Primary Outcome Measures:
  • Adherence to Study Medication [ Time Frame: Baseline to 6 weeks ]
    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 ]
    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 ]
    Change in total count of acne lesions from baseline visit to Week 6 visit

Arms Assigned Interventions
Experimental: Medication with sample and demonstration
Subjects will receive a sample tube of the medication with demonstration of how to use it at the first visit.
Drug: Adapalene + benzoyl peroxide samples
A sample size tube of the study medication, combination adapalene 0.1% plus benzoyl peroxide 2.5% gel, will be provided with instruction on proper application, including demonstration, at the first visit.
Other Name: Epiduo
Drug: Adapalene + benzoyl peroxide from standard tube
Subjects are instructed to apply the combination adapalene 0.1% plus benzoyl peroxide 2.5% gel once daily to all affected areas.
Other Name: Epiduo
Active Comparator: Medication without samples
Subjects will receive the medication in a standard tube without a sample or demonstration of proper use of the medication.
Drug: Adapalene + benzoyl peroxide from standard tube
Subjects are instructed to apply the combination adapalene 0.1% plus benzoyl peroxide 2.5% gel once daily to all affected areas.
Other Name: Epiduo


Ages Eligible for Study:   12 Years and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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.
