WESTLAKE VILLAGE, Calif. and MILAN, Italy, Sept. 09, 2022 (GLOBE NEWSWIRE) -- Arcutis Biotherapeutics, Inc. (Nasdaq: ARQT), an early-stage commercial company focused on developing meaningful innovations in immuno-dermatology, today announced new data from the STRATUM pivotal Phase 3 trial investigating roflumilast foam as a potential treatment for children ages 9 and above and adults with moderate to severe seborrheic dermatitis were presented orally at the Academy of Dermatology and Venereology (EADV) Congress. Roflumilast foam 0.3% is an investigational once-daily topical foam formulation of a highly potent and selective phosphodiesterase type 4 (PDE4) inhibitor being developed to treat inflammatory dermatoses, particularly in hair-bearing areas of the body such as the scalp.
The study met the primary endpoint with 80.1% of individuals treated with roflumilast foam achieving ‘IGA Success’ compared to 59.2% of patients treated with vehicle (P<0.0001) at week eight. IGA Success was defined as an IGA score of clear or almost clear plus a ≥2 grade improvement from baseline. Improvement with roflumilast foam was seen early, with roflumilast separating statistically from vehicle on IGA Success at week two, the first timepoint assessed.
“Topical therapies are the standard of care for the treatment of seborrheic dermatitis, but today’s options come with limitations, including side effects and the inability to use on both hair- and non-hair- bearing areas of the body,” said Dr. Andrew Blauvelt, M.D., M.B.A., lead study author and president of Oregon Medical Research Center. “Roflumilast foam demonstrated strong efficacy across multiple endpoints, including 50% of individuals with seborrheic dermatitis achieving IGA clear at week 8. Local tolerability was also highly favorable as reported by both patient and investigator assessments of irritation, burning, and stinging.”
Roflumilast foam also demonstrated statistically significant improvements compared to vehicle on all secondary endpoints in the trial, including itch, scaling, and erythema (redness).
Roflumilast foam was well-tolerated. The incidence of Treatment Emergent Adverse Events (TEAEs) was low and similar between active treatment and vehicle, with most TEAEs assessed as mild to moderate severity. There were no treatment-related Serious Adverse Events (SAEs). Overall, the most common adverse events in the study population (over 1%) included COVID-19, urinary tract infection, nasopharyngitis, and nausea. Over 90% of patients who were randomized to roflumilast foam in the study completed the full eight weeks, and there were few discontinuations due to adverse events (0.7% and 2.0% in the roflumilast foam and vehicle groups, respectively). Roflumilast foam demonstrated favorable local tolerability with no evidence of irritation in >98% of patients as assessed by the investigator and no or mild sensations in reported by >92% across all timepoints and treatment groups.
“We are excited to share these additional data from our STRATUM phase 3 trial which show the potential for roflumilast foam to treat multiple signs and symptoms of seborrheic dermatitis, including itch, redness, and scaling,” said Patrick Burnett MD, PhD, FAAD, Chief Medical Officer at Arcutis. “Roflumilast foam continues to demonstrate strong efficacy with a safety and tolerability profile that, if approved, should provide an important new non-steroidal treatment option for chronic use anywhere on the body, including the scalp.”
Arcutis plans to submit an NDA for roflumilast foam for the treatment of seborrheic dermatitis to the U.S. Food and Drug Administration (FDA) in the first quarter of 2023.
About STRATUM
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 foam 0.3% administered once-daily. A total of 457 subjects ages nine years and older with moderate to severe seborrheic dermatitis were enrolled in the study and were randomized 2:1 roflumilast foam to vehicle. The primary endpoint of the study was the proportion of subjects achieving IGA Success, defined as an IGA score of clear or almost clear plus a ≥2 grade improvement at week 8.
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 in areas of the body with oil-producing (sebaceous) glands, including the scalp, face (especially on the nose, eyebrows, ears, and eyelids), upper chest, and back.
About Topical Roflumilast
Arcutis is developing topical cream and foam formulations of roflumilast – a highly potent and selective PDE4 inhibitor being investigated as a once-daily, nonsteroidal, topical treatment for multiple dermatologic conditions. 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 12 years of age and older. Roflumilast foam is a once-daily topical foam formulation of roflumilast which the Company is developing for both seborrheic dermatitis and scalp and body psoriasis.
About ZORYVE
ZORYVE (roflumilast) cream 0.3% is indicated for topical treatment of plaque psoriasis, including intertriginous areas, in patients 12 years of age and older.
IMPORTANT SAFETY INFORMATION
The use of 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%), headache (2%), insomnia (1%), nausea (1%), application site pain (1%), upper respiratory tract infection (1%), and urinary tract infection (1%).
