About alfapump in recurrent or refractory ascites due to liver cirrhosis
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. If approved by the FDA, the alfapump could become 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.
The PMA application submitted to the US FDA was 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 alfapump. The primary effectiveness endpoints at six months post-implantation in the Pivotal Cohort[ii] exceeded the predefined thresholds with statistical significance, and primary safety endpoint data was in line with expectations[iii]. Data at 12 months post-implantation continued to show a strong and durable clinical profile, virtually eliminating the need for therapeutic paracentesis and delivering a clinically meaningful improvement in patients’ quality of life[iv].
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 alfapump vs standard paracentesis procedures and that the safety profile of the alfapump is comparable to standard of care.
The North American market of recurrent and refractory ascites due to liver cirrhosis is forecast to grow on average 9% per year, from approximately 78,000 patients in 2025 reaching 147,000 patients by 2032, primarily driven by the increasing prevalence of NASH[v]. The total market opportunity for alfapump is estimated at $2.4 billion in 2025, including approximately $600 million from the Company’s initial priority market targeting patients requiring at least 12 paracentes per year. To date, over 1,000 alfapump systems have been implanted.
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, untolerable 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, delivering major clinical and quality of life benefits for patients and reducing costs for healthcare systems.
The Company’s Premarket Approval (PMA) application for the alfapump was submitted to the US FDA in December 2023 and accepted for substantive review in January 2024, having reported positive primary and secondary endpoint data from the North American pivotal POSEIDON study in recurrent or refractory ascites due to liver cirrhosis.
Results of the Company’s RED DESERT and SAHARA proof-of-concept studies in heart failure 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. 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 alfapump US PMA approval.

Important Regulatory Disclaimers
The alfapump® system is currently not approved in the United States or Canada. In the United States and Canada, the alfapump system is currently under clinical investigation (POSEIDON Trial) and is being studied in adult patients with refractory or recurrent ascites due to liver cirrhosis. DSR® therapy is still in development and it should be noted that any statements regarding safety and efficacy arise from ongoing pre-clinical and clinical investigations which have yet to be completed. There is no link between DSR therapy and ongoing investigations with the alfapump system in Europe, the United States or Canada.
