Ezetimibe in hypercholesterolaemia.

Ezetimibe is the first member of a new class of selective cholesterol absorption inhibitors, compounds that effectively block intestinal absorption of dietary and biliary cholesterol, without affecting absorption of fat soluble vitamins or triglycerides. Ezetimibe underwent glucuronidation to a single metabolite and localised at the intestinal wall, where it prevented luminal cholesterol absorption. Pre-clinical studies demonstrated the lipid-lowering and antiatherosclerotic properties of ezetimibe. The efficacy and safety of ezetimibe monotherapy have been determined in phase II/III studies: in phase II studies, the optimal efficacy was reached with ezetimibe 10 mg per day and the pooled efficacy data have shown that ezetimibe 10 mg has a positive effect on the lipoprotein profile with a significant reduction in LDL-cholesterol of 18.5%, an increase in HDL-cholesterol of 3.5% and a trend towards lowering in triglyceride concentrations (-4.9%). The monotherapy phase III studies have confirmed the efficacy with a decrease in LDL-C of 17.4% and have demonstrated an excellent safety and tolerability profile. The potential for a pharmacokinetic and/or pharmacodynamic interaction between ezetimibe and various statins and the efficacy and safety or the co-administration of ezetimibe and statins have been evaluated in different phase I/II studies: ezetimibe had no significant effect on the pharmacokinetics of simvastatin or atorvastatin. Ezetimibe 10 mg co-administrated with the starting dose of any statin induced a mean 18% additive LDL-C lowering effect. This additive 18% reduction in LDL-C is achieved in one step compared with the three steps necessary with statin monotherapy.

Diabetes: statins, fibrates, or both?

Cardiovascular disease is the leading cause of mortality in patients with type 2 diabetes. Among the many factors that are involved in the pathogenesis of atherosclerosis in diabetic patients, dyslipidemia plays a major role. It is characterized by an increase in triglycerides, a decrease in high-density lipoprotein cholesterol and normal or mildly elevated low-density lipoprotein cholesterol. The management of patients with diabetic dyslipidemia is difficult because we lack studies specifically designed for diabetic patients. Thus, strategy has to rely on post hoc analyses of landmark intervention trials, which usually include only a small number of diabetic patients, or on rare trials enrolling small cohorts of diabetic patients. When lifestyle changes fail, monotherapy should be tried first with either a statin or a fibrate, depending on triglyceride level. If lipid target values are not reached, a combination therapy can then be initiated, with close follow-up of potential side effects.

Effects of statins on biomarkers of bone metabolism: a randomised trial.

BACKGROUND AND AIM: Recently, several studies have indicated there may be differences among statins regarding a possible association between therapy and a reduction in risk of fractures. No data from prospective randomised clinical trials designed to assess either biochemical or clinical effects on bone metabolism are yet available. We assayed levels of biochemical markers of bone formation in stored serum samples from a recently completed randomised clinical trial conducted to compare the effects of simvastatin and atorvastatin on the lipid profile of patients with hypercholesterolaemia. METHODS AND RESULTS: This 12-week, randomised, multicenter, open-label study was designed to compare the safety and lipid-lowering efficacy of simvastatin 40 mg or 80 mg with that of atorvastatin 20 mg or 40 mg in 846 hypercholesterolaemic patients. Stored serum samples from this study were analysed to compare the effects of simvastatin and atorvastatin on 2 biomarkers of bone turnover, bone-specific alkaline phosphatase (BSAP), a marker of bone formation, and C-teleopeptide of type 1 collagen (CTx), a marker of bone resorption. Treatment with simvastatin 40 and 80 mg/day, but not atorvastatin 20 and 40 mg/day, led to significant (p < 0.05) reductions in BSAP in both men (4.1-5.4% reduction) and women (4.2-7.4% reduction). In addition, there appeared to be a dose-dependent effect with greater reductions in BSAP seen with the 80 mg dose of simvastatin. Treatment with either 20 mg or 40 mg of atorvastatin had no significant effect on BSAP levels on the groups as a whole or in the gender-specific subgroups. CTx showed a small, but not statistically significant, decrease with simvastatin, again with an apparent dose-related trend. Atorvastatin treatment generally resulted in small, non significant increases in CTx. CONCLUSIONS: The present serum bone biomarker results show that treatment with simvastatin, but not atorvastatin, decreases BSAP and suggest that simvastatin may have a beneficial effect on bone turnover.

