Trial summary

The investigators will assess whether the DPP-inhibitor sitagliptin will ameliorate glucocorticoid-induced impairment of glucose metabolism and beta-cell dysfunction and thus could be used as a prophylaxis for glucocorticoid-induced diabetes. Read more about this study

About this study

Official title: Sitagliptin Prophylaxis for Glucocorticoid-Induced Impairment of Glucose Metabolism and Beta-Cell Dysfunction in Males With the Metabolic Syndrome X: A Randomized, Placebo-controlled, Double-blind Intervention Study With a 2x2 Factorial Design

The investigators will assess whether the DPP-inhibitor sitagliptin will ameliorate glucocorticoid-induced impairment of glucose metabolism and beta-cell dysfunction and thus could be used as a prophylaxis for glucocorticoid-induced diabetes. Therefore the investigators will administer in males with the metabolic syndrome 30 mg prednisolone daily for two weeks and give simultaneously sitagliptin 100 mg daily. Subjects will undergo at baseline and after two weeks of treatment several tests to assess changes in glucose metabolism.

Read the detailed description

The investigators will conduct a randomized, placebo-controlled, double-blind, 2x2 factorial-designed intervention trial. The pharmacological intervention for prednisolone/prednisolone-placebo is 14 days and for sitagliptin/sitagliptin-placebo 28 days. Subjects fulfilling the IDF criteria26 for the metabolic syndrome (aged 35-65; n=60) will be randomized to one of four groups: I) prednisolone 30 mg and sitagliptin 100 mg daily; II) prednisolone 30 mg and sitagliptin-placebo daily; III) prednisolone-placebo and sitagliptin 100 mg daily; IV) prednisolone-placebo and sitagliptin-placebo daily. Before and at day 14 of treatment subjects will undergo a standardized mixed-meal test in order to assess glucose disposal and beta-cell function (by modeling analysis). During these meal tests, plasma concentrations of (total and active) GLP-1, GIP, glucagon and additional biomarkers will be assessed. A combined hyperglycemic-euglycemic clamp will be performed at baseline and at day 13 of treatment to assess insulin sensitivity and insulin secretion. During the euglycemic clamp adipose tissue and muscle biopsies will be obtained, both in fasting and under hyperinsulinemic conditions. At baseline and at day 28 of treatment, a 7-point OGTT will be performed to assess time to restoration of glycemic control. Body composition, body fat distribution and liver fat content, measured by respectively bio-impedance analysis and magnetic resonance imaging/spectroscopy (MRI/MRS), will be assessed at baseline and after 28 days of treatment. Blood pressure will be assessed at baseline and after two weeks of treatment. Microvascular function will be assessed with capillary videomicroscopy both at baseline and after two weeks of treatment.

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.

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?

Glucose tolerance as assessed by the area under the curve for glucose (AUCgluc) during a standardized meal test. (time frame: 14 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00721552, which also lists 2 linked publications.

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 2 Jul 2012.
