RESUMO
Endocannabinoids (ECs), such as anandamide and 2-arachidonyl glycerol (2-AG), contribute to the pathology of inflammatory, malignant, cardiovascular, metabolic and mental diseases. The reliability of quantitative analyses in biological fluids of ECs and endocannabinoid-like (EC-like) substances depends on pre-analytical conditions such as temperature and "time-to-centrifugation". Standardization of these parameters is critical for valid quantification and implementation in clinical research. In this study, we compared concentrations obtained with GlucoEXACT blood collection tubes versus K3EDTA tubes and employed the optimized procedure to assess ECs profiles in patients with inflammatory skin disease and healthy controls. A UHPLC-MS/MS method was validated for human plasma from GlucoEXACT blood collection tubes according to EMA and FDA guidelines, and pre-analytical conditions were systematically modified to assess analyte stability and optimize the procedures. The results showed significantly lower concentrations of ECs and EC-like substance concentrations with GlucoEXACT tubes compared with K3EDTA tubes, and GlucoEXACT extended the time window of stable concentrations. The strongest method-disagreement occurred for 1/2-AG suggesting that GlucoEXACT delayed ex vivo isomer rearrangement. Hence, GlucoExact tubes were superior in terms of stability and reliability. However, although absolute concentrations obtained with GlucoExact and K3EDTA differed, linear regression studies showed high agreement (except for 1/2-AG), and both methods showed similar EC profiles and similar disease-dependent pro-inflammatory patterns in dermatology patients. Hence, despite the obstacles in EC analyses, implementation of optimized pre-analytical blood collection and sample processing procedures provide reliable insight into peripheral ECs.

Auto-inflammatory skin diseases place considerable symptomatic and emotional burden on the affected and put pressure on healthcare expenditures. Although most apparent symptoms manifest on the skin, the systemic inflammation merits a deeper analysis beyond the surface. We set out to identify systemic commonalities, as well as differences in the metabolome and lipidome when comparing between diseases and healthy controls. Lipidomic and metabolomic LC-MS profiling was applied, using plasma samples collected from patients suffering from atopic dermatitis, plaque-type psoriasis or hidradenitis suppurativa or healthy controls. Plasma profiles revealed a notable shift in the non-enzymatic anti-oxidant defense in all three inflammatory disorders, placing cysteine metabolism at the center of potential dysregulation. Lipid network enrichment additionally indicated the disease-specific provision of lipid mediators associated with key roles in inflammation signaling. These findings will help to disentangle the systemic components of autoimmune dermatological diseases, paving the way to individualized therapy and improved prognosis.

