Participant Reported Outcomes With Use of Trifarotene 50 μg/g Cream in the Treatment of Moderate Facial and Truncal Acne Vulgaris

The DLQI was validated 10-item questionnaire for participants aged >16 years that measured the dermatology-related limitations of functional ability and the frequency, severity, and impact of general inflammatory skin conditions on the quality-of-life (QOL). The total DLQI score was calculated by summing the scores of each question, resulting in a maximum of 30 and a minimum of 0. Responses to each questions were assessed on a scale of 0 to 3, where 0 is "not at all" and 3 is "very much". Scores from all 10 questions added up to give total DLQI scores ranged from 0 (not at all) to 30 (very much), higher scores indicated more impact on quality of life.

The C-DLQI are validated 10-item questionnaire for participants aged <=16 that measured the dermatology related limitations of functional ability and the frequency, severity, and impact of general inflammatory skin conditions on the quality-of-life (QOL). Questions were scored as follows: No effect (0-1), Small effect (2-6), Moderate effect (7-12), Very large effect (13-18), Extremely large effect (19-30). The total C-DLQI score was calculated by summing the scores of each question, resulting in a maximum of 30 (Extremely large effect) and a minimum of 0 (No effect). A lower score on the C-DLQI indicates increased QOL.

The CompAQ questionnaire is a comprehensive measure of facial and truncal acne's impact on health-related QOL. The 20 questions consisted of 5 domains that assessed a variety of psychosocial and physical impacts of acne: Psychological/Emotional, Social (Judgement from Others), Social Interactions, Treatment Concerns, Physical Symptoms. Each question is assessed with a numeric score between 0 (Never) and 8 (All the time) with a total possible score range of 0 (No effect) -160 (greater adverse impact). The higher the score, the more quality of life is impaired.

Participants Satisfaction Questionnaire included questions: a) How bothered were you by treatment side effects? : Not bothered at all, Bothered somewhat, Bothered, Bothered a great deal b) Satisfied with the time it took for treatment to work: Very satisfied, Satisfied, Somewhat satisfied, Not satisfied c) How satisfied were you with the effectiveness of the treatment?

EQ-5D-5L is a 2-part measurement. The first part is comprised of the following 5 participant-reported dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The responses are used to derive the health state index scores using the United States (US) algorithm, with scores ranging from -0.109 (extreme problems) to 1 (no problems). A higher score indicates better health state.

The EQ-5D-5L assesses general health-related quality of life. The second portion of the scale is a self-perceived health score assessed using a VAS that ranges from 0 (the worst imaginable health) to 100 (the best imaginable health), with higher scores indicating higher health utility.

IGA was an assessment scale used to evaluate facial acne severity. IGA was recorded from components collected on the case report form (CRF) using a 5-point scale where (0 = clear; 1 = almost clear; 2 = mild; 3 = moderate; 4 = severe) based on inflammation, pustules and papulation/infiltration. Success Rate was defined as the percentage of participants who achieved an IGA score of 1 (Almost Clear) or 0 (Clear) and at least a 2-grade improvement from Baseline to Week 12 and Week 24.

The Physician's Global Assessment (PGA) was an instrument to evaluate the truncal acne severity in the shoulders, upper back and upper anterior chest areas. PGA was recorded from components collected on the CRF using a 5-point scale where (0 = clear; 1 = almost clear; 2 = mild; 3 = moderate; 4 = severe) based on inflammation, pustules and papulation/infiltration. Success Rate was defined as the percentage of participants who achieved an PGA score of 1 (Almost Clear) or 0 (Clear) and at least a 2-grade improvement from Baseline to Week 12 and Week 24. All missing values were imputed by LOCF.

Percent change from Baseline was calculated as the values at Week 12 (and 24) minus the value at Baseline divided by Baseline value * 100. All missing values were imputed by LOCF.
