Could a sticky patch replace the sugar drink test for cystic fibrosis diabetes?
NCT ID NCT06560463
First seen Jun 26, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This study compares a continuous glucose monitor (CGM) worn on the skin to the standard oral glucose tolerance test (OGTT) for detecting diabetes in adults with cystic fibrosis. The OGTT is time-consuming and often skipped, so researchers want to see if the CGM is a simpler and equally effective alternative. Thirty adults with normal or mildly abnormal glucose tolerance will wear the CGM for 10 days and also undergo the standard test.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could make diabetes screening for people with cystic fibrosis easier and more convenient, potentially improving early detection and health outcomes.
- What could go wrong
- This is a small, early-stage study with only 30 participants. The CGM may not be as accurate as the standard test, and results may not apply to all people with cystic fibrosis.
