Could a psoriasis drug help thickened hands and feet?

NCT ID NCT06561321

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a daily cream called tapinarof, already used for psoriasis, in 6 adults with palmoplantar keratoderma — a condition that causes painful thickening of skin on the palms and soles. Researchers want to see if the cream can clear or improve the skin and check for side effects. It's a small, early-phase trial at Indiana University.

What this could lead to
If it works, this could point toward a new topical treatment for palmoplantar keratoderma, a rare skin condition with limited options.
What could go wrong
This is a very small early-phase trial with only 6 participants, so results may not apply to everyone. The drug may not work or could cause side effects.
