Study summary

The aim of this study is to assess performance of using healthcare tools to understand genital Herpes Simplex Virus-2 (HSV-2) in patients ≥ 18 years of age in the United States and Europe.

More specifically, the study aims to evaluate patient-reported outcome and quality-of-life endpoints as well as the performance study procedures in a decentralised setting. Ultimately, this study will allow generating additional real-world evidence (RWE) on patterns of recurrences and other key parameters.

Study population

Patients will be recruited in specific community settings in the United States and in Europe. Screening logs will be used to assess participation rate.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Man or woman ≥18 years old.
  • Written obtained from the patient prior to performance of any study-specific procedure.
  • History of at least one episode of HSV-2 genital herpes lesions in the 12 months preceding the screening, and seropositive for HSV-2 as determined by Western blot OR PCR-positive for HSV-2 (newly diagnosed patients).
  • Patients who are medically stable in the opinion of the investigator.
  • Patients who, in the opinion of the investigator, are able to understand and comply with the study requirements (attend regular telephone calls/study site visits/home visits/self-completion of questionnaires, self-swabbing).
  • Seronegative for , as determined by laboratory testing. Patients documented to be positive to HIV will not be eligible for study participation

Exclusion criteria

Exclusion Criteria:

  • Prior receipt of a vaccine or candidate vaccine containing HSV antigens.
  • patients, as per medical history and investigator judgement.
  • Other genital tract disorders or sexually transmitted diseases that may interfere with the assessment of the study (as per investigator's judgement).
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

What researchers measure

Primary outcomes

  1. Number of patients with Polymerase Chain Reaction (PCR)-confirmed genital HSV-2 recurrences

    Genital HSV-2 recurrence is defined as presence of lesions in anogenital area (swelling, blisters, sores, crusts) and, a positive HSV-2 PCR test.

  4. Change in severity of symptoms during HSV-2 genital herpes recurrence assessed by Herpes outbreak impact (HOIQ) questionnaire

    Time frame: From the onset of recurrence until the end of the episode, assessed throughout the study period (for approximately 24 months)

  5. Impact of HSV-2 genital herpes recurrence on patients' daily functioning and quality-of-life as assessed by HSC questionnaire

    Time frame: From the onset of recurrence until the end of the episode, assessed throughout the study period (for approximately 24 months)

  6. Impact of HSV-2 genital herpes recurrence on patients' daily functioning and quality-of-life as assessed by HOIQ questionnaire

    Time frame: From the onset of recurrence until the end of the episode, assessed throughout the study period (for approximately 24 months)

  7. Impact of HSV-2 genital herpes recurrence on patients' daily functioning and quality-of-life as assessed by EuroQoL-5 dimension (EQ-5D) health questionnaire

    Time frame: At Enrolment Visit (Day 1) and at Day 1 of each PCR-confirmed recurrence

  8. Long-term impact on the quality-of-life of patients with symptomatic HSV-2 genital herpes as assessed by Recurrent genital herpes quality-of-life (RGHQoL) questionnaire

    Time frame: At Enrolment Visit (Day 1) and every 3 months until study completion at Month 24

  9. Long-term impact on the quality-of-life of patients with symptomatic HSV-2 genital herpes as assessed by short form-12 questionnaire

    Time frame: At Enrolment Visit (Day 1) and every 3 months until study completion at Month 24

  10. Number of self-swabs collected during genital HSV-2 recurrences throughout the study period

    Time frame: Throughout the study period (from Day 1 up to Month 24)

  11. HSV-2 PCR self-swab results

    Time frame: At first genital HSV-2 recurrence, assessed throughout the study period (for approximately 24 months)

  12. HSV-2 PCR investigator swab results

    Time frame: At first genital HSV-2 recurrence, assessed throughout the study period (for approximately 24 months)

  13. Number of patients reporting genital HSV-2 recurrences by using eDiary

    Time frame: Throughout the study period (from Day 1 up to Month 24)

  14. Number of patients reporting genital HSV-2 recurrence during the 3 monthly calls with the investigator

    Time frame: Throughout the study period (from Day 1 up to Month 24)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 7, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
