Inclisiran administration potently and durably lowers LDL-C over an extended-term follow-up: the ORION-8 trial.

BACKGROUND AND AIMS: Data describing the long-term efficacy, safety, and tolerability of inclisiran are limited. This was explored in ORION-8, an open-label extension study of preceding Phase 2 and Phase 3 placebo-controlled and open-label extension trials. METHODS: Adults with ASCVD, ASCVD risk equivalent, or HeFH received open-label inclisiran every 180 days (after completion of the parent trial) until Day 990, followed by an end-of-study (EOS) visit at Day 1080 or ≥90 days after last dose. Study endpoints included proportion of patients achieving pre-specified LDL-C goals (ASCVD: <1.8 mmol/L [<70 mg/dL]; ASCVD risk equivalent: <2.6 mmol/L [<100 mg/dL]), percentage and absolute changes in LDL-C at EOS, and safety of inclisiran. RESULTS: Of 3274 patients included in the analysis, 2446 (74.7%) were followed until EOS. Mean age was 64.9±9.9 years, 82.7% (n=2709) had ASCVD, and mean baseline LDL-C was 2.9±1.2 mmol/L. Mean cumulative exposure to inclisiran (including parent trials) was 3.7 years; maximum exposure was 6.8 years. With inclisiran, 78.4% (95% CI: 76.8, 80.0) of patients achieved pre-specified LDL-C goals and mean percentage LDL-C reduction was -49.4% (95% CI: -50.4, -48.3). No attenuation of LDL-C lowering over time was observed. Treatment-emergent adverse events at the injection site (all mild or moderate) occurred in 5.9% of inclisiran-treated patients. Inclisiran-associated anti-drug antibodies were infrequent (5.5%) and had no impact on the efficacy or safety of inclisiran. No new safety signals were identified. CONCLUSIONS: In the largest and longest follow-up to date, inclisiran demonstrated sustained and substantial LDL-C lowering with a favourable long-term safety and tolerability profile.

Inclisiran in individuals with diabetes or obesity: Post hoc pooled analyses of the ORION-9, ORION-10 and ORION-11 Phase 3 randomized trials.

AIMS: To conduct a pooled analysis of Phase 3 trials investigating the efficacy and safety of inclisiran across glycaemic and body mass index (BMI) strata. MATERIALS AND METHODS: Participants were randomized 1:1 to receive 300 mg inclisiran sodium or placebo twice yearly, after initial and 3-month doses up to 18 months, with background oral lipid-lowering therapy. Analyses were stratified by glycaemic status (normoglycaemia, prediabetes, and diabetes) or BMI (<25, ≥25 to <30, ≥30 to <35, and ≥35 kg/m2). Co-primary endpoints were percentage and time-adjusted percentage change in low-density lipoprotein (LDL) cholesterol from baseline. Safety was also assessed. RESULTS: Baseline characteristics were balanced between treatment arms and across strata. Percent LDL cholesterol change (placebo-corrected) with inclisiran from baseline to Day 510 ranged from -47.6% to -51.9% and from -48.8% to -54.4% across glycaemic/BMI strata, respectively. Similarly, time-adjusted percentage changes after Day 90 and up to Day 540 ranged from -46.8% to -52.0% and from -48.6% to -53.3% across glycaemic/BMI strata, respectively. Inclisiran led to significant reductions in proprotein convertase subtilisin/kexin type 9 and other atherogenic lipids and lipoproteins versus placebo across the glycaemic/BMI strata. The proportions of individuals achieving LDL cholesterol thresholds of <1.8 mmol/L and <1.4 mmol/L with inclisiran increased with increasing glycaemic and BMI strata. Across the glycaemic/BMI strata, a higher proportion of individuals had mild/moderate treatment-emergent adverse events (TEAEs) at the injection site with inclisiran (2.8%-7.7%) versus placebo (0.2%-2.1%). CONCLUSION: Inclisiran provided substantial and sustained LDL cholesterol lowering across glycaemic/BMI strata, with a modest excess of transient mild-to-moderate TEAEs at the injection site.

Obicetrapib on Top of Maximally Tolerated Lipid-Modifying Therapies in Participants With or at High Risk for Atherosclerotic Cardiovascular Disease: Rationale and Designs of BROADWAY and BROOKLYN.

