Embr Thermal Device for Hot Flash Management in Prostate Cancer

Feasibility of the Embr Thermal Device for Management of Hot Flashes in Men With Prostate Cancer

This study is being conducted to evaluate if the Embr thermal device is useful for men who experience bothersome hot flashes as a result of prostate cancer treatment.

The Embr thermal device is a smart device that is worn on the inside of the wrist. It is about the size of a smart watch. The Embr thermal device produces cooling or warming temperature sensations that make some people feel slightly cooler or warmer. This objective of this study is to evaluate if the Embr thermal device is useful for men who experience bothersome hot flashes as a result of prostate cancer treatment. The study will take place over 4 weeks. The primary outcome is feasibility of the Embr thermal device in men with prostate cancer. Secondary outcomes include preliminary efficacy of the device, which will include the change in hot flash interference sleep measures (sleep impairment and fatigue). This is a remote study--all study assessments will be completed electronically.
