Trial to Assess the Effects of Vorapaxar (SCH 530348; MK-5348) in Preventing Heart Attack and Stroke in Patients With Atherosclerosis (TRA 2°P - TIMI 50) (P04737)

The time (in days) from study start to the first occurrence of any of the following clinical outcomes was recorded: CV death, MI, stroke, or UCR. A Clinical Endpoints Committee (CEC) reviewed and adjudicated each suspected efficacy endpoint event while blinded to treatment. Participants who did not have any endpoint event until last visit or participants who were lost to follow-up and had no event were censored at the time of last available information (last study visit). If a participant had a fatal event that was not part of a specific endpoint for analysis, they were censored at the time of death. The Kaplan-Meier estimate reports the percentage of participants who experienced CV death, MI, stroke, or UCR within 3 years from randomization.

Adverse events were categorized as "bleeding events" if the intensity, frequency, or type of the event was other or more than would be normally expected in the given situation (eg, mild nosebleed in a person who does not normally have nosebleeds, greater bruising than expected for a given injury, greater volume of blood loss than expected for a given procedure). The investigator graded the intensity of bleeding events according to the GUSTO cooperative group criteria as follows: Mild , Moderate or Severe and the grading was adjudicated by the CEC. The Kaplan-Meier estimate reports the percentage of participants who experienced GUSTO moderate or severe bleeding within 3 years from randomization.

Adverse events were categorized as "bleeding events" if the intensity, frequency, or type of the event was other or more than would be normally expected in the given situation (eg, mild nosebleed in a person who does not normally have nosebleeds, greater bruising than expected for a given injury, greater volume of blood loss than expected for a given procedure). The investigator graded the intensity of bleeding events according to the Thrombolysis in Myocardial Infarction (TIMI) Study Group criteria as major, minor or other. "Clinically Significant Bleeding" was defined as the composite of TIMI Major bleeding, TIMI Minor bleeding, or bleeding that required unplanned medical or surgical treatment or unplanned laboratory evaluation even if it did not meet the criteria for TIMI major or minor bleeding. The Kaplan-Meier estimate reports the percentage of participants who experienced clinically significant bleeding within 3 years from randomization.
