7 20/09/2018 Niacin monotherapy outcomes trial: 15-year follow-up in Coronary Drug Project 11% Reduction p=0.0004 Placebo (n = 2008) Niacin (n = 827) 12% Reduction p<0.05 Event Rate, % The Coronary Drug Project (CDP) is so far the only published outcomes study with niacin (nicotinic acid, immediate-release formulation) monotherapy. At 15 years (nearly 9 years after termination of the trial) total mortality in the niacin group was 11% lower than in the placebo group (p=0.0004). CHD mortality was also significantly decreased in the niacin group (12% reduction, p<0.05). However, mortality at 15 years was not an original end point of the CDP, patients had not received niacin for approximately 9 years, and confounding variables such as concomitant medication use and medical or surgical treatments, were not controlled in this follow-up study. Results from this follow-up study indicated that early treatment with niacin may provide a mortality benefit over subsequent years, even after discontinuation of niacin. Reference Canner PL et al.

The COMPELL study evaluated comparative effects on lipid levels of combination therapy with ER niacin and low to moderate doses of a statin (atorvastatin or rosuvastatin), simvastatin plus ezetimibe, and rosuvastatin monotherapy. This was an open-label, multicentre, 12-week study in 292 patients (50% women) who qualified for lipid-modifying therapy based on a number of coronary risk factors. Doses of statins and niacin were titrated up over the 12 weeks. At 12 weeks, all groups lowered LDL cholesterol by more than 50%, with no significant differences among treatment groups. Statin/ER niacin combination regimens increased HDL cholesterol and lowered triglycerides and lipoprotein(a) significantly more than the other regimens (p<.001 for analysis of variance across groups). In summary, low to moderate dose combination therapy with a statin and ER niacin provided broad control of lipids and lipoproteins independently associated with coronary heart disease.

9 SEACOAST: Trial design
20/09/2018 After a run-in phase (treatment with simvastatin, variable dose), patients were randomly assigned to either: SEACOAST I: ER niacin 1 g/simvastatin 20 mg; ER niacin 2 g/simvastatin 20 mg; or Simvastatin 20 mg. OR SEACOAST II: ER niacin 2 g/simvastatin 40 mg; ER niacin 1 g/simvastatin 40 mg; or Simvastatin 80 mg. The duration of treatment was 24 weeks. The SEACOAST trial evaluated the effects of combination therapy with a statin and two doses of ER niacin in dyslipidemic patients. Patients were initially enrolled in a run-in phase during which they discontinued all other lipid-modifying therapy and were treated with simvastatin (variable dose), in addition to a standard cholesterol-lowering diet. Following this phase more than 600 patients were randomly assigned to either the low-dose (20 mg) or high-dose (40 mg) simvastatin arm. Patients in the low-dose group (SEACOAST I) were randomized to: ER niacin 1 g/simvastatin 20 mg; ER niacin 2 g/simvastatin 20 mg; or Simvastatin 20 mg. Patients in the high-dose group (SEACOAST II) were randomized to: ER niacin 2 g/simvastatin 40 mg; ER niacin 1 g/simvastatin 40 mg; or Simvastatin 80 mg. Patients in the simvastatin monotherapy groups received a 50 mg dose of immediate-release niacin to maintain study blinding. Reference Ballantyne CM et al.

Patients receiving niacin-statin combination treatment achieved 18% (1 g/20 mg) and 25% (2 g/20 mg) increases in HDL cholesterol vs 7% reduction with simvastatin 20 mg alone. Combination treatment also significantly reduced LDL cholesterol, non-HDL cholesterol, lipoprotein(a) and triglycerides compared with simvastatin monotherapy. Reference Ballantyne CM et al.

12 20/09/2018 Frequency of flushing >2x as many patients on ER-niacin/laropiprant than ER-niacin had no flushing (47% vs. 22%) Flushing is the main tolerability issue with niacin therapy. The combination of niacin with laropiprant, an inhibitor of the prostaglandin D2 receptor, was developed in attempt to manage this. In this study, patients treated with ER-niacin/laropiprant had significantly less flushing than those treated with ER-niacin over the 16-week period. Overall, more than twice as many patients reported no episodes of moderate, severe or extreme flushing with ER-niacin/laropiprant than ER-niacin (47% vs. 22%). Additionally, treatment with ER-niacin/laropiprant was associated with significantly less severe/extreme flushing (24.4% vs. 50.8%, p<0.001). Reference Maccubbin D et al. Am J Cardiol 2009;104:74-81.

20/09/2018 HDL Atherosclerosis Treatment Study (HATS): Mean change in stenosis Mean change in stenosis (% of diameter) Regression Progression Statin/niacin + antioxidants 0.7%* Statin/niacin 0.4%** Antioxidants 1.8%* HATS: HDL Atherosclerosis Treatment Study HATS evaluated the effect of combination treatment with simvastatin plus niacin in 160 patients with coronary heart disease and low HDL cholesterol levels and normal LDL cholesterol levels. Combination therapy resulted in a 29% increase in plasma levels of HDL cholesterol (versus 6% with placebo) together with reductions of 38% (versus 3%) in triglycerides and 43% (versus 9%) in LDL cholesterol. After 3 years, there was significant angiographic regression of stenosis by 0.4% on average, compared with placebo (p<0.001); the addition of anti-oxidants had no influence on this effect. However, HATS did not include a separate simvastatin treatment arm and therefore the incremental benefit of nicotinic acid over statin alone could not be discerned. Reference Brown BG et al.

