Incyte to Present New Data Highlighting Progress Across its Dermatology Pipeline at the European Association of Dermatology and Venerology 2025 Congress

- 24-week data from the Phase 3 STOP-HS clinical trial program of povorcitinib in patients with hidradenitis suppurativa (HS) selected as a late-breaking oral presentation

Today Incyte (Nasdaq:INCY) announced that it will present new data from its dermatology portfolio at the European Association of Dermatology and Venerology (EADV) 2025 Congress, held from September 17 – 20, in Paris. Highlights include late-breaking, oral and poster presentations featuring data for povorcitinib (INCB054707), an oral small-molecule JAK1 inhibitor, and ruxolitinib cream (Opzelura^®), a topical JAK1/2 inhibitor.

“Our presence at EADV demonstrates the significant progress across our dermatology portfolio. The late-breaking data from the STOP-HS clinical trial program reinforce the potential of povorcitinib to benefit patients impacted by hidradenitis suppurativa (HS), a challenging and debilitating immune-mediated dermatologic condition,” said Pablo J. Cagnoni, M.D., President and Head of Research and Development, Incyte. “Data on ruxolitinib cream in new patient populations continues to demonstrate safety and efficacy in individuals with atopic dermatitis (AD), vitiligo and prurigo nodularis (PN). We look forward to advancing these studies, and to providing additional treatment options for patients.”

Opzelura (ruxolitinib) cream, a novel cream formulation of Incyte’s selective JAK1/JAK2 inhibitor ruxolitinib, approved by the U.S. Food & Drug Administration for the topical treatment of nonsegmental vitiligo in patients 12 years of age and older, is the first and only treatment for repigmentation approved for use in the United States. Opzelura is also approved in the U.S. for the topical short-term and non-continuous chronic treatment of mild to moderate atopic dermatitis (AD) in non-immunocompromised patients 12 years of age and older whose disease is not adequately controlled with topical prescription therapies, or when those therapies are not advisable. Use of Opzelura in combination with therapeutic biologics, other JAK inhibitors, or potent immunosuppressants, such as azathioprine or cyclosporine, is not recommended.
