Brief Summary

EPIDUO™ (adapalene and benzoyl peroxide) Gel 0.1%/2.5%, marketed by GALDERMA LABORATORIES, L.P., is a safe and effective topical therapy used for the treatment of acne vulgaris. Actavis Mid-Atlantic LLC has developed a generic formulation of adapalene and benzoyl peroxide topical gel 0.1%/2.5%,and the current study is designed to evaluate the safety and efficacy of this formulation to determine if it is bioequivalent to EPIDUO™.

Conditions

Acne Vulgaris

Keywords

acne; adapalene/benzoyl peroxide; Epiduo; Mild to severe acne vulgaris

Outcome Measures

Primary Outcomes (3)

• Percent change in inflammatory and non-inflammatory lesions from Baseline to Week 12

  The mean percent change from Baseline to Visit 5 (End of Treatment) in the inflammatory and non-inflammatory lesion counts.

  Week 12

• Treatment-emergent adverse events

  All adverse events (AEs) and treatment-emergent AEs reported during the study were summarized for the safety assessment. A treatment-emergent AE was defined as any event not present prior to the initiation of treatment with the investigational products or any event present at Baseline that worsened in either intensity or frequency following exposure to investigational products.

  12 Weeks

• Signs and Symptoms of Local Irritation

  Patients will be evaluated for any signs and/or symptoms as separate scores of local irritation, including: erythema, dryness, burning / stinging, erosion, edema, pain, scaling, and itching using the following scale: 0 = None 1. = Mild, barely perceptible 2. = Moderate, distinctive presence 3. = Severe, marked/intense

  12 Weeks

Secondary Outcomes (2)

• The proportion of "success" patients at Visit 5 using the IGE

  12 Weeks

• Mean Percent Change in Total Lesion Count from Baseline to Visit 5

  12 Weeks

• Patients must have a definite clinical diagnosis of mild to severe acne vulgaris (Grade 2, Grade 3 or Grade 4 on the IGE).
• Patients must have a minimum of 20 inflammatory lesions and a maximum of 100 and a minimum of 25 and a maximum of 100 non-inflammatory lesions (i.e., open and closed comedones) and no more than 2 nodulocystic lesions (i.e., nodules and cysts) at baseline. For the purposes of study treatment and evaluation, these lesions should be limited to the facial treatment area. Lesions involving the eyes, angles of the nose (i.e., the lines around your nostrils and under the nostrils) and scalp should be excluded from the count. Patients may have acne lesions on other areas of the body (e.g., on the back).
• Female patients of childbearing potential must have been using accepted methods of birth control or must agree to continue to practice abstinence, from 30 days prior to study entry to 30 days after the last administration of study drug. All female patients are considered to be of childbearing potential unless they have been surgically sterilized or have been postmenopausal for at least 1 year. Abstinence is an acceptable method of birth control. Any of the following methods of birth control are acceptable: oral contraceptives, contraceptive patches/implants (e.g., Norplant®) Depo-Provera®, double barrier methods (e.g., condom and spermicide) or IUD. Female patients must have a negative urine pregnancy test at baseline. A negative result of a pregnancy test having a minimum sensitivity of at least 50 mIU/ml for hCG should be obtained.
• All male patients must agree to use accepted methods of birth control with their partners, from the day of the first dose administration to 30 days after the last administration of study drug. Abstinence is an acceptable method of birth control. Any of the following methods of birth control are acceptable: oral contraceptives, contraceptive patches/implants (e.g., Norplant®), Depo-Provera®, double barrier methods (e.g., condom and spermicide) or IUD.
• Patients must be willing and able to understand and comply with the requirements of the protocol, including attendance at the required study visits.
• Patients must be willing to refrain from using any other treatments for acne vulgaris, including antibiotics, other than the investigational product, for acne present on the face.
