Pharmacokinetics and bioequivalence assessment of optimized directly compressible Aceclofenac (100 mg) tablet formulation in healthy human subjects.

ABSTRACT: 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 50?g/mL to 0.05?g/mL with LLOQ and LOD of 0.05?g/mL and 0.025?g/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±1.251?g/mL and 8.478±0.913?g/mL. The AUC0-t and AUC0-? of the test and the reference were computed to be 20.890 ±2.2021?g/mL.h, 23.272 ±1.914 ?g/mL.h and 19.850 ±2.911 ?g/mL.h, 22.890 ± 2.110 ?g/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:Background and objectiveVenetoclax is an approved BCL-2 inhibitor, currently under evaluation in different hematological malignancies in adult and pediatric populations. Venetoclax is available as 10, 50, and 100 mg tablets. To provide an alternative to patients who find taking the commonly prescribed 100 mg tablet a challenge, the interchangeability of lower-strength tablets with the 100 mg tablet was investigated. Additionally, newly developed oral suspension powder formulations to facilitate dosing in pediatrics were evaluated.MethodsPharmacokinetic data from 80 healthy female participants from three phase I studies were utilized to evaluate the bioavailability of (1) 10 and 50 mg tablets relative to a 100 mg tablet; (2) 0.72 and 7.2% (drug to total weight) oral powder formulations relative to the 100 mg tablet; and (3) oral powder formulations administered using different vehicles (apple juice, apple sauce, and yogurt) relative to water under fed conditions.ResultsBioavailability assessments at a 100 mg dose of venetoclax demonstrated bioequivalence across the 10, 50, and 100 mg tablet strengths. Oral powder formulations met the bioequivalence criteria (0.80-1.25) with respect to area under the concentration-time curve to time of the last measurable concentration (AUCt) and to infinite time (AUC∞) but exhibited a slightly lower maximum plasma concentration (Cmax). Exposure-response analyses were utilized to demonstrate that the lower Cmax observed with the powder formulations is not clinically meaningful. The delivery vehicles tested did not affect the bioavailability of venetoclax oral powder formulations.ConclusionsThe smaller-sized tablets (10 and 50 mg) and the newly developed oral powder formulations of venetoclax can be used interchangeably with the 100 mg tablets to improve the patients' experience, while maintaining adequate exposure.
