Pinpoint gene therapy: expanding the landscape of gene therapy
EG 427 is a French biotechnology company that pioneers a new approach in gene therapy called pinpoint gene therapy.
By exploiting the natural properties of Herpes Simplex Virus 1 (HSV-1), notably its ability to establish lifelong latency in peripheral neurons, EG 427 ensures highly specific and durable expression of the transgene to treat, in the long run, patients with severe, chronic and localized diseases, starting with peripheral nervous system disorders.
One year after its inception, EG 427 has already built its proprietary HSV-1 vector platform and achieved the preclinical proof of its concept in the most common type of neurogenic bladder (urinary bladder dysfunction due to supra-sacral spinal cord injury). Today, the company is evaluating the potential of pinpoint gene therapy in other indications that involve different compartments of the peripheral nervous system. The company expects to start its first clinical trials by 2023.
Based in Paris, EG 427 was founded by a world-renowned team in the field of HSV-1 vectorology and spinal cord injury-related disorders.

What Our scientific founder says
The wild-type HSV-1 virus has a number of unique features that are of interest for gene therapy. We have modified the virus to produce non-toxic HSV-1-based vectors that should support gene therapy for patients suffering from neurogenic detrusor overactivity. With a little tweaking we should also be able to extend the benefits of HSV-1-based gene therapy to other diseases of the peripheral nervous system and beyond.
