Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with fair skin types and a physician's recommendation for PDT due to actinic keratosis.

Probably not a fit

Patients currently taking tricyclic antidepressants or selective serotonin reuptake inhibitors, or those with conditions that may interfere with PDT, will not benefit from this study.

What this trial studies

This study tests the combination of topical Imipramine and photodynamic therapy (PDT) to assess its effect on pain management for patients with actinic keratosis. PDT is a standard dermatological treatment for precancerous skin lesions, and while both treatments are FDA-approved, their combined use has not been previously evaluated. The study aims to determine if Imipramine can enhance the effectiveness of PDT and reduce associated pain. Participants will be individuals who have been recommended PDT by their dermatologist due to multiple actinic keratosis lesions.

Why it matters

Potential benefit: If successful, this approach could significantly reduce pain during PDT and improve treatment outcomes for patients with actinic keratosis.

How similar studies have gone: While PDT is a well-established treatment, the combination with Imipramine is novel and has not been previously tested in clinical settings.
