About this study
Official title: A Split-face, Paired-comparison, Pilot Study to Evaluate Safety and Efficacy of Two Topical Benzoyl Peroxide 10.0% Creams for Mild to Moderate Acne Vulgaris
This study is a split face, paired-comparison, pilot study of 10 subjects. Participants in this study will be patients seen at Children's Memorial Hospital, who are clinically diagnosed with mild to moderate acne vulgaris. Participants will be recruited from the clinic, as well as advertising and from previous Institutional Review Board (IRB) approved acne studies housed in the Department of Dermatology. All subjects accrued from previous studies have agreed to be contacted for further investigations. Subjects 13 to 35 years of age with mild to moderate acne vulgaris symmetrical in appearance on both sides of the face, and meeting inclusion criteria will be eligible to participate.
Read the detailed description
Acne vulgaris is a follicular disorder occurring in pilosebaceous units in the skin of the face, neck, and upper trunk. These sebaceous follicles have follicular channels and adjacent multiacinar sebaceous glands. In the lubrication process of normal skin, sebum travels through the follicular canal to the skin surface, carrying along with it desquamated cells from follicular epithelium. Acne develops when these specialized follicles undergo pathologic alterations that result in the formation of non-inflammatory lesions (comedones) and inflammatory lesions (papules, pustules, and nodules).
The basic cause of acne remains unknown, but its manifestations are thought to be the product of four pathogenic events: 1) increased sebum production fueled by androgenic stimulation in the pubertal period; 2) obstruction of the pilosebaceous unit due to an abnormal keratinization process; 3) proliferation of Propionibacterium acnes, an anaerobic diptheroid normally residing in pilosebaceous follicles; and 4) inflammation that is mediated both by the action of chemotactic factors and various enzymes, and initiated in part by the interaction of P. acnes with toll-like receptors. Impaction of the pilosebaceous follicle gives rise to the microcomedo that is thought to be the precursor lesion of acne.
Topical benzoyl peroxide is a common and well-established agent with known antibacterial and antimicrobial properties used in the treatment of acne vulgaris. The safety profile for topical benzoyl peroxide has been well delineated. The most common side effects attributed to benzoyl peroxide products include irritation, dryness, scaling, burning and stinging.
Benzoyl peroxide 10.0% creams (Formulation #1 and Formulation #2) will be evaluated to detect any differences in their response for safety and efficacy.

Also called Benzoyl Peroxide 10% Cream
Formulation 1 will be applied to the randomly-assigned single (left or right) side of the face twice daily.
| Study group | Role | What they receive |
|---|---|---|
| Left side of face | Experimental | Topical benzoyl peroxide 10.0% cream - Formulation 2 or Topical benzoyl peroxide 10.0% cream - Formulation 1 is to be applied to left side of the face.

Receives: Drug: Topical benzoyl peroxide 10.0% cream - Formulation 1; Drug: Topical benzoyl peroxide 10.0% cream - Formulation 2 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Inflammatory Lesions (Papules and Pustules)
Assessment will be done based on lesion counting. We will compare the lesions treated twice daily with the benzoyl peroxide 10.0% cream Formulation #1 vs. the benzoyl peroxide 10.0% cream Formulation #2.
Measured: 4 Weeks

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 17 Nov 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Inflammatory Lesions (Papules and Pustules) (time frame: 4 Weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 May 2015.
