Based on the investigator's opinion of any active significant medical illness the subject may have. * Subjects who refuse to receive allogenic blood products or whose preoperative red blood cell volume is so low that a blood transfusion would be likely to be given perioperatively (preoperative hematocrit of \<24% or hemoglobin of \<8 g/dl) * Subjects who have participated in an investigational drug study within the past 30 days * Subjects who are pregnant or breastfeeding or women of childbearing potential in whom the possibility of pregnancy cannot be excluded by a negative pregnancy test and who are not using a reliable method of contraception * Planned use of other antifibrinolytic agents, e.g. aminocaproic acid or tranexamic acid * Subjects on chronic anticoagulant treatment with warfarin that cannot be temporarily discontinued for the surgical procedure (as per local practices)