Obicetrapib, a novel, selective cholesteryl ester transfer protein (CETP) inhibitor, reduces low-density lipoprotein cholesterol (LDL-C), LDL particles, apolipoprotein (Apo) B, and lipoprotein(a) [Lp(a)] and increases high-density lipoprotein cholesterol (HDL-C) when added to statins with or without ezetimibe. By substantially reducing LDL-C, obicetrapib has the potential to lower atherogenic lipoproteins in patients with atherosclerotic cardiovascular disease (ASCVD) or heterozygous familial hypercholesterolemia (HeFH) whose LDL-C levels remain high despite treatment with available maximally tolerated lipid-modifying therapies, addressing an unmet medical need in a patient population at high risk for cardiovascular events. BROADWAY (NCT05142722) and BROOKLYN (NCT05425745) are ongoing placebo-controlled, double-blind, randomized Phase III trials designed to examine the efficacy, safety, and tolerability of obicetrapib as an adjunct to dietary intervention and maximally tolerated lipid-modifying therapies in participants with a history of ASCVD and/or underlying HeFH whose LDL-C is not adequately controlled. The primary efficacy endpoint was the percent change in LDL-C from baseline to day 84. Other endpoints included changes in Apo B, non-HDL-C, HDL-C, Apo A1, Lp(a) and triglycerides in addition to parameters evaluating safety, tolerability, and pharmacokinetics. BROADWAY also included an adjudicated assessment of major adverse cardiovascular events, measurements of glucose homeostasis, and an ambulatory blood pressure monitoring substudy. A total of 2532 participants were randomized in BROADWAY and 354 in BROOKLYN to receive obicetrapib 10 mg or placebo (2:1) for 365 days with follow-up through 35 days after the last dose. Results from both trials are anticipated in 2024. These trials will provide safety and efficacy data to support the potential use of obicetrapib among patients with ASCVD or HeFH with elevated LDL-C for whom existing therapies are not sufficiently effective or well-tolerated.

Cardiovascular outcomes in patients with homozygous familial hypercholesterolaemia on lipoprotein apheresis initiated during childhood: long-term follow-up of an international cohort from two registries.

BACKGROUND: Homozygous familial hypercholesterolaemia (HoFH) is a rare genetic disease characterised by extremely high plasma LDL cholesterol from birth, causing atherosclerotic cardiovascular disease at a young age. Lipoprotein apheresis in combination with lipid-lowering drugs effectively reduce LDL cholesterol, but long-term health outcomes of such treatment are unknown. We aimed to investigate the long-term cardiovascular outcomes associated with lipoprotein apheresis initiated in childhood or adolescence. METHODS: In this cohort study, data were drawn from the HoFH International Clinical Collaboration (HICC) and the international registry for Children with Homozygous Hypercholesterolemia on Lipoprotein Apheresis (CHAIN). An overall cohort included patients diagnosed with HoFH aged 0-18 years who were alive and in follow-up between Jan 1, 2010, and Nov 8, 2021, and whose high plasma LDL cholesterol concentrations made them eligible for lipoprotein apheresis. To compare cardiovascular outcomes, patients who initiated lipoprotein apheresis in childhood (lipoprotein apheresis group) and patients who only received lipid-lowering drugs (pharmacotherapy-only group) were matched by sex and untreated plasma LDL cholesterol concentrations. The primary outcome was a composite of cardiovascular death, myocardial infarction, ischaemic stroke, percutaneous coronary intervention, coronary artery bypass grafting, aortic valve replacement, peripheral artery disease, carotid endarterectomy, angina pectoris, and supra-aortic or aortic stenosis (collectively referred to as atherosclerotic cardiovascular disease), for which survival analyses were performed in the matched cohort. Cox regression analyses were used to compare disease-free survival between cohorts and to calculate hazard ratio (HR) and 95% CI adjusted for sex, age at diagnosis, untreated plasma LDL cholesterol concentration, and number of lipid-lowering therapies other than lipoprotein apheresis. FINDINGS: The overall cohort included 404 patients with a median age at diagnosis of 6·0 years (IQR 3·0-9·5) and median untreated plasma LDL cholesterol of 17·8 mmol/L (14·7-20·8). The matched cohorts included 250 patients (125 patients per group), with a median untreated LDL cholesterol of 17·2 mmol/L (14·8-19·7). Mean reduction in plasma LDL cholesterol concentrations between baseline and final follow-up was greater in the lipoprotein apheresis group (-55% [95% CI -60 to -51] vs -31% [-36 to -25]; p<0·0001). Patients in the lipoprotein apheresis group had longer atherosclerotic cardiovascular disease-free survival (adjusted HR 0·52 [95% CI 0·32-0·85]) and longer cardiovascular death-free survival (0·0301 [0·0021-0·4295]). Cardiovascular death was more common in the pharmacotherapy-only group than in the lipoprotein apheresis group (ten [8%] vs one [1%]; p=0·010), whereas median age at coronary artery bypass grafting was lower in the lipoprotein apheresis group than in the pharmacotherapy-only group (15·0 years [IQR 12·0-24·0] vs 30·5 years [19·0-33·8]; p=0·037). INTERPRETATION: Among patients with HoFH, lipoprotein apheresis initiated during childhood and adolescence is associated with reduced long-term risk of atherosclerotic cardiovascular disease and death, and clear benefits of early initiation of high-frequency treatment on reducing plasma cholesterol were found. Consensus recommendations are now needed to guide more widespread and timely use of lipoprotein apheresis for children with HoFH, and research is required to further optimise treatment and ensure benefits of early and aggressive treatment delivery are balanced against effects on quality of life.

