About this study

Official title: A Randomized, Double-Blind, Comparator-Controlled Study of Pioglitazone HCl vs Glyburide in the Treatment of Patients With Type 2 (Non-Insulin-Dependent) Diabetes Mellitus and Mild Cardiac Disease (NYHA I)

The purpose of this study is to evaluate the cardiovascular effects of pioglitazone, once daily (QD), versus glyburide when administered to patients with type 2 diabetes mellitus and mild cardiac disease.

Read the detailed description

Diabetes is a chronic disease involving multiple metabolic defects that include inadequate insulin activity and resultant hyperglycemia. Individuals' differing genetic predisposition, level of physical activity, and age all contribute to variations in the onset and severity of type 2 diabetes. However, progression of this disease typically follows a characteristic pattern that begins as a reduced sensitivity of hepatic and peripheral-tissues to circulating insulin (ie, insulin resistance). The body's decreasing ability to produce adequate insulin to overcome insulin resistance (ie, insulin deficiency due to beta-cell insufficiency) results in impaired glucose tolerance and ultimately overt diabetes. In the United States, an estimated 17 million people have diabetes, with type 2 diabetes occurring in approximately 90% to 95% of cases.

The goal of treating type 2 diabetes is to control blood glucose and thereby prevent long-term complications. Adequate glycemic control is paramount in attempting to avert chronic complications, including blindness, renal dysfunction and resultant dialysis or renal transplantation, neuropathy, and nontraumatic amputations. Intensive glucose management in the early stages of diabetes may help forestall complications.

Pioglitazone is a thiazolidinedione developed by Takeda Chemical Industries, Ltd. Glyburide, is an oral antidiabetic agent of the sulfonylurea class. The primary purpose of this study is to evaluate the cardiovascular effects of pioglitazone versus glyburide when administered to patients with type 2 diabetes mellitus and mild cardiac disease

Study participation is anticipated to be approximately 1 year and 2 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Pioglitazone and Glyburide 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 7 inclusion and 36 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 28 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 phase mean?

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?

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?

Change in the walking distance during a standardized 6-minute walk test. (time frame: Weeks 2, 16, 24, 40, and 52 or Final Visit). 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 NCT00521742, 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 28 Feb 2012.
