Genital Herpes (HSV) Medication Study

Genital Herpes (HSV) Medication Study

The University of Washington is seeking volunteers for an investigational HSV-2 medication trial. The purpose of this clinical trial is to test an investigational HSV-2 medication to determine its safety and effects in the body.

The study will enroll participants who have a history of recurrent genital HSV-2. Participants will be randomized to receive either investigational medicine or placebo. Participants must be willing to stop the use of episodic or suppressive antiviral therapy to treat HSV symptoms for a 42-day period during the study.

The trial will last around 3 months and will involve a minimum of 11 in-person visits. Study visits will involve physical exams and blood draws. As part of the study, participants will also be asked to collect anogenital swabs twice a day for a 28-day period and to complete daily symptom
diaries. At two of the study visits, participants will need to stay at the clinic for 8 hours for repeat blood draws, about once an hour.
