Herpes Simplex Type 1 Suppression in Hepatitis C (HSV1/HCV)

The purpose of this study is to examine the effects of valacyclovir in patients who have chronic hepatitis C, antibodies to herpes simplex type 1 infection but do not have antibodies to herpes simplex type 2 infection. Herpes simplex type 1 infection commonly causes cold sores or fever blisters, also known as herpes labialis, but most persons do not have any symptoms at all. Valacyclovir is a medication which is approved by the Food and Drug administration to treat herpes labialis. Valacyclovir has not been approved to treat chronic hepatitis C infection.

The study will take 16 weeks. Participants will be assigned to take either the study drug, valacyclovir, or a sugar pill that looks exactly like valacyclovir. The researchers and patients will not know which medication they are receiving. Study visits will occur every two weeks and will take approximately 30-45 minutes. All study visits will occur at the G.V. Sonny Montgomery VA Medical Center in Jackson, Mississippi.

    Measure change in HCV RNA viral load in treatment group as compared with placebo

Estimated Enrollment: 25
Study Start Date: April 2012
Estimated Study Completion Date: March 2015
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Valacyclovir 500 mg po bid
Drug: Valacyclovir
Valacyclovir 500 mg po bid
Placebo Comparator: 2
Matching placebo twice daily
Drug: Placebo
Placebo tablet twice daily

Detailed Description:

This is a randomized double-blind placebo-controlled clinical trial evaluating the effect of 500 mg valacyclovir twice daily on HCV viral load in HSV-1/HCV co-infected patients seronegative for HSV-2. Potential participants will be recruited from the Jackson VAMC viral hepatitis clinics. Eligible individuals will be invited to enroll in the study in a noncoercive manner. Study personnel will obtain full informed consent.

Using a computer generation randomization scheme, patients will be randomized 1:1 in blocks of 4 to receive valacyclovir 500 mg po twice daily or matching placebo. Patients will be counseled on the signs and symptoms of herpes labialis and genital herpes and complete a questionnaire to document medical/social history. Venipuncture will be performed every four weeks (i.e., at every other follow-up visit) to monitor complete blood cell count, liver function tests, serum levels of hepatitis C RNA and Herpeselect IgG HSV-2 ELISA. A de-identified baseline serum sample will be collected and stored in VA approved research space for future testing. At each visit, pill-count and tolerability of medications will be assessed. Patients will be asked about signs or symptoms of genital herpes. Data will be kept in a study chart labeled with the participant's coded study number in a locked office. Information from each study visit will be recorded into the chart by the PI or RA and entered into an encrypted database on a secure VA server. Baseline characteristics of the placebo and intervention group will be compared using appropriate parametric tests. HCV viral loads will be log10 transformed and analyzed using an intention to treat model.
