About the POSEIDON study

POSEIDON is a single-arm, open-label, within-subject crossover study of the alfapump in patients with recurrent and refractory ascites due to liver cirrhosis in approximately 20 centres across the US and Canada. The study consisted of a Pivotal Cohort for primary endpoint analysis and an additional Roll-In Cohort for new centers to become familiarized with the implantation procedure before they enrolled patients in the Pivotal Cohort. Pivotal Cohort patients entered into a three-month pre-implant observation period in which they received standard of care therapy (consisting of therapeutic paracentesis (TP)) before the alfapump was implanted.

Pivotal Cohort patients met all pre-specified primary effectiveness endpoints with statistical significance at six months post-implantation, including i) 100% median per-patient reduction in TP post- vs pre-implantation (p<0.001), vs hypothesis of at least a 50% reduction and ii) 77% of patients with at least 50% reduction in number of TP post- vs pre-implantation (p<0.001), vs hypothesis of at least 50% of patients. Primary safety endpoint data, including the rate of alfapump-related re-interventions adjudicated by the Clinical Events Committee, were in line with expectations with no unanticipated adverse device effects.

Patients are 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 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. 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, difficulty breathing and restricted mobility that severely impacts daily life. Although diuretics are standard of care, the problem is that in many patients they are no longer effective and / or tolerable. There are limited effective treatment options for these patients, 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 has reported positive primary endpoint data from the North American pivotal POSEIDON trial of the alfapump in recurrent or refractory ascites due to liver cirrhosis, enabling the filing of a Pre-Market Approval (PMA) application with the FDA, planned for H2 2023. Having delivered clinical proof-of-concept for DSR as a disease-modifying drug program for the treatment of heart failure, the Company will commence MOJAVE, a US randomized controlled multi-center Phase 1/2a clinical trial of DSR 2.0, with initial data expected in Q4 2023.

Sequana Medical is listed on Euronext Brussels (Ticker: SEQUA.BR) and headquartered in Ghent, Belgium. For further information, please visit www.sequanamedical.com.

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 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.
