Pharmacokinetics and Pharmacodynamics of Esomezol DR, a New Dual Delayed-Release Formulation of Esomeprazole 20 Mg or 40 Mg, in Healthy Subjects.

ABSTRACT:

Background

Esomeprazole, a proton pump inhibitor (PPI), is widely used to treat acid-related disorders, but it has short plasma half-life which can cause insufficient gastric acid suppression, such as nocturnal acid breakthrough. A new dual delayed-release (DR) formulation of esomeprazole (Esomezol DR), was developed to extend the duration of gastric acid suppression.

Purpose

This study aimed to evaluate the pharmacokinetics (PKs) and pharmacodynamics (PDs) of esomeprazole for the DR formulation compared to a conventional enteric-coated (EC) formulation (Nexium) in healthy male subjects.

Methods

Two randomized, open-label, multiple-dose, two-way crossover studies with esomeprazole 20 mg and 40 mg were conducted. Subjects received the DR formulation or the EC formulation once daily for 7 days in each period with a 7-day washout. Serial blood samples were collected up to 24 hours after the 1st dose, and 24-hour intragastric pH was continuously monitored before the 1st dose as baseline and after the 1st and the 7th dose.

Results

In 20 mg and 40 mg dose groups, 38 and 44 subjects completed the study, respectively. The DR formulation exhibited the dual-release pattern of esomeprazole, resulting in more sustained plasma concentration-time profiles compared to the EC formulation. The systemic exposure of esomeprazole for the DR formulation was comparable to that for the EC formulation, showing the similar area under the plasma concentration-time curve. The 24-hour gastric acid suppression was also similar between the two formulations, while the inhibition during night-time (22:00-06:00) showed a better tendency in the DR formulation.

Conclusion

The sustained exposure of esomeprazole in the DR formulation led to well-maintained and higher acid inhibition compared to the EC formulation, especially during the night-time. These results suggest that the DR formulation can be an alternative formulation to the conventional EC formulation, expecting the potential of relieving nocturnal acid-related symptoms.

Project description:BackgroundYYD601 was developed as a novel dual delayed release (DDR) formulation of esomeprazole to prolong the plasma esomeprazole concentration and extend the duration of acid suppression.PurposeThe pharmacokinetic (PK) and pharmacodynamics (PD) characteristics of YYD601 after single and multiple oral administrations were investigated in healthy Korean adults under fasting and fed conditions, and compared with the original esomeprazole capsule.MethodsIn the single-center, randomized, open-label, parallel-design, two-period study, thirty two volunteers were enrolled into four dosing groups, including esomeprazole 40-mg (group A), YYD60130-mg (group B), YYD601 40-mg (group C), and YYD601 60-mg (group D) once daily for 5 days. Blood samples were collected for PK analysis, before and up to 24 h after dosing. For PD characteristics of YYD601, the percentages of time with intragastric pH > 4 over a 24-h period and during night-time following multiple oral administrations were evaluated.ResultsA total of 27 subjects completed the study. YYD601 showed a dual-peak PK profile under fasting condition, with delayed Tmax, compared with conventional formulation. There were no significant differences in the AUC values adjusted for dose between the three YYD601 dosage groups and the conventional esomeprazole 40 mg. The esomeprazole AUC following single and multiple administration decreased with food intake by approximately 33%. YYD601 showed a linear pharmacokinetic profile in the dose range studied. There was no statistically significant difference in increase in mean percentage of time with intragastric pH > 4 for 24-hour and during night-time between the three different doses of YYD601 and the conventional formulation. The treatments were well-tolerated during the study and no serious adverse events were observed.ConclusionYYD601 30 mg has a comparable effect on gastric acid inhibition as conventional esomeprazole 40 mg following once daily oral administration. Single and multiple oral dosing of YYD601 up to 60 mg were safe and well-tolerated throughout the study.Clinical trial registryhttp://clinicaltrials.gov, NCT03558477 (date of registration: June 15, 2018; study period: between October 2017 and February 2018).

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.
