Is this trial a fit for you?

Likely a good fit

People aged 12 years and older with clinically diagnosed common, plantar, flat, or periungual warts who are not pregnant, not immunocompromised, and have not had topical or destructive wart treatment in the prior three months.

Probably not a fit

Pregnant or lactating people, immunocompromised individuals, those with infected warts, or anyone with known hypersensitivity to vitamin D3 or acyclovir are excluded and would not be expected to benefit from participating.

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

What this trial studies

People with common, plantar, flat, or periungual warts will be assigned to receive intralesional injections of either acyclovir or vitamin D3, with 20 participants in each group. Injections are given every two weeks for up to four sessions, with photographs and measurements of wart size and number taken at each visit. The primary outcome is complete clearance of warts by week 8, and participants are followed for up to three months to monitor recurrence and side effects. Safety and local adverse reactions will be recorded and compared between the two groups.

Why it matters

Potential benefit: If one injection treatment proves more effective and well tolerated, it could provide a simple clinic-based option to clear warts faster and reduce recurrence.

How similar studies have gone: Intralesional vitamin D3 has shown positive results in prior small studies for wart clearance, while intralesional acyclovir is less well studied and represents a relatively novel approach in this setting.