INTRODUCTION: Given the chronic nature of psoriasis (PsO), more studies are needed that directly compare the effectiveness of different biologics over long observation periods. This study compares the effectiveness and durability through 12 months of anti-interleukin (IL)-17A biologics relative to other approved biologics in patients with moderate-to-severe psoriasis in a real-world setting. METHODS: The Psoriasis Study of Health Outcomes (PSoHO) is an ongoing 3-year, prospective, non-interventional cohort study of 1981 adults with chronic moderate-to-severe plaque psoriasis initiating or switching to a new biologic. The study compares the effectiveness of anti-IL-17A biologics with other approved biologics and provides pairwise comparisons of seven individual biologics versus ixekizumab. The primary outcome was defined as the proportion of patients who had at least a 90% improvement in Psoriasis Area and Severity Index score (PASI90) and/or a score of 0 or 1 in static Physician Global Assessment (sPGA). Secondary objective comparisons included the proportion of patients who achieved PASI90, PASI100, a Dermatology Life Quality Index (DLQI) score of 0 or 1, and three different measures of durability of treatment response. Unadjusted response rates are presented alongside the primary analysis, which uses frequentist model averaging (FMA) to evaluate the adjusted comparative effectiveness. RESULTS: Compared to the other biologics cohort, the anti-IL-17A cohort had a higher response rate (68.0% vs. 65.1%) and significantly higher odds of achieving the primary outcome at month 12. The two cohorts had similar response rates for PASI100 (40.5% and 37.1%) and PASI90 (53.9% and 51.7%) at month 12, with no significant differences between the cohorts in the adjusted analyses. At month 12, the response rates across the individual biologics were 53.5-72.6% for the primary outcome, 27.6-48.3% for PASI100, and 41.7-61.4% for PASI90. CONCLUSIONS: These results show the comparative effectiveness of biologics at 6 and 12 months in the real-world setting.
RESUMO
BACKGROUND: The fixed dose combination of calcipotriene (CAL) and betamethasone dipropionate (BDP) is a well-established topical treatment option for psoriasis based on strong scientific rationale for the single agents having complementary efficacy and safety. CAL/BDP PAD-cream is an easily spreadable cream based on PAD Technology™, an innovative formulation and drug delivery system. OBJECTIVES AND METHODS: A Phase 3, multicentre, randomized, investigator-blind, active and vehicle-controlled trial enrolling 490 patients with mild to moderate psoriasis according to the Physician Global Assessment (PGA) scale was conducted in three European countries. Products were applied once daily for 8 weeks. The aim of the trial was to evaluate the efficacy and safety of CAL/BDP PAD-cream as well as treatment acceptability compared to CAL/BDP gel and PAD-cream vehicle. Primary endpoint was percentage change in modified Psoriasis Area and Severity Index (mPASI) from baseline to Week 8. RESULTS: The percentage mean change from baseline to Week 8 in mPASI for CAL/BDP PAD-cream (67.5%) was superior compared to PAD-cream vehicle (11.7%; p < 0.0001) and non-inferior to CAL/BDP gel (63.5%). The proportion of patients achieving PGA treatment success (at least two-step improvement to clear or almost clear) after 8 weeks was superior for CAL/BDP PAD-cream (50.7%) compared to PAD-cream vehicle (6.1%, p < 0.0001) and statistically significantly greater than CAL/BDP gel (42.7%, p = 0.0442). Patient-reported psoriasis treatment convenience score (PTCS) for CAL/BDP PAD-cream was rated superior to CAL/BDP gel at Week 8 (p < 0.0001) and the mean change in DLQI from baseline to Week 8 improved statistically significantly more in the CAL/BDP PAD-cream group compared to both PAD-cream vehicle (p < 0.0001) and CAL/BDP gel (p = 0.0110). Safety assessments during the trial demonstrated that CAL/BDP PAD-cream was well-tolerated. CONCLUSION: CAL/BDP PAD-cream is a novel topical treatment of psoriasis that has a high efficacy and a favourable safety profile combined with a superior patient-reported treatment convenience.

BACKGROUND: Guselkumab is an interleukin (IL)-23 inhibitor with demonstrated efficacy in patients with psoriasis. OBJECTIVES: Evaluate the impact of early disease intervention on clinical responses following 28 weeks of guselkumab treatment in patients with moderate-to-severe plaque psoriasis. Correlate clinical response and disease duration data with serum biomarker data. METHODS: GUIDE is a phase IIIb randomized, double-blind, parallel-group, multicentre study of adults with moderate-to-severe plaque psoriasis. In study part 1, patients with a short disease duration (SDD [≤2 years]) or a long disease duration (LDD [>2 years]) received guselkumab 100 mg at Week (W) 0, 4, 12, and 20. Those achieving complete skin clearance at W20 and W28 were defined as a super responder (SRe). A multivariable logistic regression analysed the association between baseline factors and the likelihood of becoming an SRe. The relationship between clinical response, disease duration and serum biomarker data was assessed at W0 and 4. RESULTS: In total, 880 patients were enrolled (SDD/LDD = 40.6%/59.4% of patients). More SDD than LDD patients achieved absolute Psoriasis Area and Severity Index (PASI) = 0 at W28 (51.8% vs. 39.4%) and were SRes (43.7% vs. 28.1% [overall 34.4%]). SDD patients also achieved PASI = 0 quicker than LDD patients (median 141 vs. 200 days). Disease duration and prior biologic use had the greatest impact on becoming an SRe, with no strong association among these independent variables. At baseline, there were no significant differences in the serum biomarker levels of IL-17A, IL-17F, IL-22 and ß-defensin 2 between SDD and LDD patients, or between SRe and non-SRe patients. Guselkumab rapidly decreased these markers of systemic inflammation across all patient groups analysed at W4. Guselkumab was well tolerated. CONCLUSIONS: Guselkumab efficacy was consistent across subpopulations, on the skin and systemically. The proportion of SRes was higher in SDD than LDD patients, indicating early treatment intervention may improve clinical outcomes.

