Differences between conventional glycemic trial and CVOTs 11.

Conventional glycemic efficacy trials CVOTs
Objective Efficacy of drug compared with a placebo or comparator Compare CV outcomes
Number of patients 300–600 (based on sample size calculation) In thousands
Duration 26–104 weeks Many years or event driven
Background glycemic therapies Limited to rescue therapies and dose changes for hypoglycemia More flexibility for investigator
Comparator Placebo or active comparator Usually placebo
Inclusion/exclusion Mainly low-risk patients or minimal CV risk Patients with high CV risk factors, known atherosclerotic vascular disease, recent CV event

CVOT: cardiovascular outcome trial; CV:cardiovascular.
