The DREAM (Diabetes Reduction Assessment with Ramipril and Rosiglitazone Medication) Trial
To evaluate whether ramipril and/or rosiglitazone prevent the onset of type 2 diabetes in people with prediabetes and without cardiovascular disease. The trial found no clear benefit for ramipril and a large reduction in incident diabetes with rosiglitazone. Ramipril did not reduce the incidence of CV and renal events; Rosiglitazone reduced the incidence of renal events, had an overall neutral effect on CV events and increased the incidence of heart failure. Based on the trial results rosiglitazone is suggested as a possible therapy to reduce the risk for diabetes in some countries.
Randomized, double-blind, placebo control, factorial assignment, efficacy study.
The primary outcome was the composite newly diagnosed diabetes or death. The secondary endpoints include: the composite of CV events (myocardial infarction (MI), stroke, congestive heart failure, angina, revascularization procedures, and ventricular arrhythmia) and renal Events. All primary and secondary outcomes were adjudicated.
