VGXI Enables Rapid GMP DNA Manufacturing Timeline for Geneos Therapeutics Personalized Cancer Immunotherapy

THE WOODLANDS,TX AND PLYMOUTH MEETING, PA – Leading plasmid DNA contract manufacturer VGXI, Inc. announced it has completed accelerated cGMP manufacturing of the first clinical batch of a personalized neoantigen vaccine for its client Geneos Therapeutics, Inc. Geneos is focused on developing DNA-based, neoantigen-targeting personalized cancer immunotherapies. Starting with receipt of seed plasmid DNA from Geneos, the VGXI team achieved a record-setting timeline of 5 days from host cell transformation to filled drug product manufacturing, and less than 2 weeks from transformation to release and shipment of the patient’s first dose. Overall, these timelines are a fraction of the 6 to 8 month turnaround time for GMP plasmid DNA that is standard in the industry, and they have been accomplished while maintaining the exceptional product quality for which VGXI is well known.

“Decades of experience and optimization of VGXI’s established, proprietary methods for DNA plasmid purification have allowed us to support the unique requirements of our client’s project.” Stated VGXI CEO Young Park. “This achievement represents the first personalized neoantigen vaccine product manufactured for Geneos’ clinical studies, and I am confident we will continue to deliver unparalleled product quality and rapid turnaround for subsequent patients as enrollment of the trial proceeds.”

VGXI’s efforts represent a critical element of Geneos’ integrated GT-EPIC™ platform. Geneos has established a broad collaboration created specifically to achieve the rapid biopsy-to-treatment turnaround times needed for personalized cancer therapies. The full GT-EPIC™ platform includes patient tumor exome/transcriptome sequencing and identification of the relevant neoantigen targets followed by neoantigen vaccine design, synthesis of the seed plasmid DNA, vaccine manufacture, and final delivery of the personalized neoantigen vaccine – with all platform elements executed within an overall timeline of 6 – 8 weeks. The patient specific GMP product lots manufactured under the VGXI supply agreement will support Geneos’ previously announced GT-30 clinical trial focused on the treatment of patients with advanced hepatocellular cancer.

Dr. Niranjan Y. Sardesai, Geneos’ Co-Founder, President & CEO said, “Achievement of rapid biopsy-to-treatment manufacturing turnaround times is an important differentiating milestone for the GT-EPIC™ platform in enabling these personalized treatments to be available faster for advanced cancer patients. We are pleased with our plasmid manufacturing partnership with VGXI in support of our GT-30 clinical trial. With their proven GMP manufacturing expertise, VGXI rose to the challenge and has enabled us to achieve our rapid manufacturing goals.”
