The Bioequivalence and Effect of Food on the Pharmacokinetics of a Fixed-Dose Combination Tablet Containing Rosuvastatin and Ezetimibe in Healthy Japanese Subjects.

ABSTRACT: Certain patient populations are unable to achieve the recommended low-density lipoprotein cholesterol goals with statin monotherapy alone. Such patients may benefit from concomitant therapy with ezetimibe (EZE) 10 mg added on to a statin. To this end, fixed-dose combination (FDC) tablets containing EZE 10 mg and rosuvastatin (ROS) 2.5 mg (EZE/ROS2.5) and EZE 10 mg and ROS 5 mg (EZE/ROS5) have been developed for treatment of hypercholesterolemia. The purpose of the series of clinical studies reported herein was to evaluate the potential food effect (MK-0653H, protocol 836 (P836)) and the bioequivalence between FDC and co-administration of EZE and ROS in healthy Japanese subjects under fasted and fed conditions (MK-0653H, protocol 835 (P835) and MK-0653H, protocol 846 (P846), respectively). These studies show there is no clinically relevant food effect on EZE exposure following single oral administration of the FDC EZE/ROS5 in healthy Japanese subjects; however, ROS exposure was decreased in the fed state under conditions used to evaluate the maximum food effect. Following single oral administration of individual ROS tablets under the same conditions, the magnitude of decrease in ROS exposure was comparable to that seen with FDC, suggesting that the effect of food on ROS exposure was similar between the FDC tablet and co-administration of individual EZE and ROS tablets. The FDC EZE/ROS5 was generally well tolerated in healthy Japanese subjects under fasted and fed conditions.

Project description:BackgroundEzetimibe is a new class of antihyperlipidemic agent indicated for the prevention of atherosclerosis disease and for the treatment of hypercholesterolemia. Information on the pharmacokinetic profiles of ezetimibe tablet in healthy Chinese volunteers are lacking, and regulatory requirements necessitate a bioequivalence study of ezetimibe tablet versus Ezetrol® in China.MethodsA single-dose randomized, open-label, two-group, two-period crossover study was conducted in 59 healthy Chinese volunteers under fasting or fed conditions to assess the bioequivalence between two preparations. Eligible participants were randomly divided into fasted and fed groups. Blood samples were collected at specified time intervals, and the plasma concentrations of ezetimibe and ezetimibe glucuronide were determined by a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. PK and bioavailability parameters were estimated via non-compartmental methods. Adverse events were also recorded.ResultsFifty-nine healthy volunteers were enrolled in the study. The main pharmacokinetic parameters of total ezetimibe in the plasma of the ezetimibe tablet (10 mg) and the Ezetrol® (10 mg) after a single fasting administration: Cmax were (65.73 ± 47.14), (71.32 ± 51.98) ng·mL- 1; Tmax were 1.75, 1.25 h; T½ were (17.09 ± 13.22), (17.35 ± 12.14) h; AUC0-t were (643.34 ± 400.77), (668.49 ± 439.57) h·ng·mL- 1; AUC0-∞ were (706.36 ± 410.92), (734.23 ± 468.26) h·ng·mL- 1. The main pharmacokinetic parameters of total ezetimibe in plasma of ezetimibe tablet (10 mg) and Ezetrol® (10 mg) after a fed administration: Cmax were (83.38 ± 38.95), (84.74 ± 34.62) ng·mL- 1; Tmax were 2.50, 2.50 h; T½ were (22.56 ± 12.68), (19.80 ± 15.59) h; AUC0-t were (494.21 ± 208.65), (536.69 ± 209.11) h·ng·mL- 1; AUC0-∞ were (573.74 ± 252.74), (604.75 ± 247.13) h·ng·mL- 1. The main pharmacokinetic parameters Cmax, AUC0-t, and AUC0-∞ of the two drugs were analyzed by variance analysis after logarithmic transformation. The total ezetimibe under fasting state with 90% confidence intervals (CIs) were 85.29 ~ 97.19, 90.41% ~ 104.38%, and 90.81 ~ 106.05%; total ezetimibe in fed state were 86.36% ~ 109.17, 84.96% ~ 96.40, and 85.32% ~ 101.0%. The 90% CIs of the ratio of geometric means (GMRs) of Cmax, AUC0-t, and AUC0-∞ of Ezetrol® and ezetimibe tablet both fasting and fed conditions fell within the conventional bioequivalence criteria of 0.80-1.25. Both Cmax and AUC met the predetermined criteria for assuming bioequivalence. No severe adverse events were observed.ConclusionsThe test ezetimibe tablet and Ezetrol® were determined to be bioequivalent under both fasting and fed conditions in Chinese people.Trial registrationClinicaltrials, NCT05681247 (retrospectively registered in 11/01/ 2023).

