Majority of Individuals with Atopic Dermatitis Improved with Arcutis’ Roflumilast Cream 0.15% According to New Data from Phase 3 Program

• Individual patient response data highlight 91.5% of individuals treated with roflumilast cream had a measurable improvement in Eczema Area and Severity Index (EASI) in just 4 weeks
• 85% achieved measurable improvement by Week 1 (the earliest timepoint measured)
• Data presented at the 2024 Winter Clinical Dermatology Conference – Hawaii

WESTLAKE VILLAGE, Calif., Jan. 14, 2024 (GLOBE NEWSWIRE) — Arcutis Biotherapeutics, Inc. (Nasdaq: ARQT), a commercial-stage biopharmaceutical company focused on developing meaningful innovations in immuno-dermatology, today announced new individual patient response data showing the vast majority of individuals (91.5%) treated with investigational roflumilast cream 0.15% had a measurable improvement in Eczema Area and Severity Index (EASI) in 4 weeks. New pooled analyses from two pivotal Phase 3 studies (INTEGUMENT-1 and INTEGUMENT-2) were presented at the 2024 Winter Clinical Dermatology Conference – Hawaii held January 12-17, 2024, in Honolulu, HI. Roflumilast cream 0.15% is a once-daily, steroid-free cream being investigated for adults and children 6 years of age and older with atopic dermatitis.

At Week 4, a statistically significant greater percentage of patients achieved a 50% reduction in EASI scores (EASI-50), with 69.2% of patients treated with roflumilast cream compared to 44.4% of those treated with vehicle (p<0.0001) based on observed data. At the same 4-week endpoint, a 75% reduction in EASI scores (EASI-75) was achieved in 44.5% of roflumilast-treated patients compared to 21.2% of vehicle-treated patients (p<0.0001). Importantly, EASI-90 was observed in 22.4% of patients treated with roflumilast cream compared to 8.6% of vehicle-treated patients (p<0.0001) and a 100% reduction (EASI-100) was observed in 9.8% of patients treated with roflumilast cream compared to 4.8% of vehicle-treated patients (p<0.002).

“These individual patient response data can give confidence to clinicians that roflumilast cream can provide predictable and effective improvement of atopic dermatitis, with 70% of adults and children achieving EASI-50 and nearly one in four achieving 90% or greater improvement in eczema area and severity. If approved, the consistent efficacy with daily application over a four week period combined with a tolerability and safety profile without limitations on body regions or duration treated will make this a great addition for management of pediatric and adult atopic dermatitis,” said Lawrence Eichenfield, MD, chief of pediatric and adolescent dermatology at Rady Children’s Hospital-San Diego, professor of dermatology and pediatrics and vice-chair of the department of dermatology at UC San Diego School of Medicine, and study investigator.

“These data demonstrate the rapid and reliable efficacy of roflumilast cream in atopic dermatitis with the majority of individuals achieving measurable improvement in EASI in as little as one week,” said Patrick Burnett, MD, PhD, FAAD, chief medical officer of Arcutis. “We are pleased to be able to share these individual response data with the wider dermatology community and develop a better understanding about the consistent clinical response to roflumilast cream for patients with atopic dermatitis.”

Roflumilast cream 0.15% safety and tolerability data were comparable with vehicle, with low rates of application site adverse events (AEs), treatment-related AEs, and discontinuations due to AEs. The most common adverse reactions included headache (2.9%), nausea (1.9%), application site pain (1.5%), diarrhea (1.5%), and vomiting (1.5%).

INTEGUMENT-1 and INTEGUMENT-2 (The INterventional Trial EvaluatinG roflUMilast cream for the treatmENt of aTopic dermatitis) were two identical Phase 3, parallel group, double blind, vehicle-controlled trials evaluating the safety and efficacy of roflumilast cream 0.15% in AD.

About Atopic Dermatitis
AD is the most common type of eczema, affecting approximately 9.6 million children and 16.5 million adults in the United States. It is characterized by a defect in the skin barrier, which allows allergens and other irritants to enter the skin, leading to an immune reaction and inflammation. This reaction produces a red, itchy rash, most frequently occurring on the face, arms, and legs, and in some cases covers half of the body or more.

About Roflumilast Cream
Roflumilast cream is a next generation topical phosphodiesterase-4 (PDE4) inhibitor. PDE4 – an established target in dermatology – is an intracellular enzyme that increases the production of pro-inflammatory mediators and decreases production of anti-inflammatory mediators. Roflumilast cream 0.3% (ZORYVE^®) is approved by the Food and Drug Administration (FDA) for the topical treatment of plaque psoriasis, including intertriginous areas, in patients 6 years of age and older. Investigational roflumilast cream was evaluated at lower doses for atopic dermatitis: 0.15% for adults and children 6 years of age and older and 0.05% for children aged 2 to 5 years. Roflumilast cream 0.15% is under review at the FDA for the treatment of adults and children 6 years of age and older with a Prescription Drug User Fee Act (PDUFA) target action date of July 07, 2024.

Roflumilast cream is uniquely formulated as a non-greasy emollient cream that absorbs quickly and does not disrupt the skin barrier. In addition, roflumilast cream does not include sensitizing excipients or irritants, such as propylene glycol, polyethylene glycol, isopropyl alcohol, ethanol, or fragrances.

About ZORYVE^® Cream
ZORYVE (roflumilast) cream 0.3% is indicated for topical treatment of plaque psoriasis, including intertriginous areas, in patients 6 years of age and older.

IMPORTANT SAFETY INFORMATION
ZORYVE is contraindicated in patients with moderate to severe liver impairment (Child-Pugh B or C).

The most common adverse reactions (≥1%) include diarrhea (3.1%), headache (2.4%), insomnia (1.4%), nausea (1.2%), application site pain (1.0%), upper respiratory tract infection (1.0%), and urinary tract infection (1.0%).