Atherosclerosis evaluation and cardiovascular risk estimation using coronary computed tomography angiography.

Clinical risk scores based on traditional risk factors of atherosclerosis correlate imprecisely to an individual's complex pathophysiological predisposition to atherosclerosis and provide limited accuracy for predicting major adverse cardiovascular events (MACE). Over the past two decades, computed tomography scanners and techniques for coronary computed tomography angiography (CCTA) analysis have substantially improved, enabling more precise atherosclerotic plaque quantification and characterization. The accuracy of CCTA for quantifying stenosis and atherosclerosis has been validated in numerous multicentre studies and has shown consistent incremental prognostic value for MACE over the clinical risk spectrum in different populations. Serial CCTA studies have advanced our understanding of vascular biology and atherosclerotic disease progression. The direct disease visualization of CCTA has the potential to be used synergistically with indirect markers of risk to significantly improve prevention of MACE, pending large-scale randomized evaluation.

Estimating potential cardiovascular health benefits of improved population level control of LDL cholesterol through a twice-yearly siRNA-based approach: A simulation study of a health-system level intervention.

BACKGROUND AND AIMS: Inclisiran, an siRNA therapy, consistently reduces low-density lipoprotein cholesterol (LDL-C) with twice-yearly dosing. Potential cardiovascular benefits of implementing inclisiran at a population level, added to statins, were evaluated through simulation. METHODS: For each participant in the ORION-10 and ORION-11 trials comparing inclisiran with placebo, baseline 10-year cardiovascular risk was estimated using the SMART equation. The time-adjusted LDL-C difference from baseline observed 90-540 days after baseline was assumed to persist and used to estimate potential reduction in 10-year cardiovascular risk. Impact on 500,000 ORION-like individuals was simulated with Monte-Carlo. RESULTS: Mean baseline LDL-C and predicted 10-year major vascular risk among patients randomized to inclisiran (n = 1288) versus placebo (n = 1264) were 2.66 mmol/L versus 2.60 mmol/L and 24.9% versus 24.6%, respectively. Placebo-corrected time-adjusted absolute reduction in LDL-C with inclisiran was -1.32 mmol/L (95% CI -1.37 to -1.26; p < 0.001), which predicted a 10-year cardiovascular risk of 18.1% with inclisiran versus 24.7% with placebo (absolute difference [95% CI], -6.99% [-7.33 to -6.66]; p < 0.001) NNT 15. Extrapolating to 500,000 inclisiran-treated individuals, the model predicted large population shifts towards lower quintiles of risk with fewer remaining in high-risk categories; 3350 to 471 (≥80% risk), 11,793 to 3332 (60-<80% risk), 52,142 to 22,665 (40-<60% risk), 197,752 to 141,014 (20-<40% risk), and more moving into the lowest risk category (<20%) from 234,963 to 332,518. CONCLUSIONS: Meaningful gains in population health might be achieved over 10 years by implementing at-scale approaches capable of providing substantial and sustained reductions in LDL-C beyond those achievable with statins.

CVOT Summit Report 2023: new cardiovascular, kidney, and metabolic outcomes.

