Applied DNA Biotherapeutics Subsidiary LineaRx and EvviVax Publish Additional Positive Animal Proof-of-Concept Data Supporting LinearDNA™ Platform as a Unique Approach to Veterinary DNA Vaccine Development


– Separately, LineaRx Announces Successful Expression In Vitro of Vaccine Candidate Encapsulated with Lipid Nanoparticles –

STONY BROOK, NY, July 25, 2022–(BUSINESS WIRE)–Applied DNA Sciences, Inc. (NASDAQ: APDN) (the “Company”), a leader in cell-free, enzymatic DNA production, today announced the publication of a manuscript containing data demonstrating that a linearDNA vaccine successfully elicited neutralizing antibodies and cellular immunity against SARS-CoV-2. The manuscript, authored by LineaRx, the Company’s majority-owned biotherapeutics subsidiary, and LineaRx’s development partner, EvviVax, SRL, further establishes the utility of the LinearDNA (“linDNA) platform as a large-scale enzymatic production approach to prophylactic and therapeutic veterinary vaccine applications.

The manuscript, “A Linear DNA Vaccine Candidate Encoding the SARS-CoV-2 Receptor Binding Domain Elicits Protective Immunity in Domestic Cats,” is available in preprint on bioRxiv and will be submitted for peer-reviewed publication. It details positive data showing safety and immunogenicity of a linDNA vaccine candidate against SARS-CoV-2 in a cohort of family-owned cats. Prime-boost vaccinations were administered by electro-gene transfer intramuscularly to the cohort, which induced robust, protective neutralizing antibodies and cellular immune responses.

Separately, LineaRx announced the successful expression in vitro of its linDNA SARS-CoV-2 vaccine candidate encapsulated within lipid nanoparticles (LNP). The linDNA-LNP vaccine, designed and manufactured at the Company’s Stony Brook, New York facility, will be used in upcoming live animal studies to assess the performance of linDNA-LNP vaccines and will inform the final design of the Company’s lead veterinary asset, a linDNA-LNP canine lymphoma vaccine candidate.

“Veterinary DNA vaccines are an exciting opportunity for us and this existing data further substances that linDNA is well-suited and efficacious for animal prophylactic and therapeutic vaccines. Further, when viewed alongside our positive LNP studies, we believe that a linDNA-LNP product has the strong potential to offer enhanced ease of administration and improved clinical outcomes,” stated Dr. Hayward, president and CEO of Applied DNA and LineaRx. “These data, together with other data generated by LineaRx over the past 24 months, have been invaluable in better understanding the performance of the linDNA platform for vaccine applications and have guided the design of our canine lymphoma vaccine candidate, for which we are currently identifying out-licensing animal health partners should our planned clinical trial meet all endpoints and gain USDA APHIS conditional approval.”

Added Dr. Luigi Aurisicchio, CEO of Evvivax SRL, “The results of this study confirm the potency of the genetic design and technology of our vaccines. SARS-CoV-2 is a zoonotic disease and finding a way to protect pets from infection may contribute to reduce viral reservoir and spreading.We believe that fully synthetic, linear DNA is a great platform providing gene therapy and enhanced vaccine products in short time for the prevention and the cure of many diseases.”

About LineaRx, Inc.

LineaRx, an Applied DNA Sciences, Inc. (NASDAQ: APDN) company, was formed in 2018 to commercialize the parent company’s 20+ years of experience in polymerase chain reaction (‘PCR’)-based DNA manufacturing and leadership in enzymatic DNA production.

LineaRx is developing and commercializing the LinearDNA™ platform as a cell-free enzymatic platform for the large-scale DNA manufacture of high-fidelity DNA sequences for use in nucleic acid-based therapeutics.

DNA manufactured via the platform is free of adventitious DNA sequences and can be chemically modified to optimize DNA for specific applications, offering compelling advantages over plasmid DNA in many biotherapeutic applications, from mRNA and DNA vaccines to redirected cell and gene therapies.
