- Registration Number
- NCT01494402
- Lead Sponsor
- AstraZeneca
- 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.
- Detailed Description
A Phase I, Open label, Randomized, Single center, 2 way Crossover Bioequivalence Study Comparing D961S (a Fixed-dose Combination Capsule of Esomeprazole 20 mg and Acetylsalicylic Acid 81 mg) with a Free Combination of Esomeprazole Capsule 20 mg + Buffered Acetylsalicylic Acid Tablet 81 mg After Repeated Oral Administration in Japanese Healthy Male Subjects

- Primary Outcome Measures
Name Time Method 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 6 All 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 6 All PK variables at each time point will be listed by subject and summarised for each treatment using appropriate descriptive statistics.
- Secondary Outcome Measures
Name Time Method 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.
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 SA Baseline, which is 30 minutes before dose at day 5 of treatment period, till day 6 All 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.