The 9th Cardiovascular Outcome Trial (CVOT) Summit: Congress on Cardiovascular, Kidney, and Metabolic Outcomes was held virtually on November 30-December 1, 2023. This reference congress served as a platform for in-depth discussions and exchange on recently completed outcomes trials including dapagliflozin (DAPA-MI), semaglutide (SELECT and STEP-HFpEF) and bempedoic acid (CLEAR Outcomes), and the advances they represent in reducing the risk of major adverse cardiovascular events (MACE), improving metabolic outcomes, and treating obesity-related heart failure with preserved ejection fraction (HFpEF). A broad audience of endocrinologists, diabetologists, cardiologists, nephrologists and primary care physicians participated in online discussions on guideline updates for the management of cardiovascular disease (CVD) in diabetes, heart failure (HF) and chronic kidney disease (CKD); advances in the management of type 1 diabetes (T1D) and its comorbidities; advances in the management of CKD with SGLT2 inhibitors and non-steroidal mineralocorticoid receptor antagonists (nsMRAs); and advances in the treatment of obesity with GLP-1 and dual GIP/GLP-1 receptor agonists. The association of diabetes and obesity with nonalcoholic steatohepatitis (NASH; metabolic dysfunction-associated steatohepatitis, MASH) and cancer and possible treatments for these complications were also explored. It is generally assumed that treatment of chronic diseases is equally effective for all patients. However, as discussed at the Summit, this assumption may not be true. Therefore, it is important to enroll patients from diverse racial and ethnic groups in clinical trials and to analyze patient-reported outcomes to assess treatment efficacy, and to develop innovative approaches to tailor medications to those who benefit most with minimal side effects. Other keys to a successful management of diabetes and comorbidities, including dementia, entail the use of continuous glucose monitoring (CGM) technology and the implementation of appropriate patient-physician communication strategies. The 10th Cardiovascular Outcome Trial Summit will be held virtually on December 5-6, 2024 ( http://www.cvot.org ).

An update on inclisiran for the treatment of elevated LDL cholesterol.

INTRODUCTION: The burden of atherosclerotic cardiovascular disease (ASCVD) persists globally, demanding innovative therapeutic strategies. This manuscript provides an expert opinion on the significance of managing low-density lipoprotein cholesterol in ASCVD prevention and introduces inclisiran, a novel small interfering RNA targeting proprotein convertase subtilisin/kexin type 9 (PCSK9). AREAS COVERED: This work delves into the intricate mechanism of inclisiran, highlighting its unique approach of hepatic intracellular PCSK9 inhibition, its precision and low off-target effects risk. Pharmacodynamic and pharmacokinetic distinctions from PCSK9 monoclonal antibodies are explored, underlining inclisiran's efficiency, extended duration, and clearance. Clinical trials, including pivotal phase-III placebo-controlled studies (ORION-9, -10, -11), the open-label ORION-3 and pooled safety analysis of these trails including the open-label phase of ORION-8, as well as real-word data are discussed to provide a comprehensive evaluation of inclisiran's efficacy and safety. EXPERT OPINION: Inclisiran stands as a first-in-class breakthrough in lipid-lowering therapies, showing potential in alleviating the global burden of ASCVD and is supported by multiple global regulatory approvals. To optimize inclisiran's utilization and comprehend its long-term effects, future directions include pediatric studies, cardiovascular outcome trials, and extended-duration investigations. Overall, inclisiran emerges as a precise and effective therapeutic option, offering significant promise for preserving cardiovascular health.

Impact of the 2021 European Society for Cardiology prevention guideline's stepwise approach for cardiovascular risk factor treatment in patients with established atherosclerotic cardiovascular disease.

AIMS: This study aimed to evaluate the stepwise approach for cardiovascular (CV) risk factor treatment as outlined by the European Society for Cardiology 2021 guidelines on CV disease (CVD) prevention in patients with established atherosclerotic CVD (ASCVD). METHODS AND RESULTS: In patients with ASCVD, included in UCC-SMART (n = 8730) and European parts of the REACH registry (n = 18 364), the 10-year CV risk was estimated using SMART2. Treatment effects were derived from meta-analyses and trials. Step 1 recommendations were LDL cholesterol (LDLc) < 1.8 mmol/L, systolic blood pressure (SBP) < 140 mmHg, using any antithrombotic medication, sodium-glucose co-transporter 2 (SGLT2) inhibition, and smoking cessation. Step 2 recommendations were LDLc < 1.4 mmol/L, SBP < 130 mmHg, dual-pathway inhibition (DPI, aspirin plus low-dose rivaroxaban), colchicine, glucagon-like peptide (GLP)-1 receptor agonists, and eicosapentaenoic acid. Step 2 was modelled accounting for Step 1 non-attainment. With current treatment, residual CV risk was 22%, 32%, and 60% in the low, moderate, and pooled (very) high European risk regions, respectively. Step 2 could prevent up to 198, 223 and 245 events per 1000 patients treated, respectively. Intensified LDLc reduction, colchicine, and DPI could be applied to most patients, preventing up to 57, 74, and 59 events per 1000 patients treated, respectively. Following Step 2, the number of patients with a CV risk of <10% could increase from 20%, 6.4%, and 0.5%, following Step 1, to 63%, 48%, and 12%, in the respective risk regions. CONCLUSION: With current treatment, residual CV risk in patients with ASCVD remains high across all European risk regions. The intensified Step 2 treatment options result in marked further reduction of residual CV risk in patients with established ASCVD. KEY FINDINGS: Guideline-recommended intensive treatment of patients with cardiovascular disease could prevent additional 198-245 new cardiovascular events for every 1000 patients treated.

