ExThera and Asahi Kasei Medical secure exclusive distribution agreement in Japan

ExThera Medical and Asahi Kasei Medical, a core operating company of the Asahi Kasei Group, have entered into an exclusive distribution agreement in Japan for ExThera's Seraph® 100 Microbind® Affinity Blood Filter (Seraph 100). Per the agreement structure, ExThera Medical and Asahi Kasei Medical will collaborate to obtain regulatory approval of Seraph 100 for commercialization in Japan.

“The agreement with ExThera Medical is of great significance for the further expansion in the intensive care business field, positioned as one of our growth drivers,” said Shugo Sumiyoshi, President of Asahi Kasei Medical. “We believe the Seraph 100, with its unique adsorption capability, will add new value to our healthcare solutions and contribute to more lives saved.”

The Seraph 100 adsorber is the first blood purification device capable of removing a wide range of pathogens from the blood and has been used with more than 800 USA and European Union patients, in over 70 hospitals. It has demonstrated reduced mortality and ICU length of stay in severe/critically ill COVID-19 patients in preliminary clinical studies1,2. The device received European CE mark in 2019 for the treatment of bloodstream infections, and was granted use in 2020 for use in critically ill COVID-19 patients under FDA Emergency Use Authorization (EUA).

"ExThera’s partnership with Asahi Kasei Medical is an important milestone in our collaborative ongoing fight against life threatening pathogens. We are pleased to partner with the Japanese market leader in extracorporeal therapeutics who is motivated to commercialize Seraph 100 and join our global pursuit of saving lives of those suffering from severe sepsis/septic shock,” said Robert Ward, ExThera Medical Chairman and CEO.

About Seraph 100

As a patient's blood flows through the Seraph 100 filter, it passes over beads with receptors that mimic the receptors on human cells that pathogens target when they invade the body. Harmful substances are quickly captured and adsorbed onto the surface of the beads and are thereby removed from the bloodstream. Seraph targets the pathogens that cause the infection, while it also binds and removes harmful substances generated by the pathogen and by the body’s response to the infection. Seraph’s adsorption media (the beads) constitute a flexible platform that uses immobilized (chemically bonded) heparin for its well-established blood compatibility and its unique ability to bind bacteria, viruses, fungi, and important sepsis mediators reported to contribute to organ failure during sepsis. The ‘antithrombogenic’ heparin media can be combined with other ExThera-proprietary media to tailor the capability of future Seraph products for the treatment of specific diseases, or to further broaden Seraph’s capability.
