Incyte Announces New Data from Phase 3b TRuE-AD4 Trial of Opzelura ® (Ruxolitinib Cream) in Adults with Moderate Atopic Dermatitis

Incyte (Nasdaq:INCY) today announced new data from the Phase 3b TRuE-AD4 study evaluating the efficacy and safety of Opzelura^® (ruxolitinib cream) in adults with moderate atopic dermatitis (AD) who had an inadequate response, intolerance or contraindication to topical corticosteroids (TCSs) and topical calcineurin inhibitors (TCIs). These data will be presented during the Systemic and New Therapies for Atopic Dermatitis session on Sunday, October 26 at 10:55 a.m. AEDT (Saturday, October 25 at 7:55 p.m. ET) (Abstract #1177) at the 15th Georg Rajka International Symposium on Atopic Dermatitis (ISAD), held from October 24 – 26, 2025, in Melbourne.

Data from TRuE-AD4, which build on previously announced topline results, show the study met its co-primary endpoints at Week 8, with a statistically significant proportion of patients achieving both a ≥75% improvement in Eczema Area and Severity Index (EASI75) score from baseline (70.0% with Opzelura vs. 18.5% with vehicle, P<0.0001) and Investigator's Global Assessment Treatment Success (IGA-TS; 61.3% vs. 13.6%; P<0.0001). Patients treated with Opzelura demonstrated improvement in EASI75 (43.8% vs. 3.7%, nominal P<0.0001) and IGA-TS (29.4% vs. 2.5%, nominal P<0.0001) at Week 2. More patients treated with Opzelura achieved both EASI75 and IGA-TS at Week 8 than vehicle (59.4% vs. 13.6%; nominal P<0.0001).

“The TRuE-AD4 data further reinforce the safety and efficacy profile of Opzelura and its ability to control key signs and symptoms of moderate AD, including improvement in bothersome symptoms like itch,” said Jim Lee, M.D., Group Vice President, Inflammation & Autoimmunity, Incyte. “These data will support the filing of a Type-II variation application for ruxolitinib cream 1.5% (Opzelura) in Europe, as we seek to meet the needs of more patients around the world who require nonsteroidal topical treatments for moderate AD.”

Additional key findings from the TRuE-AD4 study include:

• Improvement in itch as measured by a ≥4-point improvement in Itch Numeric Rating Scale (NRS4) score.
  • Nearly two-thirds (62.5%) of patients treated with Opzelura achieved Itch NRS4 by Week 8 (vs. 19.8% with vehicle, P<0.0001).
  • There was significant improvement in worst daily itch at Day 2 with 29.1% of patients treated with Opzelura achieving Itch NRS4 vs. 14.3% with vehicle (P=0.0072; by multiple imputation).
  • Current Itch NRS4 was also measured at 15 minutes (16.4% with Opzelura vs. 7.7% with vehicle).
• Improved Patient-Oriented Eczema Measure (POEM) and Dermatology Life Quality Index (DLQI) scores:
  • More patients treated with Opzelura vs. vehicle achieved a POEM score 0–2 (clear or almost clear) at Week 8 (39.7% vs. 8.6%).
  • Patients treated with Opzelura showed a mean DLQI score improvement at Week 8 (from 19.3 to 4.3 with Opzelura vs. 19.1 to 10.7 with vehicle).
• Opzelura was well tolerated with no serious infections, major adverse cardiovascular events (MACE), malignancies or thromboses reported during the 8-week vehicle-controlled period. The most common treatment-related adverse event observed in the Opzelura arm was application site acne (4.4% vs 0% in vehicle arm).

“TRuE-AD4 offers compelling support for the utility of Opzelura for patients with moderate AD who have limited treatment options due to inadequate responses or intolerances to TCS and TCI-based topical therapies, who may otherwise be recommended for systemic therapy,” said Dr. Andreas Wollenberg, Professor of Dermatology and Allergy, Augsburg University Hospital, Germany. “AD is a challenging, chronic condition and I believe that these data reinforce Opzelura as an important therapeutic option.”

Atopic dermatitis (AD) – the most common type of eczema –is a chronic, recurring, inflammatory and highly pruritic skin condition that affects up to 25% of children and up to 12% of adults worldwide, with an estimated prevalence among adults of 5.5% across 27 European countries.^{1,2,3,4,5,6,7} Signs and symptoms include irritated and itchy skin that can cause red lesions that may ooze and crust.

