Heterozygous familial hypercholesterolaemia is characterised by low cellular uptake of LDL cholesterol, increased plasma LDL cholesterol concentrations, and premature cardiovascular disease. Despite intensive statin therapy, with or without ezetimibe, many patients are unable to achieve recommended target levels of LDL cholesterol. We investigated the effect of PCSK9 inhibition with evolocumab (AMG 145) on LDL cholesterol in patients with this disorder. This multicentre, randomised, double-blind, placebo-controlled trial was undertaken at 39 sites (most of which were specialised lipid clinics, mainly attached to academic institutions) in Australia, Asia, Europe, New Zealand, North America, and South Africa between Feb 7 and Dec 19, 2013. 331 eligible patients (18–80 years of age), who met clinical criteria for heterozygous familial hypercholesterolaemia and were on stable lipid-lowering therapy for at least 4 weeks, with a fasting LDL cholesterol concentration of 2·6 mmol/L or higher, were randomly allocated in a 2:2:1:1 ratio to receive subcutaneous evolocumab 140 mg every 2 weeks, evolocumab 420 mg monthly, or subcutaneous placebo every 2 weeks or monthly for 12 weeks. Randomisation was computer generated by the study sponsor, implemented by a computerised voice interactive system, and stratified by LDL cholesterol concentration at screening (higher or lower than 4·1 mmol/L) and by baseline ezetimibe use (yes/no). Patients, study personnel, investigators, and Amgen study staff were masked to treatment assignments within dosing frequency groups. The coprimary endpoints were percentage change from baseline in LDL cholesterol at week 12 and at the mean of weeks 10 and 12, analysed by intention-to-treat. This trial is registered with ClinicalTrials.gov, number NCT01763918. Of 415 screened patients, 331 were eligible and were randomly assigned to the four treatment groups: evolocumab 140 mg every 2 weeks (n=111), evolocumab 420 mg monthly (n=110), placebo every 2 weeks (n=55), or placebo monthly (n=55). 329 patients received at least one dose of study drug. Compared with placebo, evolocumab at both dosing schedules led to a significant reduction in mean LDL cholesterol at week 12 (every-2-weeks dose: 59·2% reduction [95% CI 53·4–65·1], monthly dose: 61·3% reduction [53·6–69·0]; both p<0·0001) and at the mean of weeks 10 and 12 (60·2% reduction [95% CI 54·5–65·8] and 65·6% reduction [59·8–71·3]; both p<0·0001). Evolocumab was well tolerated, with rates of adverse events similar to placebo. The most common adverse events occurring more frequently in the evolocumab-treated patients than in the placebo groups were nasopharyngitis (in 19 patients [9%] vs five [5%] in the placebo group) and muscle-related adverse events (ten patients [5%] vs 1 [1%]). In patients with heterozygous familial hypercholesterolaemia, evolocumab administered either 140 mg every 2 weeks or 420 mg monthly was well tolerated and yielded similar and rapid 60% reductions in LDL cholesterol compared with placebo.

