[9]Requires the use of concomitant medications that prolong the QT/QTc interval or has a known history of Long QT Syndrome or Brugada Syndrome. Has ECG abnormalities obtained at Visit 1 or at predose Visit 2 (baseline value) that, in the opinion of the investigator, are clinically significant with regard to the patient’s participation in the study; or has a QTc/JTc abnormality as determined below.
A patient with a normal QRS interval (=116 ms if male, =102 ms if female) will be excluded with mean QTc interval >458 ms (male) or >474 ms (female) at Visit 1 or predose Visit 2 (baseline value).
A patient with prolonged QRS interval (>116 ms if male, >102 ms if female) will be excluded with mean JTc interval >359 ms (male) or >382 ms (female) at Visit 1 or predose Visit 2 (baseline value).
