Has a history of symptomatic congestive heart failure (New York Heart Association classes II-IV) or a serious cardiac arrhythmia requiring treatment
Has a corrected QT interval by Fridericia's formula (QTcF), of >470 ms based on the average of triplicate 12-lead electrocardiogram (ECG) per local read
Has a history of (non-infectious) interstitial lung disease (ILD)/pneumonitis that required corticosteroids, current ILD/pneumonitis, or where suspected ILD/pneumonitis cannot be ruled out by imaging at screening.
