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.

Clinical Details

Official title: Study Into the Effects of Albumin Replacement Therapy on Renal and Circulatory Function in Patients Implanted With the Alfapump

Study design: Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: 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, measured by serum creatinine

Secondary outcome:

Assessment of circulatory haemodynamics, measured by non-invasive cardiac haemodynamics

Assessment of cirrhosis- related complications, measured by Incidence of specific cirrhosis-related complications

Assessment of the Overall Survival at 3 months, measured by survival

Assessment of impact on nutrition, measured by changes in body weight

Assessment of impact on nutrition, measured by changes in circumference of arm

Assessment of impact on nutrition, measured by changes in tricipital skinfold

Assessment of impact on nutrition, measured by changes in handgrip

Assessment of the need for large volume paracentesis, measured by the overall requirements of paracentesis

Assessment of impact on Systemic Inflammatory Response, measured by CRP

Assessment of impact on Systemic Inflammatory Response, measured by cytokines

Assessment of impact on Systemic Inflammatory Response, measured by function of the peripheral blood mononuclear cells

Assessment of levels of bacterial DNA in serum, measured by presence of bacterial DNA in blood

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.
