About this trial

This is an interventional treatment trial for Acne Vulgaris

Eligibility Criteria

12 Years - undefined (Child, Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Facial acne vulgaris characterized by the following: 30-100 facial inflammatory lesions; and 25-100 facial non-inflammatory lesions; stable disease, non-rapidly regressing facial acne vulgaris; and, 3 or more nodules and/or cysts (diameter of 1cm or greater). Female subjects of childbearing potential must have a negative pregnancy test at baseline and practice reliable method of contraception throughout the study

Exclusion Criteria:

  • Non-compliance with washout period; history of clinically significant anemia or hemolysis; skin disease/disorder that might interfere with diagnosis or evaluation of acne vulgaris; allergy or sensitivity to any component of the test medications

Outcomes

Primary Outcome Measures

Change From Baseline in Inflammatory Lesion Counts (Papules,Pustules, and Nodules) at Week 12
Change from baseline in inflammatory lesion count (papules, pustules and nodules) at week 12. Papules and nodules are round, solid elevations of the skin with no visible fluid; papules are smaller (less than 5 or 10 millimeters in width and depth) and nodules are larger (greater than 5 or 10 millimeters in width and depth). Pustules are small elevations of the skin containing cloudy material. A negative number change from baseline indicates a reduction in lesion counts (improvement).

Secondary Outcome Measures

Change From Baseline in Investigator Global Assessment at Week 12
Change from baseline in the Investigator Global Assessment (IGA) at week 12. The IGA is a 5-point scale used by the investigator to assess overall acne severity, where 0 equals clear skin (no evidence of acne) and 4 equals severe acne. A negative number change from baseline indicates a reduction in acne severity (improvement).
Change From Baseline in Overall Disease Severity at Week 12
Change from baseline in overall disease severity at week 12. The overall disease severity was evaluated by the investigator using a 7-point scale to rate the overall acne severity (lesions, inflammation, facial redness and skin condition), where 0=no acne lesions and 6=most severe acne. A negative number change from baseline indicates a reduction in overall acne disease severity (improvement).
Change From Baseline in Non-Inflammatory Lesion Counts (Open and Closed Comedones) at Week 12
Change from baseline in non-inflammatory lesion counts(open/closed comedones) at week 12. Comedones are small bumps on the skin (lesions) caused by acne and found at the opening of a skin pore. Open comedones (also known as blackheads) have a microscopic opening to the skin surface, while closed comedones (also known as whiteheads or "pimples") lack the opening to the skin. A negative number change from baseline indicates a reduction in lesion counts (improvement).
