Touchlight and Vanderbilt University Medical Center collaborate on DARPA Pandemic Prevention Platform programme to develop synthetic DNA-based antibody to protect against emerging threats

Touchlight, the leading synthetic DNA manufacturer, is collaborating with the Vanderbilt Vaccine Center (VVC) at Vanderbilt University Medical Center as part of the DARPA P3 programme.

The collaboration will explore the use of synthetic dbDNA to deliver antibody-based prophylaxis against pandemic disease threats. The aim is to make such therapies available in a significantly shorter timeframe by avoiding the long and costly large-scale production requirements of both conventional antibody-based treatments and plasmid DNA manufacture. Unlike vaccines, prophylactic antibodies have an immediate neutralising effect against the virus and may be able to act as a vaccine alternative or supplement whilst immunity builds.

Touchlight will develop and test a panel of novel dbDNA designs that encode for anti-Zika antibodies identified by Vanderbilt with the goal of boosting expression of the antibody to therapeutic levels. The project will also investigate a variety of delivery mechanisms including electroporation and targeted nanoparticles. The combination of these two aspects is aimed to deliver an improved expression profile in patients that enables rapid onset of protective levels of antibody.

Touchlight's unique synthetic DNA vector, brings multiple advantages over traditional plasmid DNA manufacture and other nucleic acid manufacturing techniques, including speed, reliability and scalability. Touchlight's dbDNA platform could unlock the potential for prophylactic nucleic acid launched antibodies, where the demands on rapid scale up to protect a population are equal or greater than those of vaccines.

Sarah Moore, Director of Gene Therapy Research at Touchlight said: "Antibody treatments can be the key to a swift pandemic response, if they can provide a good level of protection at short notice, until vaccines are available. We believe that the use of dbDNA to generate antibodies in vivo has the potential to significantly accelerate the availability of such therapies."

Robert Carnahan, Associate Director at the Vanderbilt Vaccine Center, said:

"The COVID-19 pandemic has made clear that the most significant bottleneck to rapid antiviral antibody therapeutics is the speed and scaling of manufacturing and delivery. Nucleic acid-delivered antibodies are a vital need in our pandemic fighting arsenal to directly address this bottleneck. Touchlight dbDNA's technology presents the possibility of addressing these pressing needs in therapeutic antibody manufacturing speed and scalability."

About Touchlight

Touchlight, based in London, UK, is the world's leading manufacturer of synthetic DNA. The company is pioneering enzymatic DNA production to enable the revolution in genetic medicines, including DNA and mRNA vaccines and cell and gene therapies. Touchlight has developed a novel, synthetic DNA vector known as "doggybone" or dbDNAtm.

dbDNAtm is a minimal, linear, covalently closed structure, that eliminates bacterial sequences. Touchlight's revolutionary enzymatic production platform enables unprecedented speed, scale, and the ability to produce genes with a size and complexity that is impossible with current technologies.

Touchlight is enabling companies across the genetic medicine industry. The company provides contract development and manufacturing capabilities to produce dbDNA as a critical starting material and active pharmaceutical ingredient for use in advanced therapies.
