Genetic association of lipids and lipid-lowering drug target genes with Endometrial carcinoma: a drug target Mendelian randomization study.

Background: Aberrant lipid metabolism is intricately linked to the development of endometrial cancer, and statin lipid-lowering medications are regarded as promising adjunctive therapies for future management of this malignancy. This study employed Mendelian randomization (MR) to explore the causal association between lipid traits and endometrial cancer while assessing the potential impact of drug targets on lower lipids on endometrial cancer. Method: Two-sample Mendelian randomization was employed to probe the causal association between lipid traits and endometrial carcinoma. Drug-target Mendelian randomization was also utilized to identify potential drug-target genes for managing endometrial carcinoma. In instances where lipid-mediated effects through particular drug targets were notable, the impacts of these drug targets on endometrial carcinoma risk factors were investigated to bolster the findings. Result: No causal association between genetically predicted lipid traits (LDL-C, TG, TC, and HDL-C) and EC was found in two-sample Mendelian randomization. In drug target Mendelian randomization, genetic modeling of apolipoprotein B (APOB) (OR [95%CI]=0.31, [0.16-0.60]; p=4.73e-04) and cholesteryl ester transfer protein (CETP) (OR [95%CI]=1.83, [1.38-2.43]; p=2.91e-05) genetic mimicry was associated with non-endometrioid carcinoma. Conclusion: The results of our MR study revealed no causal association between genetically predicted lipid traits (LDL-C, TG, TC, and HDL-C) and EC. Among the six lipid-lowering drug targets, we observed a significant association between lower predicted APOB levels and higher CETP levels with an increased risk of endometrioid carcinoma. These findings provide novel insights into the importance of lipid regulation in individuals with endometrial carcinoma, warranting further clinical validation and mechanistic investigations.

Lomitapida no tratamento da Hipercolesterolemia Familiar Homozigótica / Lomitapide is not treated for Homozygous Familial Hypercholesterolemia

