• Subject must have a haemoglobin ≥ 9.0 g/dL at screening
• Subject must have a platelet count ≥ 100,000/mm3 at screening
• Subject is undergoing a planned open liver resection
• Male subjects must be willing and able to use adequate contraception from enrollment through to the 30 day follow-up visit
• During the surgery, the subject presents an identified target bleeding site (TBS) with oozing, mild or moderate bleeding, which conventional surgical techniques are insufficient to control and would otherwise be a candidate for standard haemostats
• During the surgery, subject presents no intraoperative complications, other than bleeding, that may interfere with study assessments as judged by the investigator

Exclusion criteria

• Subject is undergoing emergency surgical procedure
• Recipient of a liver transplant
• Females of child-bearing potential
• Active infection at the time of the liver resection
• International Normalized Ratio (INR) > 2.0 or APTT ratio > 2.0 at screening

• History of thromboembolic disease and/or thrombophilia
• Any other disease or condition that may affect normal blood clotting, for example thrombocytopenia, as judged by the investigator
• A known history of anaphylaxis or allergic reaction to human albumin, PEGylated proteins, yeast or moulds, porcine products or other components in the IMP
• Participation in another investigational drug or device research study within 30 days before and after enrolment in the current study
• Current known or suspected alcohol and/or drug abuse or dependence at the time of screening
• Any concurrent medical, surgical, or psychiatric condition that may, in the investigator's opinion, affect the subject's willingness or ability to meet all study requirements during the study duration
• During the surgery, subject presents severe bleeding where use of a topical haemostat would be inappropriate
• Subject is taking any prohibited medications
• BMI at screening of ≥35