[Management of dyslipidemias diagnosed in general practice in France--The PRAGMA Study].

Several studies have reported the penetration and impact of national and international recommendations on the management of dyslipidaemia, a major cardiovascular risk factor. Most of them were carried out on patients participating in clinical trials or on in-hospital cases. The PRAGMA study was developed in order to evaluate management of this condition in general practice, at the heart of the health care system. From September to December 1998, 1,717 general practitioners were chosen randomly and included 6,623 patients considered to have a lipid disorder. In this sample, the prevalence of the main risk factors was as follows: hypertension: 39.6%, diabetes: 11.6%, obesity: 19.6%, past or present smokers: 33.8%. The main lines of management consisted in prescribing lipid lowering drugs (96.6%) with dietary recommendations (95.8%) and a fall lipid profile (59.9%). The main factors spontaneously cited by the general practitioners as being decisional were: the total cholesterol level (47.8%), diet (40.8%), body weight (29.4%) and drug therapy (19.2%). The cardiovascular risk factors were rarely taken into account in their totality. These results suggest that the management of dyslipidaemia patients by general practitioners is far from being optimal. Efforts should be made to change attitudes to take into consideration the global cardiovascular risk factors of patients with lipid disorders.

[Obesity and cardiovascular risk].

Overweight and obesity are recognised as responsible for an increase in vascular risk and in excess mortality due to cardio-vascular diseases. This is especially true in presence of increased visceral (central) fat distribution, a key factor for insulin-resistance, the main component of the metabolic syndrome X. Cardio-vascular risk in overweight and obese subjects appears strongly correlated with the common risk factors, more frequently present in these patients: type 2 diabetes, hypertension, lipid abnormalities. Weight reduction improves all risk factors and decreases the patient's global vascular risk. The improvement in the various risk factors is significant with a moderate weight loss (10% of the initial weight). Weight reduction should been obtained always with nutritional-hygienic means (physical activity, weight-reducing diet...) maintained for several months. Only when these approaches appear to be insufficient, the need for an associated pharmacological treatment has to be considered. Amongst the weight-reducing drugs currently available or close to be, orlistat has demonstrated its interest in the glycemic control of type 2 diabetic patients, and its favourable effect in hypertensive patients. Available clinical studies have clearly shown the more marked effect of orlistat in comparison to placebo in reducing the various risk factors. So far, few studies have been conducted to assess the effects of the specific drug therapy on the control of metabolic abnormalities and risk factors in overweight or obese patients, except in type 2 diabetic patients for whom, most of the oral anti-diabetic agents have been tested in overweight or obese diabetic population.

Effect of combined fluvastatin-fenofibrate therapy compared with fenofibrate monotherapy in severe primary hypercholesterolemia. French Fluvastatin Study Group.

