Summary

This study tested whether injections of Candin, a yeast extract, can clear common warts better than a placebo. 330 people aged 12 and older with 3 to 20 warts received injections every two weeks until their wart disappeared. The goal was to see if Candin leads to complete wart clearance and how long that takes.

What this could mean

Active substance: Candin (yeast extract injection)
What this could lead to: If it works, Candin could offer a new, non-invasive treatment option for stubborn common warts.
What could go wrong: This is a completed Phase 3 trial, but results are not yet published. Warts may not clear, or the effect may be small compared to placebo.
