Can a single infusion stop GPP flares in their tracks?

NCT ID NCT06013969

First seen Nov 01, 2025

Summary

This study is testing whether the drug spesolimab can safely and effectively treat repeated flares of generalized pustular psoriasis (GPP), a serious skin condition. Adults with GPP who have had a flare will receive a single intravenous dose of spesolimab, with a possible second dose one week later. The main goal is to see if the treatment clears visible pustules within one week.
