Efficacy, Safety, and Long-Term Disease Control of Ruxolitinib Cream Among Adolescents with Atopic Dermatitis: Pooled Results from Two Randomized Phase 3 Studies.

BACKGROUND: Atopic dermatitis (AD), a highly pruritic, inflammatory skin disease, affects approximately 7% of adolescents globally. A topical formulation of ruxolitinib, a Janus kinase (JAK) 1/JAK2 inhibitor, demonstrated safety and efficacy among adolescents/adults in two phase 3 studies (TRuE-AD1/TRuE-AD2). OBJECTIVE: To describe safety and efficacy of 1.5% ruxolitinib cream versus vehicle and long-term disease control of ruxolitinib cream among adolescents aged 12-17 years from pooled phase 3 study data. METHODS: Patients [≥ 12 years old with AD for ≥ 2 years, Investigator's Global Assessment score (IGA) 2/3, and 3-20% affected body surface area (BSA) at baseline] were randomized 2:2:1 to ruxolitinib cream (0.75%/1.5%) or vehicle for 8 weeks of continuous use followed by a long-term safety (LTS) period up to 52 weeks with as-needed use. Patients originally applying vehicle were rerandomized 1:1 to 0.75%/1.5% ruxolitinib cream. Efficacy measures at week 8 included IGA treatment success (IGA-TS; i.e., score of 0/1 with ≥ 2 grade improvement from baseline), ≥ 75% improvement in Eczema Area and Severity Index (EASI-75), and ≥ 4-point improvement in itch numerical rating scale (NRS4). Measures of disease control during the LTS period included IGA score of 0 (clear) or 1 (almost clear) and percentage affected BSA. Safety was assessed throughout the study. RESULTS: Of 1249 randomized patients, 245 (19.6%) were aged 12-17 years. Of these, 45 patients were randomized to vehicle and 92 patients to 1.5% ruxolitinib cream. A total of 104/137 (75.9%) patients continued on 1.5% ruxolitinib cream in the LTS period [82/92 (89.1%) continued on 1.5% ruxolitinib cream; 22/45 (48.9%) patients on vehicle were reassigned to 1.5% ruxolitinib cream], and 83/104 (79.8%) of these patients completed the LTS period. At week 8, substantially more patients who applied 1.5% ruxolitinib cream versus vehicle achieved IGA-TS (50.6% versus 14.0%), EASI-75 (60.9% versus 34.9%), and NRS4 (52.1% versus 17.4%; P = 0.009). The mean (SD) reduction in itch NRS scores was significantly greater in patients applying 1.5% ruxolitinib cream versus vehicle from day 2 [- 0.9 (1.9) versus -0.2 (1.4); P = 0.03]. During the LTS period, mean (SD) trough steady-state ruxolitinib plasma concentrations at weeks 12/52 were 27.2 (55.7)/15.5 (31.5) nM. The percentage of patients achieving IGA score of 0 or 1 was sustained or further increased with 1.5% ruxolitinib cream; mean affected BSA was generally low (< 3%; i.e., mild disease). Through 52 weeks, application site reactions occurred in 1.8% of adolescent patients applying 1.5% ruxolitinib cream at any time; no patients had serious adverse events. There were no serious infections, malignancies, major adverse cardiovascular events, or thromboembolic events. CONCLUSIONS: Meaningful anti-inflammatory and antipruritic effects were demonstrated with 1.5% ruxolitinib cream in the subset of adolescent patients with AD, comparable with those observed in the overall study population; long-term, as-needed use maintained disease control and was well tolerated.

Lebrikizumab Provides Rapid Clinical Responses Across All Eczema Area and Severity Index Body Regions and Clinical Signs in Adolescents and Adults with Moderate-to-Severe Atopic Dermatitis.

