Is this trial a fit for you?

Probably not a fit

Patients who do not exhibit fatigue or related symptoms of EBV infection may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to assess the efficacy of two investigational drugs, 2LEBV® and 2LXFS®, in alleviating asthenia associated with Epstein-Barr Virus (EBV) infections. Participants aged 12 and older who have experienced fatigue for over a month and exhibit additional symptoms related to EBV will be enrolled. The treatment involves taking one capsule per day in a sequential order for a total of ten days, with a placebo group for comparison. The study seeks to provide a potential therapeutic option for managing symptoms of EBV infections, which currently lack effective treatments.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients suffering from fatigue related to EBV infections.

How similar studies have gone: While there is limited data on the specific drugs being tested, the approach of targeting symptoms of EBV infections has been explored in other studies, though this specific methodology is relatively novel.
