Investigating the Relationship Between Glycemia and Sleep in Adults With Cystic Fibrosis-Related Diabetes
Investigating the Relationship Between Glycemia and Sleep in Adults With Cystic Fibrosis-Related Diabetes
The goal of this at-home, remote study is to understand the relationship between blood sugars and sleep in adults living with Cystic Fibrosis Related Diabetes (CFRD).
The study is a 10-day home-based, observational study of 30 adults with CFRD aimed at concurrently phenotyping glucose, sleep, and circadian rhythms. The remote study is designed to reduce participant burden while allowing for safe and robust objective data and specimen collection and to inform future clinical trial design. The objective of the proposed pilot and feasibility clinical study is to assess the feasibility of remotely phenotyping glycemia, sleep, and circadian rhythms of adults living with CFRD and to generate preliminary data to power a future clinical trial.
