Abstract
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.

Introduction
Atherosclerotic cardiovascular disease (ASCVD) is a major cause of global mortality and dyslipidaemia is a key mechanism in establishing ASCVD. Indeed, ASCVD remains the primary cause of mortality and disability among patients with diabetes mellitus. Data from the WHO Multinational Study of Vascular Disease in Diabetes (WHO MSVDD) study demonstrated that cardiovascular disease was the most prevalent cause of death in type 1 diabetes mellitus (44%) and type 2 diabetes mellitus (52%) [1]. A number of studies confirmed the significance of diabetes mellitus as an ASCVD risk factor and demonstrated it as a similar risk equivalent those with established ASCVD without diabetes [2, 3].
There is an overwhelming amount of data in support of low-density lipoprotein cholesterol (LDL-C) as a risk factor for ASCVD. A number of population-based studies have demonstrated that optimal total cholesterol levels are about 150 mg/dl (3.8 mmol/l); this parallels an LDL-C status of approximately 100 mg/dl (2.6 mmol/l) [4, 5]. Indeed, statin therapy, which primarily targets the LDL-C pathway, has a wealth of data expanding over the last three decades demonstrating its considerable efficacy in the prevention of ASCVD and death [6, 7]. In addition, ASCVD benefits from statin therapy are primarily related to absolute LDL-C lowering [8]. Statins are recommended as first-line therapy in both primary and secondary prevention cohorts through the prevention of ASCVD [9] and are one of the foundations of multi-risk factor therapy in diabetes mellitus. Indeed, studies of statins in diabetes demonstrate significant reductions in both coronary and cerebrovascular events [10,10,12]. The American Diabetes Association Standards of Medical Care in Diabetes (US) and the National Institute of Health and Care Excellence (NICE) (UK) both advocate a priority of lowering LDL-C primarily through moderate intensity statin therapy [13,13,15].
For LDL-C lowering, statins are certainly the drugs of choice due to the wealth of conclusive evidence including hard cardiovascular outcomes. However, regarding statin intolerance there has been a disparity about the true incidence of side effects of statins and possible harm from these side effects [16]. Randomised controlled clinical trials report very low rates of even the most well-authenticated side effects, such as myopathy [17]. However, in uncontrolled observational studies muscle symptoms are reported in as many as 10–20% of statin recipients [18,18,19,20,21,22,24]. Current evidence also suggests that statins are associated with a ‘diabetogenic’ potential by increasing the risk of new-onset diabetes and worsening established diabetes through a modest increase in glycaemic levels [25,25,27].
Previous reports outlined the risk of new-onset diabetes in statin treatment which was increased by 9% compared to those taking placebo, whilst intensive and cumulative statin therapy was also associated with an increased risk of diabetes development [26]. Although the mechanism by which statins increase the incidence of diabetes are not fully established, evidence suggests a multi-factorial cause involving the inhibition of β-cell glucose transporters, delayed ATP production, pro-inflammatory and oxidative β-cell effects of plasma-derived cholesterol, inhibition of calcium channel-dependent insulin secretion and β-cell apoptosis [25].
The paradox is raised wherein statins, which represent the strongest form of cardiovascular risk reduction, may promote progression to diabetes. However, the benefits of continued statin therapy very much outweigh the potential diabetogenic risks, the introduction of novel lipid-lowering agents may provide a possible solution for those at high risk of diabetes, e.g. prediabetes/metabolic syndrome groups with statin intolerance given its lack of deleterious effect on glycaemic control. Hence, there is a current clinical need for an effective alternative to statin therapy for LDL-C-lowering.
This short review provides a succinct narrative of the future role and current trial data of the novel first-in-class molecule, bempedoic acid, in the management of ASCVD and dyslipidaemia, with consideration of the excess of ASCVD in diabetes mellitus.
Methods
The authors provide their expert insight; in addition, a literature search was undertaken on bempedoic acid in PubMed, Google Scholar and clinicaltrials.gov to ensure relevant trials were discussed. The authors primarily focussed on phase III randomised controlled trials (RCT) of bempedoic acid. All seven available phase III trials were reviewed, and four trials were chosen based on completion with published and analysed results. This article is based on previously conducted studies and does not contain novel data of animal and human study origin.
