Effects of rosuvastatin, atorvastatin, simvastatin, and pravastatin on atherogenic dyslipidemia in patients with characteristics of the metabolic syndrome.

The metabolic syndrome (MS) is a constellation of coronary risk factors. Atherogenic dyslipidemia is an important factor in cardiovascular risk in these patients, and treatment of atherogenic dyslipidemia has been identified as an important goal of therapy in patients with MS. This post hoc analysis of data from a 6-week, randomized, open-label, parallel-group, comparative trial (Statin Therapies for Elevated Lipid Levels compared Across doses to Rosuvastatin [STELLAR]) assessed the effects of rosuvastatin 10, 20, and 40 mg, atorvastatin 10, 20, 40, and 80 mg, simvastatin 10, 20, 40, and 80 mg, and pravastatin 10, 20, and 40 mg on plasma lipids in hypercholesterolemic patients (low-density lipoprotein cholesterol >/=160 and <250 mg/dl; triglycerides <400 mg/dl) who had >/=3 of the 5 National Cholesterol Education Program Adult Treatment Panel III criteria for MS (body mass index >30 kg/m(2) substituted for waist circumference). Of 2,268 patients, 811 met criteria for MS. Percent reductions in low-density lipoprotein cholesterol ranged from 20% in the pravastatin 10-mg group to 55% in the rosuvastatin 40-mg group. In patients with MS, triglyceride reductions were 22% to 34% with rosuvastatin, 23% to 33% with atorvastatin, 15% to 23% with simvastatin, and 12% to 15% with pravastatin. High-density lipoprotein cholesterol increased by 8% to 11% with rosuvastatin, 5% to 9% with atorvastatin, 8% to 10% with simvastatin, and 3% to 7% with pravastatin. Rosuvastatin, atorvastatin, simvastatin, and pravastatin treatment had favorable effects in hypercholesterolemic patients on the atherogenic dyslipidemia associated with MS. Rosuvastatin had the most favorable effect on the atherogenic lipid profile of MS overall.

Effects of rosuvastatin versus atorvastatin, simvastatin, and pravastatin on non-high-density lipoprotein cholesterol, apolipoproteins, and lipid ratios in patients with hypercholesterolemia: additional results from the STELLAR trial.

BACKGROUND: Non-high-density lipoprotein cholesterol (HDL-C), apolipoprotein (apo) B, and lipid and apolipoprotein ratios that include both atherogenic and antiatherogenic lipid components have been found to be strong predictors of coronary heart disease risk. OBJECTIVE: The goal of this study was to examine prospectively the effects of rosuvastatin, atorvastatin, simvastatin, and pravastatin across dose ranges on non-HDL-C, apo B, apo A-I, and total cholesterol (TC):HDL-C, low-density lipoprotein cholesterol (LDL-C):HDL-C, non-HDL-C:HDL-C, and apo B:apo A-I ratios in patients with hypercholesterolemia (LDL-C > or =160 mg/dL and <250 mg/dL and triglycerides <400 mg/dL) in the Statin Therapies for Elevated Lipid Levels compared Across doses to Rosuvastatin (STELLAR) trial. METHODS: In this randomized, Multicenter, parallel-group, open-label trial (4522IL/0065), patients > or =18 years of age received rosuvastatin 10, 20, 40, or 80 mg; atorvastatin 10, 20, 40, or 80 mg; simvastatin 10, 20, 40, or 80 mg; or pravastatin 10, 20, or 40 mg for 6 weeks. Pairwise comparisons were prospectively planned and performed between rosuvastatin 10, 20, and 40 mg and milligram-equivalent or higher doses of comparators. RESULTS: A total of 2268 patients were randomized to the rosuvastatin 10- to 40-mg, atorvastatin, simvastatin, and pravastatin groups. Fifty-one percent of patients were women, the mean (SD) age was 57 (12) years, and 19% had a documented history of atherosclerotic disease. Over 6 weeks, rosuvastatin significantly reduced non-HDL-C, apo B, and all lipid and apolipoprotein ratios assessed, compared with milligram-equivalent doses of atorvastatin and milligram-equivalent or higher doses of simvastatin and pravastatin (all, P < 0.002). Rosuvastatin reduced non-HDL-C by 42.0% to 50.9% compared with 34.4% to 48.1% with atorvastatin, 26.0% to 41.8% with simvastatin, and 18.6% to 27.4% with pravastatin. Rosuvastatin reduced apo B by 36.7% to 45.3% compared with 29.4% to 42.9% with atorvastatin, 22.2% to 34.7% with simvastatin, and 14.7% to 23.0% with pravastatin. The highest increase in apo A-I (8.8%) was observed in the rosuvastatin 20-mg group, and this increase was significantly greater than in the atorvastatin 40-mg and 80-mg groups (both, P < 0.002). CONCLUSION: Rosuvastatin 10 to 40 mg was more efficacious in improving the lipid profile of patients with hypercholesterolemia than milligram-equivalent doses of atorvastatin and milligram-equivalent or higher doses of simvastatin and pravastatin.

