Improvements In Itch Research Articles

Chronic kidney disease-associated pruritus and quality of life with difelikefalin treatment: a post hoc analysis of phase 3 data using the Skindex-10 questionnaire.

Pruritus is a common condition in chronic kidney disease (CKD), especially for patients receiving haemodialysis. CKD-associated pruritus (CKD-aP) can be distressing and have a negative impact on quality of life (QoL). This post hoc analysis aimed to assess the relationship between pruritus relief and QoL. Data from phase 3 trials [(NCT03422653, NCT03636269 grouped), and NCT03998163] of the novel antipruritic difelikefalin (N=914) were used to assess the relationship between reductions in pruritus intensity at Week 12 (24-h Worst Itching Intensity Numeric Rating Scale; WI-NRS), perceived improvement in itch (Patient Global Impression of Change, PGI-C) and pruritus-related QoL (Skindex-10 questionnaire). Patients receiving difelikefalin had greater improvements in Skindex-10 total scores than those receiving placebo [LS mean treatment difference -3.4; 95% confidence interval (CI) -5.5, -1.3; P=.002] and greater improvements across Skindex-10 domains (disease, mood and social functioning) at Week 12. In patients receiving difelikefalin, those with clinically meaningful improvements in pruritus (≥3-point reduction in WI-NRS score) at Week 12 had a greater improvement in Skindex-10 total score (mean difference 14.2; 95% CI 11.0, 17.3; P<.001) and Skindex-10 domains than those with a <3-point reduction in WI-NRS score. Improvements in Skindex-10 total scores correlated with PGI-C. Improvements in pruritus intensity following 12 weeks of treatment with difelikefalin were associated with improvements in QoL. Larger improvements in Skindex-10 scores were seen in patients with a greater reduction in pruritus intensity, indicating that improvements in pruritus are associated with a range of factors, such as mood and social functioning, that affect pruritus-related QoL.

Effect of Omega-3 Polyunsaturated Fatty Acid Supplementation on Clinical Outcome of Atopic Dermatitis in Children.

The use of omega-3 fatty acids (omega-3 FA) in the treatment of atopic dermatitis (AD) is an area of ongoing research. Some studies suggest that dietary supplementation with omega-3 FA can help manage symptoms of AD by reducing lesion severity, skin inflammation, dryness and itching, while others show no significant beneficial effect. The aim of this study was to evaluate the effect of omega-3 FA from fish oil in combination with gamma-linolenic acid (GLA) from blackcurrant seed oil in children with AD. This is a longitudinal, prospective, randomized, triple blind, placebo-controlled parallel clinical trial. The study was conducted during the 2-year period throughout autumn, winter, and spring, avoiding the summer when AD usually improves. Children were randomized to receive the active study product (Mega Kid®) containing a specific blend of omega-3 and omega-6 fatty acids or placebo. The primary outcomes were changes in severity of AD measured using SCORing Atopic Dermatitis (SCORAD), patient-oriented SCORAD (PO-SCORAD) and the difference in topical corticosteroid (TCS) use. The secondary outcomes were changes in itch intensity, sleep quality and Family Dermatology Life Quality Index (FDLQI). Data were analyzed for 52 children (26 in the intervention group and 26 in the placebo group). In children receiving the active product, intention-to-treat analysis showed that after 4 months of treatment, there was a significant decrease in the SCORAD index (from median 42 to 25, p < 0.001) and the use of topical corticosteroids (from median 30 to 10 mg/month, p < 0.001), but also significant improvements in itch, sleep quality, and overall quality of life. Omega-3 fatty acids in combination with GLA and vitamin D may decrease symptoms and were associated with an improvement clinical picture of AD in children. Therefore, we can conclude that supplementation with this specific combination could be considered a safe and effective intervention that may significantly reduce the severity of AD in pediatric patients.

Nemolizumab with concomitant topical therapy in adolescents and adults with moderate-to-severe atopic dermatitis (ARCADIA 1 and ARCADIA 2): results from two replicate, double-blind, randomised controlled phase 3 trials

