Cystic Fibrosis study: GLP-1 vs GIP

Official title Beta-cell Response to Incretin Hormones in Cystic Fibrosis

ClinicalTrials.gov ID: NCT01851694

What this study is testing

What is GLP-1?

This is an investigational infusion being studied to help understand and potentially treat diabetes in people with cystic fibrosis. It is designed to help the body make more insulin to manage blood sugar levels.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study aims to learn how cystic fibrosis–related diabetes develops and whether a hormone that increases insulin can help.
Who it's for
People with cystic fibrosis, including those with diabetes or normal blood sugar, and a small group of people without cystic fibrosis.
What's involved
Participants will receive the hormone and have blood tests and other routine visits to see how their bodies respond.
  • You might receive a placebo (an inactive treatment) instead of the study drug.

Who can take part

Ages 18 and older. Healthy volunteers may be eligible.

You may be able to join if

  • Confirmed diagnosis of cystic fibrosis, defined by positive sweat test or CFTR mutation analysis according to CFF diagnostic criteria,
  • Age greater than or equal to 18y on date of consent
  • Pancreatic insufficiency
  • Recent OGTT consistent with Indeterminate-GT, IGT, CFRD w/o fasting hyperglycemia, or an established diagnosis of CFRD without fasting hyperglycemia
  • No history of cystic fibrosis.

You likely can't join if

  • Established diagnosis of non-CF diabetes (i.e. T1D) or CFRD with fasting hyperglycemia (fasting glucose greater than126 mg/dL)
  • History of clinically symptomatic pancreatitis within last year
  • Prior lung or liver transplant
  • Severe CF liver disease, as defined by portal hypertension
  • Fundoplication-related dumping syndrome
  • Medical co-morbidities that are not CF-related or are unstable per investigator opinion (i.e. history of bleeding disorders, immunodeficiency)
