Arm | Intervention/treatment |
---|---|
Experimental: Glycemia Trial: intensive control
Open label administration of oral anti-hyperglycemic agents and/or insulin in combination with dietary/lifestyle advice as needed to achieve glycated hemoglobin (HbA1c) levels <6.0%.
|
Drug: Anti-hyperglycemic Agents
Multiple drugs including insulins and oral anti-hyperglycemic agents as needed to reach Glycemia Trial arm-specific goals (intensive control <6%; standard control 7.0-7.9%).
Other Names:
|
Active Comparator: Glycemia Trial: standard control
Open label administration of oral anti-hyperglycemic agents and/or insulin in combination with dietary/lifestyle advice as needed to achieve glycated hemoglobin (HbA1c) levels of 7.0 - 7.9%.
|
Drug: Anti-hyperglycemic Agents
Multiple drugs including insulins and oral anti-hyperglycemic agents as needed to reach Glycemia Trial arm-specific goals (intensive control <6%; standard control 7.0-7.9%).
Other Names:
|
Experimental: BP Trial: intensive control
Open label administration of anti-hypertensive agents to reduce and maintain systolic blood pressure (SBP) level to <120 mmHg.
|
Drug: Anti-hypertensive Agents
Multiple anti-hypertensive agents as needed to reach Blood Pressure Trial arm-specific goals (intensive control <120 mm Hg; standard control <140 mm Hg).
Other Names:
|
Active Comparator: BP Trial: standard control
Open label administration of multiple anti-hypertensive agents to maintain SBP level <140 mm Hg.
|
Drug: Anti-hypertensive Agents
Multiple anti-hypertensive agents as needed to reach Blood Pressure Trial arm-specific goals (intensive control <120 mm Hg; standard control <140 mm Hg).
Other Names:
|
Experimental: Lipid Trial: fenofibrate
Double blind administration of 160 mg/day of fenofibrate in participants with estimated glomerular filtration rate (eGFR) ≥50 mL/min/1.73m2 or 54 mg/day in patients with eGFR <50 mL/min/1.73m2 in combination with open label simvastatin.
|
Drug: Blinded fenofibrate or placebo plus simvastatin
Double blind administration of 160 mg/day of fenofibrate in participants with estimated glomerular filtration rate (eGFR) ≥50 mL/min/1.73m2 or 54 mg/day in patients with eGFR <50 mL/min/1.73m2 or matching placebo in combination with open label simvastatin 20 - 40 mg/day.
Other Name: fenofibrate (Tricor) |
Placebo Comparator: Lipid Trial: placebo
Double blind administration of placebo matching either 160 mg/day in participants with eGFR ≥50 mL/min/1.73m2 or 54 mg/day in participants with eGFR <50 mL/min/1.73m2 in combination with open label simvastatin.

Drug: Blinded fenofibrate or placebo plus simvastatin

- First Occurrence of a Major Cardiovascular Event (MCE); Specifically Nonfatal Heart Attack, Nonfatal Stroke, or Cardiovascular Death (Measured Throughout the Study) in the Glycemia Trial. [ Time Frame: 4.9 years ]
Time to first occurrence of nonfatal myocardial infarction, nonfatal stroke, or cardiovascular death. This was the primary outcome measure in all three trials: Glycemia (all participants), Blood Pressure (subgroup of participants not in Lipid Trial), and Lipid (subgroup of participants not in Blood Pressure Trial).
In the Glycemia Trial, a finding of higher mortality in the intensive arm group led to an early discontinuation of therapy after a mean of 3.5 years of follow-up. Intensive arm participants were transitioned to standard arm strategy over a period of 0.2 year and followed for an additional 1.2 years to the planned end of the Glycemia Trial while participating in one of the other sub-trials (BP or Lipid) to their planned completion.
- First Occurrence of Major Cardiovascular Event (MCE) in the Blood Pressure Trial. [ Time Frame: 4.7 years ]Time to first occurrence of nonfatal myocardial infarction, nonfatal stroke, or cardiovascular death. Primary outcome for Blood Pressure Trial.
- First Occurrence of Major Cardiovascular Event (MCE) in the Lipid Trial. [ Time Frame: 4.7 years ]Time to first occurrence of nonfatal myocardial infarction, nonfatal stroke, or cardiovascular death in Lipid Trial participants.
- Death From Any Cause in the Glycemia Trial. [ Time Frame: 4.9 years ]
Time to death from any cause. Secondary measure for Glycemia Trial.
A finding of higher mortality in the intensive-therapy group led to an early discontinuation of therapy after a mean of 3.5 years of follow-up. Intensive arm participants were transitioned to standard arm strategy over a period of 0.2 year and followed for an additional 1.2 years to the planned end of the Glycemia Trial while participating in one of the other sub-trials (BP or Lipid).
- Stroke in the Blood Pressure Trial. [ Time Frame: 4.7 years ]Time to first occurrence of nonfatal or fatal stroke among participants in the BP Trial.
- First Occurrence of MCE or Revascularization or Hospitalization for Congestive Heart Failure (CHF) in Lipid Trial. [ Time Frame: 4.7 years ]Time to first occurrence of nonfatal myocardial infarction, nonfatal stroke, cardiovascular death, revascularization procedure or hospitalization for CHF in Lipid Trial participants.
