Efficacy and Safety of Alirocumab as Add-on Therapy in High–Cardiovascular-Risk Patients With Hypercholesterolemia Not Adequately Controlled With Atorvastatin (20 or 40 mg) or Rosuvastatin (10 or 20 mg)::Design and Rationale of the ODYSSEY OPTIONS Studies

The phase 3 ODYSSEY OPTIONS studies (OPTIONS I, NCT01730040; OPTIONS II, NCT01730053) are multicenter, multinational, randomized, double-blind, active-comparator, 24-week studies evaluating the efficacy and safety of alirocumab, a fully human monoclonal antibody targeting proprotein convertase subtilisin/kexin type 9, as add-on therapy in ∼ 650 high-cardiovascular (CV)-risk patients whose low-density lipoprotein cholesterol (LDL-C) levels are ≥100 mg/dL or ≥70 mg/dL according to the CV-risk category, high and very high CV risk, respectively, with atorvastatin (20–40 mg/d) or rosuvastatin (10–20 mg/d). Patients are randomized to receive alirocumab 75 mg via a single, subcutaneous, 1-mL injection by prefilled pen every 2 weeks (Q2W) as add-on therapy to atorvastatin (20–40 mg) or rosuvastatin (10–20 mg); or to receive ezetimibe 10 mg/d as add-on therapy to statin; or to receive statin up-titration; or to switch from atorvastatin to rosuvastatin (OPTIONS I only). At week 12, based on week 8 LDL-C levels, the alirocumab dose may be increased from 75 mg to 150 mg Q2W if LDL-C levels remain ≥100 mg/dL or ≥70 mg/dL in patients with high or very high CV risk, respectively. The primary efficacy endpoint in both studies is difference in percent change in calculated LDL-C from baseline to week 24 in the alirocumab vs control arms. The studies may provide guidance to inform clinical decision-making when patients with CV risk require additional lipid-lowering therapy to further reduce LDL-C levels. The flexibility of the alirocumab dosing regimen allows for individualized therapy based on the degree of LDL-C reduction required to achieve the desired LDL-C level

Are post-treatment low-density lipoprotein subclass pattern analyses potentially misleading?

<p>Abstract</p> <p>Background</p> <p>Some patients administered cholesterol-lowering therapies may experience an increase in the proportion of small LDL particles, which may be misinterpreted as a worsening of atherosclerotic coronary heart disease risk. This study assessed the lipid effects of adding ezetimibe to atorvastatin or doubling the atorvastatin dose on low-density lipoprotein cholesterol (LDL-C) levels (and the cholesterol content of LDL subclasses), LDL particle number (approximated by apolipoprotein B), and LDL particle size. This was a multicenter, double-blind, randomized, parallel-group study of hypercholesterolemic, high atherosclerotic coronary heart disease risk patients. After stabilization of atorvastatin 40 mg, 579 patients with LDL-C >70 mg/dL were randomized to 6 weeks of ezetimibe + atorvastatin 40 mg or atorvastatin 80 mg. Efficacy parameters included changes from baseline in LDL-C, apolipoprotein B, non-high-density lipoprotein cholesterol (non-HDL-C), and lipoprotein subclasses (Vertical Auto Profile II) and pattern for the overall population, as well as patient subgroups with baseline triglyceride levels <150 mg/dL or ≥150 mg/dL.</p> <p>Results</p> <p>Both treatments significantly reduced LDL-C (and the cholesterol content of most LDL subfractions [LDL_1-4]) apolipoprotein B, non-HDL-C levels, but did not reduce the proportion of smaller, more dense LDL particles; in fact, the proportion of Pattern B was numerically increased. Results were generally similar in patients with triglyceride levels <150 or ≥150 mg/dL.</p> <p>Conclusions</p> <p>When assessing the effects of escalating cholesterol-lowering therapy, effects upon Pattern B alone to assess coronary heart disease risk may be misleading when interpreted without considerations of other lipid effects, such as reductions in LDL-C, atherogenic lipoprotein particle concentration, and non-HDL-C levels.</p> <p>Trial Registration</p> <p>(Registered at clinicaltrials.gov: Clinical trial # NCT00276484)</p

Safety and Efficacy of Long-Term Co-Administration of Fenofibrate and Ezetimibe in Patients With Mixed Hyperlipidemia

