Absolute Bioavailability of Esaxerenone and Food Effects on its Pharmacokinetics After a Single Oral Dose in Healthy Japanese Subjects: An Open-Label Crossover Study.

ABSTRACT: INTRODUCTION:To investigate the absolute bioavailability of esaxerenone and the effects of food on its pharmacokinetics (PK) after a single oral dose in healthy Japanese subjects. METHODS:Twenty-four Japanese males aged 20-45 years were randomised to six groups (each n?=?4) in this single-centre, open-label, three-way, three-period crossover study. Esaxerenone (5 mg) was administered in the fasting state as a single oral dose, single intravenous infusion over 1 h, or in the postprandial state as a single oral dose. Plasma samples were taken before and during the 96 h after drug administration. Drug concentrations were measured using liquid chromatography-tandem mass spectrometry. PK parameters were calculated using noncompartmental analysis, and safety was assessed. RESULTS:After fasting intravenous administration, total body clearance was 3.69 L h-1 and volume of distribution was 92.7 L. The plasma concentration-time profile of esaxerenone was similar after fasting and postprandial administration. Absolute bioavailability of a single oral 5-mg dose of esaxerenone was 89.0% in the fasting state and 90.8% postprandially. Point estimates (1.010 and 1.019, respectively) and 90% confidence intervals for geometric least squares mean peak plasma concentrations and area under the plasma concentration-time curve ratios after postprandial versus fasting oral esaxerenone were within the prespecified range (0.80, 1.25). No severe adverse events occurred throughout the study. CONCLUSIONS:Esaxerenone has a high absolute bioavailability of approximately 90% and food has no effect on esaxerenone PK after a single oral dose of 5 mg in healthy Japanese subjects. Additionally, no safety concerns were identified. CLINICAL TRIAL REGISTRATION:JapicCTI No. 163452. FUNDING:Daiichi Sankyo Co., Ltd.

Project description:IntroductionThe purpose of this study was to evaluate the absolute bioavailability (BA) of AG-221 following a single oral dose of 100 mg AG-221 and an intravenous (IV) dose of ~ 100 μg AG-221 containing approximately 300 nCi of [14C]-AG-221.MethodsThis was a phase 1, open-label study. Six subjects who met all of the inclusion criteria and none of the exclusion criteria were enrolled in the study. After an overnight fast of at least 10 h, the subjects received an oral dose (coated tablet) of 100 mg of AG-221 at 0 h on dosing day. Four hours after the oral dose, the subjects received 100 μg AG-221 containing ~ 300 nCi of [14C]-AG-221 administered as an IV bolus. Blood samples were collected and analyzed for plasma concentrations of AG-221 and [14C]-AG-221 using a validated liquid chromatography with tandem mass spectrometry (LC-MS/MS) system and high-performance liquid chromatography (HPLC) fractionation followed by accelerator mass spectrometry analysis (AMS), respectively. Safety was evaluated throughout the study.ResultsThe absolute BA after a 100-mg oral dose of AG-221 was measured as 57.2%. While the total clearance was 1.37 L/h, ~ 1/60 of the liver blood flow in a typical 70-kg human subject, the first-pass extraction was estimated to be less than 2%, assuming that the total clearance was entirely due to liver metabolism. Thus, the fraction of the AG-221 dose absorbed was at least 50%. AG-221 was safe and well tolerated when given under fasted conditions in a single 100-mg dose as a coated tablet with a microtracer [14C]-AG-221 solution, as few drug-related treatment-emergent adverse events (TEAEs) were reported. No clinically significant changes or findings were noted in the clinical laboratory evaluations, vital sign measurements, and electrocardiograms (ECGs) performed during this study.ConclusionsIn healthy subjects under fasting conditions, the absolute BA following oral administration of a 100-mg AG-221 tablet was 57.2%. AG-221 was safe and well tolerated in healthy male subjects when administered as a single 100-mg film-coated tablet plus 100 µg [14C]-AG-221 given intravenously.Trial registrationClinicalTrials.gov identifier, NCT02443168.FundingCelgene Corporation.

