Semaglutide in CFRD

University of Minnesota8 enrolled

Overview

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).

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

Outcomes

Primary Outcomes

Weight

Change in weight before and 12 weeks post treatment

Time frame: 12 weeks

BMI (kg/m2)

Change in BMI before and 12 weeks post treatment

Time frame: 12 weeks

Secondary Outcomes

CGM % Time in Target TIR)

Change in CGM TIR before and 12 weeks post treatment. Outcome reflects the change in continuous glucose monitoring (CGM) time in range (TIR), measured at baseline and again 12 weeks after treatment initiation. TIR is defined as the percentage of time glucose values are between 70 and 180 mg/dL

Time frame: 12 weeks

A1c

change in the percent of HbA1c before and 12 weeks post treatment

Time frame: 12 weeks