Nemolizumab, an interleukin (IL)-31 receptor subunit α antagonist, inhibits the IL-31 pathway of itch and skin inflammation in atopic dermatitis. Two international phase 3 studies were done to assess the efficacy and safety of nemolizumab in atopic dermatitis. In this Article we report results for the 16-week initial treatment period of both trials. ARCADIA 1 and ARCADIA 2 were identical 48-week randomised, double-blind, placebo-controlled phase 3 trials in adult and adolescent participants (aged ≥12 years) with moderate-to-severe atopic dermatitis, associated pruritus, and inadequate response to topical steroids. Participants were enrolled from 281 clinics, hospitals, and academic centres in 22 countries across both trials, and were randomly assigned (2:1) to receive nemolizumab 30 mg subcutaneously (baseline loading dose 60 mg) or matching placebo once every 4 weeks with background topical corticosteroids (TCS) with or without topical calcineurin inhibitors (TCI; ie, TCS-TCI background treatment). Randomisation was done via interactive response technology and stratified by baseline disease and pruritus severity. Study staff and participants were masked throughout the study, with outcome assessors masked until database lock. Coprimary endpoints at week 16 post-baseline were Investigator's Global Assessment (IGA) success (score of 0 [clear skin] or 1 [almost clear skin] with a ≥2-point improvement from baseline) and at least 75% improvement in Eczema Area and Severity Index score from baseline (EASI-75 response). Outcome rates were compared between groups with the Cochran-Mantel-Haenszel test adjusting for randomisation strata. The key secondary endpoints were the proportion of participants with Peak Pruritus Numerical Rating Scale (PP-NRS) score improvement of at least 4 points at weeks 1, 2, 4, and 16; PP-NRS score below 2 at weeks 4 and 16; Sleep Disturbance Numerical Rating Scale score improvement of at least 4 points at week 16; EASI-75 response plus PP-NRS score improvement of at least 4 points at week 16; and IGA success plus PP-NRS score improvement of at least 4 points at week 16. Efficacy analyses were done on an intention-to-treat basis; safety analyses included all participants who received one dose of nemolizumab or placebo. Both studies are completed (ClinicalTrials.gov: ARCADIA 1, NCT03985943 and ARCADIA 2, NCT03989349). Between Aug 9, 2019, and Nov 2, 2022, 1728 participants were enrolled across both trials: 1142 were allocated to nemolizumab plus TCS-TCI (620 in ARCADIA 1 and 522 in ARCADIA 2) and 586 to placebo plus TCS-TCI (321 in ARCADIA 1 and 265 in ARCADIA 2). ARCADIA 1 included 500 (53%) male participants and 441 (47%) female participants, and ARCADIA 2 included 381 (48%) male participants and 406 (52%) female participants. Mean age ranged from 33·3 (SD 15·6) years to 35·2 (17·0) years across the treatment groups. Both trials met the coprimary endpoints; at week 16, a greater proportion of participants receiving nemolizumab plus TCS-TCI versus placebo plus TCS-TCI had IGA success (ARCADIA 1: 221 [36%] of 620 vs 79 [25%] of 321, adjusted percentage difference 11·5% [97·5% CI 4·7-18·3], p=0·0003; ARCADIA 2: 197 [38%] of 522 vs 69 [26%] of 265, adjusted difference 12·2% [4·6-19·8], p=0·0006) and an EASI-75 response (ARCADIA 1: 270 [44%] vs 93 [29%], adjusted difference 14·9% [7·8-22·0], p<0·0001; ARCADIA 2: 220 [42%] vs 80 [30%], adjusted difference 12·5% [4·6-20·3], p=0·0006). Significant benefits were observed with nemolizumab for all key secondary endpoints including improvement in itch, as early as week 1, and sleep improvement by week 16. The safety profile was similar between nemolizumab plus TCS-TCI and placebo plus TCS-TCI. In the safety sets, 306 (50%) of 616 participants (ARCADIA 1) and 215 (41%) of 519 participants (ARCADIA 2) who received nemolizumab plus TCS-TCI had at least one treatment-emergent adverse event (serious treatment-emergent adverse events in six [1%] and 13 [3%], respectively); and 146 (45%) of 321 (ARCADIA 1) and 117 (44%) of 263 (ARCADIA 2) who received placebo plus TCS-TCI had at least one treatment-emergent adverse event (serious treatment-emergent adverse events in four [1%] and three [1%], respectively). Ten serious treatment-emergent adverse events possibly related to nemolizumab were reported in five (1%) participants in ARCADIA 2. No deaths occurred. Nemolizumab plus TCS-TCI was efficacious and showed statistically and clinically significant improvements in inflammation and itch in adults and adolescents with moderate-to-severe atopic dermatitis. Nemolizumab might offer a valuable extension of current therapies if approved. Galderma.

Responder analysis using clinically meaningful thresholds: Post hoc analyses from randomized dupilumab clinical trials in patients with prurigo nodularis.

Prurigo nodularis (PN) is an intensely pruritic disease characterized by itchy nodules on the trunk/extremities; it is often accompanied by skin pain and sleep disruption with negative impacts on the quality of life (QoL). The patient-reported outcome (PRO) instruments, Worst Itch-Numeric Rating Scale (WI-NRS), Skin Pain-NRS, Sleep-NRS and Dermatology Life Quality Index (DLQI) have been psychometrically validated and the clinically meaningful within-patient improvement thresholds (responder definition) have been established through data pooled from the two Phase-3 trials (PRIME, NCT04183335 and PRIME2, NCT04202679) of dupilumab in adults with PN uncontrolled on topical therapies. To estimate the proportion of dupilumab-treated patients (vs. placebo) achieving clinically meaningful improvement in itch, skin pain, sleep and QoL, either alone or in combination, from the data pooled from PRIME and PRIME2 trials. The patient-level data pooled from the two Phase-3 trials (N = 311) were used for this post hoc analysis. Thresholds of clinically meaningful within-patient improvement in PRO instrument scores from baseline at Week 24 used for defining responders were 4 (WI-NRS and Skin Pain-NRS), 2 (Sleep-NRS) and 9 points (DLQI). The proportion of dupilumab-treated patients, versus placebo, achieving the thresholds, and the time taken to achieve the thresholds were evaluated for the individual and combination of PROs. Responder rates were significantly higher with dupilumab, versus placebo at Week 24 for WI-NRS (58.8% vs. 19.0%, p < 0.0001), Skin Pain-NRS (49.7% vs. 20.9%, p < 0.0001), Sleep-NRS (42.5% vs. 23.4%, p < 0.0001) and DLQI (64.7% vs. 22.8%, p < 0.0001). Proportion of patients achieving simultaneous improvement in symptoms and QoL (24.8% vs. 6.3%, p < 0.0001) were significantly higher in dupilumab-treated patients versus placebo. The time needed for achieving clinically meaningful improvement in symptoms were significantly lower in dupilumab-treated patients, versus placebo. Significantly greater proportion of dupilumab-treated patients with PN, versus placebo, demonstrated clinically meaningful improvements in PRO measures of symptoms and QoL.

