About this study

Official title: A Randomized Clinical Trial to Evaluate Glucose-Dependent Insulinotropic Effects of a Single Dose of a DPP-4 Inhibitor in Lean Healthy Males

This study will evaluate the effect of a single dose of sitagliptin on glucose dependent insulin secretion using a meal tolerance test (MTT) during a hyperglycemic clamp (HCG) procedure.

Being tested
sitagliptin, Comparator: Placebo
Medical subject headings
Diabetes Mellitus, Type 2

What participants receive

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

  • sitagliptinDrug

    Also called sitagliptin phosphate, MK0431

    Single oral dose of sitagliptin 100 mg (2 x 50 mg) tablets followed by the hyperglycemic clamp procedure and meal tolerance test.

  • Comparator: PlaceboDrug

    Single oral dose of 2 tablets placebo to sitagliptin followed by the hyperglycemic clamp procedure and meal tolerance test.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Insulin Secretion Rate (ISR) During 190 - 340 Minutes Post-dose

    ISR was estimated by the deconvolution of peripheral C-peptide concentrations using a 2-compartment model that utilizes population C-peptide kinetic parameters.

    Measured: 190 minutes to 340 minutes

Secondary outcomes (1)
  1. Glucose Infusion Rate (GIR) During 190 - 340 Minutes Post-dose

    Glucose Infusion Rate required to maintain the target glucose level of 160 milligrams / deciliter (mg/dL) ; GIR was normalized to subject's body weight (kg).

    Measured: 190 minutes to 340 minutes

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing sitagliptin in people with Type 2 Diabetes Mellitus, run by Merck Sharp & Dohme LLC.

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 4 inclusion and 5 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 26 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 3 Aug 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Secretion Rate (ISR) During 190 - 340 Minutes Post-dose (time frame: 190 minutes to 340 minutes). 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 NCT00888238, which also lists 1 linked publication.

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 26 Jun 2018.
