Which eczema drug wins? a Head-to-Head test aims to find out
NCT ID NCT06937788
First seen Aug 28, 2026 · Last updated Aug 28, 2026
Summary
This trial compares two approved eczema drugs, upadacitinib and dupilumab, in people with moderate-to-severe atopic dermatitis. Researchers will measure how well each drug clears the skin and improves quality of life, including itch and sleep. The study aims to confirm earlier findings that upadacitinib may work faster, while also checking patient-reported outcomes. Participants will receive either a daily upadacitinib pill or a dupilumab injection every other week.