Patients with established cardiovascular disease are at high risk for new cardiovascular events. The European Society of Cardiology guideline for the prevention of cardiovascular disease introduced a stepwise treatment approach. Step 1 in this approach are treatments that apply to all patients, and Step 2 are intensive treatments that can be prescribed to patients who are still at high risk of new events even with Step 1 treatments. The current study investigates the effect of Steps 1 and 2 on the risk of cardiovascular disease in 27 094 patients all across Europe. With the conventional treatments of Step 1 the risk of cardiovascular disease remains high, with a 10-year risk of new events higher than 10% in 80­99% of patients. The intensive treatment options from Step 2 could prevent additional 198­245 new cardiovascular events for every 1000 patients that are treated. With intensive treatment, up to 63% of patients could achieve a 10-year risk of new cardiovascular disease below 10%.

Efficacy and safety of bempedoic acid in patients with heterozygous familial hypercholesterolemia: analysis of pooled patient-level data from phase 3 clinical trials.

BACKGROUND: Patients with heterozygous familial hypercholesterolemia (HeFH) often cannot reach guideline-recommended low-density lipoprotein cholesterol (LDL-C) goals despite multidrug therapy. OBJECTIVE: To evaluate the efficacy and safety of bempedoic acid as an add-on therapy for lowering LDL-C in patients with HeFH. METHODS: Pooled data from two 52-week phase 3 clinical trials of patients with atherosclerotic cardiovascular disease and/or HeFH receiving maximally tolerated statin therapy (randomized 2:1 to bempedoic acid or placebo) were analyzed by HeFH status. Endpoints included changes from baseline to week 12 (and up to week 52) in LDL-C and other lipid parameters, achievement of LDL-C goals, and safety. RESULTS: A total of 217 (bempedoic acid, 146; placebo, 71) patients with HeFH and 2,792 (bempedoic acid, 1,864; placebo, 928) without HeFH were included (mean baseline LDL-C, 172.8 mg/dL and 102.6 mg/dL, respectively). Bempedoic acid significantly lowered LDL-C at week 12 vs. placebo regardless of HeFH status (with HeFH, -21.2%; without HeFH, -18.2% [both P<0.0001]). Bempedoic acid significantly reduced other lipid parameters and high-sensitivity C-reactive protein vs. placebo regardless of HeFH status (all P≤0.01). Among patients with HeFH treated with bempedoic acid, 32% and 27% achieved LDL-C <100 mg/dL at weeks 12 and 52, respectively. Overall treatment-emergent adverse event incidence was comparable across all four groups (74.7-77.5%). CONCLUSION: Bempedoic acid significantly lowered LDL-C levels vs. placebo and was generally well tolerated in all patients, with no new safety findings in patients with HeFH, despite more intensive lipid-lowering therapy in patients with vs. without HeFH.

Impact of Bempedoic Acid on Total Cardiovascular Events: A Prespecified Analysis of the CLEAR Outcomes Randomized Clinical Trial.

Importance: The ATP citrate lyase (ACL) inhibitor, bempedoic acid, reduces low-density lipoprotein cholesterol (LDL-C) level and major adverse cardiovascular events (MACE) by 13% in patients at high cardiovascular risk with intolerance of statin and high-intensity statin medications. The effects of bempedoic acid on total cardiovascular events remain unknown. Objective: To determine the impact of bempedoic acid on the total incidence of MACE. Design, Setting, and Participants: Included in this prespecified analysis of the Cholesterol Lowering via Bempedoic Acid, an ACL-Inhibiting Regimen (CLEAR) Outcomes trial were patients with, or at high risk for, cardiovascular disease, with hypercholesterolemia and inability to take guideline-recommended statins. Study data were analyzed from December 2016 to November 2022. Interventions: Patients were randomly assigned to treatment with bempedoic acid or placebo daily. Main Outcomes and Measures: The primary end point was the time to first event for a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or coronary revascularization (MACE-4). The key secondary end point was time to first event for cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke (MACE-3). This prespecified analysis compared the total number of cardiovascular events in the treatment groups. Results: A total of 13 970 patients (mean [SD] age, 65 [9] years; 7230 male [51.8%]) were included in the study. A total of 9764 participants (69.9%) had prior atherosclerotic cardiovascular disease and a baseline LDL-C level of 139 mg/dL; treatment with bempedoic acid resulted in a 21% reduction in LDL-C level and a 22% reduction in high-sensitivity C-reactive protein (hsCRP) level at 6 months. Median (IQR) follow-up was 3.4 (3.1-3.9) years. A total of 1746 positively adjudicated first MACE-4 events and 915 additional MACE events in 612 patients were recorded, with coronary revascularization representing 32.8% (573 of 1746) of first events and 69.4% (635 of 915) of additional events. For the total incidence of cardiovascular events, treatment with bempedoic acid was associated with a reduction in risk of MACE-4 (hazard ratio [HR], 0.80; 95% CI, 0.72-0.89; P <.001), MACE-3 (HR, 0.83; 95% CI, 0.73-0.93; P = .002), myocardial infarction (HR, 0.69; 95% CI, 0.58-0.83; P < .001), and coronary revascularization (HR, 0.78; 95% CI, 0.68-0.89; P <.001), although no statistically significant difference was observed for stroke (HR, 0.80; 95% CI, 0.63-1.03). A lower HR for protection with bempedoic acid was observed with increasing number of MACE events experienced by patients. Conclusion and Relevance: Lowering LDL-C level with bempedoic acid reduced the total number of cardiovascular events in patients with high cardiovascular risk, statin therapy intolerance, and elevated LDL-C levels.

