Trial summary

Cardiovascular disease is the leading cause of death in diabetic patients due to both a high event rate and a worse outcome. A pharmacological intervention that reduces ischemia-reperfusion-injury would improve the outcome of diabetic patients after a cardiovascular event. Read more about this study

About this study

Official title: The Effect of Rosiglitazone on Ischemia-reperfusion-injury Using Annexin A5 Scintigraphy. A Double Blind Placebo- Controlled Cross-over Study in Subjects With the Metabolic Syndrome

Cardiovascular disease is the leading cause of death in diabetic patients due to both a high event rate and a worse outcome. A pharmacological intervention that reduces ischemia-reperfusion-injury would improve the outcome of diabetic patients after a cardiovascular event. In the present study, we will use annexinA5 scintigraphy to address the following hypothesis:

Rosiglitazone reduces ischemia-reperfusion-injury in humans with insulin resistance.

Read the detailed description

Rationale: Cardiovascular disease is the leading cause of death in diabetic patients due to both a high event rate and a worse outcome. A pharmacological intervention that reduces ischemia-reperfusion-injury would improve the outcome of diabetic patients after a cardiovascular event. The thiazolidinedione derivatives are peroxisome proliferator-activated receptor-γ (PPARγ) ligands that are approved for the treatment of hyperglycemia in type 2 diabetes mellitus. Animal data suggest that PPARγ ligands can protect against ischemia-reperfusion-injury by improving insulin responsiveness. However, no human data on these beneficial effects are available. Recently, our group developed a human in vivo model to quantify ischemia-reperfusion-injury. In this model annexin A5 scintigraphy is used to visualize early and reversible cellular membrane changes that occur in the forearm skeletal muscle vascular bed after ischemic exercise. In the present study, we will use this approach to address the following hypothesis: Rosiglitazone reduces ischemia-reperfusion-injury in humans with insulin resistance, selected by using the criteria for the metabolic syndrome.

Study design: This is a single-center randomized, double blind, placebo-controlled crossover study with a washout period of 6 weeks.

Study population: Men and postmenopausal women, age 20-70 years with the metabolic syndrome.

Intervention: Every subject uses during 8 weeks rosiglitazone 4 mg bd and placebo bd. Week 8 and 22: assessment of ischemic-reperfusion injury with Technetium Annexin A5 Scintigraphy. Ischemic intervention: 10 minutes ischemia of the non-dominant arm with at the same time rhythmic contractions of the forearm and hand muscles.

Main study parameters/endpoints: Annexin targeting in the thenar muscle after ischemic exercise. The primary analysis is the difference in annexin targeting following 8 weeks of treatment with rosiglitazone 4 mg bd or placebo.

Secondary outcomes (2)
  1. The effect of rosiglitazone as compared to placebo on the HOMA-index.

  2. Changes in vital signs, body weight, clinical laboratory parameters and adverse events monitoring during the study.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing rosiglitazone in people with Ischemia-Reperfusion Injury and The Metabolic Syndrome, run by Radboud University Medical Center at 1 site in Netherlands.

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 3 inclusion and 10 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 24 Aug 2010. 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 Netherlands. 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.

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?

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?

Annexin targeting in the thenar muscle after ischemic exercise. The primary analysis is the difference in annexin targeting following 8 weeks of treatment with rosiglitazone 4 mg bd or placebo.. 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 NCT00405015, which also lists 4 linked publications.

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 24 Aug 2010.