Lipid-modifying effects of rosuvastatin in postmenopausal women with hypercholesterolemia who are receiving hormone replacement therapy.

OBJECTIVE: To evaluate the efficacy and safety of rosuvastatin in postmenopausal women with hypercholesterolemia who are receiving hormone replacement therapy (HRT) in a randomized, double-blind, placebo-controlled trial. METHODS: After a 6-week dietary lead-in period, 135 postmenopausal women who had been taking a stable HRT regimen for at least 3 months were randomized to receive rosuvastatin 5 mg, 10 mg or placebo for 12 weeks. Fasting levels of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), and triglycerides (TG) were assessed at weeks 0, 2, 6, 10, and 12; apolipoprotein (Apo) B and Apo A-I were measured at weeks 0 and 12. RESULTS: Rosuvastatin 5 mg and 10 mg significantly reduced LDL-C by 38% (SE = 2.1) and 49% (SE = 2.1), respectively, compared with placebo (1% [SE = 2.1]; p < 0.001). TC, TG, Apo B, and all lipid ratios examined (LDL-C/HDL-C, TC/HDL-C, non-HDL-C/HDL-C, and Apo B/Apo A-I) were also reduced significantly by both rosuvastatin doses (p < 0.001). HDL-C levels increased significantly in the rosuvastatin groups (11% and 8% for 5 mg and 10 mg, respectively, vs. -0.5% for placebo; p < 0.001), as did Apo A-I levels (p < 0.05). The combination of rosuvastatin plus HRT was well tolerated with no apparent differences among treatments in the numbers or types of adverse events reported. CONCLUSIONS: Rosuvastatin 5 mg or 10 mg once daily is a well-tolerated and highly efficacious lipid-lowering therapy in postmenopausal women receiving HRT.

Comparison of the efficacy and safety of rosuvastatin versus atorvastatin, simvastatin, and pravastatin across doses (STELLAR* Trial).

The primary objective of this 6-week, parallel-group, open-label, randomized, multicenter trial was to compare rosuvastatin with atorvastatin, pravastatin, and simvastatin across dose ranges for reduction of low-density lipoprotein (LDL) cholesterol. Secondary objectives included comparing rosuvastatin with comparators for other lipid modifications and achievement of National Cholesterol Education Program Adult Treatment Panel III and Joint European Task Force LDL cholesterol goals. After a dietary lead-in period, 2,431 adults with hypercholesterolemia (LDL cholesterol > or =160 and <250 mg/dl; triglycerides <400 mg/dl) were randomized to treatment with rosuvastatin 10, 20, 40, or 80 mg; atorvastatin 10, 20, 40, or 80 mg; simvastatin 10, 20, 40, or 80 mg; or pravastatin 10, 20, or 40 mg. At 6 weeks, across-dose analyses showed that rosuvastatin 10 to 80 mg reduced LDL cholesterol by a mean of 8.2% more than atorvastatin 10 to 80 mg, 26% more than pravastatin 10 to 40 mg, and 12% to 18% more than simvastatin 10 to 80 mg (all p <0.001). Mean percent changes in high-density lipoprotein cholesterol in the rosuvastatin groups were +7.7% to +9.6% compared with +2.1% to +6.8% in all other groups. Across dose ranges, rosuvastatin reduced total cholesterol significantly more (p <0.001) than all comparators and triglycerides significantly more (p <0.001) than simvastatin and pravastatin. Adult Treatment Panel III LDL cholesterol goals were achieved by 82% to 89% of patients treated with rosuvastatin 10 to 40 mg compared with 69% to 85% of patients treated with atorvastatin 10 to 80 mg; the European LDL cholesterol goal of <3.0 mmol/L was achieved by 79% to 92% in rosuvastatin groups compared with 52% to 81% in atorvastatin groups. Drug tolerability was similar across treatments.

Efficacy of rosuvastatin compared with other statins at selected starting doses in hypercholesterolemic patients and in special population groups.

A total of 5 randomized, double-blind trials in patients with hypercholesterolemia were prospectively designed to allow pooling of plasma lipid data after 12 weeks of treatment. The purpose was (1) to compare rosuvastatin 5 and 10 mg with atorvastatin 10 mg (data from 3 of the 5 trials); (2) to compare rosuvastatin 5 and 10 mg with simvastatin 20 mg and pravastatin 20 mg (data from 2 of the 5 trials); and (3) to summarize overall efficacy and subset analyses of rosuvastatin data from all 5 trials. Rosuvastatin 5 mg (n = 390) and 10 mg (n = 389) reduced low-density lipoprotein (LDL) cholesterol significantly more than did atorvastatin 10 mg (n = 393) (41.9% and 46.7% vs 36.4%, both p <0.001). Treatment with rosuvastatin 5 mg (n = 240) and 10 mg (n = 226) also resulted in significantly greater reductions in LDL cholesterol compared with both simvastatin 20 mg (n = 249) and pravastatin 20 mg (n = 252) (40.6% and 48.1% vs 27.1% and 35.7%, all p <0.001). Significant differences favoring rosuvastatin 10 mg were also observed for total cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL cholesterol, apolipoprotein (apo) B, and apo A-I versus atorvastatin 10 mg, and for total cholesterol, HDL cholesterol, triglycerides, non-HDL cholesterol, and apo B versus simvastatin 20 mg and pravastatin 20 mg. Analyses of all the rosuvastatin 10 mg data (n = 615) from the 5 trials in subgroups defined by age > or =65 years, female sex, postmenopausal status, hypertension, atherosclerosis, type 2 diabetes, and obesity showed that rosuvastatin had consistent efficacy across patient subgroups.

