• Left ventricular ejection fraction (LVEF) >= 50%

  • Note: Echocardiogram to be performed within 42 days prior to day 1 of protocol therapy

• Women of childbearing potential (WOCBP): Negative urine or serum pregnancy test. (performed within 14 days prior to Day 1 of protocol therapy unless otherwise stated)

  • If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
