What this trial studies

This study evaluates the effectiveness and tolerability of a holistic management approach using Lipikar Urea 30% in conjunction with Tolak® treatment for actinic keratoses on the scalp. Conducted in Germany, it involves adult participants with grade I or II lesions who meet specific inclusion criteria. The study aims to assess how the application of cosmetics may influence the microbiome of actinic keratoses and improve cosmetic outcomes. Participants are randomly assigned to either a holistic approach or standard treatment with Tolak®.

Who should consider this trial

Good fit: Ideal candidates are adults with at least four non-hypertrophic, non-hyperkeratotic actinic keratosis lesions on the scalp.

Not a fit: Patients with known intolerance to the ingredients of Tolak® or Lipikar Urea 30%, or those who have received recent treatment in the area, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the efficacy and tolerability of actinic keratoses treatments, leading to better patient outcomes.

How similar studies have performed: While there are various treatments for actinic keratoses, the specific combination of Lipikar Urea 30% with Tolak® is a novel approach that has not been extensively tested in prior studies.
