POSEIDON Trial Summary
This trial is testing a new device to help people with ascites, a buildup of fluid in the abdomen. The device is implanted and then removed after 24 months.
Who is the study for?
Adults with liver cirrhosis and refractory or recurrent ascites not suitable for TIPS, who've had multiple fluid removal procedures. They must be able to consent, follow study rules, operate the device, have a life expectancy of at least 6 months post-implant, and women must use contraception.Check my eligibility
What is being tested?
The Alfapump System is being tested in patients with hard-to-treat ascites. Participants will be observed for three months before implantation and followed up for two years after receiving the pump to evaluate its effectiveness and safety.See study design
What are the potential side effects?
Potential side effects are not explicitly listed but may include risks associated with surgical implantation such as infection, bleeding, device malfunction or complications related to managing ascites.

Study Objectives
Outcome measures can provide a clearer picture of what you can expect from a treatment.Primary outcome measures
Combined rate of open surgical reintervention due to pump system related adverse event or to restore pump functionality, pump explant due to pump system related adverse event, or pump system related death
Per-patient ratio of post-implant to pre-implant with respect to average monthly number of therapeutic paracentesis
Proportion of patients with at least 50% reduction in number of therapeutic paracenteses from the pre-observation period to post-observation period
Secondary outcome measures
Change in Ascites-Q Score
Change in SF-36 Physical Component Score
Change of cumulative volume of ascitic fluid removed by means of therapeutic paracentesis