Evolocumab-Based LDL-C Management in High and Very High Cardiovascular Risk Patients in German Clinical Practice: The HEYMANS Study.

INTRODUCTION: Low-density lipoprotein cholesterol (LDL-C) is among the most important modifiable risk factors for cardiovascular disease. In very high-risk patients, the European Society of Cardiology/European Atherosclerosis Society guidelines recommend attaining LDL-C < 55 mg/dL. In the German cohort of the observational HEYMANS study, we aimed to describe the clinical characteristics and LDL-C control among patients initiating evolocumab. METHODS: Data was collected between 09/2016 and 05/2021 for ≤ 6 months before (retrospectively) and ≤ 30 months after evolocumab initiation (prospectively). Patient characteristics, lipid-lowering therapy (LLT), lipid values, evolocumab use, and safety were collected. RESULTS: Of 380 enrolled patients, 93% received evolocumab in secondary prevention and 69% had a history of statin intolerance. At study baseline, 49% did not receive any statins and LDL-C was very high (145 mg/dL). Use of evolocumab decreased LDL-C by a median of 53% within 3 months and remained stable thereafter, despite mainly unchanged background LLT. Overall, 59% attained an LDL-C level < 55 mg/dL (69% with, 49% without LLT). Persistence to evolocumab was 90.6% in months 1-12 and 93.5% in months 13-30. Adverse drug reactions were reported in 8% of patients. CONCLUSION: Data from the German HEYMANS cohort corroborate previous reports on evolocumab effectiveness and safety in clinical practice. Evolocumab initiation was associated with a rapid and sustained LDL-C reduction. Persistence with evolocumab was high. Our finding that patients receiving an evolocumab/LLT combination are more likely to attain the LDL-C goal than those receiving evolocumab alone corroborates previous data showing the importance of using highly intensive therapy.

Evolocumab use in clinical practice in Switzerland: final data of the observational HEYMANS cohort study.

AIMS: The HEYMANS study observed patients receiving evolocumab as part of routine clinical hyperlipidemia management. It was designed to capture data on clinical parameters relevant to health authorities and physicians. METHODS: This was a European multi-country observational cohort serial chart review study; data on the Swiss cohort are reported here. Patients were prescribed evolocumab as per the Swiss reimbursement criteria in force at the time and were invited chronologically. The study consisted of a 6-month period prior to initiation of evolocumab, a 12-month core observation period (entered by 75 patients, completed by 74 patients), and an 18-month extended observation period (entered by 40 patients, completed by 34 patients). The primary objective was to describe the clinical characteristics of patients receiving evolocumab. Secondary objectives included to describe lipid levels, evolocumab use, and patterns of use of other lipid-lowering therapies (LLT, that is, statins and/or ezetimibe) over time. The study was conducted in the Swiss cohort between May 2017 and June 2021. RESULTS: Patients who received evolocumab in Swiss routine practice mostly were in secondary prevention (93%) and had a history of statin intolerance (85%) with 53% receiving no background LLT. One-third had familial hypercholesterolemia. Patients initiated evolocumab at a median low-density lipoprotein cholesterol (LDL-C) of 3.6 mmol/L, which decreased by 54% within 3 months to 1.6 mmol/L and was stable thereafter. Overall, 61% achieved the LDL-C goal of <1.4 mmol/L with more patients attaining this goal when they received evolocumab with a statin and/or ezetimibe (84%) compared to 41% when receiving evolocumab alone. An LDL-C reduction of ⩾50% was achieved by 85% of patients. Persistence with evolocumab at 12 months was 85%. CONCLUSION: In Swiss clinical practice, evolocumab was mainly prescribed to patients with very high cardiovascular risk, who had very high LDL-C levels. Most patients continued to use evolocumab throughout the study period. In these patients, LDL-C was reduced by >50% within 3 months and LDL-C reductions were maintained over time. Guideline-recommended LDL-C goals for this very high-risk cohort were more frequently attained in patients receiving a combination of statin and/or ezetimibe and evolocumab.

