Primary Outcome

  • Percentage of participants with Investigator’s Global Assessment (IGA) based therapeutic success at end of treatment (LOCF: last observation carried forward)
    Static evaluation of overall severity of papulopustular rosacea at a given time: 1) Clear: no papules and/or pustules; no erythema; 2) Minimal: rare papules and/or pustules; faint up to but not including mild erythema; 3) Mild: few papules and/or pustules; mild erythema; 4) Moderate: pronounced number of papules and/or pustules (but less than numerous papules and/or pustules); moderate erythema; 5) Severe: numerous papules and/or pustules, occasionally with confluent areas of inflamed lesions; moderate to severe erythema.

  • Grouped changes from baseline in erythema intensity score at end of treatment (LOCF)
    Erythema was rated as: clear or almost clear; mild; moderate; or severe. For the assessment of the grouped change in erythema ratings, the baseline examination was used to group into ‘improved’, ‘no change’, or ‘worsened’. A participant was considered to have an ‘improved’ erythema rating if the erythema rating was lower compared to the baseline rating, ‘no change’ if the rating was identical, and ‘worsened’ if the rating was higher. The percentage of participants in each of these categories is presented.

  • Change from baseline in Rosacea quality of life (RosaQoL) questionnaire at end of treatment - Overall quality of life score
    The Rosacea Quality of Life (RosaQoL) is a questionnaire to evaluate the effect of rosacea on a participant’s quality of life. Each of the 21 items in this questionnaire asks about the frequency with which a particular aspect of living with rosacea affects the participant: possible responses for each item are “never” (score=1), “rarely” (score=2), “sometimes” (score=3), “often” (score=4), or “all the time” (score=5). The overall score is the sum of the results from all 21 questions, with possible scores ranging from 21 (best) to 105 (worst); the higher the score, the more quality of life is impaired. The mean (standard deviation) of the change, defined as end of treatment overall score minus baseline overall score, is presented.

  • Number of participants with change from baseline in Dermatology Life Quality Index (DLQI) questionnaire at end of treatment - Overall score
    The Dermatology Life Quality Index (DLQI) is a questionnaire consisting of a set of 10 questions that evaluate the degree to which the participant’s skin has affected certain behaviors and quality of life over the past week. Possible responses to each question are: “very much” (question 7: “yes”) (score=3), “a lot” (score=2), “a little” (score=1), or “not at all”/”not relevant” (score=0). The DLQI overall score is the sum of the results from all 10 questions, with possible scores ranging from 0 (best) to 30 (worst); the higher the score, the more quality of life is impaired. The number of participants with score changes (end of treatment – baseline) in DLQI overall score from baseline to end of treatment <=-5 and >-5 are presented.

  • Change from baseline in EuroQol Group Questionnaire-Visual analogue scale (EQ-VAS) at end of treatment
    The EuroQol Group Questionnaire-Visual Analogue Scale (EQ-VAS) is a standardized instrument for use as a measure of health outcome. The EQ-VAS asks for a judgment of the overall health status assessed by the participant her/himself. The 20-cm visual analog scale (VAS) has endpoints labeled "best imaginable health state" and "worst imaginable health state" that are anchored at 100 and 0, respectively. Respondents are asked to indicate how they rate their own health by drawing a line from an anchor box to that point on the EQ-VAS, which best represents their own health on that day; higher scores indicate a better health state. The median (range) of the change, defined as EQ-VAS at end of treatment minus EQ-VAS at baseline, is presented.

  • Change from baseline in index value at end of treatment
    The EuroQol Group Questionnaire–5 Dimensions–5 Levels (EQ-5D-5L) is a standardized instrument for use as a measure of health outcome. Applicable to a wide range of health conditions and treatments, it provides a simple descriptive profile and a single index value for health status. It is used to assess the level of current health for 5 domains: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression. Each dimension is evaluated using 5 levels: “no problems” (level 1), “slight problems” (level 2), “moderate problems” (level 3), “severe problems” (level 4), and “extreme problems” (level 5). A scoring formula developed by EuroQol Group calculates a single index value from the results from all 5 domains along a continuum of 0 (death) to 1 (full health). The median (range) change, defined as the index value at end of treatment minus the index value at baseline, is presented.