Project description:AimsTo characterize the pharmacokinetics, pharmacodynamics and safety of esaxerenone, a mineralocorticoid receptor antagonist, in healthy adult Japanese men.MethodsDouble-blind, placebo-controlled, sequential, dose-escalation studies were conducted in subjects randomized to receive oral once-daily esaxerenone (ranges: 5-200 mg [single-dose]; 10-100 mg over 10 days [multiple-dose]) or placebo under fasting conditions. Plasma concentrations were analysed by liquid chromatograph-tandem mass spectrometry. Pharmacokinetic parameters were determined by noncompartment analysis. Plasma/urine levels of pharmacodynamic biomarkers for mineralocorticoid receptor activity were evaluated.ResultsIn total, 48/48 and 39/40 subjects completed the single- and multiple-dose studies, respectively. Exposures were generally dose-proportional. The tmax , t1/2 and CL/F remained unchanged, independent of dose; the respective ranges were 1.5-4.0 h, 22.3-25.1 h, and 4.0-5.2 l h-1 (multiple-dose study). Vz /F ranged from 136.5 to 283.7 l in the multiple-dose study, and exposure reached steady state by day 4. The mean observed accumulation ratio, by dose, ranged from 1.36-1.98. The urinary Na+ /K+ ratio increased after single-dose administration; however, its relationship to the doses tested remains unclear. Plasma renin activity, active renin concentration and aldosterone concentration increased dose-dependently. Although blood potassium levels increased dose-dependently in the multiple-dose study (reaching a maximum mean ± standard deviation of 4.63 ± 0.354 mmol l-1 in the 100-mg group), no safety/tolerability-related problems were detected in either study.ConclusionsExposure levels in healthy adults receiving esaxerenone were generally dose-proportional. Dose-dependent changes in plasma pharmacodynamic biomarkers for the mineralocorticoid receptor were identified during multiple-dose treatment and support the pharmacological activity of esaxerenone. No important safety concerns were identified.

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:Background and objectivesYLB113 is being developed as a biosimilar of the antitumor necrosis factor-alpha antagonist etanercept, which is approved for the treatment of moderate-to-severe rheumatoid arthritis (RA) and other chronic immune-mediated inflammatory diseases. An open-label, crossover, pharmacokinetic study was conducted to compare the relative bioavailability and safety of YLB113 and the etanercept reference product (RP) Enbrel®.MethodsHealthy male subjects aged 18-50 years were randomized to receive a single subcutaneous dose of YLB113 in one period and the etanercept RP in another period. A washout period of 28 days separated the two treatment periods. Blood samples were collected for pharmacokinetic analysis predose and until 480 h postdose during both periods.ResultsOverall, 52 subjects were enrolled, including 51 subjects who completed the first period and 43 subjects who completed the second period. The 90% confidence intervals for the least squares means derived from an analysis of the log-transformed pharmacokinetic parameters maximum serum concentration (Cmax), area under the serum concentration-time curve (AUC) from 0 to the last measurable concentration (AUC(0-t)) and AUC from 0 to infinity (AUC(0-∞)) for etanercept were between the limits of 80 and 125%. Thus, YLB113 met the bioequivalence criterion. YLB113 and the etanercept RP were well tolerated, with 24 subjects reporting 53 adverse events, including 42 mild and 11 moderate events. Treatment-emergent adverse events were reported by 14 and 16 subjects following the administration of YLB113 and the etanercept RP, respectively.ConclusionsA single dose of YLB113 exhibited pharmacokinetic and safety profiles comparable with those of the etanercept RP in healthy adult male subjects. Therefore, YLB113 and the etanercept RP can be considered bioequivalent. These findings support the continued development of YLB113 for use in patients with RA.Jordan food & drug administration unique trial number31/Clinical/2018.

Project description:UnlabelledInhaled umeclidinium (UMEC) and the combination of inhaled UMEC with vilanterol (UMEC/VI) are approved maintenance treatments for chronic obstructive pulmonary disease in the US and EU. This was a randomized, open-label, three-period crossover, single- and repeat-dose study to assess the pharmacokinetics (PK), safety, and tolerability of inhaled UMEC/VI 62.5/25 μg (delivering 55/22 μg) and UMEC/VI 125/25 μg (delivering 113/22 μg) compared with their monotherapy components (UMEC 62.5 μg, UMEC 125 μg and, VI 25 μg [delivering 55, 113, and 22 μg, respectively]) in healthy Chinese subjects (n=20). UMEC and VI were rapidly absorbed following single and repeat dosing (time to maximum plasma concentration [tmax]: UMEC = 5 min; VI = 5 min). The median tlast was 2–4 h for UMEC and 1–2 h for VI following single doses of UMEC/VI and UMEC monotherapy (both doses). UMEC reached steady-state prior to Day 10; steady-state for VI could not be assessed. UMEC accumulation following repeat dosing was 11–34% based on Cmax and 19–59% based on area under the concentration-time curve from time zero to 2 h (AUC(0-2)). VI accumulation following repeat dosing was 25–66% based on Cmax and 17–43% based on AUC(0-2). The evidence was not sufficient to suggest that systemic exposure was substantially different between UMEC/VI combination therapy and the constituent monotherapies following single or repeat dosing. Following both single- and repeat-dose administration, the inter-subject coefficient of variation for all UMEC PK parameter estimates ranged from 12% to 165% for all treatments, indicating a wide range of variability in inhaled PK parameters. Twelve subjects experienced ≥1 adverse event (AE). Six subjects experienced ≥1 treatment-related AE; the most commonly reported treatment-related AE was chest discomfort (n=3 [15%]). No clinically important changes in vital signs or electrocardiogram parameters were reported. These data suggest that single- and repeat-dose administration of UMEC/VI combination therapy in healthy Chinese subjects did not result in substantial differences in systemic exposure compared with UMEC and VI as monotherapies.Trial registrationClinicaltrials.gov NCT01899638 NCT01899638.
