Summary

This trial tested the drug deucravacitinib in people with moderate-to-severe palmoplantar pustulosis, a skin condition causing painful pustules on the palms and soles. The study planned to enroll 25 participants who would take the drug daily for 16 weeks, but it was terminated early with only 3 participants. Researchers aimed to see if the drug could reduce pustules and improve quality of life.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Deucravacitinib
What this could lead to
If it works, this could point toward a new oral treatment option for palmoplantar pustulosis, a chronic skin condition with limited therapies.
What could go wrong
The trial was terminated early with only 3 participants, so results are very limited. It is a small, non-randomized study, and the drug may not prove effective or safe in larger groups.
