About this study

Official title: A Phase 3, Randomized, Double-blinded, Placebo-controlled, Multicenter, Efficacy and Safety Study of Six Weeks of Treatment With Imiquimod Creams for Actinic Keratoses

The purpose of this study is to determine whether imiquimod creams are effective in treating Actinic Keratoses when applied to the face or balding scalp.

Actinic keratosis (AK) is a skin condition that shows up on skin routinely exposed to the sun, such as the face, scalp, shoulders, chest, back, arms, and hands. The active ingredient contained in the study cream for this study is the same as that of the approved product Aldara, which has shown to be safe and effective for the treatment of AKs.

Read the detailed description

These were a randomized, double-blind, multicenter, placebo-controlled studies that compared the efficacy and safety of 2.5% imiquimod cream and 3.75% imiquimod cream with that of placebo in the treatment of typical visible or palpable AK of the face or balding scalp. Subjects were scheduled for a total of 11 visits (1 prestudy screening visit and 10 on-study visits). Subjects determined to be eligible during the screening phase were randomized in a 1:1:1 ratio to 2.5% imiquimod cream, 3.75% imiquimod cream, or placebo cream. The creams were applied daily for 2 treatment cycles. The first treatment cycle consisted of 3 weeks of daily treatment followed by 3 weeks of no treatment, and the second treatment cycle consisted of an additional 3 weeks of daily treatment followed by 8 weeks of no treatment. The investigator selected the treatment area for the study (either the entire face or the entire balding scalp, but not both). Subjects applied a thin layer of cream to the treatment area (up to 2 packets, or 500 mg of product, per application), avoiding the periocular areas, lips, and nares. Study medication was applied prior to normal sleeping hours and removed approximately 8 hours later with mild soap and water. Ears were excluded from both assessment and treatment. Rest periods from daily treatment were instituted by the investigator as needed to manage local skin reactions (LSRs) or application site reactions, with resumption of treatment upon adequate resolution as determined by the investigator.

The duration of each subject's study participation was approximately 21 weeks, including a 4-week maximum screening period and a 17-week study period. At the End of Study (EOS) visit, eligible subjects may have been invited to participate in a separate study evaluating AK recurrence.

What is being measured

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

  1. Number of Participants With Complete Clearance of AK Lesions

    Subject status with respect to complete clearance of AK lesions at End of Study (EOS), ie, the Week 17 visit. Complete clearance was defined as the absence of clinically visible or palpable AK lesions in the treatment area. All lesions within the identified treatment area were included in the count, even if the lesion was a new lesion or "subclinical" lesion that had not been identified at Baseline.

    Measured: End of Study the Week 17 visit

Secondary outcomes (3)
  1. Number of Participants With Partial Clearance of AK Lesions

    Subject status with respect to complete clearance of AK lesions at End of Study (EOS), defined as at least a 75% reduction in the number of AK lesions in the treatment area compared with Baseline.

    Measured: End of Study the Week 17 visit

  2. Percent Change From Baseline in AK Lesion Count

    Percent change from Baseline to end of study (EOS) in investigator counts of AK lesions. A negative percent change is better than a positive percent change.

    Measured: At all visits - Baseline through the Week 17 EOS visit

  3. Local Skin Reactions (LSR)

    Six local skin reaction (LSR) signs were predefined and were assessed for presence and intensity at each visit. These included: Erythema, edema, Weeping/Exudate, Flaking/Scaling/Dryness, Scabbing/Crusting and Erosion/Ulceration. The LSRs were scored as 0=none, 1=mild, 2=moderate, 3=severe. Summary of LSR - area under the curve (AUC) of sum of LSR scores (days).

    Measured: The time period for the AUC extends to 8 weeks after the end of treatment (Week 17)

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 4 inclusion and 4 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 29 Jun 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 26 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Jun 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Complete Clearance of AK Lesions (time frame: End of Study the Week 17 visit). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00603798, which also lists 1 linked publication.

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 29 Jun 2010.
