  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Subject was male or female, 18 years of age or older.
  • Subject provided written informed consent.
  • Subject was willing and able to apply the test article as directed, comply with study instructions and commit to all follow-up visits for the duration of the study.
  • Subject had a clinical diagnosis of actinic keratoses (AK) with at least five (5) and no more than 20 clinically typical, visible or palpable AK lesions, each at least 4mm in diameter, in an area greater than 25cm2 on the face (excluding ears) or balding scalp, but not both.

Abstinence was an acceptable form of birth control for subjects who were not sexually active. Subjects who became sexually active during the trial had to agree to use an effective, non-prohibited form of birth control for the duration of the study.

  • Subject had used oral corticosteroid therapy, interferon, cytotoxic drugs, immunomodulators, immunosuppressive therapies or retinoids within one month prior to the Baseline Visit.
  • Subject had used topical medications, corticosteroids, alpha hydroxy acids (e.g., glycolic acid, lactic acid etc. > 5%), beta hydroxy acid (salicylic acid > 2%), urea >5%, 5-fluorouracil, diclofenac, imiquimod or prescription retinoids (e.g., tazarotene, adapalene, tretinoin) to the face or balding scalp within one month prior to the Baseline Visit.

About this study

Official title: A Multicenter, Randomized, Double-Blind, Vehicle-Controlled, Parallel Group Comparison Study to Determine the Therapeutic Equivalence of Generic Imiquimod Cream, 3.75% and Zyclara™ (Imiquimod) Cream, 3.75% in Subjects With Actinic Keratoses

Zyclara™ (imiquimod) Cream, 3.75% is approved by the FDA for the treatment of actinic keratoses on the full face or balding scalp. Zyclara is applied once daily for two, 2-week treatment cycles separated by a 2-week no treatment applied interval. A generic imiquimod cream, 3.75% has been developed by Actavis Mid-Atlantic LLC for the topical treatment of clinically typical, visible or palpable actinic keratoses (AK) of the full face or balding scalp.

The current clinical study is designed to evaluate the therapeutic equivalence of this formulation with the currently marketed Zyclara™ (imiquimod) cream, 3.75% formulation (Graceway Pharmaceuticals LLC).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Complete clearance rate

    Complete clearance rate (treatment success) was defined as the proportion of subjects in a treatment group with 100% clearance of all AK lesions within the Treatment Area. The primary efficacy endpoint was the proportion of subjects in the per-protocol (PP) population with treatment success at Week 14/EOS. All AKs (Baseline and new lesions), independent of size, within the Treatment Area were included in the AK lesion counts.

    Measured: 8 weeks post treatment period

  2. Dosing Compliance

    Measures of test article compliance included the total number of days of test article applications recorded on the CRFs and verified from the data in the subject diaries. Compliant subjects were defined as those who applied at least 75% and no more than 125% of the test article applications.

    Measured: 8 weeks post treatment period

  3. Adverse Events

    The severity and frequency of adverse events (AEs) were assessed in the three treatment groups.

    Measured: 14 weeks

  4. Local Skin Reactions

    The severity and frequency of local skin reactions (LSRs) were assessed in the three treatment groups.

    Measured: 14 weeks

Secondary outcomes (2)
  1. Partial Clearance Rate

    Partial clearance rate was defined as the proportion of subjects in a treatment group with 75% or more reduction in the AK count in the Treatment Area at Week 14/EOS as compared to Baseline.

    Measured: 8 weeks post treatment

  2. Percent Change in the AK number

    Percent change in the AK number as compared to Baseline at Week 14/EOS was a secondary outcome.

    Measured: 8 weeks post treatment

Questions about this trial

What is this clinical trial studying?

A study testing imiquimod cream, 3.75% in people with Actinic Keratoses, run by Actavis Mid-Atlantic LLC at 19 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Dec 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 19 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Complete clearance rate (time frame: 8 weeks post treatment period). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Dec 2011.
