Ghent, Belgium – 23 December 2024 – Sequana Medical NV (Euronext Brussels: SEQUA, the "Company" or "Sequana Medical") , a pioneer in the treatment of drug-resistant fluid overload in liver disease, heart failure and cancer, today announces that it has received Premarket Approval (PMA) from the US Food and Drug Administration (FDA) to market alfa pump® for the treatment of recurrent or refractory ascites due to liver cirrhosis in the United States. With this major regulatory milestone, achieved earlier than market expectations, alfa pump is the first active implantable medical device in the US that automatically and continuously removes ascites from the abdomen into the bladder. The Company estimates there will be approximately 70,000 patients in the US with recurrent or refractory ascites, representing a market opportunity in excess of $2 billion for the alfa pump in 2025. This population is forecast to reach 130,000 patients by 2032, primarily driven by NASH/MASH and alcoholic liver disease1.
Dr. H.E. Vargas, M.D., Professor of Medicine for the Mayo Clinic College of Medicine (Phoenix, Arizona, US), POSEIDON Study Principal Investigator, commented: “The approval of alfa pump by the FDA opens the door to a breakthrough therapeutic option for patients with ascites. The introduction of the system will be welcome by patients, families and their care providers as this technology not only provides effective treatment, but also has been shown to improve quality of life4.”
Ian Crosbie, Chief Executive Officer of Sequana Medical, continued : "With a standard of care that has seen minimal change in thousands of years, today marks a huge milestone for the large and growing liver ascites community in the US. Our vision is to transform the lives of these patients. Recurrent or refractory liver ascites is a devastating condition with a terrible impact on the lives of our patients and their caregivers, not only for the painful and burdensome paracentesis procedure itself but also in the weeks leading up to each drainage. The POSEIDON clinical study results demonstrate that the alfa pump can virtually eliminate the need for therapeutic paracentesis, and improve patient quality of life, with a safety profile comparable to standard of care, delivering a twenty-first century solution that can allow these patients to take back their lives3,4. We wish to thank all the patients and investigators who made this possible by participating in the POSEIDON study. With over 1,000 alfa pump systems implanted to date, we look forward to starting commercialisation in H2 2025, bringing this innovative solution to many more patients in need.”
The Company is preparing for the US commercial launch of the alfa pump System in H2 2025, through a focused specialty sales force concentrating on the 90 liver transplant centers that represent the large majority of target customers. The Company has received FDA Breakthrough Device Designation for the alfa pump System and has applied, and expects to receive, NTAP (new technology add-on payments) which should facilitate patient access to the device. In addition to the existing ICD-10 procedure codes for the alfa pump procedure, the American Medical Association has granted six new CPT®5 III reimbursement codes, available for use by healthcare professionals and payors since July 1st, 2024, for procedures related to the alfa pump System.
“We are highly encouraged by the enthusiastic feedback for the alfa pump that we are receiving from the clinical community – there is a clear need for improved treatment options and we are putting in place the commercial team to deliver our novel therapy. Preparations for commercial launch are underway, and we are already working with target centers for the initial commercial launch planned for H2 2025. It is a huge privilege to bring such a breakthrough in therapy to the clinical and patient communities, and we are excited to work with them to establish alfa pump as the new standard of care” commented Martijn Blom, Chief Commercial Officer of Sequana Medical.
Timur Resch, Global Vice President QM/QA/RA at Sequana Medical, who has been leading the regulatory process since 2016, added: “The receipt of the PMA approval for our alfa pump System is a major milestone for our company and reflects many years of diligent work by the Sequana team. We wish to thank the FDA for its collaboration and support in bringing this highly important breakthrough device to US patients who will be very grateful for this new treatment option.”

About alfapump in recurrent or refractory ascites due to liver cirrhosis & the POSEIDON study
Recurrent or refractory ascites is a severe condition characterized by the accumulation of fluid in the abdomen. The current standard treatment involves therapeutic paracentesis, an invasive and burdensome procedure that drains ascites from the abdomen using a large needle over an extended period. The alfa pump is approved by the US FDA for the treatment of recurrent or refractory ascites due to liver cirrhosis. It is the first active implantable medical device in the US that automatically and continuously removes ascites from the abdomen into the bladder, where it is naturally eliminated through urination. To date, over 1,000 alfa pump systems have been implanted.
The US market of recurrent and refractory ascites due to liver cirrhosis is forecast to grow by an average of 9% per year, from approximately 70,000 patients in 2025 to 130,000 patients by 2032, primarily driven by the increasing prevalence of NASH / MASH6. The total market opportunity for alfa pump is estimated at over $2 billion in 2025, including approximately $500 million from the Company's initial priority target market of patients requiring at least 12 paracenteses per year.
The FDA's approval of the PMA is based on the successful execution of Sequana Medical's pivotal POSEIDON study, a landmark study across 18 centers in the US and Canada with a total of 69 patients implanted with the alfa pump. The primary effectiveness endpoints at six months post-implantation in the Pivotal Cohort7 exceeded the predefined thresholds with statistical significance, and primary safety endpoint data was in line with expectations8. Data at 12 months post-implantation continued to show a strong and durable clinical profile, virtually eliminating the need for therapeutic paracentesis and delivering an improvement in quality of life (as defined by subjective physical health (assessed by SF-36 PCS) and ascites symptoms (assessed by Ascites Q))9. At AASLD's The Liver Meeting in November 2024, key POSEIDON investigators reported that the alfa pump virtually eliminated the need for large volume paracentesis at 24 months, with overall survival of 62%10.
Data from the patient preference study and a matched cohort analysis of the NACSELD-III registry with the POSEIDON Pivotal Cohort indicated that US patients have a strong preference for the alfa pump vs standard paracentesis procedures and that the safety profile of the alfa pump is comparable to standard of care.11
About Sequana Medical
Sequana Medical NV is a pioneer in treating fluid overload, a serious and frequent clinical complication in patients with liver disease, heart failure and cancer. This causes major medical issues including increased mortality, repeated hospitalizations, severe pain, difficulty breathing and restricted mobility. Although diuretics are standard of care, they become ineffective, intolerable or exacerbate the problem in many patients. There are limited effective treatment options, resulting in poor clinical outcomes, high costs and a major impact on their quality of life. Sequana Medical is seeking to provide innovative treatment options for this large and growing "diuretic resistant" patient population. alfa pump® and DSR® are Sequana Medical's proprietary platforms that work with the body to treat diuretic-resistant fluid overload, and are intended to deliver major clinical and quality of life benefits for patients, while reducing costs for healthcare systems.
The Company received US FDA approval for the alfa pump System for the treatment of recurrent or refractory ascites due to liver cirrhosis in December 2024, following the grant of FDA Breakthrough Device Designation in 2019.
Results of the Company's RED DESERT and SAHARA proof-of-concept studies in heart failure published in European Journal of Heart Failure in April 2024 support DSR's mechanism of action as breaking the vicious cycle of cardiorenal syndrome. All three patients from the non-randomized cohort of MOJAVE, a US randomized controlled multi-center Phase 1/2a clinical study, have been successfully treated with DSR, resulting in a dramatic improvement in diuretic response and virtual elimination of loop diuretic requirements12. The independent Data Safety Monitoring Board approved the start of the randomized MOJAVE cohort of up to a further 30 patients, which is planned after alfa pump US PMA approval.
Sequana Medical is listed on the regulated market of Euronext Brussels (Ticker: and headquartered in Ghent, Belgium. For further information, please visit
