Abstract

Background

Aggressive treatment of low-density lipoprotein cholesterol (LDL-C) fails to prevent most cardiovascular (CV) events. Concurrent treatment of LDL-C, high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) should be considered in patients with dyslipidemia.

Objective

The efficacy and safety of a proprietary niacin extended-release and simvastatin (NER/S) combination were compared to atorvastatin monotherapy in a multicenter, Prospective, Randomized (3:2), Open-label, Blinded Endpoint (PROBE) study.

Methods

Following ≥4 weeks without lipid-modifying therapies, 193 patients with dyslipidemia were treated with NER/S (n = 114; 1000/40 mg/day, weeks 1 to 4; 2000/40 mg/day weeks 5 to 12) or atorvastatin (n = 79; 40 mg/day, weeks 1 to 12).

Results

Compared to atorvastatin, NER/S had a larger beneficial effect on HDL-C (primary end point: 30.1 ± 2.3% and 9.4 ± 2.6%, respectively; P <.001), TG (P = .02), and lipoprotein(a) (Lp[a]; P <.001), and similar effects on LDL-C and non-HDL-C. Two-thirds of patients treated with NER/S concurrently attained LDL-C (CV risk-adjusted goals), HDL-C (≥40 mg/dL), and TG (<150 mg/dL) targets, compared to one-third of patients treated with atorvastatin (P <.001). Flushing was the most common treatment-emergent adverse event (TEAE) (67.5% NER/S and 10.1% atorvastatin; P <.001). Seventy-five percent of flushing episodes were mild to moderate. More patients treated with NER/S discontinued due to TEAEs (21.1% and 3.8%; P <.001); the most common TEAE was flushing.

Conclusion

Compared to atorvastatin, NER/S provided superior improvements in HDL-C, TG, and Lp(a) and comparable improvements in non-HDL-C and LDL-C. Treatment with NER/S should be considered for patients with dyslipidemia requiring comprehensive lipid control.
