A new gene therapy company has been launched in the US and UK by a group of academic-entrepreneurs who aim to treat genetic diseases of the eye with therapies delivered by a herpes simplex virus (HSV) vector. The company, Eudora, plans to employ an HSV-1 vector as a delivery vehicle instead of the commonly used adeno-associated virus (AAV) vector. In an announcement on 31 October, Eudora said its HSV vehicle could deliver more drug than an AAV vector, one of the most widely used virus vectors in the industry.
