Efficacy and Tolerability of a Fixed-Dose Combination of Rosuvastatin and Ezetimibe Compared with a Fixed-Dose Combination of Simvastatin and Ezetimibe in Brazilian Patients with Primary Hypercholesterolemia or Mixed Dyslipidemia: A Multicenter, Randomized Trial.

ABSTRACT: BACKGROUND:The addition of ezetimibe to statin therapy has been reported to result in increased efficacy for reduction of LDL-C levels and achievement of lipid targets, compared with monotherapy. OBJECTIVE:This study was designed to demonstrate the noninferiority of therapy with fixed-dose rosuvastatin plus ezetimibe formulations versus fixed dose simvastatin and ezetimibe formulations for reduction of LDL-C levels in Brazilian patients with hypercholesterolemia or mixed dyslipidemia. METHODS:Phase III, multicenter, randomized, parallel, open-label, noninferiority study that included male and female participants (aged 21-80 years) with hypercholesterolemia or mixed dyslipidemia. After a 1-week screening period with washout of lipid-lowering medications when needed, patients were treated with simvastatin 20 mg/d for 5 weeks. Participants with LDL-C levels ?100 mg/dL after the initial treatment were submitted to a 1-week washout period, and then randomized 1:1 to receive either combined rosuvastatin 10 mg?+?ezetimibe 10 mg (R/E) or simvastatin 20 mg?+?ezetimibe 10 mg (S/E) for 4 weeks and, if they still did not achieve the stipulated target, doses were readjusted to rosuvastatin 20 mg?+?ezetimibe 10 mg or simvastatin 40 mg?+?ezetimibe 10 mg, respectively, for 4 weeks. RESULTS:One hundred twenty-nine participants were enrolled, including 66 in R/E and 63 in S/E. At the end of simvastatin 20 mg treatment period, mean LDL-C values were 124.79 mg/dL and 121.27 mg/dL for participants randomized to R/E and S/E arms, respectively. After 4 weeks of R/E 10 mg?+?10 mg or S/E 20 mg?+?10 mg combined treatments, adjusted mean LDL-C values were 74.21 mg/dL and 85.58 mg/dL, respectively (P?=?0.0005), and after 9 weeks, with dose adjustment to R/E 20 mg?+?10 mg in 6 patients and to S/E 40 mg +10 mg in 19 patients, LDL-C adjusted mean values were 75.29 mg/dL and 86.62 mg/dL, respectively (P?=?0.0006). There was a statistically significant difference between the association R/E and S/E (P?=?0.0013) in percentage change of LDL-C after 9 weeks of combined treatments. The adjusted mean difference was estimated at -10.32% (95% CI, -16.94% to -3.70%). The LDL-C <100 mg/dL target was achieved in a significantly greater proportion of participants at week 4 in the R/E compared with the S/E arm (84.8% vs 68.2%; P?=?.0257), and at week 9, the proportion was 81.2% versus 73.0%, respectively (P?=?0.23). LDL-C <70 mg/dL was achieved at a significantly greater proportion in the R/E arm, both at week 4 (45.4% vs 15.9%; P?=?0.003) and week 9 (40.9% vs 15.9%; P?=?0.0017). A statistically significant difference at week 9 (P?=?0.0106) was observed in fasting blood glucose in the R/E arm, but the overall incidence of adverse events was not significantly different between groups. CONCLUSIONS:Rosuvastatin and ezetimibe fixed dose combination in both 10 mg/10 mg and 20 mg/10 mg doses, respectively, provided significantly lower levels of LDL-C compared with simvastatin and ezetimibe in doses of 20 mg/10 mg and 40 mg/10 mg, respectively. The fixed-dose combinations were both effective and well tolerated in this Brazilian study population. ClinicalTrials.gov identifier: NCT01420549. (Curr Ther Res Clin Exp. 2020; 81:XXX-XXX).

