Effect of Various Dosing Conditions on the Pharmacokinetics of Oral Semaglutide, a Human Glucagon-Like Peptide-1 Analogue in a Tablet Formulation.

ABSTRACT:

Introduction

Oral semaglutide is a novel tablet formulation of the human glucagon-like peptide-1 analogue semaglutide. In two trials, the effects of prior food ingestion (food effect), post-dose fasting period and water volume with dosing (dosing conditions) on oral semaglutide pharmacokinetics were investigated.

Methods

Subjects received once-daily oral semaglutide for 10 days. In the food-effect trial, 78 healthy subjects were randomised 1:1:1 to fed (meal 30 min pre-dose; 240 mL water with dosing), fasting (overnight until 4 h post-dose; 240 mL) or reference (fasting overnight until 30 min post-dose; 120 mL) arms. In the dosing conditions trial, 161 healthy men were randomised into eight dosing groups (overnight fasted with 50/120 mL water and 15/30/60/120 min post-dose fasting). Semaglutide plasma concentrations were measured frequently until 504 h after the 10th dose.

Results

In the food-effect trial, limited or no measurable semaglutide exposure was observed in the fed arm, while all subjects in the fasting arm had measurable semaglutide exposure. Area under the semaglutide concentration-time curve (AUC_{0-24h,semaglutide,day10}) and maximum semaglutide concentration (C_{max,semaglutide,day10}) were numerically greater by approximately 40% for the fasting versus reference arm (p = 0.082 and p = 0.080, respectively). In the dosing conditions trial, AUC_{0-24h,semaglutide,day10} and C_{max,semaglutide,day10} were not different between water volumes (p = 0.541 and p = 0.676), but increased with longer post-dose fasting (p < 0.001).

Conclusion

Administration of oral semaglutide in the fasting state with up to 120 mL water and at least 30 min post-dose fasting results in clinically relevant semaglutide exposure. These dosing conditions have been used in the oral semaglutide phase 3 trials and are part of the approved label.

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.
