Altimmune Announces Notice of Allowance on Patent Covering Use of NasoShield in the U.S.

Jan 23, 2018

Patent Will Specifically Cover Prophylactic and Post-Exposure Use of NasoShield in the U.S.

Patents with Similar Protection Already Issued in Europe and Japan

GAITHERSBURG, Md., Jan. 23, 2018 (GLOBE NEWSWIRE) -- Altimmune, Inc. (Nasdaq:ALT), a clinical-stage immunotherapeutics company, today announced that it has received a Notice of Allowance from the United States Patent and Trademark Office (US PTO) for patent application No. 14/870,570, “Targets and Compositions for Use in Decontamination, Immunoprophylaxis, and Post-Exposure Therapy Against Anthrax” (‘570 patent).  The ‘570 patent claims extend the IP coverage for NasoShield by the intranasal administration route.  The Company has already been granted patents extending IP protection for intranasal administration of NasoShield in Europe and Japan.

Anthrax vaccines can be used as General Use Prophylactics (GUP) to establish immunity to anthrax disease prior to exposure to the pathogen, or as a Post-Exposure Prophylactic (PEP) for use with antibiotic therapy following exposure to the pathogen.  The ‘570 patent covers NasoShield in both the GUP and PEP setting.

“We continue to protect our technology through strategic intellectual property achievements and this Notice of Allowance is an important addition to our IP portfolio,” said Bill Enright, President and Chief Executive Officer of Altimmune. 

Altimmune’s NasoShield anthrax vaccine candidate is being developed as the ultimate anthrax vaccine. NasoShield is based on the Company’s RespirVec technology to provide protection following a single intranasal administration as opposed to multiple injections. Based on head-to-head results from studies performed in gold-standard preclinical models, NasoShield provided more rapid and persistent protection when compared to the currently approved anthrax vaccine, both potential key advantages for presumed use in a bioterrorism emergency.

The Company’s anthrax vaccine candidates are being developed with support from the United States Government Department of Health and Human Services.  NasoShield is being developed with the support of the Biomedical Advanced Research and Development Authority under contract HHSO100201600008C.
