With fewer new antibiotics being developed, and the continuing emergence of new drug-resistant pathogens, ExThera’s sorbent hemoperfusion device should become an important new tool for critical care clinicians,” said Bob Ward, CEO, ExThera Medical.

BERKELEY, Calif.–(BUSINESS WIRE)–June 24, 2014–

ExThera Medical Corporation announced today that U.S. Patent No. 8,758,286 has been issued to the Company relating to its Seraph® Microbind® Affinity Blood Filter (Seraph). ExThera Medical also announced that it has listed an executive summary of its business at www.HealthiosXchange (H/X), an equity-based portal for accredited investors that raises funds under Rule 506 (b).

This key patent for ExThera Medical provides methods to engineer and manufacture ‘biomimetic’ devices that treat bloodstream infections quickly and safely. The main ingredient used to capture pathogens is heparin that is permanently bound to a substrate with high surface area.

“This is an important patent for ExThera, covering the therapeutic use of immobilized heparin in an extracorporeal device, to quickly remove dangerous bacteria, viruses, and toxins from whole blood. In addition, it covers the use of our ‘mixed media’ invention that combines the broad-spectrum binding of immobilized heparin with ‘supplemental adsorbents’, to remove even more pathogens and toxins, while retaining the desirable anticoagulant properties of the heparin surface,” said Bob Ward, CEO of ExThera Medical.

Seraph is designed to be the device equivalent of a very broad spectrum anti-infective drug, with the added benefit that bacteria removal by Seraph doesn’t release dangerous toxins into the patient’s bloodstream. In fact, when Seraph is used together with antibiotics, it may improve outcomes by scavenging the toxins released by pathogens killed by the drugs.

According to the World Health Organization (WHO), the world is heading for the post ‘anti-biotic era.’ Both the U.S. and Europe’s Centers for Disease Control (CDC) have released reports warning of the emergence of drug-resistance and the urgent need to address this global problem. So far little is being done. As an example, despite treatment with antibiotics, the reported mortality rate in patients with Carbapenem-Resistant Enterobacteriaceae (CRE) bloodstream infections is more than 50%.

ExThera has demonstrated in vitro efficacy of this patented technology by removing 5 different pathogens that are classified as ‘urgent’ or ‘serious’ by the US CDC. Additional in vitro studies have also shown efficient removal of many other bacteria, toxins, viruses, and fungi from blood. The Seraph Microbind Technology may be the only near-term solution to combat drug resistant infections.

“Once proven in upcoming clinical trials and approved for sale, Seraph has the potential to become a ‘blockbuster device’, based on the clinical need for preventing bloodstream infections from progressing to sepsis and septic shock. This is especially important when the infection is caused by drug-resistant bacteria like MRSA and ‘CRE Superbugs.’ No other therapy-drug or medical device-is designed to be as effective as Seraph® in removing a broad array of pathogens and toxins from the blood of bacteremic and viremic patients,” said Dr. Ward.

About ExThera Medical Corporation

Privately held ExThera Medical, based in Berkeley, Calif., is targeting the clinical treatment of blood-borne diseases including bacteremia, as well as the removal of harmful substances present in banked human blood. While medical treatments of bacteremia, e.g., caused by S. aureus or MRSA (Methicillin-Resistant S. aureus) usually rely on antibiotics, ExThera Medical’s Seraph® device capitalizes on the affinity of bacteria to attach to immobilized heparin within the device-a natural anticoagulant, that has many other biological attributes. Seraph® is designed to be a biomimetic adjunct to antibiotic therapy that reduces bacterial load and the duration of bacteremia, thereby potentially preventing complications such as endocarditis, osteomyelitis, and a systemic inflammatory response. The Company introduced its Seraph device concept to clinicians earlier this year at the annual congress of the Society for Critical Care Medicine.

CAUTION: ExThera Medical’s Seraph® device is not cleared by the FDA for distribution in the United States.
