Brief summary
The purpose of this study is to learn about the safety and effects of the study medicine called etrasimod for the possible treatment of atopic dermatitis (AD), also called eczema, in adults who have already tried AD treatments taken by mouth or by injection that work all over the body. These adults can have moderate to severe AD. This study is seeking participants who: * have AD for at least 1 year * have moderate-to-severe AD * have tried treatments that work all over the body and saw no effects * are willing to apply a moisturizer at least once daily during the study This is a 2-part study that is only selecting about 60 participants for Part 1 as of now. In Part 1, half of the participants will receive etrasimod, a pill to be taken by mouth once daily. The other half will receive a placebo, a pill that looks like etrasimod but has no medicine also taken by mouth once daily. No one will know what treatment the participant is taking. The Sponsor will compare participant experiences of those taking etrasimod to those taking placebo for 16 weeks. This will help determine if the study medicine is safe and effective. After the first 16 weeks, some participants may continue the study knowing they are taking etrasimod for an additional 52 weeks. Those participating for just the first 16-weeks, will need to visit the study clinic at least 6 times during the study (about every 4 weeks), and will have to come for 2 safety follow up visits at 2nd and 4th week after the last dose of study medicine. People who want to and can continue for an additional 52 weeks will need to visit the study clinic for at least 6 more visits making 12 total visits over 68 weeks followed by 2 safety follow up visits at the 2nd and 4th week after the last dose of study medicine. In Part 2 of the study, around 340 more participants will be participating. Everyone will receive etrasimod pills once daily for 52 weeks. Participants will need to go to the study clinic at least 9 times after which they will have to go for 2 more safety follow up visits at the 2nd and 4th weeks after the last dose of study medicine. At every study visit in Part 1 and Part 2, the focus will be on signs and symptoms of AD (like lesions, itch, and pain) as well as general health and overall side effects. Blood samples and vital signs will be taken at every visit. Due to the way the study medicine works, the in-study clinic visit will last at least 4 hours on Day 1 (Part 1 and Part 2) and Week 16 (Part 1).

Masking description
PART 1 Double Blind portion (Day 1 through Week 16): all parties are blinded to treatment. PART 1 Open Label Extension portion: All parties will be aware participant is taking etrasimod for up to an additional 52 weeks. PART 2 Open Label All parties will be aware participant is taking etrasimod for 52 weeks.
Intervention model description
Part 1: Approximately 60 participants with moderate-to-severe AD with a history of prior systemic treatment failure will be randomized (1:1 ratio) in a double blind (DB) manner to receive etrasimod 2 mg or placebo orally, once daily, for 16 weeks. Randomization will be stratified by disease severity as measured by IGA score (3 \[moderate AD\], 4 \[severe AD\]) at baseline. After DB period, participants may be given the option to continue in an open label extension (OLE) phase whereby they will receive etrasimod 2 mg (tablet) for up to an additional 52 weeks. Part 2: Approximately 340 additional participants will be enrolled to receive etrasimod 2 mg orally, once daily, for 52 weeks in an open-label manner.
Eligibility
Inclusion criteria
Participants must meet the following key inclusion criteria to be eligible for enrollment into the study: 1\. Age 18-80 at screening (or minimum age of consent according to local regulations). 2 Chronic AD (also known as atopic eczema) that was diagnosed at least 1 year prior to Screening and meets Hanifin and Rajka criteria at screening).1 3. Moderate to severe AD: 1. IGA score ≥3 (on the 0 to 4 IGA scale, in which 3 = moderate and 4 = severe) at screening and baseline (Day 1) 2. BSA ≥10% of AD involvement at screening and baseline (Day 1) 3. Eczema Area and Severity Index (EASI) ≥16 at screening and baseline (Day 1) 4.

Willing to apply a topical emollient/moisturizer at least once daily for ≥1 week prior to baseline (Day 1) and willing to maintain consistent (ie, no change in type, frequency, or application) daily application over the course of the study.
Exclusion criteria
Participants are excluded from the study if any of the following criteria apply: Medical Conditions: 1. Presence of confounding factors: * Skin conditions (eg, psoriasis, seborrheic dermatitis) that may interfere with evaluation of AD or assessment of treatment response as deemed by the investigator. * Current significant active infection or requiring a treatment for infection that may interfere with the assessment of AD. 2. Hypersensitivity to etrasimod or any of the excipients. 3. Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.

Part 1, OLE Period: Number of Participants With TEAEs (All Causality)
An AE was any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Treatment-emergent are events between first dose of study drug and up to last dose that were absent before treatment or that worsened relative to pretreatment state.
Time frame: OLE Period: First dose of study drug in OLE period up to 4 weeks after last dose in OLE period (up to maximum of 56 Weeks)
Population: Safety analysis set included all participants who received at least 1 dose of study intervention (i.e., Etrasimod or placebo). Participants were analyzed in the treatment groups as they were randomized.

Part 1, DB Period: Percentage of Participants Who Achieved >=75% Reduction From Baseline in Eczema Area and Severity Index (EASI) Score (EASI-75) at Week 16
EASI-75 response was defined as a 75% reduction or greater in EASI score from Baseline to Week 16. EASI quantified severity of AD based on severity of lesion clinical signs and percentage (%) of body surface area (BSA) affected. Severity of clinical signs of AD lesions (erythema \[E\], induration/papulation \[I\], excoriation \[Ex\] and lichenification \[L\]) were scored separately for each of 4 body regions (head and neck, upper limbs, trunk \[including axillae and groin)\] and lower limbs \[including buttocks\]) on a 4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score was based on % BSA with AD in body region: 0 (0%), 1 (\>0 to \<10%), 2 (10 to \<30%), 3 (30 to \<50%), 4 (50 to \<70%), 5 (70 to \<90%) and 6 (90 to 100%). Total EASI score =0.1\*Ah\*(Eh+Ih+Exh+Lh) + 0.2\*Au\*(Eu+Iu+ExU+Lu) + 0.3\*At\*(Et+It+Ext+Lt) + 0.4\*Al\*(El+Il+Exl+Ll); A = EASI area score; h = head and neck; u = upper limbs; t = trunk; l = lower limbs.
Time frame: DB Period: Week 16
Population: FAS included all participants who were randomized to the study irrespective of whether they received any dose of study intervention (i.e., etrasimod or placebo). Participants were analyzed in the treatment groups as they were randomized.
