Time in days to death, non-fatal myocardial infarction, stroke, hospitalization for unstable angina, or symptom-driven coronary revascularization [ Time Frame: through study completion, an average of 4.5 years ] The primary outcome measure is the time to first occurrence of death, non-fatal myocardial infarction or stroke, hospitalization for unstable angina with objective evidence of acute myocardial ischemia, or coronary revascularization driven by acute or progressive symptoms.

Official Title ICMJE | CSP #2002 - Investigation of Metformin in Pre-Diabetes on Atherosclerotic Cardiovascular OuTcomes (VA-IMPACT) | ||||||
Brief Summary | This research will help us to learn if the medicine called metformin reduces the risk of death, heart attacks, and/or strokes in patients who have pre-diabetes and heart or blood vessel problems. | ||||||
Detailed Description | CSP #2002 is a multicenter, prospective, randomized, double blind, secondary prevention trial to test the hypothesis that treatment with metformin, compared with placebo, reduces mortality and cardiovascular morbidity in patients with pre-diabetes and established atherosclerotic cardiovascular disease. Qualifying patients have pre-diabetes defined by HbA1c, fasting blood glucose, or oral glucose tolerance test criteria; clinically evident coronary, cerebrovascular, or peripheral arterial atherosclerotic cardiovascular disease; and estimated glomerular filtration rate of at least 45 mL/min/1.73 m2; and do not fulfill any exclusion criteria. Patients who are eligible and agree to participate are randomly assigned to treatment with metformin XR (titrated to a maximum dose of 2000 mg daily based on safety and tolerability) or matching placebo. All patients receive counseling on therapeutic lifestyle recommendations. CSP #2002 had a Pilot Phase trial from 2/2019 to 1/2021 and was approved for the full-scale trial, with projected full-scale launch in 10/2022. |
