Percentage of Subjects Who Achieved Eczema Area and Severity Index (EASI)-75 at Week 12 | ||||||||||||
End point description |
Percentage of subjects who achieved EASI-75 at Week 12 were reported. EASI-75 response was defined as at least 75 percent (%) improvement from baseline in EASI total score. The EASI score was used to measure the severity and extent of atopic dermatitis (AD) and measures erythema, infiltration/papulation, excoriation and lichenification on 4 anatomic regions of the body: head or neck, trunk, upper and lower limbs. The total EASI score ranged from 0 (minimum) to 72 (maximum) points, with the higher scores indicated the worse severity of AD. Full analysis set (FAS) included all randomised subjects who had received at least 1 dose of study intervention and provided both baseline and at least 1 postbaseline data.

Percentage of Subjects With Improvement (Reduction From Baseline) in Eczema Related Itch Numeric Rating Scale (NRS) Score of >=4 at Week 12 Among Subjects With a Baseline Itch Value >=4 | ||||||||||||
End point description |
Percentage of subjects with improvement (reduction from baseline) in eczema-related itch NRS score of >=4 at Week 12 among subjects with a baseline itch value >=4 was reported. The eczema skin pain and Itch NRS is a 3-item patient-reported outcome that subjects used to rate the severity of their eczema-related skin pain and eczema related itch daily. Subjects were asked the following questions: please rate the severity of eczema-related itch at its worst in the past 24 hours. Each item was on a 0 to 10 NRS ranging from 0 "none" to 10 "worst possible”. Higher score indicated more severity. FAS included all randomised subjects who had received at least 1 dose of study intervention and provided both baseline and at least 1 postbaseline data.

End point description |
Percentage of subjects who achieved vIGA-AD of 0 or 1 and a reduction from baseline of >=2 points at Week 12 were reported. It was an assessment instrument used in clinical studies to rate the severity of AD, based on a 5-point scale ranged from 0 to 4, where 0=Clear: No inflammatory signs of AD; 1=almost clear: Barely perceptible erythema, induration/papulation and/or lichenification. No oozing or crusting; 2=mild: Slight but definite erythema, induration/papulation and/or minimal lichenification. No oozing or crusting; 3=moderate: Clearly perceptible erythema, induration/ papulation and/or lichenification, oozing or crusting may present, 4=severe: Marked erythema, induration/papulation and/or lichenification; Oozing or crusting may be present. Higher score indicated more severity of AD. FAS included all randomised subjects who had received at least 1 dose of study intervention and provide both baseline and at least 1 postbaseline data.

Percentage of Subjects With Treatment-emergent Serious Adverse Events (TESAEs) | ||||||||||||
End point description |
An AE was any untoward medical occurrence in a clinical study subject administered a pharmaceutical (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. Serious adverse events (SAE) is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalisation or prolongation of existing hospitalisation, is life-threatening experience, is a congenital anomaly/birth defect and may jeopardize subject and/or may require medical or surgical intervention to prevent one of the outcomes listed above. TESAE were SAEs with onset after or on the date of the first dose of the study intervention or that were a consequence of a pre-existing condition that had worsened since baseline. The safety analysis set included all randomised subjects who had received at least 1 dose of study intervention.

An adverse event (AE) was any untoward medical occurrence in a clinical study subject administered a pharmaceutical (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product. TEAE were AEs with onset after or on the date of the first dose of the study intervention or that were a consequence of a pre-existing condition that had worsened since baseline.
