Compare the Tolerance of Clindamycin 1% /Benzoyl Peroxide (BPO) 5% Gel to Clindamycin 1.2%/ BPO 2.5% Topical Medications
Two-week Study to Determine and Compare the Tolerance and Irritation Potential of Duac® Topical Gel (Clindamycin 1% and Benzoyl Peroxide 5%) to ACANYA™ Gel (Clindamycin Phosphate 1.2% and Benzoyl Peroxide 2.5%) Topical Acne Medications

Detailed Description
This is a single-blind (blinded expert grader), parallel group, randomized, half-face study being conducted at one clinical site. On 1 side of the face, the subject will apply 1 of the 2 test products, clindamycin and benzoyl peroxide 5%) or clindamycin and benzoyl peroxide 2.5%) and the other side of the face will remain non-treated to serve as a control. Approximately 25-30 male and female healthy subjects without facial acne, aged 18 to 45, will be randomly assigned to each product.
The eligible subjects (screened 3 days prior to randomization) who qualify will be entered into a 2-week treatment phase. The once-daily applications for the clindamycin and benzoyl peroxide 5%and clindamycin phosphate and benzoyl peroxide 2.5%) will be supervised at the site, Monday through Friday of each week. Subjects will apply the study product at home on Saturdays and Sundays and record the times of application on a diary card.
A blinded expert grader will rate comparative product tolerance in terms of erythema and dryness on each week day (excluding Saturdays and Sundays) during the study before study product is applied.
Instruments will be used to measure transepidermal water loss (TEWL) to assess skin moisture in order to evaluate product mildness. Instrumentation measurements of skin surface conductance will be utilized to evaluate product performance in terms of level of skin hydration.
Subjects will complete questionnaires and all adverse events will be recorded.

Erythema (Redness)
Time Frame: 14 days
|
Compare tolerability of clindamycin and benzoyl peroxide (BPO) 5% and clindamycin phosphate and benzoyl peroxide 2.5% using visual assessments by an independent blinded grader. Erythema (redness) was evaluated using the following scale: Erythema Grade Description 0 = None 2 = Mild erythema 4 = Moderate confluent erythema 6 = Marked erythema with some edema 8 = Marked erythema, edema, possible erosion |
14 days
|
Skin Dryness
Time Frame: 14 days
|
Visual Dryness was evaluated using the following scale: Grade 0 = None 2 = Slight flaking 4 = Moderate flaking/scaling 6 = Marked scaling / slight fissuring 8 Severe scaling, fissuring |

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Skin Moisture and Hydration
Time Frame: 14 days
|
To assess skin moisture and hydration using transepidermal water loss (TEWL). Results are measured on a continuous scale as grams per meters squared (m^2) per hour. Higher values indicate greater water loss/ lower skin moisture levels. Evaporative water loss measurements provide an instrumental assessment of skin barrier function(one of the layers of the skin. Damage leads to a disruption of the barrier that is accompanied by elevated water loss rates and affects skin moisture and hydration. |
14 days
|
Changes in the Skin Surface Hydration
Time Frame: 14 days
|
The ability of an alternating current to flow through the stratum corneum is an indirect measure of its water content. The value recorded is expressed in microsiemens. Higher values indicate greater levels of skin hydration. Test results were compared to measurements from the other side of the face, which was not treated instead of referring to a normal range. A normal range does not exist for this measurement. Instead, the non-treated side of the face was used as a control to determine the normal level of skin hydration. |
