Bioequivalence

Brief summary

This study aims to investigate whether FABALOFEN 60 is bioequivalent to JAPROLOX® TABLETS after a single oral administration of each loxoprofen formulation in healthy subjects by assessing of pharmacokinetic properties including AUC, Tmax and Cmax and to evaluate the safety of test drug FABALOFEN 60 and reference drug JAPROLOX® TABLETS during drug administration.

Detailed description

This study is a randomized, single-dose, 2-sequence, 2-period, 2-treatment crossover study in 24 fed healthy subjects with an at-least-6-day washout period. The drug level in serum is detected by High-performance Liquid Chromatography (HPLC) to determine Cmax, AUC0-t and Tmax. Safety are evaluated during drug administration, blood sampling time, washout period and 1 week after the end of blood sampling for any adverse drug reactions.

Interventions

DRUGFABALOFEN 60

Dosage: Single dose of one tablet of test product in each period. Administration: 30 minutes before administration, subjects will receive a test meal (high-fat and high-calorie) and finish this meal in 30 minutes or less. Take 1 tablet of test product with 240 mL of water. Lying position or strenuous activities are not allowed within 2 hours post dose

DRUGJAPROLOX TABLET

Dosage: Single dose of one tablet of reference product in each period. Administration: 30 minutes before administration, subjects will receive a test meal (high-fat and high-calorie) and finish this meal in 30 minutes or less. Take 1 tablet of reference product with 240 mL of water. Lying position or strenuous activities are not allowed within 2 hours post dose

Design outcomes

Primary

MeasureTime frameDescription
AUC0-tUp to 8 hours post-administrationArea under the plasma concentration curve from time 0 to the last measured (AUC0-t). Analyzing AUC with ANOVA test to evaluate the 90% confidence interval for the ratio (Test/Reference) of the population mean with a logarithmic transformation prior to analysis with acceptance interval of 0.80 - 1.25.
CmaxUp to 8 hours post-administrationMaximum plasma concentration. Analyzing Cmax with ANOVA test to evaluate the 90% confidence interval for the ratio (Test/Reference) of the population means with a logarithmic transformation prior to analysis with acceptance interval of 0.80 - 1.25.
TmaxUp to 8 hours post-administrationTime until Cmax is reached. Tmax is analyzed with Wilcoxon non-parametric test

Secondary

MeasureTime frameDescription
Adverse EventsUp to approximately 14 daysThe number and type of adverse events will be reported from first drug administration (period 1) till 1 week after the second drug administration (period 2), including 6 days of washout period (total time is approximately 14 days)
