RESUMO
BACKGROUND: Lebrikizumab, a high-affinity IgG4 monoclonal antibody targeting interleukin-13, prevents the formation of the interleukin-4Rα-interleukin-13Rα1 heterodimer receptor signaling complex. METHODS: We conducted two identically designed, 52-week, randomized, double-blind, placebo-controlled, phase 3 trials; both trials included a 16-week induction period and a 36-week maintenance period. Eligible patients with moderate-to-severe atopic dermatitis (adults [≥18 years of age] and adolescents [12 to <18 years of age, weighing ≥40 kg]) were randomly assigned in a 2:1 ratio to receive either lebrikizumab at a dose of 250 mg (loading dose of 500 mg at baseline and week 2) or placebo, administered subcutaneously every 2 weeks. Outcomes for the induction period were assessed up to 16 weeks and are included in this report. The primary outcome was an Investigator's Global Assessment (IGA) score of 0 or 1 (indicating clear or almost clear skin; range, 0 to 4 [severe disease]) with a reduction (indicating improvement) of at least 2 points from baseline at week 16. Secondary outcomes included a 75% improvement in the Eczema Area and Severity Index score (EASI-75 response) and assessments of itch and of itch interference with sleep. Safety was also assessed. RESULTS: In trial 1, the primary outcome was met in 43.1% of 283 patients in the lebrikizumab group and in 12.7% of 141 patients in the placebo group (P<0.001); an EASI-75 response occurred in 58.8% and 16.2%, respectively (P<0.001). In trial 2, the primary outcome was met in 33.2% of 281 patients in the lebrikizumab group and in 10.8% of 146 patients in the placebo group (P<0.001); an EASI-75 response occurred in 52.1% and 18.1%, respectively (P<0.001). Measures of itch and itch interference with sleep indicated improvement with lebrikizumab therapy. The incidence of conjunctivitis was higher among patients who received lebrikizumab than among those who received placebo. Most adverse events during the induction period were mild or moderate in severity and did not lead to trial discontinuation. CONCLUSIONS: In the induction period of two phase 3 trials, 16 weeks of treatment with lebrikizumab was effective in adolescents and adults with moderate-to-severe atopic dermatitis.

BACKGROUND: 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. METHODS: 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). FINDINGS: 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. INTERPRETATION: 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. FUNDING: Galderma.

BACKGROUND: Spesolimab is an anti-interleukin-36 receptor monoclonal antibody approved to treat generalised pustular psoriasis (GPP) flares. We aimed to assess the efficacy and safety of spesolimab for GPP flare prevention. METHODS: This multicentre, randomised, placebo-controlled, phase 2b trial was done at 60 hospitals and clinics in 20 countries. Eligible study participants were aged between 12 and 75 years with a documented history of GPP as per the European Rare and Severe Psoriasis Expert Network criteria, with a history of at least two past GPP flares, and a GPP Physician Global Assessment (GPPGA) score of 0 or 1 at screening and random assignment. Patients were randomly assigned (1:1:1:1) to receive subcutaneous placebo, subcutaneous low-dose spesolimab (300 mg loading dose followed by 150 mg every 12 weeks), subcutaneous medium-dose spesolimab (600 mg loading dose followed by 300 mg every 12 weeks), or subcutaneous high-dose spesolimab (600 mg loading dose followed by 300 mg every 4 weeks) over 48 weeks. The primary objective was to demonstrate a non-flat dose-response curve on the primary endpoint, time to first GPP flare. FINDINGS: From June 8, 2020, to Nov 23, 2022, 157 patients were screened, of whom 123 were randomly assigned. 92 were assigned to receive spesolimab (30 high dose, 31 medium dose, and 31 low dose) and 31 to placebo. All patients were either Asian (79 [64%] of 123) or White (44 [36%]). Patient groups were similar in sex distribution (76 [62%] female and 47 [38%] male), age (mean 40·4 years, SD 15·8), and GPP Physician Global Assessment score. A non-flat dose-response relationship was established on the primary endpoint. By week 48, 35 patients had GPP flares; seven (23%) of 31 patients in the low-dose spesolimab group, nine (29%) of 31 patients in the medium-dose spesolimab group, three (10%) of 30 patients in the high-dose spesolimab group, and 16 (52%) of 31 patients in the placebo group. High-dose spesolimab was significantly superior versus placebo on the primary outcome of time to GPP flare (hazard ratio [HR]=0·16, 95% CI 0·05-0·54; p=0·0005) endpoint. HRs were 0·35 (95% CI 0·14-0·86, nominal p=0·0057) in the low-dose spesolimab group and 0·47 (0·21-1·06, p=0·027) in the medium-dose spesolimab group. We established a non-flat dose-response relationship for spesolimab compared with placebo, with statistically significant p values for each predefined model (linear p=0·0022, emax1 p=0·0024, emax2 p=0·0023, and exponential p=0·0034). Infection rates were similar across treatment arms; there were no deaths and no hypersensitivity reactions leading to discontinuation. INTERPRETATION: High-dose spesolimab was superior to placebo in GPP flare prevention, significantly reducing the risk of a GPP flare and flare occurrence over 48 weeks. Given the chronic nature of GPP, a treatment for flare prevention is a significant shift in the clinical approach, and could ultimately lead to improvements in patient morbidity and quality of life.

