Comparative effectiveness of less commonly used systemic monotherapies and common combination therapies for moderate to severe psoriasis in the clinical setting.

BACKGROUND: The effectiveness of psoriasis therapies in real-world settings remains relatively unknown. OBJECTIVE: We sought to compare the effectiveness of less commonly used systemic therapies and commonly used combination therapies for psoriasis. METHODS: This was a multicenter cross-sectional study of 203 patients with plaque psoriasis receiving less common systemic monotherapy (acitretin, cyclosporine, or infliximab) or common combination therapies (adalimumab, etanercept, or infliximab and methotrexate) compared with 168 patients receiving methotrexate evaluated at 1 of 10 US outpatient dermatology sites participating in the Dermatology Clinical Effectiveness Research Network. RESULTS: In adjusted analyses, patients on acitretin (relative response rate 2.01; 95% confidence interval [CI] 1.18-3.41), infliximab (relative response rate 1.93; 95% CI 1.26-2.98), adalimumab and methotrexate (relative response rate 3.04; 95% CI 2.12-4.36), etanercept and methotrexate (relative response rate 2.22; 95% CI 1.25-3.94), and infliximab and methotrexate (relative response rate 1.72; 95% CI 1.10-2.70) were more likely to have clear or almost clear skin compared with patients on methotrexate. There were no differences among treatments when response rate was defined by health-related quality of life. LIMITATIONS: Single time point assessment may result in overestimation of effectiveness. CONCLUSIONS: The efficacy of therapies in clinical trials may overestimate their effectiveness as used in clinical practice. Although physician-reported relative response rates were different among therapies, absolute differences were small and did not correspond to differences in patient-reported outcomes

Phase 3 trials of ixekizumab in moderate-to-severe plaque psoriasis

BACKGROUND Two phase 3 trials (UNCOVER-2 and UNCOVER-3) showed that at 12 weeks of treatment, ixekizumab, a monoclonal antibody against interleukin-17A, was superior to placebo and etanercept in the treatment of moderate-to-severe psoriasis. We report the 60-week data from the UNCOVER-2 and UNCOVER-3 trials, as well as 12-week and 60-week data from a third phase 3 trial, UNCOVER-1. METHODS We randomly assigned 1296 patients in the UNCOVER-1 trial, 1224 patients in the UNCOVER-2 trial, and 1346 patients in the UNCOVER-3 trial to receive subcutaneous injections of placebo (placebo group), 80 mg of ixekizumab every 2 weeks after a starting dose of 160 mg (2-wk dosing group), or 80 mg of ixekizumab every 4 weeks after a starting dose of 160 mg (4-wk dosing group). Additional cohorts in the UNCOVER-2 and UNCOVER-3 trials were randomly assigned to receive 50 mg of etanercept twice weekly. At week 12 in the UNCOVER-3 trial, the patients entered a long-term extension period during which they received 80 mg of ixekizumab every 4 weeks through week 60; at week 12 in the UNCOVER-1 and UNCOVER-2 trials, the patients who had a response to ixekizumab (defined as a static Physicians Global Assessment [sPGA] score of 0 [clear] or 1 [minimal psoriasis]) were randomly reassigned to receive placebo, 80 mg of ixekizumab every 4 weeks, or 80 mg of ixekizumab every 12 weeks through week 60. Coprimary end points were the percentage of patients who had a score on the sPGA of 0 or 1 and a 75% or greater reduction from baseline in Psoriasis Area and Severity Index (PASI 75) at week 12. RESULTS In the UNCOVER-1 trial, at week 12, the patients had better responses to ixekizumab than to placebo; in the 2-wk dosing group, 81.8% had an sPGA score of 0 or 1 and 89.1% had a PASI 75 response; in the 4-wk dosing group, the respective rates were 76.4% and 82.6%; and in the placebo group, the rates were 3.2% and 3.9% (P<0.001 for all comparisons of ixekizumab with placebo). In the UNCOVER-1 and UNCOVER-2 trials, among the patients who were randomly reassigned at week 12 to receive 80 mg of ixekizumab every 4 weeks, 80 mg of ixekizumab every 12 weeks, or placebo, an sPGA score of 0 or 1 was maintained by 73.8%, 39.0%, and 7.0% of the patients, respectively. Patients in the UNCOVER-3 trial received continuous treatment of ixekizumab from weeks 0 through 60, and at week 60, at least 73% had an sPGA score of 0 or 1 and at least 80% had a PASI 75 response. Adverse events reported during ixekizumab use included neutropenia, candidal infections, and inflammatory bowel disease. CONCLUSIONS In three phase 3 trials involving patients with psoriasis, ixekizumab was effective through 60 weeks of treatment. As with any treatment, the benefits need to be weighed against the risks of adverse events. The efficacy and safety of ixekizumab beyond 60 weeks of treatment are not yet known

Safety and Efficacy of Lebrikizumab in Adolescent Patients with Moderate-to-Severe Atopic Dermatitis: A 52-Week, Open-Label, Phase 3 Study.

