Abrocitinib may improve itch and quality of life in patients with itch-dominant atopic dermatitis.

ABSTRACT:

Background

Patients with atopic dermatitis (AD) exhibit heterogeneous clinical phenotypes, reflecting different combinations of itch and lesional severity. AD with severe itch but clear-moderate lesions, also known as itch-dominant AD, is a common clinical phenotype.

Objectives

To evaluate abrocitinib efficacy in patients with moderate-to-severe AD who have itch-dominant AD.

Methods

This post hoc analysis includes pooled data from clinical trials of patients with moderate-to-severe AD receiving abrocitinib (100 or 200 mg) as monotherapy (phase 2b; phase 3 JADE MONO-1 and JADE MONO-2) or in combination with topical therapy (phase 3 JADE COMPARE). Data from the ongoing long-term JADE EXTEND trial (data cutoff April 2020) were also evaluated. Itch-dominant AD was defined as baseline Peak Pruritus Numerical Rating Scale (PP-NRS) score of 7-10 and Investigator's Global Assessment of 0-3 or Eczema Area and Severity Index of 0‒21. Assessments included a ≥4-point improvement in PP-NRS (PP-NRS4), PP-NRS score of 0 (no itch) or 1 (little itch) in patients with PP-NRS score ≥2 at baseline, ≥4-point improvement from baseline in Patient-Oriented Eczema Measure (POEM-4), Patient Global Assessment (PtGA) of clear or almost clear, and Dermatology Life Quality Index (DLQI) score of 0 or 1 (no impact or little impact of AD on quality of life [QoL]).

Results

In the pooled monotherapy trials, 37% of patients had itch-dominant AD at baseline. As early as Week 2, more patients with itch-dominant AD achieved PP-NRS4 with abrocitinib 100 mg (35%) and abrocitinib 200 mg (57%) versus placebo (7%); 6% and 22% versus 0%, respectively, achieved PP-NRS 0/1. More patients achieved a PtGA of clear/almost clear at Week 12 with abrocitinib 100 mg (28%) and abrocitinib 200 mg (45%) than placebo (9%). Additionally, abrocitinib led to clinically meaningful improvements in POEM and DLQI. Most patients with itch-dominant AD experienced itch improvement over time with abrocitinib monotherapy or with concomitant topical therapy; 86%-87% and 62%-67% of patients had no itch-moderate itch and clear-moderate lesions by weeks 24 and 48, respectively.

Conclusions

Abrocitinib is highly efficacious in patients with itch-dominant AD, demonstrating rapid, deep, and sustained improvements in itch and clinically meaningful improvements in patients' QoL.

Project description:Background and objectiveAbrocitinib is a Janus kinase 1 inhibitor in development for the treatment of atopic dermatitis (AD). This work characterized orally administered abrocitinib population pharmacokinetics in healthy individuals, patients with psoriasis, and patients with AD and the effects of covariates on abrocitinib exposure.MethodsAbrocitinib concentration measurements (n = 6206) from 995 individuals from 11 clinical trials (seven phase I, two phase II, and two phase III) were analyzed, and a non-linear mixed-effects model was developed. Simulations of abrocitinib dose proportionality and steady-state accumulation of maximal plasma drug concentration (Cmax) and area under the curve (AUC) were conducted using the final model.ResultsA two-compartment model with parallel zero- and first-order absorption, time-dependent bioavailability, and time- and dose-dependent clearance best described abrocitinib pharmacokinetics. Abrocitinib coadministration with rifampin resulted in lower exposure, whereas Asian/other race coadministration with fluconazole and fluvoxamine, inflammatory skin conditions (psoriasis/AD), and hepatic impairment resulted in higher exposure. After differences in body weight are accounted for, Asian participants demonstrated a 1.43- and 1.48-fold increase in Cmax and AUC, respectively. The overall distribution of exposures (Cmax and AUC) was similar in adolescents and adults after accounting for differences in total body weight.ConclusionsA population pharmacokinetics model was developed for abrocitinib that can be used to predict abrocitinib steady-state exposure in the presence of drug-drug interaction effects or intrinsic patient factors. Key covariates in the study population accounting for variability in abrocitinib exposures are Asian race and adolescent age, although these factors are not clinically meaningful.Clinical trial numbersNCT01835197, NCT02163161, NCT02201524, NCT02780167, NCT03349060, NCT03575871, NCT03634345, NCT03637790, NCT03626415, NCT03386279, NCT03937258.

