About the POSEIDON study

POSEIDON is a single-arm, open-label and within subject cross-over study of the alfapump in patients with recurrent or refractory ascites due to liver cirrhosis and is being conducted in approximately 20 centres across the US and Canada. All patients have been enrolled in the study and implanted with the alfapump. Patients enrolled in the Pivotal Cohort entered into a three-month pre-implant observation period before they are implanted with the alfapump and will be used for primary endpoint analysis. The study allowed to enrol additional patients in a Roll-In Cohort to ensure new centres were experienced with the alfapump implantation prior to enrolling patients in the Pivotal Cohort.

The primary effectiveness outcomes of the study include the proportion of patients with a 50% reduction in the average frequency of therapeutic paracentesis per month in the post-implant observation period (month four to month six post-implantation) as compared to the pre-implant observation period. The primary safety endpoint is the rate of alfapump-related re-interventions adjudicated by the Clinical Events Committee. Patients will be followed for up to two years post-implant for analysis of secondary outcome measurements including safety (device and/or procedure-related adverse events), quality of life (assessed by general SF36 as well as disease-specific Ascites Q questionnaires), nutritional status, health economics and overall survival.

About fluid overload in liver cirrhosis (AKA ascites)

Fluid accumulation in the abdomen is a significant and common complication of liver cirrhosis. Approximately 10% of these patients do not respond to diuretic drugs and most require recurrent external drainage (AKA paracentesis), an invasive and painful procedure that only provides temporary benefit, require frequent hospitalizations and severely impacts their quality of life.

About Sequana Medical

Sequana Medical NV is a pioneer in treating drug-resistant fluid overload, a serious and frequent clinical complication in patients with liver disease, heart failure and cancer. Fluid overload is a well-recognized problem in these growing diseases, causing severe problems for the large number of patients for whom current medicines are no longer effective. These patients can have up to 15 liters of extra fluid in their bodies, causing major medical issues including increased mortality, repeated hospitalizations, severe pain, difficult breathing and restricted mobility that severely impacts daily life.

alfapump and DSR are Sequana Medical’s proprietary approaches that work with the body to remove this excess fluid, delivering major clinical and quality of life benefits for patients and reducing costs for healthcare systems. Sequana Medical is listed on Euronext Brussels (Ticker: SEQUA.BR) and headquartered in Ghent, Belgium. For further information, please visit www.sequanamedical.com.