This double-blind study was designed to assess the efficacy and safety of fluvastatin-fenofibrate combination therapy compared with fenofibrate monotherapy in severe primary hypercholesterolemia (low-density lipoprotein [LDL] cholesterol > or =190 mg/dl [4.9 mmol/L], triglycerides < or =350mg/dl [3.9 mmol/l]). After a 10-week placebo and dietary baseline period, 102 patients were randomized to receive micronized fenofibrate 200 mg, fluvastatin 20 mg plus micronized fenofibrate 200 mg, or fluvastatin 40 mg plus micronized fenofibrate 200 mg. At week 16, fenofibrate 200 mg alone lowered LDL cholesterol from baseline by 21% compared with 32% for fluvastatin 20 mg plus fenofibrate 200 mg and 41% for fluvastatin 40 mg plus fenofibrate 200 mg (p <0.001). Triglycerides decreased by 29% with fenofibrate 200 mg alone, 39% with fluvastatin 20 mg plus fenofibrate 200 mg, and 40% with fluvastatin 40 mg plus fenofibrate 200 mg (p <0.05). Safety was assessed by recording adverse events and measuring clinical laboratory parameters. The adverse event profile was similar for the 3 treatment groups. One patient withdrew due to an increase in transaminase levels. No significant increase in creatine phosphokinase levels was observed with combination therapy. In conclusion, the addition of fluvastatin to micronized fenofibrate results in substantial improvement in atherogenic plasma lipids and is well tolerated.

Autosomal dominant type IIa hypercholesterolemia: evaluation of the respective contributions of LDLR and APOB gene defects as well as a third major group of defects.

Autosomal dominant type IIa hypercholesterolaemia (ADH) is characterised by an elevation of total plasma cholesterol associated with increased LDL particles. Numerous different molecular defects have been identified in the LDL receptor (LDLR) and few specific mutations in the apolipoprotein B (APOB) gene resulting in familial hypercholesterolaemia and familial defective apoB-100 respectively. To estimate the respective contribution of LDLR, APOB and other gene defects in this disease, we studied 33 well characterised French families diagnosed over at least three generations with ADH through the candidate gene approach. An estimation of the proportions performed with the HOMOG3R program showed that an LDLR gene defect was involved in approximately 50% of the families (P = 0.001). On the other hand, the estimated contribution of an APOB gene defect was only 15%. This low estimation of ADH due to an APOB gene defect is further strengthened by the existence of only two probands carrying the APOB (R3500Q) mutation in the sample. More importantly and surprisingly, 35% of the families in the sample were estimated to be linked to neither LDLR nor APOB genes. These data were confirmed by the exclusion of both genes through direct haplotyping in three families. Our results demonstrate that the relative contributions of LDLR and APOB gene defects to the disease are very different. Furthermore, our results also show that genetic heterogeneity is, generally, underestimated in ADH, and that at least three major groups of defects are involved. At this point, the contribution of the recently mapped FH3 gene to ADH cannot be assessed nor its importance in the group of 'non LDLR/non APOB' families.

Action of atorvastatin in combined hyperlipidemia : preferential reduction of cholesteryl ester transfer from HDL to VLDL1 particles.

