Inclusion criteria
* Healthy male and female volunteers aged 18 to 50 years (inclusive) with suitable veins for cannulation or repeated venepuncture * Have a body mass index between 18 and 30 kg/m2 (inclusive) and weigh at least 50 kg (110 pounds \[lbs\]) and no more than 100 kg (220 lbs). * Provision of signed and dated, written informed consent prior to any study specific procedures
Exclusion criteria
* History of any clinically significant disease or disorder which, in the opinion of the Investigator, may either put the volunteer at risk because of participation in the study, or influence the results or the volunteer's ability to participate in the study * History of haemophilia, von Willebrand's disease, lupus anticoagulant or other diseases/syndromes that can either alter or increase the propensity for bleeding * A personal history of vascular abnormalities including aneurysms; a personal history of severe haemorrhage, haematemesis, melena, haemoptysis, severe epistaxis, severe thrombocytopenia, intracranial haemorrhage; or rectal bleeding within 3 months prior to the screeening visit; or history suggestive of peptic ulcer disease * History of frequent and/or significant nose bleed or clinically significant non traumatic bleed, bruise/haematoma or any other clinically significant bleeding risk, as judged by the Investigator