INTRODUÇÃO: A hipercolesterolemia familiar homozigótica (HFHo) é uma doença rara, com uma prevalência estimada em 1:1.000.000, e é caracterizada pelos altos níveis de colesterol de lipoproteínas de baixa densidade (LDL-C) devido uma alteração genética que faz com que os receptores de LDL (LDL-R) tenham função diminuída ou quase nula. Esta característica da doença faz com que as terapias hipolipemiantes, recomendadas para as dislipidemias, não sejam muito efetiva em baixar os níveis de LDL-C e ocasionando, em uma exposição de longo período, doenças cardiovasculares (DCV) ateroscleróticas precocemente. Desta forma, novas alternativas como o mesilato de lomitapida, estão surgindo como uma possível opção de diminuir os eventos cardiovasculares (ECV), com a diminuição dos níveis de LDL-C no organismo. TECNOLOGIA: Mesilato de lomitapida. PERGUNTA DE PESQUISA: A lomitapida é eficaz e segura na redução dos níveis de LDL-C em pacientes adultos com hipercolesterolemia familiar homozigótica que, com o uso dos tratamentos atualmente disponibilizados pelo SUS, não conseguem atingir níveis plasmáticos de LDL-C considerados aceitáveis para essa doença? EVIDÊNCIAS CIENTÍFICAS: Há 9 estudos apresentados como evidência. Um estudo de escalonamento de dose; 2 ensaios clínicos de braço único, 1 (pivotal) com n=29, e outro com n=9 realizado na população japonesa; 2 estudos de extensão dos ensaios clínicos com perda significativa da amostra ao longo do seguimento dos ensaios; 2 estudos observacionais, retrospectivos, 1 com n=15 na população italiana e 1 com n=75 realizado na Europa; 1 estudo observacional com base de registro (LOWER study) que conseguiu dados de 185 pacientes com HFHo, que foram expostos a diversos tratamento, incluindo lomitapida (n=67); e 1 série de 12 casos. Todos os estudos tiveram resultados significativos, com diminuição de aproximadamente 50% sobre os níveis de LDL-C pré versus pós uso do medicamento. Mesmo considerando que é uma doença rara e a dificuldade de se realizar ensaios clínicos com maior rigor, é necessário considerar que, os estudos apresentaram alto risco de viés, os valores na redução do LDL-C apresentam grande variação, a evidência é indireta pois a intervenção nos estudos tem terapêuticas associadas e variável entre e dentro do estudo, há imprecisão, e, implícito à doença ser rara, pequeno número de indivíduos na amostra, e não há como identificar ou avaliar qualquer viés de publicação. Além disso, as evidências analisam um desfecho intermediário, nível de LDL-C e não há desfechos clínicos relevantes. Desta forma, o grau de recomendação é fraco contra a tecnologia. AVALIAÇÃO ECONÔMICA (AE): Foi realizado uma análise de custo-efetividade, comparando o lomitapida + atorvastatina versus atorvastatina, na população de pacientes portadores de HFHo, e para estimar os anos de vida ganhos, desfechos de mortalidade, e eventos cardiovasculares maiores foram estimados por cálculos que se basearam na diminuição dos níveis de LDL-C. Foi utilizado um modelo de Markov, com ciclo anual, para simular a análise ao longo da vida. Os custos foram obtidos pela perspectiva do SUS através do levantamento dos custos pelas bases públicas. A razão de custo-efetividade incremental (RCEI) foi de R$ 4.529.892,89 por ano de vida ganho (R$ 1.877.446,00 a R$ 20.528.480,00), que foi bastante sensível ao tamanho do efeito, sobre a diminuição dos níveis séricos do LDL-C. ANÁLISE DE IMPACTO ORÇAMENTÁRIO (AIO): Baseado em uma prevalência de 1:1 milhão, há ~160 pacientes adultos portadores de HFHo no Brasil. Destes, nem todos serão diagnosticados e tratados, estima-se que no primeiro ano, somente 11 pacientes farão uso da lomitapida, e que ao longo de 5 anos, um total de 35 pacientes farão uso da tecnologia por ano. Desta forma, o impacto orçamentário (IO) incremental seria de R$ 13.381.712,00 no primeiro ano e de R$ 29.212.587,00 no quinto ano, com um impacto orçamentário acumulado dos cinco anos de R$ 108.450.319,00 para o SUS. CONSIDERAÇÕES FINAIS: A HFHo é uma doença rara, que dificulta a execução de ensaios clínicos de maior qualidade metodológica. Os estudos apresentados, a maioria sem grupo comparador e todos com uso de terapia associada, apresentaram uma importante redução nos níveis de LDL-C (~50%). No entanto, desfechos duros de ECV maiores e mortalidade não estão disponíveis, que conduzem a uma interpretação da evidência de fraca recomendação contra a tecnologia. O estudo de custo-efetividade, assumem pressupostos com alto grau de incerteza, com estimativas de desfechos duros advindos de medidas de eficácia superestimadas. A análise de impacto econômico pode estar subestimada, devido as estimativas serem bastante incertas e ao alto custo da tecnologia por indivíduo tratado. RECOMENDAÇÃO PRELIMINAR DA CONITEC: o Plenário da Conitec, em sua 113ª Reunião Ordinária, no dia 06 de outubro de 2022, deliberou que a matéria fosse disponibilizada em Consulta Pública com recomendação preliminar desfavorável à incorporação do mesilato de lomitapida para o tratamento da hipercolesterolemia familiar homozigótica em pacientes adultos (>18 anos) no SUS. Os membros da Conitec consideraram que apesar das evidências apresentadas, e mesmo entendendo a importância do medicamento no controle dos níveis de LDL-C frente a uma doença rara, a lomitapida apresenta riscos hepáticos que devem ser levados em consideração, principalmente, os aspectos econômicos como fator limitante à sua incorporação ao SUS. CONSULTA PÚBLICA: A Consulta Pública nº 71 foi realizada entre os dias 03/11/2022 a 22/11/2022. Foram recebidas 32 contribuições, sendo 8 pelo formulário para contribuições técnico-científicas e 24 pelo formulário para contribuições sobre experiência ou opinião de pacientes, familiares, amigos ou cuidadores de pacientes, profissionais de saúde ou pessoas interessadas no tema. Todas as contribuições técnico-científicas indicaram discordância à recomendação preliminar da Conitec e discutiram os desfechos de eficácia e segurança, bem como sobre o desenho dos estudos selecionados, sem apresentar novas evidências à síntese. O demandante propôs um "preço fixo", ou seja, uma garantia de que os custos do tratamento de cada paciente serão iguais ao preço da dose de 20 mg para pacientes que precisam usar doses de 40 ou 60 mg por dia. Nas contribuições de experiência e opinião, todos os 24 participantes manifestaramse favoráveis à incorporação da tecnologia avaliada e, portanto, em discordância com a recomendação preliminar da Conitec. Entre os argumentos favoráveis à incorporação da lomitapida no SUS foram destacados o fato de o medicamento configurar-se como opção terapêutica com indicação aprovada para o tratamento de HFHo e ter um custo elevado para o paciente. A maioria dos participantes destacou a redução eficaz dos níveis de colesterol, a diminuição de eventos cardiovasculares e a comodidade posológica como efeitos positivos e facilidades relacionados à lomitapida. Sobre os efeitos negativos e dificuldades, foram referidos o alto custo da tecnologia avaliada e o risco de efeitos adversos, sobretudo, danos hepáticos. No que diz respeito à experiência com outras tecnologias, os participantes citaram predominantemente o uso de medicamentos, tais como ezetimiba, rosuvastatina cálcica, mipomersen, evolucumabe e atorvastatina para o tratamento de HFHo. A redução variável dos níveis de colesterol, a segurança e o custo acessível foram referidos como efeitos positivos e facilidades dessas tecnologias, enquanto a baixa eficácia foi considerada como efeito negativo. RECOMENDAÇÃO FINAL DA CONITEC: Pelo exposto, o Plenário da Conitec, em sua 12ª Reunião Ordinária, no dia 29 de novembro de 2022, deliberou por unanimidade recomendar a não incorporação de mesilato de lomitapida para o tratamento de Hipercolesterolemia Familiar Homozigótica em pacientes adultos (>18 anos), no SUS. Os membros da Conitec consideraram que apesar de apresentados novos esclarecimentos sobre a eficácia e segurança do medicamento e, ainda que recebida uma nova proposta de bonificação, o impacto econômico permaneceu como fator limitante à sua incorporação. Por fim, foi assinado o Registro de Deliberação nº 787/2020. DECISÃO: Não incorporar, no âmbito do Sistema Único de Saúde - SUS, o mesilato de lomitapida para o tratamento da Hipercolesterolemia Familiar Homozigótica em pacientes adultos (>18 anos), conforme a Portaria nº 2, publicada no Diário Oficial da União nº 19, seção 1, página 42, em 26 de janeiro de 2023.