INTRODUCTION: Atopic dermatitis (AD) affects multiple areas of the body, some of which may be more refractory to treatment. We evaluated improvements in the Eczema Area and Severity Index (EASI) by body region and clinical signs for each body region in lebrikizumab-treated patients with moderate-to-severe AD. METHODS: ADvocate 1 and ADvocate 2 compared lebrikizumab 250 mg as monotherapy every 2 weeks versus placebo for 16 weeks. Efficacy measures included EASI, which rates the extent and severity of four clinical signs (erythema, edema/papulation, excoriation, lichenification) in four body regions (head/neck, upper extremities, trunk, lower extremities). Analyses are post hoc. RESULTS: Mean baseline EASI, body region EASI subscores, and the severity of clinical signs were consistent across both studies (EASI ranging from 16.0 to 72.0). At week 16 in both studies, patients treated with lebrikizumab showed significantly greater percent improvement in EASI across all body regions versus placebo (p ≤ 0.001), with improvements as early as week 2. In ADvocate 1, all clinical signs significantly improved across all body regions at week 16 with lebrikizumab (51.4-71.6% improvement) versus placebo (23.1-43.5%, p ≤ 0.001), with significant improvements as early as week 2 for all signs. Significant improvements for all clinical signs at week 16 were also seen in ADvocate 2 for lebrikizumab (53.5-75.6%) versus placebo (28.5-41.2%, p ≤ 0.001) and as early as week 2 for all body regions and signs except head/neck erythema and lower extremity erythema, edema/papulation, and lichenification, which showed significant improvement by week 4. CONCLUSIONS: Lebrikizumab as monotherapy consistently and rapidly reduced the extent of involvement and severity of AD in all EASI clinical signs and body regions, including the head and neck region and clinical sign of lichenification, compared with placebo. TRIAL REGISTRATION: ClinicalTrials.gov identifier: ADvocate 1 (NCT04146363) and ADvocate 2 (NCT04178967).

Targeting IL-13 with tralokinumab normalizes type 2 inflammation in atopic dermatitis both early and at 2 years.

BACKGROUND: Tralokinumab is a monoclonal antibody that specifically neutralizes interleukin (IL)-13, a key driver of skin inflammation and barrier abnormalities in atopic dermatitis (AD). This study evaluated early and 2-year impacts of IL-13 neutralization on skin and serum biomarkers following tralokinumab treatment in adults with moderate-to-severe AD. METHODS: Skin biopsies and blood samples were evaluated from a subset of patients enrolled in the Phase 3 ECZTRA 1 (NCT03131648) and the long-term extension ECZTEND (NCT03587805) trials. Gene expression was assessed by RNA sequencing; protein expression was assessed by immunohistochemistry and immunoassay. RESULTS: Tralokinumab improved the transcriptomic profile of lesional skin by Week 4. Mean improvements in the expression of genes dysregulated in AD were 39% at Week 16 and 85% at 2 years with tralokinumab, with 15% worsening at Week 16 with placebo. At Week 16, tralokinumab significantly decreased type 2 serum biomarkers (CCL17/TARC, periostin, and IgE), reduced epidermal thickness versus placebo, and increased loricrin coverage versus baseline. Two years of tralokinumab treatment significantly reduced expression of genes in the Th2 (IL4R, IL31, CCL17, and CCL26), Th1 (IFNG), and Th17/Th22 (IL22, S100A7, S100A8, and S100A9) pathways as well as increased expression of epidermal differentiation and barrier genes (CLDN1 and LOR). Tralokinumab also shifted atherosclerosis signaling pathway genes (SELE, IL-37, and S100A8) toward non-lesional expression. CONCLUSION: Tralokinumab treatment improved epidermal pathology, reduced systemic markers of type 2 inflammation, and shifted expression of key AD biomarkers in skin towards non-lesional levels, further highlighting the key role of IL-13 in the pathogenesis of AD.

Mental health outcomes in patients with moderate to severe psoriasis treated with bimekizumab: Analysis of phase 2/3 randomized trials.

