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

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)

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