Comparative Reductions in Investigator-Reported and Adjudicated Ischemic Events in REDUCE-IT.

BACKGROUND: REDUCE-IT (Reduction of Cardiovascular Events With Icosapent Ethyl-Intervention Trial) randomized statin-treated patients with elevated triglycerides to icosapent ethyl (IPE) or placebo. There was a significant reduction in adjudicated events, including the primary endpoint (cardiovascular [CV] death, myocardial infarction [MI], stroke, coronary revascularization, unstable angina requiring hospitalization) and key secondary endpoint (CV death, MI, stroke) with IPE. OBJECTIVES: The purpose of this study was to determine the effects of IPE on investigator-reported events. METHODS: Potential endpoints were collected by blinded site investigators and subsequently adjudicated by a blinded Clinical Endpoint Committee (CEC) according to a prespecified charter. Investigator-reported events were compared with adjudicated events for concordance. RESULTS: There was a high degree of concordance between investigator-reported and adjudicated endpoints. The simple Kappa statistic between CEC-adjudicated vs site-reported events for the primary endpoint was 0.89 and for the key secondary endpoint was 0.90. Based on investigator-reported events in 8,179 randomized patients, IPE significantly reduced the rate of the primary endpoint (19.1% vs 24.6%; HR: 0.74 [95% CI: 0.67-0.81]; P < 0.0001) and the key secondary endpoint (10.5% vs 13.6%; HR: 0.75 [95% CI: 0.66-0.85]; P < 0.0001). Among adjudicated events, IPE similarly reduced the rate of the primary and key secondary endpoints. CONCLUSIONS: IPE led to consistent, significant reductions in CV events, including MI and coronary revascularization, as determined by independent, blinded CEC adjudication as well as by blinded investigator-reported assessment. These results highlight the robust evidence for the substantial CV benefits of IPE seen in REDUCE-IT and further raise the question of whether adjudication of CV outcome trial endpoints is routinely required in blinded, placebo-controlled trials.

Investigating Lipid-Modulating Agents for Prevention or Treatment of COVID-19: JACC State-of-the-Art Review.

Coronavirus disease-2019 (COVID-19) is associated with systemic inflammation, endothelial activation, and multiorgan manifestations. Lipid-modulating agents may be useful in treating patients with COVID-19. These agents may inhibit viral entry by lipid raft disruption or ameliorate the inflammatory response and endothelial activation. In addition, dyslipidemia with lower high-density lipoprotein cholesterol and higher triglyceride levels portend worse outcomes in patients with COVID-19. Upon a systematic search, 40 randomized controlled trials (RCTs) with lipid-modulating agents were identified, including 17 statin trials, 14 omega-3 fatty acids RCTs, 3 fibrate RCTs, 5 niacin RCTs, and 1 dalcetrapib RCT for the management or prevention of COVID-19. From these 40 RCTs, only 2 have reported preliminary results, and most others are ongoing. This paper summarizes the ongoing or completed RCTs of lipid-modulating agents in COVID-19 and the implications of these trials for patient management.

