Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • pharmacokinetic profile of acetylsalicylic acid (ASA) and salicylic acid (SA) in terms of area under curve (AUC), maximum concentration at steady state (Css,max), time to reach maximum concentration (tmax) and terminal half- time (t1/2). [ Time Frame: Day 5 ] [ Designated as safety issue: No ]
    PK samples collected pre-dose and at 5mins, 10 mins, 20 mins, 30 mins, 40mins, 50 mins, 1hr 15 mins, 1.5hrs, 2 hrs, 2hr 30 mins, 3hrs, 3hr 30 mins, 4 hrs, 5 hrs, 6hrs, 8hrs,10 hrs, 12hrs post-dose.

Secondary Outcome Measures:
  • Description of the safety profile in terms of adverse events, blood pressure, pulse, ECG (Electrocardiogram), physical examination, safety labs [ Time Frame: Pre-dose up to 7 day after last dose ] [ Designated as safety issue: Yes ]
    No formal statistical tests will be performed. Abnormalities will be listed without statistical analysis
