Risk factors for Torsades de Pointes (TdP) including uncorrected hypokalemia or hypomagnesemia or history of clinically significant/symptomatic bradycardia. ii. On screening, inability to determine the corrected QT interval using Fridericia’s formula (QTcF) on the electrocardiogram (ECG; i.e., unreadable or not interpretable) or QTcF >470 msec (determined by mean of triplicate ECGs at screening).

- •Current participation in another interventional clinical trial. a. Subjects must agree not to participate in another clinical trial (other than observational trials) at any time during participation in CELC-G-
- •Subjects with rapidly progressive disease who are eligible for standard chemotherapy are excluded from enrollment.
