Lab requirements

Cardiac function

LVEF ≥ 50% by either echocardiography (ECHO) or multiple-gated acquisition (MUGA) within 28 days before enrollment. No symptomatic CHF (NYHA II-IV), serious arrhythmia, recent MI/unstable angina/CVA/TIA within 6 months, uncontrolled hypertension, or significant ECG abnormalities.

Has LVEF ≥ 50% by either echocardiography (ECHO) or multiple-gated acquisition (MUGA) within 28 days before enrollment. Has a medical history of symptomatic congestive heart failure (CHF) (NYHA classes II-IV) or serious cardiac arrhythmia requiring treatment. Has a medical history of myocardial infarction or unstable angina or cerebrovascular accident including transient ischemic attack (TIA) within 6 months before first dose. Or has uncontrolled hypertension (defined as systolic blood pressure > 160 mmHg or diastolic blood pressure > 100 mmHg). Has any clinically important abnormalities in rhythm, conduction or morphology of resting electrocardiogram (ECG), e.g., complete left bundle branch block, third-degree heart block, second-degree heart block, or PR interval > 250 milliseconds (ms). Has an average of Fredericia's formula-QT corrected interval (QTcF) prolongation to > 470 millisecond (ms) based on a 12-lead electrocardiogram (ECG) in triplicate.
