Summary
Brief summary
The purpose of this first-time-in-human (FTiH) study is to evaluate the reactogenicity,
safety, immune response, and efficacy of an investigational herpes simplex virus
(HSV)-targeted immunotherapy (TI). The study will be conducted in 2 parts: Part I assessing
different formulations of the Herpes Simplex Virus-targeted immunotherapy (HSVTI) in healthy
participants aged 18-40 years; Part II assessing the 2 formulations of the HSVTI in
participants aged 18-60 years with recurrent genital herpes.