BACKGROUND: Patients with psoriasis have increased risk of suicidal ideation and behavior (SIB) and depression. Bimekizumab, a biologic that inhibits interleukin (IL)-17A and IL-17F, received Food and Drug Administration approval in 2023 for moderate to severe plaque psoriasis, following 2021 European Medicines Agency approval. OBJECTIVE: To report SIB and depression in patients with moderate to severe psoriasis treated in bimekizumab clinical trials. METHODS: Mental health changes, including neuropsychiatric events, were actively monitored across 9 bimekizumab clinical trials in psoriasis phase 2/3 trials. The patient-reported electronic Columbia-Suicide Severity Rating Scale (measuring SIB) and Patient Health Questionnaire-9 (measuring depression) were administered, monitored by an independent Neuropsychiatric Adjudication Committee. RESULTS: Throughout 7166 patient-years (PY) of bimekizumab exposure, the adjudicated SIB rate was 0.13/100PY; SIB ranges for the general psoriasis population and patients receiving anti-IL-17A/anti-IL-23 therapies are 0.09 to 0.54/100PY and 0.09 to 0.19/100PY, respectively. At week 16, 92.9% vs 81.1% of bimekizumab- vs placebo-treated patients had no/minimal depression. Newonset positive electronic Columbia-Suicide Severity Rating Scale responses and mean Patient Health Questionnaire-9 scores were low for bimekizumab-treated patients. LIMITATIONS: Patient exclusion for significant/severe prespecified SIB/depression history. CONCLUSION: The long-term adjudicated SIB rate with bimekizumab was low and within ranges reported in the general psoriasis patient population and psoriasis patients treated with anti-IL-17A/anti-IL-23 biologics. Screening/monitoring questionnaires reported low SIB and depression levels.

Comparing Achievement of National Psoriasis Foundation Treatment Targets among Patients with Plaque Psoriasis Treated with Ixekizumab versus Other Biologics in Clinical and Real-World Studies.

INTRODUCTION: The National Psoriasis Foundation (NPF) recommends evaluating patient response to treatment at week 12, with a target response of ≤ 1% body surface area (BSA) affected by plaque psoriasis and an acceptable response of BSA ≤ 3% or ≥ 75% improvement. This post hoc analysis compared the achievement of NPF target and acceptable responses for ixekizumab (IXE) versus other biologics. METHODS: Outcomes were evaluated at week 12 for patients with moderate-to-severe plaque psoriasis from four head-to-head randomized clinical trials (RCTs; UNCOVER-2, UNCOVER-3, IXORA-R, and IXORA-S) and one real-world prospective observational study (Psoriasis Study of Health Outcomes; PSoHO). RCT patients were treated with IXE or etanercept (ETN; UNCOVER-2/3), guselkumab (GUS; IXORA-R), or ustekinumab (UST; IXORA-S). PSoHO patients were treated with anti-interleukin (IL)-17A biologics (IXE, secukinumab, SEC) and other approved biologics for the treatment of plaque psoriasis. Patients with missing outcomes were imputed as non-responder imputation. For RCT data, statistical comparisons between treatment groups were performed using Fisher's exact test with no multiplicity adjustments. For real-world data, adjusted comparative analyses were performed using frequentist model averaging (FMA) and reported as odds ratio (OR). RESULTS: Across the four head-to-head clinical trials analyzed, significantly higher proportions of patients achieved target and acceptable responses at week 12 with IXE versus ETN, GUS, or UST. Likewise, the proportion of PSoHO patients achieving target and acceptable response at week 12 was higher with IXE compared with other individual biologics. Adjusted comparative analyses showed that IXE had significantly greater odds of target and acceptable response at week 12 versus SEC, GUS, risankizumab (RIS), adalimumab (ADA), UST, and tildrakizumab (TILD) and numerically greater odds of target and acceptable response at week 12 versus brodalumab (BROD). CONCLUSION: Across both clinical studies and real-world settings, more patients treated with IXE achieved NPF target and acceptable responses at week 12 compared with those treated with other biologics. TRIAL REGISTRATION: UNCOVER-2 (NCT01597245); UNCOVER-3 (NCT01646177); IXORA-R (NCT03573323); IXORA-S (NCT02561806); PSoHO (EUPAS24207).

Deucravacitinib in moderate-to-severe plaque psoriasis: Pooled safety and tolerability over 52 weeks from two phase 3 trials (POETYK PSO-1 and PSO-2).