BACKGROUND: Rapid skin improvement is a key treatment goal of patients with moderate-to-severe psoriasis (PsO). OBJECTIVES: To compare the speed of clinical improvement of approved biologics on the symptoms and signs of psoriasis assessed by patients using the validated Psoriasis Symptoms and Signs Diary (PSSD) through 12 weeks. METHODS: Psoriasis Study of Health Outcomes (PSoHO) is an international, prospective, non-interventional study that compares the effectiveness of anti-interleukin (IL)-17A biologics versus other biologics, together with pairwise comparisons of ixekizumab versus five individual biologics in patients with PsO. Using the PSSD 7-day recall period, patients assessed the symptoms (itch, skin tightness, burning, stinging and pain) and signs (dryness, cracking, scaling, shedding/flaking, redness and bleeding) of their psoriasis (0-10). Symptom and sign summary scores (0-100) are derived from the average of individual scores. Percentage change in summary scores and proportion of patients with clinically meaningful improvements (CMI) in PSSD summary and individual scores are evaluated weekly. Longitudinal PSSD data are reported as observed with treatment comparisons analysed using mixed model for repeated measures (MMRM) and generalized linear mixed models (GLMM). RESULTS: Across cohorts and treatments, eligible patients (n = 1654) had comparable baseline PSSD scores. From Week 1, the anti-IL-17A cohort achieved significantly larger score improvements in PSSD summary scores and a higher proportion of patients showed CMIs compared to the other biologics cohort through 12 weeks. Lower PSSD scores were associated with a greater proportion of patients reporting their psoriasis as no longer impacting their quality-of-life (DLQI 0,1) and a high level of clinical response (PASI100). Results also indicate a relationship between an early CMI in PSSD score at Week 2 and PASI100 score at Week 12. CONCLUSIONS: Treatment with anti-IL-17A biologics, particularly ixekizumab, resulted in rapid and sustained patient-reported improvements in psoriasis symptoms and signs compared with other biologics in a real-world setting.

BACKGROUND: Risankizumab has demonstrated durable, high rates of efficacy in patients with moderate-to-severe plaque psoriasis as assessed by the achievement of relative Psoriasis Area and Severity Index (PASI) improvement and Dermatology Life Quality Index (DLQI) 0/1. OBJECTIVES: The aim of this post hoc analysis is to assess the achievement of absolute PASI thresholds and related improvements in health-related quality of life (HRQoL) in patients with moderate-to-severe plaque psoriasis treated with (i) risankizumab compared with ustekinumab, and (ii) long-term (>52 weeks to 172 weeks) risankizumab. METHODS: Data from patients randomised to 150 mg risankizumab or 45 or 90 mg ustekinumab in replicate randomised controlled trials UltIMMa-1 and UltIMMa-2 were analysed for the achievement of absolute PASI thresholds PASI ≤ 3, PASI ≤ 1, and PASI = 0, time to achieve these thresholds, and combined PASI and DLQI endpoints. Data from pat ients initially randomised to risankizumab who continued on risankizumab in the open-label extension study LIMMitless were analysed for the achievement of absolute PASI levels, mean DLQI scores, and DLQI 0/1. RESULTS: Significantly greater proportions of patients treated with risankizumab compared with ustekinumab achieved PASI ≤ 3, PASI ≤ 1, and PASI = 0, as well as combined endpoints for absolute PASI and DLQI [(PASI ≤ 3 and DLQI ≤ 5) or (PASI ≤ 1 and DLQI 0/1)]. The median time to first achieve PASI ≤ 3, PASI ≤ 1, and PASI = 0 was significantly lower for risankizumab-treated patients compared with ustekinumab-treated patients. Among patients treated with long-term risankizumab, more than 90% achieved PASI ≤ 3 though week 172 and more than 80% achieved DLQI 0/1. Low absolute PASI scores corresponded with low mean absolute DLQI scores through week 172 of continuous risankizumab treatment. CONCLUSIONS: Risankizumab treatment demonstrated high rates of rapid and durable efficacy as measured by absolute PASI thresholds and improvements in patient HRQoL.

