简要总结
Principal aim of this study is to assess whether a combination of topical dapsone and clobetasol as a topical steroid is superior to clobetasol alone as treatment of prurigo nodularis or lichen simplex chronicus in a side to side comparison. The study is primarily exploratory and essentially meant to inform the sponsor whether further development of a combination treatment formulation is warranted
