About this study

Official title: Evaluation of Continuous Glucose Monitoring as a Tool to Measure Glucoregulatory Effects of a Twice Daily Oral Insulin Secretagogue

This trial will attempt to develop the use of Continuous Glucose Monitoring (CGM) as a tool for the evaluation of both new and existing pharmacological treatments for type 2 diabetes, using the twice daily administered dipeptidyl peptidase-4 (DPP4) inhibitor, vildagliptin as a probe. The primary hypothesis is that two weeks of treatment with 50 mg of oral Vildagliptin, twice daily will lead to a statistically significant decrease in 24 hour weighted-mean glucose (WMG) relative to placebo.

Conditions: Type 2 Diabetes Mellitus
Being tested: Vildagliptin, Placebo
Medical subject headings: Diabetes Mellitus, Type 2

What is being measured

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

24 Hour Weighted Mean Glucose (WMG) At 2 Weeks
The 24 hour WMG was measured after 2 weeks of placebo treatment, and again after 2 weeks of vildagliptin treatment. Glucose was measured over a 24 hour period by having participants wear two continuous glucose monitors (CGM), which produced an average glucose value approximately every 5 minutes. Using these values, the concentration of glucose was calculated from Area Under the Curve 0-24 hours (AUC 0-24hr), and was expressed as 24 hour WMG.
Measured: At 2 weeks after Placebo treatment and again at 2 weeks after Vildagliptin treatment

Secondary outcomes (2)

Hemoglobin A1C (HbA1C) At 2 Weeks
Blood samples were taken after 2 weeks of placebo treatment, and again after 2 weeks of vildagliptin treatment to measure the percentage of glycated hemoglobin, HbA1C. Units are therefore presented as HbA1c (%).
Measured: At 2 weeks after Placebo treatment and again at 2 weeks after Vildagliptin treatment
HbA1C At 12 Weeks
Blood samples were taken after 2 weeks of placebo treatment, and again after 12 weeks of vildagliptin treatment to measure the percentage of glycated hemoglobin, HbA1C. Units are therefore presented as HbA1c (%).
Measured: At 2 weeks after Placebo treatment and again at 12 weeks after Vildagliptin treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Vildagliptin 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 2 inclusion and 6 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 19 Aug 2015. 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 Dec 2013). 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?

24 Hour Weighted Mean Glucose (WMG) At 2 Weeks (time frame: At 2 weeks after Placebo treatment and again at 2 weeks after Vildagliptin treatment). 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 NCT01537120.

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 19 Aug 2015; AzTrials last refreshed its copy on 8 Nov 2026.
