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 in Lipid Trial
• 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 (limited to <80 years after Vanguard)
•
•
≥ 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

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

Observed Follow-up: 4 to 8 years (mean 4.7 years)

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 have HDLC and TG levels that are close to the normal range
Conclusion (2)
• Subgroup analyses suggesting heterogeneity in
response to combination therapy by gender and by
the presence of significant dyslipidemia require
further investigation
