The small device, about the size of a grain of rice, has up to 20 tiny reservoirs that hold medications that are approved by the Food and Drug Administration (FDA) for atopic dermatitis and psoriasis. Very small amounts of these medications will be released into the skin (at levels in your body much lower than are typically used). In this study, the device will be tested to see if it's safe and works well for predicting how the skin will react to standard treatments. We will also look at how these reactions are connected to genetic information and overall treatment results.

The small device, about the size of a grain of rice, has up to 20 tiny reservoirs that hold medications that are approved by the Food and Drug Administration (FDA) for atopic dermatitis and psoriasis. In this study, the device will be tested to see if it's safe and works well for predicting how the skin will react to standard treatments. The microdevice will contain a subset of the following: Triamcinolone, 5-fluorouracil, Calcipotriene, Tapinarof, Crisaborole, Tacrolimus, Adalimumab, Etanercept, Certolizumab, Infliximab, Secukinumab, Ixekizumab, Apremilast, Risankizumab, Ustekinumab, Hydroxychloroquine, Methotrexate, Mycophenolate, Azathioprine, Chloroquine, Cyclosporine, Tofacitinib, Deucravacitinib, Dupilumab, Tralokinumab, Guselkumab, Tildrakizumab, Baractinib, Abrocitinib, Upadacitinib, Lebrikizumab, Nemolizumab, Ruxolitinib, Bimekizumab, Roflumilast.

The safety of microdevice placement and removal will be based on assessment of adverse events.

The feasibility of microdevice analysis based on the ability to place and retrieve the device with sufficient tissue, of sufficient quality, for downstream histopathology/molecular analysis and interpretation of at least 80% of the device reservoirs.

Feasibility of utilizing quantitative histopathologic assessment and/or transcriptional profiling to determine whether there is local change in lesional rash-affected skin with clinically relevant skin inflammation treating agents.
