Donation of plasma (500 mL) within 7 days prior to drug administration. Donation or loss of whole blood (excluding the volume of blood that will be drawn during the screening procedures of this study) prior to administration of the study medication as follows: 50 mL to 300 mL of whole blood within 30 days, 301 mL to 500 mL of whole blood within 45 days, or more than 500 mL of whole blood within 56 days prior to drug administration.
