Participating in dermatology research can be a fulfilling part of a dermatologist’s career. So how can a dermatologist start participating in clinical trials? Next Steps in Derm, in partnership with ODAC Dermatology, Aesthetic & Surgical Conference, interviewed Dr. Leon Kircik, clinical professor of dermatology at Icahn School of Medicine. Watch as Dr. Kircik shares the three pillars of a clinical research business. Find out why you should first look at your patient base before considering what you can study. Hear why Dr. Kircik says a clinical study coordinator is almost more important than your spouse. Plus find out the additional medical equipment needed for clinical research.

ABSTRACT
Background: A once-daily, three-pronged approach using an antibiotic, antibacterial, and retinoid may provide faster acne improvement versus monotherapy or dual-combination products. This post hoc analysis compared threshold acne lesion reductions with clindamycin phosphate 1.2%/adapalene 0.15%/benzoyl peroxide 3.1% (CAB) gel — the first FDA-approved triple-combination topical acne product — to its dyads and vehicle.
Methods: Phase 2 (N=741; NCT03170388) and phase 3 (N=183; N=180; NCT04214639; NCT04214652), double-blind, 12-week studies randomized participants aged ≥9 years with moderate-to-severe acne to once-daily CAB or vehicle gel; the phase 2 study included three additional dyad gel arms. The pooled percentage of participants achieving =>33%, =>50%, and =>75% reduction in inflammatory and noninflammatory acne lesions was evaluated.
Results: As early as week 4 in the phase 2 study, =>33% reduction in inflammatory lesions occurred in a significantly greater percentage of CAB gel-treated participants (82.7%) than with the 3 dyads and vehicle (61.1-69.8%; P<0.05, all). These early reductions were sustained throughout the study, with significantly (P<0.05) more CAB-treated participants achieving ≥50% reduction in inflammatory lesions versus dyads and vehicle from weeks 4-12. By week 12, CAB led to substantial reductions of =>75% in significantly more participants than dyads and vehicle (65.8% vs 49.9-51.2% and 21.6%; P<0.05, all). Similar trends were observed for noninflammatory lesions in the phase 2 study and for inflammatory and noninflammatory lesions in the phase 3 studies.
Conclusions: Lesion count reductions were significantly greater with CAB versus its dyads and vehicle gel as early as week 4, with substantial reductions observed after 12 weeks of treatment. This faster-acting and sustained efficacy of CAB gel — coupled with its optimized formulation, once-daily dosing, and tolerability — may positively impact treatment adherence.
ABSTRACT
Introduction: Moisturizers are often used as adjuvant therapy for psoriasis to assist with rehydration and skin barrier restoration. Fixed-combination halobetasol propionate 0.01% and tazarotene 0.045% lotion (HP/TAZ) is indicated for the topical treatment of plaque psoriasis in adults, with a demonstrated clinical profile in two phase 3 trials. However, the effect of application order with HP/TAZ has yet to be explored. This study evaluated the clinical profile of HP/TAZ applied before versus after a ceramide-containing moisturizer in adults with mild-to-moderate plaque psoriasis.
Methods: Sixteen participants were randomized to apply HP/TAZ followed by moisturizer on one side and moisturizer followed by HP/TAZ on the other side once daily for 12 weeks. Tolerability, safety, efficacy, and quality of life endpoints were assessed.
Results: Significant Investigator’s Global Assessment improvement was observed across all time points (P≤0.003) regardless of application order. Total Dermatology Life Quality Index scores significantly improved at all time points (P≤0.003), and visual analog scale for itch significantly improved at weeks 4, 8, and 12 (P<0.008). Four moderate adverse events were experienced by 3 participants. Two participants reported itching/irritation, which was worse when HP/TAZ was applied first.
Conclusions: The application order of moisturizer did not decrease therapeutic efficacy of HP/TAZ. Moisturizer application before HP/TAZ may reduce incidence of application site adverse events, ultimately increasing tolerability and supporting the real-world recommendation that applying a ceramide-containing moisturizer before HP/TAZ, versus after, results in a safe and effective therapeutic option for plaque psoriasis.
