A Study Comparing Combination Clindamycin Phosphate/Tretinoin Gel Alone Versus With Benzoyl Peroxide Foaming Cloths for Facial Acne

Study Overview
=================
Brief Summary
-----------------
There are many different factors that cause acne. So combination treatment using different medications that can address these different factors is commonly used to treat acne. Fixed-dose combination clindamycin phosphate 1.2% and tretinoin 0.025% gel and benzoyl peroxide 6% foaming cloths are both used to treat acne. This study will evaluate the use of the medications when used together.

Subjects or their guardians must be able to read, sign, and date the informed consent, and abide by study restrictions for its duration. Exclusion Criteria: Females who are pregnant, attempting to conceive, or breastfeeding. Subjects with known hypersensitivity to study drug. Subjects with very severe acne (PGA score of 5) Subjects with overt signs of skin atrophy, telangiectasias or other skin findings that would affect efficacy evaluation.

Subjects who have received systemic antibiotics within 2 weeks. Subjects using systemic corticosteroids or immunosuppressants within 28 days of entering the study. Subjects who have received any topical therapies for acne vulgaris within 2 weeks of entering the study. Subjects taking birth control pills for less than 3 months or solely for the prevention of acne. Subjects who are currently participating in or, within the previous 28 days, have participated in another study for the treatment of acne vulgaris. Subjects with clinical conditions that may post a health risk to the subject by being involved in the study or detrimentally affect regular follow-up of the subject.
