Study summary

A Randomized, Double-Blind, Placebo-Controlled, Parallel-Design, Multiple-Site Clinical Study to Evaluate the Therapeutic Equivalence and Safety of adapalene and benzoyl peroxide gel, 0.3%/2.5% (Actavis Laboratories UT, Inc.) to Epiduo® Forte (adapalene and benzoyl peroxide) gel 0.3%/2.5% (Galderma) in the treatment of Acne Vulgaris

Read the detailed description

Up to 1000 patients 12 to 40 years of age inclusive will be enrolled to have 870 patients in the modified intent-to-treat (mITT) population and 579 patients in the per-protocol (PP) population. The primary inclusion criteria are the presence of ≥ 20 inflammatory lesions (papules and pustules) and ≥ 25 non-inflammatory lesions (opened and closed comedones) and ≤ 2 nodulocystic lesions (i.e., nodules and cysts) on the face and an Investigator's Global Assessment (IGA) score of 3 or 4.

Eligible patients will be randomized in a 1:1:1 ratio to one of the three treatments (Test, Reference or Placebo) on Visit 1. Patients will be instructed to apply the first treatment on the evening of enrollment into the study and then continue to apply once daily for the next 83 days (for a total 84 days). Patients will attend the following scheduled clinic visits:

  • Visit 1 - Screening/Baseline: Day 1
  • Visit 2 - Interim Visit: Day 28 ± 4
  • Visit 3 - Interim Visit: Day 56 ± 4
  • Visit 4 - End of Study: Day 85 ± 4 Efficacy evaluations will be based on dermatological assessments in the clinic. The primary statistical analyses of interest are (1) the percent change from baseline to Week 12 in the number of inflamed (papules/pustules) lesions and non-inflamed (open and closed comedones) lesions. In addition, patients will also be evaluated by the Investigator to determine "Clinical Success" or "Clinical Failure" at Week 12

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Male or non-pregnant, non-lactating female, ≥ 12 and ≤ 40 years of age with a clinical diagnosis of acne vulgaris.
  2. Signed form that meets all criteria of current FDA regulations. For a patient considered to be a minor in the state he/she lives and is enrolled, the patient parent or legal guardian will be required to sign the consent form and the patient will sign an IRB approved "assent to participate" form.
  3. Females of child bearing potential must not be pregnant or lactating at Visit 1 (as confirmed by a negative urine pregnancy test with a sensitivity of less than 25 mlU/mL or equivalent units of human chorionic gonadotropin). Women of must agree to the use of a reliable method of (e.g., total abstinence, IUD, a double-barrier method [such as condom plus diaphragm with spermicide], oral, transdermal, injected or implanted non- or hormonal contraceptive), throughout the study. If the female is using a hormonal contraceptive, the same product must be taken for 3 months prior to Visit 1 and must agree not to replace with some other hormonal contraceptives during the study. A sterile sexual partner is not considered an adequate form of birth control.

    All females will be considered to be of childbearing potential unless they:

    • Are , defined as women who have been amenorrheic for at least 12 consecutive months, without other known or suspected primary cause.
    • Have been sterilized surgically or who are otherwise proven sterile (i.e., total hysterectomy, or bilateral oophorectomy) with surgery at least 4 weeks prior to Screening. Tubal ligation will not be considered a surgically sterile method.

    Female patients of childbearing potential are defined as:

    • Females without prior hysterectomy, or who have had any evidence of menses in the past 12 months.
    • Females who have been amenorrhea for ≥ 12 months, but the amenorrhea is possibly due to other causes, including prior chemotherapy, anti-estrogens, or ovarian suppression.
  4. Have facial acne vulgaris with: ≥ 20 inflammatory lesions (i.e., papules and pustules) and ≥ 25 non-inflammatory lesions (i.e., open and closed comedones) and ≤ 2 nodulocystic lesions (i.e., nodules and cysts).
  5. Have an Investigator's Global Assessment (IGA) score of 3 or 4 (see Appendix A).
  6. Willing to comply with the study requirements and restrictions including refraining from the use of all other topical acne medications or antibiotics during the 12 week treatment period.
  7. Patients who use make-up must have used the same brands/types for a minimum period of 14 days before study entry and must agree to not change brand/type or frequency of use throughout the study.

Exclusion criteria

Exclusion Criteria:

  1. Patient has more than 2 facial nodular lesions; any nodules present will be documented but not included in the inflammatory and non-inflammatory lesion count for analysis.
  2. Patient has active cystic acne.
  3. Patient has acne conglobata, acne fulminans, or acne vulgaris requiring systemic treatment.
  4. Patient has a skin condition that would interfere with the diagnosis or assessment of acne vulgaris (e.g., on the face: rosacea, dermatitis, psoriasis, squamous cell carcinoma, eczema, acneform eruptions caused by medications, acne, steroid folliculitis, bacterial folliculitis).
  5. Patients with excessive facial hair such as beards, sideburns, moustaches, etc. that would interfere with the diagnosis or assessment of acne.
  6. Patients with tattoos or excessive facial scarring that, in the Investigator's opinion, may interfere with the evaluation of the patient's acne.
  7. Patients with active facial sunburn, peeling from sunburn, or patients that will be exposed to excessive sunlight during the study.
  8. Females who are pregnant, lactating or likely to become pregnant during the study.
  9. History of allergy or to adapalene, retinoids, benzoyl peroxide or history of any drug hypersensitivity or intolerance that, in the Investigator's opinion, would compromise the safety of the patient or the study.
  10. 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.

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 23, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