#1857 Difelikefalin experience in a large dialysis organization in the US: one year follow-up on patients after completion of 12 weeks

Abstract Background and Aims Chronic kidney disease associated pruritis (CKD-aP) is a common disorder that negatively impacts a patient's quality of life. Itch can be self-reported using the Worst Itching Intensity Numerical Rating Scale (WI-NRS) where higher numbers indicate more severe itch. Difelikefalin (DFK) has been shown to reduce itch in hemodialysis (HD) patients with moderate to severe CKD-aP in clinical trials. Previously, we reported the real-world results of patients who completed 12 weeks of DFK treatment as part of routine clinical care. This current analysis describes the long-term treatment of these 295 patients. Method Fresenius Kidney Care (FKC) in-center HD patients aged 18-89 who received at least 1 dose of DFK before 15 Nov 2022 and were administered a WI-NRS before first DFK administration were assessed. Patients who received 30+ DFK administrations within 74-84 days were classified as complete and are the focus of this analysis. The current analysis focuses on the 3- to 12-month follow-up after first DFK administration to monitor for DFK discontinuation and severity of itch when DKF therapy is discontinued. Results Eighty-one percent of patients (238/295) were administered DFK doses beyond 90 days. These patients treated included 167 patients who received DFK continuously (doses between days 91-101) and 71 who restarted DFK after day 101. Most patients (62%, 148/238) were treated with DKF between days 354 and 365 and 90 (38%, 90/238) stopped before 354 days. Out of those not treated with DFK beyond 90 days (19%, 57/295), 26 patients died or were transferred outside of FKC and 1 received a kidney transplant. Out of the 84 patients previously reported with WI-NRS measured before DFK and during DFK WI-NRS, 29 had follow up WI-NRS scores during times without DFK doses. We observed a decrease in mean itch severity from 8.0 before DFK to 3.2 during DFK and then a return to higher itch severity after DFK was discontinued (7.3). Conclusion In a real-world analysis of patients who completed 12 weeks of DFK therapy, 81% of patients received further DKF administrations. Most patients were treated with DFK between days 354 and 365, although not all patients received continuous DFK therapy. In a subset 29 patients with WI-NRS scores before DFK, during DFK, and after discontinuation, improvements in itch were noted during DFK treatment and a return to severe itch after DFK discontinuation.

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

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. To evaluate abrocitinib efficacy in patients with moderate-to-severe AD who have itch-dominant AD. This post hoc analysis includes pooled data from clinical trials of patients with moderate-to-severe AD receiving abrocitinib (100 or 200mg) 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]). 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 100mg (35%) and abrocitinib 200mg (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 100mg (28%) and abrocitinib 200mg (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. 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.

Cedirogant in adults with psoriasis: a phase II, randomized, placebo-controlled clinical trial.

Dysregulated interleukin (IL)-17/IL-23 signalling contributes to psoriasis pathogenesis. Cedirogant is an inverse agonist of nuclear receptor ROR-gamma isoform 2 (RORyt), a key transcription factor responsible for IL-17 synthesis and a regulator of the T helper 17 cell lineage programme. To evaluate the efficacy and safety of cedirogant to treat moderate-to-severe psoriasis. In this phase IIb, multicentre, double-blind, 16-week study (NCT05044234), adults aged 18-65 years were randomized 1 : 1 : 1 : 1 to once-daily oral cedirogant 75 mg, 150 mg, 375 mg or placebo. Assessments included: ≥ 50%/75%/90%/100% improvement from baseline in Psoriasis Area and Severity Index (PASI 50/75/90/100), static Physician's Global Assessment 0/1, Psoriasis Symptoms Scale 0 and improvements in itch; adverse events (AEs); pharmacokinetics; and IL-17A/F biomarker levels. Efficacy results based on observed cases were summarized descriptively. Of 156 enrolled patients, most were male (70.5%); 39 patients were randomized to each treatment. Only 47 patients completed the study; the study was terminated early owing to preclinical findings. At week 16, PASI 75 achievement rates (primary endpoint) were 29%, 8% and 42% in the cedirogant 75-mg, 150-mg and 375-mg groups, respectively, and 0% in the placebo group. AE rates were similar in the cedirogant 75-mg, 150-mg and placebo groups, and higher in the cedirogant 375-mg group; most AEs were mild or moderate. Patients with psoriasis who received cedirogant showed PASI improvement, and cedirogant was generally well tolerated. The results should be interpreted in the context of early study termination. Cedirogant development has been discontinued.

Rapid and sustained improvements in itch and quality of life with upadacitinib plus topical corticosteroids in adults and adolescents with atopic dermatitis: 52-week outcomes from the phase 3 AD Up study

Purpose: Atopic dermatitis (AD) adversely impacts quality of life (QoL). We evaluated the effect of upadacitinib, an oral selective Janus kinase inhibitor approved for moderate-to-severe AD, plus topical corticosteroids (+TCS) on patient-reported outcomes (PROs) over 52 weeks. Materials and methods: In the phase 3 AD Up study (NCT03568318), adults and adolescents with moderate-to-severe AD were randomized 1:1:1 to once-daily upadacitinib 15 mg, 30 mg, or placebo + TCS. Itch, skin pain/symptoms, sleep, QoL, daily activities, emotional state, mental health, and patient impressions of disease severity/improvement/treatment satisfaction were assessed. Results: This analysis included 901 patients. Within 1–2 weeks, PRO improvements were greater with both upadacitinib doses than with placebo (p <.05). Improvements increased through weeks 4–8; rates were generally maintained through week 52. At week 52, the proportion of patients with clinically meaningful improvements in itch (Worst Pruritus Numerical Rating Scale improvement ≥4), skin pain (AD Symptom Scale Skin Pain improvement ≥4), sleep (AD Impact Scale [ADerm-IS] Sleep improvement ≥12), daily activities (ADerm-IS Daily Activities improvement ≥14), and emotional state (ADerm-IS Emotional State improvement ≥11) ranged from 62.1%–77.7% with upadacitinib 15 mg + TCS and 71.3%–83.6% with upadacitinib 30 mg + TCS. Conclusions: Upadacitinib + TCS results in rapid, sustained improvements in burdensome AD symptoms and QoL.

Upadacitinib Rapidly Improves Patient-Reported Outcomes in Atopic Dermatitis: 16-Week Results from Phase3 Clinical Trials (Measure Up1 and 2).

