Pharmacokinetic/Pharmacodynamic Interactions Between Evogliptin and Glimepiride in Healthy Male Subjects.

ABSTRACT: Purpose: Evogliptin, a dipeptidyl peptidase-4 inhibitor, and glimepiride, a sulfonylurea, are used to treat type 2 diabetes mellitus. In this study, we aimed to evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) interactions between evogliptin and glimepiride.

Materials and methods: A randomized, open-label, 3-period, 3-treatment, 2-sequence crossover study was conducted in healthy male subjects. During each period, subjects received multiple doses of evogliptin 5 mg alone (EVO), glimepiride 4 mg alone (GLI), or a combination of the two (EVO+GLI). Serial blood and urine samples were collected 168 and 24 h post dosing, respectively, for PK and PD analyses.

Results: Thirty-four subjects completed the study. The co-administration of evogliptin and glimepiride did not alter their plasma and urine PK profiles. For evogliptin, the geometric mean ratio (GMR) (90% confidence intervals) for the maximum plasma concentrations at steady-state (C_max,ss) and the area under the curve during dosing interval at steady-state (AUC_?,ss) of EVO+GLI to E were 1.02 (0.98-1.06) and 0.97 (0.95-1.00), respectively. For glimepiride, the corresponding values of EVO+GLI to GLI were 1.08 (1.01-1.17) and 1.08 (1.02-1.14), respectively. All values were within the regulatory bioequivalence criteria of 0.8-1.25. Glucose excursion decreased with the co-administration of evogliptin and glimepiride compared with that observed with the evogliptin or glimepiride monotherapy.

Conclusion: Evogliptin and glimepiride had no PK interactions when co-administered, while the combination therapy showed an additive glucose-lowering effect compared to those of evogliptin or glimepiride monotherapy.

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.

Project description:PurposeHypertension and dyslipidemia are major risk factors for cardiovascular diseases, and reduction of cardiovascular risks can be achieved by combining antihypertensive therapy with statins. The objective of this study was to evaluate the pharmacokinetic interaction between telmisartan/amlodipine fixed dose combination and rosuvastatin in healthy Korean male volunteers.Patients and methodsAn open-label, two-cohort, multiple-dose, single-sequence crossover study was conducted in healthy male subjects. In Cohort 1, the subjects were administered one tablet of telmisartan/amlodipine 80 mg/5 mg once daily for 14 days with or without one tablet of rosuvastatin 20 mg once daily. In Cohort 2, the subjects were administered one tablet of rosuvastatin 20 mg once daily for 14 days with or without one tablet of telmisartan/amlodipine 80 mg/5 mg once daily. Serial blood samples were collected up to 24 hrs post-dose on the 9th and 14th days in Cohort 1 and on the 5th and 14th days in Cohort 2. Plasma drug concentrations were measured by liquid chromatography/tandem mass spectrometry. Pharmacokinetic parameters, including maximum plasma concentration at steady state (Cmax,ss) and area under the plasma concentration versus time curve over dosing interval (AUCτ,ss), were determined by non-compartmental analysis. The geometric least-square mean (GLSM) ratios and associated 90% confidence intervals (CIs) of log-transformed Cmax,ss and AUCτ,ss for separate or concurrent therapy were calculated to evaluate pharmacokinetic interactions.ResultsThirty-eight subjects from Cohort 1 and nineteen subjects from Cohort 2 completed the study. The GLSM ratios and 90% CIs of Cmax,ss and AUCτ,ss, were 0.9829 (0.8334-1.1590) and 1.0003 (0.9342-1.0710) for telmisartan; 0.9908 (0.9602-1.0223) and 1.0081 (0.9758-1.0413) for amlodipine; and 2.2762 (2.0113-2.5758) and 1.3261 (1.2385-1.4198) for rosuvastatin, respectively.ConclusionThe pharmacokinetic parameters of telmisartan/amlodipine, but not rosuvastatin, met the pharmacokinetic equivalent criteria. The increase in systemic exposure to rosuvastatin caused by telmisartan/amlodipine co-administration would not be clinically significant in practice. Nevertheless, an appropriately designed two-sequence crossover study is needed to confirm the results of this study.
