What this trial studies

This study evaluates the effects of topical imipramine when used alongside photodynamic therapy (PDT) to treat actinic keratosis in veterans. PDT is a standard treatment for precancerous skin lesions, and this research aims to determine if imipramine can mitigate the immunosuppressive effects of PDT, potentially enhancing its efficacy. Participants will be recruited from the Dayton VA Medical Center, where they will receive both treatments under careful monitoring. The study focuses on adult patients with fair skin types who have been prescribed PDT for their skin conditions.

Who should consider this trial

Good fit: Ideal candidates are adult males and females aged 18 and older with fair skin types who have been prescribed PDT for actinic keratosis.

Not a fit: Patients currently taking tricyclic antidepressants or selective serotonin reuptake inhibitors, or those with certain skin conditions or active rashes, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes for veterans with actinic keratosis by enhancing the effectiveness of photodynamic therapy.

How similar studies have performed: While PDT is a well-established treatment, the combination with topical imipramine has not been previously evaluated, making this a novel approach.