Atopic dermatitis (AD) is characterized by intense itch and other symptoms that negatively impact quality of life (QoL). This study evaluates the effect of upadacitinib (an oral selective Janus kinase inhibitor) monotherapy on patient-reported outcomes (PROs) among adults and adolescents with moderate-to-severe AD over 16weeks. This integrated analysis of the double-blind, placebo-controlled periods of phase3 monotherapy clinical trials Measure Up1 (NCT03569293) and Measure Up2 (NCT03607422) assessed itch (Worst Pruritus Numerical Rating Scale [WP-NRS] and SCORing Atopic Dermatitis [SCORAD]), skin pain and symptom severity (AD Symptom Scale), symptom frequency (Patient-Oriented Eczema Measure), sleep (AD Impact Scale [ADerm-IS] and SCORAD), daily activities and emotional state (ADerm-IS), QoL (Dermatology Life Quality Index [DLQI] and Children's DLQI), mental health (Hospital Anxiety and Depression Scale), and patient impressions (Patient Global Impression of Severity, Patient Global Impression of Change, and Patient Global Impression of Treatment). Data from 1683 patients (upadacitinib 15mg, n = 557; upadacitinib 30mg, n = 567; placebo, n = 559) were analyzed. A greater proportion of patients receiving upadacitinib versus placebo experienced improvements in itch (≥ 4-point improvement on WP-NRS) by week1 (upadacitinib 15mg, 11.2%; upadacitinib 30mg, 17.7%; placebo, 0.5%; P < 0.001), with response rates sustained through week16 (upadacitinib 15mg, 47.1%; upadacitinib 30mg, 59.8%; placebo, 10.4%; P < 0.001). Improvements were similar for PROs assessing skin pain/symptoms, sleep, daily activities, QoL, emotional state, mental health, and patient impressions of disease severity and treatment. Responses generally improved rapidly (within 1-2weeks), increased through weeks 4-6, and were maintained through week16. Once-daily oral upadacitinib monotherapy improved response rates across PROs compared with placebo. Upadacitinib therapy resulted in rapid, sustained improvements in PROs measuring symptom burden and QoL in adults and adolescents with moderate-to-severeAD.

Lebrikizumab monotherapy impacts on quality of life scores through improved itch and sleep interference in two Phase 3 trials

Background Lebrikizumab improved itch, interference of itch on sleep, and quality of life (QoL) in patients with moderate-to-severe atopic dermatitis (AD), in two Phase 3 trials at 16 weeks compared to placebo. Objectives We assess improvements in itch and sleep interference due to itch and their impact on QoL measurements after treatment. Methods Data were analyzed from ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967) in patients with moderate-to-severe AD. QoL was evaluated using Dermatology Life Quality Index (DLQI) at Week 16 in patients (>16 years of age) who were itch responders/non-responders (defined as ≥4-point improvement in Pruritus Numeric Rating Scale) or Sleep-Loss Scale responders/non-responders (defined as ≥2-point improvement in itch interference on sleep). Results In ADvocate1 and ADvocate2, significantly greater proportions of itch responders had a clinically meaningful improvement in measures related to QoL (DLQI scores (0/1), ≤5 DLQI total score and ≥4-point DLQI improvement) compared to itch non-responders. In both studies, a significantly greater proportion of Sleep-Loss Scale responders, reported a DLQI score of (0/1), DLQI total score of ≤5 and DLQI improvement of ≥4 points compared to Sleep-Loss Scale non-responders. Conclusions Improvement in itch and sleep interference due to itch is associated with improvement in the QoL of patients after treatment with lebrikizumab for moderate-to-severe AD. ClinicalTrials.gov registration NCT04146363 (ADvocate1) and NCT04178967 (ADvocate2).

Dupilumab improves pruritus and skin lesions in patients with prurigo nodularis: Pooled results from 2 phase 3 trials (LIBERTY-PN PRIME and PRIME2)

Phase 3 PRIME/PRIME2 trials independently demonstrated efficacy and an acceptable safety profile of dupilumab adults with moderate-to-severe prurigo nodularis. To obtain a more precise estimate of onset and magnitude of treatment effect using PRIME/PRIME2 pooled data. In PRIME/PRIME2, patients were randomized to dupilumab or placebo for 24weeks. Pooled analysis assessed proportion of patients achieving clinically meaningful improvement in itch, clear/almost-clear skin, or both; at weeks 12 and 24; overall and by demographic subgroups and changes from baseline to week 24 in symptoms, signs, and quality of life. Patients receiving dupilumab (n=153) vs placebo (n=158) experienced significant improvements in all tested endpoints. At week 24, 90 (58.8%) dupilumab-treated vs 30 (19.0%) placebo-treated patients achieved clinically meaningful improvement in itch, 71 (46.4%) vs 27 (17.1%) clear/almost clear skin, and 54(35.3%) vs 14 (8.9%) achieved both (P<.0001 for all). Treatment benefits were independent of baseline demographics. Safety to week 36 was generally consistent with the known dupilumab safety profile. On-treatment data limited to 24weeks. Pooled analysis confirmed improvements reported in individual trials and revealed earlier effect onset in itch and skin pain. Dupilumab treatment showed benefits across demographics.

Early and Sustained Improvements in Symptoms and Quality of Life with Upadacitinib in Adults and Adolescents with Moderate-to-Severe Atopic Dermatitis: 52-Week Results from Two Phase III Randomized Clinical Trials (Measure Up 1 and MeasureUp2).

