Safety and Efficacy Study of Clindamycin Phosphate 1.2% and Tretinoin 0.025% Gel to Treat Rosacea

Currently, there is no known cure for rosacea. The most effective treatment is systemic antibiotics, particularly of the tetracycline family. Topical treatments include metronidazole, antibacterials such as erythromycin and clindamycin, sulfacetamide and benzoyl peroxide. Isotretinoin (Accutane) is also used.

Inclusion criteria

• Able to complete study and comply with study procedures.

Exclusion criteria

• Acne conglobata, acne fulminans, secondary acne (chloracne, drug-induced acne, etc.), or severe acne requiring systemic treatment.

• Other dermatologic conditions that require the use of interfering topical or systemic therapy or that might interfere with study assessments such as, but not limited to, atopic dermatitis, perioral dermatitis or acne vulgaris.
• Clinically significant abnormal findings or conditions (other than rosacea), which might, in the opinion of the Investigator, interfere with study evaluations or pose a risk to subject safety during the study.
• Subjects who are pregnant or planning a pregnancy.
• Use of any investigational therapy within the past 4 weeks.
• Known hypersensitivity or previous allergic reaction to clindamycin or retinoids