Project description:The aim of the study was to determine the various pharmacokinetic parameters of the newly developed cost-effective aceclofenac 100 mg tablet formulation (F-15) and to establish the bioequivalence against the marketed brand (ACEMED). Both products (test and reference) were given to 12 healthy non-smokers male subjects with overnight fasting of >10hr. The study was a randomized, single-dose, open-label, two sequence, and two treatment crossover design, with a washout period of 2 weeks. Blood samples (5 mL) from the human subjects were collected before (0 hr) and after drug administration at 13different time points (0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 12 and 18 hrs). The drug plasma concentration was analyzed by a validated RP-HPLC method using a solvent system containing acetonitrile and deionized water (60:40% v/v). Linearity was found to be 0.999 over the drug concentration range of 50μg/mL to 0.05μg/mL with LLOQ and LOD of 0.05μg/mL and 0.025μg/mL respectively. Non-compartmental pharmacokinetic analysis was performed using Kinetica® (ver. 5.1) software. Using the log-transformed data Cmax, AUC0-t, AUC0-∞, AUMCtot, and MRT were calculated. The Cmax of the test and brand was found to be 8.629±1.251μg/mL and 8.478±0.913μg/mL. The AUC0-t and AUC0-∞ of the test and the reference were computed to be 20.890 ±2.2021μg/mL.h, 23.272 ±1.914 μg/mL.h and 19.850 ±2.911 μg/mL.h, 22.890 ± 2.110 μg/mL.h correspondingly. Two-way analysis of variance (ANOVA) test and two one-sided t-test (p>0.05; non-significant) were applied to assess the variation in the period, sequence, subjects, and treatment. Geometric mean ratios for above mentioned pharmacokinetic parameters of reference/test were found within the acceptable FDA limits of 80-125% using 90% CI. There was no inter and intrasubject variation (p> 0.05) that was observed. Therefore, the directly compressible aceclofenac (100 mg) test formulation and the commercial reference tablets were declared to be biosimilar.

Project description:BackgroundThe 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.ObjectiveThis 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.MethodsPhase 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.ResultsOne 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.ConclusionsRosuvastatin 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:Background and objectiveRosuvastatin and ezetimibe are commonly applied in lipid-lowering pharmacotherapy. However, the pharmacokinetic (PK) interaction was not clear by the coadministration of rosuvastatin and ezetimibe. This study investigated the pharmacodynamic (PD) and PK interactions between rosuvastatin and ezetimibe through a crossover clinical trial.Subjects and methodsA randomized, open-label, multiple-dose, two-treatment, two-period, two-sequence crossover study with two treatment parts was conducted in healthy male subjects. Study part A involved rosuvastatin, and study part B involved ezetimibe. A total of 25 subjects in both parts completed the PK and PD evaluations. Rosuvastatin (20 mg) or ezetimibe (10 mg) was administered once daily for 7 days as monotherapy or co-therapy. The plasma concentrations of rosuvastatin, total ezetimibe and free ezetimibe were measured for 72 h after day 7. Low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and total cholesterol (TC) were investigated for the PD assessments on day 1 (pretreatment) and day 8.ResultsRosuvastatin and ezetimibe presented multiple peaks. The 90% confidence intervals (CIs) of the geometric mean ratios for the peak plasma concentration at steady state (Cmax,ss) and area under the plasma concentration-time curve during the dosing interval at steady state (AUCτ,ss) of rosuvastatin and total ezetimibe were within the range 0.8-1.25. However, the coadministration increased the systemic exposure of free ezetimibe. In the PD assessments, rosuvastatin and ezetimibe monotherapy reduced the LDL-C and TC levels effectively. In addition, the lipid-lowering effects of the coadministration corresponded to an approximate summation of the effects of rosuvastatin and ezetimibe monotherapy. However, no significant changes in HDL-C were observed with rosuvastatin or ezetimibe treatment. No significant safety issue was noted.ConclusionThe coadministration of rosuvastatin and ezetimibe revealed a bioequivalent PK interaction. Additional lipid-lowering effects, including decreased LDL-C and TC, were observed as expected in combination therapy without significant safety concern.
