What this trial studies
This clinical trial aims to assess the efficacy of 2LHERP®, an immune regulator, in reducing the frequency of recurrent orofacial herpes infections in adults. The study will involve 140 participants aged 16 to 80 who have experienced six or more episodes of herpes in the past year. Participants will be randomly assigned to receive either 2LHERP® or a placebo for six months, followed by a six-month follow-up period. The primary objective is to evaluate the reduction in the number of herpes episodes over 12 months, alongside secondary objectives focusing on various aspects of treatment efficacy and safety.
Why it matters
Potential benefit: If successful, this treatment could significantly reduce the frequency of painful herpes outbreaks, improving patients' quality of life.
How similar studies have gone: While 2LHERP® has been used for over 20 years, this specific placebo-controlled trial is novel in its structured evaluation of its efficacy.