Results
Of seven phase III trials that evaluated bempedoic acid, four have been completed and published: Cholesterol Lowering via Bempedoic Acid, an ACL-Inhibiting Regimen (CLEAR) Harmony (NCT02666664), CLEAR Wisdom (NCT02991118), CLEAR Tranquillity (NCT03001076) and CLEAR Serenity (NCT02988115). Table 1 outlines the primary characteristics of these studies. Of the remaining three trials, one is currently in process and two have been completed but are yet to be published and for the purpose of this review have not been discussed [28]. All of the available trial data demonstrate significant LDL-C reductions.
Phase III trials have demonstrated the efficacy of bempedoic acid 180 mg once daily in reducing LDL-C compared to placebo. The CLEAR Harmony trial evaluated the efficacy and safety of bempedoic acid 180 mg once daily (n = 1488) versus placebo (n = 742) in patients with ASCVD and/or heterozygous familial hypercholesterolaemia (HeFH) receiving maximal dose of tolerated statins over 52 weeks [29]. At week 12, bempedoic acid reduced the mean LDL-C level by 19.2 mg/dl (0.50 mmol/l) representing 16.5% reduction from baseline (P < 0.001). Adverse event and serious adverse event rates were similar in the bempedoic acid group compared to the placebo group (78.5 vs. 78.7% and 14.5% vs. 14.0% respectively). However, the incidence of adverse events leading to discontinuation was significantly higher in the bempedoic acid group (10.9%) than in the placebo group (7.1%), as was the incidence of gout (1.2% vs. 0.3% respectively). Similar data with a significant reduction of LDL-C with bempedoic acid 180 mg once daily compared to placebo were reported in the CLEAR Wisdom trial.
CLEAR Harmony and CLEAR Wisdom assessed the safety and tolerability of 180 mg once daily bempedoic acid versus placebo in patients with high cardiovascular risk and elevated LDL cholesterol not adequately controlled by their current maximally tolerated statin therapy [29, 30]. Both trials were of 52 weeks duration. At 12 weeks bempedoic acid reduced the mean placebo corrected LDL-C by −16.5% (CLEAR Harmony) and −17.4% (CLEAR Wisdom) from baseline [29, 30] and showed no greater risk of adverse events compared to placebo CLEAR (Harmony; 78.5% versus 78.7%, CLEAR Wisdom; 70.1% versus 70.8%) [29, 30]. CLEAR Tranquillity observed the safety and efficacy of bempedoic acid added to ezetimibe in statin-intolerant patients with hypercholesterolaemia [31]. In this 12-week trial, bempedoic acid added to ezetimibe reduced LDL-C by 28.5% more than placebo (p < 0.001; − 23.5% bempedoic acid, + 5.0% placebo) [31]. The efficacy and safety of bempedoic acid in patients with statin intolerance were also studied in the CLEAR Serenity trial of 24 weeks duration [32]. Patients with a history of intolerance two statins (one at the lowest available dose) were randomised (2:1) to either 180 mg once daily bempedoic acid or placebo once daily [32]. At week 12 bempedoic acid treatment significantly lowered LDL-C by a placebo corrected − 21.4% (95% CI − 25.1 to − 17.7%; p < 0.001) [32].
Across all four trials bempedoic acid was well tolerated [33]. Common adverse events included gout, urinary tract infections, nasopharyngitis and hyperuricaemia [29,29,30,32]. In CLEAR Harmony, the incidence of new-onset diabetes or worsening diabetes was lower in the treatment arm compared to placebo (n = 49 [3.3%] vs. n = 40 [5.4%]) [29]. CLEAR wisdom found that amongst patients with diabetes, HbA1c decreased by 0.08% from baseline in the bempedoic acid cohort, whilst levels increased by 0.13% in the placebo cohort [30]. Favourable glycaemic control included a reduction in worsening was consistent over the 1-year treatment period.
In CLEAR Tranquillity, 2.3% of patients in the placebo arm developed diabetes compared to 1.1% of patients in the intervention arm [31]. Similarly, new-onset or worsening diabetes was less commonly seen in the bempedoic acid treatment arm (2.1%) compared to placebo (4.5%) in the CLEAR Serenity trial [32]. Fasting glucose ≥ 126 mg/dl and glycosylated haemoglobin ≥ 6.5% (48 mmol/mol) was less frequently observed in individuals in the bempedoic acid cohort regardless of pre-existing diabetes compared to placebo [32].