BACKGROUND: Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F and IL-17A. This study compared the efficacy and safety of bimekizumab with placebo over 16 weeks in patients with active psoriatic arthritis and previous inadequate response or intolerance to tumour necrosis factor-α (TNFα) inhibitors. METHODS: BE COMPLETE was a phase 3, multicentre, randomised, double-blind, placebo-controlled trial conducted across 92 sites (including hospitals, clinics, and research centres) in 11 countries (Australia, Canada, Czech Republic, Germany, Hungary, Italy, Japan, Poland, Russia, the UK, and the USA). Eligible patients were aged 18 years or older with adult-onset psoriatic arthritis (meeting the Classification Criteria for Psoriatic Arthritis for at least 6 months before screening) with a history of inadequate response or intolerance to treatment with one or two TNFα inhibitors for either psoriatic arthritis or psoriasis. We stratified patients with active psoriatic arthritis by region and previous TNFα inhibitor use. Patients were randomly assigned (2:1) to receive subcutaneous bimekizumab 160 mg every 4 weeks or placebo by an interactive-voice and web-response system on the basis of a predetermined randomisation schedule. The primary endpoint was the proportion of patients with 50% or greater improvement in American College of Rheumatology criteria (ACR50) at week 16 (non-responder imputation). Efficacy analyses were done in the randomised population. The safety analysis set comprised patients who received one or more doses of study treatment. This trial was registered at ClinicalTrials.gov, NCT03896581, and is completed. FINDINGS: Between March 28, 2019, and Feb 14, 2022, 556 patients were screened and 400 patients were randomly assigned to bimekizumab 160 mg every 4 weeks (n=267) or placebo (n=133). The primary and all hierarchical secondary endpoints were met at week 16. 116 (43%) of 267 patients receiving bimekizumab reached ACR50, compared with nine (7%) of 133 patients receiving placebo (adjusted odds ratio [OR] 11·1 [95% CI 5·4-23·0], p<0·0001). 121 (69%) of 176 patients with psoriasis affecting at least 3% body surface area at baseline who received bimekizumab reached 90% or greater improvement in the Psoriasis Area and Severity Index (PASI90), compared with six (7%) of 88 patients who received placebo (adjusted OR 30·2 [12·4-73·9], p<0·0001). Treatment-emergent adverse events up to week 16 were reported in 108 (40%) of 267 patients receiving bimekizumab and 44 (33%) of 132 patients receiving placebo. There were no new safety signals and no deaths. INTERPRETATION: Bimekizumab treatment led to superior improvements in joint and skin efficacy outcomes at week 16 compared with placebo in patients with psoriatic arthritis and inadequate response or intolerance to TNFα inhibitors. The safety profile of bimekizumab was consistent with previous phase 3 studies in patients with plaque psoriasis, and studies of IL-17A inhibitors. FUNDING: UCB Pharma.