BACKGROUND: Plaque psoriasis is a common, chronic and relapsing inflammatory skin disease clinically characterized by erythema and scaling desquamation. As over 90% of psoriasis patients benefit from topical therapies, local treatments continue to play an eminent role in management strategies. One such topical treatment is the fixed dose combination of calcipotriol (CAL) and betamethasone dipropionate (BDP). OBJECTIVES: Pooled analysis of two different phase 3 clinical trails to compare superiority regarding efficacy, safety and quality of life (QoL) between CAL/BDP PAD-cream and CAL/BDP TS. METHODS: The data from two phase 3, multicentre, randomized, investigator-blind, active and vehicle-controlled trials enrolling patients with psoriasis were pooled and analysed. Investigational products included a CAL/BDP cream based on PAD™ Technology (PAD-cream) designed for high skin penetration and increased patient preference, an active control (marketed CAL/BDP topical suspension/gel, in the following abbreviated as CAL/BDP TS) and cream vehicle, which were applied once daily for 8 weeks. RESULTS: Efficacy and safety of the novel CAL/BDP PAD-cream formulation for the topical treatment of psoriasis demonstrated superiority for all efficacy end points after 8 weeks of treatment. PGA treatment success for CAL/BDP PAD-cream (43.2%) was greater than CAL/BDP TS (31.9%; P < 0.0001), the mean per cent reduction in mPASI for CAL/BDP PAD-cream was 64.6% compared to 56.4% for CAL/BDP TS (P < 0.0001) and DLQI 0/1 was obtained by 43.8% in the CAL/BDP PAD-cream group versus 34.2% in the CAL/BDP TS group (P = 0.0005). There was no adverse drug reaction reported with a frequency of >1%, associated with the CAL/BDP PAD-cream. CONCLUSIONS: The novel fixed dose combination CAL/BDP PAD-cream offers greater efficacy, superior patient QoL and equivalent favourable safety for the topical treatment of psoriasis, in comparison to the currently available topical suspension/gel.

BACKGROUND: Fumaric acid esters (FAEs; Fumaderm® ) are the most frequently prescribed first-line systemic treatment for moderate-to-severe plaque psoriasis in Germany. Risankizumab (Skyrizi® ) is a humanized IgG1 monoclonal antibody that specifically binds to the p19 subunit of interleukin 23. OBJECTIVES: To compare risankizumab treatment to FAEs in patients with psoriasis. METHODS: This phase III randomized, active-controlled, open-label study with blinded assessment of efficacy was conducted in Germany. Patients were randomized (1 : 1) to subcutaneous risankizumab 150 mg (weeks 0, 4 and 16) or oral FAEs at increasing doses from 30 mg daily (week 0) up to 720 mg daily (weeks 8-24). Enrolled patients were adults naïve to and candidates for systemic therapy, with chronic moderate-to-severe plaque psoriasis. Phototherapy was not allowed within 14 days before or during the study. RESULTS: Key efficacy endpoints were met at week 24 for risankizumab (n = 60) vs. FAEs (n = 60) (P < 0·001): achievement of a ≥ 90% improvement in Psoriasis Area and Severity Index (PASI; primary endpoint 83·3% vs. 10·0%), ≥ 100% improvement in PASI (50·0% vs. 5·0%), ≥ 75% improvement in PASI (98·3% vs. 33·3%), ≥ 50% improvement in PASI (100% vs. 53·3%) and a Static Physician's Global Assessment of clear/almost clear (93·3% vs. 38·3%). The rates of gastrointestinal disorders, flushing, lymphopenia and headache were higher in the FAE group. One patient receiving risankizumab reported a serious infection (influenza, which required hospitalization). There were no malignancies, tuberculosis or opportunistic infections in either treatment arm. CONCLUSIONS: Risankizumab was found to be superior to FAEs, providing earlier and greater improvement in psoriasis outcomes that persisted with continued treatment, and more favourable safety results, which is consistent with the known safety profile. No new safety signals for risankizumab or FAEs were observed.

Systemic treatment together with radical surgical excision is the most important treatment option for all severity grades of hidradenitis suppurativa. Tetracycline in mild-to-moderate forms and clindamycin in combination with rifampicin in moderate-to-severe forms are guideline-compliant first-line therapy with a good clinical response. Other antibiotics such as ertepenem or multiple combinations are recommended as last-line therapy due to a lack of data. Success rate with dapsone and retinoids, on the other hand, are insufficient-only acitretin can be recommended on the basis of the available studies, but with limited success. With the TNF-alpha blocker adalimumab, an effective and safe long-term therapy is available-further biologics are in clinical trials and could significantly expand the treatment portfolio in the future.

