• •5. Known clinical central nervous system (CNS) symptoms deemed by the investigator to be related to leukemic CNS involvement.
• •6. QTcF (QT interval corrected for heart rate by the Fridericia formula) \> 470 ms, calculated as the mean value of the triplicates taken at least 2 minutes apart at baseline or QTcF prolongation deemed clinically relevant by the investigator.
