About Sequana Medical

Sequana Medical is a commercial stage medical device company utilizing its proprietary alfapump® and DSR® (Direct Sodium Removal) technologies to develop innovative treatments for fluid overload in liver disease, malignant ascites and heart failure where diuretics are no longer effective. Fluid overload is a frequent complication of many large diseases – including advanced liver disease driven by NASH (non-alcoholic steatohepatitis)-related cirrhosis and heart failure – with diuretic resistance being widespread. The U.S. market for the alfapump resulting from NASH-related cirrhosis is forecast to exceed €3 billion annually within the next 10-20 years. The heart failure market for DSR and the alfapump DSR® is estimated to be over €5 billion annually in the U.S. and EU5 by 2026.

The alfapump is Sequana Medical’s unique, fully implanted wireless device that automatically pumps fluid from the abdominal cavity into the bladder, where it is naturally eliminated through urination. DSR is Sequana Medical’s proprietary approach to managing sodium and fluid overload through use of a sodium-free infusate administered into the abdominal cavity.

In the U.S., the Company’s key growth market, the alfapump has been granted breakthrough device designation by the FDA for recurrent or refractory ascites due to liver cirrhosis. Interim data from the ongoing North American pivotal study (POSEIDON) showed positive outcomes against all primary endpoints and a rapid and persistent clinically important improvement in quality of life. All patients have been enrolled in the study and primary endpoint reporting is planned for Q4 2022. This study is intended to support a future marketing application of the alfapump in the U.S. and Canada. In Europe, the alfapump is CE-marked for the management of refractory ascites due to liver cirrhosis and malignant ascites and is included in key clinical practice guidelines. Over 900 alfapump systems have been implanted to date.

Sequana Medical has combined its proven alfapump and proprietary DSR therapy, and is developing the alfapump DSR, a breakthrough approach to fluid overload due to heart failure. RED DESERT demonstrated that repeated DSR therapy in diuretic-resistant heart failure patients is able to not only manage the fluid and sodium balance of these patients but also improve their cardio-renal status and restore their diuretic response for months post-treatment. Interim results from the ongoing SAHARA DESERT study of alfapump DSR in decompensated heart failure patients indicated a safe, effective and rapid elimination of persistent congestion and restoration of euvolemia, together with a considerable benefit in cardio-renal status and a dramatic improvement in diuretic responsiveness. Reporting of top-line data is planned for H2 2022.

Sequana Medical is headquartered in Ghent, Belgium. For further information, please visit www.sequanamedical.com.
