NCT05688904

Brief Summary

The purpose of this study is testing the use of topical Imipramine in combination with topical photodynamic therapy's (PDT) effect on pain following treatment. PDT is a commonly used treatment in dermatology for patients who have many pre-cancers (actinic keratosis-AKs) on their skin. These are both FDA-approved treatments, but this study is evaluating their use in combination, which has not been evaluated in the past. The investigators have been doing studies using animals that suggest that imipramine might make the PDT less painful and might help it work better. In order to participate, the subject and their dermatologist have decided that they would benefit from PDT to treat their skin due to many AK precancerous lesions. Please note that neither PDT nor imipramine are experimental treatments, but treating their skin with imipramine before PDT is a new approach.

Outcome Measures

Primary Outcomes (1)

  • Number of precancerous actinic keratosis present from baseline.

    Principal investigator assesses this from AK lesion count mapping at baseline and in 6 months.

    6 months post PDT treatment

Secondary Outcomes (8)

  • Change in pain level due to photodynamic therapy (PDT) from baseline.

    Immediately post PDT treatment

  • Change in pain level due to photodynamic therapy (PDT) from baseline.

    10 minutes post PDT treatment

  • Change in pain level due to photodynamic therapy (PDT) from baseline.

    30 minutes post PDT treatment

  • Change in pain level due to photodynamic therapy (PDT) from baseline.

    6 months post PDT treatment

  • Change in itch level due to photodynamic therapy (PDT) from baseline.

    Immediately post PDT treatment

  • +3 more secondary outcomes
