Atherosclerosis is characterised by the accumulation of fatty deposits and plaque as a result of a continuously high level of low-density lipoprotein cholesterol (LDL-C) in the blood. The primary objective of this research is to assess the current status of knowledge, research endeavours and developmental trajectories about proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors in correlation with atherosclerosis treatment. Additionally, this study aims to compile bibliometric and scientometric investigations within this domain through rigorous scientometric analysis. Analysing the bibliometric landscape and global research trends associated with PCSK9 inhibitors can contribute valuable insights into comprehending atherosclerosis. This is exemplified by examining publications within the Web of Science Core Collection (WOSCC) database from 2008 to 2022. Citespace was used for frequency, co-occurrence, co-citation, grouping and burst analysis, and Microsoft Excel was used to manage descriptive datasets. Eight hundred eighty-five publications available from WOSCC database between the years 2008 and 2022 were extracted and examined. Over the period, 3,138 collaborating institutions from 87 countries, a staggering 7,750 writers involved and 325 distinct journals published about PCSK9 inhibitors studies. Among authors, Sabatine et al. and the journal The New England Journal of Medicine has had the most significant impact. Lipid-lowering therapy and bempedoic acid are the most prominent topical clusters associated with PCSK9 inhibitors, and the most often used keywords are efficacy, safety and PCSK9 inhibitors. We believe this is the first comprehensive analysis of PCSK9 inhibitors research and publications conducted using Scientometric. These results demonstrate the nascence of PCSK9 inhibitors research. They may encourage a wide range of stakeholders, particularly early career researchers from various disciplines, to work together in the future. [ABSTRACT FROM AUTHOR]

Novel lipid-lowering therapies are being introduced. Few studies exist of the real-world effectiveness of adenosine-tri-phosphate citrate lyase inhibition with bempedoic acid. This study audited bempedoic acid therapy in 216 consecutive patients from three hospital centres – a university hospital (n = 77) and two district general hospitals (n = 106 and 33). Cardiovascular disease (CVD) risk factors, prescription qualification criteria, efficacy and adverse effects were assessed. The population was aged 65.9 ± 11.0 years, 42% were male, 25% had type 2 diabetes, and 31% had familial hypercholesterolaemia. CVD was present in 19% and multibed vascular disease in 8%. Statin intolerance was reported in 92%. Bempedoic acid reduced total cholesterol by 1.58 ± 1.44 mmol/L (20%), LDL-C by 1.37 ± 1.31 mmol/L (27%), triglycerides by 0.22 mmol/L (2%) with an 0.06 mmol/L (1%) increase in HDL-C after 22 ± 9 months follow-up. An LDL-C <2.5 mmol/L was achieved in 40% and <2 mmol/L in 20%. Efficacy (r2 =.33) was predicted by baseline LDL-C (β =.54; p <.001). No significant changes were seen in transaminases, creatinine, creatine kinase, urate or HbA1c. Treatment was discontinued by 33% of patients and occurred due to myalgia (43%), lack of efficacy (16%) and gastrointestinal adverse effects (15%). No cases of gout were observed. In a logistic regression only the number of previous drug classes not tolerated (β = 1.60; p =.009) was a contributing factor to discontinuation. This audit suggests that bempedoic acid therapy is effective but that adverse effects and discontinuation are common. This suggests nocebo effects might be generalizable to all lipid-lowering drug therapies in susceptible individuals. [ABSTRACT FROM AUTHOR]

Achieving guideline-recommended low-density lipoprotein cholesterol (LDL-C) targets remains a significant challenge in clinical practice. This review assesses the barriers to reaching LDL-C goals and explores the potential solutions to these issues. When aiming for the recommended LDL-C goal, strategies like "lower is better" and "strike early and strong" should be used. The evidence supports the safety and efficacy of intensive lipid-lowering therapy post-acute coronary syndrome (ACS), leading to improved long-term cardiovascular health and atherosclerotic plaque stabilization. Despite the availability of effective lipid-lowering therapies, such as high-intensity statins, ezetimibe, the combination of both, bempedoic acid, and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, a substantial proportion of patients do not meet their LDL-C targets. Contributing factors include systemic healthcare barriers, healthcare provider inertia, patient non-adherence, and statin intolerance. Statin intolerance, often rather statin reluctance, is a notable obstacle due to perceived or expected side effects, which can lead to discontinuation of therapy. In conclusion, while there are obstacles to achieving optimal LDL-C levels post-ACS, these can be overcome with a combination of patient-centric approaches, clinical vigilance, and the judicious use of available therapies. The safety and necessity of reaching lower LDL-C goals to improve outcomes in patients post-ACS are well-supported by current evidence. [ABSTRACT FROM AUTHOR]

Cardiovascular diseases (CVDs) are a leading global cause of mortality and are primarily driven by atherosclerotic coronary artery disease. Their pathogenesis involves multi-factorial mechanisms, among which low-density lipoprotein (LDL) plays a causative role. Recent ESC/EAS guidelines advocate for a shift toward new risk estimation algorithms that better emphasize non-fatal cardiovascular events, lifetime risk prediction, and tailored pharmacological approaches, including statin + ezetimibe and triple therapy, in specific cases. Intensive lipid-lowering therapy has been shown to be pivotal, especially in post-acute coronary events. Intracoronary imaging has revealed insights into the composition of plaque and demonstrated the significant regression that can be achieved through the use of statins such as rosuvastatin and atorvastatin. The positive effects of Proprotein Convertase Subtilisin/Kexin type 9 (PCSK9) inhibitors, particularly alirocumab and evolocumab, on plaque regression, have been demonstrated. Inclisiran, which targets PCSK9 gene expression, significantly reduces LDL cholesterol. The associated challenges include hesitancy to prescribe intensive regimens and limited treatment adherence, highlighting the need for pharmacological combinations to improve therapeutic outcomes.

Atherosclerotic cardiovascular disease (ASCVD) represents a major global health challenge, significantly contributing to mortality rates. This chronic inflammatory condition affecting blood vessels is intricately linked to hypercholesterolemia, with elevated levels of low-density lipoprotein cholesterol (LDL-C) recognized as a central and modifiable risk factor. The effectiveness of lipid-lowering therapy (LLT) in mitigating ASCVD risk is well established, with studies revealing a substantial reduction in major ischemic events correlating with LDL-C reduction. While statins, often combined with ezetimibe, remain fundamental in dyslipidemia management, a significant proportion of patients on statin therapy continue to experience cardiovascular events. Recent pharmacological advancements, driven by a deeper understanding of atherogenesis, have unveiled novel therapeutic targets and potent drugs. Notably, agents like bempedoic acid and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors (evolocumab, alirocumab, inclisiran) have emerged as effective options to intensify LLT and achieve LDL-C goals, addressing limitations associated with statins, such as myopathy. Molecular insights into alternative pathways have spurred the investigation of emerging agents, offering promising perspectives for novel medications with efficacy comparable to established treatments, associated with advantages in cost and administration. This review provides a comprehensive overview of the evolving landscape of lipid-lowering strategies, highlighting the progress made in addressing ASCVD risk and the potential of upcoming therapies to further optimize cardiovascular prevention.