BACKGROUND: The oral Janus kinase 1 (JAK1) inhibitor abrocitinib, which reduces interleukin-4 and interleukin-13 signaling, is being investigated for the treatment of atopic dermatitis. Data from trials comparing JAK1 inhibitors with monoclonal antibodies, such as dupilumab, that block interleukin-4 receptors are limited. METHODS: In a phase 3, double-blind trial, we randomly assigned patients with atopic dermatitis that was unresponsive to topical agents or that warranted systemic therapy (in a 2:2:2:1 ratio) to receive 200 mg or 100 mg of abrocitinib orally once daily, 300 mg of dupilumab subcutaneously every other week (after a loading dose of 600 mg), or placebo; all the patients received topical therapy. The primary end points were an Investigator's Global Assessment (IGA) response (defined as a score of 0 [clear] or 1 [almost clear] on the IGA [scores range from 0 to 4], with an improvement of ≥2 points from baseline) and an Eczema Area and Severity Index-75 (EASI-75) response (defined as ≥75% improvement from baseline in the score on the EASI [scores range from 0 to 72]) at week 12. The key secondary end points were itch response (defined as an improvement of ≥4 points in the score on the Peak Pruritus Numerical Rating Scale [scores range from 0 to 10]) at week 2 and IGA and EASI-75 responses at week 16. RESULTS: A total of 838 patients underwent randomization; 226 patients were assigned to the 200-mg abrocitinib group, 238 to the 100-mg abrocitinib group, 243 to the dupilumab group, and 131 to the placebo group. An IGA response at week 12 was observed in 48.4% of patients in the 200-mg abrocitinib group, 36.6% in the 100-mg abrocitinib group, 36.5% in the dupilumab group, and 14.0% in the placebo group (P<0.001 for both abrocitinib doses vs. placebo); an EASI-75 response at week 12 was observed in 70.3%, 58.7%, 58.1%, and 27.1%, respectively (P<0.001 for both abrocitinib doses vs. placebo). The 200-mg dose, but not the 100-mg dose, of abrocitinib was superior to dupilumab with respect to itch response at week 2. Neither abrocitinib dose differed significantly from dupilumab with respect to most other key secondary end-point comparisons at week 16. Nausea occurred in 11.1% of the patients in the 200-mg abrocitinib group and 4.2% of those in the 100-mg abrocitinib group, and acne occurred in 6.6% and 2.9%, respectively. CONCLUSIONS: In this trial, abrocitinib at a dose of either 200 mg or 100 mg once daily resulted in significantly greater reductions in signs and symptoms of moderate-to-severe atopic dermatitis than placebo at weeks 12 and 16. The 200-mg dose, but not the 100-mg dose, of abrocitinib was superior to dupilumab with respect to itch response at week 2. Neither abrocitinib dose differed significantly from dupilumab with respect to most other key secondary end-point comparisons at week 16.

BACKGROUND: Patients with psoriasis require long-term management; therefore, understanding the long-term safety of new treatments, such as bimekizumab (BKZ), is crucial. OBJECTIVES: To evaluate BKZ's 3-year safety profile in patients with moderate-to-severe plaque psoriasis. METHODS: Three years of safety data were pooled from three phase III trials (BE VIVID, BE READY and BE SURE) and their ongoing open-label extension (BE BRIGHT). Treatment-emergent adverse events (TEAEs) are reported using exposure-adjusted incidence rates (EAIRs) per 100 patient-years (PY). RESULTS: In total, 1495 patients received at least one BKZ dose; total BKZ exposure was 3876.4 PY. The overall EAIR of TEAEs was 175.5/100 PY and decreased with longer exposure to BKZ. The most commonly reported TEAEs were nasopharyngitis, oral candidiasis and upper respiratory tract infection (EAIRs of 15.0/100 PY, 10.1/100 PY and 6.5/100 PY, respectively); 99.3% of oral candidiasis events were mild or moderate in severity, none were serious and few led to discontinuation. EAIRs of other TEAEs of interest were low, including serious infections (1.2/100 PY), adjudicated inflammatory bowel disease (0.2/100 PY) and laboratory elevations in aspartate aminotransferase or alanine aminotransferase (> 5 × upper limit of normal: 0.6/100 PY). CONCLUSIONS: In these analyses pooled across 3â years, no new safety signals were observed with longer exposure to BKZ. The vast majority of oral candidiasis events were mild or moderate in severity, as reported previously.

