Cystic FibrosisPhase 2NCT01257464
Sitagliptin in Cystic Fibrosis-Related Diabetes
A Phase 2 study testing Sitagliptin in people with Cystic Fibrosis, run by University of British Columbia at 1 site in Canada.
Trial summary
The purpose of this study is to determine whether the dipeptidyl peptidase IV (DPPIV) inhibitor sitagliptin is effective in the treatment of cystic fibrosis-related diabetes (CFRD). We hypothesize that sitagliptin will improve meal-stimulated insulin secretion. Read more about this study

About this study
Official title: The Effects of the DPPIV Inhibitor Sitagliptin in Cystic Fibrosis-related Diabetes
The purpose of this study is to determine whether the dipeptidyl peptidase IV (DPPIV) inhibitor sitagliptin is effective in the treatment of cystic fibrosis-related diabetes (CFRD). We hypothesize that sitagliptin will improve meal-stimulated insulin secretion.
Read the detailed description
To date, no clinical trials have been conducted using the DPPIV inhibitor sitagliptin in cystic fibrosis-related diabetes. Cystic fibrosis-related diabetes is characterized initially by post-prandial hyperglycemia, with normal fasting sugars. As the disease progresses, fasting hyperglycemia develops. As sitagliptin augments post-prandial insulin release, while avoiding fasting hypoglycemia, it may be an alternative therapy for cystic fibrosis-related diabetes in individuals who do not yet require basal insulin therapy.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.

Also called Januvia, MK-0431, Dipeptidyl peptidase IV inhibitor (DPP-4 inhibitor)
100mg po one dose
PlaceboDrug
Sugar pill po one dose
| Study group | Role | What they receive |
|---|---|---|
| Sitagliptin | Active comparator | Not described Receives: Drug: Sitagliptin |
| Placebo | Placebo comparator | Not described Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Insulin release
The study protocol is a iv-oral hyperglycemic glucose clamp. We will assess insulin release during the clamp, comparing placebo to sitagliptin.
Measured: 180 minutes (during clamp)
Secondary outcomes (1)
Incretin Response
We will assess incretin release [glucoagon-like peptide-1 (GLP-1), gastric inhibitory polypeptide(GIP)] during the glucose clamp.
Measured: 180 minutes (during clamp)

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Sitagliptin in people with Cystic Fibrosis, run by University of British Columbia at 1 site in Canada.
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 2 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: stopped early, as of the sponsor's last update on 6 Mar 2014. 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 Canada. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 was stopped early (reason given: Lack of recruitment). Results are not available in the source record.
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?
Insulin release (time frame: 180 minutes (during clamp)). 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 6 Mar 2014; AzTrials last refreshed its copy on 7 Nov 2026.
