About this study

This study will investigate the effects of rosiglitazone, a medicine commonly used to treat type 2 diabetes, on the utilization of glucose by the heart in patients with heart failure which is not due to heart attacks. The primary purpose of the study is to determine whether treatment with an insulin-sensitizing medication will improve the heart's ability to metabolize glucose (sugar).

Read the detailed description

Nondiabetic patients with nonischemic cardiomyopathy who are insulin-resistance or insulin-sensitive based on a fasting homeostasis model assessment (HOMA) value are eligible for the trial. At baseline, a 6-minute walk test is performed, followed by assessment of coronary flow reserve with ammonia-PET imaging before/after adenosine infusion. Subjects are then given an oral glucose load (75g), followed by PET imaging with F-18-fluoro-2-deoxyglucose (FDG). Subjects then begin taking rosiglitazone 4 mg qd x 12 weeks, after which the 6-minute walk test \& PET imaging is repeated.

What is being measured

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

  1. Myocardial glucose uptake (intrasubject before/after rosiglitazone)

  2. Myocardial glucose uptake (between insulin-resistant & insulin-sensitive groups)

Secondary outcomes (2)
  1. Coronary flow-reserve

  2. 6-minute walk time

Questions about this trial

What is this clinical trial studying?

A study testing Rosiglitazone therapy in people with Dilated Cardiomyopathy, run by Stanford University at 1 site in United States.

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 14 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: stopped early, as of the sponsor's last update on 13 May 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

Are results available for this study?

The study was stopped early (reason given: concern over safety of rosiglitazone in heart failure). Results are not available in the source record.

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?

Myocardial glucose uptake (intrasubject before/after rosiglitazone). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 13 May 2014.