A recent meta-analysis combined the outcome of new-onset or worsening diabetes in these four trials which reported 3.7% of individuals taking bempodic acid compared to 5.7% of individuals on placebo [34]. Bempodeic acid was associated with a risk reduction of 0.65 (95% CI 0.44–0.96; I2 = 23%) [34].
Discussion
Bempedoic acid (NEXLETOL® in the USA, Nilemdo® in the EU) (Diiachi Sankyo; Esperion) (ETC-1002; ESP55016) is a first-in-class small molecule, delivered as a prodrug and administered as an oral, once-daily dose that decreases LDL-C level. It was approved by both the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) in February and March 2020 respectively [35]. Bempedoic acid is administered orally in one 180 mg dose licensed by the FDA as an addition to maximally tolerated statin treatment in adults with HeFH or established ASCVD who require additional lowering of LDL-C (US label). In the EU, the licensed indication differs slightly and is indicated in adults with primary hypercholesterolaemia (HeFH/non-familial) or mixed dyslipidaemia in combination with a statin with or without other lipid-lowering therapies in people unable to meet LDL-C targets with maximal statin treatment alone or in combination with other lipid-lowering therapies in people who are statin intolerant or for whom a statin is contraindicated (please see the British National Formulary: https://bnf.nice.org.uk/drug/bempedoic-acid.html).
Bempedoic acid is a prodrug. The activated substance inhibits adenosine triphosphate citrate lyase, which is involved in the cholesterol biosynthesis in the liver upstream of β-hydroxy β-methylglutaryl-CoA (HMG-CoA) reductase, the enzyme that is antagonised by statins. Similar to statins, bempedoic acid depletes intracellular cholesterol leading to upregulation of hepatic LDL receptor expression, thus increasing the clearance of circulating LDL-C. However, this is where the similarities diverge and the activation through primarily liver enzymes (very long-chain acyl-CoA synthetase-1, which lacks expression in skeletal muscle) is postulated to lessen the risk of myopathy and musculoskeletal-related side effects. Experimental and clinical data suggest that bempedoic acid has anti-atherosclerotic effects [36], improvement in glucose homeaostasis [37], inflammation and blood pressure [38] in addition to its LDL-C-lowering activity [37]. Recently, a systematic review and meta-analysis of seven clinical trials confirmed its anti-inflammatory effect demonstrated by a reduction in high-sensitivity c-reactive protein (hsCRP) [mean difference compared to controls: − 13.2%; 95% CI − 16.7% to − 9.79%; P < 0.001]. Given the accepted role of inflammation and hsCRP as a surrogate biomarker of systemic inflammation and the prediction of ASCVD [39], these findings may be of prognostic benefit, which needs to be further interrogated in in vivo mechanistic and post-marketing studies. Bempedoic acid’s primary anti-atherosclerotic benefit is through lowering LDL-C; however, clearly its anti-inflammatory effect may be also clinically relevant. Interestingly, LDL-C reduction with evolocumab (a PCSK9 inhibitor) reduced absolute risk of ASCVD in patients with higher baseline hsCRP [40]. Also, in healthy persons without hyperlipidaemia but with high hsCRP levels, LDL-C lowering with rosuvastatin significantly reduced the incidence of major ASCVD events [41].
Lipid-lowering therapy targeting the reduction of LDL-C reduces the risk of cardiovascular disease and LDL-C also remains one of the best biomarkers for ASCVD. However, it should be noted that the value of LDL-C as a surrogate endpoint for ASCVD is not absolute given its heterogeneous nature with differences in outcomes in LDL-C-lowering drug effects [42]. For instance, the use of fibrates as lipid-lowering therapyhas demostrated no significant cardiovascular benefit [43]. Nonetheless, other drugs such as bempedoic acid and ezetimibe have shown favourable cardioprotective outcomes [34, 43]. Given the undisputed causal relationship between LDL-C and ASCVD [8] with no known level below which further LDL-C lowering ceases to be beneficial [44], the significant LDL-C reduction with bempedoic acid provides clear hope and the expectation that these data will be translated into a reduction in ASCVD events and subsequent mortality. Importantly, the CLEAR Outcomes trial (NCT02993406) is precisely evaluating hard ASCVD endpoints in statin-intolerant patients or patients at high risk of ASCVD and is currently underway; its future results are eagerly awaited.
