Study summary

The study is a multi-center, prospective, open label, uncontrolled feasibility study enrolling 30 patients with refractory or recurrent ascites and cirrhosis at up to 6 sites. Patients will be enrolled during a 6 month enrollment phase after which data will be collected for 12months with an initial analysis after 3 months. Extended follow-up for safety monitoring purposes will continue for the lifetime of the patient or until the device is explanted.

Study arms

  • Experimental
    alfapump system

    The Sequana Medical alfapump system is an implanted subcutaneous device with a rechargeable battery that moves ascitic fluid from the peritoneal cavity to the urinary bladder where it is eliminated by spontaneous diuresis.

    Device: alfapump system

What researchers measure

Primary outcomes

  1. Incidence and severity of serious adverse events related to the device and its implantation.

    Time frame: 12 months

Secondary outcomes

  1. Assess the overall requirement for large volume paracentesis

    Assess the overall requirement for large volume paracentesis by investigation of: * the number of large volume therapeutic paracentesis events and all paracentesis events * the annualized rate of large volume therapeutic paracentesis and of all paracentesis events * the cumulative volume of ascites removed through all paracentesis events • Assess the overall requirement for large volume paracentesis by investigation of: * the number of large volume therapeutic paracentesis events and all paracentesis events * the annualized rate of large volume therapeutic paracentesis and of all paracentesis events * the cumulative volume of ascites removed through all paracentesis events

    Time frame: 12 months

  2. Nutritional status

    Nutritional status o evaluate changes in serum prealbumin

    Time frame: 12 months

  3. Evaluate patient quality of life

    Evaluate patient quality of life * chronic liver disease questionnaire (CLDQ) * PLD questionnaire * ECOG performance status

    Time frame: 12 months

  4. Overall survival

    Time frame: 12 months
