Primary outcomes

  1. Area under the concentration-time curve of the analyte in plasma at steady state, 13th dosing interval (AUCss,13)

    Time frame: Up to 168 hours after first drug administration

  2. Maximum concentration of the analyte in plasma at steady state, 13th dosing interval (Cmax,ss,13)

    Time frame: Up to 168 hours after first drug administration

  3. Pre-dose concentration of the analyte in plasma at steady state, 13th dosing interval (Cpre,ss,13)

    Time frame: Up to 168 hours after first drug administration

  4. Amount of the analyte eliminated unchanged in the urine per dosing interval i expressed as percent of applied dose and corrected for molecular weight differences (Ae% (i=1,...,13))

    Time frame: Up to 168 hours after first drug administration

Secondary outcomes

  1. Pre-dose concentration of the analyte in plasma for the i-th dosing interval (Cpre,i (i=1,4,7,10,11,12))

    Time frame: Up to 90 hours after first drug administration

  2. Plasma concentration of the analyte at 2 hours post-dose for the i-th dosing interval (C2h,i (i=10,11,12))

    Time frame: Up to 98 hours after first drug administration

  3. Terminal half life of the analyte in plasma (t1/2)

    Time frame: Up to 168 hours after first drug administration

  4. Percent swing of peak/trough concentrations of the analyte in plasma for the i-th dosing interval (%Swingi)

    Time frame: Up to 168 hours after first drug administration

    Calculated: (C2h,i - Cpre,i) / Cpre,i * 100% (i=10,11,12)

  5. Percent peak-trough fluctuation for the 13th dosing interval (%PTF13)

    Time frame: Up to 168 hours after first drug administration

    Calculated: (Cmax,ss,13 - Cpre,ss,13) * 8h / AUCss,13 * 100%)

  6. Percent fluctuation of area under the plasma concentration-time curve (AUCfluc,13)

    Time frame: Up to 168 hours after first drug administration

    Calculated: (AUCabove,13 - AUCbelow,13) / AUCabove,13

  7. Fibrinogen receptor occupancy levels

    Time frame: Up to 168 hours after first drug administration

  8. Number of patients with clinically relevant findings in laboratory tests

    Time frame: up to 168 hours after first drug administration

  9. Number of patients with clinically relevant findings in vital signs

    Time frame: up to day 8 after first drug administration

    systolic and diastolic blood pressure, pulse rate

  10. Number of patients with adverse events

    Time frame: Up to 3 days after last drug administration