Efficacy of rosuvastatin 10 mg in patients with the metabolic syndrome.

The constellation of risk factors known as the metabolic syndrome increases the risk of coronary artery disease at any low-density lipoprotein (LDL) cholesterol level. We performed an exploratory analysis of data from 5 trials to study the effects of rosuvastatin 10 mg on lipid levels and ratios in hypercholesterolemic patients (LDL cholesterol > or =160 mg/dL and <250 mg/dL) who met a modified National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) definition of the metabolic syndrome. Of 580 patients completing 12 weeks of treatment with rosuvastatin 10 mg, 194 (33%) met the definition of the metabolic syndrome by exhibiting > or =3 of the following: body mass index >30; triglycerides > or =150 mg/dL; high-density lipoprotein (HDL) cholesterol <40 mg/dL in men and <50 mg/dL in women; blood pressure > or =130/> or =85 mm Hg or receiving current medication for hypertension; and fasting blood glucose > or =110 mg/dL. Patients with the metabolic syndrome had higher triglyceride, non-HDL cholesterol, apolipoprotein B, and lipid ratios, and lower HDL cholesterol and apolipoprotein A-I levels, at baseline compared with patients without the metabolic syndrome. In patients with the metabolic syndrome, rosuvastatin 10 mg improved LDL cholesterol (-47%), non-HDL cholesterol (-43%), non-HDL cholesterol/HDL cholesterol ratio (-47%), apolipoprotein B (-37%), apolipoprotein B/apolipoprotein A-I ratio (-40%), triglycerides (-23%), apolipoprotein A-I (+7%), and HDL cholesterol (+10%)-in a manner similar to that in hypercholesterolemic patients who did not meet these criteria. Among patients who met the metabolic syndrome criteria and who had triglycerides > or =200 mg/dL, 64% met their ATP III non-HDL goals.

Comparison of the efficacy of rosuvastatin versus atorvastatin, simvastatin, and pravastatin in achieving lipid goals: results from the STELLAR trial.

In the Statin Therapies for Elevated Lipid Levels compared Across doses to Rosuvastatin (STELLAR) trial, the efficacy of rosuvastatin calcium (Crestor) was compared with that of atorvastatin (Lipitor), simvastatin (Zocor), and pravastatin (Pravachol) for lowering plasma low-density lipoprotein cholesterol (LDL-C) after 6 weeks of treatment. In this multicenter, parallel-group, open-label trial, adults with hypercholesterolemia were randomized to treatments with rosuvastatin 10, 20, 40, or 80 mg, atorvastatin 10, 20, 40, or 80 mg, simvastatin 10, 20, 40, or 80 mg, or pravastatin 10, 20, or 40 mg. Efficacy and safety results from this trial have been previously published. The additional analyses included in this report show that 53% (83/156) to 80% (125/157) of patients in the rosuvastatin 10- to 40-mg groups achieved LDL-C levels < 100 mg/dl (< 2.6 mmol/l), compared with 18% (28/158) to 70% (115/165) of patients who received atorvastatin, 8% (13/165) to 53% (86/163) of patients who received simvastatin, and 1% (1/160) to 8% (13/161) of patients who received pravastatin. Other additional analyses showed that more patients in the rosuvastatin 10- to 40-mg groups than in the comparator groups who were at high risk of coronary heart disease according to National Cholesterol Education Program Adult Treatment Panel (ATP) III, Joint European Societies, or Canadian guidelines achieved the LDL-C goals of < 100 mg/dl (< 2.6 mmol/l) (55% to 77% compared with 0 to 64%), < 3.0 mmol/l (< 116 mg/dl) (76% to 94% compared with 6% to 81%), and < 2.5 mmol/l (< 97 mg/dl) (47% to 69% compared with 0 to 53%), respectively. Results favoring rosuvastatin versus the comparators were also reported for patients: (a) who had triglycerides > or = 200mg/dl (> or = 2.3 mmol/l), and achieved both ATP III LDL-C and non-high-density lipoprotein cholesterol (non-HDL-C) goals (80% to 84% versus 15% to 84%); (b) overall who achieved the Canadian LDL-C goals of < 2.5 (< 97 mg/dl) to < 5.0 mmol/l (< 193 mg/dl) (85% to 91% versus 44% to 86%); and (c) who achieved all 3 Canadian goals for LDL-C, triglycerides (< 3.0 mmol/l [< 266 mg/dl] to < 2.0 mmol/l [< 177 mg/dl]), and the total cholesterol/high-density lipoproteincholesterol ratio (< 4 to < 7) (70% to 83% versus 35% to 79%).
