| Current Primary Outcome Measures | Number of Participants Who Experienced Cardiac Events (Level 1 or 2), or Inability to Administer Trastuzumab Either During the 8 Cycles of Chemotherapy or According to Package Insert for a Total Duration of 1 Year [Time Frame: 8 cycles of chemotherapy and subsequently one year of planned trastuzumab treatment] [Designated as safety issue: Yes]Cardiac events defined as: Level 1: Cardiac death due to heart failure (HF), myocardial infarction or arrhythmia, or probable cardiac death defined as sudden, unexpected death within 24 hours of a definite or probable cardiac event, or severe symptomatic HF, concomitant with a left ventricular ejection fraction (LVEF) drop of >10 percentage points from baseline and to ≤50% LVEF Level 2: Asymptomatic systolic dysfunction or mildly symptomatic HF concomitant with an LVEF drop of >10 percentage points from baseline and to <50% LVEF; the LVEF drop was to have been confirmed within 3-4 weeks. |
