Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Subjects with moderate papulopustular rosacea will be treated either with azelaic acid 15% gel topically plus an anti-inflammatory dose of doxycyline (40mg) daily or with metronidazole 1% gel topically once daily plus an anti-inflammatory dose of doxycycline (40mg) over at total of twelve weeks to determine the rapidity of improvement, and the length of time to reach 25%, 50% and 75% clearing compared to baseline.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The change in inflammatory lesion count will be assessed at each post-baseline visit by an analysis of variance model (ANOVA) with factors treatment and center, but not including treatment-by-center interaction.

Investigator's Global Assessment (IGA) of papulopustular rosacea (static score): 0 - Clear (Virtually no rosacea ie, no papules and/or pustules; no or residual erythema; no or mild to moderate degree of telangiectasia may be present); 1 - Minimal (Rare papules and/or pustules; residual to mild erythema; mild to moderate degree of telangiectasia may be present); 2 - Mild (Few papules and/or pustules; mild erythema; mild to moderate degree of telangiectasia may be present); 3 - Mild to moderate (Distinct number of papules and/or pustules; mild to moderate erythema; mild to moderate degree of telangiectasia may be present); 4 - Moderate (Pronounced number of papules and/or pustules; moderate erythema; mild to moderate degree of telangiectasia may be present); 5 - Moderate to severe (Many papules and/or pustules, occasionally with large inflamed lesions; moderate erythema; moderate degree of telangiectasia may be present); 6 - Severe (Numerous papules and/or pustules, occasionally with confluent areas of inflamed lesions; moderate or severe erythema; moderate or severe degree of telangiectasia may be present).