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 1â year in patients with psoriasis. OBJECTIVE: To evaluate deucravacitinib safety and efficacy over 2â 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 6â 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 1â year and 2â 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 2â years than at 1â 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 2â 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 2â 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 1â 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 2â 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 1â year were maintained for up to 2â years in patients receiving deucravacitinib treatment from the start of PSO-1 or PSO-2, or who crossed over from placebo to deucravacitinib at 4â 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.

BACKGROUND: The anti-interleukin-23 antibody guselkumab (GUS) demonstrated favourable week 24 efficacy and safety over fumaric acid esters (FAE) in systemic treatment-naïve patients with moderate-to-severe plaque psoriasis (study part I). OBJECTIVES: To compare, in study part II, the sustainability of treatment responses (weeks 24-32) in GUS- and FAE-treated patients and treatment responses (weeks 32-56) in patients treated with GUS and FAE and in FAE nonresponders switching to GUS; and, in part III, to investigate the maintenance of response through week 100 in patients withdrawn from GUS at week 56. METHODS: At week 0, systemic treatment-naïve patients were randomized 1 : 1 to GUS or FAE as per label. At week 32, patients with a Psoriasis Area and Severity Index (PASI) 75 (≥ 75% improvement in PASI score) response (r) continued assigned treatment (GUSr-GUS; FAEr-FAE), whereas nonresponders (nr) received GUS (FAEnr-GUS; GUSnr-GUS). GUS-treated patients with a week 56 PASI 90 response (≥ 90% improvement in PASI score) were withdrawn (w) and followed until loss of response or week 100. RESULTS: At week 32, 98% (n = 54/55) of GUS- and 41% (n = 14/34) of FAE-treated patients were PASI 75 responders. At week 56, 91%, 50% and 80% of GUSr-GUS, FAEr-FAE and FAEnr-GUS patients, respectively, achieved a PASI 90 response; 72%, 29% and 45%, respectively, achieved a Dermatology Life Quality Index score of 0/1. At week 100, 44 weeks postwithdrawal, 47% (n = 17/36) and 25% (n = 3/12) of GUS-GUSw and FAE-GUSw patients, respectively, maintained a PASI score ≤ 5. Overall, the adverse event and discontinuation rates were lower for GUS than FAE. CONCLUSIONS: In these exploratory analyses, GUS, as a first-line systemic treatment or second-line systemic treatment in FAE nonresponders, was associated with long-term clinical efficacy up to week 100, including a withdrawal period.

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.

