Summary

This trial is testing whether using a CGM to help calculate meal-time insulin doses leads to better blood sugar management for people with CF than the current standard method.

Who is the study for?
This trial is for adults over 18 with cystic fibrosis-related diabetes, including those who've had a lung transplant and are on basal bolus insulin therapy. It's not open to current CGM users or those unable to perform fingerstick blood sugar tests.
What is being tested?
The study compares two ways of dosing meal-time rapid-acting insulin in cystic fibrosis patients: calculating doses based on carbohydrate intake versus using fixed doses. The effectiveness will be measured using continuous glucose monitors.
What are the potential side effects?
Potential side effects may include low blood sugar (hypoglycemia) from incorrect insulin dosing, which can cause shakiness, sweating, confusion, and in severe cases, loss of consciousness.

He was phenomenal. Not only did he listen to my issues, but he provided additional resources and called me back to review my lab results.
