Effects of Tazarotene 0.045% Lotion on Quality of Life in Patients With Moderate-to-Severe Acne.

BACKGROUND In two phase 3 trials (NCT03168334, NCT03168321), participants with moderate-to-severe acne had significant symptom improvements after 12 weeks of treatment with tazarotene 0.045% lotion. Given the negative psychosocial effects of acne on patients, data from these studies were analyzed to evaluate quality of life in various subgroups. METHODS Mean changes from baseline to week 12 in Acne-Specific Quality of Life (Acne-QoL) domain and item scores were analyzed in the pooled intent-to-treat (ITT) population and in participants who were categorized as follows: Evaluator's Global Severity Score (EGSS) score=3 (“moderate”) or score=4 (“severe”) at baseline; Acne-QoL total score ≥60 (better quality of life) or <60 (worse quality of life), based on the median score at baseline. Exploratory analyses based on sex and race were also performed. RESULTS In the pooled ITT population (N=1614), Acne-QoL improvements were greater with tazarotene 0.045% lotion versus vehicle lotion, with significant differences in the acne symptoms domain, 3 acne symptom items, 2 self-perception items, 1 role-emotional item, and 1 role-social item (all P<0.05). Acne-QoL improvements with tazarotene 0.045% lotion were comparable between the EGSS subgroups. However, participants who self-reported worse quality of life at baseline (Acne-QoL total score <60) had notably greater improvements than those with better quality of life. Female and Black participants had greater Acne-QoL improvements than male and White participants. CONCLUSIONS Participants treated with tazarotene 0.045% lotion had significant quality-of-life improvements. Clinician-rated symptom severity appeared to have a smaller effect on Acne-QoL outcomes than participants’ own assessments of quality of life.
