Lipid lowering with bempedoic acid added to a proprotein convertase subtilisin/kexin type 9 inhibitor therapy: A randomized, controlled trial.

Background: Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9is) lower low-density lipoprotein cholesterol (LDL-C) in patients with hypercholesterolemia. However, some patients receiving PCSK9i therapy might require additional lipid-lowering therapy (LLT) to reach LDL-C goals. Bempedoic acid is an oral, once-daily, ATP-citrate lyase inhibitor that significantly lowers LDL-C in patients with hypercholesterolemia when given alone or as add-on therapy to statins and/or ezetimibe.

Alirocumab in high-risk patients: Observations from the open-label expanded use program.

Background: The alirocumab expanded use program provided open-label access to alirocumab before its commercial availability to patients with severe hypercholesterolemia not controlled with maximally tolerated doses of standard-of-care lipid-lowering therapy.

Objective: To describe the safety and lipid-lowering efficacy of alirocumab in high-risk patients who were likely to be early users of proprotein convertase subtilisin/kexin type 9 inhibitors after approval.

Methods: Patients with heterozygous familial hypercholesterolemia (HeFH) and/or coronary heart disease (CHD) and baseline low-density lipoprotein cholesterol (LDL-C) of ≥160 mg/dL on maximally tolerated lipid-lowering therapy were enrolled and received alirocumab 150 mg every 2 weeks for 24 weeks.

Efficacy and Safety of Alirocumab Versus Ezetimibe Over 2 Years (from ODYSSEY COMBO II).

The proprotein convertase subtilisin/kexin type 9 inhibitor alirocumab has been shown to substantially reduce low-density lipoprotein cholesterol (LDL-C). Demonstrating whether efficacy and safety are maintained over a long duration of exposure is vital for clinical decision-making. The COMBO II trial compared the efficacy and safety of alirocumab versus ezetimibe over 2 years.

Treatment with ETC-1002 alone and in combination with ezetimibe lowers LDL cholesterol in hypercholesterolemic patients with or without statin intolerance.

Background: ETC-1002 is an oral, once-daily, first-in-class medication being developed to treat hypercholesterolemia.

Objectives: To compare 2 doses of ETC-1002, alone or combined with ezetimibe 10 mg (EZE), vs EZE monotherapy for lowering low-density lipoprotein cholesterol (LDL-C).

Methods: This phase 2b, multicenter, double-blind trial-evaluated hypercholesterolemic patients (LDL-C, 130 to 220 mg/dL) with (n = 177) or without (n = 171) muscle-related intolerance to ≥2 statins; 1 at lowest approved dose.

Effect of ETC-1002 on Serum Low-Density Lipoprotein Cholesterol in Hypercholesterolemic Patients Receiving Statin Therapy.

ETC-1002 is an oral, once-daily medication that inhibits adenosine triphosphate citrate lyase, an enzyme upstream of 3-hydroxy-3-methylglutaryl-coenzyme A reductase, to reduce cholesterol biosynthesis. ETC-1002 monotherapy has demonstrated significant reduction in low-density lipoprotein cholesterol (LDL-C) compared with placebo in phase 2 studies. The objective of this study was to compare the lipid-lowering efficacy of ETC-1002 versus placebo when added to ongoing statin therapy in patients with hypercholesterolemia.

JCL roundtable: PCSK9 inhibitors in clinical practice.

The roundtable this month will involve a discussion of two new drugs that have been approved by the Food and Drug Administration for the reduction of low-density lipoprotein cholesterol (LDL-C). The Food and Drug Administration approved the first of these, alirocumab as an "adjunct to diet and maximally tolerated statin therapy for the treatment of adults with heterozygous familial hypercholesterolemia or clinical atherosclerotic cardiovascular disease, who require additional lowering of LDL [low-density lipoprotein]-cholesterol." Evolucumab has similar indications plus an indication specifically for treatment of homozygous familial hypercholesterolemia.

National Lipid Association Recommendations for Patient-Centered Management of Dyslipidemia: Part 2.

An Expert Panel convened by the National Lipid Association previously developed a consensus set of recommendations for the patient-centered management of dyslipidemia in clinical medicine (part 1). These were guided by the principle that reducing elevated levels of atherogenic cholesterol (non-high-density lipoprotein cholesterol and low-density lipoprotein cholesterol) reduces the risk for atherosclerotic cardiovascular disease. This document represents a continuation of the National Lipid Association recommendations developed by a diverse panel of experts who examined the evidence base and provided recommendations regarding the following topics: (1) lifestyle therapies; (2) groups with special considerations, including children and adolescents, women, older patients, certain ethnic and racial groups, patients infected with human immunodeficiency virus, patients with rheumatoid arthritis, and patients with residual risk despite statin and lifestyle therapies; and (3) strategies to improve patient outcomes by increasing adherence and using team-based collaborative care.