Combined hyperlipidemia (CHL) is characterized by a concomitant elevation of plasma levels of triglyceride-rich, very low density lipoproteins (VLDLs) and cholesterol-rich, low density lipoproteins (LDLs). The predominance of small, dense LDLs contributes significantly to the premature development of coronary artery disease in patients with this atherogenic dyslipoproteinemia. In the present study, we evaluated the impact of atorvastatin, a newly developed inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMGCoA) reductase, on the cholesteryl ester transfer protein (CETP)-mediated remodeling of apolipoprotein (apo) B-containing lipoprotein subspecies, and more specifically, the particle subpopulations of VLDL and LDL in CHL. In parallel, we evaluated the atorvastatin-induced modulation of the quantitative and qualitative features of atherogenic apo B-containing and cardioprotective apo AI-containing lipoprotein subspecies. Atorvastatin therapy (10 mg/d for a 6-week period) in patients with a lipid phenotype typical of CHL (n=18) induced reductions of 31% (P<0.0001) and 36% (P<0.0001) in plasma total cholesterol and LDL cholesterol, respectively. In addition, atorvastatin significantly reduced VLDL cholesterol, triglycerides, and apo B levels by 43% (P<0.0001), 27% (P=0.0006), and 31% (P<0.0001), respectively. The plasma concentrations of triglyceride-rich lipoproteins (VLDL1, Sf 60 to 400; VLDL2, Sf 20 to 60; and intermediate density lipoproteins, Sf 12 to 20) and of LDL, as determined by chemical analysis, were markedly diminished after drug therapy (-30% and -28%, respectively; P<0.0007). Atorvastatin significantly reduced circulating levels of all major LDL subspecies, ie, light (-28%, P<0.0008), intermediate (-27%, P<0.0008), and dense (-32%, P<0.0008) LDL; moreover, in terms of absolute lipoprotein mass, the reduction in dense LDL levels (mean -62 mg/dL) was preponderant. In addition, the reduction in plasma dense LDL concentration after therapy was significantly correlated with a reduction in plasma VLDL1 levels (r=0.429, P=0.0218). Atorvastatin induced a significant reduction (-7%, P=0.0039) in total CETP-dependent CET activity, which accurately reflects a reduction in plasma CETP mass concentration. Total CETP-mediated CET from high density lipoproteins to apo B-containing lipoproteins was significantly reduced (-26%, P<0.0001) with drug therapy. Furthermore, CETP activity was significantly correlated with the atorvastatin-induced reduction in plasma VLDL1 levels (r=0.456, P=0. 0138). Indeed, atorvastatin significantly and preferentially decreased CET from HDL to the VLDL1 subfraction (-37%, P=0.0064), thereby reducing both the levels (-37%, P=0.0001) and the CE content (-20%, P<0.005) of VLDL1. We interpret our data to indicate that 2 independent but complementary mechanisms may be operative in the atorvastatin-induced reduction of atherogenic LDL levels in CHL: first, a significant degree of normalization of both the circulating levels and the quality of their key precursors, ie, VLDL1, and second, enhanced catabolism of the major LDL particle subclasses (ie, light, intermediate, and dense LDL) due to upregulation of hepatic LDL receptors.

Efficacy of atorvastatin compared with simvastatin in patients with hypercholesterolemia.

BACKGROUND: Atorvastatin, a new enantiomerically pure synthetic statin, has shown a marked low-density lipoprotein (LDL) cholesterol reduction at doses ranging from 10 to 80 mg/d. This trial was designed to compare the efficacy of atorvastatin 10 mg with simvastatin 10 mg and 20 mg, the latter dose being commonly used in some countries. METHODS AND RESULTS: A parallel group, randomized, PROBE, multicenter study was conducted to compare the efficacy of 10 mg/d atorvastatin with that of 10 mg/d simvastatin and 20 mg/d simvastatin in patients with primary hypercholesterolemia. After a 6-week diet-placebo lead-in period, 272 patients with LDL cholesterol > or = 160 mg/dL and triglycerides < or = 300 mg/dL were randomized to 6 weeks of treatment with atorvastatin 10 mg (109 patients), simvastatin 20 mg (109 patients), or simvastatin 10 mg (54 patients). In the main analysis, which tested the equivalence of atorvastatin 10 mg and simvastatin 20 mg, the mean percent change in LDL cholesterol for atorvastatin 10 mg (-37.0%) was greater than and not equivalent to simvastatin 20 mg (-33.8%). In the secondary analysis, which compared the efficacy of atorvastatin 10 mg with that of simvastatin 10 mg, the mean decrease in LDL cholesterol was significantly greater (P < .001) for atorvastatin 10 mg than for simvastatin 10 mg (-37.0% vs. -28.9%). The two drugs were well tolerated, with an incidence of clinical and biochemical side effects similar among the 3 treatment groups. CONCLUSION: In primary hypercholesterolemia, atorvastatin 10 mg was more effective and nonequivalent to simvastatin 20 mg and significantly more effective than simvastatin 10 mg for reducing LDL cholesterol levels.

Efficacy and safety of micronised fenofibrate in a randomised double-blind study comparing four doses from 200 mg to 400 mg daily with placebo in patients with hypercholesterolemia.

