Apremilast 30 mg Twice Daily (BID) Combined With Dupilumab

The purpose of this study is to determine if apremilast as a combined treatment for atopic dermatitis will provide increased efficacy outcomes in subjects who are currently using the FDA approved therapy of dupilumab but have responded only partially or inadequately to this therapy. Our hypothesis is that adding apremilast will allow patients to go from an inadequate response to dupilumab to an adequate response defined as an Investigator Global Assessment (IGA) of 0 (clear) or 1 (almost clear).