Atopic dermatitis is a chronic inflammatory disease characterized by increased itch, skin pain, poor sleep quality, and other symptoms that negatively affect patient quality of life. Upadacitinib, an oral selective Janus kinase (JAK) inhibitor with greater inhibitory potency for JAK1 than JAK2, JAK3, or tyrosine kinase 2, is approved to treat moderate-to-severe atopic dermatitis. We aimed to evaluate the effect of upadacitinib on patient-reported outcomes over 52weeks in adults and adolescents with moderate-to-severe atopic dermatitis. Data from two phase III monotherapy trials of upadacitinib (Measure Up 1, NCT03569293; Measure Up 2, NCT03607422) were integrated. Changes in pruritus, pain, other skin symptoms, sleep, quality of life, mental health, and patient impression were evaluated. Patient-reported outcome assessments included the Worst Pruritus Numerical Rating Scale, Patient-Oriented Eczema Measure, Dermatology Life Quality Index, Atopic Dermatitis Symptom Scale, Atopic Dermatitis Impact Scale, Hospital Anxiety and Depression Scale, SCORing Atopic Dermatitis index, Patient Global Impression of Severity, Patient Global Impression of Change, and Patient Global Impression of Treatment. Minimal clinically important differences, achievement of scores representing minimal disease burden, and the change from baseline were evaluated in patients who received upadacitinib through week 52 and in patients who received placebo through week16. This analysis included 1609 patients (upadacitinib 15 mg, N=557; upadacitinib 30 mg, N=567; placebo, N=485). Baseline demographics and disease characteristics were generally similar across all arms. The proportion of patients treated with upadacitinib reporting improvements in itch increased rapidly by week 1, increased steadily through week 8, and was sustained through week 52. Patients receiving upadacitinib also experienced improvements in pain and other skin symptoms by week 1, which continued through week 16; improvements were maintained through week 52. Patient reports of improved sleep increased rapidly from baseline to week 1, increased steadily through week 32, and were sustained through week 52. Patients experienced quality-of-life improvements through week 8, which were maintained through week 52. By week 1, patients in both upadacitinib groups experienced rapid improvements in emotional state, and by week 12, patients also achieved meaningful improvements in anxiety and depression. Improvements in mental health continued steadily through week 32 and were maintained through week 52. Patients treated with upadacitinib30mg generally experienced improvements in patient-reported outcomes earlier than those treated with upadacitinib 15 mg. Through week 16, patients receiving upadacitinib experienced greater improvements versus those receiving placebo in all assessed patient-reported outcomes. Adults and adolescents with moderate-to-severe atopic dermatitis treated with once-daily upadacitinib 15 or 30 mg experienced early improvements in itch, pain, other skin symptoms, sleep, quality of life, and mental health that were sustained through week52.

Deucravacitinib, an Oral, Selective, Allosteric Tyrosine Kinase 2 Inhibitor, in the Phase 3 Clinical Trials in Psoriasis, POETYK PSO-1 and PSO-2: Time to Meaningful Improvements in Itch as Assessed by the Psoriasis Symptoms and Signs Diary

Introduction: In the phase 3 POETYK PSO-1 and PSO-2 trials in psoriasis, patients completed the Psoriasis Symptoms and Signs Diary (PSSD) daily, recording the average severity of psoriasis symptoms and signs, including itch, over the past 24 hours. Patients receiving deucravacitinib experienced greater improvement in PSSD scores than patients receiving placebo or apremilast, as previously reported. In this analysis, we evaluate the time to improvement in itch in patients treated with deucravacitinib vs placebo in both POETYK trials. Methods: In each trial, adults with moderate to severe plaque psoriasis were randomized 1:2:1 to placebo, deucravacitinib 6 mg once daily, and apremilast 30 mg twice daily; at Week 16, patients receiving placebo crossed over to receive deucravacitinib. Adjusted mean score change from baseline for the PSSD itch item was modeled for deucravacitinib vs placebo using an analysis of covariance model with factors for geographic region, body weight, and prior biologic use, and the baseline value as a covariate. Improvements of ≥2 points on individual PSSD items have been established earlier as meaningful to patients. Time to ≥2-, ≥3-, and ≥4-point improvements from baseline to Week 16 on the PSSD itch item was estimated with Kaplan-Meier methods. Cox models estimated hazard ratios (HRs) for these improvements. Missing data for each analysis were imputed using modified baseline observation carried forward methods. Results: In each trial, significantly greater improvement from baseline in itch score was observed within 2 weeks with deucravacitinib vs placebo. Across both trials, the median (95% confidence interval [CI]) time to ≥2-point and ≥3-point improvements was 6.0 (5.0– 7.0) and 9.0 (8.0–11.0) weeks, respectively, for patients receiving deucravacitinib and not reached for patients receiving placebo (censored at Week 16). Patients receiving deucravacitinib were 3 times more likely to achieve a ≥2-point meaningful improvement in itch score than patients receiving placebo (HR [95% CI]: 3.0 [2.1–4.1] and 3.4 [2.6–4.5] in POETYK PSO-1 and PSO-2, respectively). HRs in favor of deucravacitinib increased as the threshold for improvement increased: at ≥3 points, HRs (95% CI) were 4.0 (2.6–6.1) and 4.9 (3.4–6.9), and at ≥4 points, HRs (95% CI) were 6.5 (3.4–12.4) and 8.8 (5.1–15.2), in POETYK PSO-1 and PSO-2, respectively. Conclusion: Patients receiving deucravacitinib vs placebo experienced improvement in their itch within 2 weeks of treatment. About half of patients receiving deucravacitinib experienced meaningful improvement in itch within 6 weeks. Sponsored by: Bristol Myers Squibb.