The modern history of cholesterol-lowering drugs started in 1972 when Dr. Akira Endo identified an active compound (compactin) that inhibited cholesterol biosynthesis from the culture broth of blue–green mold (Penicillium citrinum Pen-51). Since 1987, statins have represented the milestone for the treatment of atherosclerotic cardiovascular disease. A new therapy for the treatment of hypercholesterolemia since the discovery of statins is ezetimibe, the first and only agent inhibiting intestinal cholesterol absorption. Ezetimibe was approved by the FDA in October 2002. A year later, the association between gain-of-function PCSK9 genetic mutations and hypercholesterolemia was reported, and this discovery opened a new era in lipid-lowering therapies. Monoclonal antibodies and small-interfering RNA approaches to reduce PCSK9 were developed and approved for clinical use in 2015 and 2022, respectively. Finally, the newly approved bempedoic acid, an oral adenosine triphosphate citrate lyase inhibitor that lowers LDL-C, is able to reduce major adverse cardiovascular events in both primary and secondary prevention. In the present narrative review, we summarize the pharmacological properties and the clinical efficacy of all these agents currently used for a tailored therapy of hypercholesterolemia in patients with atherosclerotic cardiovascular disease.

Background: Low-density lipoproteins are now proven to be causal for atherosclerosis. Pharmacological treatment focuses on an increase of low-density lipoprotein (LDL) receptors, particularly in the hepatocyte, which leads to uptake of LDL from blood, thereby reducing the burden to the arterial wall. This mechanism has first been proven by statins to be effective to reduce cardiovascular morbidity and mortality. The concept of "the lower, the better" was shown by high-intensity statins and new compounds like ezetimibe, PCSK9 antibodies, inclisiran, and ultimately bempedoic acid. Summary: Although first considered only a relatively weak LDL-C lowering drug, bempedoic acid proved to be very effective, for example, in statin-intolerant patients to reduce cardiovascular events in the CLEAR-Outcomes study. In the era of personalized medicine, it should not be forgotten that the individual response to a LDL-C lowering drug can vary considerably. Bempedoic acid has a favorable safety profile, particularly it does not induce muscle problems because its precursor is not metabolized to the active drug in the muscle, and it does not induce hyperglycemia. Bempedoic acid probably is best used in combination with ezetimibe, which leads to LDL-C reductions in the range of moderately intensive statins; in an oral triple combination with a high-intensity statin, LDL-C reductions in the range of two-thirds can be achieved. Key Messages: Bempedoic acid is a further weapon against the atherogenic effect of LDL cholesterol – in both primary and secondary prevention. [ABSTRACT FROM AUTHOR]

The aim of the project is to develop a fast, simple, precise, and cost-efficient RP-HPLC method for measuring the amounts of Bempedoic Acid and Ezetimibe simultaneously in both pharmaceutical products and bulk samples. This technique has effectively achieved the separation of Bempedoic Acid and Ezetimibe in large quantities. The separation was performed using a Kromosil C18 150 x 4.6 mm, 5m analytical column at a wavelength of 280 nm. The mobile phase consisted of a mixture of Potassium dihydrogen orthophosphate, acetonitrile, and water in a ratio of 25:60:15. The pH of the buffer was adjusted to 6.0. The separation was carried out in isocratic elution mode with a flow rate of 1.2 ml/min. Bempedoic Acid had a retention time of 2.252 minutes, whereas Ezetimibe showed a retention duration of 2.987 minutes. Quantitative analysis of Bempedoic Acid and Ezetimibe was achieved using PDA detection at 280 nm using a linear calibration curve. The concentration ranges of 5-25 μg/ml (with a correlation coefficient of 0.9998) and 10-50 μg/ml (with a correlation coefficient of 0.9996) were used for reliable quantification. The limit of detection (LOD) for Bempedoic Acid was 0.1345 μg/ml, whereas the LOD for Ezetimibe was 0.2456 μg/ml. The proposed method is highly suitable for use in qualitycontrol laboratories for the bulk and pharmaceutical quantitative analysis of pharmaceuticals, whether used individually or in combination. This technique is characterised by its simplicity and efficiency, while yet ensuring a high level of accuracy and precision. [ABSTRACT FROM AUTHOR]

Cardiovascular diseases (CVDs) which consist of ischemic heart disease, stroke, heart failure, peripheral arterial disease, and several other cardiac and vascular conditions are one of the most common causes of death worldwide and often co-occur with diabetes mellitus and lipid disorders which worsens the prognosis and becomes a therapeutic challenge. Due to the increasing number of patients with CVDs, we need to search for new risk factors and pathophysiological changes to create new strategies for preventing, diagnosing, and treating not only CVDs but also comorbidities like diabetes mellitus and lipid disorders. As increasing amount of patients suffering from CVDs, there are many therapies which focus on new molecular targets like proprotein convertase subtilisin/kexin type 9 (PCSK9), angiopoietin-like protein 3, ATP-citrate lyase, or new technologies such as siRNA in treatment of dyslipidemia or sodium-glucose co-transporter-2 and glucagon-like peptide-1 in treatment of diabetes mellitus. Both SGLT-2 inhibitors and GLP-1 receptor agonists are used in the treatment of diabetes, however, they proved to have a beneficial effect in CVDs as well. Moreover, a significant amount of evidence has shown that exosomes seem to be associated with myocardial ischaemia and that exosome levels correlate with the severity of myocardial injury. In our work, we would like to focus on the above mechanisms. The knowledge of them allows for the appearance of new strategies of treatment among patients with CVDs. [ABSTRACT FROM AUTHOR]

The article titled "Impact of Bempedoic Acid on Cardiovascular Outcomes by Sex" discusses the results of the CLEAR Outcomes trial, which examined the effects of bempedoic acid on cardiovascular risk in patients who are unable or unwilling to take statins. The study found that bempedoic acid reduced cardiovascular risk and LDL cholesterol levels similarly in both females and males. The incidence of adverse events did not differ significantly between the two sexes. These findings suggest that bempedoic acid may be an important option for reducing cardiovascular risk in both men and women. [Extracted from the article]

Background and aims: Bempedoic Acid (BA) is a novel Lipid-Lowering Therapy (LLT). We performed a systematic review and meta-analysis to assess the efficacy and safety of BA in patients with hypercholesterolemia. Methods: PubMed, Scopus, and Cochrane library databases were searched for randomised controlled trials evaluating the efficacy and/or safety of BA compared with placebo. Trials investigating dosages other than 180 mg/die were excluded. Major adverse cardiovascular events (MACE) were the primary efficacy endpoint. LDL-cholesterol reduction was the primary laboratory endpoint. Pre-specified safety endpoints included muscle-related adverse events, new-onset diabetes, and gout. The protocol was registered on PROSPERO (temporary ID:399,867). Results: Study search identified 275 deduplicated results. 11 studies, encompassing 18,315 patients (9854 on BA vs 8461 on placebo/no treatment) were included. BA was associated with a reduced risk of MACE (OR 0.86, 95% CI 0.79–0.95), myocardial infarction (OR 0.76, 95% CI 0.64–0.88) and unstable angina (OR 0.69, 95% CI 0.54–0.88) compared to control, over a median follow up of 87 (15–162) weeks. BA was associated with a reduction of LDL-Cholesterol (mean difference [MD]–22.42,95% CI − 24.02% to − 20.82%), total cholesterol (− 16.50%,95% − 19.21% to − 13.79%), Apo-B lipoprotein (− 19.55%, − 22.68% to − 16.42%) and high-sensitivity CRP (− 27.83%, − 31.71% to − 23.96%) at 12 weeks. BA was associated with a higher risk of gout (OR 1.55, 95% CI 1.27–1.90) as compared with placebo. Efficacy on laboratory endpoints was confirmed, with a variable extent, across patients on statin or ezetimibe background therapy. Conclusions: The improved cholesterol control achieved with BA translates into a reduced risk of MACE, including myocardial infarction and coronary revascularisation. The drug has a satisfactory safety profile except for an increased risk of gout. [ABSTRACT FROM AUTHOR]

