Item 8.01. Other Events.
On November 15, 2022 and December 12, 2022, Arcutis Biotherapeutics, Inc. (the "Company") announced positive topline results from its “INterventional Trial EvaluatinG roflUMilast cream for the treatmENt of aTopic dermatitis” 1 (INTEGUMENT-1) trial and its “INterventional Trial EvaluatinG roflUMilast cream for the treatmENt of aTopic dermatitis” 2 (INTEGUMENT-2) trial, respectively. These twin pivotal phase 3 trials investigated roflumilast cream 0.15% as a potential treatment for adults and children ages six years and older with mild to moderate atopic dermatitis. Each trial was a phase 3, randomized, parallel group, double-blind, vehicle-controlled trial in which subjects ages six and older with mild to moderate atopic dermatitis involving 3% or greater body surface area received four weeks of (i) roflumilast cream 0.15% once daily or (ii) vehicle once daily. A total of 654 subjects were enrolled in INTEGUMENT-1 and a total of 683 subjects were enrolled in INTEGUMENT-2.
In each of INTEGUMENT-1 and INTEGUMENT-2, results from the four-week treatment period demonstrated statistically significant improvements compared to matching vehicle. The primary endpoint for each trial was the percentage of patients achieving Investigator Global Assessment (IGA) success, which was defined as a validated Investigator Global Assessment – Atopic Dermatitis (vIGA-AD) score of "clear" or "almost clear" plus a 2-grade improvement from baseline at week four. For INTEGUMENT-1, 32.0% of patients treated with roflumilast cream 0.15% achieved IGA success, compared to 15.2% of patients treated with vehicle (p < 0.0001). For INTEGUMENT-2, 28.9% of patients treated with roflumilast cream 0.15% achieved IGA success, compared to 12.0% of patients treated with vehicle (p < 0.0001).
In each of INTEGUMENT-1 and INTEGUMENT-2, roflumilast cream 0.15% also demonstrated statistically significant improvements compared to vehicle on key secondary endpoints, including 75% reduction in Eczema Area and Severity Index (EASI-75) and reductions in itch as measured by the Worst Itch-Numerical Rating Scale (WI-NRS). The following table sets forth a summary of the topline results from INTEGUMENT-1 and INTEGUMENT-2:
| | | | | | | | | | | | | | | | | | | | |
| INTEGUMENT-1 Week 4 | INTEGUMENT-2 Week 4 |
| Roflumilast cream | Vehicle | P-value | Roflumilast cream | Vehicle | P-value |
vIGA-AD | 32.0% | 15.2% | P<0.0001 | 28.9% | 12.0% | P<0.0001 |
EASI-75 | 43.2% | 22.0% | P<0.0001 | 42.0% | 19.7% | P<0.0001 |
WI-NRS | 33.6% | 20.7% | P<0.01 | 30.2% | 12.4% | P<0.01 |
In each of INTEGUMENT-1 and INTEGUMENT-2, roflumilast cream 0.15% was well-tolerated, with rates of treatment-emergent adverse events ("TEAEs") low across the active treatment and vehicle arms, with most TEAEs assessed as mild to moderate in severity. Overall, adverse events were uncommon, with no adverse event occurring in more than 3.5% of subjects in either arm of either trial. In INTEGUMENT-1, the most frequent adverse events (>1%) included headache, nausea, application site pain, nasopharyngitis, COVID-19, diarrhea, and vomiting. In INTEGUMENT-2, the most frequent adverse events (>1%) included headache, nausea, vomiting, diarrhea, upper respiratory tract infection, and COVID-19. Of the subjects treated with roflumilast cream 0.15% in INTEGUMENT-1 and INTEGUMENT-2, 404 (93% of subjects) and 410 (90% of subjects), respectively, completed the study. In each trial, there were few discontinuations due to adverse events in both the roflumilast cream 0.15% group and the vehicle group. In INTEGUMENT-1, six subjects treated with roflumilast cream 0.15% (1.4% of subjects treated with roflumilast cream 0.15%) and three subjects in the vehicle group (1.4% of subjects in the vehicle group) discontinuing the trial due to an adverse event. In INTEGUMENT-2, eight subjects treated with roflumilast cream 0.15% (1.8% of subjects treated with roflumilast cream 0.15%) and two subjects in the vehicle group (0.9% of subjects in the vehicle group) discontinuing the trial due to an adverse event. There were two treatment-related serious adverse events in INTEGUMENT-2 (0.4% of subjects treated with roflumilast cream 0.15%).