Efficacy and safety of PXL770, a direct AMP kinase activator, for the treatment of non-alcoholic fatty liver disease (STAMP-NAFLD): a randomised, double-blind, placebo-controlled, phase 2a study.

BACKGROUND: AMP kinase (AMPK) is an energy sensor implicated in regulation of lipid metabolism, inflammation, and insulin sensitivity. We aimed to assess efficacy and safety of PXL770, a novel direct AMPK activator, in patients with non-alcoholic fatty liver disease (NAFLD). METHODS: STAMP-NAFLD, a randomised, double-blind, placebo-controlled phase 2a study, was done across 15 US clinical sites. Patients aged 18-75 years with liver fat content of at least 10% at baseline when assessed by MRI-proton density fat fraction (MRI-PDFF) were eligible. Patients were randomly assigned (1:1:1:1), via an interactive web response system, to receive oral PXL770 250 mg once daily, 250 mg twice daily, or 500 mg once daily, or matched placebo. Patients were stratified according to type 2 diabetes status and study site. The primary endpoint was relative change in liver fat content from baseline compared with placebo at week 12, assessed by MRI-PDFF. The primary endpoint was analysed in an ANCOVA model with treatment and stratification criteria as factors and baseline liver fat content as a covariate in the modified intention-to-treat population, defined as all as-randomised patients who received at least one dose of study treatment. Safety was analysed in the safety population, defined as all as-treated patients receiving at least one dose of the study treatment. The trial has been completed and the final results are reported. The trial is registered with ClinicalTrials.gov, NCT03763877. FINDINGS: Between March 29, 2019, and March 13, 2020, 387 patients were screened, of whom 120 were included in the modified intention-to-treat and safety analyses (30 in the 250 mg once daily group, 30 in the 250 mg twice daily group, 29 in the 500 mg once daily group, and 31 in the placebo group). The mean relative change from baseline in liver fat content at week 12 was -1·1% in the placebo group, -1·0% in the 250 mg once daily group (mean difference versus placebo 0·1% [95% CI -15·4 to 15·7], p=0·99), -14·3% in the 250 mg twice daily group (-13·1% [-28·1 to 1·8], p=0·084), and -14·7% in the 500 mg once daily group (-13·5% [-28·5 to 1·4], p=0·076). At least one treatment-emergent adverse event occurred in 23 (77%) of 30 patients in the 250 mg once daily group, 20 (67%) of 30 patients in the 250 mg twice daily group, 21 (72%) of 29 patients in the 500 mg once daily group, and 21 (68%) of 31 patients in the placebo group. The most common treatment-emergent adverse event was diarrhoea (five [17%] of patients in the 250 mg once daily group, seven [23%] in the 250 mg twice daily group, six [21%] in the 500 mg once daily group, and none in the placebo group). No life-threatening events or treatment-related deaths occurred. INTERPRETATION: PXL770 treatment did not meet the primary outcome of liver fat improvement compared with placebo. Treatment was well tolerated. Given indications that metabolic features improved with PXL770 treatment, AMPK activation might be a promising pharmacological target for patients with type 2 diabetes and NAFLD, and could also be considered for further assessment in patients with non-alcoholic steatohepatitis.

Using Consistently Low Performance to Identify Low-Quality Physician Groups.

Importance: There has been a growth in the use of performance-based payment models in the past decade, but inherently noisy and stochastic quality measures complicate the assessment of the quality of physician groups. Examining consistently low performance across multiple measures or multiple years could potentially identify a subset of low-quality physician groups. Objective: To identify low-performing physician groups based on consistently low performance after adjusting for patient characteristics across multiple measures or multiple years for 10 commonly used quality measures for diabetes and cardiovascular disease (CVD). Design, Setting, and Participants: This cross-sectional study used medical and pharmacy claims and laboratory data for enrollees ages 18 to 65 years with diabetes or CVD in an Aetna health insurance plan between 2016 and 2019. Each physician group's risk-adjusted performance for a given year was estimated using mixed-effects linear probability regression models. Performance was correlated across measures and time, and the proportion of physician groups that performed in the bottom quartile was examined across multiple measures or multiple years. Data analysis was conducted between September 2020 and May 2021. Exposures: Primary care physician groups. Main Outcomes and Measures: Performance scores of 6 quality measures for diabetes and 4 for CVD, including hemoglobin A1c (HbA1c) testing, low-density lipoprotein testing, statin use, HbA1c control, low-density lipoprotein control, and hospital-based utilization. Results: A total of 786 641 unique enrollees treated by 890 physician groups were included; 414 655 (52.7%) of the enrollees were men and the mean (SD) age was 53 (9.5) years. After adjusting for age, sex, and clinical and social risk variables, correlations among individual measures were weak (eg, performance-adjusted correlation between any statin use and LDL testing for patients with diabetes, r = -0.10) to moderate (correlation between LDL testing for diabetes and LDL testing for CVD, r = .43), but year-to-year correlations for all measures were moderate to strong. One percent or fewer of physician groups performed in the bottom quartile for all 6 diabetes measures or all 4 cardiovascular disease measures in any given year, while 14 (4.0%) to 39 groups (11.1%) were in the bottom quartile in all 4 years for any given measure other than hospital-based utilization for CVD (1.1%). Conclusions and Relevance: A subset of physician groups that was consistently low performing could be identified by considering performance measures across multiple years. Considering the consistency of group performance could contribute a novel method to identify physician groups most likely to benefit from limited resources.

