Applied DNA Subsidiary, LineaRx, Inc., Signs Joint Development Agreement with Takis and Evvivax to Develop Linear-DNA Based Anti-Cancer Vaccines
Collaboration Seeks to Develop PCR-produced Linear DNA as a Safer Expression Vector for Vaccines
STONY BROOK N.Y., September 20, 2018 – Applied DNA Sciences Inc. (NASDAQ: APDN) (“Applied DNA” or the “Company”) announced today that LineaRx, Inc. (“LineaRx”), its wholly-owned subsidiary focused on next-generation biotherapeutics, has signed a Joint Development Agreement (the “Agreement”) with Takis S.R.L. and Evvivax S.R.L. (“Takis/Evvivax”), biotechnology companies focused on the discovery and development of DNA based anti-cancer vaccines for the human and animal markets, respectively.
Under the terms of the Agreement, LineaRx and Takis/Evvivax will jointly develop linear DNA expression vectors for two of Takis/Evvivax’s anti-cancer vaccine candidates utilizing LineaRx’s linear DNA technology. Linear DNA amplicons carrying the DNA sequences for Takis/Evvivax vaccine candidates will be delivered to preclinical animal models via Takis/Evvivax’s proprietary electroporation technology. Antigen-specific immune responses aimed at achieving therapeutic effects will be studied.
The previously announced collaboration between the companies has already shown promise of yielding immunity in mice that were DNA-vaccinated against the human protein telomerase, which is over-expressed in more than 85% of all cancers.
Dr. Luigi Aurisicchio, CEO of Takis/Evvivax stated: “We are excited to co-develop linear DNA expression vectors for our DNA vaccine candidates with LineaRx. Initial data from the use of LineaRx’s amplicons in our vaccine candidates is promising. The advantages of linear DNA over plasmids would provide a clear market edge over plasmid-based DNA sources. We look forward to a mutually beneficial collaboration”.
“This Agreement serves to validate LineaRx’s technology as critical and necessary to the field of biotherapeutics in its ability to deliver potentially powerful approaches to the treatments of chronic diseases,” stated Dr. James Hayward, president and CEO of Applied DNA. “Takis/Evvivax are ideal partners of LineaRx given their innovative anti-cancer vaccine candidates for both humans and animals together with their expertise in preclinical animal models.”
Dr. Hayward continued, “The use of PCR-produced linear DNA, as opposed to bacterially produced plasmids, is an innovative concept that provides the potential for increased patient safety, ease of manufacture and vaccine logistics, and reduced costs. Our know-how in the fields of bulk linear DNA production and in bioconjugate chemistry enable us to create novel and highly efficient expression vectors.”
With their stability at room temperature, low risk of infection or secondary illness, and stability during transportation, DNA vaccines overcome many of the undesirable properties of conventional vaccines. The global DNA based human vaccine market is expected to grow at a CAGR of 55% and reach a value of $2.7 billion by 20191. The global veterinary vaccine market is expected to reach $20.6 billion by 20212, with DNA based animal vaccines gaining rapid market share.
Takis/Evvivax emerged from a Merck-supported research center in Rome and has relationships across Big Pharma (http://www.takisbiotech.it/en/takis-services). The companies have agreed to seek sponsorship for their work together.
LineaRx seeks to commercialize the biotherapeutic value of Applied DNA’s deep expertise and experience in the design, manufacture and chemical modification of DNA by large scale polymerase chain reaction (“PCR”). Linear DNA is a form of DNA distinct from the circular form of DNA most commonly produced in plasmids and grown in bacteria. Plasmids are extrachromosomal DNA found in bacteria and are associated with the genes for antibiotic resistance which are often exchanged between bacteria and consequentially, are seen by many to embody a serious threat to global health. In addition, many nucleic acid-based therapies also rely on viral vectors for efficient transfection and expression of plasmid DNA. These viral vectors carry additional nontrivial risks and are extremely time consuming and expensive to manufacture.
In all forms of gene therapy, DNA exerts its influence from within the nucleus. Recombinant events for circular DNA are permanent and alter the genomes of the affected cells and their progeny. The fundamental challenge of all gene and cellular therapies is safety. Recent studies have elaborated “unintended consequences” when plasmid and viral vectors are combined that may pose future risks for treated patients.
When linear DNA enters the nucleus, it does not need to be incorporated into the genome in to be temporarily expressed as the intended proteins product. LineaRx posits that for the effectiveness of genetic vaccines or genetic immune therapies, transient expression may be sufficient.