Topical ruxolitinib 1.5% (JAK1/JAK2 inhibitor) improves clinical and patient‐reported outcomes in moderate to severe chronic hand dermatitis: Data from a small open‐label trial

AbstractBackgroundChronic hand dermatitis (CHD) has suboptimal treatments and a negative impact on quality of life (QoL). Topical ruxolitinib, a JAK1/JAK2 inhibitor, is approved for vitiligo and mild‐to‐moderate atopic dermatitis, but has not previously been studied specifically for CHD.ObjectivesEvaluate the impact of ruxolitinib in CHD.MethodsA 12‐week, investigator‐initiated, open‐label trial evaluated ruxolitinib 1.5% in 15 adults with recalcitrant moderate‐to‐severe CHD. Primary outcomes included the proportion of patients: (1) achieving an Investigator Global Assessment (IGA) treatment success (0 or 1 score with a two‐step improvement) (2) a Hand Eczema Severity Index (HECSI)‐75 improvement at 12 weeks. Additional outcomes: clinical improvement at 4 and 8 weeks, improvement in itch (Numerical Rating Scale [NRS]) and QoL outcomes (i.e., Dermatology Life Quality Index [DLQI] and Skindex‐Mini).ResultsAt 12 weeks, 13/15 participants (86%) achieved a HECSI‐75, 12/15 participants (80%) had a two‐point reduction in IGA and 8/15 participants (53%) achieved an IGA treatment success. Both atopic dermatitis (AD; n = 7) and non‐AD (n = 8) CHD participants had clinical improvement in HECSI at 12 weeks (p &lt; 0.01). 10/12 participants with baseline NRS ≥ 2 (83%) achieved a ≥ 2 point reduction on average itch at 12 weeks. 9/10 with baseline NRS ≥ 4 (90%) achieved a ≥4‐point itch reduction by 4 and 12 weeks. A significant decline in self‐reported daily itch (average and worst) was observed within the first week of treatment (p &lt; 0.001). By CHD subtype, AD‐CHD had greater itch at baseline compared to non‐AD CHD (p &lt; 0.01), consequently itch reduction was greater in AD‐subtype. Improvement in QoL (DLQI, Skindex‐Mini) was achieved at 4 weeks maintained to 12 weeks (p &lt; 0.01). No treatment‐related adverse events were reported during the study and no rescue medications were used.ConclusionsRuxolitinib may be a promising treatment for CHD, improving clinical outcomes, itch and QoL. Significant improvement was achieved at 4 weeks and maintained through 12 weeks of treatment.

562 - Dupilumab treatment provides long-term improvement in itch in pediatric patients with moderate-to-severe atopic dermatitis over 1 year

Abstract Introduction/Background As symptoms of atopic dermatitis (AD) can wax and wane over time, disease control is better represented by consistency of response over a long treatment duration rather than at a single time point. Objective To evaluate the proportion of pediatric patients achieving and maintaining mild or no itch (defined by a SCORing Atopic Dermatitis (SCORAD) itch visual analog scale (VAS; 0-10 over last 3 days) score of lower than 4) across 5 visits during a 52-week open label extension trial of dupilumab. Methods Patients who previously participated in 16-week trials and were aged 0.5–5 years (LIBERTY AD PRESCHOOL; NCT03346434), 6–11 years (LIBERTY AD PEDs; NCT03345914), and 12–17 years (LIBERTY AD ADOL; NCT03054428), were subsequently enrolled in the phase 3, open-label extension trial, LIBERTY AD PED-OLE (NCT02612454). Patients were treated with 300 mg q4w or 200/300 mg q2w (body weight &amp;lt;60 or ≥60 kg, respectively). In this analysis, patients with a SCORAD itch VAS score of greater than 4 at OLE baseline, were assessed for the maintenance of SCORAD itch VAS lower than 4, at 5 timepoints: Weeks 4, 16, 28, 40, and 52. Results In 763 patients, 400 patients with a SCORAD itch VAS score of greater than 4 were assessed. Mild or no itch was achieved in at least 4 of 5 timepoints in most patients aged 0.5–5 years (55/110; 50%), 6–11 years (76/148; 51%), and 12–17 years (73/142; 51%). Across these age groups, over 65% maintained this response for at least 3 of 5 timepoints. Safety was consistent with the known dupilumab safety profile in patients with atopic dermatitis. Conclusions Most pediatric patients achieved improvement in itch, maintained during 1 year of treatment with dupilumab. Results were consistent for infants/preschoolers, children, and adolescents.

497 - Lebrikizumab in combination with topical corticosteroids maintains improvements in itch and sleep at 68 weeks in patients with moderate-to-severe atopic dermatitis

Abstract Introduction/Background Atopic dermatitis (AD) is a chronic disease affecting children and adults and requires long-term treatment. Moderate-to-severe AD causes itching, which considerably impacts sleep. Interleukin (IL)-13 is the key cytokine in the skin of patients with AD. Lebrikizumab (LEB) is a novel monoclonal antibody that binds with high affinity and slow off-rate to IL-13, thereby blocking the downstream effects of IL-13 with high potency. LEB has demonstrated efficacy and maintained improvement in measures of itch and sleep over 52 weeks in previous phase 3 trials. ADhere (NCT04250337) was a 16-week, randomized, double-blinded, placebo-controlled, phase 3 clinical trial, where patients were treated with LEB and topical corticosteroids (TCS) vs placebo and TCS. LEB responders from ADhere at week 16 were defined as having Investigator’s Global Assessment response of 0 or 1 or reporting 75% improvement from ADhere baseline in Eczema Area and Severity Index who did not use rescue medications. ADhere LEB responders were rerandomized 2:1 into ADjoin (NCT04392154) for blinded treatment with LEB 250 mg every 2 weeks (Q2W) or every 4 weeks (Q4W), respectively, with TCS use as needed, for an additional 100 weeks with itch and sleep data being collected for the first 52 weeks. Objectives The objectives of the study are to report the impact of LEB on itch and sleep improvements over a longer period (68 weeks) in ADhere week 16 LEB responders with moderate-to-severe AD who entered a long-term extension study, ADjoin. Methods Itch was reported using the Pruritus Numeric Rating Scale (NRS), a patient-reported, single-item, daily, 11-point scale, where the minimal clinically important difference (MCID) is 3 points. Sleep loss due to itch was reported using the Sleep-Loss Scale, a patient-reported, single-item, 5-point scale, where the MCID is 1 point. We report ≥3-point improvement in Pruritus NRS among patients with baseline score at least 3, percent change from ADhere baseline (PCFB) in Pruritus NRS, Pruritus NRS (0,1), ≥1-point improvement in Sleep-Loss Scale score among patients with baseline score at least 1, ≥2-point improvement in Sleep-Loss Scale score among patients with baseline score at least 2 and PCFB in Sleep-Loss Scale score. All outcomes were reported at week 52 of ADjoin study, after a total of 68 weeks of LEB treatment. As observed analyses used all data collected. Results At week 68, most patients reported maintaining ≥3-point improvement in Pruritus NRS treated with LEB Q2W (80.6%, 29/36) and LEB Q4W (88.9%, 16/18). Patients treated with LEB Q2W and LEB Q4W reported maintaining 65.3% and 59.4% improvement in Pruritus NRS at week 68 compared to ADhere baseline, respectively. At week 68, 45.9% (17/37) patients in LEB Q2W group and 31.6% (6/19) in LEB Q4W group reached Pruritus NRS of 0 or 1. At week 68, most patients reported maintaining ≥1-point improvement in Sleep-Loss Scale score treated with LEB Q2W (96.9%, 31/32) and LEB Q4W (85.7%, 12/14). Similarly, most patients reported maintaining ≥2-point improvement in Sleep-Loss Scale score treated with LEB Q2W (60.9%, 14/23) and LEB Q4W (75.0%, 6/8). Patients treated with LEB Q2W and Q4W reported maintaining 84.1% and 58.8% improvement in Sleep-Loss Scale score at week 68, respectively, compared to ADhere baseline. Conclusions LEB + TCS maintained itch and sleep improvement at 68 weeks in patients with moderate-to-severe atopic dermatitis.

