Rosacea
Conditions
Brief summary
Clinical assessments of efficacy will be conducted based on Investigator's Global Assessment (IGA, modified scale without erythema), Clinician's Erythema Assessment (CEA), and on inflammatory lesion counts at Weeks 4, 8, 12 and 16 in comparison to Baseline.
Detailed description
Two hundred (200) male and female subjects with papulopustular rosacea will be enrolled to get 176 completed subjects (forty-four (44) completers each in groups 1 to 4). After assessing eligibility during an up to 28 days screening period, 200 subjects will be enrolled in the study (fifty subjects each in groups 1 to 4). Subject visits are scheduled at Screening, Baseline (Day 1), and Weeks 4, 8, 12 and 16. Clinical assessments of efficacy will be conducted based on Investigator's Global Assessment (IGA, modified scale without erythema), Clinician's Erythema Assessment (CEA), and on inflammatory lesion counts at Weeks 4, 8, 12 and 16 in comparison to Baseline. Additionally, high sensitivity C-reactive protein (hs-CRP) in the blood will be assessed at Baseline, and at Week 16 to explore any impact of the treatment on the inflammatory pathology.

Eligibility
Inclusion criteria

| Investigator Global Assessment (IGA) 0=Clear, 1=Near Clear, 2=Mild, 3=Moderate, 4=Severe | 16 weeks | Proportion of subjects with Investigator Global Assessment (IGA) 'treatment success' - Grade 0 or 1 at the end of study with at least 2 grade reduction from Baseline to Week 16. |
| Total Inflammatory Lesion Count Reduction | 16 Weeks | The total inflammatory lesion count is carried out by visual inspection by the Investigator at every study visit from Screening up to Week 16 (or at early termination). Inflammatory lesions will be recorded on a diagram of a human face, divided in 4 quadrants. |

| Median Change in RosaQoL (Rosacea Quality of Life) Score From Baseline to Week 16 | Median change in the score from Baseline to Week 16 | The RosaQoL assessment is carried out by the Investigator using the validated RosaQoL questionnaire, at every study visit from Screening up to Week 16 (or at early termination). The RosaQol tool has 21 questions related to the impact that Rosacea has on various dimensions influencing quality of life. Each question is graded from 1 (Never) - 5 (All the time), thus leading to a minimum score of 21 (21 x 1) to a maximum score of 105 (21 x 5) per subject at every visit. Higher the score, poorer is the quality of life. This outcome measured the change in the score from Baseline to Week 16. |