The aim of this study was to evaluate the efficacy on LDL-cholesterol (LDL-C) of micronised fenofibrate given for three months at doses ranging from 200 to 400 mg once daily, compared with placebo. A double-blind, randomised, parallel-group, multi-centre trial was performed in four centers of France in 340 hypercholesterolemic patients (163M, 177F) aged 18-75 years. After a 2-3 month single-blind run-in period on placebo and diet, patients with LDL-C greater than or equal to 4.65 mmol/l (180 mg/dl) maintained on the same diet throughout the study were randomly allocated to placebo or to 200, 267, 340 or 400 mg micronised fenofibrate, given once daily with the evening meal for 3 months. LDL-C, total cholesterol (TC), total triglycerides (TG) and apolipoprotein B (Apo B) significantly decreased compared with placebo in all four fenofibrate groups. For all randomised patients, the decrease in the fenofibrate groups ranged from 31.6-38.8% for LDL-C, 24.5-31.9% for TC, 26.7-40.8% for TG, and 27.3-35.0% for Apo B. An increase in HDL-cholesterol of 4.1-8.2% was observed in the fenofibrate groups, but did not reach statistical significance. Lipid values in the placebo group remained unchanged. The therapeutic goal of LDL-C<3.36 mmol/l (130 mg/dl) was reached in 27% in the 200 mg group and increased to 56% in the 300 mg group. There were no major clinical or biological adverse events in the dose interval from 200 mg to 400 mg of micronised fenofibrate per day. This study showed treatment for 3 months with micronised fenofibrate at doses up to 400 mg per day is effective and can reduce LDL-cholesterol up to 30% allowing further evaluation of these doses on longer trials.

[The hyperlipidemias. Role of various statins].

MECHANISM OF ACTION: Statins act by competitive inhibition of HMG-CoA reductase, a key enzyme regulating cholesterol synthesis. Reduction in serum LDL, the crucial biological expression dependent on this mechanism, varies in intensity as a function of the type and of the dose of statin. PLEIOTROPIC EFFECTS: Besides their lipid lowering effect, statins have also been demonstrated to have pleiotropic effects mostly directly related to HMG-CoA reductase inhibition. CARDIOVASCULAR IMPACT: Several clinical studies investigating prevention of cardiovascular disease have established that statins decrease cardiovascular morbidity and mortality. Results have been very coherent for both primary and secondary prevention with statins. The cardiovascular benefit is most likely partly related to its pleiotropic effects, particularly those inducing a stabilization of the atheromatous plaques. INDICATIONS: Interventional studies have clearly established the role of statins in comparison with other lipid lowering agents for the prevention of cardiovascular events in most situations although a few therapeutic choices remain a subject of debate. Globally, the primary indications of statins are hypercholesterolemia and mixed hyperlipidemia with moderately elevated triglycerides. There are still some questions concerning the therapeutic goals of statin therapy.

Plasma lipoprotein distribution and lipid transfer activities in patients with type IIb hyperlipidemia treated with simvastatin.

The aim of the present study was to search in type IIb hyperlipidemic patients for putative concomitant effects of simvastatin on the physicochemical characteristics of low density lipoproteins (LDL) and high density lipoproteins (HDL), as well as on the activities of the cholesteryl ester transfer protein (CETP) and the phospholipid transfer protein (PLTP) that were determined in both endogenous lipoprotein-dependent and endogenous lipoprotein-independent assays. In a double-blind, randomized trial, patients received either placebo (one tablet/day; n = 12) or simvastatin (20 mg/day; n = 12) for a period of 8 weeks after a 5-week run-in period. Simvastatin, unlike placebo, reduced the lipid and apolipoprotein B contents of the most abundant LDL-1, LDL-2, and LDL-3 subfractions without inducing significant changes in the overall size distribution of LDL and HDL. Whereas simvastatin significantly increased PLTP activity in an endogenous lipoprotein-dependent assay (P < 0.01), no variation was observed in a lipoprotein-independent assay. Simvastatin significantly decreased plasma CETP activity in an endogenous lipoprotein-dependent assay (P < 0.01), and the reduction in plasma cholesteryl ester transfer rates was explained by a 16% drop in CETP mass concentration (P < 0.01). In contrast, the specific activity of CETP was unaffected by the simvastatin treatment reflecting at least in part the lack of significant alteration in plasma triglyceride-rich lipoprotein acceptors. The simvastatin-induced changes in plasma CETP mass levels correlated positively with changes in plasma CETP activity (r = 0.483, P = 0.0561), in total cholesterol levels (r = 0.769; P < 0.01), and in LDL-cholesterol levels (r = 0.736; P < 0.01). Whereas the observations suggest that simvastatin might exert concomitant beneficial effects on plasma CETP and LDL levels, neither plasma cholesteryl ester transfer activity nor plasma phospholipid transfer activity appeared as the main determinants of the LDL and HDL distribution profiles in type IIb hyperlipidemic patients.

