About this study

Official title: A Randomized, Cross-Over Study to Evaluate the Suppressive Effect of High-Dose Valacyclovir Versus Once Daily Valacyclovir on Herpes Simplex Virus Type 2 Genital Shedding in Herpes Simplex Virus-2 Seropositive Adults

On 13 August 2008, this trial was submitted to ClinicalTrials.gov as modification to NCT00362297. On 28 April 2011, the two records were split for administrative purposes and each trial was given its own unique study record. Please refer to the "History of Changes" on posting NCT00362297 for a detailed summary of the modifications.

The purpose of the research study is to evaluate the effectiveness of high-dose valacyclovir compared to once daily valacyclovir for reduction of asymptomatic HSV-2 genital shedding in persons with genital herpes.

Read more

The study will enroll men and women who are 18 years or older, test positive to HSV-2 (by blood test) and have had a first outbreak of HSV-2 within the past 6 months or have had at least 4 genital herpes outbreaks in the past year. Participants must be HIV negative and willing to stop taking suppressive therapy for HSV for the one week wash out period. (Females only: You must not be pregnant or breast-feeding). Both men and women will be asked to use an effective form of birth control.

Involvement in the study will last 11-weeks and you will be asked to visit the clinic every 2-weeks. At each visit, you will be given medication to take daily (either once daily valacyclovir or high dose valacyclovir; you will receive both medications at some point during this study). We will ask you to give a blood sample for liver, kidney and blood count testing at each visit. There will be a total of 8 study visits and each visit will last approximately 30 minutes. We will ask that you complete a daily symptom diary and collected daily home swabs 4-times a day, everyday during the study. Each daily home swab will take less than 3 minutes to perform.

Screening Assessment

Patients will be assessed for their eligibility to enter the study at a screening visit. After signing informed consent they will undergo a medical history and the following information will be recorded in the Case Report Form (CRF):

  • Demographic Data: Date of birth, sex, marital status, education and race
  • Previous antiviral medication taken
  • History of sexually transmitted infections and sexual history.
  • Women of childbearing potential will undergo a urine pregnancy test. Serologic samples for HSV-2 and HIV will be obtained. Part of the blood sample will also be used for safety labs.

Start of Study Visit (Day 0) and Day 14, 28, 35, 42, 56, 70, and 77 Follow-Up Visits.

Eligible patients will return to clinic to be given study drug and a patient diary card on which to record concomitant medications, signs and symptoms, and adverse experiences. The investigator will instruct the patient on daily home viral sample collection, taking the study drug, and completing the diary card. The patient will be instructed to return to clinic in 2 weeks, +/- 2 days. Medication compliance will be assessed at each visit using pill counts. Safety labs will be performed on day 14, 28, 35, 56, 70 and 77.

Crossover Study Visit Prior To Washout Period (Day 35-41)

Participants will not be given study drug or placebo during the 7-day washout period. Participants will not be required to obtain swabs during the washout period.

Daily Home Viral Sample Collection

Participants will collect swabs from the genital mucosa four times per day and store the samples in PCR media with preprinted labels. Women will swab the cervicovaginal, vulvar and perianal areas, and men will swab the penile and perianal. Every two weeks, they will return the samples to the Virology Research Clinic when they present for additional study drug and assessment.

Final Study Visit (Day 77)

At the final study visit at Day 77 or for premature discontinuation, the investigator will perform the activities at the regular study visits, with the exception of the dispensation of study drug.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Frequency of HSV-2 Total Shedding From the Genital Tract as Measured by PCR, Calculated Using a Per-day Shedding Rate in Participants Treated With High-dose Valacyclovir as Compared to Once-daily Valacyclovir.

    Measured: 11 weeks

Secondary outcomes (3)
  1. Quantity of HSV Detected, Median

    Median quantity of HSV detected, among swabs with any HSV detected

    Measured: 11 weeks

  2. Number of Genital HSV Shedding Episodes

    The number of HSV shedding episodes. A shedding episode is defined as any number of positive swabs preceded and followed by 2 negative swabs.

    Measured: 11 weeks

  3. Duration of Genital HSV Shedding Episodes

    Median duration of HSV shedding episodes, in hours, among episodes of known duration

    Measured: 11 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing valacyclovir in people with Genital Herpes, run by University of Washington at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Mar 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Frequency of HSV-2 Total Shedding From the Genital Tract as Measured by PCR, Calculated Using a Per-day Shedding Rate in Participants Treated With High-dose Valacyclovir as Compared to Once-daily Valacyclovir. (time frame: 11 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01346475, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Mar 2017.