IntroductionAtopic dermatitis (AD) is a chronic inflammatory skin disorder with limited treatment options for adolescents with moderate-to-severe disease. Lebrikizumab, a monoclonal antibody targeting interleukin (IL)-13, demonstrated clinical benefit in previous Phase 3 trials: ADvocate1 (NCT04146363), ADvocate2 (NCT04178967), and ADhere (NCT04250337). We report 52-week safety and efficacy outcomes from ADore (NCT04250350), a Phase 3, open-label study of lebrikizumab in adolescent patients with moderate-to-severe AD. The primary endpoint was to describe the proportion of patients who discontinued from study treatment because of adverse events (AEs) through the last treatment visit.MethodsAdolescent patients (N = 206) (≥ 12 to &lt; 18&nbsp;years old, weighing ≥ 40&nbsp;kg) with moderate-to-severe AD received subcutaneous lebrikizumab 500&nbsp;mg loading doses at baseline and Week 2, followed by 250&nbsp;mg every 2&nbsp;weeks (Q2W) thereafter. Safety was monitored using reported AEs, AEs leading to treatment discontinuation, vital signs, growth assessments, and laboratory testing. Efficacy analyses included Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), Body Surface Area (BSA), (Children's) Dermatology Life Quality Index ((C)DLQI), and Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, and PROMIS Depression.Results172 patients completed the treatment period. Low frequencies of SAEs (n = 5, 2.4%) and AEs leading to treatment discontinuation (n = 5, 2.4%) were reported. Overall, 134 patients (65%) reported at least one treatment-emergent AE (TEAE), most being mild or moderate in severity. In total, 62.6% achieved IGA (0,1) with ≥&nbsp;2-point improvement from baseline and 81.9% achieved EASI-75 by Week 52. The EASI mean percentage improvement from baseline to Week 52 was 86.0%. Mean BSA at baseline was 45.4%, decreasing to 8.4% by Week 52. Improvements in mean change from baseline (CFB) to Week 52 were observed in DLQI (baseline 12.3; CFB - 8.9), CDLQI (baseline 10.1; CFB - 6.5), PROMIS Anxiety (baseline 51.5; CFB - 6.3), and PROMIS Depression (baseline 49.3; CFB - 3.4) scores.ConclusionsLebrikizumab 250&nbsp;mg Q2W had a safety profile consistent with previous trials and significantly improved AD symptoms and quality of life, with meaningful responses at Week 16 increasing by Week 52.Trial registrationClinicalTrials.gov identifier, NCT04250350

Efficacy of Dupilumab in Different Racial Subgroups of Adults With Moderate-to-Severe Atopic Dermatitis in Three Randomized, Placebo-Controlled Phase 3 Trials

Dupilumab, a monoclonal antibody that blocks the shared receptor subunit for interleukin (IL)-4 and IL-13, is currently approved for the treatment of adults with inadequately controlled moderate-to-severe atopic dermatitis (AD). The efficacy and safety of dupilumab for AD among racial subgroups is unknown. This post hoc analysis from three phase 3 trials assessed the efficacy and safety of dupilumab vs placebo by racial subgroup (White, Asian, Black/African American). Data from LIBERTY AD SOLO 1 (NCT02277743), SOLO 2 (NCT02277769), and CHRONOS (NCT02260986) were pooled. Outcomes included mean and percent change from baseline to week 16 in the key therapeutic domains Eczema Area and Severity Index (EASI), Peak Pruritus Numerical Rating Scale (NRS), Dermatology Life Quality Index (DLQI), and Patient-Oriented Eczema Measure, as well as Investigator’s Global Assessment and pain or discomfort assessed by the European Quality of Life-5 Dimensions 3 level questionnaire. A total of 2,058 patients (White n=1,429, Asian n=501, Black/African American n=128) were included in the current analysis. Baseline demographics and disease characteristics were balanced between treatment groups and racial subgroups. In the three trials, dupilumab significantly (P\u3c0.0001) improved all assessed outcomes compared with placebo in the White and Asian subgroups. In the smaller Black/African American subgroup, dupilumab significantly (P\u3c0.0001) improved EASI endpoints and mean changes in Peak Pruritus NRS and DLQI vs placebo, with positive numeric trends favoring dupilumab in all other endpoints. Dupilumab was generally well tolerated, with an acceptable safety profile in all racial subgroups. Serious adverse events occurred more frequently with placebo; treatment discontinuations due to adverse events were rare in all treatment groups. Significant clinical improvement and a favorable benefit-risk profile can be achieved with dupilumab treatment in patients of White, Asian, and Black/African American racial subgroups with moderate-to-severe AD inadequately controlled with topical medications.

Comparative effectiveness of commonly used systemic treatments or phototherapy for moderate to severe plaque psoriasis in the clinical practice setting.

