Design outcomes

Primary

MeasureTime frameDescription
Proportion of Participants with Eczema Area and Severity Index (EASI) 75 Response at Week 12Week 12EASI-75 response is defined as at least 75 percent (%) improvement from baseline in EASI total score. EASI is a validated measure used to assess the severity and extent of AD with scores ranging from 0 to 72. Four AD disease characteristics (erythema, thickness \[induration, papulation, edema\], scratching \[excoriation\], and lichenification) will each be assessed for severity by the investigator or designee on a scale of "0" (absent) through "3" (severe). In addition, the area of AD involvement will be assessed as a percentage by body area of head, trunk, upper limbs, and lower limbs, and converted to a score of 0 to 6. In each body region, the area is expressed as 0, 1 (1% to 9%), 2 (10% to 29%), 3 (30% to 49%), 4 (50% to 69%), 5 (70% to 89%), or 6 (90% to 100%). Here higher score indicates higher severity of AD.

Secondary

MeasureTime frameDescription
Proportion of Participants with EASI 90 Response at Week 12Week 12EASI-90 response is defined as at least 90% improvement from baseline in EASI total score. EASI is a validated measure used to assess the severity and extent of AD with scores ranging from 0 to 72. Four AD disease characteristics (erythema, thickness \[induration, papulation, edema\], scratching \[excoriation\], and lichenification) will each be assessed for severity by the investigator or designee on a scale of "0" (absent) through "3" (severe). In addition, the area of AD involvement will be assessed as a percentage by body area of head, trunk, upper limbs, and lower limbs, and converted to a score of 0 to 6. In each body region, the area is expressed as 0, 1 (1% to 9%), 2 (10% to 29%), 3 (30% to 49%), 4 (50% to 69%), 5 (70% to 89%), or 6 (90% to 100%). Here higher score indicates higher severity of AD.
Proportion of Participants with EASI 100 Response at Week 12Week 12EASI-100 response is defined as at least 100% improvement from baseline in EASI total score. EASI is a validated measure used to assess the severity and extent of AD with scores ranging from 0 to 72. Four AD disease characteristics (erythema, thickness \[induration, papulation, edema\], scratching \[excoriation\], and lichenification) will each be assessed for severity by the investigator or designee on a scale of "0" (absent) through "3" (severe). In addition, the area of AD involvement will be assessed as a percentage by body area of head, trunk, upper limbs, and lower limbs, and converted to a score of 0 to 6. In each body region, the area is expressed as 0, 1 (1% to 9%), 2 (10% to 29%), 3 (30% to 49%), 4 (50% to 69%), 5 (70% to 89%), or 6 (90% to 100%). Here higher score indicates higher severity of AD.
Percent Change from Baseline in EASI Total Score at Week 12Baseline, Week 12Percent change from baseline in EASI total score will be reported. EASI is a validated measure used to assess the severity and extent of AD with scores ranging from 0 to 72. Four AD disease characteristics (erythema, thickness \[induration, papulation, edema\], scratching \[excoriation\], and lichenification) will each be assessed for severity by the investigator or designee on a scale of "0" (absent) through "3" (severe). In addition, the area of AD involvement will be assessed as a percentage by body area of head, trunk, upper limbs, and lower limbs, and converted to a score of 0 to 6. In each body region, the area is expressed as 0, 1 (1% to 9%), 2 (10% to 29%), 3 (30% to 49%), 4 (50% to 69%), 5 (70% to 89%), or 6 (90% to 100%). Here higher score indicates higher severity of AD.
Proportion of Participants with Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) Score of 0 or 1 and a Reduction of >= 2 Points from Baseline, at Week 12Week 12Proportion of participants with vIGA-AD score of 0 or 1 and a reduction of \>=2 points from baseline at Week 12 will be reported. vIGA-AD is an assessment instrument used in clinical studies to rate the severity of AD, based on a 5-point scale ranging from 0 (clear) to 4 (severe). The IGA score is selected using the morphological descriptors that best describe the overall appearance of the AD lesions at a given time point. Higher scores are indicative of a more severe AD.
Proportion of Participants with vIGA-AD Score of 0 and a Reduction of >= 2 points from Baseline, at Week 12Week 12Proportion of participants with vIGA-AD score of 0 and a reduction of \>=2 points from baseline at Week 12 will be reported. vIGA-AD is an assessment instrument used in clinical studies to rate the severity of AD, based on a 5-point scale ranging from 0 (clear) to 4 (severe). The IGA score is selected using the morphological descriptors that best describe the overall appearance of the AD lesions at a given time point. Higher scores are indicative of a more severe AD.
Proportion of Participants with >= 4-Point Improvement in Peak Pruritus Numeric(al) Rating Scale (PP-NRS) from Baseline, at Week 12Week 12Proportion of participants with \>=4-point improvement from baseline in PP-NRS scale at Week 12 will be reported. PP-NRS is a single item asking participants to assess their worst itch over the past 24 hours. There are 11 response categories, ranging from 0 (no itch) to 10 (worst itch imaginable). Higher score indicates greater severity.
Percent Change from Baseline in PP-NRS Score at Week 12Baseline, Week 12Percent change from baseline in PP-NRS score will be reported. PP-NRS is a single item asking participants to assess their worst itch over the past 24 hours. There are 11 response categories, ranging from 0 (no itch) to 10 (worst itch imaginable). Higher score indicates greater severity.
Percent Change from Baseline in Score of Item 2 of Atopic Dermatitis Sleep Scale (AD Sleep Scale) at Week 12Baseline, Week 12Percent change from baseline in the score of Item 2 of AD Sleep Scale at Week 12 will be reported. The AD Sleep Scale is a validated 3-item participant-reported outcome (PRO) instrument to capture self-reported impact of itch on sleep disturbance each day, including difficulty falling asleep, number of night-time awakenings, and difficulty falling back asleep after waking during the previous night. For Item 2, participants select the number of times they woke up each night, ranging from 0 to 29 times. Higher score indicates more sleep disturbance.
Proportion of Participants with >= 4 Point Improvement in Skin Pain Numeric Rating Scale (Skin Pain NRS) from Baseline, at Week 12Week 12Proportion of participants with \>= 4 point improvement from baseline in skin pain NRS at Week 12 will be reported. Skin Pain NRS is a single item asking participants to assess their worst skin pain over the past 24 hours. There are 11 response categories, ranging from 0 (no pain) to 10 (worst pain imaginable). Higher score indicates more pain.
Percent Change from Baseline in Skin Pain NRS at Week 12Baseline, Week 12Percent change from baseline in Skin Pain NRS at Week 12 will be reported. Skin Pain NRS is a single item asking participants to assess their worst skin pain over the past 24 hours. There are 11 response categories, ranging from 0 (no pain) to 10 (worst pain imaginable). Higher score indicates more pain.
Number of Participants with Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)Up to approximately Week 12An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the intervention. TEAEs are AEs with onset during the intervention phase or that are a consequence of a preexisting condition that has worsened since baseline. An SAE is any untoward medical occurrence that at any dose: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is a suspected transmission of any infectious agent via a medicinal product and is medically important.