BACKGROUND: Atopic dermatitis is a chronic relapsing inflammatory skin disease characterized by intense itch impacting heavily on patients' and caregivers' quality of life. Its clinical presentation is accompanied by a variety of type 2 comorbidities, e.g. asthma, hay fever, food allergies. However, current data on cardiovascular comorbidities are inconsistent. OBJECTIVES: To identify risk of cardiovascular diseases in patients with atopic dermatitis. METHODS: Data from Electronic Health Records (EHRs) of 1,070,965 atopic dermatitis patients and equally propensity score matched controls were retrieved from the US Collaborative Network part of the federated TriNetX network. Hazard ratios for risk of onset of cardiovascular diseases with a prevalence of ≥1% in both cohorts within 20â years after diagnosis were determined. RESULTS: A total of 55 cardiovascular diseases belonging to 8 major cardiovascular groups were identified. Of those, 53 diagnoses displayed a significantly increased risk in atopic dermatitis patients. Different diagnoses of heart failure and heart disease were found most often, followed by valve insufficiencies, arrhythmia, tachycardia, atrial fibrillation, flutter, but also MACE and venous thromboembolism. The individual diagnoses venous insufficiency, atherosclerosis of native arteries of the extremities, and unspecified diastolic (congestive) heart failure displayed highest hazard ratios. CONCLUSION: Atopic dermatitis is associated with an increased risk for multiple cardiovascular diseases.
RESUMO
BACKGROUND: Cancer risk after long-term exposure to interleukin (IL)-23 inhibitors (IL-23i) and IL-17 inhibitors (IL-17i) remains to be delineated. OBJECTIVE: To evaluate the risk of malignancies in patients with psoriasis treated with IL-23i and IL-17i relative to those prescribed tumour necrosis factor inhibitors (TNFi) during the first 5 years following drug initiation. METHODS: A global population-based cohort study included two distinct analyses comparing patients with psoriasis under different therapeutic modalities; (i) new users of IL-17i(n = 15,331) versus TNFi (n = 15,331) and (ii) new users of IL-23i (n = 5832) versus TNFi (n = 5832). RESULTS: Patients prescribed IL-17i experienced a decreased risk of non-Hodgkin lymphoma (NHL; HR, 0.58; 95% CI, 0.40-0.82; p = 0.002), colorectal cancer (HR, 0.68; 95% CI, 0.49-0.95; p = 0.024), hepatobiliary cancer (HR, 0.68; 95% CI, 0.58-0.80; p < 0.001), ovary cancer (HR, 0.48; 95% CI, 0.29-0.81; p = 0.005), melanoma (HR, 0.52; 95% CI, 0.37-0.73; p < 0.001), and basal cell carcinoma (BCC; HR, 0.57; 95% CI, 0.48-0.67; p < 0.001). IL-23i was associated with a reduced risk of NHL (HR, 0.39; 95% CI, 0.19-0.78; p = 0.006), hepatobiliary cancer (HR, 0.44; 95% CI, 0.31-0.62; p < 0.001) and BCC (HR, 0.76; 95% CI, 0.57-0.99; p = 0.046). In a sensitivity analysis comparing patients managed by IL-17i and IL-23i with their biologic-naïve counterparts, these classes were associated with decreased risk of several malignancies. CONCLUSION: IL-17i and IL-23i are associated with decreased risk of several malignancies. These findings should be considered prior to the prescription of biologics.

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.

BACKGROUND: Immune-mediated inflammatory diseases (IMID) can lead to a substantial disease burden for those affected, in particular by the concomitant occurrence of other IMIDs or in the presence of comorbidities. The care of patients with IMIDs is complex and involves various medical disciplines. OBJECTIVE: To describe the burden of disease and the current routine drug treatment of patients with IMID. MATERIAL AND METHODS: The retrospective cross-sectional analysis was based on statutory health insurance claims data from the InGef database. Prevalent patients with psoriasis (Pso), psoriatic arthritis (PsA), spondylarthritis (SpA), rheumatoid arthritis (RA), Crohn's disease (MC), ulcerative colitis (CU), or connective tissue disease were identified among 3,988,695 insured patients in 2018. The concomitant occurrence of different IMIDs and the extent to which patients with IMID are affected by other comorbidities compared to a reference population were investigated. The current routine drug treatment was described based on the use of predefined forms of treatment. RESULTS: In the database 188,440 patients with IMID (4.7%) were identified. Compared to the reference population the prevalence of comorbidities, such as depressive episodes and cardiovascular risk factors was higher in patients with IMID. For MC, CU, RA, and PsA disease-modifying antirheumatic drugs (DMARD) and classical systemic forms of treatment were used most commonly. In Pso, SpA, and connective tissue disease nonsteroidal anti-inflammatory drugs (NSAID) were the most frequently used treatment often in combination with other drugs. CONCLUSION: A considerable number of patients with IMIDs (16.9-27.5%) suffer from different diseases of the IMID group. They are frequently affected by accompanying illnesses and require interdisciplinary medical treatment.

