Arcutis Announces First Patient Enrolled in Phase 3 Clinical Trial of Topical Roflumilast Foam (ARQ-154) as a Potential Treatment for Seborrheic Dermatitis

  • Topical roflumilast potential “Best-in-Class” topical PDE4 inhibitor
  • Seborrheic dermatitis affects 10 million patients in the U.S.
  • Potential first new topical treatment for seborrheic dermatitis in decades
  • The Company anticipates topline data in the second or third quarter of 2022

WESTLAKE VILLAGE, Calif., July 12, 2021 (GLOBE NEWSWIRE) — Arcutis Biotherapeutics, Inc. (Nasdaq: ARQT), a late-stage biopharmaceutical company focused on developing meaningful innovations to address the urgent needs of patients living with immune-mediated dermatological diseases and conditions, or immuno-dermatology, today announced enrollment of the first patient in its single pivotal Phase 3 clinical trial evaluating topical roflumilast foam (ARQ-154) as a potential treatment for seborrheic dermatitis. Roflumilast foam is a once-daily topical foam formulation of roflumilast, a highly potent and selective phosphodiesterase type 4 (PDE4) inhibitor, which the Company is developing for seborrheic dermatitis and scalp psoriasis.

“The symptoms of seborrheic dermatitis can have a significant, negative influence on quality of life and can cause psychological distress for millions of affected Americans. Despite that, no novel treatments have been developed for this chronic skin condition in decades, and current topical treatments frequently provide inadequate efficacy or pose safety concerns that limit their use,” said Patrick Burnett, M.D., Ph.D., FAAD, Chief Medical Officer of Arcutis. “In our Phase 2 trial, roflumilast foam was demonstrated to be an effective, safe, and well-tolerated treatment for seborrheic dermatitis. We are now pleased to initiate this single Phase 3 pivotal trial, as we believe roflumilast foam, if approved, has the potential to become a much-needed new standard of care for people with seborrheic dermatitis. Unlike most treatments, roflumilast foam is suitable for all body areas, including hair-bearing areas and the face, and does not pose the safety concerns typically seen with topical steroids.”

The STudy of Roflumilast foam Applied Topically for the redUction of seborrheic derMatitis (STRATUM) is a Phase 3, parallel group, double blind, vehicle-controlled study of the safety and efficacy of roflumilast 0.3% foam administered once-daily in approximately 450 subjects ages nine and older with moderate to severe seborrheic dermatitis. The primary endpoint of the study is the proportion of subjects achieving Investigator Global Assessment (IGA) success, defined as an IGA score of “clear” or “almost clear” plus a 2-point improvement at eight weeks. The Company announced in January 2021 that it had conducted a successful End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) and planned to initiate a single pivotal Phase 3 trial in seborrheic dermatitis.

About Seborrheic Dermatitis
Seborrheic dermatitis affects more than 10 million people in the U.S., and is a common, chronic, or recurrent inflammatory skin disease that causes red patches covered with large, greasy, flaking yellow-gray scales, and persistent itch. Seborrheic dermatitis occurs most often on the scalp, face (especially on the nose, eyebrows, ears, and eyelids), upper chest, and back.

About Topical Roflumilast Foam
Roflumilast foam is a once-daily, topical formulation of a highly potent and selective PDE4 inhibitor (roflumilast). The foam formulation was designed to treat hair-bearing areas of the body, such as the scalp, although it is usable in all areas of the body, including the face. Roflumilast has been approved by the U.S. Food and Drug Administration (FDA) for oral treatment to reduce the risk of exacerbations of chronic obstructive pulmonary disease (COPD) since 2011. Roflumilast has shown greater potency (25- to 300-fold) than the two other FDA-approved PDE4 inhibitors for dermatology. PDE4 is an intracellular enzyme that increases the production of pro-inflammatory mediators and decreases production of anti-inflammatory mediators; it has been implicated in a wide range of inflammatory diseases including psoriasis, atopic dermatitis, and COPD. PDE4 is an established target in dermatology, and other PDE4 inhibitors have been approved by the FDA for the topical treatment of atopic dermatitis and the systemic treatment of plaque psoriasis.
