    Outcome Measures

    Primary Outcome Measures

    1. Proportion of Patients Achieving a Validated Investigator Global Assessment Scale for Atopic Dermatitis Score of 0 or 1 and a Decrease of at Least 2 Points in vIGA-ADTM in Treated Population Compared to Placebo Population From Baseline at Week 16. [16 Weeks]

      Proportion of patients achieving a Validated Investigator Global Assessment Scale for Atopic Dermatitis (vIGA-ADTM) score of 0 (clear) or 1 (almost clear) and a decrease of at least 2 points in vIGA-ADTM in treated population compared to placebo population from Baseline at Week 16 using GLMM.

    2. Proportion of Patients Achieving EASI-75 in Treated Population Compared to Placebo Population at Week 16. [16 Weeks]

      Proportion of patients achieving EASI-75 (≥75% improvement from Baseline) in treated population compared to placebo population at Week 16 using GLMM.

    Secondary Outcome Measures

    1. Proportion of Patients Achieving a vIGA-ADTM Score of 0 or 1 and a Decrease of at Least 2 Points in vIGA-ADTM in Treated Population Compared to Placebo Population From Baseline to Week 4, 8, 12, 18 and 20. [Baseline, Week 4, Week 8, Week 12, Week 18 and Week 20.]

      Proportion of patients achieving a vIGA-ADTM score of 0 (clear) or 1 (almost clear) and a decrease of at least 2 points in vIGA-ADTM in treated population compared to placebo population from Baseline to Week 4, 8, 12, 18 and 20 and the change in proportion of patients from Week 16 to Week 18 and 20.

    2. Proportion of Patients Achieving EASI-75 in Treated Population Compared to Placebo Population at Weeks 4, 8, 12, 18 and 20. [Baseline, Week 4, Week 8, Week 12, Week 18 and Week 20.]

      Proportion of patients achieving EASI-75 (≥75% improvement from Baseline) in treated population compared to placebo population at Weeks 4, 8, 12, 18 and 20.

    3. Change From Baseline in Validated Investigator Global Assessment Scale for Atopic Dermatitis (vIGA-ADTM) Score in Treated Population Compared to Placebo Population to Weeks 4, 8, 12, 16, 18 and 20, and From Week 16 to Week 18 and 20. [20 Weeks]

      The Validated Global Investigator Assessment scale for Atopic DermatitisTM (vIGA-AD) scale awards a score of 0-4 based on a 5-point severity scale from clear to severe disease (0 = clear, 1 = almost clear, 2 = mild disease, 3 = moderate disease, 4 = severe disease). The scale uses clinical characteristics of erythema, infiltration, papulation and oozing/crusting as scoring guidelines for the overall severity assessment. A decrease in vIGA indicates a positive outcome for the participant.

    4. Change From Baseline in EASI in Treated Population Compared to Placebo Population to Weeks 4, 8, 12, 16, 18 and 20, and From Week 16 to Week 18 and 20. [Week 20]

      Change from Baseline in Eczema Area and Severity Index (EASI) in treated population compared to placebo population to Weeks 4, 8, 12, 16, 18 and 20, and from Week 16 to Week 18 and 20. EASI quantifies the severity of a patient's atopic dermatitis (AD) based on both lesion severity and the percent of body surface area (BSA) affected. The EASI is a composite score ranging from 0-72 that takes into account the degree of erythema, induration/papulation, excoriation, and lichenification (each scored from 0 to 3 separately, half points are permitted) for each of four body regions, with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. The severity of each sign is assessed using a 4-point scale (half points are permitted): 0 = none 1 = mild 2 = moderate 3 = severe A decrease in EASI indicates a positive outcome for the participant.

    5. Proportion of Patients Achieving a Decrease of at Least 4 Points in Worst Itch Numeric Rating Scale (NRS) in Treated Population Compared to Placebo Population From Baseline to Week 4, 8, 12, 16, 18 and 20. [Week 20]

      Proportion of patients achieving a decrease of at least 4 points in worst itch numeric rating scale in treated population compared to placebo population from Baseline to Week 4, 8, 12, 16, 18 and 20.

    6. Proportion of Patients Achieving a Decrease of at Least 3 Points in Worst Itch NRS in Treated Population Compared to Placebo Population From Baseline to Week 4, 8, 12, 16, 18 and 20. [Week 20]

      Proportion of patients achieving a decrease of at least 3 points in worst itch NRS in treated population compared to placebo population from Baseline to Week 4, 8, 12, 16, 18 and 20.

    7. Change From Baseline in Worst Itch NRS in Treated Population Compared to Placebo Population to Week 4, 8, 12, 16 and 18. [Week 20]

      Change from Baseline in worst itch Numeric Rating Scale (NRS) in treated population compared to placebo population to Week 4, 8, 12, 16 and 18. Severity of pruritus related to atopic dermatitis (AD) was self-assessed by patients daily using the NRS. Patients were asked to estimate the intensity of pruritus at its worst over the previous 24 hours. The Pruritus NRS is a single-question assessment tool that was used to assess the patient's worst itch as a result of AD in the previous 24 hours. Patients will score their pruritus due to AD on a scale of 0 - 10, with 0 indicating no itch and 10 indicating the worst itch imaginable. Patients will complete the rating scale daily starting at screening through to the last study visit. A decrease in worst itch NRS indicates a positive outcome for the participant.

