Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate whether a dermal formulation of roflumilast is superior compared with vehicle on the reduction of psoriatic infiltrate thickness during 21 days of treatment in subjects with chronic plaque psoriasis. To evaluate whether a dermal formulation of BYK321084 (at 2 concentrations) is superior compared with vehicle (to roflumilast) on the reduction of psoriatic infiltrate thickness during 21 days of treatment in subjects with chronic plaque psoriasis.;Secondary Objective: To evaluate the safety and tolerability of a dermal formulation of roflumilast. To evaluate the safety and tolerability of a dermal formulation of BYK321084 (at 2 concentrations). To compare the efficacy (thickness of psoriatic skin infiltrate and clinical severity) of dermal roflumilast with active comparators. To compare the efficacy (thickness of psoriatic skin infiltrate and clinical severity) of dermal BYK321084 with active comparators.;Primary end point(s): The primary endpoint for this study is the change from Baseline in thickness of the psoriatic skin infiltrate on Day 22 (assessed using 20 MHz sonographic measurement).;Timepoint(s) of evaluation of this end point: Day 22

Secondary

MeasureTime frame
Secondary end point(s): Change from Baseline in thickness of the psoriatic skin infiltrate on Days 8 and 15 (assessed using 20 MHz sonographic measurement). AUC of the baseline-corrected thickness of the psoriatic skin infiltrate on Days 1, 8, 15 and 22 (assessed using 20 MHz sonographic measurement). Change in clinical severity of the psoriatic lesions within each test field area on Days 8, 15 and 22 compared with Baseline and with untreated plaque(s) beneath the hydrocolloid dressing.;Timepoint(s) of evaluation of this end point: Days 1, 8, 15, 22
