Smart insulin pump could ease diabetes in cystic fibrosis patients
NCT ID NCT05562492
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a hybrid closed-loop system (CamAPS FX) can improve blood sugar control in people aged 16 and older with cystic fibrosis-related diabetes. The system combines an insulin pump, continuous glucose monitor, and smartphone app to automatically adjust insulin. Over 26 weeks, researchers will compare this approach to standard insulin therapy with glucose monitoring in 128 participants.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CamAPS FX hybrid closed-loop system (insulin pump, continuous glucose monitor, and smartphone app)
- What this could lead to
- If successful, this could offer a more automated and effective way to manage blood sugar in cystic fibrosis-related diabetes, potentially reducing complications and improving quality of life.
- What could go wrong
- This is a relatively small, early-stage trial (128 participants) and the technology may not work for everyone. There are risks of device malfunction or hypoglycemia, and the system requires 24/7 wear and training.
