Applied DNA Subsidiary LineaRx and Takis/Evvivax Progress Linear DNA for Use as Cancer Vaccine Candidates
Collaboration to study antigen-specific immune responses aimed at achieving therapeutic effects
STONY BROOK, N.Y., March 1, 2019 – Applied DNA Sciences Inc. (NASDAQ: APDN) (“Applied DNA”), a leader in large-scale PCR-based DNA manufacturing, announced today that LineaRx, Inc. (“LineaRx”), its wholly-owned subsidiary focused on next-generation biotherapeutics, will ship TK7 and ConTRT amplicons to Takis/Evvivax next week as part of the companies’ Joint Development Agreement (“JDA”) entered into in September 2018.
Per the JDA, LineaRx and Takis/Evvivax will jointly develop linear DNA expression amplicons for TK7 and ConTRT, two of Takis/Evvivax’s anti-cancer vaccine candidates, utilizing LineaRx’s validated linear DNA technology. Linear DNA amplicons carrying the DNA sequences for Takis/Evvivax vaccine candidates will be delivered to pre-clinical animal models via Takis/Evvivax’s proprietary electroporation technology.
In 2018, LinearRx and Takis/Evvivax’s collaboration showed immunogenicity in mice that were vaccinated with linear DNA against the human protein telomerase that is over-expressed in more than 85% of all cancers. “This year we are using ConTRT, an improved version of our telomerase vaccine and a unique personalized approach which includes an epitope-prediction pipeline and a delivery strategy to achieve an extremely effective cancer vaccine over what has been done previously,” said Dr. Luigi Aurisicchio, CEO of Takis/Evvivax. “Each expression amplicon will undergo rigorous quality subject matter testing, immunogenicity testing, followed by a tumor challenge, with results planned for publication later this year.”
“Our collaborations with Takis/Evvivax and other therapy developers are helping to validate LineaRx’s novel technology as a viable alternative to bacterially-produced plasmids, with the potential for increased patient safety and reduced costs, using new quality control protocols for large-scale PCR production at LineaRx. We believe that linear DNA and the establishment of new quality attributes for this new therapeutic field will change the way gene and immune therapies will be performed,” stated Dr. James Hayward, president and CEO of Applied DNA. “Our implementation of testing for new quality attributes will support our preparation to approach FDA to seek approval for clinical study. Our know-how in the fields of therapeutic linear DNA production and the standardized PCR platforms in use at LineaRx enable us to create novel expression amplicons. We are extremely pleased with the progress we are making with Takis/Evvivax under our JDA.”

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.