Aim: This systematic review and meta-analysis was conducted to synthesize the efficacy and safety of bempedoic acid in patients requiring lipid-lowering therapy. Methods: PubMed, Embase, and Scopus databases were searched for randomized controlled trials from inception till June 2023. The primary outcome was major adverse cardiovascular events (MACE), and secondary outcomes were all-cause mortality, serum lipid profile, and adverse events between bempedoic acid and comparators. ROB2 was used for risk of bias assessment. We pooled mean differences or relative risks (RR) along with 95% confidence intervals (random-effects model). Results: Five-hundred and thirty-one studies were screened and 17 (n = 21,131) were included for review. There was a significant reduction in the risk of MACE [RR, 0.88 (95% CI: 0.77 to 0.99), p = 0.03)] and all-cause mortality [RR, 0.90 (95% CI: 0.82 to 0.98), p = 0.02] following bempedoic acid treatment. Treatment with bempedoic acid led to a significant reduction in the mean serum total cholesterol [− 34.41 mg/dl (95% CI: − 42.43 to − 26.39), p < 0.001], low-density lipoprotein cholesterol (LDL-C) [− 33.91 mg/dl (95% CI: − 39.66 to − 28.17), p < 0.001], as well as high-density lipoprotein cholesterol (HDL-C) [− 2.40 mg/dl (95% CI: − 3.09 to − 1.71), p < 0.001] levels. However, there was a significant increase in the risk of hyperuricemia [RR, 2.05 (95% CI: 1.81 to 2.33), p < 0.001] following bempedoic acid treatment. The number needed to harm was large for all safety outcomes. The GRADE of evidence was moderate for all outcomes. Conclusion: Bempedoic acid reduces the risk of MACE and all-cause mortality, lowers serum total cholesterol and LDL-C levels, and has a favorable safety profile.

Bempedoic acid is an adenosine triphosphate citrate lyase inhibitor that lowers low‐density lipoprotein cholesterol by inhibiting cholesterol synthesis and upregulating hepatic low‐density lipoprotein receptor expression. After oral dosing, bempedoic acid was readily absorbed, attaining maximum concentrations with a median time of 3.5 hours, and may be taken without regard to food. Steady‐state oral pharmacokinetics in healthy adults receiving bempedoic acid at the approved 180 mg/day dose were characterized by mean maximum concentration of 20.6 µg/mL, area under the concentration–time curve over 24 hours of 289 µg·h/mL, and elimination half‐life of 21.1 hours. Multiple‐dose pharmacokinetics were linear at bempedoic acid doses of 120–220 mg/day. Circulating concentrations of the active metabolite ESP15228 were 18.0% of bempedoic acid concentrations on average. Comparisons of bempedoic acid 180 mg/day pharmacokinetics after single and multiple dosing revealed no clinically meaningful differences between Japanese, Chinese, and Western subjects. Mean estimates of bempedoic acid elimination half‐life in Japanese (25.2 hours) and Chinese (20.0 hours) subjects were comparable to Western subjects (23.9 hours) following 14 days of once‐daily dosing. Bempedoic acid was generally safe and well tolerated up to a dose of 220 mg/day across the study populations described herein. [ABSTRACT FROM AUTHOR]

Bempedoic acid is an orally administered prodrug that, like statins, reduces cholesterol biosynthesis (by inhibiting ATP citrate lyase, a key enzyme in cholesterol synthesis prior to 3-hydroxy-3-methyl-glutaryl CoA reductase). Its lipid efficacy has been evaluated in several clinical trials, achieving a 17-28% reduction in LDL-c levels, and showing an anti-inflammatory effect. Unlike statins, their use is not associated with myotoxic effects. Recently, the cardiovascular benefit of bempedoic acid in patients intolerant to statins has been confirmed in the CLEAR OUTCOMES clinical trial. The use of bempedoic acid has been approved as an adjunct to diet and statins, alone or in combination with ezetimibe, in patients with hypercholesterolemia, mixed dyslipidemia, or statin intolerance. New recommendations also suggest their use as alternative drugs in individuals at high cardiovascular risk or with very high LDL-c levels who do not reach lipid targets with other lipid-lowering drugs. Likewise, it could be considered as a second- or third-line therapy in patients intolerant to statins. [ABSTRACT FROM AUTHOR]

Reducing low-density lipoprotein cholesterol (LDL-C) levels is crucial to the prevention of atherosclerotic cardiovascular disease (ASCVD). However, many patients, especially those at very high ASCVD risk or with familial hypercholesterolemia (FH), do not achieve target LDL-C levels with statin monotherapy. The underutilization of novel lipid-lowering therapies (LLT) globally may be due to cost concerns or therapeutic inertia. Emerging approaches have the potential to lower LDL-C and reduce ASCVD risk further, in addition to offering alternatives for statin-intolerant patients. Shifting the treatment paradigm towards initial combination therapy and utilizing novel LLT strategies can complement existing treatments. This review discusses innovative approaches including combination therapies involving statins and agents like ezetimibe, bempedoic acid, cholesterol ester transfer protein (CETP) inhibitors as well as strategies targeting proprotein convertase subtilisin/kexin type 9 (PCSK9) and angiopoietin-like protein 3 (ANGPTL3) inhibition. Advances in nucleic acid-based therapies and gene editing are innovative approaches that will improve patient compliance and adherence. These strategies demonstrate significant LDL-C reductions and improved cardiovascular outcomes, offering potential for optimal LDL-C control and reduced ASCVD risk. By addressing the limitations of statin monotherapy, these approaches provide new management options for elevated LDL-C levels. [ABSTRACT FROM AUTHOR]

The management of low-density lipoprotein cholesterol (LDL-C) levels is a central strategy for the prevention of atherosclerotic cardiovascular disease. Current United States (2018 American Heart Association/American College of Cardiology/Multisociety) and European (2019 European Society of Cardiology/European Atherosclerosis Society) guidelines endorse statin therapy as the first-line therapy for pharmacologic LDL-C lowering. However, in clinical practice up to 30% of patients report partial or complete intolerance to statin therapy. While the nocebo effect with statins is well described, perceived statin intolerance prevents many patients from achieving LDL-C thresholds associated with clinical benefit. Bempedoic acid is a novel, oral, non-statin lipid-lowering therapy that works by inhibiting adenosine triphosphate-citrate lyase, an enzymatic reaction upstream of 3-hydroxy-3-methylglutaryl coenzyme A reductase in the hepatic cholesterol synthesis pathway. Bempedoic acid confers reduction in LDL-C of ~18% on background statin therapy, ~21% in patients with statin intolerance, and ~38% when given in fixed-dose combination with ezetimibe. The CLEAR Outcomes trial, which enrolled high-risk primary and secondary prevention patients with reported statin intolerance and LDL-C levels ≥100 mg/dL, showed that bempedoic acid compared with placebo reduced 4-component major adverse cardiovascular events (MACE) by 13% (hazard ratio 0.87, 95% confidence interval 0.79-0.96). Bempedoic acid also reduced 3-component MACE by 15%, myocardial infarction by 23% and coronary revascularization by 19%. The benefit was even greater in the primary prevention cohort (hazard ratio 0.70, 95% confidence interval 0.55-0.89) for 4-component MACE. Bempedoic acid was associated with increases in uric acid levels and cholelithiasis, but numerically fewer events of myalgia and new-onset diabetes. These findings confirm that bempedoic acid is an effective approach to reduce cardiovascular outcomes in high-risk patients with statin intolerance who require further reduction in LDL-C.