BACKGROUND: Nemolizumab is a humanized anti-IL-31 receptor blocker in phase 3 for atopic dermatitis (AD). OBJECTIVE: Analyse onset of action of nemolizumab 30 mg and compare efficacy and safety vs placebo (SC q4wk plus loading dose) in moderate-to-severe AD. METHODS: Post hoc analysis of patients with Eczema Area and Severity Index (EASI) scores ≥ 16 from a phase 2b trial of moderate-to-severe AD. Endpoints were change in EASI score at week 16, peak pruritus numeric rating scale (PP-NRS), Investigator's Global Assessment (IGA), changes in sleep and responders with ≥ 4-point improvement on PP-NRS. RESULTS: There was a significantly greater itch relief apparent by Day 2 (-22.8% vs -12.3% PP-NRS; P = 0.005) which continued to improve through week 16 (-68.5% vs -30.9% PP-NRS; P < 0.001). At week 16, PP-NRS ≥ 4-point response of itch was observed in 68.0% nemolizumab vs 15.9% placebo patients (P ≤ 0.001). There was also a rapid improvement of sleep disturbance with nemolizumab 30 mg, with a significant separation from placebo by Day 3 (-26.6% vs -9.0%; P < 0.001) which further improved till week 16 (-76.0% vs -36.5%; P < 0.001). Also for the EASI score a separation between groups in favour of nemolizumab was observed by week 1 (P ≤ 0.001), which increased through week 16 (-68.6% vs. -42.6%; P = 0.002). Finally, the degree of response was greater in nemolizumab-treated patients; clinically relevant reductions of 75% EASI were observed in 50.0% of nemolizumab patients versus 15.9% of placebo patients, while 90% reductions were reported for 36.0% and 6.8% of patients, respectively (P < 0.001 for both). IGA success (score of 0/1) was 32.0% for nemolizumab vs 6.8% for placebo (P = 0.002). Nemolizumab was safe and well-tolerated in this population; nasopharyngitis and upper respiratory tract infection were the most common adverse events. CONCLUSIONS: Nemolizumab resulted in very rapid, sustained improvements of inflammation, pruritus and sleep in patients with EASI ≥ 16 at baseline.

BACKGROUND: In a phase 3 clinical study, patients from Germany with moderate to severe psoriasis who were naïve to systemic treatment and received risankizumab had greater and more rapid disease improvements compared with those who received fumaric acid esters (FAEs). OBJECTIVE: To evaluate patient-reported outcomes (PROs) in patients treated with risankizumab compared with FAEs. METHODS: Adult patients were randomized 1:1 to receive either risankizumab 150 mg subcutaneous injections at weeks 0, 4 and 16 or FAEs (Fumaderm® ) provided according to the prescribing label. PRO secondary endpoints assessed were Psoriasis Symptom Scale (PSS), Dermatology Life Quality Index (DLQI), 36-Item Short Form Health Survey, version 2 (SF-36v2), Patient Benefit Index (PBI), Hospital Anxiety and Depression Scale (HADS), Patient Global Assessment (PtGA) and European Quality of Life 5 Dimensions 5 Level (EQ-5D-5L). PROs were assessed at weeks 0, 16 and 24. RESULTS: Sixty patients each were randomized to receive risankizumab or FAEs. A significant PSS improvement was observed with risankizumab vs. FAEs at weeks 16 and 24 for total and psoriasis-associated redness, itching and burning scores (P < 0.001). DLQI scores were significantly lower (reflecting better health-related quality of life) with risankizumab vs. FAEs, with least squares (LS) mean differences of -7.4 and -7.6 at weeks 16 and 24, respectively (both P < 0.001). Patients randomized to risankizumab also had larger improvements in SF-36 Physical and Mental Component Summary scores, HADS anxiety and depression scores, PtGA, and EQ-5D-5L index and visual analogue scale scores (all P ≤ 0.002) at weeks 16 and 24 compared with FAEs. PBI was significantly higher, indicating greater benefit, with risankizumab vs. FAEs, with an LS mean difference of 1.1 and 1.3 at weeks 16 and 24, respectively (both P < 0.001). CONCLUSIONS: Risankizumab provides significant benefits over FAEs in improving PROs across several dimensions in patients with moderate to severe psoriasis.

