  • Sequana Medical announces positive outcome of Day 100 meeting with FDA regarding PMA application for alfapump®
  • Positive and collaborative meeting with FDA
  • PMA substantive review complete; No further new questions on clinical or pre-clinical data

Ghent, Belgium – 22 May 2024– Sequana Medical NV (Euronext Brussels: SEQUA) (the “Company” or “SequanaMedical“), a pioneer in the treatment of fluid overload in liver disease, heart failure and cancer, today announces the agreed outcome of the “Day 100” meetingi with the US Food and Drug Administration (FDA), following receipt of the “Day 90” major deficiency Letter. The alfapump is the Company’s fully implantable, wirelessly charged device for patients with recurrent or refractory ascites due to liver cirrhosis and received breakthrough device designation from the US FDA in 2019.

The PMA application for the alfapump system, which was based on the successful execution of Sequana Medical’s pivotal POSEIDON study, was accepted for substantive review on 29 January 2024. Following a review of this application by the FDA, the Company received a “Day 90” major deficiency letter and a “Day 100” meeting was held with FDA to align on key findings. The FDA confirmed completion of the substantive review and no further new questions on the clinical study or the pre-clinical data, unless related to the Company’s response to the “Day 90” Letter. The FDA had a number of non-clinical questions that require additional work and the Company currently anticipates to submit this additional information by the end of September 2024. In light of the FDA’s feedback and the rapidly evolving cybersecurity environment, the Company intends to exclude RPMS/DirectLink (the software for remote uploading of performance data from the alfapump) from the PMA application and the initial alfapump commercialisation, and to submit a next-generation version in a PMA supplement post-approval.

The Company now forecasts FDA approval before the end of Q1 2025, with no change to the planned US commercial launch in H2 2025. The Company continues to evaluate its financing options to achieve FDA approval and prepare for commercial launch of the alfapump.

Timur Resch, Global Vice President QM/QA/RA at Sequana Medical, commented: “The receipt of the PMA Day 90 letter and completion of the Day 100 meeting is another huge milestone for Sequana, and reflects the significant amount of work by the team for the preparation of the marketing application. We appreciate the positive interaction with the FDA and believe that the outstanding questions are manageable. We intend to complete these activities in time for a response to the FDA by the end of Q3 this year.”

Ian Crosbie, Chief Executive Officer of Sequana Medical, commented: “We are very pleased with the progress of our alfapump PMA application and grateful for the collaborative nature of discussions with the FDA for our breakthrough device. The completion of the substantive review and confirmation there will be no further new questions related to the clinical study data or pre-clinical data, unless related to our responses, is a very important event for us, providing clarity on the approval path forward and derisking the alfapump program. We look forward to addressing the remaining questions from FDA and anticipate approval before the end of Q1 2025.”

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 Cohortii exceeded the predefined thresholds with statistical significance, and primary safety endpoint data was in line with expectationsiii. 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 lifeiv.

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 NASHv. 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. US market approval of the alfapump is anticipated before the end of Q1 2025 with US commercial launch planned for H2 2025.

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.

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

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.