We aimed to understand the impact of physicians' perception about LDL-cholesterol (LDLc) control on the management of patients with dyslipidemia in Spain. We performed a cross-sectional and multicenter study, in which 435 healthcare professionals participated in face-to-face meetings, collecting qualitative and quantitative information related to hypercholesterolemia management. Additionally, aggregated anonymized data of the last 10 patients with hypercholesterolemia attended by each physician were collected. A total of 4,010 patients (8%, 13%, 16% and 61% with low, moderate, high, and very high cardiovascular [CV] risk) were included. Physicians' perception was that 62% of their patients attained LDLc goals (66%, 63%, 61% and 56%, for low, moderate, high and very high CV risk, respectively). However, when looking into the data only 31% (vs 62% p< 0.01) of patients attained the LDLc goals (47%, 36%, 22% and 25%, respectively). Overall, 33% of patients were taking high intensity statins, 32% statin/ezetimibe, 21% low/moderate intensity statins and 4% PCSK9 inhibitors. These numbers were 38%, 45%, 8% and 6% for very high risk patients and 44%, 21%, 21% and 4% for high CV risk patients. In 32% of patients, a change in lipid lowering therapy was performed after the visit, mainly combining statins/ezetimibe (55%). In Spain, most patients with dyslipidemia do not achieve the recommended LDLc goals because of an insufficient intensification of lipid lowering therapy. On the one hand, this is in part due to physicians misperception on preventive LDLc control and the need for repeated advice to patient, and, on the other, to the lack of patient adherence. [Display omitted] • In Spain, most patients do not achieve recommended LDLc goals. • This is mainly due to an insufficient intensification of LLT. • The misperception of physicians about the real LDLc control and underestimation of CV risk could explain this poor control. • Intensification of LLT is desirable to attain LDLc targets.

The relative risk reduction of cardiovascular events is proportional to the absolute reduction in LDL-C levels, the primary target of therapy, no matter the way of reduction. During the last decades, the therapeutic regimens for reducing the LDL-C levels have been immerged and improved, with favorable effects on the atherosclerotic process and clinical benefits of various cardiovascular outcomes. From a practical view of point, this review is focusing only on the current available lipid lowering agents: statins, ezetimibe, anti PCSK9 monoclonal antibodies, the small interfering RNA (siRNA) agent, Inclisiran, and Bempedoic acid. The recent changes in lipid lowering regimens, including the early combination of lipid lowering agents and "Low LDL-C" levels <30 mg/dL for high/very high cardiovascular risk patients will also be discussed.

The bioequivalence of bempedoic acid oral suspension and commercial immediate release (IR) tablet formulations were assessed using a physiologically based pharmacokinetic (PBPK) model. The mechanistic model, developed from clinical mass balance results and in vitro intrinsic solubility, permeability, and dissolution data, was verified against observed clinical pharmacokinetics (PK) results. Model inputs included a fraction of a dose in solution (0.01%), viscosity (118.8 cps), and median particle diameter (50 µm) for the suspension and particle diameter (36.4 µm) for IR tablets. Dissolution was determined in the relevant media (pH 1.2–6.8) in vitro. Model simulations of bioequivalence predicted oral suspension (test) to IR tablet (reference) geometric mean ratio estimates of 96.9% (90% confidence interval [CI]: 92.6–101) for maximum concentration and 98.2% (90% CI: 87.3–111) for the area under the concentration–time curve. Sensitivity analyses showed gastric transit time had a minor impact on model predictions. Oral suspension biopharmaceutical safe space was defined by extremes of particle size and the percent of bempedoic acid in solution. PBPK model simulations predicted that the rate and extent of bempedoic acid absorption are unlikely to exhibit clinically meaningful differences when dosed as an oral suspension compared with an IR tablet without requiring a clinical bioequivalence study in adults.

Primarily a consequence of sedentary lifestyle, atherosclerosis has already reached pandemic proportions, and with every year the burden of it is only increasing. As low-density lipoprotein cholesterol (LDL-C) represents a crucial factor in atherosclerosis formation and progression, stringent lipid-lowering therapy could conceivably be the key to preventing the unfavorable outcomes that arise as a consequence of atherosclerosis. The use of statins in lipid-lowering is often burdened by adverse events or is insufficient to prevent cardiovascular events as a monotherapy. Therefore, in the present review, the authors aimed to discuss the underlying mechanisms of dyslipidemia and associated atherosclerotic cardiovascular disease (ASCVD) and preclinical and clinical trials of novel therapeutic approaches to its treatment, some of which are still in the early stages of development. Apart from novel therapies, a novel change in perspective is needed. Specifically, the critical objective in the future management of ASCVD is to embrace emerging evidence in the field of atherosclerosis, because clinicians are often burden by common practice and personal experience, both of which have so far been shown to be futile in the setting of atherosclerosis.

Lipid-lowering drugs have been shown to have cardioprotective effects but may have hidden cardiotoxic properties. Therefore, here we aimed to investigate if chronic treatment with the novel lipid-lowering drug bempedoic acid (BA) exerts hidden cardiotoxic and/or cardioprotective effects in a rat model of acute myocardial infarction (AMI). Wistar rats were orally treated with BA or its vehicle for 28 days, anesthetized and randomized to three different groups (vehicle + ischemia/reperfusion (I/R), BA + I/R, and positive control vehicle + ischemic preconditioning (IPC)) and subjected to cardiac 30 min ischemia and 120 min reperfusion. IPC was performed by 3 × 5 min I/R cycles before ischemia. Myocardial function, area at risk, infarct size and arrhythmias were analyzed. Chronic BA pretreatment did not influence cardiac function or infarct size as compared to the vehicle group, while the positive control IPC significantly reduced the infarct size. The incidence of reperfusion-induced arrhythmias was significantly reduced by BA and IPC. This is the first demonstration that BA treatment does not show cardioprotective effect although moderately reduces the incidence of reperfusion-induced arrhythmias. Furthermore, BA does not show hidden cardiotoxic effect in rats with AMI, showing its safety in the ischemic/reperfused heart. [ABSTRACT FROM AUTHOR]

The validation of the developed method is done as per ICH guidelines. The method was developed on Waters HPLC using a Kromasil 100-5-C18 (4.6 × 250 mm) column with a detection wavelength of 220 nm. The mobile phase consists of 0.1 % OPA in water: Acetonitrile (50:50 v/v). The retention time for Rosuvastatin calcium and Bempedoic acid was found as 5.4 and 10.7 min respectively. The linearity range was established between 10.0–100.0 µg/ml for Rosuvastatin calcium and 45.0–450.0 µg/ml for Bempedoic acid. The correlation coefficients (r2 values) for Rosuvastatin calcium and Bempedoic Acid were 0.9985 and 0.9988 respectively, indicating a strong concentration–response relationship. The method was found to be specific as there was no interference with the peak of Rosuvastatin calcium and Bempedoic acid in presence of excipients. The % Recovery of the method was found to be 98.64 %, 99.35 %, and 98.27 % for Rosuvastatin calcium and 99.11 %, 99.16 %, and 99.46 % for Bempedoic Acid. Therefore, the method has good trueness. Repeatability analysis of 6 samples revealed %RSD values of 0.92 % and 1.41 % for Rosuvastatin calcium and Bempedoic Acid respectively. The method is precise as the mean %RSD for Intraday studies of Rosuvastatin calcium and Bempedoic acid was 0.6064 % and 0.5289 % respectively while the Interday studies were 0.8763 % and 0.4955 % respectively. The LOD and LOQ for Rosuvastatin calcium are 0.054 µg/ml and 0.163 µg/ml and for Bempedoic acid are 0.127 µg/ml and 0.387 µg/ml respectively. Also, the method is robust as there was no significant change in result upon changing the method parameter. The developed method is environment friendly and is suitable for the quality control analysis of Rosuvastatin calcium and Bempedoic acid either alone or in combination. [ABSTRACT FROM AUTHOR]

