What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants Achieving at Least a 75% Reduction in Eczema Area and Severity Index Score (EASI 75) From Baseline at Week 16

    EASI is a tool used to measure the extent (area) and severity of atopic eczema based on assessments of the head/neck, trunk, upper limbs and lower limbs. For each region the area score is recorded as the percentage of skin affected by eczema. For each region, the severity score is calculated as the sum of the intensity scores (scored as none [0], mild [1], moderate [2], or severe [3]) for redness (erythema, inflammation), thickness (induration, papulation, swelling - acute eczema), scratching (excoriation), and lichenification (lined skin, prurigo nodules - chronic eczema).

    The total EASI score for each region is calculated by multiplying the severity score by the area score, with adjustment for the proportion of the body region to the whole body. The final EASI score is the sum of the 4 region scores and ranges from 0 to 72 where higher scores represent worse disease.

    Measured: At Week 16

  2. Percentage of Participants Who Reported Adverse Events

    An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent adverse events/treatment-emergent serious adverse events (TEAEs/TESAEs) are defined as any event that began or worsened in severity on or after the first dose of study drug.

    Measured: Up to Week 52

Secondary outcomes (13)
  1. Percentage of Participants Achieving an Improvement (Reduction) of ≥ 4 Points From Baseline in Worst Pruritus Numerical Rating Scale (WP-NRS)

    Participants were asked to rate itch (pruritus) intensity at its worst during the past 24 hours on a daily basis using an 11-point scale from 0 (no itch) to 10 (worst imaginable itch). Pruritus NRS was analyzed based on weekly rolling averages of daily scores.

    Measured: At Week 4

  2. Percentage of Participants Achieving an EASI 50 Response

    EASI is a tool used to measure the extent (area) and severity of atopic eczema based on assessments of the head/neck, trunk, upper limbs and lower limbs. For each region the area score is recorded as the percentage of skin affected by eczema. For each region, the severity score is calculated as the sum of the intensity scores (scored as none [0], mild [1], moderate [2], or severe [3]) for redness (erythema, inflammation), thickness (induration, papulation, swelling - acute eczema), scratching (excoriation), and lichenification (lined skin, prurigo nodules - chronic eczema).

    The total EASI score for each region is calculated by multiplying the severity score by the area score, with adjustment for the proportion of the body region to the whole body. The final EASI score is the sum of the 4 region scores and ranges from 0 to 72 where higher scores represent worse disease.

    An EASI 50 response is defined as at least a 50% reduction (improvement) from Baseline in EASI score.

    Measured: At Week 16

  3. Percentage of Participants Achieving an EASI 90 Response

    EASI is a tool used to measure the extent (area) and severity of atopic eczema based on assessments of the head/neck, trunk, upper limbs and lower limbs. For each region the area score is recorded as the percentage of skin affected by eczema. For each region, the severity score is calculated as the sum of the intensity scores (scored as none [0], mild [1], moderate [2], or severe [3]) for redness (erythema, inflammation), thickness (induration, papulation, swelling - acute eczema), scratching (excoriation), and lichenification (lined skin, prurigo nodules - chronic eczema).

    The total EASI score for each region is calculated by multiplying the severity score by the area score, with adjustment for the proportion of the body region to the whole body. The final EASI score is the sum of the 4 region scores and ranges from 0 to 72 where higher scores represent worse disease.

    An EASI 90 response is defined as at least a 90% reduction (improvement) from Baseline in EASI score.

    Measured: At Week 16

  4. Percentage of Participants Achieving an EASI 100 Response

    EASI is a tool used to measure the extent (area) and severity of atopic eczema based on assessments of the head/neck, trunk, upper limbs and lower limbs. For each region the area score is recorded as the percentage of skin affected by eczema. For each region, the severity score is calculated as the sum of the intensity scores (scored as none [0], mild [1], moderate [2], or severe [3]) for redness (erythema, inflammation), thickness (induration, papulation, swelling - acute eczema), scratching (excoriation), and lichenification (lined skin, prurigo nodules - chronic eczema).

    The total EASI score for each region is calculated by multiplying the severity score by the area score, with adjustment for the proportion of the body region to the whole body. The final EASI score is the sum of the 4 region scores and ranges from 0 to 72 where higher scores represent worse disease.

    An EASI 100 response is defined as at least a 100% reduction (improvement) from Baseline in EASI score.

    Measured: At Week 16

  5. Percentage of Participants Achieving an Improvement (Reduction) of ≥ 4 Points From Baseline in Worst Pruritus Numerical Rating Scale (WP-NRS)

    Participants were asked to rate itch (pruritus) intensity at its worst during the past 24 hours on a daily basis using an 11-point scale from 0 (no itch) to 10 (worst imaginable itch). Pruritus NRS was analyzed based on weekly rolling averages of daily scores.

    Measured: At Week 16

  6. Absolute Change from Baseline for EASI

    EASI is a tool used to measure the extent (area) and severity of atopic eczema based on assessments of the head/neck, trunk, upper limbs and lower limbs. For each region the area score is recorded as the percentage of skin affected by eczema. For each region, the severity score is calculated as the sum of the intensity scores (scored as none [0], mild [1)] moderate [2], or severe [3]) for Redness (erythema, inflammation), Thickness (induration, papulation, swelling - acute eczema), Scratching (excoriation), and Lichenification (lined skin, prurigo nodules - chronic eczema).

    The total EASI score for each region is calculated by multiplying the severity score by the area score, with adjustment for the proportion of the body region to the whole body. The final EASI score is the sum of the 4 region scores and ranges from 0 to 72 where higher scores represent worse disease; a negative change from Baseline indicates improvement.

    Measured: At Week 16

  7. Percent Change From Baseline in EASI Score

    EASI is a tool used to measure the extent (area) and severity of atopic eczema based on assessments of the head/neck, trunk, upper limbs and lower limbs. For each region the area score is recorded as the percentage of skin affected by eczema.
