The 0.3% foam, marketed as Zoryve, applied once-daily, is indicated for patients aged 9 years and older with seborrheic dermatitis, and can be used anywhere on the body, including areas with hair, with no limits on duration of use, according to the company, Arcutis. A 0.3% cream formulation of roflumilast was previously approved by the FDA for the topical treatment of plaque psoriasis in patients aged 6 years and older.
Approval was based on data from the phase 3 STRATUM trial and an accompanying phase 2 study known as Trial 203. These studies included a total of 683 adults and youth aged 9 years and older with seborrheic dermatitis. Participants were randomized to roflumilast or a placebo.
At 8 weeks, 79.5 % of patients on roflumilast met the primary efficacy endpoint of Investigator Global Assessment (IGA) scores of 0 or 1 (clear or almost clear) compared with 58.0% of patients on placebo (P < .001); the results were similar in the phase 2 Trial 203 (73.1% vs. 40.8%, respectively; P < .001). Overall, more than 50% of the patients on roflumilast achieved a clear score.
Patients in the roflumilast group also showed significant improvement in all secondary endpoints, including itching, scaling, and erythema, according to the company.
In the STRATUM study, 62.8% of roflumilast-treated patients and 40.6% of placebo patients achieved a 4-point or more reduction in itch based on the Worst Itch Numerical Rating Score (P =.0001), and 28% of roflumilast-treated patients reported significant itch improvement within the first 48 hours of use, compared with 13% of placebo patients (P = .0024).
Over a treatment period of up to 1 year, no treatment-related severe adverse events were reported in the phase 2 and 3 studies. The incidence of treatment emergent adverse events was similar between the treatment and placebo groups, and the most common adverse events (occurring in 1% of more of patients) across both studies were nasopharyngitis (1.5%), nausea (1.3%), and headache (1.1%).
Roflumilast foam is scheduled to be available by the end of January 2024, according to the company. The product is for topical use only, and contraindicated for individuals with severe liver impairment.
