ACCORD Study Design
• Designed to independently test three medical strategies to reduce cardiovascular disease in diabetic patients
• Lipid Trial question: whether combination therapy with a statin plus a fibrate would reduce cardiovascular disease compared to statin monotherapy in people with type 2 diabetes mellitus at high risk for cardiovascular disease.
• Randomized, placebo-controlled, double-blind clinical trial conducted in 77 clinical sites in the U.S. and Canada
ACCORD Study Design
• Overall ACCORD Glycemia Trial: 10,251 participants
• Lipid Trial: 5,518 participants • 2765 randomized to fenofibrate• 2753 randomized to placebo
• Primary Outcome: First occurrence of a major cardiovascular event (nonfatal MI, nonfatal stroke, cardiovascular death)
• 87% power to detect a 20% reduction in event rate, assuming placebo rate of 2.4%/yr and 5.6 yrs follow-up in participants without events.
ACCORD Lipid Trial Eligibility• Stable Type 2 Diabetes >3 months• HbA1c 7.5% to 11%• High risk of CVD events = clinical or subclinical disease or
2+ risk factors • Age
• ≥ 40 yrs with history of clinical CVD (secondary prevention)• ≥ 55 yrs otherwise
• Lipids• 60 < LDL-C < 180 mg/dl• HDL-C < 55 mg/dl for women/Blacks; < 50 mg/dl otherwise• Triglycerides < 750 mg/dl if on no therapy; < 400 mg/dl
otherwise
• No contraindication to either fenofibrate or simvastatin
ACCORD Lipid Protocol
All participants on open-labeled simvastatin, 20 to 40 mg/day◦ Simvastatin dose complied with lipid guidelines
Patients randomized to double-blind placebo or fenofibrate, 54 to 160mg/day◦ Dosing based upon eGFR level
Only blinded ACCORD trial

Conclusion (1)
• ACCORD Lipid does not support use of the
combination of fenofibrate and simvastatin,
compared to simvastatin alone, to reduce CVD
events in the majority of patients with T2DM who are
at high risk for CVD
Conclusion (2)
• Subgroup analyses suggesting heterogeneity in
response to combination therapy by gender or by
the presence of significant dyslipidemia require
further investigation
