BackgroundWe sought to examine the efficacy and safety of 2 PCSK9 (proprotein convertase subtilisin/kexin type 9) inhibitors: alirocumab and evolocumab.Methods and ResultsWe performed a systematic review and meta‐analysis of randomized controlled trials comparing treatment with and without PCSK9 inhibitors; 35 randomized controlled trials comprising 45 539 patients (mean follow‐up: 85.5 weeks) were included. Mean age was 61.0±2.8 years, and mean baseline low‐density lipoprotein cholesterol was 106±22 mg/dL. Compared with no PCSK9 inhibitor therapy, treatment with a PCSK9 inhibitor was associated with a lower rate of myocardial infarction (2.3% versus 3.6%; odds ratio [OR]: 0.72 [95% confidence interval (CI), 0.64–0.81]; P<0.001), stroke (1.0% versus 1.4%; OR: 0.80 [95% CI, 0.67–0.96]; P=0.02), and coronary revascularization (4.2% versus 5.8%; OR: 0.78 [95% CI, 0.71–0.86]; P<0.001). Overall, no significant change was observed in all‐cause mortality (OR: 0.71 [95% CI, 0.47–1.09]; P=0.12) or cardiovascular mortality (OR: 1.01 [95% CI, 0.85–1.19]; P=0.95). A significant association was observed between higher baseline low‐density lipoprotein cholesterol and benefit in all‐cause mortality (P=0.038). No significant change was observed in neurocognitive adverse events (OR: 1.12 [95% CI, 0.88–1.42]; P=0.37), myalgia (OR: 0.95 [95% CI, 0.75–1.20]; P=0.65), new onset or worsening of preexisting diabetes mellitus (OR: 1.05 [95% CI, 0.95–1.17]; P=0.32), and increase in levels of creatine kinase (OR: 0.84 [95% CI, 0.70–1.01]; P=0.06) or alanine or aspartate aminotransferase (OR: 0.96 [95% CI, 0.82–1.12]; P=0.61).ConclusionsTreatment with a PCSK9 inhibitor is well tolerated and improves cardiovascular outcomes. Although no overall benefit was noted in all‐cause or cardiovascular mortality, such benefit may be achievable in patients with higher baseline low‐density lipoprotein cholesterol.

BackgroundIn statin trials, men and women derived similar relative risk reductions in cardiovascular events per 39 mg/dL low‐density lipoprotein cholesterol (LDL‐C) reduction. We explored whether lower LDL‐C levels and greater LDL‐C percentage reductions than those achieved with statins are associated with reduced major adverse cardiovascular event (MACE) rates in women as well as men.Methods and ResultsData pooled from 10 phase 3 ODYSSEY randomized trials (n=4983) comparing alirocumab with control (placebo/ezetimibe) were assessed for association between 39 mg/dL lower on‐treatment LDL‐C and percentage LDL‐C change from baseline, and MACE risk by sex, using multivariable Cox regression. Mean baseline LDL‐C was 135 mg/dL (women) and 121 mg/dL (men). Average on‐treatment LDL‐C levels with alirocumab, ezetimibe, and placebo were 71, 114, and 134 mg/dL, respectively, in women (n=1882) and 52, 93, and 122 mg/dL, respectively, in men (n=3090). Overall, 36.5% and 58.7% of women and men, respectively, achieved on‐treatment LDL‐C <50 mg/dL. Each 39 mg/dL lower LDL‐C was associated with a 33% and 22% lower risk of MACE in women (P=0.0209) and men (P=0.0307), respectively, with no significant between‐sex difference (P for heterogeneity=0.4597). Results were similar when analyzed per 50% LDL‐C reduction, 24% (P=0.1094) and 29% (P=0.0125) lower MACE risk in women and men, respectively (P for heterogeneity=0.7499). Alirocumab was generally well tolerated in both sexes.ConclusionsThe present analysis reinforces the notion that both sexes derive a similar cardiovascular benefit from LDL‐C lowering. Although women had slightly higher on‐treatment LDL‐C than men, both sexes showed a similar lower MACE risk with lower LDL‐C.

“…Alirocumab, a fully human monoclonal antibody that specifically binds to PCSK9, has been shown to significantly lower LDL‐C levels across a range of dosing regimens, whether as monotherapy12 or on a background of statin±other lipid‐lowering therapies 13, 14, 15, 16. A monthly dosing regimen may be convenient and effective,17, 18 with different doses being appropriate when used as monotherapy compared with background statin therapy.…”

“…This study also employed an alirocumab dosing regimen of 75 mg every 2 weeks (Q2W; with possible dose adjustment to 150 mg Q2W; referred to as “75Q2W”) as a calibrator arm, a dose that has been extensively investigated across the phase 3 ODYSSEY clinical trials program 12, 13, 14, 15, 16. CHOICE II followed a “treat‐to‐target” dosing strategy, based on the LDL‐C reduction needed to provide best achievement of target LDL‐C level at the lowest alirocumab dose.…”

BackgroundThe 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 ResultsPatients 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. The primary efficacy endpoint was LDL‐C percentage change from baseline to W24. Mean baseline LDL‐C levels were 163.9 mg/dL (alirocumab 150 mg Q4W, n=59), 154.5 mg/dL (alirocumab 75 mg Q2W, n=116), and 158.5 mg/dL (placebo, n=58). In the alirocumab 150 mg Q4W and 75 mg Q2W groups (49.1% and 36.0% of patients received dose adjustment, respectively), least‐squares mean LDL‐C changes from baseline to W24 were −51.7% and −53.5%, respectively (placebo [+4.7%]; both groups P<0.0001 versus placebo). In total, 63.9% and 70.3% of alirocumab‐treated patients achieved their LDL‐C targets at W24. Treatment‐emergent adverse events occurred in 77.6% (alirocumab 150 mg Q4W), 73.0% (alirocumab 75 mg Q2W), and 63.8% (placebo) of patients, with injection‐site reactions among the most common treatment‐emergent adverse events.ConclusionsAlirocumab 150 mg Q4W can be considered in patients not on statin with inadequately controlled hypercholesterolemia as a convenient option for lowering LDL‐C.Clinical Trial Registration URL: http://www.clinicaltrials.gov.

Monotherapy with the PCSK9 inhibitor alirocumab versus ezetimibe in patients with hypercholesterolemia: Results of a 24week, double-blind, randomized Phase 3 trial

Abstract: Alirocumab demonstrated significantly greater LDL-C lowering versus ezetimibe after 24 weeks with the lower 75 mg Q2W dose sufficient to provide ≥ 50% LDL-C reduction in the majority of the patients. Adverse events were comparable between groups.
