BACKGROUND: Abrocitinib efficacy by prior dupilumab response status in patients with moderate-to-severe atopic dermatitis (AD) has not previously been assessed in phase 3 studies.OBJECTIVE: Examine efficacy and safety of abrocitinib among patients who received prior dupilumab.METHODS: Patients with moderate-to-severe AD received abrocitinib 200 mg or 100 mg once-daily in JADE EXTEND (phase 3 extension) after dupilumab in double-blind, placebo-controlled phase 3 JADE COMPARE.RESULTS: Among prior dupilumab responders, ≥75% improvement in Eczema Area and Severity Index (EASI-75) was achieved in 93.5% and 90.2% of patients who received 12 weeks of abrocitinib 200 mg and 100 mg, respectively; ≥4-point improvement in Peak Pruritus Numerical Rating Scale (PP-NRS4) was achieved in 89.7% and 81.6%, respectively. Among prior dupilumab nonresponders, EASI-75 was achieved with abrocitinib 200 mg and 100 mg in 80.0% and 67.7% and PP-NRS4 in 77.3% and 37.8%, respectively. Most common adverse events among abrocitinib-treated patients were nasopharyngitis, nausea, acne, and headache. Conjunctivitis occurred less frequently with abrocitinib in comparison to prior dupilumab.LIMITATIONS: Short-term, 12-week analysis; no placebo arm.CONCLUSION: Efficacy and safety profile of abrocitinib in JADE EXTEND supports the role of abrocitinib as a treatment for patients with moderate-to-severe AD, regardless of prior dupilumab response status.

Abrocitinib, an oral Janus kinase 1 inhibitor, provided significant itch relief by week 2 in patients with moderate-to-severe atopic dermatitis (AD) in the phase III JADE COMPARE trial.This post-hoc analysis of JADE COMPARE aimed to further characterize itch response and determined whether early itch relief could predict subsequent improvements in AD severity.JADE COMPARE was a randomized, double-blind, double-dummy, placebo-controlled trial. Adult patients (aged ≥ 18 years) with moderate-to-severe AD were randomly assigned to receive oral abrocitinib 200 mg or 100 mg once daily, subcutaneous dupilumab 300 mg every other week (after a 600-mg loading dose), or placebo, plus medicated topical therapy for 16 weeks. Assessments were ≥ 4-point improvement in Peak Pruritus Numerical Rating Scale (PP-NRS4) from days 2 to 15, Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA) response, and Dermatology Life Quality Index (DLQI) scores at week 12. Association between week 2 PP-NRS4 and efficacy at week 12 was evaluated by chi-squared tests. The predictive value of early response for later efficacy was assessed by area under the receiver operating characteristic curve.As early as day 4 after treatment, a significantly greater proportion of patients achieved PP-NRS4 response with abrocitinib 200 mg (18.6%) versus dupilumab (5.6%; p 0.001) and placebo (6.0%; p 0.003). A similar trend was observed with abrocitinib at the 100-mg dose, with significantly greater PP-NRS4 response rates versus placebo as early as day 9. With both doses of abrocitinib, week 12 IGA 0/1, EASI-75, EASI-90, and DLQI 0/1 response rates were greater in week 2 PP-NRS4 responders than nonresponders; no differences were observed between week 2 PP-NRS4 responders and nonresponders in the dupilumab and placebo groups. Early improvement in PP-NRS at week 2 was associated with skin clearance at week 12 in abrocitinib-treated patients.Abrocitinib resulted in rapid relief from itch in patients with moderate-to-severe AD, with significant improvement in itch as early as day 4 after treatment with abrocitinib 200 mg compared with dupilumab and placebo. Abrocitinib-induced itch relief by week 2 was associated with subsequent improvements at week 12. [Video abstract available.] TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03720470. Early itch response with abrocitinib is associated with later efficacy outcomes in patients withmoderate-to-severe atopic dermatitis: subgroup analysis of the randomized phase III JADE COMPARE trial (MP4 335,375kb).Atopic dermatitis (AD), also called atopic eczema, is a skin disease that affects people throughout their lives. About 10% of adults worldwide have AD. Itch is the most bothersome symptom reported by people with AD and scratching this itch can damage the skin, resulting in painful sores. It is unknown if relief from itch can influence other symptoms of AD. We analyzed data from the JADE COMPARE study, which included 837 people who received treatment with abrocitinib, dupilumab or placebo. We studied how fast itch relief occurred after people received these treatments. We also wanted to study if rapid itch relief was associated with improvement in other signs of AD later on with continued treatment. We found that as early as 4 days after treatment, abrocitinib 200 mg provided significant relief from itch compared with dupilumab or placebo. People who had rapid itch relief within 2 weeks of treatment with abrocitinib were more likely to have clear or almost clear skin and improved quality of life after 12 weeks of continued treatment with abrocitinib. Rapid itch relief did not appear to increase the likelihood of clear skin at week 12 in people who received dupilumab. Larger studies are needed to confirm this result. This study provides important evidence for physicians as they analyze itch relief and determine treatment options for people with AD.

