STUDY DESIGN
Over 1700 adult and adolescent patients took part in the ARCADIA Phase 3 clinical trials for atopic dermatitis1,2
ARCADIA 1 and ARCADIA 2 were identically designed, multicenter, randomized, double-blind, parallel-group, placebo-controlled, Phase 3 studies that evaluated NEMLUVIO in patients aged ≥12 years with moderate-to-severe AD not adequately controlled with TCS/TCI.1,2*
TO CAPTURE THE REALITY OF MANY PATIENTS WITH AD, THE ARCADIA TRIALS ONLY INCLUDED THOSE WHO FAILED WITH TCS/TCI1-5
ENROLLMENT
Patients with moderate-to-severe AD defined by1,2:
- PP-NRS ≥4
- IGA ≥3
- EASI ≥16
- BSA ≥10%
SCREENING AFTER
2-4 WEEKS OF TCS/TCI
Patients who were no longer moderate to severe after a run-in period of 2-4 weeks of TCS/TCI did not continue into the ARCADIA trials1,2
CONTINUATION
Only patients who were still moderate to severe after 2-4 weeks of TCS/TCI continued into the ARCADIA trials1,2
CO-PRIMARY ENDPOINTS AT WEEK 161
Proportion of patients achieving:
- EASI response (≥75% improvement in EASI from baseline)
- IGA success (clear [IGA 0] or almost clear [IGA 1] skin and a ≥2-point reduction from baseline)
SELECT SECONDARY ENDPOINTS1
Proportion of patients achieving:
- PP-NRS improvement ≥4 points from baseline at Weeks 1, 2, 4, and 16
- PP-NRS <2 at Weeks 4 and 16
- SD-NRS improvement ≥4 points from baseline at Week 16
INVESTIGATOR GLOBAL ASSESSMENT (IGA)1,6
- Clinician-reported outcome to assess the severity of AD
- Scale ranges from 0 (clear) to 4 (severe)
- Treatment success defined as 0 (clear) or 1 (almost clear) and a ≥2-point improvement from baseline
ECZEMA AREA AND SEVERITY INDEX (EASI-75)1,7
- Clinician-reported outcome to evaluate the severity of AD
- EASI integrates body surface areas and the intensity of lesions into 1 composite score
- EASI-75 = ≥75% improvement in EASI score from baseline
PEAK PRURITUS NUMERICAL RATING SCALE (PP-NRS)1,6
- Patient-reported outcome designed to measure the worst itch over the previous 24-hour period
- Treatment success defined as at least a 4-point improvement from baseline
SCORAD (SEVERITY SCORING OF ATOPIC DERMATITIS)2,8
- VAS (visual analog scale; component pruritus)
- Patient-reported outcome to assess itch severity in AD
- Evaluated on a 0 to 10 scale based on average assessment for the previous 3 days or nights
BODY SURFACE AREA (BSA)1,2,8
- Clinician-reported outcome to evaluate the extent of AD
- BSA measures the percent of the body's surface that is visually affected by AD
- Patients with a BSA ≥10 (10% of their body surface affected) were included in the ARCADIA trials
ARCADIA Long-Term Extension (LTE) Study Design
The ARCADIA LTE is an ongoing prospective, multicenter, open-label study. The objective is to assess the long-term safety and efficacy of NEMLUVIO in adults and adolescents aged ≥12 years with moderate-to-severe AD from baseline up to 200 weeks.1,3
ARCADIA 1 and 2 patients who received the rescue medication during the study period, nonresponders at Week 16, patients who received rescue medications prior to a 48-week visit, and patients who completed the maintenance period were eligible for the LTE.1,3
The ARCADIA LTE enrolled patients from ARCADIA 1 and 2 plus patients from a blinded lead-in study, for a total of 1751 patients. As of September 2022,† 741 patients completed a Week 56 assessment.3

Concomitant low- or medium-potency TCS and/or TCI were administered for at least 14 days prior to baseline and continued during the trial. Based on disease activity, these concomitant therapies could be tapered and/or discontinued at investigator discretion.1,2
Interim analysis cutoff date was September 30, 2022.3
