Primary Outcome Measures:
  • Adherence to Study Medication [ Time Frame: Baseline to 6 weeks ] [ Designated as safety issue: No ]
    Adherence will be reported as percentage of prescribed doses taken as measured electronically by a Medication Event Monitoring System (MEMS®) cap.


Secondary Outcome Measures:
  • Change in Acne Global Assessment [ Time Frame: Baseline and 6 weeks ] [ Designated as safety issue: No ]
    Change in the physician's global assessment of acne severity on a validated 0-5 scale (0=clear to 5=very severe) from baseline to Week 6 visit.

  • Change in Acne Lesion Count [ Time Frame: Baseline and 6 weeks ] [ Designated as safety issue: No ]
    Change in total count of acne lesions from baseline visit to Week 6 visit

  Eligibility

Ages Eligible for Study:   12 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male or female subject with mild to moderate acne, aged 12 and older, who agrees to participate and provides written consent.
  • Have an Acne Global Assessment (AGA) of mild to moderate acne (an AGA score of 2 or 3)

Exclusion Criteria:

  • Presence of a concurrent medical condition or skin condition, which is determined by the investigator to potentially interfere with study outcomes or patient assessments.
  • Subjects with known allergy or sensitivity to Epiduo® Gel (or Benzoyl Peroxide Gel) or components therein, including adapalene or benzoyl peroxide
  • Female subjects who are not postmenopausal for at least 1 year, surgically sterile, or willing to practice effective contraception during the study. Reliable methods of birth control are: abstinence (not having sex), oral contraceptives, intrauterine device (IUD), Depo-Provera, tubal ligation, or vasectomy of the partner (with confirmed negative sperm counts) in a monogamous relationship (same partner). An acceptable, although less reliable, method involves the careful use of condoms and spermicidal foam or gel and/or a cervical cap or sponge. Nursing mothers, pregnant women and women planning to become pregnant while on study are to be excluded.
