Primary outcomes

  1. Proportion of AD patients with a Conner's CPT-3 d' T-score ≥ 60

    Time frame: Day 1

    Part A

    Conners' Continuous Performance Test-3 (CPT-3): an objective test of attention and impulsivity that has been validated in individuals aged 8 years and older. The primary efficacy outcome measure (d' T-score) is a measure of "signal detectability" with respect to inattentiveness, that is, the respondent's ability to differentiate non-targets (ie, the letter X) from targets (ie, all other letters), and is calculated as: d' = z-score ("False Alarm") - z-score ("Hit"). "T scores" refer to a distribution of the d' statistic such that the mean is 50 and the standard deviation (SD) is 10. Lower d' T-score values indicate worse performance.

  2. Mean change from baseline in Conner's CPT-3 d' T-score

    Time frame: At week 16

    Part B

    Conner's CPT-3 d' T-scoring as stated above.

Secondary outcomes

  1. Correlation of values for Conners' Continuous Performance Test 3rd Edition (CPT-3) scores (d' T-score, Commission Errors, Omission Errors, and Reaction Time) with AD disease severity based on Eczema Area and Severity Index (EASI)

    Time frame: Day 1

    Part A

    Conner's CPT-3 d' T-scoring as stated above.

    EASI is a validated measure used in clinical practice and clinical trials to assess the severity and extent of AD. Four AD disease characteristics (erythema, thickness [induration, apulation, 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.

  2. Correlation of values for Conners' CPT-3 scores with AD disease severity based on Body Surface Area (BSA)

    Time frame: Day 1

    Part A

    Conner's CPT-3 d' T-scoring as stated above.

    BSA affected by AD is assessed for each section of the body using the rule of nines (the possible highest score for each region is: head and neck [9%], anterior trunk [18%], back [18%], upper limbs [18%], lower limbs [36%], and genitals [1%]) and will be reported as a percentage of all major body sections combined.

  3. Correlation of values for Conners' CPT-3 scores with AD disease severity based on Peak Pruritus Numeric Rating Scale (NRS)

    Time frame: Day 1

    Part A

    Conner's CPT-3 d' T-scoring as stated above.

    Peak Pruritus NRS is a simple assessment tool that patients will use to report the average intensity of their pruritus (itch), both maximum and average intensity, during a 24-hour recall period; maximum itch intensity on a scale of 0 - 10 (0 = no itch; 10 = worst itch imaginable).

  4. Correlation of values for Conners' CPT-3 scores with AD disease severity based on Skin Pain Numeric Rating Scale (SP-NRS)

    Time frame: Day 1

    Part A

    Conner's CPT-3 d' T-scoring as stated above.

    SP-NRS is a validated, self-administered PRO measuring the skin pain severity at its worst with a recall period of 24 hours pain severity in adults and adolescents. This single-item questionnaire uses an 11-point scale, which ranges from "0-No pain" to "10-Worst pain possible." Skin pain severity based on SP-NRS can be categorized as: clear (0), mild (1-3), moderate (5-6), severe (7-9), and very severe (10).

  5. Correlation of values for Conners' CPT-3 scores with AD disease severity based on Patient-Reported Outcomes Measurement Information System Pediatric Sleep Disturbance Questionnaire (PROMIS Pediatric Sleep Disturbance)

    Time frame: Day 1

    Part A

    Conner's CPT-3 d' T-scoring as stated above.

    PROMIS sleep disturbance questionnaire is used to measure self-reported perceptions of sleep quality, sleep depth, and restoration. This includes perceived difficulties getting to sleep and staying asleep, as well as sleep satisfaction. Parent-reported sleep.

  6. Correlation of values for Conners' CPT-3 scores with AD disease severity based on Children's Dermatology Life Quality Index (CDLQI)

    Time frame: Day 1

    Part A

    Conner's CPT-3 d' T-scoring as stated above.

    CDLQI is a validated questionnaire designed to measure the impact of skin disease on the quality of life (QoL) in children over a recall period of the past week. 9 of the 10 questions are scored by (0) Not answered/not at all, (1) only a little, (2) quite a lot to (3) very much. Question 7 has a possible response of (3) prevented school. The sum of the score of each question has a maximum of 30 and a minimum of 0. The higher the score the greater the impact on QoL. CDLQI can be a percentage of the maximum possible score of 30.

  7. Correlation of values for Conners' CPT-3 scores with AD disease severity based on Hospital Anxiety and Depression Scale (HADS)

    Time frame: Day 1

    Part A

    Conner's CPT-3 d' T-scoring as stated above.

    HADS is an instrument for screening anxiety and depression in non-psychiatric populations; repeated administration also provides information about changes in a patient's emotional state. HADS consists of 14 items, 7 each for anxiety and depression symptoms; possible scores range from 0 to 21 for each subscale. The following cut-off scores are recommended for both subscales: 7 to 8 for possible presence, 10 to 11 for probable presence, and 14 to 15 for severe anxiety or depression.

  8. Correlation of values for Conners' CPT-3 scores with AD disease severity based on Investigator's Global Assessment (IGA)

    Time frame: Day 1

    Part A

    Conner's CPT-3 d' T-scoring as stated above.

    IGA is an instrument used for rapid and easy assessment of atopic dermatitis disease lesional severity globally based on a 5-point scale with range from 0-4, (0 = Clear, 1 = Almost clear, 2 = Mild disease, 3 = Moderate disease and 4 = Severe disease).

  9. Correlation of values for Adult/Adolescent Sensory Profile (AASP) Sensory Sensitivity Score with AD disease severity based on EASI

    Time frame: Day 1

    Part A

    AASP is a 60-item self-report questionnaire measuring sensory responsiveness patterns in six different sensory modalities, including taste/smell, movement, visual, touch, activity and auditory processing. Patients complete the AASP by responding to each item with a five-point Likert scale (1 = almost never, 2 = seldom, 3 =occasionally, 4 = frequently, or 5 = always). Higher scores in each quadrant represented stronger preference to adopt certain types of sensory responsiveness patterns. The quadrant score can be categorized into one of the 5 categories, indicating how a particular patient's score compares to people in the same age group (adolescents of age 11-17 years) without disabilities: much less than most people, less than most people, similar to most people, more than most people, much more than most people.
