NCT ID: NCT01015638

Last Updated: 2017-03-31

Results Overview

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

Participant Flow

Clinical research center. Enrollment started: 11 Aug 2009 Last patient last visit: 1 Sep 2009

Subjects who met inclusion and exclusion criteria and are willing to participate in the study were required to undergo a 3-day screening period where they will stop the use of all facial products on their face. Subjects were required to use soap free cleanser for washing their face and may apply their normal makeup.

SECONDARY outcome

Timeframe: 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.

Timeframe: 14 days

Population: ITT

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.

SECONDARY outcome

Timeframe: 2 weeks

Population: ITT

At each visit, panelists were supplied a self-assessment questionnaire. Subjects were asked to evaluate burning, stinging, pain, and dryness in this questionnaire. Each symptom was rated with the following scale: 0 - None, 1 - Slight, 2 - Moderate, or 3 - Severe. The subjects completed this questionnaire prior to their daily application. The subjects used the time period (last 24 hours), from their last study application to the time they are administered this questionnaire for rating each symptom. The results for assessment of burning are presented here.

SECONDARY outcome

Timeframe: 2 Weeks

At each visit, panelists were supplied a self-assessment questionnaire. Subjects were asked to evaluate blistering, burning, stinging, and dryness in this questionnaire. Each symptom will be rated with the following scale: 0 - None, 1 - Slight, 2 - Moderate, or 3 - Severe. The subjects completed this questionnaire prior to their daily application. The subjects used the time period (last 24 hours), from their last study application to the time they are administered this questionnaire for rating each symptom. The results for assessment of blistering are presented here.