Project description:Statins are the frontline in cholesterol reduction therapies; however, their use in combination with agents that possess complimentary mechanisms of action may achieve further reductions in low-density lipoprotein cholesterol. Thirty-nine patients were treated with either 80 mg simvastatin (n=20) or 10 mg simvastatin plus 10 mg ezetimibe (n=19) for 6 weeks. Dosing was designed to produce comparable low-density lipoprotein cholesterol reductions, while enabling assessment of potential simvastatin-associated pleiotropic effects. Baseline and post-treatment plasma were analyzed for lipid mediators (eg, eicosanoids and endocannabinoids) and structural lipids by liquid chromatography tandem mass spectrometry. After statistical analysis and orthogonal projections to latent structures multivariate modeling, no changes were observed in lipid mediator levels, whereas global structural lipids were reduced in response to both monotherapy (R(2)Y=0.74; Q(2)=0.66; cross-validated ANOVA P=7.0×10(-8)) and combination therapy (R(2)Y=0.67; Q(2)=0.54; cross-validated ANOVA P=2.6×10(-5)). Orthogonal projections to latent structures modeling identified a subset of 12 lipids that classified the 2 treatment groups after 6 weeks (R(2)Y=0.65; Q(2)=0.61; cross-validated ANOVA P=5.4×10(-8)). Decreases in the lipid species phosphatidylcholine (15:0/18:2) and hexosyl-ceramide (d18:1/24:0) were the strongest discriminators of low-density lipoprotein cholesterol reductions for both treatment groups (q<0.00005), whereas phosphatidylethanolamine (36:3e) contributed most to distinguishing treatment groups (q=0.017). Shifts in lipid composition were similar for high-dose simvastatin and simvastatin/ezetimibe combination therapy, but the magnitude of the reduction was linked to simvastatin dosage. Simvastatin therapy did not affect circulating levels of lipid mediators, suggesting that pleiotropic effects are not associated with eicosanoid production. Only high-dose simvastatin reduced the relative proportion of sphingomyelin and ceramide to phosphatidylcholine (q=0.008), suggesting a pleiotropic effect previously associated with a reduced risk of cardiovascular disease.

Project description:AimsThe aim of this study was to evaluate the low-density lipoprotein cholesterol lowering efficacy and safety of a bempedoic acid 180 mg and ezetimibe 10 mg fixed-dose combination in patients with hypercholesterolemia and a high risk of cardiovascular disease receiving maximally tolerated statin therapy.MethodsThis phase 3, double-blind clinical trial enrolled adult patients at high risk of cardiovascular disease due to atherosclerotic cardiovascular disease, heterozygous familial hypercholesterolemia, or multiple cardiovascular disease risk factors. Patients were randomly assigned (2:2:2:1) to treatment with the fixed-dose combination, bempedoic acid 180 mg, ezetimibe 10 mg or placebo added to stable background statin therapy for 12 weeks. The primary efficacy endpoint was the percentage change from baseline to week 12 in low-density lipoprotein cholesterol.ResultsAmong the 301 patients included in the primary analysis, the mean baseline low-density lipoprotein cholesterol level was 3.87 mmol/L (149.8 mg/dL). At week 12, the fixed-dose combination lowered low-density lipoprotein cholesterol (-36.2%) significantly more than placebo (1.8% (placebo-corrected difference -38.0%); P < 0.001), ezetimibe alone (-23.2%; P < 0.001) or bempedoic acid alone (-17.2%; P < 0.001). The fixed-dose combination lowered low-density lipoprotein cholesterol levels similarly across subgroups, including patients receiving high-intensity, other-intensity or no statin therapy. Improvements with the fixed-dose combination were also observed in secondary efficacy endpoints, including high-sensitivity C-reactive protein. In this trial, fixed-dose combination treatment had a generally similar safety profile compared with bempedoic acid, ezetimibe or placebo.ConclusionThe bempedoic acid and ezetimibe fixed-dose combination significantly lowered low-density lipoprotein cholesterol versus placebo or other oral monotherapies and had a favourable safety profile when added to maximally tolerated statin therapy in patients with hypercholesterolemia and high cardiovascular disease risk.Trial registrationClinicalTrials.gov identifier: NCT03337308.

