A Study of S5G4T-1 in the Treatment of Papulopustular Rosacea

Study Overview
=================
Brief Summary
-----------------
To assess the efficacy and safety of S5G4T-1 compared to its vehicle when applied once daily for 12 weeks in participants with papulopustular rosacea.

Detailed Description
-----------------
In this Phase 3, double-blind, vehicle-controlled, parallel-group pivotal study, participants will be admitted only after a written informed consent has been obtained and after all inclusion/exclusion criteria have been met. Male and female participants at least 18 years of age with moderate or severe papulopustular rosacea will be eligible for enrollment for daily treatment with S5G4T-1 or its vehicle for 12 weeks.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: S5G4T-1<br>Participants will topically apply S5G4T-1 cream, once daily to face for 12 weeks. | Drug: S5G4T-1<br>* Once a day topical cream<br>* Other names: Encapsulated benzoyl peroxide (E-BPO) cream;|
| Placebo Comparator: S5G4T-2 Vehicle Cream<br>Participants will topically apply S5G4T-2 vehicle cream, once daily to face for 12 weeks. | Drug: S5G4T-2<br>* Once a day topical cream<br>* Other names: Vehicle cream;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Achieving an IGA Score of Clear or Almost Clear From Baseline at Week 12 | Percentage of participants in each treatment group achieving an acne severity IGA score of clear (score=0) or almost clear (score=1). | Baseline through Week 12 | 
| Change From Baseline in Inflammatory Lesion Counts at Week 12 | Inflammatory lesions were characterized as papules and pustules. A papule was defined as a solid, elevated inflammatory lesion equal to or less than 5 mm in diameter. A pustule was defined as an elevated inflammatory lesion equal to or less than 5 mm in diameter and contains pus (yellow-white exudate). Least squares means and standard deviations from an analysis of covariance (ANCOVA) with factors of treatment, analysis center and treatment by analysis center interaction and the Baseline lesion count as a covariate. Negative least squares means values represent decrease from Baseline. | Baseline, Week 12 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percent Change From Baseline in Inflammatory Lesion Counts at Week 12 | Inflammatory lesions were characterized as papules and pustules. A papule was defined as a solid, elevated inflammatory lesion equal to or less than 5 mm in diameter. A pustule was defined as an elevated inflammatory lesion equal to or less than 5 mm in diameter and contains pus (yellow-white exudate). Least squares means and standard deviations from an analysis of covariance (ANCOVA) with factors of treatment, analysis center and treatment by analysis center interaction and the Baseline lesion count as a covariate. Negative least squares means values represent decrease from Baseline. | Baseline, Week 12 |
