Abstract
Acne is the most common skin condition affecting up to 25 million Americans annually and has been shown to negatively impact patient’s quality of life (QoL).[1] The Acne Quality of Life Questionnaire (Acne-QoL) was included as an exploratory endpoint in two multicenter, randomized, double-blind, vehicle-controlled Phase III studies of patients (≥9 years) with moderate-to-severe acne receiving IDP- 126 Gel or vehicle. A post hoc exploratory analysis was conducted using pooled data (N=309) from both Phase III studies to assess whether changes from baseline to week 12 in Acne-QoL domain scores (self- perception; role-emotional; role-social; acne symptoms) significantly differ between IDP-126 Gel and vehicle and whether these differences were clinically meaningful to patients, based on responder thresholds defined by McLeod et al.[2]. Acne-QoL domain scores significantly (all p < 0.001) improved for patients treated with IDP-126 Gel vs. vehicle in all four domains: role-emotional (mean difference: 4.1), self-perception (mean difference: 3.8), acne symptoms (mean difference: 2.6) and role-social (mean difference: 2.0). The proportion of responders was significantly higher (all p < 0.05) in the IDP-126 Gel group vs. vehicle for all Acne-QoL domains—self-perception (Odds Ratio [OR]:4.32, 95% Confidence Interval [CI]: 2.16-8.65), acne symptoms (OR:3.90, 95% CI: 2.11-7.23), role-social (OR:3.59, 95% CI: 1.73- 7.47) and role-emotional (OR:2.50, 95% CI: 1.36-4.58). Overall, in this post hoc exploratory analysis of pooled data from two Phase III studies, participants with moderate-to-severe acne reported statistically significant and clinically meaningful improvements in all four Acne-QoL domains after 12 weeks of treatment with IDP-126 Gel.