BACKGROUND: Two phase 3 trials, POETYK PSO-1 and PSO-2, previously established the efficacy and overall safety of deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 (TYK2) inhibitor, in plaque psoriasis. OBJECTIVES: To further assess the safety of deucravacitinib over 52 weeks in the pooled population from these two trials. METHODS: Pooled safety data were evaluated from PSO-1 and PSO-2 in which patients with moderate-to-severe plaque psoriasis were randomized 1:2:1 to receive oral placebo, deucravacitinib or apremilast. RESULTS: A total of 1683 patients were included in the pooled analysis. Adverse event (AE) incidence rates were similar in each treatment group, serious AEs were low and balanced across groups, and discontinuation rates were lower with deucravacitinib versus placebo or apremilast. No new safety signals emerged with longer deucravacitinib treatment. Exposure-adjusted incidence rates of AEs of interest with placebo, deucravacitinib and apremilast, respectively, were as follows: serious infections (0.8/100 person-years [PY], 1.7/100 PY, and 1.8/100 PY), major adverse cardiovascular events (1.2/100 PY, 0.3/100 PY, and 0.9/100 PY), venous thromboembolic events (0, 0.2/100 PY, and 0), malignancies (0, 1.0/100 PY and 0.9/100 PY), herpes zoster (0.4/100 PY, 0.8/100 PY, and 0), acne (0.4/100 PY, 2.9/100 PY, and 0) and folliculitis (0, 2.8/100 PY, and 0.9/100 PY). No clinically meaningful changes from baseline in mean levels, or shifts from baseline to CTCAE grade ≥3 abnormalities, were reported in laboratory parameters with deucravacitinib. CONCLUSIONS: Deucravacitinib was well-tolerated with acceptable safety over 52 weeks in patients with psoriasis.

Long-term safety of Ixekizumab in adults with psoriasis, psoriatic arthritis, or axial spondyloarthritis: a post-hoc analysis of final safety data from 25 randomized clinical trials.

BACKGROUND: We report long-term, end-of-study program safety outcomes from 25 randomized clinical trials (RCTs) in adult patients with psoriasis (PsO), psoriatic arthritis (PsA), or axial spondyloarthritis (axSpA) [including ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA)] who received ≥ 1 dose of Ixekizumab (IXE) over 5 years (PsO) or up to 3 years (PsA, axSpA). METHODS: This integrated safety analysis consists of data from patients who received any dose of IXE, across 25 RCTs (17 PsO, 4 PsA, 4 axSpA). Rates of treatment-emergent adverse events (TEAEs), serious adverse events (SAEs) and selected adverse events (AEs) of interest were analyzed for all pooled studies by years of therapy and overall, through March 2022. Results were reported as exposure-adjusted incidence rates (IRs) per 100 patient-years (PY) overall and at successive year intervals. RESULTS: Six thousand eight hundred ninety two adult patients with PsO, 1401 with PsA, and 932 with axSpA (including AS and nr-axSpA), with a cumulative IXE exposure of 22,371.1 PY were included. The most commonly reported TEAE across indications was nasopharyngitis (IRs per 100 PY: 8.8 (PsO), 9.0 (PsA), 8.4 (axSpA)). SAEs were reported by 969 patients with PsO (IR 5.4), 134 patients with PsA (IR 6.0), and 101 patients with axSpA (IR 4.8). Forty-five deaths were reported (PsO, n = 36, IR 0.2; PsA, n = 6, IR 0.3; axSpA, n = 3, IR 0.1). TEAEs did not increase during IXE exposure: IRs per 100 PY, PsO: 88.9 to 63.2 (year 0-1 to 4-5), PsA: 87 to 67.3 (year 0-1 to 2-3), axSpA: 82.1 to 55.4 (year 0-1 to > = 2). IRs per 100 PY of discontinuation from IXE due to AE were 2.9 (PsO), 5.1 (PsA), and 3.1 (axSpA). IRs per 100 PY of injection site reactions were 5.9 (PsO), 11.6 (PsA) and 7.4 (axSpA); Candida: 1.9 (PsO), 2.0 (PsA), and 1.2 (axSpA); depression, major adverse cerebro-cardiovascular events and malignancies: ≤ 1.6 across all indications. Adjudicated IRs per 100 PY of inflammatory bowel disease were ≤ 0.8 across indications (0.1 [PsO]; 0.1 [PsA]; 0.8 [axSpA]). CONCLUSIONS: In this integrated safety analysis, consisting of over 22,000 PY of exposure, the long-term safety profile of IXE was found to be consistent with previous, earlier reports, with no new safety signals identified. TRIAL REGISTRATION: NCT registration numbers for RCTs included in this integrated analysis can be found in Additional File 1.

