Brief summary

The purpose of this study is to assess bioequivalence between D961S and esomeprazole/buffered ASA, safety, tolerability of esomeprazole in combination with ASA and pharmacokinetics (PK) of D961S, esomeprazole and buffered ASA following repeated administration in healthy male Japanese subjects.

Design outcomes

Primary

MeasureTime frameDescription
Description of bioequivalence of D961S to combination of esomeprazole + buffered ASA in terms of Area under the plasma concentration(AUCτ).Baseline, which is 30 minutes before dose at day 5 of treatment period, till day 6All PK variables at each time point will be listed by subject and summarised for each treatment using appropriate descriptive statistics.
Description of bioequivalence of D961S to combination of esomeprazole + buffered ASA in term maximum plasma concentration (Cmax,ss)Baseline, which is 30 minutes before dose at day 5 of treatment period, till day 6All PK variables at each time point will be listed by subject and summarised for each treatment using appropriate descriptive statistics.

Secondary

MeasureTime frameDescription
Description of D961S PK profile comparing to esomeprazole and ASA combination in terms of AUC0-t,ss, mean residence time (MRT), time to reach Cmax (tmax,ss) and t1/2,ss of esomeprazole and ASA, and AUCτ, Cmax,ss, AUC0-t,ss, MRT, tmax,ss and t1/2,ss of SABaseline, which is 30 minutes before dose at day 5 of treatment period, till day 6All PK variables and plasma concentrations of esomeprazole, ASA and SA at each time point will be listed by subject and summarised for each treatment using appropriate descriptive statistics.
Description of Safety and tolerability profile of esomeprazole in combination with ASA in terms of adverse events, clinical laboratory tests, blood pressure, pulse rate and body temperature.Pre-entry, Day 5 of treatment period and follow up (5-7 days after last dose)Descriptive statistics will be provided for all safety variables, and the analyses will be performed according to the actual treatment. No formal comparison will be performed.