Bempedoic acid exhibits promising potential in hyperlipidemia therapy and preventing cardiovascular events. However, investigations into its adverse drug reactions remain scant. This study seeks to utilize data mining techniques with the FDA Adverse Event Reporting System (FAERS) database to assess adverse drug events (ADEs) linked to bempedoic acid. Based on the drug's market release timeline, we extracted data from the FAERS database covering the fourth quarter of 2020 through the fourth quarter of 2023 for disproportionality analysis. This study gathered a total of 5,797,543 adverse event case reports, of which 735 were linked to bempedoic acid. These reports covered 19 System Organ Classes (SOCs) and 22 Preferred Terms (PTs). Predominantly, the musculoskeletal and nervous systems were implicated in these adverse events. By conducting PT-level screening, various signals for ADEs were detected, including myalgia (ROR 30.33, PRR 28.51, IC 4.83, EBGM 28.47), arthralgia (n = 34, ROR 6.34, PRR 6.09, IC 2.61, EBGM 6.09), tendon disorders (ROR 99.57, PRR 98.75, IC 6.62, EBGM 98.28), and dizziness (ROR 3.18, PRR 3.13, IC 1.65, EBGM 3.13). Particularly noteworthy was the hypertensive crisis (ROR 28.63, PRR 28.51, IC 4.83, EBGM 28.47), which exhibited a robust signal strength, an observation previously unreported in clinical studies and drug labeling. While our results are largely consistent with the drug's specifications, several new adverse reaction signals, such as hypertensive crisis, have not been previously documented. Therefore, further investigations are necessary to assess these unlabeled adverse reactions, offering crucial support for the clinical utilization of bempedoic acid. • Females reported more ADEs. • Strongest signals: musculoskeletal, nervous, GI disorders. • Myalgia, arthralgia most frequent.

Low-density lipoprotein cholesterol (LDL-C) plays a crucial role in the development of atherosclerosis. Statin therapy is the standard treatment for lowering LDL-C in primary and secondary prevention. However, some patients do not reach optimal LDL-C target levels or do not tolerate statins, especially when taking high doses long-term. Combining statins with different therapeutic approaches and testing other new drugs is the future key to reducing the burden of cardiovascular disease (CVD). Recently, several new cholesterol-lowering drugs have been developed and approved; others are promising results, enriching the pharmacological armamentarium beyond statins. Triglycerides also play an important role in the development of CVD; new therapeutic approaches are also very promising for their treatment. Familial hypercholesterolemia (FH) can lead to CVD early in life. These patients respond poorly to conventional therapies. Recently, however, new and promising pharmacological strategies have become available. This narrative review provides an overview of the new drugs for the treatment of dyslipidemia, their current status, ongoing clinical or preclinical trials, and their prospects. We also discuss the new alternative therapies for the treatment of dyslipidemia and their relevance to practice. [ABSTRACT FROM AUTHOR]

Dyslipidaemia is a well-known risk factor for the development of cardiovascular disease, a leading cause of morbidity and mortality in developed countries. As a consequence, the medical community has been dealing with this problem for decades, and traditional statin therapy remains the cornerstone therapeutic approach. However, clinical trials have observed remarkable results for a few agents effective in the treatment of elevated serum lipid levels. Ezetimibe showed good but limited results when used in combination with statins. Bempedoic acid has been thoroughly studied in multiple clinical trials, with a reduction in LDL cholesterol by approximately 15%. The first approved monoclonal antibodies for the treatment of dyslipidaemia, PCSK9 inhibitors, are currently used as second-line treatment for patients with unregulated lipid levels on statin or statin combination therapy. A new siRNA molecule, inclisiran, demonstrates great potential, particularly concerning compliance, as it is administered twice yearly and pelacarsen, an antisense oligonucleotide that targets lipoprotein(a) and lowers its levels. Volanesorsen is the first drug that was designed to target chylomicrons and lower triglyceride levels, and olezarsen, the next in-line chylomicron lowering agent, is currently being researched. The newest possibilities for the treatment of dyslipidaemia are ANGPTL3 inhibitors with evinacumab, already approved by the FDA, and EMA for the treatment of familial hypercholesterolemia. This article provides a short summary of new agents currently used or being developed for lipid lowering treatment. [ABSTRACT FROM AUTHOR]

The effects of bempedoic acid on mortality in the secondary prevention setting have not been examined. We used data from the overall and primary prevention reports of CLEAR – Outcomes to reconstruct data for the secondary prevention population. A Bayesian analyses was employed to calculate the posterior probability of benefit or harm for the outcomes of all-cause mortality, cardiovascular mortality, and major adverse cardiovascular events (MACE). Relative effect sizes are presented as risk ratios (RR) with 95% credible intervals (CrI), which represent the intervals that true effect sizes are expected to fall in with 95% probability, given the priors and model. In primary prevention, the posterior probability of bempedoic acid decreasing all-cause and cardiovascular mortality was 99.4% (RR: 0.70; 95% CrI: 0.51 to 0.92) and 99.7% (RR: 0.58; 95% CrI: 0.38 to 0.86) respectively. In secondary prevention, the posterior probability of bempedoic acid increasing all-cause and cardiovascular mortality was 96.6% (RR: 1.15; 95% CrI: 0.99 to 1.33) and 97.2% (RR: 1.21; 95% CrI: 1.00 to 1.45) respectively. The probability of bemepdoic acid reducing MACE in the primary and secondary prevention settings was 99.9% (RR: 0.70; 95% CrI: 0.54 to 0.88) and 95.8% (RR: 0.92; 95% CrI: 0.84 to 1.01) respectively. In contrast to its effect in the primary prevention subgroup of CLEAR – Outcomes, bempedoic acid resulted in a more modest MACE reduction and a potential increase in mortality in the secondary prevention subgroup. Whether these findings represent true treatment effect heterogeneity or the play of chance requires further evidence. [Display omitted] • Bempedoic acid had less favorable effects in secondary versus primary prevention. • The effect on major adverse cardiovascular events (MACE) was more modest in secondary prevention. • There was a potential increase in all-cause and cardiovascular mortality in secondary prevention. • The probability of increasing mortality was equal to that of reducing MACE in secondary prevention. • Further data is needed to verify if true treatment effect heterogeneity exists.

ATP-citrate lyase (Acly) is the target of the new class low-density lipoprotein-cholesterol (LDL-C)-lowering drug bempedoic acid (BA). Acly is a key metabolic enzyme synthesizing acetyl-CoA as the building block of cholesterol and fatty acids. Treatment with BA lowers circulating lipid levels and reduces systemic inflammation, suggesting a dual benefit of this drug for atherosclerosis therapy. Recent studies have shown that targeting Acly in macrophages can attenuate inflammatory responses and decrease atherosclerotic plaque vulnerability. Therefore, it could be beneficial to extend the application of Acly inhibition from solely lipid-lowering by liver-specific inhibition to also targeting macrophages in atherosclerosis. Here, we outline the possibilities of targeting Acly and describe the future needs to translate these findings to the clinic. Bempedoic acid targets ATP-citrate lyase (Acly) in the liver, thereby lowering low-density lipoprotein-cholesterol (LDL-C) and systemic inflammation. Acly is a metabolic enzyme at the crossroads between carbohydrate metabolism, lipid metabolism, and histone acetylation. Targeting Acly in macrophages yields additive therapeutic value to broaden the strategy from solely lipid-lowering to targeting inflammatory activation. [ABSTRACT FROM AUTHOR]

Bempedoic acid is a small-molecule inhibitor of adenosine triphosphate-citrate lyase (ACL) that is effective in the treatment of hypercholesterolemia and hypertension. In this paper, a new, six-step synthesis of bempedoic acid with 42% overall yield is reported. Ketone formation by electrochemical decarboxylation of dialkylated malonic acid is introduced as the key step of this process. This method uses mild conditions and its high efficiency makes it potentially suitable for industrial production. [ABSTRACT FROM AUTHOR]