515 - Rapid and early onset of itch relief with tapinarof cream 1% once daily in two pivotal phase 3 trials in adults and children down to two years of age with atopic dermatitis

Abstract Introduction Itch is the most bothersome symptom for patients with atopic dermatitis (AD), with a significant negative impact on health-related quality of life. Rapid onset of pruritus relief with sustained efficacy is a key outcome for AD therapies. In a phase 2 trial in adults and adolescents with moderate to severe AD, tapinarof cream 1% once daily (QD) demonstrated efficacy versus vehicle and was well tolerated. Objective Here, we evaluate time to onset of itch relief in the pivotal phase 3 trials with tapinarof cream 1% QD in the treatment of adults and children down to 2 years of age with AD. Materials and Methods In ADORING 1 and 2, two identical, double-blind, vehicle-controlled trials, patients were randomized 2:1 to tapinarof cream 1% or vehicle QD for 8 weeks. Patients with a Validated Investigator Global Assessment for Atopic DermatitisTM score of ≥3, an Eczema Area and Severity Index score of ≥6, and body surface area involvement of 5–35% were included. Efficacy endpoints that evaluated itch relief were mean changes in Peak Pruritus-Numerical Rating Scale (PP-NRS) score (daily and by visit [Weeks 1, 2, 4, and 8]) from baseline through Week 8. The PP-NRS considers a person’s worst itch over the past 24 hours, assessed on an 11-point scale (0 indicates “no itch” and 10 is “worst imaginable itch”). Daily PP-NRS scores were recorded in diaries. Patients aged ≥12 years self-completed the PP-NRS, while caregivers completed it for children aged &amp;lt;12 years. Results 407 and 406 patients were randomized in ADORING 1 and 2. At baseline, mean (standard deviation [SD]) PP-NRS scores were 6.7 (2.4) and 6.8 (2.3) in both trials, respectively. For daily evaluations of itch from baseline, greater reductions in PP-NRS scores (mean [SD]) for tapinarof versus vehicle were observed as early as Day 1, 24 hours after initial application, in ADORING 1 (–1.2 [2.2] vs –0.9 [2.0]) and Day 2 in ADORING 2 (–1.6 [2.4] vs –1.4 [2.1]). Improvements in daily PP-NRS scores (mean [SD]) with tapinarof versus vehicle continued through the first 2 weeks (Day 14; –3.0 [2.8] vs –2.0 [2.4] and –2.9 [2.7] vs –1.8 [2.6]), and through Week 8 of both trials. There were statistically significant and clinically meaningful reductions in mean weekly PP-NRS scores as early as Week 1, the first assessment, for patients treated with tapinarof compared with vehicle (–2.0 vs –1.2 [P&amp;lt;0.0001]) and (–2.0 vs –1.3 [P=0.0010]), in ADORING 1 and 2, respectively. Significantly greater reductions in mean PP-NRS scores with tapinarof versus vehicle were seen for all visits through Week 8 (–4.1 vs –2.6 and –4.1 vs –2.4 [both P&amp;lt;0.0001]), for both trials. Conclusions Tapinarof cream 1% QD demonstrated rapid, clinically meaningful, and significant onset of pruritus relief as early as 24 hours after initial application compared with vehicle. Improvements in itch with tapinarof cream increased through Week 8 in both trials in adults and children down to 2 years with AD.

502 - Efficacy and safety of upadacitinib through 140 weeks in adolescents and adults with moderate-to-severe atopic dermatitis: phase 3 randomized clinical trial results

