Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This open label, single arm pilot study, will examine the safety and tolerability of GLP-1RA semaglutide as an add-on therapy to insulin for overweight/obese adult patients with cystic fibrosis related diabetes (CFRD).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The overall goal of this proposal is to collect pilot data for safety and feasibility metrics to support a future larger randomized controlled trial. In this study, we will examine the safety and tolerability of GLP-1RA semaglutide as an add-on therapy to insulin for overweight/obese adult patients with CFRD. We hypothesize that weekly administration of the long-acting GLP-1RA semaglutide to overweight/obese CFRD patients will be safe and well tolerated.

Specific Aim 1: Collect pilot data on the safety and feasibility of weekly semaglutide therapy in overweight and obese patients with CFRD to support a future larger randomized controlled trial.

Hypothesis 1: Weekly therapy with GLP-1RA semaglutide will be safe and well tolerated in overweight/obese adults with CFRD.

Specific Aim 2: Collect preliminary data to examine the impact of semaglutide therapy on insulin secretion, glucagon and glucose levels as measured by oral glucose tolerance test (OGTT), and on glycemic outcomes as measured by continuous glucose monitoring (CGM) and HbA1c.

Hypothesis 2a: Treatment with semaglutide will lower glucose levels, and increase insulin and C-peptide area under the curve (AUC) during the OGTT as compared to baseline.

Hypothesis 2b: Treatment with semaglutide will improve glycemic control as indicated by time in range on CGM and HbA1c
