• Conditions: Actinic Keratoses

• Registration Number: NCT06274320
• Lead Sponsor: Cosmetique Active International

Brief Summary

This study is conducted in one center in Germany, in adult subjects having actinic keratoses (grade I or II) lesions on the scalp and meeting specific inclusion/exclusion criteria. The purpose of the study is to evaluate a holistic management (efficacy, tolerability and lesion cosmetic outcomes) of Tolak® treatment.

Detailed Description

Actinic keratoses (AK) are chronic skin changes usually induced by UV radiation. There are numerous options to treat AK. Some of the most used field-directed therapies include topical therapy with 5-fluorouracil (5-FU) cream and photodynamic therapy. However, the treatment with 5-FU is not without side effects (erythema, pruritus, itching/burning, etc.). Therefore, in daily clinical practice, cosmetic pre- and concomitant applications of cosmetics are often recommended to increase the efficacy as well as the tolerability of Tolak®.

The aim of this randomized, evaluator blinded, controlled parallel group study conducted in compliance with the 2013 version of the Declaration of Helsinki is to determine whether and how the application of cosmetics leads to an influence on the microbiome of AK.

Statistical method: The variables will be analyzed by using the Cochran-Mantel-Haenszel (CMH) statistic, after ridit transformation with the row mean difference statistics, testing the hypothesis of equality. Each test will be two-sided, at the 0.050 significance level.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Primary Outcome Measures

Name	Time	Method
Change in lesion response rate	from baseline to Day70	It is defined as the number of completely responding lesions divided by the total number of treated lesions in each field. Complete lesion response is defined as complete disappearance of the lesion both by palpation and visual.

Secondary Outcome Measures

Name	Time	Method
Percentage change	from baseline to Day70	The lesion complete response rate is defined as the percentage of pre-existing and treated lesions at Baseline that are assessed as clear (complete disappearance of the lesion, visually and by palpation).