Deucravacitinib in plaque psoriasis: 2-year safety and efficacy results from the phase III POETYK trials.

BACKGROUND: In the phase III POETYK PSO-1 and PSO-2 trials, deucravacitinib, an oral selective allosteric tyrosine kinase 2 inhibitor, was well tolerated and efficacious over 1 year in patients with psoriasis. OBJECTIVE: To evaluate deucravacitinib safety and efficacy over 2 years in patients participating in the phase III trials. METHODS: In the POETYK long-term extension (LTE), an ongoing phase IIIb open-label trial, adults with moderate-to-severe plaque psoriasis who completed PSO-1 or PSO-2 receive deucravacitinib 6 mg once daily. Safety was assessed via adverse events (AEs) and laboratory parameter abnormalities. Efficacy endpoints, including ≥ 75% reduction from baseline Psoriasis Area and Severity Index score (PASI 75) and static Physician's Global Assessment (sPGA) score of 0/1 (clear/almost clear), were evaluated in patients originally randomized to deucravacitinib, patients who crossed over from placebo at week 16 and patients who achieved PASI 75 at week 24 (peak efficacy). RESULTS: At data cutoff (1 October 2021), 1519 patients had received at least one dose of deucravacitinib; 79.0% and 39.9% had ≥ 52 weeks and ≥ 104 weeks of total deucravacitinib exposure, respectively. Exposure-adjusted incidence rates (EAIRs) per 100 person-years were similar at 1 year and 2 years for any AEs (229.2 vs. 154.4, respectively), serious AEs (5.7 vs. 6.1), discontinuations (4.4 vs. 2.8), deaths (0.2 vs. 0.4), serious infections (1.7 vs. 2.6), herpes zoster (0.9 vs. 0.8), major adverse cardiovascular events (0.3 vs. 0.4), venous thromboembolic events (0.2 vs. 0.1) and malignancies (1.0 vs. 0.9). EAIRs for COVID-19 infections were higher at 2 years than at 1 year (5.1 vs. 0.5) owing to the peak of the global COVID-19 pandemic occurring during the LTE. No clinically meaningful changes from baseline or trends were observed over 2 years in haematological, chemistry or lipid parameters. Clinical responses were maintained in patients who received continuous deu-cravacitinib treatment from baseline [PASI 75: week 52, 72.4%; week 112, 79.7%; sPGA 0/1: week 52, 57.9%; week 112, 61.1% (as observed)]. Responses at week 52 were also maintained in placebo crossovers and in week-24 PASI-75 responders. CONCLUSIONS: Deucravacitinib maintained efficacy and demonstrated consistent safety with no new safety signals observed through 2 years.

Psoriasis is a chronic inflammatory skin condition. Many available treatments for psoriasis are injected, but can be inadequate in terms of effectiveness, and/or cause serious side-effects. Deucravacitinib is a recently approved oral medicine that interferes with an enzyme involved in inflammation called 'tyrosine kinase 2' (TYK2). Deucravacitinib has been shown to improve psoriatic patches and symptoms (such as itching) through 1 year in two global clinical trials in adults with moderate-to-severe plaque psoriasis (POETYK PSO-1 and PSO-2). This study was an analysis of the safety and efficacy of deu­cravacitinib for up to 2 years. To do this, the researchers used data from approximately 1500 people who completed both trials and continued into an ongoing, long-term extension trial (POETYK LTE). Overall, there were no new side-effects, and the number, type and severity of side-effects, as well as the number of patients who stopped treatment because of these side-effects, remained low. The most frequent side-effects included common cold symptoms and COVID-19. Rates of shingles and serious side-effects were comparable to rates reported in the real world. Improvements in psoriasis symptoms seen at 1 year were maintained for up to 2 years in patients receiving deucravacitinib treatment from the start of PSO-1 or PSO-2, or who crossed over from placebo to deucravacitinib at 4 months. Long-term treatment with deucravacitinib improved psoriasis symptoms and resulted in mostly mild side-effects. The study findings suggest that deucravacitinib could be a well-tolerated and effective treatment for people with psoriasis.

