Section snippets
Study Design
AIM-HIGH was a randomized, placebo-controlled clinical trial designed to test the hypothesis that in patients with atherosclerotic cardiovascular disease and atherogenic dyslipidemia, treatment with ERN (Niaspan, AbbVie, Inc, North Chicago, IL) to raise baseline levels of high-density lipoprotein cholesterol (HDL-C) would decrease the rate of cardiovascular endpoints (coronary artery disease death, nonfatal myocardial infarction, ischemic stroke, hospitalization for acute coronary syndrome or
Baseline Status
Of the 3414 randomized participants, all but 2 could be classified by glycemic status at baseline. Approximately 34% (n = 1158) had previously diagnosed diabetes; a further 164 (4.8%) were found to have diabetes by baseline FG testing, making a total of 1322 subjects (38.7%) with baseline diabetes. Almost 30% (n = 1010) had IFG and 32% (n = 1080) had NFG. Those with diabetes at baseline were older and had higher HbA1c but lower LDL-C levels than those without diabetes, and participants with
Discussion
The principal findings of this analysis of the AIM-HIGH population comparing the effects of ERN vs Placebo added to simvastatin/ezetimibe over a mean 3-year follow-up period on glucose and insulin levels, were that FG levels increased modestly but significantly more in the ERN than the Placebo group, irrespective of whether participants had NFG, IFG, or diabetes at baseline. This difference was accompanied by a significant worsening of insulin resistance as assessed by insulin and HOMA-IR

Effect of bempedoic acid on new onset or worsening diabetes: A meta-analysis
2020, Diabetes Research and Clinical PracticeCitation Excerpt :In some cases, the effect on glycemic metabolism was negative. The addition of extended-release niacin to statins had deleterious effects on glycemia in those with diabetes at baseline, and there was a trend toward increased development of new-onset diabetes [5]. In other cases, the effect was neutral.

2017, Journal of Clinical LipidologyCitation Excerpt :However, our analysis showed that in AIM-HIGH participants without MS at baseline, ERN did not affect the rate of subsequent MS. This could be explained by the previously mentioned unfavorable effect of niacin on insulin resistance and the potential concern that developing DM on ERN might have offset the positive effect on lipids. Recent AIM-HIGH data demonstrate that ERN increased development of DM and impaired fasting glucose.18 This was a post hoc analysis of a clinical trial, which has the potential for inherent selection bias as well reduced power to demonstrate difference.
Drugs That Affect Lipid Metabolism
2017, Side Effects of Drugs AnnualCitation Excerpt :Though limited by its size, design as a dose-finding trial, and lack of randomization or comparison to placebo, this study provides an early look at the safety, tolerability, and potential therapeutic use of niacin in pediatric patients. A recent prespecified secondary intention to treat (ITT) analysis of the 2011 AIM-HIGH trial sought to elucidate the effect of extended release niacin (Niaspan) on fasting glucose (FG) and insulin levels in statin-treated nondiabetic patients with a history of cardiovascular disease [7MC]. Patients included in this trial were 45 years or older had established cardiovascular disease, low HDL-C, triglycerides 100–400 mg/dL, and LDL-C < 180 mg/dL.
Cardiovascular outcomes during extended follow-up of the AIM-HIGH trial cohort
2018, Journal of Clinical LipidologyCitation Excerpt :Analysis of subpopulations also provided further support of the neutral findings as well as some concerns for ERN use. When diabetes was present at baseline, ERN appeared to be associated with only marginal effects on glycemia.23 However, there was a significant increase in fasting blood glucose levels at 1 year in those participants with normal or impaired fasting glucose levels at baseline, as well as a 17% absolute increase in diabetes in those with normal baseline glucose values.

Funding: The Atherothrombosis Intervention in Metabolic syndrome with low high-density lipoprotein/high triglycerides: Impact on Global Health (AIM-HIGH) study was supported by the National Heart, Lung, and Blood Institute (U01 HL081616 and U01 HL081649) and by an unrestricted grant from AbbVie, Inc. AbbVie donated the extended-release niacin, the matching placebo, and the ezetimibe; Merck donated the simvastatin. Neither of these companies had any role in the oversight or design of the study or in the analysis or interpretation of the data.
