Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Genders Eligible for Study
All
Description
Inclusion Criteria:
- Male or non-pregnant, non-lactating female, 12-40 years of age inclusive.
- Signed informed consent form, which meets all the criteria of the current FDA regulations. For patients under the age of majority in the state they are enrolled, the patient's parent or legal guardian will be required to sign the consent form and the patient will sign an IRB approved "assent to participate" form.
- If female and of child bearing potential, prepare to abstain from sexual intercourse or use reliable method of contraception during the study (i.e. condom, Intrauterine device, hormonal contraceptives). Patients on hormonal contraceptives must have been on the same hormonal contraceptive for 3 months prior to the baseline visit and continue throughout the duration of the study.
- Have moderate to severe facial acne as defines as: at least 20 but no more that 60 facial inflammatory lesions (papules and pustules) and at least 25 but no more than 100 non-inflamed lesions (open and closed comedones) and have a Physician's Global Assessment score of 3, 4, or 5.
Exclusion Criteria:
- Patient has more than 2 facial nodular lesions, any nodules present will be documented but will not be included in the inflammatory lesion count.
- Patient has active cystic acne.
- Patient has acne conglobate.
- Patient with significant facial hair such as beards or tattoos or excessive facial scarring that, in the Investigator's opinion, may interfere with the evaluation of the patient's acne.
- Patients with facial sunburn.
- Any dermatological condition other than acne vulgaris that, in the Investigator's opinion, may interfere with the evaluation of the patient's acne (e.g. rosacea, psoriasis, dermatitis).
- Females who are pregnant, lactating, or likely to become pregnant during the study.
- History of allergy or sensitivity to adapalene or other retinoids, or history of any drug hypersensitivity or intolerance which, in the Investigator's opinion, would compromise the safety of the patient or the study.
- Significant history or current evidence of chronic infectious disease, system disorder, organ disorder, or other medical condition that, in the Investigator's opinion, would place the study participant at undue risk by participation.
- Use of any topical antibiotics, topical steroids, or topical anti-inflammatory products used on the face, any oral antibiotics known to treat acne, any systemic steroids, or any systemic anti-inflammatory agents (other than the use of non-steroidal anti-inflammatory agents) within 28 days of the first dosing day.
- Use of oral isotretinoin (Accutane®) within 6 months. Use of topical tretinoin (Retin-A®), adapalene (Differin®), tazarotene (Tazorac®), or azelaic acid (Azelex®) within 28 days of the first dosing day.
- Receipt of any drug as part of a research study within 30 days prior to dosing.
- Female patients who are using hormonal contraceptives must have been on the same type and strength of hormonal contraceptive for at least 3 months prior to enrollment in the study and throughout the duration of the study.
- Patients should not use any medicated facial products (soaps, lotions, moisturizers, etc.) or other medicated facial cleansing agents for 14 days prior to study enrollment.
- Previous participation in this study.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mean Percent Reduction from Baseline in Non-Nodular Inflamed Lesion Count
Time Frame: 84 days
|
Per Protocol Population (PPP) was assessed for the mean percent reduction compared to baseline in non-nodular lesion count (papules and pustules) at Day 84.
If a patient was withdrawn from the study prior to Day 84 for lack of efficacy, then their data was carried forward for this analysis.
|
84 days
|
Mean Percent Reduction from Baseline in Non-Inflamed Lesion Count
Time Frame: 84 days
|
Per Protocol Population (PPP) was assessed for the mean percent reduction in non-inflamed lesion count (open and closed comedones) compared with baseline at Day 84.
If a patient was withdrawn from the study prior to Day 84 for lack of efficacy, then their data was carried forward for this analysis.
|
84 days
|
Safety Analysis
Time Frame: 84 Days
|
All 601 patients randomized and dispensed study drug were included in the safety analysis.
The frequency, severity, and relationship to the study drug for adverse events in each treatment group were used to compare the safety of the study medications.
|
84 Days

|
Proportion of Patients Considered a "Clinical Success" or "Clinical Failure"
Time Frame: 84 Days
|
Secondary measure of bioequivalence using the Intent-to-Treat (ITT) population.
"Clinial Success" or "Clinical Failure" is defined by the Physician's Global Assessment.
