This is an interventional treatment trial for Acne Vulgaris
Eligibility Criteria
Inclusion Criteria:
- Documented diagnosis of acne vulgaris.
- Lesion count: 20 to 50 inflammatory (papules and pustules) and 30 to 100 noninflammatory (open and closed - comedones) facial lesions excluding nose, and ≤ 1 small nodular lesion. Cystic lesions are not allowed at baseline.
- Investigator Static Global Assessment of 3 or 4 at Baseline.
Exclusion Criteria:
- Clinically relevant finding at baseline or medical history of severe systemic diseases or diseases of the facial skin, other than acne vulgaris.
- Subjects with cystic acne lesions.
- Facial hair that may obscure the accurate assessment of acne grade.
- History or presence of regional enteritis or inflammatory bowel disease (eg, ulcerative colitis, pseudomembranous colitis, chronic diarrhea, celiac disease or a history of antibiotic-associated colitis) or similar symptoms.
- Concurrent use of medications known to be photosensitizers (eg, thiazides, tetracyclines, fluoroquinolones, phenothiazines, and 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.

5. Study Description
Brief Summary
A single-blind (investigator-blinded), randomized, parallel group, single center study to evaluate the tolerability and efficacy of combination therapy with Duac Gel / 0.1% Tazorac Cream and Acanya Gel / 0.1% Tazorac Cream for the treatment of facial acne vulgaris.
Detailed Description
This is a single-blind (investigator-blinded), randomized, parallel group, single center study to evaluate the tolerability and efficacy of combination therapy with Duac Gel/Tazorac Cream and Acanya Gel/Tazorac Cream for the treatment of facial acne vulgaris. Approximately 40 male and female subjects will be enrolled (20 per study group).
Subjects will participate in the study for 12 weeks; visits will be scheduled at baseline and at weeks 1, 2, 4, 8, and 12 (total of 6 visits). Eligible subjects will be randomized at baseline to 1 of the 2 study groups in a 1:1 ratio (Duac Gel/Tazorac Cream to Acanya Gel/Tazorac Cream). Subjects will apply either Duac Gel or Acanya Gel to the face each morning and apply Tazorac Cream to the face each evening.
Tolerability will be evaluated through subject assessments of burning/stinging, itching, and oiliness and through investigator assessments of peeling, erythema, and dryness. In addition, subjects will evaluate their overall skin comfort and record the usage of moisturizer and sunscreen, if needed. Efficacy will be assessed through lesion counts (total, inflammatory and noninflammatory) and ISGA. Safety will be assessed by evaluating adverse events (AEs), concomitant medication use, and withdrawals from the study.
This is an investigator-blinded study; therefore, subjects and study-center staff will not be blinded to study treatment allocation. Subjects (and parents or legal guardians) and study-center staff will be instructed not to reveal study product allocation to the investigator.
