Number of Participants With Treatment Emergent Adverse Events (AEs) |
An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE was considered a treatment-emergent adverse event (TEAE) if the event started on or after the first dosing day until 28 days post last dose of study drug. AEs included both serious and non-serious AEs. |

Percent Change From Baseline in the Percentage (%) Body Surface Area (BSA) Affected at Week 2, 4, 8, 12, 16, 20 and 26 |
The extent (%) to which a body region was involved with AD was determined using handprint method. Number of handprints (size of participant's hand with fingers in a closed position) fitting in the affected area of a body region was estimated. Four body regions were evaluated: head and neck, upper limbs, trunk (including axillae and groin/genitals) and lower limbs (including buttocks). Total number of handprints were 10 for head and neck, 20 for upper limbs, 30 for trunk and 40 for lower limbs. Surface area of body region equivalent to 1 handprint: 1 handprint was equal to 10% for head and neck, 5% for upper limbs, 3.33% for trunk and 2.5% for lower limbs. Percent BSA for a body region was calculated as = total number of handprints in a body region * % surface area equivalent to 1 handprint. Overall % BSA for an individual was derived as sum of % BSA across all 4 body regions and ranged from 0 to 100%, with higher values representing greater severity of AD. |

Percent Change From Baseline in the SCORing Atopic Dermatitis (SCORAD) Total Score at Week 2, 4, 8, 12, 16, 20 and 26 |
SCORAD is a scoring index for AD which combined extent (A), severity (B) and subjective symptoms (C). For A, a rule of 9 was used to calculate BSA affected by AD as % of whole BSA for each body region- head and neck 9%; upper limbs 9% each; lower limbs 18% each; anterior trunk 18%; back 18%; genitals 1%. Score of each body region was added to determine A (range: 0-100). B: severity of each sign (erythema; edema/papulation; oozing/crusting; excoriation; skin thickening; dryness) was assessed as none (0), mild (1), moderate (2), severe (3); severity scores were added to give B (range: 0-18). C: pruritus and sleep loss, each of these 2 were scored by participant/caregiver using visual analog scale (VAS) where, 0=no itch/no sleep loss and 10=worst imaginable itch/sleep loss, higher scores=worse symptoms. Scores for itch and sleep loss were added to give 'C' (range: 0-20). SCORAD total score was calculated as: A/5+7*B/2+C; range (0-103); higher values=worse outcome. |

Change From Baseline in Total Anxiety Score Measured Using the Hospital Anxiety and Depression Scale (HADS) at Week 12,16 and 26 |
HADS was a validated 14-item questionnaire to assess states of anxiety and depression over the past week. HADS consisted of 2 subscales: HADS-Anxiety (HADS-A) scale and HADS-Depression (HADS-D) scale, each of which comprised of 7 items. Each item was rated on a 4-point scale, with scores ranging from 0 to 3, where higher scores indicated more anxiety/depression symptoms. HADS-A assessed state of generalized anxiety (anxious mood, restlessness, anxious thoughts, panic attacks). HADS-A total score was calculated as the sum of all 7 items with score ranging from 0 (no presence of anxiety) to 21 (severe feeling of anxiety); higher score indicated greater severity of anxiety. |

HADS-D assessed the state of lost interest and diminished pleasure response (lowering of hedonic tone). HADS-D: total score was calculated as the sum of all 7 items with score ranging from 0 (no presence of depression) to 21 (severe feeling of depression); higher score indicated greater severity of depression symptoms. |
