    The primary outcome will be patient survival with a functional alfapump system at 6 months.

    Measured: 6 months post-implant

Secondary outcomes (14)
  1. To assess occurrence of (major) reportable events.

    Reportable events are defined as any events per the definition in 9.1 and classified as renal event, variceal bleeding, hepatic encephalopathy an infection or assessed as related (not classified "improbable related" or "cannot be attributed" per the definitions below) to; the implant procedure, device or therapy by the treating physician.

    Measured: 2 years

  2. To assess safety at 1-month post implant for procedure related incidents.

    • Occurrence of adverse events considered related to implant, product or therapy by the treating physician

    Measured: 1 month post implant

  3. Clinical impact on liver and renal function in liver & renal blood lab panel

    Clinical impact as assessed by changes in Prealbumin

    Measured: 2 years

  4. Clinical impact on liver and renal function in liver & renal blood lab panel

    Clinical impact as assessed by changes in Albumin.

    Measured: 2 years

  5. Clinical impact on liver and renal function in liver & renal blood lab panel

    Clinical impact as assessed by changes in eGFR.

    Measured: 2 years

  6. Clinical impact on liver and renal function in liver & renal blood lab panel

    Clinical impact as assessed by changes in createnine.

    Measured: 2 years

  7. Impact of the alfapump on ascites symptoms related quality of life

    Ascites Questionnaire (pre implant \& at each visit after the first month post implant)

    Measured: 2 years

  8. Impact of the alfapump on ascites symptoms related quality of life

    SF-36 (pre implant at each visit after the first month post implant)

    Measured: 2 years

  9. Impact of the alfapump on ascites symptoms related quality of life on patient activity

    Assess change in physical activity pre- and post implant To assess daily activity and stress level of patients for up to 48 weeks following implant

    Measured: 1 week pre-implant, Day 0 Implant, 4 weeks-, 8 weeks-, 16 weeks-, 24 weeks- and 48 weeks post implant

  10. Impact of the alfapump on ascites symptoms related quality of life on patient activity

    Assess change in physical activity pre- and post implant To assess and evaluate sleep of patients for up to 48 weeks following implant

    Measured: 1 week pre-implant, Day 0 Implant, 4 weeks-, 8 weeks-, 16 weeks-, 24 weeks- and 48 weeks post implant

  11. Impact of the alfapump on ascites symptoms related quality of life on patient activity

    Assess change in physical activity pre- and post implant

    1. To assess daily activity and stress level of patients for up to 48 weeks following implant
    2. To assess and evaluate sleep of patients for up to 48 weeks following implant
    3. To assess patient's abdominal pain/discomfort, appetite, satiety, and tiredness
    4. To assess objective stress and inflammation parameters

    Measured: 1 week pre-implant, Day 0 Implant, 4 weeks-, 8 weeks-, 16 weeks-, 24 weeks- and 48 weeks post implant

  12. Impact of the alfapump on ascites symptoms related quality of life on patient activity

    Assess change in physical activity pre- and post implant To assess patient's abdominal pain/discomfort, appetite, satiety, and tiredness

    Measured: 1 week pre-implant, Day 0 Implant, 4 weeks-, 8 weeks-, 16 weeks-, 24 weeks- and 48 weeks post implant

  13. Impact of the alfapump on ascites symptoms related quality of life on patient activity

Questions about this trial

What is this clinical trial studying?

An observational study of Liver Cirrhoses and Malignant Ascites, run by Sequana Medical N.V. at 2 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What are the possible benefits and risks?

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Patient survival at 6 months post implant (time frame: 6 months post-implant). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Nov 2024.
