Exclusion Criteria: - History of any clinically significant disease or disorder which, in the opinion of the investigator, may either put the potential subject at risk because of participation in the study, or influence the results or the potential subject's ability to participate in the study.

• Any abnormalities in alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), urea, creatinine, thyroid-stimulating hormone (TSH), International Normalised Ratio (INR), activated partial thromboplastin time (aPTT), white blood cell (WBC) count, haemoglobin (Hb) or platelet count. Any other abnormal haematology, clinical chemistry, coagulation or urinalysis results, as judged with an unacceptable deviation that is considered to be clinically significant by the investigator.

• Any clinically significant abnormal findings in vital signs, as judged by the investigator. at screening and at baseline (Day -1 of Treatment period 1), defined as:

• Systolic blood pressure < 90mmHg or ≥ 140 mmHg

• Diastolic blood pressure < 50mmHg or ≥ 90 mmHg

• Pulse < 50 or > 85 beats per minute (bpm)

• Current smokers or those who have smoked or used nicotine products within the previous 3 months.

• 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, hematemesis, melena, haemoptysis, severe epistaxis, severe thrombocytopenia, intracranial haemorrhage; or rectal bleeding within 1 year prior to screening; or history suggestive of peptic ulcer disease; or at the discretion of the investigator.

• History of a clinically significant non-traumatic bleed or clinically significant bleeding risk, as judged by the investigator.

• Use of aspirin, ibuprofen, non-steroidal anti-inflammatory drugs (NSAIDs), or any other drug known to increase the propensity for bleeding for 2 weeks before randomisation.

• Platelet count less than 150 x 109/L.

Criteria applicable to insertion of a nasogastric tube:

• History of severe midface trauma and/or recent nasal surgery.

• History of coagulation abnormality, oesophageal varices or stricture, recent banding or cautery of oesophageal varices, and/or alkaline ingestion, at the discretion of the investigator.
