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.