A third major locus for autosomal dominant hypercholesterolemia maps to 1p34.1-p32.

Autosomal dominant hypercholesterolemia (ADH), one of the most frequent hereditary disorders, is characterized by an isolated elevation of LDL particles that leads to premature mortality from cardiovascular complications. It is generally assumed that mutations in the LDLR and APOB genes account for ADH. We identified one large French pedigree (HC2) and 12 additional white families with ADH in which we excluded linkage to the LDLR and APOB, implicating a new locus we named "FH3." A LOD score of 3.13 at a recombination fraction of 0 was obtained at markers D1S2892 and D1S2722. We localized the FH3 locus to a 9-cM interval at 1p34.1-p32. We tested four regional markers in another set of 12 ADH families. Positive LOD scores were obtained in three pedigrees, whereas linkage was excluded in the others. Heterogeneity tests indicated linkage to FH3 in approximately 27% of these non-LDLR/non-APOB ADH families and implied a fourth locus. Radiation hybrid mapping located four candidate genes at 1p34.1-p32, outside the critical region, showing no identity with FH3. Our results show that ADH is genetically more heterogeneous than conventionally accepted.

Mass concentration of plasma phospholipid transfer protein in normolipidemic, type IIa hyperlipidemic, type IIb hyperlipidemic, and non-insulin-dependent diabetic subjects as measured by a specific ELISA.

Mean plasma phospholipid transfer protein (PLTP) concentrations were measured for the first time by using a competitive enzyme-linked immunosorbent assay. PLTP mass levels and phospholipid transfer activity values, which were significantly correlated among normolipidemic plasma samples (r=0.787, P<0.0001), did not differ between normolipidemic subjects (3.95+/-1.04 mg/L and 575+/-81 nmol. mL-1. h-1, respectively; n=30), type IIa hyperlipidemic patients (4. 06+/-0.84 mg/L and 571+/-43 nmol. mL-1. h-1, respectively; n=36), and type IIb hyperlipidemic patients (3.90+/-0.79 mg/L and 575+/-48 nmol. mL-1. h-1, respectively; n=33). No significant correlations with plasma lipid parameters were observed among the various study groups. In contrast, plasma concentrations of the related cholesteryl ester transfer protein (CETP) were higher in type IIa and type IIb patients than in normolipidemic controls, and significant, positive correlations with total and low density lipoprotein cholesterol levels were noted. Interestingly, plasma PLTP mass concentration and plasma phospholipid transfer activity were significantly higher in patients with non-insulin-dependent diabetes mellitus (n=50) than in normolipidemic controls (6.76+/-1. 93 versus 3.95+/-1.04 mg/L, P<0.0001; and 685+/-75 versus 575+/-81 nmol. mL-1. h-1, P<0.0001, respectively). In contrast, CETP levels did not differ significantly between the 2 groups. Among non-insulin-dependent diabetes mellitus patients, PLTP levels were positively correlated with fasting glycemia and glycohemoglobin levels (r=0.341, P=0.0220; and r=0.382, P=0.0097, respectively) but not with plasma lipid parameters. It is proposed that plasma PLTP mass levels are related to glucose metabolism rather than to lipid metabolism.

