NCT04065971

Brief Summary

Herpes simplex virus (HSV) infection is very common, as most people will experience herpetic infection during their lifetime. The most common manifestation of HSV infection is sores which may appear at any age. No specific antiviral therapy is available to totally cure herpetic infections and today, there is no treatment that allows the definitive eradication of the virus. The 2LHERP® has been available for more than 20 years, and has received a marketing authorization in Belgium by the FAMHP. It is used as an immune regulator in the treatment of herpetic infections. Since 2LHERP® has been made available, clinical observational data collected on treated patients have shown the beneficial effect on the disappearance of herpetic recurrences. The purpose of this placebo-controlled trial is to evaluate the efficacy of 2LHERP® on the treatment of herpetic infections in adults.

Outcome Measures

Primary Outcomes (1)

  • Evaluation of the efficacy of 2LHERP® on the reduction of the number of recurrent orofacial herpes episodes at 12 months.

    The primary objective of the study will be to evaluate the change from baseline within the number of episodes of herpes infections observed for 12 months, where the baseline value is the number of episodes experienced within the 12 months preceeding study enrolment.

    12 months

Secondary Outcomes (9)

  • Remaining herpes infection recurrence free 12 months after treatment initiation (yes/no)

    12 months

  • Remaining herpes infection recurrence free 6 months after treatment initiation (yes/no)

    6 months

  • Number of episodes of herpes infection observed at 6 months

    6 months

  • Time to first recurrence of herpes infection during the treatment

    6 months

  • Mean duration of episodes, the duration for a given episode being defined as the number of days between the start of the episode and the last day before all symptoms recorded as 'none' for 2 consecutive days, in the patient diary

    12 months

  • +4 more secondary outcomes

Interventions

The treatment schema consists in taking the content of one capsule a day, 15-30 minutes before breakfast, on an empty stomach, sequentially, according to capsules' numerical order: 1 through 10. When capsule number 10 is taken, capsule 1 of the next blister should be taken on the next day to continue the treatment. The duration of treatment will be 6 months of continuous intake of the content of 1 capsule/day.
