• Approximately 40% of the 9 million individuals in the United States with plaque psoriasis experience involvement of the scalp
• Once-daily ZORYVE foam significantly improved both scalp and body psoriasis in a Phase 2b and a pivotal Phase 3 trial
• Data also show rapid reduction in scalp itch as soon as 24 hours after first application
• ZORYVE foam demonstrated a favorable safety and tolerability profile

WESTLAKE VILLAGE, Calif., July 23, 2024 (GLOBE NEWSWIRE) — Arcutis Biotherapeutics, Inc. (Nasdaq: ARQT), a commercial-stage biopharmaceutical company focused on developing meaningful innovations in immuno-dermatology, today announced the submission of a supplemental New Drug Application (sNDA) for ZORYVE (roflumilast) foam 0.3%, a once-daily, next generation phosphodiesterase-4 (PDE4) inhibitor, for the treatment of adults and adolescents ages 12 and over with scalp and body psoriasis.

“Nearly half of all individuals with plaque psoriasis have involvement of the scalp. Hair-bearing areas present unique treatment challenges that are not easily addressed with creams or ointments. Individuals with plaque psoriasis need steroid-free treatment options that clear plaques anywhere on the body and relieve burdensome symptoms, such as itch and flaking,” said Melinda Gooderham, MSc, MD, FRCPC, medical director, SKiN Centre for Dermatology, investigator with Probity Medical Research, and clinical trial investigator. “Clinical data show that investigational once-daily ZORYVE foam effectively and reliably cleared both scalp and body psoriasis across all efficacy endpoints compared to vehicle, including 67% of participants achieving Scalp-Investigator Global Assessment Success with ZORYVE foam at 8 weeks. These data demonstrate that ZORYVE foam, if approved, would be an important new treatment option for those living with psoriasis.”

“This important milestone represents our fifth topical roflumilast regulatory submission in the United States in less than three years and brings another innovative treatment to the large population of individuals with scalp and body psoriasis. Based on the rapid adoption of ZORYVE foam in seborrheic dermatitis due to the simplicity of using one treatment anywhere on the body, including hair-bearing areas, we believe there is great potential for its adoption in scalp and body psoriasis, once approved,” said Frank Watanabe, president and chief executive officer of Arcutis. “Our team’s ability to execute our clinical development and commercial strategies reinforces Arcutis’ leadership in medical dermatology and positions the ZORYVE portfolio as a new standard of care for the effective treatment of multiple immune-mediated, chronic skin diseases. I would like to thank the clinical investigators, study coordinators, patients, and caregivers who participated in our clinical trials.”

About the Data
The submission is supported by positive results from Arcutis’ pivotal ARRECTOR Phase 3 trial, a Phase 2b study, and long-term efficacy and safety data generated from the ZORYVE cream development program in plaque psoriasis.

The “A Randomized tRial Employing topiCal roflumilasT foam to treat scalp psORiasis” (ARRECTOR) study was a parallel group, double-blind, vehicle-controlled pivotal Phase 3 study of the safety and efficacy of roflumilast foam 0.3% or a matching vehicle administered once-daily in individuals with plaque psoriasis of the scalp and body ages 12 and older (n=432). The study met its co-primary endpoints with 67.3% of individuals treated with roflumilast foam achieving Scalp-Investigator Global Assessment (S-IGA) Success (IGA Success is defined as an IGA score of ‘clear’ or ‘almost clear’ plus a 2-point improvement from baseline) compared to 28.1% of individuals treated with a matching vehicle foam at Week 8 (P<0.0001), and 46.5% of individuals treated with roflumilast foam achieved Body-Investigator Global Assessment (B-IGA) Success compared to 20.8% of individuals treated with a matching vehicle foam at Week 8 (P<0.0001).

Two thirds (65.3%) of roflumilast-treated patients with clinically meaningful itch at baseline achieved a clinically significant reduction in itch compared to 30.3% of vehicle-treated patients at Week 8 (P<0.0001) as measured by a ≥ 4-point change from baseline in Scalp Itch-Numeric Rating Scale (SI-NRS). Importantly, some patients experienced rapid relief in scalp itch 24 hours following first application compared to vehicle (as measured by mean SI-NRS change from baseline P=0.0164).

In addition, improvement in body itch as measured by the Worst Itch-Numeric Rating Scale (WI-NRS) was also observed at Week 8, with 63.1% of those treated with roflumilast foam achieving a ≥ 4-point reduction in WI-NRS compared to 30.1% of those treated with vehicle (P<0.0001), as well as Week 2 (the earliest timepoint measured).

Roflumilast foam 0.3% was well tolerated. The incidence of Treatment Emergent Adverse Events (TEAEs) was low and generally similar between active treatment and vehicle, with most TEAEs assessed as mild to moderate severity. Overall, the most common adverse reactions for roflumilast foam in the phase 3 and phase 2b studies (≥1%) included headache (3.1%), diarrhea (2.5%), nausea (1.7%), and nasopharyngitis (1.3%). Rates of discontinuation due to adverse events were low and similar among roflumilast-treated (1.8%) and vehicle-treated (1.3%) patients.

About Scalp and Body Psoriasis
Scalp psoriasis is a manifestation of plaque psoriasis and sometimes extends to the forehead, back of the neck, or behind or inside the ears. Plaque psoriasis is characterized by raised, red areas of skin (“plaques”) covered with a silver or white scale. Individuals with scalp psoriasis commonly have plaques on other areas of the body as well. Approximately 40% of the estimated 9 million Americans with plaque psoriasis have involvement of the scalp. Scalp psoriasis plaques are identical to psoriatic plaques on other areas of the body; however, topical treatment of scalp plaques is complicated by the difficulty of delivering drugs onto the affected skin in hair bearing areas where traditional cream and ointment formulations can be difficult to apply. As with psoriatic plaques on other parts of the body, psoriasis on the scalp is often itchy and is sometimes painful. Scalp psoriasis can also be associated with hair loss, likely due to damage to the hair from excessive scratching, rubbing, or combing of the affected area. Often, individuals require two or more medications to manage their disease when they have scalp involvement.

About ZORYVE (roflumilast) Foam
Roflumilast foam is a once-daily topical foam formulation of roflumilast, 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 foam is uniquely formulated for use anywhere on the body, including hair-bearing areas. ZORYVE is the first and only branded topical therapy for three major inflammatory dermatoses.