Efficacy and safety of bempedoic acid among patients with and without diabetes: prespecified analysis of the CLEAR Outcomes randomised trial.

BACKGROUND: Statins reduce LDL cholesterol and cardiovascular events among those with or without diabetes but have been reported to increase new-onset diabetes. The CLEAR Outcomes trial demonstrated that bempedoic acid reduced the risk of major adverse cardiovascular events among statin-intolerant patients at high cardiovascular risk. In this prespecified analysis, our dual aims were to evaluate the cardiovascular benefits of bempedoic acid, an ATP-citrate lyase inhibitor, in individuals with diabetes, and to evaluate the risk of new-onset diabetes and HbA1c among those without diabetes in the CLEAR Outcomes trial. METHODS: CLEAR Outcomes was a randomised, double-blind, placebo-controlled trial conducted across 1250 primary care and outpatient sites in 32 countries. Patients with or without cardiovascular disease who were unwilling or unable to take guideline-recommended doses of statins and an LDL cholesterol of 2·59 mmol/L or more were randomly assigned (1:1) in a double-blinded manner to either bempedoic acid 180 mg once per day or placebo. In this prespecified analysis, the efficacy endpoint was a time-to-event analysis of four-component major adverse cardiovascular event (MACE-4), which is the composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or coronary revascularisation, using the intention-to-treat population stratified by baseline glycaemia status. The prespecified analysis of risk of new-onset diabetes and HbA1c increase was evaluated in patients without diabetes at baseline. The CLEAR Outcomes trial was completed on Nov 7, 2022, and is registered with ClinicalTrials.gov (NCT02993406). FINDINGS: Between Dec 22, 2016, and Nov 7, 2022, 13 970 patients were screened and randomly assigned; 6373 (45·6%) with diabetes, 5796 (41·5%) with prediabetes, and 1801 (12·9%) with normoglycaemia. Over a median of 3·4 years follow up, patients with diabetes had significant relative and absolute cardiovascular risk reductions in MACE-4 endpoints with bempedoic acid (HR 0·83; 95% CI 0·72-0·95; absolute risk reduction of 2·4%) compared to placebo, with no statistical evidence of effect modification across glycaemic strata (interaction p=0·42). The proportion of patients who developed new-onset diabetes were similar between the bempedoic acid and placebo groups, with 429 of 3848 (11·1%) with bempedoic acid versus 433 of 3749 (11·5%) with placebo (HR 0·95; 95% CI 0·83-1·09). HbA1c concentrations at month 12 and the end of the study were similar between randomised groups in patients who had prediabetes and normoglycaemia. Placebo-corrected LDL cholesterol concentrations and high-sensitivity C-reactive protein at 6 months were reduced in each glycaemic stratum (diabetes, prediabtes, and normoglycaemia) for patients randomly assigned to bempedoic acid (all p<0·001). INTERPRETATION: Among patients with diabetes, bempedoic acid reduces LDL cholesterol and high-sensitivity C-reactive protein and risk of cardiovascular events. Patients without diabetes had no increase in new-onset diabetes or worsening HbA1c with bempedoic acid. The efficacy and cardiometabolic safety profile of bempedoic acid makes it a clinical option for those with and without diabetes. FUNDING: Esperion Therapeutics.

Evolocumab effectiveness in the real-world setting: Austrian data from the pan-European observational HEYMANS study.

BACKGROUND: This real-world study examined clinical characteristics and dyslipidemia management among patients initiating evolocumab across 12 European countries. Austrian data are reported. METHODS: Data of consenting adults were collected for ≤ 6 months prior to evolocumab initiation (baseline) and ≤ 30 months post-initiation. Patient characteristics, lipid lowering therapy (LLT, i.e. statin and/or ezetimibe) and lipid values were collected from medical records. RESULTS: In Austria, 363 patients were enrolled. At baseline, 52% of patients initiated evolocumab without background LLT; the median (Q1, Q3) initial low-density lipoprotein cholesterol (LDL-C) level was 142 (111, 187) mg/dL. Within 3 months of evolocumab treatment, median LDL­C decreased by 59% to 58 (37, 91) mg/dL. This reduction was maintained over time, despite consistently infrequent use of background LLT. LDL-C < 55 mg/dL was attained by 65% of patients (76% with, 55% without background LLT). Evolocumab persistence was ≥ 90% at month 12 and month 30. CONCLUSION: In Austria, patients were initiated on evolocumab at LDL­C levels almost 3­times higher than the guideline-recommended clinical goal (< 55 mg/dL). Persistence with evolocumab was very high. Evolocumab led to a rapid and sustained LDL­C reduction with 65% attaining the LDL­C goal. Patients using evolocumab in combination with statins and/or ezetimibe were more likely to attain their LDL­C goal and thus decrease cardiovascular risk.

