About this study
Official title: Treatment of Dysglycemia Using Sitagliptin in Adolescents With Cystic Fibrosis.
This pilot study will be conducted in adolescents with cystic fibrosis (CF) without diabetes but with abnormal glucose tolerance, and will assess the effects of sitagliptin on glucose regulation. An oral glucose tolerance test (OGTT) and a mixed meal tolerance test (MMTT), will be performed at baseline and again ~4 weeks after treatment with study drug. We will also look at blood sugars throughout the day using a continuous glucose monitor (CGM) before each time the MMTT/OGTT are performed. Several hormones that may affect the way the body regulates blood sugars will be measured in blood when the OGTT and MMTT are done. We will assess the effect this medicine has on blood sugars (using CGM) and the effect the medicine has on the hormones measured during the OGTT and MMTT.

What is being measured
The primary outcome is the main question the study is designed to answer.
Response to sitagliptin
Baseline and stimulated C-peptide levels (using mixed meal tolerance test) before and after treatment with sitagliptin.
Measured: Change from baseline to ~4 weeks of study drug
Response to sitagliptin
Change in glycemic variability using continuous glucose monitoring data before and after treatment with dipeptidyl peptidase-4 inhibitor.
Measured: Change from baseline to ~4 weeks of study drug
Response to sitagliptin
Change in incretins concentrations (glucagon like peptide 1; glucose-dependent insulinotropic polypeptide) in response to study drug.
Measured: Change from baseline to ~4 weeks of study drug
Response to sitagliptin
Change in incretin (glucagon like peptide 1; glucose-dependent insulinotropic polypeptide) concentrations in response to study drug.
Measured: Change from baseline to ~4 weeks of study drug
Secondary outcomes (2)
Beta-cell function
Beta-cell function will be measured using mixed meal tolerance tests (MMTT) and oral glucose tolerance tests (OGTT), assessing maximum concentration and area under the curve (AUC) of glucose, insulin and c-peptide for both OGTT and MMTT.
Measured: Change from baseline to ~4 weeks of study drug
Continuous glucose monitoring (CGM)
Baseline and post-treatment changes in glycemic variability using CGM, including mean amplitude of glycemic excursion (MAGE), peak post-prandial blood sugars, and glucose area under the curve.
Measured: change from baseline to ~4 weeks of study drug

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Sitagliptin in people with Cystic Fibrosis, run by Nemours Children's Clinic at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Response to sitagliptin (time frame: Change from baseline to ~4 weeks of study drug). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jun 2016; AzTrials last refreshed its copy on 8 Nov 2026.
