France-based Eyevensys SA has raised $12 million from a syndicate led by Korea Investment Partners to accelerate development of its preclinical programme, EYS809, for treating wet age-related macular degeneration. The Series B round extension was also supported by existing investors. The Eyevensys technology is a non-viral gene therapy delivery platform that uses an electrotransfection system to deliver DNA plasmids encoding therapeutic proteins into the eye.