ObjectivesThis study sought to determine the long-term safety and efficacy of co-administered fenofibrate (FENO) and ezetimibe (EZE) in patients with mixed hyperlipidemia.BackgroundBoth EZE and FENO offer complementary benefits to the lipid profile of patients with mixed hyperlipidemia.MethodsAfter completing the 12-week randomized, double-blind base study that compared EZE 10 mg, FENO 160 mg, FENO 160 mg plus EZE 10 mg, and placebo in patients with mixed hyperlipidemia, patients continued into a double-blind, 48-week extension phase. Those patients in the FENO plus EZE and FENO groups continued on their respective base study treatment, and patients in the EZE and placebo groups were switched to FENO plus EZE and FENO, respectively.ResultsOf the 587 patients who completed the base study, 576 continued into the extension study (n = 340 in FENO plus EZE and n = 236 in FENO). The FENO plus EZE produced significantly greater reductions in low-density lipoprotein-cholesterol compared with FENO (−22% vs. −9%, respectively; p < 0.001). There were also significantly greater improvements in triglycerides, high-density lipoprotein cholesterol (HDL-C), total cholesterol, non–HDL-C, and apolipoprotein B with FENO plus EZE compared with FENO. Changes in apolipoprotein A-I and high-sensitivity C-reactive protein were similar between groups. Overall, FENO plus EZE was well tolerated during the extension study. The proportion of patients with consecutive elevations of alanine aminotransferase/aspartate aminotransferase ≥3 times upper limit of normal were similar between the FENO plus EZE (1.2%) and FENO (1.7%) groups. No cases of creatine phosphokinase elevations ≥10 times upper limit of normal or myopathy were observed in either group.ConclusionsLong-term, 48-week co-administration of FENO plus EZE was well tolerated and more efficacious than FENO in patients with mixed hyperlipidemia

Bempedoic acid safety analysis: Pooled data from four phase 3 clinical trials

Background An ongoing need exists for safe and effective lipid-lowering therapies (LLTs) for patients unable to achieve desired lipid levels with current treatment options. Objective The objective of this study was to describe the safety profile of bempedoic acid, an oral, first-in-class, adenosine triphosphate (ATP)–citrate lyase inhibitor that significantly reduces low-density lipoprotein cholesterol (LDL-C) levels by 17.4%–28.5% vs placebo. Methods This was a pooled analysis of four phase 3, randomized (2:1), double-blind, placebo-controlled studies in patients with hypercholesterolemia who required additional LDL-C lowering, despite stable maximally-tolerated LLT. Patients received 180 mg of bempedoic acid (n = 2424) or placebo (n = 1197) once daily for 12 to 52 weeks. Assessments included treatment-emergent adverse events (TEAEs) and clinical laboratory tests. Results Of 3621 patients (the median drug exposure: 363 days), exposure-adjusted TEAE rates were 87.1/100 and 82.9/100 person-years (PY) for bempedoic acid and placebo, respectively. No single TEAE influenced the difference in rates. TEAEs leading to discontinuation occurred at rates of 13.4/100 and 8.9/100 PY for bempedoic acid vs placebo, with the most common cause being myalgia, which occurred less frequently with bempedoic acid vs placebo (1.5/100 vs 2.0/100 PY). Rates of myalgia and muscle weakness were comparable vs placebo. Bempedoic acid was associated with mild increases in blood urea nitrogen, creatinine, and uric acid and decreases in hemoglobin. These laboratory abnormalities were apparent by week 4, stable over time, and reversible after treatment cessation. Gout incidence was 1.6/100 vs 0.5/100 PY in the bempedoic acid vs placebo groups. New-onset diabetes/hyperglycemia occurred less frequently with bempedoic acid vs placebo (4.7/100 vs 6.4/100 PY). The safety profile was consistent across subgroups. Conclusions Bempedoic acid is generally safe and well tolerated among patients with hypercholesterolemia who require additional LLT

Icosapent ethyl, a pure EPA omega-3 fatty acid: Effects on lipoprotein particle concentration and size in patients with very high triglyceride levels (the MARINE

BACKGROUND: Icosapent ethyl (IPE; formerly AMR101) is a high-purity prescription form of eicosapentaenoic acid ethyl ester. In the MARINE study we evaluated the efficacy and safety of IPE in patients with very high triglycerides (TG; $500 mg/dL) and previously demonstrated significant reductions in TG levels with no significant increases in low-density lipoprotein (LDL) cholesterol levels. OBJECTIVES: In this follow-up, exploratory analysis, we report the effects of IPE on lipoprotein particle concentration and size. METHODS: MARINE was a phase 3, multicenter, placebo-controlled, randomized, double-blind, 12-week study. Hypertriglyceridemic patients (N 5 229) were randomized to three treatment groups: IPE 4 g/day, IPE 2 g/day, or placebo. Lipoprotein particle concentrations and sizes were measured by nuclear magnetic resonance spectroscopy. RESULTS: Compared with placebo, IPE 4 g/day significantly reduced median concentrations of large very-low-density lipoprotein (VLDL; 227.9$500 mg/dL, IPE did not significantly change the overall sizes of LDL or HDL particles. CONCLUSION: IPE 4 g/day significantly reduced large VLDL, total LDL, small LDL, and total HDL particle concentrations and VLDL particle size in patients with TG $500 mg/dL. Changes in VLDL particle concentration and size reflect the TG-lowering effects of eicosapentaenoic acid. The reduction in LDL particle concentration with IPE is novel among u-3 therapies and is consistent with the previously reported reduction in apolipoprotein B and lack of LDL-C increase with IPE in patients with very high TG levels.
