About this study

Official title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled Comparison Study to Determine the Efficacy and Safety of SYR110322 in Patients With Type 2 Diabetes, Who Are Either Receiving No Current Treatment or Currently Treated With Diet and Exercise, Sulfonylurea, Metformin or a Combination of Sulfonylurea and Metformin

The purpose of this study is to determine the safety and efficacy of alogliptin, once daily (QD), compared to diet and exercise, sulfonylurea, metformin and a combination of sulfonylurea and metformin for treating subjects with type 2 diabetes.

Read the detailed description

Of the approximately 19 million people in the United States who have been diagnosed with diabetes mellitus, 90% to 95% have type 2 diabetes mellitus. The prevalence of type 2 diabetes mellitus varies among racial and ethnic populations and has been shown to increase with age, obesity, family history, history of gestational diabetes, and physical inactivity. Over the next decade, a disproportionate increase in the elderly population will result in a marked increase in diabetic patients, placing an ever-increasing burden on families and the health care system.

In response to this problem, Takeda Global Research \& Development Center, Inc. is developing SYR-322 (alogliptin), a selective, orally available inhibitor of the enzyme dipeptidyl peptidase IV. Dipeptidyl peptidase IV is thought to be primarily responsible for the in vivo degradation of 2 peptide hormones released in response to nutrient ingestion, namely glucagon-like peptide-1 and glucose-dependent insulinotropic peptide.

Individuals who want to participate in this study will be required to provide written informed consent. Study participation is anticipated to be about 14 Weeks. Multiple procedures will occur at each visit which may include blood collection, urine collection, vital signs including sitting and standing blood pressure and pulse, body height and weight, physical examinations and electrocardiograms.

    The incidence of marked hyperglycemia occurring in participants with a fasting plasma glucose value greater than or equal to 200 mg per dL during study. Overall mean obtained by weighting the hyperglycemia percent incidence values at each time point by number of days in between visits.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Alogliptin in people with Diabetes Mellitus, run by Takeda.

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 22 inclusion and 15 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 3 Feb 2012. 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. 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?

Yes. Results are posted in the registry (first posted 29 Aug 2011). 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?

Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Day 85. (time frame: Baseline and Day 85.). 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 NCT00755846, 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 3 Feb 2012; AzTrials last refreshed its copy on 7 Nov 2026.
