Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate equivalence in inhibiting platelet aggregation and platelet thromboxane production between acetylsalicylic acid tablets 50 mg administered twice daily and acetylsalicylic acid tablets 100 mg administered once daily.;Secondary Objective: •To evaluate sTxB2 levels and platelet aggregation response in obese and non-obese patients •To evaluate pharmacodynamics of sTxB2 in patients receiving acetylsalicylic acid tablets 50 mg twice daily and acetylsalicylic acid tablets 100 mg once daily (optional for patients who sign separate Informed Consent Form for additional biological material collection) •To evaluate safety ;Primary end point(s): 1)Difference in sTxB2 levels measured with analytical ELISA methods after 10 days of twice daily ASA 50 mg tablets compared to 10 days of once daily ASA 100 mg tablets. 2)Difference in platelet reactivity measured with VerifyNow® Aspirin Test after 10 days of twice daily ASA 50 mg tablets compared to 10 days of once daily ASA 100 mg tablets . ;Timepoint(s) of evaluation of this end point: Participants receive treatment and are monitored from the time of randomization until the end of the study. The expected duration of treatment in the study is 20 days, Regular evaluations are scheduled during the study.

Secondary

MeasureTime frame
Secondary end point(s): 1) Difference in sTxB2 levels in subgroup of obese (BMI = 35) patients 2) Difference in platelet reactivity in subgroup of obese (BMI = 35) patients 3) Difference in sTxB2 levels in subgroup of non-obese patients 4) Difference in platelet reactivity in subgroup of non-obese patients 5) Difference in pharmacokinetics measured with % of maximal TxB2 inhibition (Imax) 6) Difference in pharmacokinetics measured with TxB2 AUC0-24 7) Safety assessment. The number of AE/SAE after twice daily ASA 50 mg tablets compared to once daily ASA 100 mg tablets. ;Timepoint(s) of evaluation of this end point: Secondary endpoints will be assessed throughout the study