Roflumilast foam 0.3% for adolescent and adult patients with seborrheic dermatitis: A randomized, double-blinded, vehicle-controlled, phase 3 trial.

BACKGROUND: The topical phosphodiesterase 4 inhibitor roflumilast has been studied in several dermatologic conditions. OBJECTIVE: Roflumilast foam 0.3% is being investigated as a topical treatment for seborrheic dermatitis (SD). METHODS: In this phase 3, double-blinded trial, patients with SD were randomly assigned (2:1 ratio) to once-daily roflumilast foam 0.3% or vehicle foam for 8 weeks. The primary efficacy outcome was Investigator Global Assessment (IGA) Success at week 8, defined as IGA of 0 (Clear) or 1 (Almost Clear) plus ≥2-point improvement from baseline. Safety was also assessed. RESULTS: 79.5% of roflumilast-treated and 58.0% of vehicle-treated patients met the primary endpoint (P < .001); statistically significant differences in IGA Success also favored roflumilast at week 2 (roflumilast: 43.0%; vehicle: 25.7%; P < .001) and week 4 (roflumilast: 73.1%; vehicle: 47.1%; P < .001). Roflumilast was well-tolerated with a low rate of treatment-emergent adverse events. LIMITATIONS: Study limitations include the 8-week treatment period for this chronic condition. CONCLUSIONS: Once-daily roflumilast foam was superior to vehicle in leading to IGA of Clear or Almost Clear plus ≥2-point improvement from baseline at 8 weeks in patients with SD. Longer trials are needed to determine durability and safety of roflumilast foam in SD.

The Best Psoriasis Medications Emerge.

Clinical Question: What are the most effective systemic medications to treat plaque psoriasis? Bottom Line: The most effective drugs for psoriasis were infliximab, bimekizumab, ixekizumab, and risankizumab, and the clinical effectiveness was similar when these 4 drugs were compared against one another. No statistically significant differences in serious adverse events were identified in any of the drugs compared with placebo. The main limitations of this meta-analysis include the lack of assessment of clinical effectiveness beyond 52 weeks and the lack of safety assessments for nonserious adverse events.

Orismilast in moderate-to-severe psoriasis: Efficacy and safety from a 16-week, randomized, double-blinded, placebo-controlled, dose-finding, and phase 2b trial (IASOS).

BACKGROUND: Orismilast is a novel oral phosphodiesterase-4 (PDE4) B/D inhibitor being investigated as a potential treatment for moderate-to-severe psoriasis. OBJECTIVE: To evaluate efficacy and safety of orismilast modified-release formulation in moderate-to-severe psoriasis. METHODS: This multicenter, randomized (1:1:1:1 to 20, 30, 40 mg orismilast or placebo, twice daily), double-blinded, placebo-controlled, parallel-group, phase 2b, 16-week, dose-ranging study evaluated orismilast in adults with moderate-to-severe plaque psoriasis (NCT05190419). Efficacy end points were analyzed using multiple imputation. RESULTS: Of 202 randomized patients, baseline characteristics were balanced across arms, except greater severe disease proportions for orismilast vs placebo. Orismilast showed significant improvements in the primary end point, percentage change in Psoriasis Area and Severity Index (PASI), from baseline to week 16 (orismilast -52.6% to -63.7% and placebo, -17.3%; all P <.001). Greater proportions receiving orismilast achieved PASI75 (39.5%-49.0%; P <.05) and PASI90 (22.0%-28.3%; P <.05 for 20 and 40 mg) vs placebo (PASI75, 16.5% and PASI90, 8.3%) at week 16. Safety findings were as expected with PDE4 inhibition; dose-dependent tolerability effects observed. LIMITATIONS: Small sample size, disease severity imbalance between groups, limited duration and diversity in study population. CONCLUSION: Orismilast demonstrated greater efficacy vs placebo and a safety profile in line with PDE4 inhibition.

