Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to test the safety and effectiveness of two experimental therapeutic vaccines against herpes simplex virus, type 2 (HSV-2).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a dose escalation study to evaluate the safety, immunogenicity, and efficacy of 3 doses of HSV plasmid DNA (pDNA) vaccines formulated with Vaxfectin® in subjects with a minimum of 1 year of reported history of genital herpes, and either 2 to 9 recurrences within the year prior to screening, or 2 to 9 recurrences per year prior to starting suppressive therapy.