BACKGROUND: Limited data exist on the characteristics of SARS-CoV-2 infections in German patients with psoriasis or psoriasis arthritis (PsA). This study analyses COVID-19 prevalence and severity of symptoms in these patients. PATIENTS AND METHODS: Participants of the German registries PsoBest and CoronaBest were surveyed in February 2022. Descriptive analyses were conducted. RESULTS: 4,818 patients were included in the analysis, mean age of 56.4 years. Positive SARS-CoV-2 tests were reported by 737 (15.3%) patients. The most frequently reported acute symptoms were fatigue (67.3%), cough (58.8%), and headache (58.3%). Longer-lasting symptoms after COVID-19 were reported by 231 of 737 patients after the acute phase. For most patients (92.9%), systemic treatment for their psoriasis or PsA was not modified during the pandemic. Patients positively tested for SARS-CoV-2 were younger on average and had more often changes in the therapy of psoriasis than negatively tested patients (8.5% vs. 5.4%). CONCLUSIONS: In this cohort of patients with psoriasis or PsA undergoing systemic treatment, SARS-CoV-2 infections were common but less frequent than in the general German population. No risk signals for more severe COVID-19 or increased infection rates were observed in the patients. In addition, systemic treatments remained largely unchanged, so that no risks can be attributed to these therapies.

BACKGROUND: Guselkumab has demonstrated favourable safety and efficacy across individual clinical studies in adults with moderate-to-severe plaque psoriasis. OBJECTIVES: To evaluate the safety of guselkumab in patients with psoriasis using pooled data from seven phase II/III studies (X-PLORE, VOYAGE 1, VOYAGE 2, NAVIGATE, ORION, ECLIPSE, Japan registration). METHODS: All studies, except NAVIGATE and ECLIPSE (active comparator-controlled only), included a 16-week placebo-controlled period; X-PLORE, VOYAGE 1 and VOYAGE 2 included both placebo and active controls. In most studies, guselkumab-treated patients received 100-mg subcutaneous injections at week 0, week 4, and then every 8 weeks thereafter. Safety data were summarized for the placebo-controlled period (weeks 0-16) and through the end of the reporting period (up to 5â years). Incidence rates of key safety events were integrated post hoc, adjusted for the duration of follow-up and reported per 100 patient-years (PY). RESULTS: During the placebo-controlled period, 544 patients received placebo (165 PY) and 1220 received guselkumab (378 PY). Through the end of the reporting period, 2891 guselkumab-treated patients contributed 8662 PY of follow-up. During the placebo-controlled period, in the guselkumab and placebo groups, respectively, rates of adverse events (AEs) were 346/100 PY and 341/100 PY, and infections were 95.9/100 PY and 83.6/100 PY. Rates of serious AEs (6.3/100 PY vs. 6.7/100 PY), AEs leading to discontinuation (5.0/100 PY vs. 9.7/100 PY), serious infections (1.1/100 PY vs. 1.2/100 PY), malignancy (0.5 patients/100 PY vs. 0.0 patients/100 PY) and major adverse cardiovascular events (MACE; 0.3/100 PY vs. 0.0/100 PY) were low and comparable between guselkumab and placebo. Through the end of the reporting period, safety event rates were lower than or comparable to the placebo-controlled period in guselkumab-treated patients: AEs, 169/100 PY; infections, 65.9/100 PY; serious AEs, 5.3/100 PY; AEs leading to discontinuation, 1.6/100 PY; serious infections, 0.9/100 PY; malignancy, 0.7/100 PY; and MACE, 0.3/100 PY. There were no cases of Crohn disease, ulcerative colitis, opportunistic infection or active tuberculosis related to guselkumab. CONCLUSIONS: In this comprehensive analysis of 2891 guselkumab-treated patients with psoriasis followed for up to 5â years (8662 PY), guselkumab demonstrated favourable safety, consistent with previous reports. Safety event rates in guselkumab-treated patients were similar to those observed with placebo and were consistent throughout long-term treatment.