BACKGROUND: Brodalumab is a fully human monoclonal immunoglobulin IgG2 antibody that binds to the human IL-17 receptor subunit A and by that inhibits the biologic action of IL-17A, IL-17F, IL-17C and IL-17E. Therapy with fumaric acid esters (FAE) is a well established and widely used first-line systemic treatment for subjects with moderate-to-severe plaque psoriasis. OBJECTIVES: To compare brodalumab to FAE in terms of clinical efficacy, patient-reported outcomes and safety in subjects with moderate-to-severe plaque psoriasis who were naïve to systemic treatment. METHODS: Eligible subjects were randomized 1 : 1 to 210 mg brodalumab injections or oral FAE according to product label in this 24-week, open-label, assessor-blinded, multi-centre, head-to-head phase 4 trial. The primary endpoints were having PASI75 and having sPGA score of 0 or 1 (sPGA 0/1). Subjects with missing values for the primary endpoints were considered non-responders. RESULTS: A total of 210 subjects were randomized. 91/105 subjects completed brodalumab treatment and 58/105 subjects completed FAE treatment. At Week 24, significantly more subjects in the brodalumab group compared to the FAE group had PASI75 (81.0% vs. 38.1%, P < 0.001) and sPGA 0/1 (64.8% vs. 20.0%, P < 0.001). In the brodalumab group, the median time to both PASI75 and to PASI90 was significantly shorter than in the FAE group (4.1 weeks vs. 16.4 weeks, and 7.4 weeks vs. 24.4 weeks, respectively, P < 0.0001 for both). The rate of adverse events was lower in subjects treated with brodalumab compared to subjects treated with FAE (616.4 vs. 1195.8 events per 100 exposure years). No new safety signals were detected for brodalumab. CONCLUSIONS: Brodalumab was associated with rapid and significant improvements in signs and symptoms of moderate-to-severe plaque psoriasis, with a superior efficacy profile to what was observed with FAE in systemic-naïve subjects over 24 weeks.

INTRODUCTION: Biologic switching is common in psoriasis patients with non-response to or adverse events under therapy with a biologic. However, evidence on efficacy of switching between newly approved biologics of similar mode of action is scarce. The objective was to assess the efficacy of treating psoriasis patients with an IL-17-receptor A antagonist after failure of any IL-17A antagonist and to identify predictors of treatment response. METHODS: A retrospective multicenter chart review on psoriasis patients who received brodalumab after failure of ixekizumab or secukinumab therapy was conducted in five German University Medical centers. RESULTS: Overall, 23 patients were identified. PASI75 response to brodalumab was reached by 47.8% (11/23) of all patients at week 12 and at week 24. 3 patients experienced mild adverse events which did not lead to drug discontinuation. CONCLUSIONS: Brodalumab appears to be an efficacious and safe treatment option in psoriasis patients with prior exposure to IL-17A antagonists.

BACKGROUND: Significantly more patients with moderate-to-severe plaque psoriasis treated with the interleukin (IL)-17A inhibitor ixekizumab vs. the IL-23p19 inhibitor guselkumab in the IXORA-R head-to-head trial achieved 100% improvement in Psoriasis Area and Severity Index (PASI 100) at week 12. OBJECTIVES: To compare skin and nail clearance and patient-reported outcomes for ixekizumab vs. guselkumab, up to week 24. METHODS: IXORA-R enrolled adults with moderate-to-severe plaque psoriasis, defined as static Physician's Global Assessment ≥ 3, PASI ≥ 12 and involved body surface area ≥ 10%. Statistical comparisons were performed using the Cochran-Mantel-Haenszel test stratified by pooled site. Time-to-first-event comparisons were performed using Kaplan-Meier analysis, and P-values were generated using adjusted log-rank tests stratified by treatment group. Cumulative days at clinical and patient-reported responses were compared by ancova. The trial was registered with ClinicalTrials.gov (NCT03573323). RESULTS: Of the 1027 patients randomly assigned, 90% completed the trial (465 of 520 ixekizumab and 459 of 507 guselkumab). As early as week 2 and through week 16, more patients on ixekizumab achieved PASI 100 (P < 0·01). At week 24, ixekizumab was noninferior to guselkumab (50% vs. 52%, difference -2·3%), with no statistically significant difference in PASI 100 (P = 0·41). More patients receiving ixekizumab showed completely clear nails at week 24 (52% vs. 31%, P = 0·007). The median time to first PASI 50/75/90 and PASI 100 were 2 and 7·5 weeks shorter, respectively, for patients on ixekizumab vs. guselkumab (P < 0·001). Patients on ixekizumab also had a greater cumulative benefit, with more days at PASI 90 and 100, with Dermatology Life Quality Index of 0 or 1, and itch free (P < 0·05). The frequency of serious adverse events was 3% for each group, with no new safety signals. CONCLUSIONS: Ixekizumab was noninferior to guselkumab in complete skin clearance and superior in clearing nails at week 24. Ixekizumab cleared skin more rapidly in patients with moderate-to-severe plaque psoriasis, with a greater cumulative benefit, than guselkumab. Overall, the safety findings were consistent with the known safety profile for ixekizumab.
