Recent and Ongoing Cardiovascular Outcomes Trials
with Diabetes Drugs
Upper bound of a 2-sided 95% confidence interval for estimated CV risk
>1.8 The data are inadequate to support approval. A large safety trial should be conducted
1.3 – 1.8 The potential for CV harm may still exist. An adequately powered and designed post-marketing trial is necessary to show an upper bound < 1.3*
<1.3 A post-marketing trial is generally not needed* *with a reassuring point estimate for overall CV risk

Medications
N Engl J Med 2013; 369:1317-1326

regime • Objective: To compare the impact of adding aleglitazar
or placebo to usual care, with regard to first occurrence of CVD death, non-fatal myocardial infarction, or non-fatal stroke
• Study Duration: up to 3.3 years, median 2.0 years
AleCardio - Primary End Point Standard MACE
JAMA. 2014;():. doi:10.1001/jama.2014.3321
Kaplan-Meier Estimates of Time to First Occurrence of Primary Efficacy End Point and Hospitalization for Heart FailureY-axis in blue indicates range from 0% to 10%. The primary efficacy end point was time to cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke.

AleCardio – Hospitalization for Heart Failure
JAMA. 2014;():. doi:10.1001/jama.2014.3321
Kaplan-Meier Estimates of Time to First Occurrence of Primary Efficacy End Point and Hospitalization for Heart FailureY-axis in blue indicates range from 0% to 10%. The primary efficacy end point was time to cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke.
Figure Legend:
• A serious adverse event of heart failure was reported in 4.7% of patients in the aleglitazar group and 3.8% of patients in the placebo group (HR, 1.24[95%CI,0.99-1.66],p = .06)
• More patients receiving aleglitazar developed peripheral edema (14.0%for aleglitazar vs 6.6% for placebo, p < .001)

New Diabetes
Conclusions • Early use of basal insulin glargine for > 6 years…
– had a neutral effect on CV events – was possible & feasible in a clinical trial setting – reduced progression from pre-diabetes to
diabetes by 28%, p = 0.006 – had a neutral effect on cancers – modestly increased weight & hypoglycemia
