What is this trial about?

One of the main success factors in acne therapy is user compliance with treatment, product cost, availability and ease of use. Poor compliance may translate into decreased efficacy (either not improving symptoms well enough or not improving symptoms fast enough), tolerability issues or adverse effects (eg, erythema, dryness, or peeling of the skin), a lack of understanding of the instructions for use, or product cost/availability. Whatever the reason, poor compliance translates to decreased efficacy and increased frustration on the part of the user. The current study will evaluate and compare the efficacy and tolerability of 2 over-the-counter, topical benzoyl peroxide (BPO) product lines in subjects with acne: MAXCLARITY II (2.5% BPO) Foam Cleanser and Foam Treatment and (0.5% Salicylic Acid) Toner Foam compared with PROACTIV (2.5% BPO) Renewing Cleanser and Repairing Lotion and Revitalizing Toner.

What are the participation requirements?

Yes

Inclusion Criteria

1. Capable of understanding and willing to provide signed and dated written voluntary informed consent (and any local or national authorization requirements) before any protocol specific procedures are performed.

2. Male or female aged from 16 to 29 years, inclusive, at time of consent. No more than 50% of the subjects at each site can be enrolled under the age of 20.

3. Mild facial acne vulgaris, characterized by at least 12 facial inflammatory lesions (papules and pustules) and/or noninflammatory lesions (open and closed comedones) on the face.

4. Able to complete the study and to comply with study instructions.

5. Sexually active females of childbearing potential participating in the study must agree to use a medically acceptable method of contraception while receiving protocol-assigned product. A woman of childbearing potential is defined as one who is biologically capable of becoming pregnant; including perimenopausal women who are less than 2 years from their last menses. Acceptable contraceptive methods include the following:

- Hormonal contraception, including oral, injectable, or implantable methods started at least 2 months prior to screening. If hormonal contraception was started less than 2 months prior to screening, then a form of nonhormonal contraception should be added until the third continuous month of hormonal contraception has been completed.
- Two forms of reliable nonhormonal contraception, to include the use of either an intrauterine device plus a reliable barrier method or 2 reliable barrier methods. Reliable barrier methods include condoms or diaphragms. A cervical cap is also a reliable barrier method, provided that the female subject has never given birth naturally. The combined use of a condom and spermicide constitute 2 forms of acceptable nonhormonal contraception, provided that they are both used properly. The use of spermicide alone and the improper use of condoms are inferior methods of contraception. Subjects with surgical sterilization, including tubal sterilization or partner's vasectomy, must use a form of nonhormonal contraception. A barrier method or sterilization plus spermatocide is acceptable.
- Women who are not currently sexually active must agree to use a medically accepted method of contraception should she become sexually active while participating in the study.
No