20/09/2018 ARBITER 2: Change in carotid intima-media thickness at 12 months Niacin plus statin stabilized progression of atherosclerosis BUT Significant progression of atherosclerosis with statin alone Taylor et al . Circulation 2004; 110: ARBITER-2: ARterial Biology for the Investigation of the Treatment Effects of Reducing cholesterol study ARBITER 2 included 167 patients with known coronary heart disease, moderately low HDL cholesterol (< 45 mg/dl [1.2 mmol/l]) and well-controlled LDL cholesterol (< 100 mg/dl [2.6 mmol/l]), who had been treated with a statin (93% with simvastatin) for an average of 4.8 years. Patients were randomised to treatment with ER niacin (500 mg for the first 30 days and 1000 mg daily thereafter) or placebo in addition to statin therapy for 12 months. The primary endpoint of the study was the change in carotid intima-media thickness (CIMT) at 12 months, as measured by B-mode ultrasonography, which is a meaningful and validated surrogate cardiovascular endpoint. Combination therapy raised HDL cholesterol by 21% (p=0.002) and reduced triglycerides, versus statin monotherapy. At 12 months, there was no significant change in CIMT in the statin/ER niacin combination group (  mm, p=0.23) whereas in patients treated with statin alone there was a significant increase in CIMT (  mm, p<0.001), indicative of increased progression of atherosclerosis.

Raising HDL-C with extended-release (ER) niacin (target dose 2 g/day) 2. Further lowering LDL-C levels with ezetimibe (10 mg/day) The primary endpoint was the change in carotid intima-media thickness (IMT), a measure of atherosclerosis. The study was terminated 4 months early on the recommendation of an independent data advisory board on the basis of efficacy, according to a pre-specified interim analysis of carotid IMT 8 and 14-month data. At this time 208 (of 363 enrolled) patients had completed the study. Treatment with niacin led to significant reduction in mean carotid IMT at both 8 and 14 months (p=0.001 at each time point). In contrast, no significant changes were observed in patients treated with ezetimibe. The change from baseline to 14 months in the primary endpoint was significantly different between the niacin and ezetimibe groups (p=0.003). Reference Taylor AJ et al.

Fenofibrate alone significantly raised HDL cholesterol by 16%, and also reduced triglycerides by 41% and LDL cholesterol by 15%. Changes in HDL cholesterol and triglycerides were greater in combination with atorvastatin. Reference Athyros VG et al.

In total, 418 patients with type 2 diabetes mellitus and at least one angiographically confirmed coronary lesion were included. Treatment with fenofibrate produced a significant increase in HDL cholesterol (p<0.001), together with significant reductions in LDL cholesterol and triglycerides (p<0.001) versus placebo. These lipid changes were associated with significantly less progression in markers of focal coronary artery disease, specifically minimum lumen diameter (p=0.029) and percent stenosis (p=0.02), as well as a non-significant trend for less progression in mean segment diameter, a marker of diffuse disease, compared with placebo.

Treatment with gemfibrozil was associated with a 6% increase in HDL cholesterol levels and 31% decrease in fasting triglyceride levels compared with placebo at one year, with no appreciable change in LDL cholesterol levels. At the median follow-up of 5.1 years, raising HDL cholesterol (together with reduction of triglycerides) was associated with a 22% reduction in the primary endpoint (nonfatal MI and CHD death, p=0.006), as well as 22% reduction in CHD death (p=0.07) and 29% reduction in stroke (p=0.04).

20 ACCORD Lipid: Combination fenofibrate/simvastatin in Type 2 diabetes
20/09/2018 Hazard ratio for primary outcome P-value for interaction P=0.01 All patients HDL-C ≤34 mg/dL TG ≥204 mg/dL P=0.06 The Action to Control Cardiovascular Risk in Diabetes (ACCORD) Lipid population comprised a cohort of 5,518 high-risk type 2 diabetic patients at goal for LDL cholesterol. The key question addressed by the trial was whether in the context of good glycemic control, fenofibrate plus simvastatin was more effective in reducing cardiovascular events than simvastatin monotherapy. ACCORD Lipid randomized 5,518 high-risk type 2 diabetes patients at target for LDL cholesterol (100 mg/dL or 2.6 mmol/L at baseline decreasing to 80 mg/dL or ~2.0 mmol/L on simvastatin, mean dose 22 mg/day) to fenofibrate plus simvastatin or simvastatin alone. ACCORD Lipid did not show any significant clinical benefit for any of the primary or secondary cardiovascular outcomes in the total study population. However, in a pre-defined subgroup analysis in patients with HDL cholestesterol levels <34 mg/dL and triglycerides ≥204 mg/dL at baseline (17% of the total population), there was suggestion of benefit. Adding fenofibrate resulted in 31% reduction versus simvastatin treatment alone, although this was not statistically significant. Reference The ACCORD Study Group.