Project description:The purpose of this study was to compare the efficacy and tolerability of combination therapy of ezetimibe and atorvastatin in patients with high LDL cholesterol that had not reached the lipid management target value with 10 mg atorvastatin monotherapy, against increasing the dose to 20 mg atorvastatin or switching to 2.5 mg rosuvastatin.This was an open-label, randomized, multicenter, 3-parallel-group comparison trial at 23 community hospitals and clinics in Japan (enrollment period March 2009 to May 2010) in 125 patients with high LDL cholesterol.A total of 125 Japanese patients with high LDL cholesterol level were randomized to 1 of the following 3 treatment groups: the ezetimibe (10 mg/d) and atorvastatin (10 mg/d) group, the atorvastatin (20 mg/d) group, or the rosuvastatin (2.5 mg/d) group for 12 weeks after treatment with 10 mg atorvastatin alone for 4 weeks.Percent change in LDL cholesterol level from baseline (4 weeks after treatment with 10 mg atorvastatin alone) until study completion.The percent change in LDL cholesterol level from baseline until study completion was statistically greater for the combination of 10 mg ezetimibe + 10 mg atorvastatin compared with increasing atorvastatin to 20 mg (-25.8% vs -15.1%; P < 0.0001). A similar result was observed for ezetimibe + atorvastatin compared with switching to 2.5 mgt rosuvastatin (-25.8% vs 0.8%; P < 0.0001). The proportion of patients who reached the target LDL cholesterol value with the combination of ezetimibe + atorvastatin was significantly higher than increasing atorvastatin and switching to rosuvastatin (78.7%, 41.3%, and 3.1%, respectively). Although 5 serious adverse experiences bearing no relation to the study medications were reported, there were no adverse reactions.The combination of 10 mg ezetimibe +10 mg atorvastatin was more effective than increasing atorvastatin to 20 mg or switching to 2.5 mg rosuvastatin in patients with hypercholesterolemia whose LDL cholesterol levels had not reached the recommended target value with 10 mg atorvastatin monotherapy for 4 weeks. Ezetimibe coadministration with atorvastatin was well tolerated. ClinicalTrials.gov identifier: NCT00871351.

Project description:Highlights • In patients with T2DM and hypercholesterolemia untreated with lipid-lowering drugs:• BA + EZE FDC lowered LDL-C levels by 38.8% at week 12• BA + EZE FDC significantly reduced LDL-C and non-HDL-C vs ezetimibe or placebo• BA + EZE FDC significantly reduced hsCRP vs ezetimibe or placebo• BA + EZE FDC was safe and generally well tolerated Objective Statins are sometimes associated with worsened glycemic control. Patients with type 2 diabetes mellitus (T2DM) may require non-statin therapies to achieve low-density lipoprotein cholesterol (LDL-C) lowering goals. This study evaluated the efficacy and safety of bempedoic acid 180 mg plus ezetimibe 10 mg fixed-dose combination (BA + EZE FDC) in patients with T2DM and hypercholesterolemia who were not receiving background statins or other lipid-lowering therapy. Methods Patients with T2DM and elevated LDL-C levels were enrolled into this phase 2, double-blind study (NCT03531905). Patients received placebo during a 5-week washout period where background lipid-lowering therapies (including statins) were discontinued. Eligible patients were then randomized 1:1:1 to receive either BA + EZE FDC, ezetimibe 10 mg, or placebo once daily for 12 weeks. Assessments included the percent change from baseline to week 12 in LDL-C, other lipid parameters, and high-sensitivity C-reactive protein (hsCRP); and the monitoring of safety and tolerability. Results Among 179 randomized patients, baseline characteristics following the washout period were similar across treatment groups, with mean LDL-C levels of 142.6 mg/dL and mean glycated hemoglobin of 8.0%. At week 12, BA + EZE FDC therapy lowered mean LDL-C levels by 38.8%, significantly more than ezetimibe alone (19.2%; difference, 19.5% [95% confidence interval (CI), 13.4%–25.7%]; p < 0.001) or placebo (increase of 0.9%; difference, 39.6% [95% CI, 33.4%–45.8%]; p < 0.001). BA + EZE FDC significantly reduced hsCRP levels from baseline vs ezetimibe (29.2%; p = 0.005) and vs placebo (36.7%; p < 0.001). Incidence of treatment-emergent adverse events was low in all treatment groups, with no indication of worsened glycemic control. Conclusion In patients with T2DM and hypercholesterolemia who were not receiving statins or other lipid-lowering drugs, BA + EZE FDC significantly lowered LDL-C levels and was generally well tolerated.