Overview of a collaborative global effort to address the burden of familial hypercholesterolaemia.

This is an overview of the EAS Familial Hypercholesterolaemia (FH) Studies Collaboration (FHSC) global consortium and registry (established 2015), which broadly addresses the global burden of FH. Eighty-seven National Lead Investigators from 74 countries form this expanding global consortium, and this global registry currently includes pooled data on 70,000 participants from participating countries to facilitate FH surveillance. Published first results from this global registry concluded that FH is diagnosed late, and management of LDL-cholesterol falls below guideline recommendations, and therefore earlier detection of FH and wider use of combination therapy is required. Further FHSC studies will follow on updated data including new countries, participants and variables, and non-DNA genetic information, and on the remaining cohorts in the registry. FHSC cross-sectional collaborative global studies are expected to promote FH detection earlier in life to subsequently initiate early lipid lowering therapy to reduce lifelong exposure to cumulative LDL-cholesterol thus reducing cardiovascular disease risk.

Safety and Tolerability of Inclisiran for Treatment of Hypercholesterolemia in 7 Clinical Trials.

BACKGROUND: Inclisiran is a small interfering RNA agent to lower low-density lipoprotein cholesterol. OBJECTIVES: The purpose of this study was to provide reliable evidence to date on the long-term safety profile of inclisiran. METHODS: This post hoc analysis comprised patients treated with 300 mg inclisiran sodium or placebo in the completed (ORION-1, -3, -5, -9, -10, and -11) and ongoing (ORION-8) trials. Exposure-adjusted incidence rates and Kaplan-Meier estimates of cumulative incidence of reported treatment-emergent adverse events (TEAE), abnormal laboratory measurements, and incidence of antidrug antibodies were analyzed. RESULTS: This analysis included 3,576 patients treated with inclisiran for up to 6 years and 1,968 patients treated with placebo for up to 1.5 years, with 9,982.1 and 2,647.7 patient-years of exposure, respectively. Baseline characteristics were balanced between groups. Kaplan-Meier analyses showed that TEAEs that were serious or led to discontinuation; hepatic, muscle, and kidney events; incident diabetes; and elevations of creatine kinase or creatinine accrued at a comparable rate between groups for up to 1.5 years, with similar trends continuing for inclisiran beyond this period. Numerically fewer major cardiovascular events reported as TEAEs occurred with inclisiran during this period. Treatment-induced antidrug antibodies were uncommon with inclisiran (4.6%), with few of these persistent (1.4%) and not associated with greater incidence of TEAEs leading to study drug discontinuation or serious TEAEs. CONCLUSIONS: Long-term treatment with inclisiran was well tolerated in a diverse population, without new safety signals, supporting the safety of inclisiran in patients with dyslipidemia.

Long-term treatment persistence and maintained reduction of LDL-cholesterol levels with evolocumab over 30 months: Results from the Spanish cohort of the European prospective HEYMANS study / Persistencia al tratamiento a largo plazo y reducción mantenida de los niveles de colesterol LDL con evolocumab durante 30 meses: resultados de la cohorte española del estudio prospectivo europeo HEYMANS

Aims: Limited data exist on low-density lipoprotein-cholesterol (LDL-C) level variability or long-term persistence with the monoclonal antibody evolocumab in routine clinical practice. HEYMANS (NCT02770131) is the first multi-country, multicenter, observational study of European patients initiating evolocumab as part of their routine clinical management, based on local reimbursement criteria (overall data recently published). The aim of this analysis is to describe clinical characteristics, baseline and changes in LDL-C levels, treatment patterns and persistence to evolocumab over 30 months in the Spanish cohort using data from the HEYMANS Registry. Methods: HEYMANS was a prospective study of adult patients (≥18 years) who received at least one dose of evolocumab. A total of 1951 patients were enrolled from 12 countries and were followed up for 30 months after evolocumab initiation. Data were collected for 6 months before evolocumab initiation and up to 30 months thereafter. The Spanish cohort included patients who started evolocumab in routine clinical practice from March 2016 to September 2019. Demographic and clinical characteristics, lipid-lowering therapies (LLT), and lipid levels were collected. (AU)
