GLP-1 Agonist Therapy for Cystic Fibrosis-related Diabetes
What You Need to Know Before You Apply
What is the purpose of this trial?
Diabetes is a major co-morbidity in pancreatic insufficient cystic fibrosis (PI-CF) and associated with worse outcomes. While reduced β-cell mass contributes to the insulin secretory defects that characterizes cystic fibrosis-related diabetes (CFRD), other modifiable determinants appear operative in the emergence and progression of abnormal glucose tolerance towards diabetes. Identifying interventions to preserve β-cell function are crucial for delaying and potentially preventing CFRD development. In this study, we hypothesize that weekly administration of the long-acting glucagon-like peptide-1 (GLP-1) agonist dulaglutide will improve defective early-phase insulin secretion and improve glucose tolerance during a mixed-meal tolerance test.
Will I have to stop taking my current medications?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are using prandial insulin or repaglinide for diabetes, you may continue these medications during the study.
Is dulaglutide (Trulicity) safe for humans?
How is the drug Dulaglutide unique for treating cystic fibrosis-related diabetes?
What data supports the effectiveness of the drug Dulaglutide (Trulicity) for treating cystic fibrosis-related diabetes?
Dulaglutide (Trulicity) is effective in lowering blood sugar levels in people with type 2 diabetes, and it also helps with weight reduction and reducing the risk of major heart problems. While this data is specific to type 2 diabetes, it suggests potential benefits for managing blood sugar in other conditions like cystic fibrosis-related diabetes.12345
