Summary
The purpose of this study is to explore the effect of treating actinic keratoses of the face
with imiquimod 3. 75% cream followed by photodynamic therapy in comparison to treatment with
imiquimod alone
Clinical Details
Official title: An Exploratory, Open-label Study of Sequential Field-directed Treatment of Actinic Keratoses of the Face With Imiquimod 3.75% Cream Followed by Photodynamic Therapy

Primary outcome: Actinic Keratosis Count
Secondary outcome: Complete ClearanceCosmetic Appearance
Detailed description:
Actinic keratoses are common skin lesions associated with solar ultraviolet radiation
exposure. Some actinic keratoses may develop into skin cancers.
Imiquimod 3. 75% cream is an approved treatment for actinic keratoses that utilizes a regimen
of application to the entire face or balding scalp of up to 2 packets of cream daily for two
2-week cycles, separated by a 2-week no treatment interval.
Photodynamic therapy with aminolevulinic acid (ALA) 20% topical solution is also an approved
treatment for actinic keratoses. ALA is applied to actinic keratoses, and after an
incubation period, is excited with light. Although approved as a lesion-directed treatment
for actinic keratoses, treatment of a field (e. g. face) with photodynamic therapy is
commonly performed.
Treatment with photodynamic therapy followed by imiquimod 5% cream has been reported in
patients with actinic keratoses, basal cell carcinoma and Bowen's disease, and treatment
with imiquimod 5% cream followed by photodynamic therapy in patients with vulvar
intraepithelial neoplasia. There are, however, no prior studies on the safety and/or
efficacy of using topical imiquimod 3. 75% in conjunction with photodynamic therapy in the
treatment of actinic keratoses.
This study will use an open-label parallel cohort design in which all patients will received
treatment with imiquimod 3. 75% cream, and subsequently will be randomized to either
photodynamic therapy or observation.