Drug Adherence and Long-Term Outcomes in Non-Revascularized Patients Following Acute Myocardial Infarction.

This study examined long-term outcomes and adherence to guideline-based medications in non-revascularized acute myocardial infarction (MI) patients undergoing and not undergoing angiography. We analyzed non-revascularized MI patients hospitalized in Alberta, Canada between 2010-2016 and categorized them according to whether they had undergone coronary angiography. Adherence to guideline-based medications was determined by the proportion of days covered (PDC) and subdivided into categories based on PDC: 0% (none), 1-40% (low), 40-79% (intermediate) and ≥ 80% (high). Patients not undergoing angiography were older, less frequently male, and had more comorbidities. Those not receiving angiography had higher rates of 2-year myocardial infarction (9.9% vs 6.1%, p <0.001), heart failure (14.9% vs 6.1%, p <0.001), and mortality (29.4% vs 7.4%, p <0.001). Optimal medial therapy (OMT), defined by high PDC for the combination of lipid-modifying agents, ß-blockers and angiotensin converting enzyme-inhibitors/receptor blockers (ACE-I/ARBs), was achieved in 32.9%. Patients not undergoing angiography had lower rates of OMT adherence (p <0.001). In patients not undergoing angiography, high-adherence to lipid-modifying agents (HR 0.70 [95% CI 0.57-0.87]), ß-blockers (HR 0.78 [0.62-0.97]), ACE-I/ARBs (HR 0.64 [0.52-0.79]) and OMT (HR 0.56 [0.40-0.77]) was independently associated with lower 2-year mortality. In conclusion, MI patients not receiving angiography had low adherence rates to guideline-based pharmacotherapies and high rates of long-term outcomes, suggesting potential treatment targets to improve prognosis in non-invasively managed MI patients.

Lipoprotein(a) is robustly associated with aortic valve calcium.

OBJECTIVES: To investigate the prevalence and quantity of aortic valve calcium (AVC) in two large cohorts, stratified according to age and lipoprotein(a) (Lp(a)), and to assess the association between Lp(a) and AVC. METHODS: We included 2412 participants from the population-based Rotterdam Study (52% women, mean age=69.6±6.3 years) and 859 apparently healthy individuals from the Amsterdam University Medical Centers (UMC) outpatient clinic (57% women, mean age=45.9±11.6 years). All individuals underwent blood sampling to determine Lp(a) concentration and non-enhanced cardiac CT to assess AVC. Logistic and linear regression analyses were performed to investigate the associations of Lp(a) with the presence and amount of AVC. RESULTS: The prevalence of AVC was 33.1% in the Rotterdam Study and 5.4% in the Amsterdam UMC cohort. Higher Lp(a) concentrations were independently associated with presence of AVC in both cohorts (OR per 50 mg/dL increase in Lp(a): 1.54 (95% CI 1.36 to 1.75) in the Rotterdam Study cohort and 2.02 (95% CI 1.19 to 3.44) in the Amsterdam UMC cohort). In the Rotterdam Study cohort, higher Lp(a) concentrations were also associated with increase in aortic valve Agatston score (ß 0.19, 95% CI 0.06 to 0.32 per 50 mg/dL increase). CONCLUSIONS: Lp(a) is robustly associated with presence of AVC in a wide age range of individuals. These results provide further rationale to assess the effect of Lp(a) lowering interventions in individuals with early AVC to prevent end-stage aortic valve stenosis.

Effect of icosapent ethyl on progression of coronary atherosclerosis in patients with elevated triglycerides on statin therapy: a prospective, placebo-controlled randomized trial (EVAPORATE): interim results.

