Fitbits and glucose monitors tested for exercise tracking in cancer and diabetes patients
NCT ID NCT05124405
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether people with cancer or diabetes can use a Fitbit and a continuous glucose monitor (CGM) to track their daily exercise and glucose levels. The goal is to see if it's practical and if people will stick with it. Thirty-five participants will wear both devices for a period of time, and researchers will measure how many people agree to join and how well they follow the monitoring plan.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Fitbit and continuous glucose monitor (CGM)
- What this could lead to
- If successful, this could show that wearable devices are a practical way to monitor physical activity and glucose levels in people with cancer or diabetes.
- What could go wrong
- This is a very small feasibility study with only 35 participants. It is not designed to test health outcomes, only whether people will use the devices as instructed.
