Flat Wart

The goal of this clinical trial is to learn if injecting acyclovir (an antiviral drug) or vitamin D3 directly into skin warts works to clear them in people aged 12 and older with common, plantar, flat, or periungual (around the nail) warts. The main questions it aims to answer are: 1. Does intralesional acyclovir or vitamin D3 lead to complete clearance of warts by week 8? 2. Which treatment clears warts more effectively? 3. What side effects do participants have with each treatment? Researchers will compare acyclovir injections (Group A) to vitamin D3 injections (Group B), with 20 participants in each group, to see which treatment works better at clearing warts. Participants will: 1. Receive an injection directly into the wart every 2 weeks for up to 4 sessions 2. Have photographs taken of their warts before treatment and at each visit 3. Visit the clinic for checkups where the size and number of warts will be measured 4. Be followed for up to 3 months to check for wart recurrence and side effects

Human papillomavirus (HPV) infection is very common, as most people will experience infection during their lifetime. The most common manifestation of HPV infection is common warts. Common warts may appear at any age. Conventional treatments can be used to treat warts and they are based on two mechanisms: stimulation of cellular immunity against HPVs or destruction of the lesion. These treatments are based on the location of the wart and the degree of the symptoms. No specific antiviral therapy is available to cure warts and today, there is no treatment that allows the definitive eradication of the virus. The 2LVERU® has been available for more than 20 years, and has received a marketing authorization in Belgium by the Federal Agency for Medicines and Health Products (FAMHP). It is used as an immune regulator in the treatment of common warts (verruca vulgaris), flat warts (verruca plana) or plantar warts (verruca plantaris) caused by Human Papillomavirus. Since 2LVERU® has been made available, clinical observational data collected on treated patients have shown the beneficial effect on the disappearance of warts. The purpose of this placebo-controlled, randomized, double-blind trial is the comparison of the efficacy of the treatment on the disappearance of warts at the end of treatment (6-month visit) between the 2LVERU® JUNIOR and 2LVERU® versus the placebo group.