Elevated lipoprotein(a) is a genetic risk factor for cardiovascular disease in general population studies. However, its contribution to risk for cardiovascular events in patients with established cardiovascular disease or on statin therapy is uncertain. Patient-level data from seven randomised, placebo-controlled, statin outcomes trials were collated and harmonised to calculate hazard ratios (HRs) for cardiovascular events, defined as fatal or non-fatal coronary heart disease, stroke, or revascularisation procedures. HRs for cardiovascular events were estimated within each trial across predefined lipoprotein(a) groups (15 to <30 mg/dL, 30 to <50 mg/dL, and ≥50 mg/dL, vs <15 mg/dL), before pooling estimates using multivariate random-effects meta-analysis. Analyses included data for 29 069 patients with repeat lipoprotein(a) measurements (mean age 62 years [SD 8]; 8064 [28%] women; 5751 events during 95 576 person-years at risk). Initiation of statin therapy reduced LDL cholesterol (mean change −39% [95% CI −43 to −35]) without a significant change in lipoprotein(a). Associations of baseline and on-statin treatment lipoprotein(a) with cardiovascular disease risk were approximately linear, with increased risk at lipoprotein(a) values of 30 mg/dL or greater for baseline lipoprotein(a) and 50 mg/dL or greater for on-statin lipoprotein(a). For baseline lipoprotein(a), HRs adjusted for age and sex (vs <15 mg/dL) were 1·04 (95% CI 0·91–1·18) for 15 mg/dL to less than 30 mg/dL, 1·11 (1·00–1·22) for 30 mg/dL to less than 50 mg/dL, and 1·31 (1·08–1·58) for 50 mg/dL or higher; respective HRs for on-statin lipoprotein(a) were 0·94 (0·81–1·10), 1·06 (0·94–1·21), and 1·43 (1·15–1·76). HRs were almost identical after further adjustment for previous cardiovascular disease, diabetes, smoking, systolic blood pressure, LDL cholesterol, and HDL cholesterol. The association of on-statin lipoprotein(a) with cardiovascular disease risk was stronger than for on-placebo lipoprotein(a) (interaction p=0·010) and was more pronounced at younger ages (interaction p=0·008) without effect-modification by any other patient-level or study-level characteristics. In this individual-patient data meta-analysis of statin-treated patients, elevated baseline and on-statin lipoprotein(a) showed an independent approximately linear relation with cardiovascular disease risk. This study provides a rationale for testing the lipoprotein(a) lowering hypothesis in cardiovascular disease outcomes trials. Novartis Pharma AG.

Despite contemporary therapies for acute coronary syndrome (ACS), morbidity and mortality remain high. Low levels of high-density lipoprotein (HDL) cholesterol are common among patients with ACS and may contribute to ongoing risk. Strategies that raise levels of HDL cholesterol, such as inhibition of cholesterol ester transfer protein (CETP), might reduce risk after ACS. Dal-OUTCOMES is a multicenter, randomized, double-blind, placebo-controlled trial designed to test the hypothesis that CETP inhibition with dalcetrapib reduces cardiovascular morbidity and mortality in patients with recent ACS. The study will randomize approximately 15,600 patients to receive daily doses of dalcetrapib 600 mg or matching placebo, beginning 4 to 12 weeks after an index ACS event. There are no prespecified boundaries for HDL cholesterol levels at entry. Other elements of care, including management of low-density lipoprotein cholesterol, are to follow best evidence-based practice. The primary efficacy measure is time to first occurrence of coronary heart disease death, nonfatal acute myocardial infarction, unstable angina requiring hospital admission, resuscitated cardiac arrest, or atherothrombotic stroke. The trial will continue until 1,600 primary end point events have occurred, all evaluable subjects have been followed for at least 2 years, and 80% of evaluable subjects have been followed for at least 2.5 years. Dal-OUTCOMES will determine whether CETP inhibition with dalcetrapib, added to current evidence-based care, reduces cardiovascular morbidity and mortality after ACS.

Dalcetrapib, an inhibitor of cholesteryl ester transfer protein, raises HDL cholesterol levels. In this clinical trial involving patients with an acute coronary syndrome, dalcetrapib had no beneficial effect on clinical outcomes, despite raising HDL cholesterol levels. High-density lipoproteins (HDLs) participate in the process of cellular cholesterol efflux and may have additional protective effects against atherothrombosis. 1 An inverse association between levels of HDL cholesterol and incident events of coronary heart disease has been shown in observational studies 2 , 3 and persists in most post hoc analyses and meta-analyses of trials of statin therapy for patients with cardiovascular risk factors, chronic cardiovascular disease, or recent acute coronary syndrome. 4 – 10 However, it remains uncertain whether pharmacologic intervention that raises HDL cholesterol levels results in decreased cardiovascular risk. 11 – 16 Moreover, changes in HDL cholesterol levels may not reflect changes in the . . .