Abstract Introduction &amp; Objectives Upadacitinib (UPA) is an oral Janus kinase 1 (JAK1) inhibitor approved in multiple countries for the treatment of adolescents and adults with moderate-to-severe atopic dermatitis (AD). Here, we present the efficacy and safety of UPA administered over 140 weeks in an ongoing randomized, double-blinded, multicenter phase 3 study (Measure Up 1, NCT03569293). Materials &amp; Methods Patients (12–75 years) with moderate-to-severe AD were randomized 1:1:1 to receive UPA 15 mg (UPA15), UPA 30 mg (UPA30), or placebo (PBO) once daily at baseline. At week 16, PBO-treated patients were re-randomized 1:1 to receive UPA15 (PBO/UPA15) or UPA30 (PBO/UPA30) once daily. Co-primary endpoints were the proportion of patients achieving ≥75% reduction in EASI (EASI 75) from baseline and vIGA-AD of clear (0) or almost clear (1) with ≥2 grades of reduction from baseline (vIGA-AD 0/1) at week 16. A meaningful improvement in itch, defined as a ≥4-point reduction in Worst Pruritus Numeric Rating Scale (ΔWP-NRS≥4), was assessed among patients with baseline WP-NRS≥4. All efficacy endpoints were summarized using the Observed Cases (OC) approach, and no missing data imputation was applied. Safety was assessed by monitoring of serious adverse events (SAEs), treatment-emergent adverse events (TEAEs), and treatment-emergent adverse events of special interest (AESI), which were analysed as exposure-adjusted rates per 100 patient-years (PY). Results Efficacy results were sustained up to week 140 since week 16. Proportions of patients in the UPA15 (205), UPA30 (206), PBO/UPA15 (91), and PBO/UPA30 (94) groups achieving EASI 75 at week 140 were 88.8% (182), 90.3% (186), 83.5% (76), and 89.4% (84), respectively, and for vIGA-AD 0/1 was 63.4% (130), 65.5% (135), 60.4% (55), and 75.5% (71), respectively. Proportions of patients achieving an improvement (reduction) in WP-NRS≥4 from baseline at week 140 were 68.0% (136), 70.5% (146), 71.3% (62), and 81.3% (74) respectively. Overall, the rates of AESIs were similar across treatment groups, which aligned with prior reports at earlier time points. Both UPA15 and UPA30 were well-tolerated in all patients, and no new safety signals were observed compared to the known safety profile of UPA. Data from two additional pivotal studies will be available at the time of presentation. Conclusion In this interim analysis, sustained skin clearance and itch and a consistent safety profile were observed with UPA 15 mg and UPA 30 mg across 140 weeks in adolescent and adult patients with moderate-to-severe AD.

505 - Once-daily roflumilast cream 0.15% for atopic dermatitis: pooled results from INTEGUMENT-1/2 phase 3 trials

Abstract Introduction Roflumilast cream 0.15% is a selective, highly potent phosphodiesterase 4 inhibitor under investigation as a non-steroidal, once-daily treatment for atopic dermatitis (AD). Objectives Here, pooled results from two identical Phase 3 randomized controlled trials (INTEGUMENT-1: NCT04773587 and INTEGUMENT-2: NCT04773600) are presented. Methods Patients with AD aged ≥6 years with baseline Eczema Area and Severity Index (EASI) score ≥5 and Validated Investigator Global Assessment-AD (vIGA-AD) score of Mild or Moderate were randomized 2:1 to apply roflumilast (n=884) or vehicle (n=453) once daily for 4 weeks. Results A significantly greater percentage of roflumilast- versus vehicle-treated patients achieved the primary endpoint, vIGA-AD Success (Clear or Almost Clear vIGA-AD plus ≥2-grade improvement from baseline) at Week 4 (31.3% vs. 14.1%; P&amp;lt;0.0001). Significant differences favoring roflumilast were observed for multiple secondary endpoints at Week 4: percentage of patients achieving vIGA-AD of Clear or Almost Clear (41.1% vs. 21.4%; P&amp;lt;0.0001), percentage achieving 75% reduction in EASI (42.7% vs. 20.6%; P&amp;lt;0.0001), and percentage with baseline Worst Itch-Numeric Rating Scale ≥4 achieving a 4-point reduction (31.9% vs. 16.6%; P&amp;lt;0.0001). Improvement in itch was reported as early as 24 hours. Both groups had low incidences of treatment-emergent adverse events (TEAE), serious adverse events, and TEAEs leading to discontinuation. Local tolerability was favorable, with &amp;gt;90% of patients reporting no or mild sensation across both treatment groups at all timepoints. Conclusions Once-daily roflumilast cream 0.15% provided improvement across multiple efficacy endpoints by Week 4 with favorable safety and tolerability in patients aged ≥6 years with AD in two Phase 3 trials.

Prospective Randomized Double-Blind Vehicle-Controlled Study of Topical Coconut and Sunflower Seed Oil-Derived Isosorbide Diesters on Atopic Dermatitis.

Background: Preliminary studies support the use of topical coconut and sunflower seed oil for atopic dermatitis (AD). However, standardized topical formulations of fatty acids from these sources have not been studied. Objective: This study investigates whether coconut oil- and sunflower seed oil-derived isosorbide diesters can be used in conjunction with colloidal oatmeal to improve itch, AD severity, and the need for topical steroids in adults. Methods: This was a single-center, 4-week, randomized, double-blind, and vehicle-controlled study conducted between 2021 and 2022. Thirty-two male and female adults with mild-to-moderate AD were enrolled and completed the study. Participants were randomized to receive either 0.1% colloidal oatmeal (vehicle) or isosorbide diesters (IDEAS, 4% isosorbide dicaprylate and 4% isosorbide disunflowerseedate) along with 0.1% colloidal oatmeal. The main outcomes of the study were changes in the visual analogue rating of itch and 75% improvement in the Eczema Area and Severity Index score (EASI 75) at 4 weeks. Other measures included the use of topical steroids and the relative abundance of skin Staphylococcus aureus. Results: Participants in the IDEAS group had a 65.6% improvement in itch compared with 43.8% in the vehicle group (P = 0.013). In total, 56.5% and 25% of the those in the IDEAS and vehicle groups, respectively, achieved EASI 75 at 4 weeks (P = 0.07). There was no difference in skin hydration or transepidermal water loss. The relative abundance of S. aureus was decreased in the IDEAS group at week 4 compared with no change in the vehicle group (P = 0.044). Topical corticosteroid use increased in the vehicle group compared with a decrease in the IDEAS group at week 1 (292.5% vs 24.8%; P value = 0.039) and week 2 (220% vs 46%; P value = 0.08). Conclusions: Topical application of emollients containing coconut oil- and sunflower seed oil-derived fatty esters may improve itch, reduce topical steroid use, and reduce the relative abundance of S. aureus in mild-to-moderate AD. CTR number: NCT04831892.