AIMS: Though statin therapy is known to slow coronary atherosclerosis progression and reduce cardiovascular (CV) events, significant CV risk still remains. In the REDUCE-IT study, icosapent ethyl (IPE) added to statin therapy reduced initial CV events by 25% and total CV events by 30%, but its effects on coronary atherosclerosis progression have not yet been fully investigated. Therefore, this study is to determine whether IPE 4 g/day will result in a greater change from baseline in plaque volume measured by serial multidetector computed tomography than placebo in statin-treated patients. METHODS AND RESULTS: EVAPORATE is a randomized, double-blind, placebo-controlled trial. Patients had to have coronary atherosclerosis by coronary computed tomographic angiography (CCTA) (≥1 angiographic stenoses with ≥20% narrowing), on stable statin therapy with low-density lipoprotein cholesterol levels 40-115 mg/dL, and persistently high triglyceride levels (135-499 mg/dL). Patients underwent an interim scan at 9 months and were followed for an additional 9 months with CCTA at 0, 9, and 18 months. Here, we present the protocol-specified interim efficacy results. A total of 80 patients were enrolled, with 67 completing the 9-month visit and having interpretable CCTA at baseline and at 9 months (age = 57 ± 6 years, male = 36, 63%). At the 9-month interim analysis, there was no significant change in low attenuation plaque (LAP) between active and placebo groups (74% vs. 94%, P = 0.469). However, there was slowing of total non-calcified plaque (sum of LAP, fibrofatty, and fibrous plaque) (35% vs. 43%, P = 0.010), total plaque (non-calcified + calcified plaque) (15% vs. 26%, P = 0.0004), fibrous plaque (17% vs. 40%, P = 0.011), and calcified plaque (-1% vs. 9%, P = 0.001), after adjustment by baseline plaque, age, sex, diabetes, baseline triglyceride levels, and statin use. CONCLUSION: EVAPORATE is the first study using CCTA to evaluate the effects of IPE as an adjunct to statin therapy on atherosclerotic plaque characteristics in a high-risk CV population with persistently high triglyceride levels. It provides important mechanistic data in regards to the reduction in CV events in the REDUCE-IT clinical trial. CLINICALTRIALS. GOVIDENTIFIER: NCT029226027.

Cost-Effectiveness of Evolocumab Therapy for Myocardial Infarction: The Chinese Healthcare Perspective.

PURPOSE: Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are an indispensable lipid-lowering treatment option, but their cost-effectiveness has been questioned. This study aimed to perform a health economic evaluation of evolocumab versus placebo in patients with myocardial infarction (MI) in China. METHODS: A Markov cohort state-transition model was developed in decision analysis software to estimate the incremental cost-effectiveness ratio (ICER), defined as cost per quality-adjusted life-year (QALY) saved. The simulation subjects could undergo non-fatal MI and/or stroke, or vascular or non-vascular death event. We integrated the Chinese population-specific demographics and event rates with the risk reduction of evolocumab based on the FOURIER trial and/or lowering of low-density lipoprotein cholesterol (LDL-C). Age-related change, event costs and utilities were included from published sources. RESULTS: At its current list price [33,748 Chinese yuan (CNY) annually per person], the ICER for evolocumab therapy was 927,713 CNY per QALY gained when integrating the FOURIER trial with absolute reduction of LDL-C. The probability of cost-effectiveness of evolocumab versus placebo was 1.96%, with a generally accepted threshold of 212,676 CNY per QALY gained. A reduction in acquisition price by approximately 70% (to less than 10,255 CNY annually) was needed to be cost-effective. Alternative scenario analyses of therapeutic benefit showed that the ICER for evolocumab in MI patients with uncontrolled familial hypercholesterolemia (FH) was 187,736 CNY per QALY gained. CONCLUSION: Evolocumab in patients with MI was not cost-effective based on the price in 2019 in China; however, treatment with evolocumab was more favorable in MI patients with FH.

PURL: Consider this Rx for patients with high triglycerides?

A daily dose of this prescription fish oil may be worth a trial in light of the cardiovascular benefits it affords statin-treated patients with high triglycerides.

REDUCE-IT Eligibility and Preventable Cardiovascular Events in the US Population (from the National Health and Nutrition Examination Survey [NHANES]).