Effect of fluvastatin on renal end points in the Assessment of Lescol in Renal Transplant (ALERT) trial. Hyperlipidemia is a risk factor for long-term renal transplant dysfunction, but no prospective clinical trials have investigated the effects of statin treatment on graft function in renal transplant recipients. The aim of the present study was to evaluate the effect of fluvastatin on long-term renal transplant function and development of chronic allograft nephropathy in the ALERT (Assessment of Lescol in Renal Transplantation) study. ALERT was a randomized, double-blind, placebo-controlled study of the effect of fluvastatin, 40 mg and 80 mg daily, in renal transplant recipients. Patients were randomized to receive either fluvastatin (N = 1050) or placebo (N = 1052) and followed for five to six years. Renal end points included graft loss or doubling of serum creatinine or death; glomerular filtration rate (GFR) was also measured during follow-up in a subset of patients (N = 439). There were 283 patients (13.5%) with graft loss, mainly due to chronic rejection (82%), yielding an annual rate of 2.4%. Fluvastatin treatment significantly lowered mean low-density lipoprotein (LDL)-cholesterol levels by 32% (95% CI -33 to -30) compared with placebo, but had no significant effect on the incidence of renal graft loss or doubling of serum creatinine, or decline in GFR throughout follow-up in the whole study population. Neither was any treatment effect by fluvastatin found in any of the subgroups analyzed. Fluvastatin treatment significantly improves lipid values in renal transplant recipients but has no effect on graft loss or doubling of serum creatinine.

This randomized, placebo-controlled, double-blind, multicenter trial assessed the safety and efficacy of the thyromimetic compound eprotirome in lowering the serum low-density lipoprotein cholesterol level in patients with hypercholesterolemia who were already receiving simvastatin or atorvastatin. Eprotirome was associated with decreased LDL levels in patients treated with statins. Eprotirome, a thyromimetic compound, was associated with decreased LDL levels in patients treated with statins. The association between elevated levels of circulating low-density lipoprotein (LDL) cholesterol and an increased risk of atherosclerotic cardiovascular disease is well established, 1 as are the reductions in both levels of serum cholesterol and the risk of cardiovascular disease that occur with the use of inhibitors of hepatic 3-hydroxy-3-methyl-glutaryl coenzyme A reductase. 1 However, the efficacy of statins is limited if stringent goals for serum LDL cholesterol levels are not achieved 2 in patients receiving statins alone 3 or if side effects develop that require a dose reduction or discontinuation of the agent. 4 Furthermore, statins are less effective in lowering levels of other lipoproteins, . . .

Extended-release niacin (ERN) improves multiple lipid parameters but is underused owing to niacin-induced flushing (NIF). Laropiprant (LRPT) reduces NIF; however, its effects on chronic flushing (>6 months) have not been studied. We examined whether after 20 weeks of treatment with ERN/LRPT, patients who continued ERN/LRPT would experience less NIF than patients who stopped LRPT and continued ERN alone. A total of 1,152 dyslipidemic patients were randomized 2:2:1 to group 1, ERN/LRPT 1 g/20 mg/day from 0 to 4 weeks and then ERN/LRPT 2 g/40 mg/day from 5 to 32 weeks; group 2, ERN/LRPT 1 g/20 mg/day from 0 to 4 weeks, ERN/LRPT 2 g/40 mg/day from 5 to 20 weeks, and then ERN 2 g/day without LRPT from 21 to 32 weeks; or group 3, placebo for the entire study. The end points included the number of days each week with a moderate or greater Global Flushing Severity Score (GFSS) ≥4 (primary end point) and the percentage of patients with a maximum GFSS of ≥4 (secondary end point) during the postwithdrawal period (weeks 21 to 32). ERN/LRPT produced significantly less NIF than ERN alone during the postwithdrawal period, as measured by the number of days each week with a GFSS of ≥4 (p <0.001) and the percentage of patients with a maximum GFSS of ≥4 (p <0.001; ERN/LRPT 19.6%; ERN 48.9%; placebo 9.2%). Compared with ERN alone, ERN/LRPT produced fewer drug-related adverse experiences during the postwithdrawal period. After 20 weeks of stable maintenance therapy, dyslipidemic patients treated continuously with ERN/LRPT experienced less NIF than did patients who had had LRPT withdrawn and had continued with ERN alone. In conclusion, the results of our study support the long-term efficacy of ERN/LRPT in reducing NIF symptoms.

