PowerPoint Presentation PRESENTED AT 40TH ANNUAL FALL CLINICAL DERMATOLOGY CONFERENCE, OCTOBER 29–NOVEMBER 1, 2020 Roflumilast Cream (ARQ-151) Improved Itch Severity and Itch-Related Sleep Loss in Adults With Chronic Plaque Psoriasis in a Phase 2b Study INTRODUCTION • Roflumilast cream (ARQ-151), a potent phosphodiesterase-4 (PDE-4) inhibitor, is under investigation as a once-daily topical treatment for plaque psoriasis1,2 • In a randomized, double-blind, phase 2b trial of 331 adults with chronic plaque psoriasis, roflumilast cream administered once daily was superior to vehicle cream2 – Primary endpoint of achievement of “clear” or “almost clear” skin based on Investigator Global Assessment (IGA) at Week 6 was met • Roflumilast 0.3%: 28.0% (P<0.001 vs vehicle) • Roflumilast 0.15%: 22.8% (P=0.004 vs vehicle) • Vehicle: 8.3% – Treatment-related adverse events (AEs), including application site pain, were uncommon and the frequency was similar in all groups • Here we report the effect of roflumilast cream on itch, a highly prevalent and frequently bothersome symptom of chronic plaque psoriasis that negatively impacts quality of life,3 assessed using patient-reported outcome (PRO) measures in this study OBJECTIVE • To assess the effect of roflumilast cream on various PROs related to itch METHODS • Design: parallel-group, randomized, double-blind, vehicle-controlled phase 2b study (ClinicalTrials.gov NCT03638258; Figure 1)2 • Location: 30 sites in the United States and Canada CONCLUSIONS • Once-daily roflumilast cream demonstrated significant improvement in reducing itch in patients with psoriasis compared with vehicle cream – Patients reported a rapid and clinically significant reduction in the severity and burden of itch – Significant itch reduction occurred by Week 2 and continued with further reductions through Week 12 – In a subgroup of patients with greater severity of itch at baseline (WI-NRS ≥6), more than half of the patients had a substantial (≥4-point) reduction in itch by Week 6, and the response rate continued to increase through Week 12 – Reduction in itch resulted in significant improvement in sleep loss by Week 6 • Roflumilast cream was well-tolerated and application site pain was uncommon and similar to vehicle Table 1.

In a phase 2b study, roflumilast cream, an investigational once-daily, nonsteroidal topical PDE-4 inhibitor, was effective in achieving “clear” or “almost clear” skin and improving itch and itch-related sleep loss in patients with chronic plaque psoriasis REFERENCES 1.
