Aridis Pharmaceuticals Expands Patent Portfolio for Several Fully Human Monoclonal Antibodies Against Infectious Disease Targets
Date:2/24/2016

SAN JOSE, Calif., Feb. 24, 2016 /PRNewswire/ -- Aridis Pharmaceuticals, Inc., a biopharmaceutical company applying proprietary technologies to produce novel therapies for infectious diseases, announced today that in addition to the previously announced European Patent Office (EPO) patent issuance, the U.S. Patent and Trademark Office has issued Aridis' patent covering composition-of-matter, method of production and method of treatment for AR-301 (Salvecin™).

AR-301, a fully human monoclonal antibody (mAb) that neutralizes Staphylococcus aureus alpha-toxin, is currently being evaluated in a Phase 2a clinical trial across the U.S. and several countries in Europe.  AR-301 is being tested as an adjunctive therapy to standard of care antibiotics to treat hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP) and severe community-acquired pneumonia (CAP).  AR-301 was identified and developed through Aridis' propriety MabIgX™ technology by generating a hybridoma clone from B-cells of a recovered S. aureus bacteremia patient.  The antibody works by neutralizing S. aureus alpha-toxin, which is a critical factor involved in the establishment and persistence of S. aureus infection.

Additionally, the patents covering Aridis' human mAbs against the emerging Gram-negative bacterium Acinetobacter baumannii (A. baumannii), "AR-401," have also received notices of allowance in Europe and the U.S.

Vu Truong, Ph.D., Founder and Chief Executive Officer of Aridis, stated, "We are delighted to have successfully secured expanded patent protection for AR-301 and AR-401.  We are confident that the use of monoclonal antibodies to treat antibiotic resistant pathogens can have a broad impact on reducing healthcare costs by providing additional protection against infections.  The issuance of these patents adds to our already robust intellectual property estate covering our novel therapeutic antibodies, as well as our antibody discovery platform MabIgX®. Furthermore, significant progress has also been made toward the near-term allowance of patent application for Aridis' novel fully human monoclonal antibody against respiratory syncytial virus (RSV), AR-201."