Project description:BackgroundA significant improvement in clinical signs was demonstrated with abrocitinib relative to placebo in adolescents with moderate-to-severe atopic dermatitis (AD) in three phase 3, randomized, double-blinded, placebo-controlled studies (JADE TEEN [ClinicalTrials.gov, NCT03796676], JADE MONO-1 [NCT03349060] and JADE MONO-2 [NCT03575871]).ObjectivesTo evaluate the impact of abrocitinib on patient-reported signs/symptoms, including sleep loss and quality of life among adolescents with moderate-to-severe AD.MethodsJADE TEEN, JADE MONO-1 and JADE MONO-2 were conducted in the Asia-Pacific region, Europe and North America and included patients aged 12-17 years with moderate-to-severe AD and inadequate response to ≥ 4 consecutive weeks of topical medication or treatment with systemic therapy for AD. Patients were randomly assigned (1 : 1 : 1, JADE TEEN; 2 : 2 : 1, JADE MONO-1/-2) to receive once-daily oral abrocitinib (200 or 100 mg) or placebo for 12 weeks in combination with topical therapy (JADE TEEN) or as monotherapy (JADE MONO-1/-2). Data from adolescent patients in JADE MONO-1/-2 were pooled for these analyses.ResultsAt week 12, more adolescents treated with abrocitinib (200 or 100 mg) vs. placebo achieved a ≥ 4-point improvement from baseline in the Patient-Oriented Eczema Measure in JADE TEEN (83.9% and 77.0% vs. 60.2%) and JADE MONO-1/-2 (83.0% and 69.4% vs. 43.5%) and a ≥ 6-point improvement from baseline in the Children's Dermatology Life Quality Index in JADE TEEN (73.8% and 67.5% vs. 56.5%) and JADE MONO-1/-2 (70.0% and 57.1% vs. 19.0%). Significant improvements in SCORing Atopic Dermatitis Visual Analog Scale for sleep loss scores were demonstrated with abrocitinib vs. placebo at weeks 2-12 in JADE TEEN and JADE MONO-1/-2.ConclusionsPatient-reported signs/symptoms, including reduction of sleep loss and quality of life, were substantially improved with abrocitinib monotherapy or combination therapy relative to placebo in adolescents with moderate-to-severe AD.

Project description:BackgroundSkin pain in atopic dermatitis (AD) increases with disease severity and is associated with substantial quality of life (QoL) burden.ObjectivesThe aim of the study was to evaluate abrocitinib efficacy on skin pain and QoL in adults and adolescents with moderate-to-severe AD.MethodsThis post hoc analysis included data with abrocitinib administered as monotherapy (pooled phase 2b [NCT02780167] and phase 3 JADE MONO-1 [NCT03349060] and JADE MONO-2 [NCT03575871]) or in combination with topical therapy (phase 3 JADE COMPARE [NCT03720470] and JADE TEEN [NCT03796676]). Patients received oral, once-daily abrocitinib 200 mg, abrocitinib 100 mg, or placebo for 12 or 16 weeks (JADE COMPARE). Skin pain was rated using the Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD) skin pain Numerical Rating Scale (NRS) item ("How painful was your skin over the past 24 h?") on a scale from 0 (not painful) to 10 (extremely painful). Itch (Peak Pruritus NRS) and QoL (Dermatology Life Quality Index or Children's Dermatology Life Quality Index) were assessed. Least squares mean (LSM) change from baseline was analyzed using mixed-effects repeated measures modeling.ResultsA total of 1,822 patients (monotherapy pool, n = 942; JADE COMPARE, n = 595; and JADE TEEN, n = 285) were analyzed. LSM change from baseline in PSAAD skin pain score was significantly greater with abrocitinib versus placebo from week 2 through week 12 or 16 across all 3 study populations and occurred in a dose-dependent manner. A greater proportion of patients achieved a ≥4-point improvement from baseline in PSAAD skin pain score with abrocitinib (200 mg and 100 mg) versus placebo in the monotherapy pool (56% and 38% vs. 12%; week 12), JADE COMPARE (72% and 52% vs. 26%; week 16), and JADE TEEN (51% and 60% vs. 31%; week 12). Additionally, a greater proportion of patients achieved a stringent threshold of skin pain improvement (PSAAD skin pain score <2) with abrocitinib versus placebo. Adults and adolescents who achieved a ≥4-point improvement in skin pain reported greater QoL improvement than those who did not achieve a ≥4-point improvement. A positive correlation (≥0.3) was observed between skin pain and QoL and separately between skin pain and itch across the 3 study populations.ConclusionAbrocitinib as monotherapy or in combination with topical therapy improved skin pain and was associated with improved QoL in both adults and adolescents with moderate-to-severe AD across all evaluated studies.

Project description:BackgroundAbrocitinib, 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.ObjectivesThis 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.MethodsJADE 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.ResultsAs 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.ConclusionsAbrocitinib 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.
