About this study

Official title: A Phase 2/3, Double-Blind, Randomized, Placebo-Controlled, Parallel-Group, Multicenter Study to Determine the Efficacy and Safety of SYR-322 When Used in Combination With Sulfonylurea in Subjects With Type 2 Diabetes in Japan

The purpose of this study was evaluate the efficacy and safety of alogliptin, once daily (QD) combined with an Sulfonylurea taken QD or twice daily (BID) in type 2 diabetic patients with uncontrolled blood glucose.

Read the detailed description

Both insulin hyposecretion and insulin-resistance are considered to be involved in the development of type 2 diabetes mellitus.

Takeda is developing SYR-322 (alogliptin) for the improvement of glycemic control in patients with type 2 diabetes mellitus. Alogliptin is an inhibitor of the dipeptidyl peptidase IV (DPP-IV) enzyme. DPP-IV is thought to be primarily responsible for the degradation of 2 peptide hormones released in response to nutrient ingestion. It is expected that inhibition of DPP-IV will improve glycemic control in patients with type 2 diabetes.

The present study was planned to evaluate the efficacy and safety of alogliptin as an add-on to sulfonylurea in type 2 diabetic patients who had uncontrolled blood glucose despite treatment with an sulfonylurea as well as diet and exercise therapies.

What is being measured

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

  1. Change From Baseline in Glycosylated Hemoglobin (Week 12).

    The change in the value of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at week 12 or final visit and glycosylated hemoglobin collected at baseline.

    Measured: Baseline and Week 12.

Secondary outcomes (8)
  1. Change From Baseline in Glycosylated Hemoglobin (Week 2).

    The change in the value of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at week 2 and glycosylated hemoglobin collected at baseline.

    Measured: Baseline and Week 2.

  2. Change From Baseline in Glycosylated Hemoglobin (Week 4).

    The change in the value of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at week 4 and glycosylated hemoglobin collected at baseline.

    Measured: Baseline and Week 4.

  3. Change From Baseline in Glycosylated Hemoglobin (Week 8).

    The change in the value of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at week 8 and glycosylated hemoglobin collected at baseline.

    Measured: Baseline and Week 8.

  4. Change From Baseline in Fasting Plasma Glucose (Week 2).

    The change between the value of fasting plasma glucose collected at week 2 and baseline.

    Measured: Baseline and Week 2.

  5. Change From Baseline in Fasting Plasma Glucose (Week 4).

    The change between the value of fasting plasma glucose collected at week 4 and baseline.

    Measured: Baseline and Week 4.

  6. Change From Baseline in Fasting Plasma Glucose (Week 8).

    The change between the value of fasting plasma glucose collected at week 8 and baseline.

    Measured: Baseline and Week 8.

  7. Change From Baseline in Fasting Plasma Glucose (Week 12).

    The change between the value of fasting plasma glucose collected at week 12 or final visit and baseline.

    Measured: Baseline and Week 12.

  8. Change From Baseline in Blood Glucose Measured by the Meal Tolerance Test (Week 12).

    The change between the value of blood glucose measured by the meal tolerance test collected at week 12 or final visit and blood glucose measured by the meal tolerance test collected at baseline. Meal tolerance test measures blood glucose through blood samples drawn before a meal and at 2 hours after the start of the meal.

    Measured: Baseline and Week 12.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Alogliptin and glimepiride and Glimepiride in people with Type 2 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 5 inclusion and 1 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 6 Jul 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 (Week 12). (time frame: Baseline and Week 12.). 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 NCT01318083, 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.
