- Registration Number
- NCT06510413
- Lead Sponsor
- Frontier Biotechnologies Inc.
- Brief Summary
This study was a single-center, randomized, open-label, two-agent, two-cycle, double-cross bioequivalence trial.
- Detailed Description
The objectives of this study are to evaluate the difference of absorption degree and absorption rate of two kinds of patches( FB3002 vs. Loxonin®) in Chinese healthy population, and to assess the bioavailability of these two patches.

- Primary Outcome Measures
Name Time Method AUC0-∞ of loxoprofen and its trans-OH 0-72 hours Area under the plasma concentration curve from time 0 to ∞ (AUC0-∞). 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.
Cmax of loxoprofen and its trans-OH 0-72 hours Maximum plasma concentration. 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.
AUC0-T of loxoprofen and its trans-OH 0-72 hours Area 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.
- Secondary Outcome Measures
Name Time Method Tmax of loxoprofen and its trans-OH 0-72 hours Time to reach maximum plasma concentration
t1/2 of loxoprofen and its trans-OH 0-72 hours Apparent terminal elimination half-life
λz 0-72 hours Apparent terminal elimination rate constant
Adverse Events 0-14 days All of the adverse events will be reported
AUC_%Extrap 0-72 hours Percentage of AUCINF(_obs, _pred) due to extrapolation from Tlast to infinity
Irritation score 0-14 days A combined irritation score should be calculated by adding the "dermal response" score and the numeric equivalent for "other effects" letter score.