High-density lipoprotein cholesterol (HDL-C) concentration is inversely related to risk of major adverse cardiovascular events (MACE) in epidemiologic studies but is a poorer predictor of MACE in patients with established coronary heart disease. HDL particle concentration (HDLP) has been proposed as a better predictor of risk. We investigated whether HDLP is associated with risk of MACE after acute coronary syndrome (ACS). The dal-Outcomes trial compared the CETP inhibitor dalcetrapib with placebo in patients with recent ACS. In a nested case-cohort analysis, total, large, medium, and small HDLPs were measured by nuclear magnetic resonance spectroscopy at baseline (4-12 weeks after ACS) in 476 cases with MACE and 902 controls. Hazard ratios (HRs; case-control) for 1-SD increment of HDLP or HDL-C at baseline were calculated with and without adjustment for demographic, clinical, laboratory, and treatment variables. Similarly, HRs for MACE were calculated for changes in HDLP or HDL-C from baseline to month 3 of assigned treatment. Over median follow-up of 28 months, the risk of MACE was not associated with baseline HDLP (adjusted HR = 0.98, 95% CI = 0.84-1.15, P = .81), any HDLP subclass, or HDL-C. Dalcetrapib increased HDL-C and total, medium, and large HDLP and decreased small HDLP but had no effect on MACE compared with placebo. There were no association of risk of MACE with change in HDLP or HDL-C and no interaction with assigned study treatment. Neither baseline HDLP nor the change in HDLP on treatment with dalcetrapib or placebo was associated with risk of MACE after ACS.

Renal transplant recipients are at increased risk of premature cardiovascular disease. Although statins reduce cardiovascular risk in the general population, their efficacy and safety in renal transplant recipients have not been established. We investigated the effects of fluvastatin on cardiac and renal endpoints in this population. We did a multicentre, randomised, double-blind, placebo-controlled trial in 2102 renal transplant recipients with total cholesterol 4·0–9·0 mmol/L. We randomly assigned patients fluvastatin (n=1050) or placebo (n=1052) and follow up was for 5–6 years. The primary endpoint was the occurrence of a major adverse cardiac event, defined as cardiac death, non-fatal myocardial infarction (MI), or coronary intervention procedure. Secondary endpoints were individual cardiac events, combined cardiac death or non-fatal MI, cerebrovascular events, non-cardiovascular death, all-cause mortality, and graft loss or doubling of serum creatinine. Analysis was by intention to treat. After a mean follow-up of 5·1 years, fluvastatin lowered LDL cholesterol concentrations by 32%. Risk reduction with fluvastatin for the primary endpoint (risk ratio 0·83 [95% Cl 0·64-1·06], p=0·139) was not significant, although there were fewer cardiac deaths or non-fatal Ml (70 vs 104, 0·65 [0·48–0·88] p=0·005) in the fluvastatin group than in the placebo group. Coronary intervention procedures and other secondary endpoints did not differ significantly between groups. Although cardiac deaths and non-fatal Ml seemed to be reduced, fluvastatin did not generally reduce rates of coronary intervention procedures or mortality. Overall effects of fluvastatin were similar to those of statins in other populations. Published online June 3, 2003 http://image.thelancet.com/extras/03art4377web.pdf

Self-rated health (SRH) is a strong predictor for disease and death. The relations among SRH, psychosocial factors, and cortisol dynamics were tested using pooled data from the LiVicordia study of 50-year-old men in Lithuania (n = 94) and Sweden (n = 89), controlling for effect of residence. SRH was assessed by \"How would you assess your own health?\" A standardized laboratory stress test included measures of cortisol in serum and saliva. Good SRH related to high scale scores of decision latitude, social support at work, coping, self-esteem, and sense of coherence; to low scores of overcommitment (all p < .01) and vital exhaustion (r = -0.40, p < 0.001); to low concentrations of saliva baseline cortisol (r = -.26, p = .001); and to a strong cortisol response to stress (r = .27, p = .001). Findings that good SRH related to favorable psychosocial characteristics and to a dynamic cortisol stress response indicate a possible explanation for observed lower risk for disease and death in this state.