Diabetes is a major risk factor for atherosclerotic cardiovascular disease (ASCVD) in which dyslipidaemia plays a crucial role. Statins are first line therapy for primary and secondary prevention of ASCVD; however, adverse events include reversible musculoskeletal and liver side effects in addition to a diabetogenic association. In this short review, we provide a succinct narrative of the future role and current trial data of a novel first-in-class molecule, bempedoic acid. The authors provide their expert insight with a focus on Phase III randomised controlled trials (RCT) of bempedoic acid. Bempedoic acid was approved by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) in February and March 2020, respectively, and is a novel molecule which inhibits cholesterol biosynthesis in the same mechanistic pathway as statins. It is a first-in-class small molecule, delivered as a prodrug and administered as an oral, once-daily dose that decreases low-density lipoprotein cholesterol (LDL-C) levels. Phase II and III RCTs have demonstrated efficacy with adequate safety data as mono- or combination therapy with statins and ezetimibe. Bempedoic acid is hepatically converted to the active drug with a lack of activation in skeletal muscle. Due to this novel mechanism, musculoskeletal-related adverse events exhibit a lower prevalence providing an alternative pharmacotherapy in statin-intolerant patients. Bempedoic acid may be used as an adjunct to diet and maximally tolerated statin therapy or in statin-intolerant patients for the treatment of dyslipidaemia. The recent National Institute of Health and Care Excellence (NICE) (UK) technology appraisal guidance [TA694] published in April 2021 recommended bempedoic acid with ezetimibe as a treatment option for primary hypercholesterolaemia or mixed dyslipidaemia if statins are not tolerated or contraindicated and if there is inadequate control of LDL-C with ezetimibe alone. Additionally, outcomes trials evaluating 'hard' endpoints in statin-intolerant patients or those with ASCVD are currently underway. [ABSTRACT FROM AUTHOR]

Adding to the foundation of statins, ezetimibe and proprotein convertase subtilisin-kexin type 9 inhibitors (PCSK9i), novel, emerging low-density lipoprotein cholesterol (LDL-C)-lowering therapies are under development for the prevention of cardiovascular disease. Inclisiran, a small interfering RNA molecule that inhibits PCSK9, only needs to be dosed twice a year and has the potential to help overcome current barriers to persistence and adherence to lipid-lowering therapies. Bempedoic acid, which lowers LDL-C upstream from statins, provides a novel alternative for patients with statin intolerance. Angiopoetin-like 3 protein (ANGPTL3) inhibitors have been shown to provide potent LDL-C lowering in patients with homozygous familial hypercholesterolemia without major adverse effects as seen with lomitapide and mipomersen, and may reduce the need for apheresis. Finally, CETP inhibitors may yet be effective with the development of obicetrapib. These novel agents provide the clinician the tools to effectively lower LDL-C across the entire range of LDL-C-induced elevation of cardiovascular risk, from primary prevention and secondary prevention to null-null homozygous familial hypercholesterolemia patients.

Many patients with hypercholesterolemia fail to achieve sufficient low-density lipoprotein cholesterol (LDL-C) lowering despite use of guideline-recommended lipid-lowering therapies. This study evaluated LDL-C lowering with the combination of bempedoic acid, ezetimibe, and atorvastatin. This was a phase 2, randomized, double-blind, placebo-controlled study (NCT03051100). After washout of lipid-lowering drugs, patients were randomized 2:1 to triple therapy (bempedoic acid 180 mg, ezetimibe 10 mg, and atorvastatin 20 mg; n = 43) or placebo (n = 20) once daily for 6 weeks. The primary endpoint was percent change from baseline in LDL-C at week 6. Mean age for the 63 randomized patients was 61.2 years; baseline LDL-C was 154.8 mg/dL. At week 6, mean LDL-C lowering with triple therapy (−63.6%) was significantly greater than with placebo [–3.1%; difference, −60.5% [(95% CI, −68.0% to −53.0%); p < 0.001]. Significant reductions with triple therapy vs. placebo were also observed for non–high-density lipoprotein cholesterol, total cholesterol, apolipoprotein B, and high-sensitivity C-reactive protein (p < 0.001 for all). With triple-therapy, 90% of patients achieved LDL-C <70 mg/dL and 95% of patients had ≥50% lower LDL-C from baseline to week 6; no patients in the placebo group met either goal. The majority of treatment-emergent adverse events were mild to moderate in severity. No patients experienced clinically relevant elevations in aminotransferase or creatine kinase levels. Among patients with hypercholesterolemia, the combination of bempedoic acid, ezetimibe, and atorvastatin significantly lowered LDL-C, allowing more than 90% of patients in this study to reach guideline-recommended LDL-C goals. Image 1 • Many patients require combination therapy to achieve low-density lipoprotein cholesterol (LDL-C) goals. • Phase 2 study evaluating bempedoic acid, ezetimibe, and atorvastatin triple therapy. • Triple therapy significantly lowered LDL-C levels by 60.5% vs placebo. • More than 90% of patients achieved LDL-C <70 mg/dL with triple therapy. • Triple therapy was generally well-tolerated.

Atherosclerotic cardiovascular diseases (ASCVD) are still the leading cause of morbidity and mortality in most developed countries and even more in developing countries. Dyslipidemia is a well known main risk factor for ASCVD. Lipid-lowering treatment, particularly lowering LDL-cholesterol (LDL-C), can decrease the risk for ASCVD. New data and guidelines based upon them suggest that we should go with LDL-C levels as low as we can. Therefore, conventional lipid lowering agents (statins and statins+ezetimibe) are not enough mainly because of poor compliance and statin intolerance which is in the real world mostly pseudo-intolerance. PCSK9 inhibitors provided a new hope to further decrease LDL-C but are still expensive, they have to be injected subcutaneously twice a month and their long-lasting adverse effects are not known. Therefore, there is a constant need to develop novel, more potent, more safe, less expensive, more user friendly regimens of hypolipemic agents (bempedoic acid, selective PPAR alpha receptor modulators etc). One of the ways to overcome poor compliance and increase the potency of therapy with less adverse effects are fixed combinations of established drugs (statin+ezetimibe). The future of hypolipemic agents is based on antisense therapy, ie. the use of specific oligonucleotide sequences blocking the translation of the selected protein (targeting apolipoprotein CIII, lipoprotein (a), apolipoprotein B) or RNA silencing technique (PCSK9 mRNA) and are in various stages of clinical trials. Some of them are almost ready to use in everyday clinical practice. High risk and very high risk patients (eg. familial hypercholesterolemia, familial severe chylomicronemia syndrome) will benefit most. The aim of this review is to inform about novel hypolipemic agents – potent and safe drugs for dyslipidemia which should reduce the risk of ASCVD. [ABSTRACT FROM AUTHOR]

Purpose An update on clinical development of a first-in-class oral medication for adjunctive cholesterol lowering in high-risk patients with persistent elevation of low-density lipoprotein cholesterol (LDL-C) despite statin therapy is reviewed. Summary Despite the proven efficacy of statin therapy, many patients cannot reach LDL-C goals with statins alone, largely due to inadequate response or intolerance. Nonstatin treatment options to reduce LDL-C include ezetimibe, bile acid sequestrants, and proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitors; however their use has been limited by modest clinical benefit or high treatment costs. Novel nonstatin treatments are in development to further address the needs of this population. Bempedoic acid is a first-in-class oral adenosine triphosphate (ATP) citrate lyase inhibitor being evaluated as an additional treatment option for high-risk patients requiring further reduction in LDL-C. Bempedoic acid has been evaluated in multiple phase 2 and phase 3 trials as monotherapy or for use in combination with ezetimibe and/or statin therapy. Treatment with bempedoic acid has been demonstrated to result in significant reductions in LDL-C and several other cardiovascular risk markers without the myalgia associated with statin therapy. Conclusion Bempedoic acid, used alone or with ezetimibe in a fixed-dose combination formulation, may be an effective alternative to current guideline-recommended nonstatin therapies in patients who do not attain adequate LDL-C lowering with maximally tolerated statin therapy and in statin-intolerant patients at risk for atherosclerotic cardiovascular disease.