About TRuE-AD4
TRuE-AD4 (NCT06238817) is a randomized, double-blind, vehicle-controlled Phase 3b study designed to evaluate the efficacy and safety of Opzelura^® (ruxolitinib cream) in adults with moderate atopic dermatitis (AD). The study enrolled 241 patients (≥18 years old) who meet the specific inclusion criteria, including an Investigator's Global Assessment (IGA) score of 3 and an Eczema Area and Severity Index (EASI) score greater than 7 at both screening and Day 1 and who have AD on 10% to 20% of their Body Surface Area (BSA; excluding scalp). Patients also had to have a documented history of inadequate response, intolerance or contraindication to topical corticosteroid (TCS)s and topical calcineurin inhibitor (TCI)s within the 12 months prior to the screening visit.

Patients were randomized 2:1 to receive Opzelura administered twice daily (BID) or vehicle (non-medicated cream) BID.

The co-primary endpoints of TRuE-AD4 are the proportion of patients achieving IGA Treatment Success (IGA-TS), defined as an IGA score of 0 (clear) or 1 (almost clear) with at least a two-point improvement from baseline, and EASI-75, defined as ≥75% improvement in EASI score, at Week 8. Key secondary endpoints include the proportion of patients with a ≥4-point improvement in Itch Numeric Rating Scale (NRS4) score at various time points. Other exploratory endpoints include the proportion of patients who achieved IGA-TS, NRS4, EASI-75, a decrease from baseline in the affected body surface area (%BSA), change from baseline in the skin pain NRS score, EASI90 and more, measured at various time points. The study also tracked the frequency, duration and severity of adverse events associated with the use of ruxolitinib cream.

IMPORTANT SAFETY INFORMATION

OPZELURA is for use on the skin only. Do not use OPZELURA in your eyes, mouth, or vagina.

OPZELURA may cause serious side effects, including:

Serious Infections: OPZELURA contains ruxolitinib. Ruxolitinib belongs to a class of medicines called Janus kinase (JAK) inhibitors. JAK inhibitors are medicines that affect your immune system. JAK inhibitors can lower the ability of your immune system to fight infections. Some people have had serious infections while taking JAK inhibitors by mouth, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have been hospitalized or died from these infections. Some people have had serious infections of their lungs while taking OPZELURA. Your healthcare provider should watch you closely for signs and symptoms of TB during treatment with OPZELURA.

OPZELURA should not be used in people with an active, serious infection, including localized infections. You should not start using OPZELURA if you have any kind of infection unless your healthcare provider tells you it is okay. You may be at a higher risk of developing shingles (herpes zoster) while using OPZELURA.

Increased risk of death due to any reason (all causes): Increased risk of death has happened in people 50 years of age and older who have at least 1 heart disease (cardiovascular) risk factor and are taking a medicine in the class of medicines called JAK inhibitors by mouth.

Cancer and immune system problems: OPZELURA may increase your risk of certain cancers by changing the way your immune system works. Lymphoma and other cancers have happened in people taking a medicine in the class of medicines called JAK inhibitors by mouth. People taking JAK inhibitors by mouth have a higher risk of certain cancers including lymphoma and lung cancer, especially if they are a current or past smoker. Some people have had skin cancers while using OPZELURA. Your healthcare provider will regularly check your skin during your treatment with OPZELURA. Limit the amount of time you spend in the sunlight. Wear protective clothing when you are in the sun and use a broad-spectrum sunscreen.

Increased risk of major cardiovascular events: Increased risk of major cardiovascular events such as heart attack, stroke, or death have happened in people 50 years of age and older who have at least 1 heart disease (cardiovascular) risk factor and taking a medicine in the class of medicines called JAK inhibitors by mouth,especially in current or past smokers.

Blood clots: Blood clots in the veins of your legs (deep vein thrombosis, DVT) or lungs (pulmonary embolism, PE) can happen in some people taking OPZELURA. This may be life-threatening. Blood clots in the vein of the legs (deep vein thrombosis, DVT) and lungs (pulmonary embolism, PE) have happened more often in people who are 50 years of age and older and with at least 1 heart disease (cardiovascular) risk factor taking a medicine in the class of medicines called JAK inhibitors by mouth.

Low blood cell counts: OPZELURA may cause low platelet counts (thrombocytopenia), low red blood cell counts (anemia), and low white blood cell counts (neutropenia). Your healthcare provider may do a blood test to check your blood cell counts during your treatment with OPZELURA and may stop your treatment if signs or symptoms of low blood cell counts happen.

Cholesterol increases: Cholesterol increase has happened in people when ruxolitinib is taken by mouth. Tell your healthcare provider if you have high cholesterol or triglycerides.
