Continuous glucose monitoring for steroid induced hyperglycemia in breast cancer patients - Clinical Trial

What is the Purpose of this Study?

We are doing this study to find out if the use of continuous glucose monitors (CGMs) is worthwhile to help breast cancer patients and their providers monitor for hyperglycemia, or high blood sugar, during chemotherapy. A CGM is a small, wearable sensor that is attached to the skin to frequently measure your blood sugar level, and can share the measurements to your smartphone and to your medical team.

What is the Condition Being Studied?

Breast Cancer

Who Can Participate in the Study?

Adults ages 18+ who:

  • Are diagnosed with breast cancer (stages I to III)
  • Are starting a chemotherapy regimen that includes a glucocorticoid (e.g., dexamethasone, prednisone, methylprednisolone, or hydrocortisone)
  • Have a body mass index (BMI) greater than 25
  • Are willing to use a Freestyle Libre 3 glucose monitor (provided by the study team) for 8 weeks

Adults

What is Involved?

If you participate in this study, we will ask you to complete surveys before you begin chemotherapy that ask about:

  • Your mood and physical symptoms
  • Your confidence in managing side effects of your treatment
  • What gets in the way of managing your side effects
  • Your interactions with healthcare providers

After you finish the surveys, a member of the study team will teach you how to use the Freestyle Libre 3®, which is an FDA-approved small sensor that is worn on the back of the upper arm and continuously measures your blood sugar.

For a period of 8 weeks, on the first and fifth day of each chemotherapy cycle you receive, you will be asked to complete surveys about your symptoms, side effects, your healthcare experiences, and your experience wearing the CGM.

At the end of 8 weeks, we will interview you about your experience using the CGM and your preferences for monitoring and managing your blood sugar.
