SYNC app + clear glasses.

Other: Wearable SensorOther: Clear glassesOther: "Dummy" SYNC app

Interventions

Patient is given a wearable device to wear for 12 weeks.

Also known as: Apple Watch or Fitbit Charge 3
Control ArmIntervention Arm

Patient is given blue-blocking glasses to wear at instructed times.

Intervention Arm

Patient is given glasses that block no visible light.

Control Arm

Patient downloads the SYNC app and is given light interventions designed to have a targeted, personalized effect on the circadian clock.

Intervention Arm

Patient downloads the SYNC app and is given light interventions designed to have minimal impact on the circadian clock.

Control Arm

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Must own an iPhone 6s or later (with iOS 14 or later or willing to update to iOS 14+) and be willing to complete surveys on it, per the protocol.
  • Sleep aid usage will be allowed as long as the patient has been on a stable dose for at least 4 weeks prior to enrollment and agrees to continue the same dose during the study.
  • A response of at least 4 on a 10 point scale (with 0 = not fatigued at all and 10 = extremely fatigued) to the question "How fatigued did you feel in the past week?"
  • Breast cancer population: Diagnosed with stage 1-3 breast cancer in the last 10 years, without metastatic disease. Chemotherapy or radiation therapy, if indicated, must have been completed at least 3 months prior to enrollment. Concomitant anti-HER2 therapy and/or anti-endocrine therapy is permitted.
  • Prostate cancer population: Undergoing androgen deprivation therapy (ADT) for at least three months and are anticipated to remain on ADT for the duration of the trial. Concomitant additional anti-androgen therapy (e.g., enzalutamide) is permitted.
  • Autologous HSCT population: Participants must be from the University of Michigan Blood and Marrow Transplant Program.

You may not qualify if:

  • The patient cannot be undergoing chemotherapy at the time of enrollment, but post transplant maintenance therapy that begins after enrollment is allowed.
  • The patient must have no evidence of disease progression or recurrence. Specifically for the prostate cancer population, the patient must have no evidence of disease progression on their current ADT regimen at the time of enrollment.
  • The patient must not be a night shift worker, where night shift is defined as working a significant number of hours (i.e. more than half) between the hours of 11PM and 6AM on a regular basis.

Model Details: Blocked randomization will be used to limit bias and achieve an equal distribution of participants to the intervention and control arms of the study (69 control, 69 intervention; with 23 from each cancer population in each arm). This approach will recruit participants in small blocks to ensure that half of the participants within each block will be allocated to the treatment and the other half to the control.
