EASL Congress is one of the world’s premier events dedicated to liver health, bringing together physicians, scientists, and allied health professionals from across the globe to share knowledge and highlight breakthroughs across the full spectrum of hepatology. The poster, titled “Recompensation of decompensated cirrhosis and long-term resolution of ascites in patients undergoing alfapump placement: experience from the multi-centre POSEIDON study,” was presented in the Portal Hypertension session. The alfapump is a subcutaneous implantable device that automatically and continuously moves ascites fluid from the abdominal cavity into the bladder, where it is eliminated naturally, freeing patients from dependence on repeated large-volume paracentesis procedures. Of 48 subjects with a functioning alfapump at six months post-implant, 10 achieved recompensation, with a median time to recompensation of 519 days. Key markers of recovery, including declining MELD-Na (Model for End-Stage Liver Disease-Sodium, a standard measure of liver disease severity) scores and rising serum albumin, differentiated those who recompensated from those who did not. Both the Recompensation group (n = 10) and those with Ongoing Decompensation (n = 38) experienced similar post-implant improvements in ascites complaints (Ascites-Q). These findings are preliminary and further data collection is ongoing. Dr. Ethan Weinberg, Associate Professor of Clinical Medicine at the University of Pennsylvania, presenter of the poster and co-investigator on the POSEIDON study, commented: “These findings challenge the assumption that decompensated cirrhosis is an irreversible state. We are seeing objective signals including declining MELD-Na, improving albumin, and sustained resolution of ascites, suggesting that a meaningful proportion of patients may achieve recompensation through long-term ascites control with the alfapump. It is particularly meaningful to see these findings emerge from the POSEIDON study as we are implanting patients with the alfapump commercially at the University of Pennsylvania, bringing this technology directly to the patients who need it.” Dr. Gijs Klarenbeek, Chief Medical Officer of Sequana Medical, added: “By removing the burden of ascites continuously and automatically, we are seeing that the alfapump may create the conditions for patients to recover nutritional status and liver function in ways that have not previously been possible. The similar improvement in quality of life in patients from both the Recompensation and the Ongoing Decompensation groups, as evidenced through the improvement in the Ascites-Q score, demonstrates the important benefits from alfapump implantation in all POSEIDON patients. These clinical findings from our pivotal study come at an exciting time as adoption of the alfapump continues to grow across leading US centers.” The alfapump system received U.S. FDA Premarket Approval in December 2024 for the treatment of recurrent or refractory ascites due to liver cirrhosis. It is the first and currently only U.S.-approved active implantable medical device (Class III) that automatically and continuously removes ascites from the abdomen into the bladder. In August 2025, CMS approved the New Technology Add-on Payment for the alfapump when performed in the hospital inpatient setting, effective October 1, 2025.

It is indicated for the removal of excess peritoneal fluid from the peritoneal cavity into the bladder, where it can be eliminated through normal urination. Contraindications: MRI Safety Information: The alfapump® System is MRI unsafe. This diagnostic procedure is contraindicated due to possible movement of the alfapump®, damage to the pump circuitry, tissue damage in the vicinity of the alfapump® and/or catheter dislocation. Hyperbaric oxygen therapy is contraindicated because the environmental conditions entailed in this therapy are out of the defined range of use for the alfapump® System. Warnings, Risks, and Precautions: The implantation of the alfapump® may result in infection that could delay liver transplant or impact transplant listing status. Additional risks associated with implanting the alfapump® System including risk of peritoneal cavity infections/peritonitis, Coagulopathy, Small bladder capacity and/or obstructive uropathy. The following procedures or therapies could impact the alfapump® System function: Supersonic therapy and high-frequency heat therapy, Transcutaneous Electrical Nerve Stimulation (TENS), Lithotripsy, Defibrillation, Radiation therapy, Electrocautery, or use of other implantable medical devices and wearable devices. Adverse Events: In addition to procedure related risks the following Adverse Events may occur: pump pocket hematoma, skin erosion, infection, pump migration, catheter clogging or other catheter complications resulting in tissue damage or loss of or change in therapy, genito-urinary complications, reduced kidney function, hepatic encephalopathy, progression of liver disease, and other systemic effects. Caution: the law restricts the sale by or on the order of a physician. Refer to package insert provided with the product for complete Instructions for Use, Contraindications, Potential Adverse Effects, Warnings and Precautions prior to using this product. The alfapump® System is currently not approved in Canada. DSR® therapy is still in development and is currently not approved in any country. The safety and effectiveness of DSR® therapy has not been established.

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. alfapump® 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 alfapump 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. In Sequana Medical’s POSEIDON study, a landmark study across 18 centers in the US and Canada, the pivotal cohort of 40 patients implanted with the alfapump showed at 6 and 24 months post-implantation the virtual elimination of therapeutic paracentesis and an improvement in quality of life.2,3 Sequana Medical is commercializing the alfapump through a specialty commercial team initially targeting US liver transplant centers – 90 of these centers perform more than 90% of US liver transplants annually. In August 2025, CMS announced that it approved the New Technology Add-on Payment for the alfapump when performed in the hospital inpatient setting as of October 1, 2025. 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 requirements.4 The independent Data Safety Monitoring Board approved the start of the randomized MOJAVE cohort of up to a further 30 patients, which is dependent on securing additional financing. Sequana Medical is listed on the regulated market of Euronext Brussels (Ticker: SEQUA.BR) and headquartered in Ghent, Belgium.
