Brief Summary:
This study will evaluate the effectiveness of the drug valaciclovir in preventing transmission of genital herpes from an infected to an uninfected sexual partner Genital herpes is caused by the herpes simplex virus 2 HSV-2 or infrequently herpes simplex virus 1 HSV-1 Valaciclovir prevents the herpes virus from multiplying and may also reduce its transmission between partners
Couples 18 years of age and older in which one partner is infected with HSV-2 source partner and the other is not susceptible partner may be eligible for this study Candidates will be screened with blood tests for routine laboratory studies and to verify the presence or absence of HSV-2 or HSV-1 infection
Participants will give a medical history undergo a physical examination including genital examination and receive counseling on safer sex practices and how to recognize signs and symptoms of a possible first episode of genital herpes Source partners will also be counseled on transmission of genital herpes and susceptible partners will be interviewed about their sexual history and practices The source partner will be randomly assigned to take either a 500-mg tablet of valaciclovir or placebo a pill with no active ingredient daily for 8 months All participants will be given diary cards to complete for a month-the source partner will record any drug side effects and the susceptible partner will record any signs or symptoms of possible HSV infection
Participants will be seen in the clinic once a month for 8 months At these visits source partners will 1 return unused study medication and the completed diary card 2 discuss any adverse drug side effects experienced in the last month 3 review medications other than the study drug taken in the last month 4 undergo counseling on safer sex practices transmission of genital herpes and recognizing signs and symptoms of a first episode of genital herpes and 5 review symptoms and recurrences of genital herpes experienced during the last month During the final visit they will also provide a blood sample for routine testing and possible use in future studies Susceptible partners will 1 have a blood sample drawn for HSV testing 2 undergo safer sex counseling 3 review any symptoms experienced over the last month 4 be interviewed about sexual exposure and practices and 5 return the completed diary card
Source partners who have a recurrence of genital HSV while on the study will be asked to have their lesions cultured and will be offered open-label valaciclovir treatment Susceptible partners who contract genital herpes from the source partner during the study will have a genital examination to verify a fist episode of genital herpes and will receive 10 days of open-label treatment with valaciclovir Cultures will be taken from the mouth and genitals current medical conditions will be reviewed blood samples will be drawn on treatment days 1 and 10 and treatment side effects will be reviewed on days 5 and 10
At the end of the study infected partners will be offered a 12-month course of valaciclovir one 500-mg tablet daily Participants will be followed in the clinic once every 3 months to provide blood samples return unused study medication and the diary card discuss any drug side effects review medications taken besides the study drug and review symptoms or recurrences of genital herpes
All participants will be asked to complete a questionnaire for gathering information about people with genital herpes and people at risk for the infection

Detailed Description:
This is a randomized multicenter double-blind placebo-controlled Phase III study to evaluate the effect of valaciclovir in preventing the transmission of herpes simplex virus HSV in heterosexual couples discordant for the presence of herpes simplex type 2 virus HSV-2 antibody The seropositive source partner will be randomized to receive valaciclovir 500 mg once daily or placebo for 8 months and the susceptible seronegative partner will be monitored for clinical and subclinical serological acquisition of HSV Couples must be 18 years of age or older in general good health and in a monogamous relationship with each other Source partners must be seropositive for HSV-2 have a history of genital herpes recurrences and experiencing less than 10 recurrences per year and be off suppressive therapy upon entry into the study Susceptible partners must be HSV-2 seronegative The couple will be stratified based on gender and HSV status of the susceptible partner in a 2211 ratio HSV-1 negative female HSV-1 positive female HSV-1 negative male HSV-1 positive male They will then be randomized to either valaciclovir 500 mg once daily or placebo 11 randomization within each stratum The primary endpoint is the proportion of couples with clinical evidence of a first episode of genital HSV in the susceptible partner with laboratory confirmation Secondary endpoints will be time to clinical symptoms of genital HSV by the susceptible partner time to seroconversion in the susceptible partner and time to first recurrence of HSV in the source partner A total of 1500 couples will be randomized into the study Assuming a 3 incidence in the placebo arm and a reduction of 75 in the risk of showing clinical evidence of genital HSV this study will have at least 80 power for a two-tailed test at the 5 level of significance The safety and tolerance of valaciclovir will be assessed by laboratory evaluation and by occurrence and nature of adverse events The study will be conducted at approximately 35 outpatient centers in the United States Canada and Europe therefore it is expected that each center will enroll between 40 to 60 couples