Effect of PCSK9 Inhibition by Alirocumab on Lipoprotein Particle Concentrations Determined by Nuclear Magnetic Resonance Spectroscopy.

Background: In patients with discordance between low-density lipoprotein (LDL) cholesterol and LDL particle (LDL-P) concentrations, cardiovascular risk more closely correlates with LDL-P.

Methods And Results: We investigated the effect of alirocumab, a fully human monoclonal antibody to proprotein convertase subtilisin/kexin type 9, on lipoprotein particle concentration and size in hypercholesterolemic patients, using nuclear magnetic resonance spectroscopy. Plasma samples were collected from patients receiving alirocumab 150 mg every 2 weeks (n=26) or placebo (n=31) during a phase II, double-blind, placebo-controlled trial in patients (LDL cholesterol ≥100 mg/dL) on a stable atorvastatin dose.

National lipid association recommendations for patient-centered management of dyslipidemia: part 1--full report.

The leadership of the National Lipid Association convened an Expert Panel to develop a consensus set of recommendations for patient-centered management of dyslipidemia in clinical medicine. An Executive Summary of those recommendations was previously published. This document provides support for the recommendations outlined in the Executive Summary.

Efficacy and safety of alirocumab in high cardiovascular risk patients with inadequately controlled hypercholesterolaemia on maximally tolerated doses of statins: the ODYSSEY COMBO II randomized controlled trial.

Aims: To compare the efficacy [low-density lipoprotein cholesterol (LDL-C) lowering] and safety of alirocumab, a fully human monoclonal antibody to proprotein convertase subtilisin/kexin 9, compared with ezetimibe, as add-on therapy to maximally tolerated statin therapy in high cardiovascular risk patients with inadequately controlled hypercholesterolaemia.

Methods And Results: COMBO II is a double-blind, double-dummy, active-controlled, parallel-group, 104-week study of alirocumab vs. ezetimibe.

National Lipid Association recommendations for patient-centered management of dyslipidemia: part 1 - executive summary.

Various organizations and agencies have issued recommendations for the management of dyslipidemia. Although many commonalities exist among them, material differences are present as well. The leadership of the National Lipid Association (NLA) convened an Expert Panel to develop a consensus set of recommendations for patient-centered management of dyslipidemia in clinical medicine.

Safety and efficacy of a monoclonal antibody to proprotein convertase subtilisin/kexin type 9 serine protease, SAR236553/REGN727, in patients with primary hypercholesterolemia receiving ongoing stable atorvastatin therapy.

Objectives: The primary objective of this study was to evaluate the low-density lipoprotein cholesterol (LDL-C)-lowering efficacy of 5 SAR236553/REGN727 (SAR236553) dosing regimens versus placebo at week 12 in patients with LDL-C ≥100 mg/dl on stable atorvastatin therapy. Secondary objectives included evaluation of effects on other lipid parameters and the attainment of LDL-C treatment goals of <100 mg/dl (2.59 mmol/l) and <70 mg/dl (1.

Effect of drugs on high-density lipoprotein.

The National Cholesterol Education Program Adult Treatment Panel III found evidence for raising high-density lipoprotein cholesterol (HDL-C) to reduce coronary artery disease (CAD) events supports use of HDL-C to help modify low-density lipoprotein cholesterol (LDL-C)-lowering goals, but not to establish new HDL-C-focused treatment recommendations. However, the HDL-C-raising clinical trials provide important lessons to help guide clinical management of dyslipidemic patients. The fibrate outcome trials demonstrate that these drugs reduce CAD events, but not death.

Pharmacologic options for aggressive low-density lipoprotein cholesterol lowering: benefits versus risks.

Lessons from recent end point trials of lipid-lowering drugs indicate that patients at very high risk for coronary artery disease (CAD) benefit from treatment that lowers low-density lipoprotein (LDL) cholesterol plasma levels to < or = 1.81 mmol/L (< or = 70 mg/dL), that patients with > or = 2 risk factors benefit from treatment that lowers plasma LDL cholesterol to <2.59 mmol/L (<100 mg/dL), and that a significant reduction in CAD event rates is most often associated with a minimum plasma LDL cholesterol reduction of 30%.

Optimizing LDL-C lowering with statins.

Clinical studies have demonstrated the efficacy of statins in reducing low-density lipoprotein cholesterol (LDL-C) and lowering coronary heart disease risk. However, many patients receiving statin therapy in clinical practice are not achieving their LDL-C goals. Generally, statins are initiated at starting doses, and doses should be titrated as needed until the goal of therapy is achieved or a second lipid-lowering drug is required; titration is required in the majority of patients who receive less efficacious agents.
