Brief Summary
Multi-center, single-blind, randomized, comparative, split-face study. The duration of the study is 8 weeks. Commencing at baseline, subjects will apply once daily both clindamycin and benzoyl peroxide gel and benzoyl peroxide/adapalene gel in a bilateral split-face fashion (allocation to left and right side randomly assigned) for an initial 2 weeks. After visit 3, subjects will commence application of clindamycin and benzoyl peroxide gel to the entire face for an additional 6 weeks.

Outcome Measures
Primary Outcomes (4)
Skin Dryness Score
Investigator assessment of tolerability (skin dryness) on the face. Erythema, peeling, and dryness were graded using the following Investigator Assessment of Tolerability scale: 0, None; 1, Slight; 2, Moderate; 3, Intense.
Week 1, Week 2
Skin Peeling Score
Investigator assessment of tolerability (skin peeling) on the face. Erythema, peeling, and dryness were graded using the following Investigator Assessment of Tolerability scale: 0, None; 1, Slight; 2, Moderate; Intense, 3.
Week 1, Week 2
Irritant/Allergic Contact Dermatitis Score
Signs and symptoms of tolerability (erythema, peeling, dryness, and irritant/allergic contact dermatitis) on the face. Erythema,peeling, and dryness were graded using the following scale: 0 None 1. Slight 2. Moderate 3. Intense
Week 1, Week 2
Erythema (Redness) Score
Investigator assessment of tolerability (irritant/allergic contact dermatitis) on the face. Erythema, peeling, and dryness were graded using the following Investigator Assessment of Tolerability scale: 0, None; 1, Slight; 2, Moderate; 3, Intense.

Study Arms (2)
Duac gel
EXPERIMENTALSubjects will apply Duac gel once a day to one-half of their face and and apply Epiduo gel on the other side of their face once daily for the first 2 weeks.
Epiduo gel
ACTIVE COMPARATORSubjects will apply Duac gel once a day to one-half of their face and and apply Epiduo gel on the other side of their face once daily for the first 2 weeks.
Interventions
Subjects will apply Duac(clindamycin and benzoyl peroxide) gel to one-half of their face and and apply Epiduo (benzoyl peroxide/adapalene) gel on the other side of their face once a day for the first 2 weeks. Starting at week 2, subjects will apply Duac (benzoyl peroxide/clindamycin gel) to the entire face for an additional 6 weeks.

Eligibility Criteria
You may qualify if:
- Male or female subjects at least 18 years of age, in good general health with documented diagnosis of facial acne vulgaris.
- Sexually active females of childbearing potential participating in the study must agree to use a medically acceptable method of contraception while receiving protocol-assigned product.
- Subjects willing to follow therapeutic instructions including avoidance of any other topical facial or systemic acne therapy during the conduct of the study.
- Capable of understanding and willing to provide signed and dated written voluntary informed consent before any protocol specific procedures are performed.
You may not qualify if:
- Female subjects who are pregnant, trying to become pregnant or breastfeeding.
- Subjects who have any clinically relevant finding at their baseline physical examination or medical history such as severe systemic diseases, diseases of the facial skin, other than acne vulgaris.
- Facial hair that may obscure the accurate assessment of acne grade.
- History or presence of regional enteritis or inflammatory bowel disease (e.g., ulcerative colitis, pseudomembranous colitis, chronic diarrhea, or a history of antibiotic-associated colitis) or similar symptoms.
- Use of topical antibiotics on the face and systemic antibiotics within the past 2 and 4 weeks, respectively.
- Use of topical corticosteroids on the face or systemic corticosteroids within the past 4 weeks. Use of inhaled, intra-articular or intra-lesional (other than for facial acne lesions) steroids is acceptable.
- Use of systemic retinoids within the past 6 months.
- Concurrent use of drugs known to be photosensitizers (e.g., thiazides, tetracyclines, fluoroquinolones, phenothiazines, sulfonamides) because of the possibility of increased phototoxicity.
- Concomitant use of neuromuscular blocking agents. Clindamycin has neuromuscular blocking activities, which may enhance the action of other neuromuscular blocking agents.
- Use of topical anti-acne medications within the past 2 weeks.
- Use of any investigational drugs or treatments during the study or within 4 weeks of the baseline visit.