Tralokinumab Provides Clinically Meaningful Responses at Week 16 in Adults with Moderate-to-Severe Atopic Dermatitis Who Do Not Achieve IGA 0/1.

BACKGROUND AND OBJECTIVE: Investigator's Global Assessment of clear/almost clear skin (IGA 0/1) is a difficult endpoint to achieve after short-term treatment of chronic moderate-to-severe atopic dermatitis, and does not fully reflect clinically meaningful changes in other parameters. We assessed the impact of tralokinumab versus placebo on other clinically meaningful parameters in patients not achieving IGA 0/1 at week 16 using pooled data from two monotherapy phase III trials, ECZTRA 1 and 2. METHODS: This post hoc analysis included patients (n = 1328) from ECZTRA 1 and 2 who did not achieve the co-primary endpoint, IGA 0/1 at week 16 without rescue medication. Endpoints evaluating atopic dermatitis extent and severity included proportions of patients achieving IGA 0/1, 50%, 75%, and 90% improvement in Eczema Area and Severity Index (EASI-50/75/90); endpoints evaluating patient-reported outcomes included a ≥ 3-point improvement in worst daily pruritus Numerical Rating Scale (NRS), a ≥ 3-point improvement in eczema-related sleep interference (sleep) NRS, a ≥ 4-point improvement in Dermatology Life Quality Index (DLQI), and DLQI ≤ 5. Specifically, clinically meaningful responses were defined as EASI-50, a ≥ 3-point improvement in itch NRS, or a ≥ 4-point improvement in DLQI at week 16. RESULTS: Among ECZTRA 1 and 2 patients who did not achieve IGA 0/1 at week 16 without rescue medication, a significantly greater proportion of patients receiving tralokinumab versus placebo achieved EASI-50 (33.0% vs 13.0%), a ≥ 3-point improvement in itch NRS (22.6% vs 9.4%), or a ≥ 4-point improvement in DLQI (41.2% vs 24.5%) at week 16. In addition, compared with placebo, a numerically greater proportion of tralokinumab-treated patients achieved all three measures of clinically meaningful response (30% vs 18%) or a clinically meaningful change in at least one outcome (48.8% vs 28.5%). Significantly greater proportions of patients receiving tralokinumab versus placebo achieved additional clinician-reported and patient-reported outcomes, such as EASI-75 (13.5% vs 4.1%), EASI-90 (3.5% vs 1.1%), DLQI ≤ 5 (22.5% vs 12.5%), and a ≥ 3-point improvement in sleep NRS (24.5% vs 11.5%). CONCLUSIONS: Tralokinumab provided clinically meaningful responses in patients with moderate-to-severe atopic dermatitis who did not achieve IGA 0/1 at week 16 and/or used rescue medication. Using multiple validated outcome measures of both efficacy and quality of life, alongside IGA scores, can better characterize tralokinumab treatment responses in patients with moderate-to-severe atopic dermatitis.

Safety and efficacy of eblasakimab, an interleukin 13 receptor α1 monoclonal antibody, in adults with moderate-to-severe atopic dermatitis: A phase 1b, multiple-ascending dose study.

BACKGROUND: Eblasakimab, an interleukin (IL)-13 receptor α1 antagonist, blocks IL-4 and IL-13 signaling through the type 2 receptor. OBJECTIVE: The safety and efficacy of eblasakimab was evaluated in adults with moderate-to-severe atopic dermatitis (AD). METHODS: In this phase 1b randomized, double-blinded study, 52 patients with moderate-to-severe AD received weekly subcutaneous injections of eblasakimab 200, 400, or 600 mg, or placebo for 8 weeks. Primary outcome was the incidence of treatment-emergent adverse events. Secondary outcomes included percentage change in the Eczema Area and Severity Index from baseline; Eczema Area and Severity Index improvement of at least 50%, 75%, or 90% from baseline; and percentage change in the peak-pruritus numeric rating scale score from baseline. RESULTS: Treatment-emergent adverse events were reported in 47% placebo and 71% eblasakimab patients; most were considered mild or moderate and did not lead to study discontinuation. At week 8 eblasakimab 600 mg showed statistically significant improvement in mean percentage change in Eczema Area and Severity Index versus placebo (-65% vs -27%, P = .014). Other key secondary physician- and patient-reported end points were met. LIMITATIONS: Longer studies are required to confirm eblasakimab safety and efficacy in AD patients. CONCLUSIONS: Treatment of adults with moderate-to-severe AD with eblasakimab was well-tolerated and associated with significant clinical improvements versus placebo.