A number of phase III trials have shown the efficacy of bempedoic acid 180 mg once daily in reducing LDL-C compared to placebo. This article has focussed on four phase III trials under the CLEAR trials umbrella including Harmony, Wisdom, Tranquillity and Serenity. Collectively evidence from these trials has shown reductions in LDL-C baseline of up to approximately 24% after 12 weeks and was generally well tolerated throughout the treatment length. Importantly, the magnitude of LDL-C reduction in the CLEAR Serenity trial is similar to that of low-intensity statins (simvastatin 10 mg, lovastatin 20 mg, pravastatin 20 mg, fluvastatin 40 mg) [6]. All of the aforementioned trials have demonstrated an improvement in systemic inflammation with a reduction in hsCRP and a reduction in new onset or worsening of diabetes. In addition to the CLEAR Tranquillity trial, another study has shown efficacy and safety in combination with ezetimibe [45]. Based on these data a fixed dose combination of bempedoic acid (180 mg) and ezetimibe (10 mg) (NEXLIZET® in the US, Nustendi® in the EU) has been released [35]. Despite no direct head-to-head comparison with statins, the overall musculoskeletal-related adverse events seem to be lower providing an alternative pharmacotherapy in statin-intolerant patients [46].
A further recent meta-analysis demonstrated a decreased risk of new-onset or worsening of type 2 diabetes (odds ratio 0.59; 95% CI 0.39–0.90; P = 0.01) [33]. Clearly, this in contrast to statin therapy, which is associated with an small increase in the absolute risk of new-onset type 2 diabetes [47]. Although the currently published CLEAR series of trials had reported improvement of hyperglycaemia and reduction of worsening or new-onset diabetes, most of the trials did not display a statistically significant trend. Also, across these trials, patients and events of interest were few. Indeed, people with diabetes ranged between 20 and 30% of the full trial cohorts, however there was no specific focus on prediabetic groups or groups at high risk of progession to diabetes. Further research in cohorts in metabolic syndrome or prediabetes with the specific intent to delineate any putative beneficial anti-glycaemic effect requires further study. Whilst bempedoic acid has demonstrated promising outcomes, it is important to note that statin therapy remains the primary lipid-lowering therapy according to international consensus [48,48,50].
Adherence to statins is a known challenge, particularly amongst patients taking low-intensity treatment. A large retrospective cohort study reported adherence levels of 84% after 1 year of treatment in patients on high-intensity treatment with CVD compared with adherence of only 57% in patients on low-intensity treatment [51]. After 6 years of therapy, adherence rates in both groups dropped further to 72% and 48% in the high- and low-intensity cohorts respectively [51]. These results were supported by a more recent study which retrospectively observed patients from 2009 to 2016; overall, approximately 53% of patients were adherent to statin therapy [52]. Adherence and discontinuation were related to intensity levels with patients on high-intensity therapy being more adherent (63.7%) and less likely to discontinue treatment compared to those on moderate- or low-intensity therapy [52].
The adherence to therapy is fundamental to maximal possible reduction of cardiovascular risk. Average risk reduction of cardiovascular events is about 40% and 22% in patients adhering to high- or low-intensity statin therapy respectively [51]. This is compared to a risk reduction of only 10% in high-intensity treatment and 5% in low-intensity treatment in patients with poor compliance [51].
Currently injectable therapy, e.g. PCSK9 inhibitors such as evolocumab, is an alternative to statin therapy in patients with poor compliance. It is given every 2 weeks and indicated in patients with high cardiovascular risk and/or primary HeFH and persistently raised LDL-C [53]. However, its use is limited by cost [43]. The issue of cardiovascular risk benefit in relation to compliance poses the question of whether adherence and thus cardiovascular risk would be improved with newer and potentially, more cost-effective therapy options such as bempedoic acid. However, a meta-analysis observed a 37% discontinuation rate of bempedoic acid compared to placebo. There was no pattern that could explain the increased risk of discontinuation and thus this needs to be further investigated [33].
Conclusions
Currently, many patients do not achieve the desired reduction in LDL-C, particularly in severe hyperlipidaemias, in individuals who do not tolerate the first-line statin therapy and even in general diabetes cohorts [54]. Therefore, addition of bempedoic acid to the array of lipid-lowering therapies is most welcome particularly given the high prevalence of ASCVD in diabetes mellitus. Indeed NICE technology appraisal guidance [TA694] has 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. The approval of the novel first-in-class drug, bempedoic acid, has added to the armoury of lower LDL-C-lowering therapy available to physicians treating dyslipidaemia and ASCVD.