Current and future treatment of hyperlipidemia: the role of statins.

Hyperlipidemia is recognized as one of the major risk factors for the development of coronary artery disease and progression of atherosclerotic lesions. Dietary therapy together with hypolipidemic drugs are central to the management of hyperlipidemia, which aims to prevent atherosclerotic plaque progression, induce regression, and so decrease the risk of acute coronary events in patients with pre-existing coronary or peripheral vascular disease. In patients at high risk of coronary artery disease but without evidence of atherosclerosis, treatment is designed to prevent the premature development of coronary artery disease, whereas in those with hypertriglyceridemia, treatment aims to prevent the development of hepatomegaly, splenomegaly, and pancreatitis. The 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, or statins, are the most potent lipid-lowering agents currently available, and their use in the treatment of hyperlipidemia provides the focus for this review. Particular emphasis is given to cerivastatin, a new HMG-CoA reductase inhibitor that combines potent cholesterol-lowering properties with significant triglyceride-reducing effects. Recently completed primary and secondary intervention trials have shown that the significant reductions in low-density lipoprotein (LDL) cholesterol achieved with statins result in significant reductions in morbidity and mortality associated with coronary artery disease as well as reductions in the incidence of stroke and total mortality. Such benefits occur early in the course of statin therapy and have led to suggestions that these drugs may possess antiatherogenic effects over and above their capacity to lower atherogenic lipids and lipoproteins. Experimental studies have also shown statin-induced improvements in endothelial function, decreased platelet thrombus formation, improvements in fibrinolytic activity, and reductions in the frequency of transient myocardial ischemia.

Cerivastatin in the treatment of mixed hyperlipidemia: the RIGHT study. The Cerivastatin Study Group. Cerivastatin Gemfibrozil Hyperlipidemia Treatment.

The Cerivastatin Gemfibrozil Hyperlipidemia Treatment (RIGHT) study--a multicenter, randomized, double-blind, placebo-controlled study--compared the lipid-lowering effects of cerivastatin, once daily at doses of 0.1, 0.2, and 0.3 mg with those of twice-daily gemfibrozil 600 mg in 751 patients with primary mixed hyperlipidemia. Randomization to the first 16 weeks of treatment followed an initial 4-week washout period and subsequent 6-week diet-controlled, placebo run-in phase. Patients continued to receive study medication for a further 36 weeks, with those previously on placebo switched to 0.1 mg/day cerivastatin at the end of week 16. Additional cholestyramine therapy was permitted at week 36 in patients with uncontrolled low-density lipoprotein (LDL) cholesterol levels. Cerivastatin achieved significant dose-dependent reductions in LDL cholesterol of 15-24% after 16 weeks of treatment, compared with reductions of 7.5% with gemfibrozil. Over this period both cerivastatin (0.3 mg) and gemfibrozil (1,200 mg) significantly decreased levels of triglycerides (20.3% vs 50.3%, respectively) and very low-density lipoprotein (VLDL) cholesterol (30.8% vs 47.1%, respectively), as well as increasing high-density lipoprotein (HDL) cholesterol (11.3% vs 13.3%, respectively). The reductions in LDL cholesterol and other atherogenic lipids and lipoproteins at 16 weeks were sustained in the subsequent 36-week double-blind continuation phase, during which time <10% of patients received additional cholestyramine therapy. Both study drugs were well tolerated, with the incidence of adverse events similar to that of placebo treatment. Clinically significant increases in hepatic transaminases and creatine phosphokinase occurred at a similar low frequency of around 1%. This study demonstrated that cerivastatin is a safe, well-tolerated, and effective treatment for lowering elevated LDL cholesterol and triglycerides in patients with mixed hyperlipidemia.
