NCT04473378

Brief Summary

This is a research study to look at blood sugar changes during chemotherapy using a continuous blood sugar monitoring device. The device uses patches that attach to the skin on the back of the arm to measure blood sugar changes for the duration of the chemotherapy course. Each patch lasts for about 2-weeks. During chemotherapy visits, new patches will be placed and will be worn until the chemotherapy course is complete. Participants will be in this study for 6 months. Approximately 50 patients will be enrolled in this study.

Outcome Measures

Primary Outcomes (1)

  • Prevalence of hyperglycemia

    assess the prevalence of HG, defined as the number of participants who have ≥1 glucose value of ≥140 mg/dL at any point during chemotherapy

    24 weeks

Secondary Outcomes (2)

  • Prevalence of impaired glucose tolerance at baseline in nondiabetic patients.

    Baseline

  • Patient-Reported Outcomes Measurement Information System (PROMIS)-29

    Baseline, week 12, and week 24

Study Arms (1)

FreeStyle Libre sensor cohort

Patients with early stage breast cancer will have their blood glucose levels monitored by the Freestyle libre pro sensor.

Device: FreeStyle Libre Pro

Interventions

The device uses patches that attach to the skin on the back of the arm to measure blood sugar changes for the duration of the chemotherapy course.
