Bleeding Related to CABG – In TRITON-TIMI 38, 437 patients who received a thienopyridine
underwent CABG during the course of the study. The rate of CABG-related TIMI Major or
Minor bleeding was 14.1% for the Effient group and 4.5% in the clopidogrel group (see
Table 3). The higher risk for bleeding adverse reactions in patients treated with Effient
persisted up to 7 days from the most recent dose of study drug.

Bleeding Reported as Adverse Reactions – Hemorrhagic events reported as adverse
reactions in TRITON-TIMI 38 were, for Effient and clopidogrel, respectively: epistaxis (6.2%,
3.3%), gastrointestinal hemorrhage (1.5%, 1.0%), hemoptysis (0.6%, 0.5%), subcutaneous
hematoma (0.5%, 0.2%), post-procedural hemorrhage (0.5%, 0.2%), retroperitoneal
hemorrhage (0.3%, 0.2%), pericardial effusion/hemorrhage/tamponade (0.3%, 0.2%), and
retinal hemorrhage (0.0%, 0.1%).
Malignancies: During TRITON-TIMI 38, newly-diagnosed malignancies were reported
in 1.6% and 1.2% of patients treated with prasugrel and clopidogrel, respectively. The
