A Study to Assess Real-World Use, Safety, and Effectiveness of Oral Upadacitinib in Adult and Adolescent (>=12 Years Old) Participants With Atopic Dermatitis

Study Overview
=================
Brief Summary
-----------------
Atopic dermatitis (AD; also known as atopic eczema) is an inflammatory skin disease. The safety and effectiveness of upadacitinib for AD has been well-documented in previous studies, however, important information is missing on the use patterns and outcomes with upadacitinib in a real-world setting. Therefore, the purpose of this observational study is to help inform real-world usage patterns regarding the safety and effectiveness and duration of response of upadacitinib in adolescent and adult AD participants >=12 years old in the real-world setting. Upadacitinib is an approved drug being developed for the treatment of AD. Around 975 adolescent and adult participants who are prescribed upadacitinib for the treatment of AD in routine clinical practice will be enrolled worldwide. Participants will receive oral upadacitinib as prescribed by their physician. Data from these participants will be collected for approximately 2 years. There will be no additional burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic and will be asked to provide additional information by questionnaire at each visit.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Upadacitinib (UPA) Utilization Patterns | UPA utilization patterns will be achieved by (i) providing descriptive statistics of patient demographics and disease characteristics for patients who starting UPA 15 mg at baseline and patients who starting UPA 30 mg at baseline, respectively; (ii) calculating number and proportion of patients with different UPA and concomitant therapy changes throughout the observation period, and the rationale for any changes. | Up to Approximately 24 Months | 
| Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) 0/1 | vIGA-AD is a validated assessment instrument used in clinical studies to rate the severity of AD globally. A 5-point scale is used to measure the severity of disease at the time of the investigator's evaluation of the participant ranging from 0 - Clear (no inflammatory signs of atopic dermatitis (no erythema, no induration/papulation, no lichenification, no oozing/crusting). Post-inflammatory hyperpigmentation and/or hypopigmentation may be present.) to 4 - Severe (marked erythema (deep or bright red), marked induration/papulation, and/or marked lichenification. | Month 4 | 
| vIGA-AD 0/1 Among Participants Who Achieved vIGA-AD 0/1 at Month 4 | vIGA-AD is a validated assessment instrument used in clinical studies to rate the severity of AD globally. A 5-point scale is used to measure the severity of disease at the time of the investigator's evaluation of the participant ranging from 0 - Clear (no inflammatory signs of atopic dermatitis (no erythema, no induration/papulation, no lichenification, no oozing/crusting).

| Absolute Score and Change from Baseline in ADCT | The ADCT is a validated patient self-administered instrument designed to assess AD control status in adult and adolescent patients (12 years and older). Six AD symptoms and impacts are evaluated over the past week including overall severity of symptoms, days with intense episodes of itching, intensity of bother, problem with sleep, impact on daily activities, and impact on mood or emotions. Each item is scored 0-4. The sum of the 6 item scores form the ADCT total score (range 0-24). A higher score indicates lower AD control. A score of ≥7 indicates that the patient is not in control. The threshold for meaningful within-person change is estimated to be 5 points. | Up to Approximately 24 months | 
| Absolute Score and Change from Baseline in PGIT-AD | PGIT-AD is a single item patient self-administered instrument designed to assess patient satisfaction or dissatisfaction with their current treatment for atopic dermatitis based on the following question: Overall, how satisfied or dissatisfied are you with your current treatment for atopic dermatitis?. Response options range from 1 (extremely dissatisfied) to 7 (extremely satisfied). | Up to Approximately 24 Months | 
| Change from Baseline in Flare Frequency and Duration | Participants are asked to provide the number of flares in the previous 6 months, and the average duration of flares in the previous 6 months. Participants are asked if currently experiencing an atopic dermatitis flare. Flare is defined as a sudden worsening of AD requiring treatment escalation and/or additional medical advice. | Up to Approximately 24 Months | 
| Change from Baseline in the Number of AD-Related Physician Office or Hospital Visits | Participants are asked the number of AD-related physician office visits in the previous 6 months and the number of AD-related hospital visits in the previous 6 months. | Up to Approximately 24 Months | 
| Absolute Score and Change from Baseline in Work Productivity and Activity Impairment Index for Atopic Dermatitis (WPAI-AD) | The Work Productivity and Activity Impairment Index for Atopic Dermatitis (WPAI-AD) is a validated instrument used to measure loss of productivity at work and impairment in daily activities over the past 7 days. The questionnaire includes four items: absenteeism, presenteeism, overall work impairment, and activity impairment, that range from 0% to 100%, with higher values indicating greater impairment. While absenteeism represents the percentage of work time missed due to AD, presenteeism represents the percentage of impairment while at work due to AD. Overall work impairment represents the total percentage of work time missed due to either absenteeism or presenteeism (since those are mutually exclusive). Activity impairment represents the percentage of impairment during daily activities other than work. The 4 items are all evaluated using an 11-point Likert-type scale from 0 (no effect) to 10 (completely prevented), and the scores are multiplied by ten to arrive at a percentage. | Up to Approximately 24 Months |

Four AD disease characteristics (erythema, thickness [induration, papulation, edema], scratching [excoriation], and lichenification) are each assessed for severity by the investigator on a scale of 0 (absent) through 3 (severe). In addition, the area of AD involvement is assessed as a percentage by body area of head, trunk (including the genital area), upper extremities, and lower extremities (including the buttocks), 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%). The EASI score ranges from 0-72 points with an MCID of 6.6 points. Published score bands: clear (0), almost clear (0.1-1.0), mild AD (1.1-7.0), moderate AD (7.1-21.0), severe AD (21.1-50.0), very severe AD (50.1-72.0). | Up to Approximately 24 months |

Item scores (0 to 4) are added to provide a total score range of 0 to 28. The total score reflects disease-related morbidity, and differentiates between clear/almost clear (0-2 points), mild (3-7 points), moderate (8-16 points), severe (17-24 points) and very severe (25-28 points) AD.
