About this study

Official title: A Phase 3b Randomized, Double-blinded, Placebo-controlled, Multicenter, Efficacy and Safety Study of Imiquimod Cream Following Cryosurgery for the Treatment of Actinic Keratoses

The objective of this study is to evaluate the efficacy and safety of imiquimod cream versus placebo cream when used after cryosurgery in the treatment of actinic keratoses (AKs).

Read the detailed description

In this multicenter, randomized, double-blind, placebo-controlled study, the efficacy and safety of imiquimod 3.75% cream following cryosurgery to treat clinically typical visible or palpable AK lesions on the face was compared with that of placebo cream. Based on a 1:1 randomization, approximately 120 subjects applied imiquimod 3.75% cream daily (up to 500 mg cream daily [18.75 mg imiquimod]) and approximately 120 subjects applied placebo cream daily during two 2-week periods (Cycle 1 and Cycle 2) separated by 2 weeks of no treatment. Subjects visited the clinic 9 times-1 screening/cryosurgery visit (additional visits might be needed during the screening period to assess healing from the cryosurgery), 4 treatment visits(treatment initiation at Weeks 0 and 4 and treatment follow-up at the end of Weeks 2 and 6), and 4 posttreatment visits (4, 8, 14, and 20 weeks after the last administration of study treatment at the end of Week 6). The total study duration for a subject, including a 2-week screening period, was up to 28 weeks.

Prior to cryosurgery, subjects had to have ≥10 clinically typical visible or palpable AK lesions in an area that exceeded 25 cm^2 on the face to be eligible for participation in the study. At screening, a minimum of 5 visible lesions were not treated with cryosurgery, and 5 to 14 visible lesions were treated with cryosurgery. Subjects had to have at least 5 AK lesions after the skin healed sufficiently from the cryosurgery to be eligible for randomization to either imiquimod 3.75% or placebo cream. Subjects applied up to 2 packets of study cream (500 mg total) as a thin layer to the entire face, avoiding the periocular areas, lips, and nares; ears were excluded from both assessment and treatment. Study cream was applied prior to normal sleeping hours and removed approximately 8 hours later with mild soap and water. Rest periods from daily treatment could be approved by the investigator as needed, with treatment resumption at the investigator's discretion.

What is being measured

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

  1. Change From Baseline in Percentage of Lesion Count

    The primary efficacy endpoint was a comparison between the active and placebo treatment groups of percent change from baseline in the total AK lesion count at Week 26. All AK lesions on the face were included in the analysis-treated and untreated AK lesions at baseline (defined as the AK lesion count just prior to cryosurgery) and new lesions that appeared post-baseline.

    Measured: Week 26

Secondary outcomes (2)
  1. Percent of Subjects With Complete Clearance

    Proportion of subjects who achieved complete clearance of all AK lesions, cryosurgery-treated AK lesions, and non cryosurgery-treated AK lesions from baseline to Week 26/EOS in the ITT population.

    Measured: Week 26

  2. Number of Participants With Any Post-baseline Local Skin Reactions (LSRs)

    LSRs were assessed independently from AEs. The frequency and percentage of subjects, as well as the mean (SD) and median score for severity (none=0, mild=1, moderate=2, and severe=3), were summarized by treatment group and by visit for the following LSRs: erythema, edema, weeping/exudates, flaking/ scaling/dryness, and scabbing/crusting. Erosion and ulceration were also evaluated (none=0, erosion=1, and ulceration=2). A score of greater than 0 for the specified LSR was considered a "treatment site reaction".

    Measured: Weeks 2, 4, 6, 10, 14, 20, and 26

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing imiquimod cream in people with Actinic Keratosis, run by Graceway Pharmaceuticals, LLC at 18 sites in 2 countries.

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 5 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 31 Aug 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in United States, Canada. 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 23 Aug 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?

Change From Baseline in Percentage of Lesion Count (time frame: Week 26). 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 31 Aug 2010.