BACKGROUND: BE SURE 1-year results demonstrated the superior efficacy of bimekizumab compared with adalimumab with no unexpected safety findings. OBJECTIVES: To provide efficacy and safety data over 2 years of bimekizumab treatment compared with adalimumab from BE SURE and the BE BRIGHT open-label extension (OLE) in patients with moderate-to-severe plaque psoriasis. METHODS: The 56-week double-blinded BE SURE phase III randomized controlled trial randomized patients 1 : 1 : 1 to bimekizumab 320â mg every 4 weeks (Q4W), bimekizumab 320â mg Q4W to week 16 then every 8 weeks (Q8W), or adalimumab 40â mg every 2 weeks to week 24 then bimekizumab 320â mg Q4W. After completing BE SURE, patients could enter the ongoing BE BRIGHT OLE, with possible dosing adjustments based on Psoriasis Area and Severity Index (PASI). The primary outcome in BE BRIGHT was incidence of treatment-emergent adverse events (TEAEs); safety data are reported by study period through week 104. Efficacy data are reported for the intention-to-treat population through week 104 by initial randomization group, with ≥ 90% improvement from baseline PASI (PASI 90) and 100% improvement (PASI 100) as key outcomes. RESULTS: Of the patients randomized to bimekizumab, 158 were assigned to Q4W, and 161 to Q4W/Q8W. At week 104, PASI 90 was achieved by 91.2% and 89.7%, and PASI 100 was achieved by 72.3% and 68.1%, for Q4W and Q4W/Q8W, respectively; comparable to week 16 results. Among the 159 patients randomized to adalimumab, responses rapidly and substantially increased after the week 24 bimekizumab switch; at week 104, 96.9% and 70.2% of patients achieved PASI 90 and PASI 100 respectively. Through weeks 24-104, the three most common TEAEs in any bimekizumab-treated group were nasopharyngitis, oral candidiasis and upper respiratory tract infection. Rates of serious TEAEs were low. CONCLUSIONS: Clinical responses observed through week 16 of BE SURE in patients randomized to bimekizumab were sustained through 104 weeks of treatment, regardless of Q4W or Q8W maintenance dosing. Response rates were also sustained through week 104 in patients who switched from adalimumab to bimekizumab at week 24, and were similar to those observed in the bimekizumab groups. Bimekizumab was well tolerated with no new safety signals.

BACKGROUND: Bimekizumab is a monoclonal IgG1 antibody that inhibits interleukin-17A/F. Bimekizumab is more efficacious than secukinumab over 1 year in the treatment of psoriasis. OBJECTIVE: Evaluate the safety and efficacy of bimekizumab through 2 years in patients with moderate to severe plaque psoriasis. METHODS: The BE RADIANT phase 3b randomized controlled trial consisted of a 48-week double-blinded period, where patients received bimekizumab (320 mg every 4 or 8 weeks) or secukinumab (300 mg weekly to Week 4, then every 4 weeks), and an open-label extension (OLE). From Week 48, all patients received bimekizumab in the OLE. RESULTS: At Week 48, more patients achieved complete skin clearance (PASI 100; modified non-responder imputation) with bimekizumab than secukinumab (74.8% vs 52.8%). PASI 100 responses were maintained to Week 96 in continuous bimekizumab patients (70.8%); patients who switched from secukinumab to bimekizumab had increased rates at Week 96 (76.6%). The most common adverse events were: nasopharyngitis, oral candidiasis, and urinary tract infection. Safety data were consistent with the known safety profile of bimekizumab. LIMITATIONS: Limited racial diversity; overlap with the COVID-19 pandemic. CONCLUSIONS: High PASI 100 responses achieved with bimekizumab over 48 weeks were sustained through Week 96; secukinumab patients who switched to bimekizumab achieved similar responses by Week 96.

