BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death in Europe and increased low-density lipoprotein cholesterol (LDL-C) is a major contributor to CVD risk. Extensive evidence from clinical studies of statins has demonstrated a linear relationship between LDL-C levels and CVD risk. It has been proposed that lower LDL-C levels than those currently recommended may provide additional clinical benefit to patients. AIM: This review summarises the genetic and clinical evidence on the efficacy and safety of achieving very low LDL-C levels...

Previous individual trials of alirocumab (a PCSK9 monoclonal antibody) showed significant low-density lipoprotein cholesterol reductions with overall treatment-emergent adverse event (TEAE) rates comparable with controls. This analysis evaluated safety data from 14 trials (4 phase 2 and 10 phase 3, 8 to 104 weeks; n = 5,234), in 2 pools according to control (placebo/ezetimibe). Overall, 3,340 patients received alirocumab (4,029 patient-years' exposure), 1,276 received placebo, and 618 received ezetimibe. Incidence of deaths, serious TEAEs, discontinuations because of TEAEs, and overall TEAEs were similar between alirocumab and control groups...

In this article, we consider the new drugs approved for the European market in 2015. We present a summary of the new mechanisms of action introduced and highlight three new mechanisms of action with a potentially high future impact: PCSK9 inhibition (alirocumab (Praluent®) and evolocumab (Repatha®)) for hypercholesterolaemia, neprilysin inhibition (sacubitril in combination with valsartan (Entresto®)) for heart failure, and interleukin-5 inhibition (mepolizumab (Nucala®)) for asthma.

Xanthelasmas are superficial fat deposits around the eyelids commonly present in different hyperlipidemias and associated with increased cardiovascular risk. Statins or other lipid-lowering treatments do not usually modify them. We present the case of a middle-age man with severe high levels of LDL cholesterol from youth due to a genetically defined heterozygous familiar hypercholesterolemia (HeFH). He presented large xanthelasmas of both inner eyelids in spite of long term treatment with statins and ezetimibe that disappeared after treatment with alirocumab75 mg every 2 weeks for 26 months...

Proprotein convertase subtilisin/kexin type 9 (PCSK9) plays an integral role in the degradation of low-density lipoprotein receptors (LDL-R), making it an intriguing target for emerging pharmacotherapy. Two PCSK9 inhibitors, alirocumab and evolocumab, have been approved and are available in the United States and European Union. However, much of the PCSK9 story remains to be told. The pipeline for additional pharmacotherapy options is rich with several compounds under development, using alternative strategies for inhibiting PCSK9...

PURPOSE OF REVIEW: Proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors are promising therapies that inhibit the degradation of low-density lipoprotein (LDL) receptors in the hepatocyte and thus increase LDL cholesterol (LDL-C) uptake from the blood. This review summarizes main findings in the field of PCSK9 inhibitors, from basic mechanism to clinical studies, and aims to provide a contemporary and practical overview of the clinical implication and future directions with PCSK9 inhibitors...

Hypercholesterolemia is one of the main risk factors for atherosclerosis and cardiovascular diseases. The treatment is based on the modification of the diet and lifestyle and if necessary on a pharmacological therapy. The most widely used drugs are the inhibitors of 3-hydroxy-3-methyl-glutaryl coenzyme A reductase (statins); nevertheless, many patients do not reach optimal levels of low-density lipoprotein-cholesterol (LDL-C) even with maximal dosage of statins (eventually associated to ezetimibe) or present side effects, which do not allow them to continue the treatment...

BACKGROUND AND AIMS: In previous phase III studies, the PCSK9 monoclonal antibody alirocumab was administered at doses of 75 or 150 mg every 2 weeks (Q2W). CHOICE I (NCT01926782) evaluated 300 mg every 4 weeks (Q4W) in patients on either maximally tolerated statin or no statin, both ± other lipid-lowering therapies. METHODS: CHOICE I included patients with hypercholesterolemia at moderate-to-very-high cardiovascular risk. Patients were randomized to alirocumab 300 mg Q4W, 75 mg Q2W (calibrator arm), or placebo for 48 weeks, with dose adjustment for either alirocumab arm to 150 mg Q2W at Week (W) 12 if at W8 LDL-C levels were >70/100 mg/dL (1...

