Varicella-zoster virus (VZV) causes chickenpox and shingles, while herpes simplex virus (HSV) is responsible for oral and genital herpes. Although current treatments mainly focus on inhibiting viral replication, there is a critical need for new therapies to address the limitations and side effects associated with existing treatments.

EG 427 SAS has closed a €27 million (US$28.3 million) series B round, which will fund it to completion of the first clinical trial of the lead gene therapy program, opening the way for its herpes simplex viral-vectored products to be developed in a range of chronic neuro-urology disorders.

Researchers from Excision Biotherapeutics Inc. and affiliated organizations have reported the development of a novel CRISPR/Cas9-mediated genome editing therapy – EBT-104 – for the treatment of latent herpes simplex virus 1 (HSV-1) keratitis.

Half of the individuals with genital herpes simplex virus (HSV) infection experience several recurrence episodes per year, especially if the causative agent is HSV type 2 (HSV-2). Standard-of-care viral DNA polymerase inhibitors are not fully effective in preventing recurrences and managing symptoms.

Gilead Sciences Inc. and Assembly Biosciences Inc. have entered into a 12-year partnership to advance the research and development of novel antiviral therapies, with an initial focus on Assembly’s established areas of herpesviruses, hepatitis B virus (HBV) and hepatitis D virus (HDV).
