 24. QTc with Bazetts correction measurable at 480msec on screening ECG. Note: If a patient has QTc 480msec on screening ECG, the screen ECG may be repeated twice at least 24 hours apart. The average QTc from the three screening ECGs must be 480msec in order for the patient to be eligible for the study. Patients who are receiving a drug that has a risk of QTc prolongation see Appendix III, Table 2 are excluded if QTc is 460msec.