BACKGROUND: The PCSK9 antibody alirocumab (75 mg every 2 weeks; Q2W) as monotherapy reduced low-density lipoprotein-cholesterol (LDL-C) levels by 47%. Because the option of a monthly dosing regimen is convenient, ODYSSEY CHOICE II evaluated alirocumab 150 mg Q4W in patients with inadequately controlled hypercholesterolemia and not on statin (majority with statin-associated muscle symptoms), receiving treatment with fenofibrate, ezetimibe, or diet alone. METHODS AND RESULTS: Patients were randomly assigned to placebo, alirocumab 150 mg Q4W or 75 mg Q2W (calibrator arm), with dose adjustment to 150 mg Q2W at week (W) 12 if W8 predefined LDL-C target levels were not met...

Although many clinical trials and meta-analyses have demonstrated that lower serum low-density lipoprotein cholesterol (LDL-C) levels are associated with proportionately greater reductions in the risk of cardiovascular disease events, not all patients with hypercholesterolemia are able to attain risk-stratified LDL-C goals with statin monotherapy. Elucidation of the pathophysiology of genetic disorders of lipid metabolism (e.g., familial hypercholesterolemia) has led to the development of several novel lipid-lowering strategies, including blocking the degradation of hepatic LDL-C receptors that are important in LDL-C clearance, or the inhibition of apoprotein synthesis and lipidation...

PURPOSE: Even with statins and other lipid-lowering therapy (LLT), many patients with heterozygous familial hypercholesterolemia (heFH) continue to have elevated low-density lipoprotein cholesterol (LDL-C) levels. ODYSSEY HIGH FH (NCT01617655) assessed the efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 monoclonal antibody, versus placebo in patients with heFH and LDL-C ≥ 160 mg/dl despite maximally tolerated statin ± other LLT. METHODS: Patients were randomized to subcutaneous alirocumab 150 mg or placebo every 2 weeks (Q2W) for 78 weeks...

OBJECTIVES: Despite maximally tolerated statin therapy, many patients with high cardiovascular risk, with or without heterozygous familial hypercholesterolemia may require additional low-density lipoprotein cholesterol (LDL-C) reduction. We report pooled alirocumab (ALI) efficacy and safety data from eight Phase 3 trials in 4629 hypercholesterolemia patients, receiving background statin therapy. MATERIAL AND METHODS: Studies were pooled by ALI dose and control: ALI 75/150mg every 2weeks (Q2W; dose increased to 150mg Q2W at Week 12 based on Week 8 LDL-C) versus ezetimibe (EZE; Pool 1) or placebo (PBO; Pool 2), and ALI 150mg Q2W versus PBO (Pool 3)...

AIM: To evaluate the effect of alirocumab on frequency of standard apheresis treatments [weekly or every 2 weeks (Q2W)] in heterozygous familial hypercholesterolaemia (HeFH). METHODS AND RESULTS: ODYSSEY ESCAPE (NCT02326220) was a double-blind study in 62 HeFH patients undergoing regular weekly or Q2W lipoprotein apheresis. Patients were randomly assigned (2:1, respectively) to receive alirocumab 150 mg (n = 41) or placebo (n = 21) Q2W subcutaneously for 18 weeks...

Control of lipid levels is one of the most effective strategies for cardiovascular (CV) event prevention. In fact, many clinical trials have clearly demonstrated that low-density lipoprotein cholesterol (LDL-C) lowering, primarily with statins, reduces major CV events and mortality. The evidence from these trials has been useful in designing the cholesterol treatment guidelines, which are mainly aimed at preventing and managing cardiovascular disease (CVD). However, available data indicate that a large proportion of patients fail to achieve lipid goals, and this is particularly frequent in patients at high or very high CV risk...
