New pill aims to calm lupus skin flares in major trial
NCT ID NCT07332481
First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 5 times
Summary
This study tests an experimental pill called enpatoran for people with lupus who have active skin rashes. About 202 participants will receive either the drug or a placebo for 24 weeks, while continuing their usual treatments. The goal is to see if enpatoran can significantly reduce skin disease activity. This is a Phase 3 trial, meaning it is one of the final steps before possible approval.
