Subjects who used any drugs or substances known to be strong inducers of CYP enzymes (formerly known as P450 enzymes) within 28 days prior to the first dose. Subjects who donated 50 to 499 mL of blood within 30 days and more than 499 mL within 56 days prior to the first dose. Subjects who, through completion of the study, would have donated in excess of: 500 mL of blood in 14 days; or 1500 mL of blood in 180 days; or 2500 mL of blood in 1 year. Subjects whose PR interval is >200 msec at screening and prior to dosing. Subjects whose QTc interval is >450 msec at screening and prior to dosing. Subjects who completed another clinical trial within 28 days prior to the first dose.