Although numerous trials have convincingly shown benefits of statin therapy in both primary and secondary prevention of atherosclerotic cardiovascular disease (ASCVD), most showed relative risk reductions of 25–40%, and thus many individuals continue to have ASCVD events despite statin therapy. Substantial progress has been made in developing therapies that address the residual risk for ASCVD despite statin therapy. In this review, we summarize progress of currently available therapies along with therapies under development that further reduce low-density lipoprotein cholesterol and apolipoprotein B–containing lipoproteins, reduce lipoprotein(a), reduce ASCVD events in patients with high triglycerides, and directly target inflammation to reduce ASCVD risk.

Background: Bempedoic acid is an oral, once-daily, first-in-class drug being developed for the treatment of hyperlipidemia. However, evidence of bempedoic acid use for the prevention of cardiovascular events and diabetes is lacking. Thus, we aim to evaluate the benefit and safety of bempedoic acid use for the prevention of cardiovascular events and diabetes. Methods: We searched Medline, Embase, and the Cochrane Central Register of Controlled Trials with no language restriction from inception until March 3, 2020. Pairs of reviewers independently identified randomized controlled trials comparing the use of bempedoic acid with placebo or no treatment for primary prevention of cardiovascular events in statin-intolerant patients with hypercholesterolemia. The primary outcomes were major adverse cardiac events, and percent change in LDL-C. Results: We identified 11 trials including a total of 4391 participants. Bempedoic acid use was associated with a reduction in composite cardiovascular outcome (RR 0.75, 95% CI 0.56–0.99; I2 = 0%). Bempedoic acid reduced LDL-C levels (MD − 22.91, 95% CI − 27.35 to − 18.47; I2 = 99%), and similarly reduced CRP levels (MD -24.70, 95% CI − 32.10 to − 17.30; I2 = 53%). Bempedoic acid was associated with a reduction in rates of new-onset or worsening diabetes (RR 0.65, 95% CI 0.44–0.96; I2 = 23%). Conclusions: Bempedoic acid in patients with hypercholesterolemia was associated with a lower risk of cardiovascular events and diabetes. [ABSTRACT FROM AUTHOR]

Similarly in the case of statin intolerance, it may be preferable to start treatment immediately with available non-statin agents, rather than waiting months until the maximally tolerated dose of statin can be titrated, increasing the risk of LDL-C visit-to-visit variability and increased CVD event risk [5]. Keywords: Bempedoic acid; Combination therapy; Lipid-lowering therapy; Statins EN Bempedoic acid Combination therapy Lipid-lowering therapy Statins 86 88 3 03/03/21 20210301 NES 210301 Exposure to low-density lipoprotein cholesterol (LDL-C) causes atherosclerotic cardiovascular disease (ASCVD) [1], and the importance of the mantra "lower is better for longer"[2],[3] cannot be understated. However, muscle symptoms are often misattributed to statins [11] and with careful management, including switching between statins and dose reduction, applying alternate-day statin therapy or combination therapy [12], approximately 95% of seemingly intolerant patients can manage some degree of statin therapy [13]. Statins, the mainstay of lipid-lowering therapy since the 1990s, reduce hepatic production of cholesterol, and are effective at reducing ASCVD events, and are generally well-tolerated [9], but might be associated with adverse effects such as muscle symptoms - which in extreme cases (usually less than 5%) can lead to complete statin intolerance and in the consequence statin discontinuation [10].

The pharmacological treatment of dyslipidemia, a major modifiable risk factor for developing atherosclerotic cardiovascular disease (ASCVD), remains a debated and controversial issue, not only in terms of the most appropriate therapeutic range for lipid levels, but also with regard to the optimal strategy and sequence approach (stepwise vs upstream therapy). Current treatment guidelines for the management of dyslipidemia focus on the intensity of low-density lipoprotein cholesterol (LDL-C) reduction, stratified according to risk for developing ASCVD. Beyond statins and ezetimibe, different medications targeting LDL-C have been recently approved by regulatory agencies with potential innovative mechanisms of action, including proprotein convertase subtilisin/kexin type 9 modulators (monoclonal antibodies such as evolocumab and alirocumab; small interfering RNA molecules such as inclisiran), ATP-citrate lyase inhibitors (bempedoic acid), angiopoietin-like 3 inhibitors (evinacumab), and microsomal triglyceride transfer protein inhibitors (lomitapide). An understanding of their pharmacological aspects, benefit-risk profile, including impact on hard cardiovascular endpoints beyond LDL-C reduction, and potential advantages from the patient perspective (e.g., adherence) - the focus of this evidence-based review - is crucial for practitioners across medical specialties to minimize therapeutic inertia and support clinical practice.

The crosstalk between the renin-angiotensin system and Adenosine monophosphate-activated protein kinase (AMPK) gained significant interest due to their involvement in the pathogenesis of several cardiovascular diseases. Angiotensin II (Ang II) plays a crucial role in developing cardiac remodelling by inducing energy imbalance, inflammation, oxidative and endoplasmic reticulum stress, and transforming growth factor-β (TGF-β)-induced fibrosis. Ang II directly or through extracellular signal-regulated kinase (ERK) activation impairs AMPK signalling with well-known antioxidant, anti-inflammatory, and anti-fibrotic effects. This study aimed to investigate the role of bempedoic acid, a novel antihyperlipidemic drug, in attenuating hypertension-induced cardiac remodelling in rats by modulating Ang II-induced damage and activating the AMPK signalling pathway. Sixty adult male Sprague Dawley rats were randomly allocated into the Sham control group, Hypertensive group, Captopril group (30 mg/kg), and Bempedoic acid group (30 mg/kg). Hypertension was induced by left renal artery ligation in all groups except the Sham control group. Treatment with captopril and bempedoic acid started 14 days post-surgy and lasted two weeks. Finally, Hemodynamic measurements and electrocardiographic examination were done followed by heart tissue samples collection for biochemical, histopathological, and immunohistochemical examinations. Bempedoic acid preserved the cardiac function and electrocardiogram patterns. It inhibited endoplasmic reticulum stress, exhibited antioxidant activity, and increased endothelial nitric oxide synthase activity. Bempedoic acid interfered with ERK signalling pathways, including nuclear factor-κB and TGF-β, exerting anti-inflammatory and anti-fibrotic effects. These findings indicate the cardioprotective and antihypertrophic activity of bempedoic acid, which are suggested to result from energy-independent AMPK downstream signalling activation.

