ACKNOWLEDGEMENTS: Medical writing support was provided by Prescott Medical Communications Group (Chicago, IL) with financial support from Ortho Dermatologics | Presented at the Fall Clinical Dermatology Conference • October 17-20, 2019 • Las Vegas, NV SYNOPSIS ◾ Psoriasis is a chronic, immune-mediated disease that varies widely in its clinical expression1 ◾ Topical corticosteroids are the mainstay of treatment in psoriasis, but long-term safety remains a concern, limiting use, and posttreatment flare-up is common2 ◾ While psoriasis commonly affects lower extremities, treatment can be more problematic, and burden of disease heightened3,4 ◾ Recent phase 3 clinical data have demonstrated that halobetasol propionate (HP) 0.01% lotion (ByhaliTM Ortho Dermatologics, Bridgewater, NJ) was significantly more effective than vehicle after 8 weeks of treatment in patients with moderate-to-severe localized plaque psoriasis,5,6 though efficacy in specific locations has not been reported OBJECTIVE ◾ To investigate the efficacy of once-daily HP 0.01% lotion versus vehicle in patients with moderate- to-severe plaque psoriasis of the lower extremities METHODS Study Design ◾ Data from two phase 3, multicenter, randomized, double-blind studies of patients with moderate- to-severe psoriasis were pooled5,6 ◾ Participants were randomized (2:1) to receive HP 0.01% lotion or vehicle once-daily for 8 weeks, with a 4-week posttreatment follow-up ◾ At baseline, participants were required to have Investigator Global Assessment (IGA) score of 3 or 4 (5-point scale; 0=clear and 4=severe) and Body Surface Area (BSA) of 3% to 12% ◾ A post hoc analysis was conducted in a subset of patients with plaque psoriasis of the lower extremities, with a target lesion on the leg • For the target lesion, participants needed a score of ≥3 for at least 2 of 3 signs of psoriasis (erythema, plaque elevation, and scaling [5 point scale; 0=clear and 4=severe]), a sum of at least 8, and could not have a score of 0 or 1 in any one of the signs • Target could not be on areas covering bony prominences (ie, knees); however, overall psoriasis assessment (IGA and BSA) did not exclude the knees ◾ In these studies, CeraVe® hydrating cleanser and CeraVe® moisturizing lotion (L’Oreal, NY) were provided as needed for optimal moisturization/cleaning of the skin Efficacy Assessments ◾ Treatment success (≥2-grade improvement from baseline) in each individual sign of psoriasis (erythema, plaque elevation, and scaling) at the target lesion (leg) ◾ Overall treatment success (≥2-grade improvement from baseline in IGA score and a score of ‘clear’ or ‘almost clear’ [0 or 1]) ◾ Improvements in overall mean BSA from baseline Halobetasol 0.01% Lotion in the Treatment of Moderate-to-Severe Plaque Psoriasis of the Lower Extremities Neal D Bhatia, MD1; Tracey C Vlahovic, DPM2; Lawrence Green, MD3; Gina Martin, MOT4; Tina Lin, PharmD5 1Therapeutics Clinical Research, San Diego, CA; 2Temple University School of Podiatric Medicine, Philadelphia, PA; 3Department of Dermatology, George Washington University School of Medicine, Washington, DC; 4Bausch Health Americas, Inc., Petaluma, CA; 5Ortho Dermatologics, Bridgewater, NJ ◾ Reductions of ≥50% and ≥75% of overall IGAxBSA from baseline (IGAxBSA-50 and IGAxBSA-75) at Week 8 ◾ Quality of life (QoL) with 10 question Dermatology Life Quality Index (DLQI; 4-point scale; 0=not at all/not relevant and 3=very much) • Mean change in DLQI of 4 was considered a minimal clinically important difference (MCID)7 RESULTS ◾ This analysis included 234 patients where leg was identified as the target lesion (HP 0.01% lotion, n=151; vehicle, n=83) ◾ At the end of the 8-week treatment period, more than half of participants receiving HP 0.01% lotion achieved treatment success at the target lesion, with 52.1%, 55.5%, and 58.2% achieving ≥2-grade reduction in erythema, plaque elevation, and scaling severity on the leg, compared with 15.7%, 22.9% and 22.2% of those treated with vehicle, respectively (P<0.001 all; Figure 1) FIGURE 1: Treatment Successa in Psoriasis Signs of (A) Erythema, (B) Plaque Elevation, and (C) Scaling 0% 30% 20% 10% 40% 50% 60% 70% Study Visit (Weeks) P e rc e n ta g e o f P a rt ic ip a n ts 0 2 4 6 8 A.
