VGXI, Inc., a leading provider of DNA plasmid manufacturing and development services, announced today that it has successfully scaled-up and completed two large-scale cGMP fermentation runs using Nature Technology Corporation’s (NTC) HyperGRO™ fermentation system, including their antibiotic-free selection vector. VGXI has been able to achieve reproducible plasmid yields of up to 1.8 g/L at the 320L scale, the largest fermentation scale yet using the HyperGRO™ technology.

VGXI entered into a manufacturing agreement with Coridon Pty Ltd earlier this year to manufacture Coridon’s Herpes Simplex Virus 2 DNA vaccine for their upcoming Phase I clinical trial. Coridon requested VGXI use HyperGRO™ fermentation technology to satisfy their project’s unique requirements.

The data will be presented on a collaborative poster at the DNA Vaccines Conference to be held December 5-7, 2012 in San Diego, CA.
