Gene editing to durably control genital herpes (HSV-2)
Meganuclease-mediated gene editing for durable control of HSV-2 infection
This project uses a harmless AAV virus to deliver specialized gene-cutting enzymes aimed at removing latent HSV-2 from nerve cells in adults with genital herpes.

What this research studies
I have genital herpes and this project tries to remove the virus hiding in nerve cells using engineered enzymes called meganucleases delivered by adeno-associated virus (AAV). Researchers will pick and optimize an HSV-2-specific meganuclease in lab tests and evaluate delivery and activity in preclinical models. The team builds on earlier work that removed most latent HSV-1 in animals and will adapt and test the approach for HSV-2. This Phase I STTR focuses on designing a safe, specific AAV-based gene-editing therapy as a step toward future human trials.
Who could benefit from this research
Good fit: Ideal candidates would be adults (21+) with recurrent genital HSV-2 infection who are interested in a potential one-time gene-based approach to reduce recurrence and transmission.
Not a fit: People who only have HSV-1, are under 21, are pregnant, or have contraindications to viral-vector gene therapies may not benefit from or be eligible for this work.
Why it matters
Potential benefit: If successful, this approach could substantially reduce or eliminate latent HSV-2 in nerve cells, lowering outbreaks and the risk of transmission.
How similar studies have performed: Related AAV-delivered meganuclease work eliminated up to 97% of latent HSV-1 DNA in animal models, but applying this gene-editing approach to HSV-2 and to humans is novel and untested.
