FREEHOLD, N.J., Aug. 12, 2020 (GLOBE NEWSWIRE) -- Avalon GloboCare Corp. (NASDAQ: AVCO) (Avalon or The Company), a clinical-stage global developer of cell-based technologies and therapeutics, announced today that Avalon has expanded and filed two provisional patents with the U.S. Patent and Trademark Office outlining compositions and methods of developing a decoy cytokine receptor-based filter system to treat cytokine storms. These provisional patent applications are direct results of recent advancements related to Avalons AVA-Trap therapeutic program. The technology utilizes cytokine receptorFc-fusion proteins to potentially serve as an antibody-like decoy to dampen the excessive cytokine release that occurs during hyper-activation of the immune systema life-threatening condition called cytokine storm that can cause multi-organ failure and death.

Patients infected with the SARS-CoV-2 virus that causes COVID-19 are susceptible to developing cytokine storms, which occur when the immune system suddenly produces high levels of inflammatory proteins called cytokines that concentrate in the blood. The extracorporeal hemo-purifier device is designed to provide potential treatment for patients experiencing cytokine storms induced by COVID-19, hepatitis, HIV, influenza, graft-versus-host disease, and cytokine release syndrome associated with CAR-T cell therapy.

The expanded patent application was jointly filed with Professor Shuguang Zhang of the Massachusetts Institute of Technology (MIT) Media Lab, and Professor Uwe Sleytr, a full member of the Austrian Academy of Sciences and pioneer of applied surface layer (S-layer) nanotechnology.

The application combines Avalons AVA-Trapprogram with two innovative technologies. The first is the QTY code protein design platform, which was developed together with Professor Shuguang Zhangs laboratory at MIT. This technology platform can turn water-insoluble proteins that normally reside within cellular membranesand that can be difficult to work within the laboratoryinto water-soluble proteins that can be used in many clinical applications. The second technology is applied S-layer nanotechnology, based on the repetitive protein structures that make up the outer surface of microbial cells. Coating of S-layers on solid surfaces can greatly enhance the binding orientation and efficiency of targeted ligand proteins that are directed to bind to, and capture, molecules of choice in the blood.

Together, Avalon is developing these unique technologies to advance an extracorporeal hemodialysis and hemo-purification device consisting of membrane protein receptors for specific cytokines coated onto an S-layer-based matrix that can be used to specifically filter out cytokines responsible for a cytokine storms in patients experiencing this immune system attack on the body, including patients with COVID-19.

While non-specific blood filtration systems exist, the clinical AVA-Trapblood filtration system would specifically target cytokine storm-causing proteins, allowing the detection and recovery of cytokinesand serving as a potential clinical therapy as well as a diagnostic tool. Importantly, it is the Companys goal to develop a filtration system that can be customized to trap only specific molecules.

We are grateful for our strong scientific partnerships that enabled the rapid speed with which we are developing this novel clinical tool, stated David Jin, M.D., Ph.D., President and Chief Executive Officer of Avalon. This medical device holds enormous promise as it directly addresses a leading cause of mortality for patients with illnesses that make them vulnerable to the damaging effects of a cytokine storm, added Dr. Jin.