BACKGROUND: Deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, inhibits cytokine signaling in psoriasis pathogenesis. OBJECTIVE: The objective of this study was to demonstrate deucravacitinib superiority versus placebo and apremilast in moderate to severe plaque psoriasis based on ≥75% reduction from baseline in Psoriasis Area and Severity Index and a static Physician's Global Assessment score of 0 (clear) or 1 (almost clear) with a ≥2-point improvement from baseline at week 16. METHODS: POETYK psoriasis second trial (NCT03611751), a 52-week, double-blinded, phase 3 trial, randomized patients 2:1:1 to deucravacitinib 6 mg every day (n = 511), placebo (n = 255), or apremilast 30 mg twice a day (n = 254). RESULTS: At week 16, significantly more deucravacitinib-treated patients versus placebo and apremilast patients achieved ≥75% reduction from baseline in Psoriasis Area and Severity Index (53.0% vs 9.4% and 39.8%; P < .0001 vs placebo; P = .0004 vs apremilast) and static Physician's Global Assessment score of 0 or 1 (49.5% vs 8.6% and 33.9%; P < .0001 for both). Efficacy was maintained until week 52 with continuous deucravacitinib. The most frequent adverse event with deucravacitinib was nasopharyngitis. Serious adverse events and discontinuations due to adverse events were infrequent. No clinically meaningful changes were observed in laboratory parameters. LIMITATIONS: The study duration was 1 year. CONCLUSION: Deucravacitinib demonstrated superiority versus placebo and apremilast and was well tolerated in adults with moderate to severe plaque psoriasis.

BACKGROUND: Effective, well-tolerated oral psoriasis treatments are needed. OBJECTIVE: To compare the efficacy and safety of deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, versus placebo and apremilast in adults with moderate to severe plaque psoriasis. METHODS: Participants were randomized 2:1:1 to deucravacitinib 6 mg every day (n = 332), placebo (n = 166), or apremilast 30 mg twice a day (n = 168) in the 52-week, double-blinded, phase 3 POETYK PSO-1 trial (NCT03624127). Coprimary end points included response rates for ≥75% reduction from baseline in Psoriasis Area and Severity Index (PASI 75) and static Physician's Global Assessment score of 0 or 1 (sPGA 0/1) with deucravacitinib versus placebo at week 16. RESULTS: At week 16, response rates were significantly higher with deucravacitinib versus placebo or apremilast for PASI 75 (194 [58.4%] vs 21 [12.7%] vs 59 [35.1%]; P < .0001) and sPGA 0/1 (178 [53.6%] vs 12 [7.2%] vs 54 [32.1%]; P < .0001). Efficacy improved beyond week 16 and was maintained through week 52. Adverse event rates with deucravacitinib were similar to those with placebo and apremilast. LIMITATIONS: One-year duration, limited racial diversity. CONCLUSION: Deucravacitinib was superior to placebo and apremilast across multiple efficacy end points and was well tolerated in moderate to severe plaque psoriasis.

BACKGROUND: Vitiligo is a chronic autoimmune disorder characterized by depigmented patches of the skin. OBJECTIVE: To evaluate the efficacy and safety of ritlecitinib, an oral JAK3 (Janus kinase)/TEC (tyrosine kinase expressed in hepatocelluar carcinoma) inhibitor, in patients with active nonsegmental vitiligo in a phase 2b trial (NCT03715829). METHODS: Patients were randomized to once-daily oral ritlecitinib ± 4-week loading dose (200/50 mg, 100/50 mg, 30 mg, or 10 mg) or placebo for 24 weeks (dose-ranging period). Patients subsequently received ritlecitinib 200/50 mg daily in a 24-week extension period. The primary efficacy endpoint was percent change from baseline in Facial-Vitiligo Area Scoring Index at week 24. RESULTS: A total of 364 patients were treated in the dose-ranging period. Significant differences from placebo in percent change from baseline in Facial-Vitiligo Area Scoring Index were observed for the ritlecitinib 50 mg groups with (-21.2 vs 2.1; P < .001) or without (-18.5 vs 2.1; P < .001) a loading dose and ritlecitinib 30 mg group (-14.6 vs 2.1; P = .01). Accelerated improvement was observed after treatment with ritlecitinib 200/50 mg in the extension period (n = 187). No dose-dependent trends in treatment-emergent or serious adverse events were observed across the 48-week treatment. LIMITATIONS: Patients with stable vitiligo only were excluded. CONCLUSIONS: Oral ritlecitinib was effective and well tolerated over 48 weeks in patients with active nonsegmental vitiligo.