Abrocitinib, a once-daily, oral Janus kinase 1 selective inhibitor, was shown to be an effective treatment for moderate-to-severe atopic dermatitis in phase 2 b/3 monotherapy trials. These analyses included data for Investigator’s Global Assessment responder (clear [0] or almost clear [1] with ≥2-grade improvement) and nonresponder patients with moderate-to-severe atopic dermatitis who received abrocitinib (200 mg or 100 mg) or placebo in three abrocitinib monotherapy trials (phase 2 b, NCT02780167; two phase 3, NCT03349060/JADE MONO-1 and NCT03575871/JADE MONO-2). Outcomes measuring skin clearance, itch, and quality of life were evaluated. Both nonresponders (n = 548) and responders (n = 260) treated with abrocitinib had rapid and clinically meaningful improvement in skin clearance, itch, and quality of life compared with placebo. Patients with moderate-to-severe atopic dermatitis treated with abrocitinib who did not achieve an Investigator’s Global Assessment 0/1 response at week 12 still experienced rapid, clinically meaningful improvements across several other validated measures of efficacy and quality of life.

Emerging treatments for moderate-to-severe atopic dermatitis (AD) may provide greater and faster improvement in AD signs and symptoms than current therapies.To examine JADE COMPARE (NCT03720470) data using stringent efficacy end points.Adults with moderate-to-severe AD were randomly assigned 2:2:2:1 to receive oral abrocitinib 200 or 100 mg once daily, subcutaneous dupilumab 300 mg every 2 weeks (600-mg loading dose), or placebo, with medicated topical therapy for 16 weeks. Stringent response thresholds were applied for Eczema Area and Severity Index (EASI), Investigator's Global Assessment, Dermatology Life Quality Index, Peak Pruritus Numerical Rating Scale, and Night Time Itch Scale severity.At week 16, 48.9%, 38.0%, and 38.8% of the abrocitinib 200-mg, 100-mg, and dupilumab groups, respectively, achieved greater than or equal to 90% improvement from baseline in EASI versus 11.3% placebo; 14.9%, 12.6%, and 6.5% achieved Investigator's Global Assessment 0 (clear) versus 4.8% placebo; 29.7%, 21.6%, and 24.0% achieved Dermatology Life Quality Index 0/1 (no/minimal impact on quality of life) versus 10.6% placebo; and 57.1%, 44.5%, and 46.1% achieved Night Time Itch Scale severity 0/1 (no/minimal night-time itch) versus 31.9% placebo. Kaplan-Meier median time to greater than or equal to 90% improvement from baseline in EASI was 59, 113, and 114 days in the abrocitinib 200-mg, 100-mg, and dupilumab groups, respectively, and was not evaluable for placebo; median time to Peak Pruritus Numerical Rating Scale 0/1 (no/very minimal itch) was 86 and 116 days for abrocitinib 200-mg and dupilumab groups, respectively, and was not evaluable for abrocitinib 100-mg and placebo groups.A greater proportion of patients treated with abrocitinib than placebo had almost complete control of AD signs and symptoms.