    8. Proportion of Patients Achieving EASI-50 in Treated Population Compared to Placebo Population at Week 4, 8, 12, 16, 18 and 20. [Week 20]

      Proportion of patients achieving EASI-50 (≥50% improvement from Baseline) in treated population compared to placebo population at Week 4, 8, 12, 16, 18 and 20.

    9. Change From Baseline in the Body Surface Area Affected by AD in Treated Population Compared to Placebo Population to Weeks 4, 8, 12, 16, 18 and 20, and From Week 16 to Week 18 and 20. [Week 20]

      Change from Baseline in the Body Surface Area (BSA) affected by AD in treated population compared to placebo population to Weeks 4, 8, 12, 16, 18 and 20, and from Week 16 to Week 18 and 20.

    10. Change From Baseline in the SCORing Atopic Dermatitis (SCORAD) Score in Treated Population Compared to Placebo Population to Weeks 4, 8, 12, 16, 18 and 20, and From Week 16 to Week 18 and 20. [20 Weeks]

      The SCORAD grading system was developed by the European Task Force on Atopic Dermatitis and has been a standard tool to assess atopic dermatitis (AD) severity in clinical studies. Six items (erythema, edema/papulation, oozing/crusts, excoriation, lichenification, and dryness) will be selected to evaluate the AD severity. The intensity of each item is graded using a 4-point scale: 0 = No symptoms 1 = Mild 2 = Moderate 3 = Severe The overall body surface area (BSA) affected by AD will be evaluated (from 0 to 100%) and included in the SCORAD scores. Loss of sleep and pruritus will be evaluated by patients on a visual analog scale (0-10). The SCORAD formula is A/5 + 7B/2 + C. In this formula A is defined as the extent (0-100), B is defined as the intensity (0-18) and C is defined as the subjective symptoms (0-20). The sum of these measures represents the SCORAD which can vary from 0 to 103. A decrease in SCORAD indicates a positive outcome for the participant.

    Description The Validated Global Investigator Assessment scale for Atopic DermatitisTM (vIGA-AD) scale awards a score of 0-4 based on a 5-point severity scale from clear to severe disease (0 = clear, 1 = almost clear, 2 = mild disease, 3 = moderate disease, 4 = severe disease). The scale uses clinical characteristics of erythema, infiltration, papulation and oozing/crusting as scoring guidelines for the overall severity assessment. A decrease in vIGA indicates a positive outcome for the participant.

EASI quantifies the severity of a patient's atopic dermatitis (AD) based on both lesion severity and the percent of body surface area (BSA) affected. The EASI is a composite score ranging from 0-72 that takes into account the degree of erythema, induration/papulation, excoriation, and lichenification (each scored from 0 to 3 separately, half points are permitted) for each of four body regions, with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. The severity of each sign is assessed using a 4-point scale (half points are permitted): 0 = none 1 = mild 2 = moderate 3 = severe A decrease in EASI indicates a positive outcome for the participant.

    Description Change from Baseline in worst itch Numeric Rating Scale (NRS) in treated population compared to placebo population to Week 4, 8, 12, 16 and 18. Severity of pruritus related to atopic dermatitis (AD) was self-assessed by patients daily using the NRS. Patients were asked to estimate the intensity of pruritus at its worst over the previous 24 hours. The Pruritus NRS is a single-question assessment tool that was used to assess the patient's worst itch as a result of AD in the previous 24 hours. Patients will score their pruritus due to AD on a scale of 0 - 10, with 0 indicating no itch and 10 indicating the worst itch imaginable. Patients will complete the rating scale daily starting at screening through to the last study visit. A decrease in worst itch NRS indicates a positive outcome for the participant.

    Description The SCORAD grading system was developed by the European Task Force on Atopic Dermatitis and has been a standard tool to assess atopic dermatitis (AD) severity in clinical studies. Six items (erythema, edema/papulation, oozing/crusts, excoriation, lichenification, and dryness) will be selected to evaluate the AD severity. The intensity of each item is graded using a 4-point scale: 0 = No symptoms 1 = Mild 2 = Moderate 3 = Severe The overall body surface area (BSA) affected by AD will be evaluated (from 0 to 100%) and included in the SCORAD scores. Loss of sleep and pruritus will be evaluated by patients on a visual analog scale (0-10). The SCORAD formula is A/5 + 7B/2 + C. In this formula A is defined as the extent (0-100), B is defined as the intensity (0-18) and C is defined as the subjective symptoms (0-20). The sum of these measures represents the SCORAD which can vary from 0 to 103. A decrease in SCORAD indicates a positive outcome for the participant.
