Brief Summary:
The study will be a single centre, open-label trial. The patients will have a diagnosis of refractory ascites and will meet specified inclusion/exclusion criteria Informed consent will be obtained from all patients. All patients will have an alfapump surgically inserted and in addition will receive 8g of salt-poor Human Albumin Solution (20%) per 1 litre of Ascites drained. This Intravenous administration will be intermittent (every month) and will take place as a day patient. Patients will also receive standard of care, which may include, but is not limited to, administration of diuretics, paracentesis and consideration for orthotopic liver transplantation.

Detailed Description:

The study will be a single centre, open-label trial. The patients will have a diagnosis of refractory ascites and will meet specified inclusion/exclusion criteria Informed consent will be obtained from all patients. All patients will have an alfapump surgically inserted and in addition will receive 8g of salt-poor Human Albumin Solution (20%) per 1 litre of Ascites drained. This Intravenous administration will be intermittent (every 2 weeks) and will take place as a day patient. Patients will also receive standard of care, which may include, but is not limited to, administration of diuretics, paracentesis and consideration for orthotopic liver transplantation.

The primary objective of the study is to assess whether intermittent human albumin replacement in accordance with large volume paracentesis guidelines (8g/L ascites drained) can prevent the development of renal dysfunction at the 3-month assessment. This would potentially guide the clinical use of the alfapump system.

The secondary objectives of the study are to address the objectives of a previous alfa pump study /sub study, to allow comparison of the proposed study data to that generated in the previous studies. These will be measured at the 1-month and 3-month time points.
