In Cycles 1 and 2, additional blood will be drawn for pharmacokinetic (PK) testing. PK testing measures the amount of study drug in the body at different time points. For participants receiving the study drug over 60 minutes, this blood (about 1 teaspoon each time) will be drawn on Day 1 (before you receive the study drug and at 5, 10, 20 and 40 minutes after the start of the dose, and then at 1, 1½, 2, 3, 4, and 6 hours after the start of the dose). Blood will also be drawn on Day 2 (24 hours after the start of the dose).
