New drug trial aims to ease skin hardening in rare autoimmune disease
NCT ID NCT04789850
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether itacitinib is safe and effective for adults with systemic sclerosis, a disease that causes skin thickening and organ damage. About 74 participants with early or active disease will receive the drug or a placebo for one year. The main goal is to see if it reduces skin thickness, measured by a standard scoring method.