OBJECTIVE: To compare the effectiveness of biologic systemic therapy, nonbiologic systemic therapy, and phototherapy for treatment of psoriasis. DESIGN: A cross-sectional design was used. SETTING: Ten outpatient dermatology sites across the United States participating in the Dermatology Clinical Effectiveness Research Network contributed to the study. PARTICIPANTS: A total of 713 patients with plaque psoriasis receiving systemic monotherapy (ie, methotrexate sodium, adalimumab, etanercept, or ustekinumab) or narrowband UV-B phototherapy. MAIN OUTCOME MEASURES: The primary outcome of the study was clear or almost clear skin on the Physician Global Assessment scale. Secondary outcomes were score on the Psoriasis Area and Severity Index, affected body surface area, and score on the Dermatology Life Quality Index. RESULTS: The proportion of patients with clear or almost clear ratings on the Physician Global Assessment scale differed among treatments: methotrexate (23.8%), adalimumab (47.7%), etanercept (34.2%), ustekinumab (36.1%), and narrowband UV-B (27.6%) (P \u3c .001). In adjusted analyses, patients receiving adalimumab (relative response rate, 2.15; 95% CI, 1.60-2.90), etanercept (1.45; 1.06-1.97), and ustekinumab (1.57; 1.06-2.32) were more likely to have clear or almost clear skin vs patients receiving methotrexate. Patients receiving phototherapy showed no significant difference (1.35; 95% CI, 0.93-1.96) compared with those receiving methotrexate. No response difference was observed with respect to quality of life. Treatment doses were double the recommended doses in 36.1% of patients taking etanercept and 11.8% of those taking adalimumab;10.6% of patients undergoing phototherapy received the recommended treatment frequency. CONCLUSIONS: The effectiveness of psoriasis therapies in clinical practice may be lower than that reported in previous trials. Although relative differences in objective response rates among therapies may exist, absolute differences are small and may not be clinically significant. Dosing of common therapies varied from trial recommendations. These results provide novel benchmarks emphasizing the critical importance of studying effectiveness in real-world practice

Family-Focused Treatment for Adolescents and Young Adults at High Risk for Psychosis: Results of a Randomized Trial

OBJECTIVE: Longitudinal studies have begun to clarify the phenotypic characteristics of adolescents and young adults at clinical high risk for psychosis. This 8-site randomized trial examined whether a 6-month program of family psychoeducation was effective in reducing the severity of attenuated positive and negative psychotic symptoms and enhancing functioning among individuals at high risk. METHOD: Adolescents and young adults (mean 17.4±4.1 years) with attenuated positive psychotic symptoms, brief and intermittent psychosis, or genetic risk with functional deterioration were randomly assigned to 18 sessions of family-focused therapy for individuals at clinical high risk (FFT-CHR) in 6 months or 3 sessions of family psychoeducation (enhanced care, or EC). FFT-CHR included psychoeducation about early signs of psychosis, stress management, communication training, and problem-solving skills training, whereas EC focused on symptom prevention. Independent evaluators assessed participants at baseline and 6 months on positive and negative symptoms and social-role functioning. RESULTS: Of 129 participants, 102 (79.1%) were followed at 6 months. Participants in FFT-CHR showed greater improvements in attenuated positive symptoms over 6 months than participants in EC (F[1,97]=5.49, P=.02). Negative symptoms improved independently of psychosocial treatments. Changes in psychosocial functioning depended on age: participants over 19 years showed more role improvement in FFT-CHR, whereas participants between 16 and 19 years showed more role improvement in EC. The results were independent of concurrent pharmacotherapy. CONCLUSION: Interventions that focus on improving family relationships may have prophylactic efficacy in individuals at high risk for psychosis. Future studies should examine the specificity of effects of family intervention compared to individual therapy of the same duration and frequency

Genetic Dissection of Acute Anterior Uveitis Reveals Similarities and Differences in Associations Observed With Ankylosing Spondylitis

OBJECTIVE: To use high-density genotyping to investigate the genetic associations of acute anterior uveitis (AAU) in patients with and those without ankylosing spondylitis (AS). METHODS: We genotyped samples from 1,711 patients with AAU (either primary or combined with AS), 2,339 AS patients without AAU, and 10,000 control subjects on an Illumina Immunochip Infinium microarray. We also used data for AS patients from previous genome-wide association studies to investigate the AS risk locus ANTXR2 for its putative effect in AAU. ANTXR2 expression in mouse eyes was investigated by real-time quantitative reverse transcription-polymerase chain reaction. RESULTS: A comparison between all patients with AAU and healthy control subjects showed strong association over HLA-B, corresponding to the HLA-B27 tag single-nucleotide polymorphism rs116488202. The association of 3 non-major histocompatibility complex loci, IL23R, the intergenic region 2p15, and ERAP1, reached genome-wide significance (P < 5 × 10(-8) ). Five loci harboring the immune-related genes IL10-IL19, IL18R1-IL1R1, IL6R, the chromosome 1q32 locus harboring KIF21B, as well as the eye-related gene EYS, were also associated, reaching a suggestive level of significance (P < 5 × 10(-6) ). Several previously confirmed AS associations demonstrated significant differences in effect size between AS patients with AAU and AS patients without AAU. ANTXR2 expression varied across eye compartments. CONCLUSION: These findings of both novel AAU-specific associations and associations shared with AS demonstrate overlapping but also distinct genetic susceptibility loci for AAU and AS. The associations in IL10 and IL18R1 are shared with inflammatory bowel disease, suggesting common etiologic pathways