The reduction of cardiovascular events with icosapent ethyl-intervention (REDUCE-IT) trial showed in persons with prior cardiovascular disease (CVD) or diabetes mellitus (DM) that icosapent ethyl (IPE) reduced CVD events by 25%. We projected the preventable initial and total CVD events if REDUCE-IT trial eligibility criteria were applied to US adults. We identified US adults with available REDUCE-IT inclusion criteria from NHANES Surveys 1999-2016 and estimated primary (CVD death, nonfatal myocardial infarction, stroke, revascularization, or unstable angina) and secondary composite (CVD death, nonfatal MI or stroke) events using REDUCE-IT published event rates in the IPE and placebo groups, the difference being the number of preventable events. From 11,445 adults aged ≥45 years (representing 111.1 million [M]), a total of 319 persons (3.0 M) fit key REDUCE-IT eligibility criteria: triglycerides of 135 to 499 mg/dL, HbA1c <10%, blood pressure <200/100 mm Hg, and on a statin with LDL-C of 40 to 99 mg/dL. 63% had prior CVD and 37% had DM + ≥1 risk factor (primary prevention cohort). If these persons are given IPE for the REDUCE-IT median trial period of 4.9 years, we estimated preventing a total 349,817 (71,391/year) primary CVD outcomes of which 146,011 (29,798/year) were initial events. Most (24,151) preventable events were from the secondary prevention cohort. Using FDA eligibility criteria, an estimated 4.6 million persons would be eligible for IPE, with 60,544 preventable primary CVD outcomes annually from REDUCE-IT USA event rates. In conclusion, many CVD events in US adults with known CVD or DM and well-controlled LDL-C on statin therapy can be prevented with IPE.

Triglycerides and ASCVD Risk Reduction: Recent Insights and Future Directions.

PURPOSE OF REVIEW: This review focuses on recent evidence examining the role triglycerides (TG) and triglyceride-enriched lipoproteins (TGRL) play in atherosclerotic cardiovascular disease (ASCVD). It also provides a succinct overview of current and future TG-lowering therapies for ASCVD risk reduction. RECENT FINDINGS: Epidemiological and Mendelian randomization studies have consistently shown that TGRL are strongly associated with ASCVD. REDUCE-IT demonstrated cardiovascular benefit with icosapent ethyl in high-risk patients with hypertriglyceridemia on statin therapy. Polymorphisms in APOC3 and ANGPTL3 are associated with ASCVD and use of RNA-interfering therapies to target these proteins has shown TG lowering in early phase trials. TG and TGRL are causally associated with ASCVD. Lifestyle modifications and statin therapy can lower TG/TGRL and are considered first-line treatment for hypertriglyceridemia. Icosapent ethyl has been shown to reduce residual ASCVD risk in high-risk patients on maximally tolerated statins. Ongoing clinical trials will better define optimal therapy for patients on statins with residual hypertriglyceridemia.

Agonist of RORA Attenuates Nonalcoholic Fatty Liver Progression in Mice via Up-regulation of MicroRNA 122.

BACKGROUND & AIMS: Development of nonalcoholic steatohepatitis (NASH) is associated with reductions in hepatic microRNA122 (MIR122); the RAR related orphan receptor A (RORA) promotes expression of MIR122. Increasing expression of RORA in livers of mice increases expression of MIR122 and reduces lipotoxicity. We investigated the effects of a RORA agonist in mouse models of NASH. METHODS: We screened a chemical library to identify agonists of RORA and tested their effects on a human hepatocellular carcinoma cell line (Huh7). C57BL/6 mice were fed a chow or high-fat diet (HFD) for 4 weeks to induce fatty liver. Mice were given hydrodynamic tail vein injections of a MIR122 antagonist (antagomiR-122) or a control antagomiR once each week for 3 weeks while still on the HFD or chow diet, or intraperitoneal injections of the RORA agonist RS-2982 or vehicle, twice each week for 3 weeks. Livers, gonad white adipose, and skeletal muscle were collected and analyzed by reverse-transcription polymerase chain reaction, histology, and immunohistochemistry. A separate group of mice were fed an atherogenic diet, with or without injections of RS-2982 for 3 weeks; livers were analyzed by immunohistochemistry, and plasma was analyzed for levels of aminotransferases. We analyzed data from liver tissues from patients with NASH included in the RNA-sequencing databases GSE33814 and GSE89632. RESULTS: Injection of mice with antagomiR-122 significantly reduced levels of MIR122 in plasma, liver, and white adipose tissue; in mice on an HFD, antagomiR-122 injections increased fat droplets and total triglyceride content in liver and reduced ß-oxidation and energy expenditure, resulting in significantly more weight gain than in mice given the control microRNA. We identified RS-2982 as an agonist of RORA and found it to increase expression of MIR122 promoter activity in Huh7 cells. In mice fed an HFD or atherogenic diet, injections of RS-2982 increased hepatic levels of MIR122 precursors and reduced hepatic synthesis of triglycerides by reducing expression of biosynthesis enzymes. In these mice, RS-2982 significantly reduced hepatic lipotoxicity, reduced liver fibrosis, increased insulin resistance, and reduced body weight compared with mice injected with vehicle. Patients who underwent cardiovascular surgery had increased levels of plasma MIR122 compared to its levels before surgery; increased expression of plasma MIR122 was associated with increased levels of plasma free fatty acids and levels of RORA. CONCLUSIONS: We identified the compound RS-2982 as an agonist of RORA that increases expression of MIR122 in cell lines and livers of mice. Mice fed an HFD or atherogenic diet given injections of RS-2982 had reduced hepatic lipotoxicity, liver fibrosis, and body weight compared with mice given the vehicle. Agonists of RORA might be developed for treatment of NASH.

