What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Physician's Global Assessment of Disease Severity (PGA) Score of 0 (Clear) or 1 (Almost Clear) at Day 29, With at Least a 2-point Reduction From Baseline	The efficacy of LEO 90100 compared with Daivobet® ointment on severity and extent of stable plaque psoriasis was evaluated. The PGA is an instrument used in clinical trials to rate the severity of psoriasis. It is a 5-point scale measurement ranging from 0 to 4, where 0- clear, 1- almost clear, 2- mild, 3- moderate and 4- severe; based on degree of plaque thickening, scaling and erythema. Higher score showed worse outcome.	On Day 29

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Decrease in Modified Psoriasis Area and Severity Index of at Least 75% (mPASI-75) From Baseline to Day 29	The efficacy of LEO 90100 compared with Daivobet® ointment on severity and extent of stable plaque psoriasis was evaluated. The extent of psoriatic involvement will be recorded for each of the areas (trunk [including the neck] and the limbs [such as arms and legs]; excluding any involvement on face, scalp, genitals and skin folds) using the following scale: 0=no involvement, 1=< 10%, 2=10%-29%, 3=30%-49%, 4=50%-69%, 5=70%-89%, 6=90%-100%. The severity of the psoriatic lesions in each of the areas will be recorded for each of the clinical signs of redness, thickness and scaliness. Each clinical sign is scored on a scale of 0-4, reflecting the average severity of all psoriatic lesions on the given body region. Higher score indicates more severity. The overall mPASI can range from 0 to 64.8.	From Baseline to Day 29
Percentage of Participants With Decrease in mPASI of at Least 90% (mPASI-90) From Baseline to Day 29	The efficacy of LEO 90100 compared with Daivobet® ointment on severity and extent of stable plaque psoriasis was evaluated. The extent of psoriatic involvement will be recorded for each of the areas (trunk [including the neck] and the limbs [such as arms and legs]; excluding any involvement on face, scalp, genitals and skin folds) using the following scale: 0=no involvement, 1=< 10%, 2=10%-29%, 3=30%-49%, 4=50%-69%, 5=70%-89%, 6=90%-100%. The severity of the psoriatic lesions in each of the areas will be recorded for each of the clinical signs of redness, thickness and scaliness. Each clinical sign is scored on a scale of 0-4, reflecting the average severity of all psoriatic lesions on the given body region. Higher score indicates more severity. The overall mPASI can range from 0 to 64.8.	From Baseline to Day 29
Number of Participants With Treatment-emergent Adverse Events (TEAEs)	The safety of LEO 90100 compared with Daivobet® ointment treating stable plaque psoriasis was evaluated. Only treatment emergent adverse events (TEAEs) have been reported for this outcome measure. An event was considered treatment-emergent if it started after the first investigational medicinal product (IMP) administration or if it started before the first IMP administration and worsened in severity after the first IMP administration.	From Baseline to Day 43