Bempedoic acid significantly lowers low-density lipoprotein cholesterol (LDL-C) in patients with hypercholesterolemia but its effects in patients with metabolic syndrome (MetS) have not been well characterized. We sought to determine the efficacy and safety of bempedoic acid in patients with hypercholesterolemia by baseline MetS status. This study used pooled data from four phase 3 studies. Using modified International Atherosclerosis Society guidelines, patients were grouped into two pools: those with and those without MetS. Patients with diabetes were excluded. Endpoints assessed change from baseline to week 12 in lipid and glycemic parameters and high-sensitivity C-reactive protein (hsCRP), and safety. The study included 936 patients with MetS (bempedoic acid, 648; placebo, 288) and 1573 without MetS (bempedoic acid, 1037; placebo, 536). Significant placebo-corrected reductions in LDL-C were observed with bempedoic acid (p < 0.0001), with a slightly larger decrease in patients with vs. without MetS (−22.3% vs. −18.4%; interaction p = 0.0472). Compared with placebo, bempedoic acid significantly (p < 0.0001) lowered total cholesterol, non–high-density lipoprotein cholesterol, apolipoprotein B, and hsCRP, with a similar magnitude of benefit observed between MetS categories. Triglycerides increased with bempedoic acid but only to a lesser extent than with placebo in patients without MetS (placebo-corrected difference, −4.4%; p = 0.02). Only patients with MetS experienced decreases in glycated hemoglobin (−0.07%; p < 0.0001) and fasting plasma glucose (−2.4 mg/dL; p = 0.002). Safety was comparable between MetS categories and treatment groups. These data suggest that bempedoic acid is a suitable therapy for patients with and without MetS who require additional lipid lowering. [Display omitted] • Bempedoic acid lowered LDL-C vs. placebo in patients with and without MetS. • Bempedoic acid lowered TC, non–HDL-C, ApoB, and hsCRP regardless of MetS category. • Reductions in HbA1c and FPG vs. placebo were only observed in patients with MetS. • Bempedoic acid safety was comparable between MetS categories.

Angiotensin II (Ang II), the effector of the renin-angiotensin system (RAS), is a key player in the pathogenesis of chronic hypertension, accompanied by vascular tissue resistance, remodelling, and damage. Chronic activation of Ang II receptor 1 (AT-1R) impairs multiple cellular targets implicated in cellular protection and survival, including adenosine Monophosphate-activated protein kinase (AMPK) signalling. In addition, it induces oxidative damage, endoplasmic reticulum (ER) stress, and fibrotic changes in resistance vessels. Our study investigated the antihypertensive and antifibrotic effects of bempedoic acid, a first-in-class antihyperlipidemic drug that targets adenosine triphosphate-citrate lyase enzyme to inhibit cholesterol synthesis. We also studied the modulation of multiple AMPK signalling pathways by bempedoic acid in a chronic hypertension model in rats. Sixty male Sprague-Dawley rats were divided into four groups: sham group, hypertensive group, standard captopril group, and bempedoic treated group. All groups underwent left renal artery ligation except the sham group. Fourteen days post-surgery, captopril and bempedoic acid were administered with a dose of 30 mg/kg/day orally to captopril-standard and bempedoic acid-treated groups for two weeks, respectively. In mesenteric resistance arteries, bempedoic acid activated AMPK energy independently and augmented AMPK multiple cellular targets to adapt to Ang II-induced cellular stress. It exerted antioxidant activity, increased endothelial nitric oxide synthase, and reversed the ER stress. Bempedoic acid maintained vascular integrity and prevented vascular remodelling by inhibiting extracellular signal-regulated kinase (ERK)/transforming growth factor-β fibrotic pathway. These effects were reflected in the improved hemodynamic measurements. [Display omitted] [ABSTRACT FROM AUTHOR]

Statins have contributed to the prevention of numerous atherosclerotic cardiovascular (CV) events and cardiovascular deaths in the past three decades. The benefit of statins is mainly mediated by the lowering of LDLc. According to scientific evidence, the current international guidelines recommend very low LDLc goals in patients at high/very high cardiovascular risk because they are associated with fewer CV events and improvements in atherosclerotic plaques. However, these goals often cannot be obtained with statins alone. Recent RCTs have demonstrated that these CV benefits can also be obtained with nonstatin LDLc-lowering drugs such as PCSK9 inhibitors (alirocumab and evolocumab), ezetimibe and bempedoic acid, while evidence with inclisiran is upcoming. Icosapent ethyl, a lipid metabolism modifier, has also shown an effect on event reduction. Physicians should take advantage of the currently available lipid-lowering therapies, choosing the drug or combination of drugs that is most appropriate for each patient according to his or her CV risk and baseline LDLc concentration. Strategies implementing combination therapies from early stages or even from the outset may increase the number of patients attaining LDLc goals, thereby preventing new CV episodes and improving existing atherosclerotic lesions.

The clinical benefit of LDL cholesterol (LDL-C) lowering for cardiovascular disease prevention is well documented. This paper from the Italian Study Group on Atherosclerosis, Thrombosis and Vascular Biology summarizes current recommendations for treatment of hypercholesterolemia, barriers to lipid-lowering therapy implementation and tips to overcome them, as well as available evidence on the efficacy and safety of bempedoic acid. We also report an updated therapeutic algorithm for pharmacological LDL-C lowering in view of the introduction of bempedoic acid in clinical practice. [Display omitted] [ABSTRACT FROM AUTHOR]

The dysregulation of the activity of histone deacetylase 6 (HDAC6) is observed in a number of human diseases. Targeting HDAC6 has been identified as an ideal treatment strategy in epigenetic-based therapies. Bempedoic acid is an FDA-approved cholesterol-lowering medication. In the present study, bempedoic acid was repurposed as an HDAC6 inhibitor for the first time, at least to the best of our knowledge. Bempedoic acid inhibited the activity of HDAC6 in vitro with an IC50 value of ~0.8 mM. In silico analysis predicted the formation of hydrogen bonds and hydrophobic interactions between HDAC6 residues and bempedoic acid, which may be attributed to its HDAC6 inhibitory potential. The results of the present study provide new opportunities to bring bempedoic acid into epigenetic-based drug discovery platforms. [ABSTRACT FROM AUTHOR]

• • ACLY was firstly demonstrated to be significantly increased in PDGF-BB induced dedifferentiated smooth muscle cells. • • Bempedoic acid significantly reduced ACLY expression and inhibited VSMC dedifferentiation in the wire-injured mouse femoral arteries, resulting in reduced neointima formation. • • Bempedoic acid restrained PDGF-BB-stimulated VSMC proliferation and dedifferentiation by activating AMPKα/ACC signaling pathway, which may provide a potential therapeutic strategy for diseases associated with intimal hyperplasia including restenosis and atherosclerosis. One of the common pathophysiological basis of atherosclerosis is intimal hyperplasia. ATP citrate lyase (ACLY) has been reported as a promising therapeutic target for treatment of dyslipidemia and atherosclerosis. However, the role of ACLY in intimal hyperplasia has yet to be clarified. The current investigation studies the molecular effects of ACLY and bempedoic acid, an ACLY inhibitor, on platelet-derived growth factor (PDGF)-induced primary human aortic smooth muscle cells (HASMCs) proliferation in vitro and on femoral arterial wire-injured neointimal hyperplasia in mouse in vivo. The role of ACLY in intimal hyperplasia was further investigated in mice treated with bempedoic acid. Cell proliferation was measured by CCK8 and BrdU assays. We explored further mechanisms using western blot, qPCR and immunofluorescence. We found that ACLY was significantly increased in dedifferentiated VSMC in vitro and vivo. Bempedoic acid which can inhibit ACLY expression effectively blocked PDGF-induced VSMC proliferation and dedifferentiation by activating AMPK/ACC signaling pathway. Moreover, bempedoic acid also attenuated VSMC proliferation and inhibited VSMC dedifferentiation in the wire-injured mouse femoral arteries, resulting in reduced neointima formation. We demonstrates that bempedoic acid reduces ACLY expression to restrain VSMC proliferation and dedifferentiation by activating AMPK/ACC signaling pathway, which may provide a potential therapeutic strategy for diseases associated with intimal hyperplasia including restenosis and atherosclerosis.