Catch of the Day: Icosapent Ethyl for Reducing Cardiovascular Risk.

For decades, omega-3 fatty acids (O3FA) have been used for their cardioprotective effects. Although several prescription products are available, icosapent ethyl (IPE) is the lone pure, eicosapentaenoic acid (EPA)-only, O3FA product. Initially approved by the Food and Drug Administration (FDA) to reduce triglyceride (TG) levels in patients with TG levels ≥500 mg/dL, the Reduction of Cardiovascular Events With Icosapent Ethyl-Intervention Trial (REDUCE-IT) demonstrated that IPE reduces cardiovascular events in patients with either established atherosclerotic cardiovascular disease (ASCVD) or diabetes plus ≥2 ASCVD risk factors, a TG level between 135 mg/dL and 499 mg/dL, and who were taking a statin. IPE is generally well tolerated, but caution is advised if used in patients taking antiplatelet or anticoagulant therapies because of an increased risk of bleeding. Based on the REDUCE-IT trial, the Food and Drug Administration granted IPE an indication for ASCVD risk reduction, making it the first O3FA product to receive such an indication. IPE is a cost-effective approach to reducing residual cardiovascular risk in high risk patients treated with statins.

Impact of omega-3 fatty acid oral therapy on healing of chronic venous leg ulcers in older adults: Study protocol for a randomized controlled single-center trial.

BACKGROUND: This trial addresses the global problem of chronic venous leg ulcers (CVLUs), wounds that cause significant infirmity for an estimated 9.7 million people annually, mainly older adults with comorbidities. Advanced therapies are needed because standard topical therapies are often ineffective or yield only short-term wound healing. Thus, we are testing a new oral therapy containing the bioactive elements of fish oil, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), for targeting and reducing the high numbers of activated polymorphonuclear leukocytes (PMN) in wound microenvironments that keep CVLUs "trapped" in a chronic inflammatory state. METHODS: This double-blind RCT will include 248 eligible adults ≥ 55 years of age with CVLUs receiving standard care at a large Midwest outpatient wound clinic. Participants are randomized to two groups: 12 weeks of daily oral therapy with EPA + DHA (1.87 g/day of EPA + 1.0 g/day of DHA) or daily oral therapy with placebo. At 0, 4, 8, and 12 weeks, across the two groups, we are pursuing three specific aims: Aim 1. Compare levels of EPA + DHA-derived lipid mediators, and inflammatory cytokines in blood and wound fluid; Subaim 1a. Compare inflammatory cytokine gene expression by PMNs in blood; Aim 2. Compare PMN activation in blood and wound fluid, and PMN-derived protease levels in wound fluid; Aim 3. Compare reduction in wound area, controlling for factors known to impact healing, and determine relationships with lipid mediators, cytokines, and PMN activation. Subaim 3a. Compare frequency of CVLU recurrence and levels of study variables in blood between the randomly assigned two subgroups (continuing EPA + DHA therapy versus placebo therapy beyond week 12) within the EPA + DHA group with healed CVLUs after 3 months of therapy. Subaim 3b. Compare symptoms of pain at all time points and quality of life at first and last time points across the two groups and two subgroups. DISCUSSION: This trial will provide new evidence about the effectiveness of EPA + DHA oral therapy to target and reduce excessive PMN activation systemically and locally in patients with CVLUs. If effective, this therapy may facilitate healing and thus be a new adjunct treatment for CVLUs in the aging population.

Treatments of nonalcoholic fatty liver disease in adults who have no other illness: A Review article.

Nonalcoholic fatty liver disease (NAFLD) is one of the most common liver diseases. In the absence of treatment, NAFLD can damage the liver tissue and even have extra-hepatic complications. No therapeutic regimen has ever been approved for the treatment of this disease. A variety of clinical trials have been conducted in the field of NAFLD. Reviewing these trials is necessary to provide the most effective treatments. In this article, we aimed to review randomized controlled trials that evaluate the effects of pharmacological agents on NAFLD adults without other illness.
