WESTLAKE VILLAGE, Calif., Aug. 28, 2024 (GLOBE NEWSWIRE) -- Arcutis Biotherapeutics, Inc. (NASDAQ: ARQT), a commercial-stage biopharmaceutical company focused on developing meaningful innovations in immuno-dermatology, today announced results from the INTEGUMENT-OLE long-term open-label study of once-daily roflumilast cream 0.05% demonstrating the durable efficacy and favorable safety profile of roflumilast cream 0.05% in the treatment of mild to moderate AD in children 2 to 5 years old. In the study, roflumilast cream was well-tolerated, with no new safety signals observed during treatment of up to 56 weeks in duration. Efficacy was not only maintained but improved over time, with 71.9% of participants who rolled over from the roflumilast cream 0.05% treatment arm in INTEGUMENT-PED achieving 75% improvement from baseline in Eczema Area and Severity Index (EASI-75) after 56 weeks.

“When choosing a therapy for very young children, health care providers and caregivers are looking for treatments that provide both rapid relief and are well-tolerated and suitable for long-term use,” said Adelaide Hebert, MD, professor of dermatology and pediatrics at UTHealth Houston, and INTEGUMENT trial investigator. “These results build upon the findings from the Phase 3 trial of roflumilast cream 0.05% that demonstrated rapid efficacy within the first 4 weeks of treatment, and further showed long-term durable efficacy and tolerability of investigational roflumilast cream, with continued improvement over the course of the long-term study.”

In the study, 53.8% of participants who rolled over from the roflumilast cream treatment arm in INTEGUMENT-PED achieved a validated Investigator Global Assessment-Atopic Dermatitis (vIGA-AD) success, defined as vIGA-AD value of 0 or 1 plus a 2-grade improvement from baseline, at 56 weeks.

The long-term study results reinforce the safety and tolerability profile of roflumilast cream 0.05% already seen in the 4-week pivotal INTEGUMENT-PED clinical trial, with no new safety signals observed up to 56 weeks. Overall incidence of adverse events was low, with most being mild to moderate in nature. The most frequently reported adverse events (≥3%) included: upper respiratory tract infection, nasopharyngitis, pyrexia, influenza, COVID-19, and otitis media. Overall, only 3.0% of trial participants discontinued the study due to adverse events.

“Roflumilast cream is uniquely formulated with the AD patient in mind, to deliver treatment without sensitizing excipients and irritants, which can often disrupt the skin barrier. We are excited by these results, which reinforce the strength of our ZORYVE product portfolio and specifically demonstrate the long-term efficacy, safety and tolerability profile of our once-daily roflumilast cream for the treatment of pediatric AD,” said Patrick Burnett, MD, PhD, FAAD, chief medical officer at Arcutis. “Based on these positive results, we are convinced that, if approved, roflumilast cream 0.05% can help provide immediate as well as long-term management of this burdensome skin condition, expanding the treatment population to children down to age 2.”

Arcutis intends to submit an sNDA to the FDA in the first quarter of 2025 for roflumilast cream 0.05% for the treatment of AD in individuals ages 2-5 years. ZORYVE^® (roflumilast) cream 0.15% is approved for the topical treatment of mild to moderate AD in adults and pediatric patients down to age 6.

About INTEGUMENT-OLE

The “INterventional Trial EvaluatinG roflUMilast cream for the treatmENt of aTopic dermatitis Open Label Extension (INTEGUMENT-OLE) was a Phase 3, multicenter, open-label extension study of the long-term safety of roflumilast cream 0.15% in adults and children ages 6 years and older with AD and roflumilast cream 0.05% in children ages 2 to 5 years. A total of 562 individuals enrolled in the study after completing the INTEGUMENT-PED Phase 3 trial.

The study evaluated monotherapy with roflumilast cream 0.05% with no rescue treatment permitted. Beginning at Week 4 of INTEGUMENT-OLE, any participant who achieved vIGA-AD of ‘0-Clear’ switched to twice weekly maintenance treatment. Participants were able to continue twice weekly maintenance dosing, as long as vIGA-AD remained either ‘0‑Clear’ or ‘1-Almost Clear’. Participants resumed once-daily dosing if vIGA-AD reached ≥2-Mild, and could also resume once-daily dosing if signs/symptoms of AD were not adequately controlled with maintenance therapy.

The primary objective of the study was to assess the long-term safety of roflumilast cream. Secondary endpoints included vIGA-AD score of 0 or 1 at each assessment, vIGA-AD success defined as vIGA-AD value of 0 or 1 plus a 2-grade improvement from baseline, and Eczema Area and Severity Index (EASI) score over time. The assessment of vIGA-AD Success and EASI-75 response, as reported here, references baseline of INTEGUMENT-PED.

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. AD 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. The rash can cover significant areas of the body, in some cases half of the body or more. AD typically begins in early childhood and is chronic. It persists into adolescence and even adulthood in some individuals. The rash causes significant pruritus (itching), which can lead to skin damage caused by scratching or rubbing. Since a large percentage of AD patients are very young children, safety is a particularly important consideration in treatment selection.

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 FDA for the topical treatment of plaque psoriasis, including intertriginous areas, in patients 6 years of age and older. Roflumilast cream 0.15% (ZORYVE^®) is approved by the U.S. Food and Drug Administration (FDA) for the topical treatment of mild to moderate atopic dermatitis, in patients 6 years of age and older. A lower dose, roflumilast cream 0.05%, was evaluated for children aged 2 to 5 years.