Deucravacitinib, a selective, allosteric tyrosine kinase 2 inhibitor, in scalp psoriasis: A subset analysis of two phase 3 randomized trials in plaque psoriasis.

BACKGROUND: Scalp involvement in plaque psoriasis is challenging to treat. OBJECTIVE: To evaluate the efficacy and safety of deucravacitinib (DEUC) in scalp psoriasis. METHODS: POETYK PSO-1 and PSO-2 were global phase 3, 52-week, double-blinded trials in adults with moderate to severe psoriasis. Patients were randomized 1:2:1 to oral placebo, DEUC 6 mg once daily, or apremilast 30 mg twice daily. This pooled secondary analysis evaluated scalp-specific Physician Global Assessment score of 0 or 1 (0/1), ≥90% improvement from baseline in Psoriasis Scalp Severity Index, and change from baseline in Psoriasis Scalp Severity Index. Adverse events were evaluated through week 16. RESULTS: Overall, 1084 patients with moderate to severe scalp psoriasis at baseline were included. At week 16, response rates were greater with DEUC versus placebo or apremilast for scalp-specific Physician Global Assessment 0/1 (64.0% vs 17.3% vs 37.7%; P < .0001), ≥90% improvement from baseline in Psoriasis Scalp Severity Index (50.6% vs 10.5% vs 26.1%; P < .0001), and change from baseline in Psoriasis Scalp Severity Index. Responses were maintained through 52 weeks with continuous DEUC. Safety was consistent with the entire study population. LIMITATIONS: Lack of data in milder scalp psoriasis. CONCLUSION: DEUC was significantly more efficacious than placebo or apremilast in improving moderate to severe scalp psoriasis and was well tolerated.

A plain language summary describing how two different concentrations of GP2017, a biosimilar adalimumab medicine, are associated with similar drug levels within the body.

WHAT IS THIS SUMMARY ABOUT?: This plain language summary explains, in simple terms, the results of a study from 2022 discussing a biosimilar medicine called GP2017 (called SDZ-ADL in this summary, sold as Hyrimoz®). This medicine is used to treat people with inflammatory conditions. This study investigated a new, high-concentration formulation of GP2017 (SDZ-ADL-HCF) in order to show that the high concentration option acts the same way in the body as SDZ-ADL. SDZ-ADL-HCF has been submitted for regulatory approval to health authorities on the basis of this study and was recently approved by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for people with the inflammatory conditions that SDZ-ADL is used to treat. This newly developed formulation provides the option for receiving injections less often with reduced volumes which can have a positive impact on the injection experience and increase patient convenience. WHAT WAS THE AIM OF THE CURRENT STUDY?: This study looked at the pharmacokinetics of SDZ-ADL and SDZ-ADL-HCF, meaning it compared how the active medicine behaved in the body at different times after the injection of each of the formulations. The study also looked at how each formulation was recognized by the body's immune system (known as immunogenicity), and the side effects associated with each formulation. This study was randomly assigned and double-blinded, meaning that neither the participants nor the researchers knew which formulation each participant received. This reduces the risk of bias in the results. WHAT WERE THE FINDINGS FROM THE CURRENT STUDY?: The study found that an injection of SDZ-ADL-HCF resulted in similar amounts of the medicine being present within the blood as an injection of SDZ-ADL. This information was needed for the approval of SDZ-ADL-HCF. Participants also experienced similar immune reactions and the number of participants with side effects was similar between both concentrations of medicine. The results confirmed that SDZ-ADL-HCF behaves in the same way in the body and is expected to have the same treatment effects as SDZ-ADL, while at the same time offering an improved formulation with a more positive injection experience and increased patient convenience.
