Background Secukinumab, a fully human immunoglobulin G1-kappa monoclonal antibody that directly inhibits interleukin (IL)-17A, has been shown to have robust efficacy in the treatment of moderate-to-severe psoriasis (PsO), psoriatic arthritis (PsA), and ankylosing spondylitis (AS) demonstrating a rapid onset of action and sustained long-term clinical responses with a consistently favorable safety profile in multiple Phase 2 and 3 trials. Here, we report longer-term pooled safety and tolerability data for secukinumab across three indications (up to 5 years of treatment in PsO and PsA; up to 4 years in AS). Methods The integrated clinical trial safety dataset included data pooled from 21 randomized controlled clinical trials of secukinumab 300 or 150 or 75 mg in PsO (14 Phase 3 trials and 1 Phase 4 trial), PsA (3 Phase 3 trials), and AS (3 Phase 3 trials), along with post-marketing safety surveillance data with a cut-off date of June 25, 2017. Adverse events (AEs) were reported as exposure-adjusted incident rates (EAIRs) per 100 patient-years. Analyses included all patients who received ≥ 1 dose of secukinumab. Results A total of 5181, 1380, and 794 patients from PsO, PsA, and AS clinical trials representing secukinumab exposures of 10,416.9, 3866.9, and 1943.1 patient-years, respectively, and post-marketing data from patients with a cumulative exposure to secukinumab of ~ 96,054 patient-years were included in the analysis. The most frequent AE was upper respiratory tract infection. EAIRs across PsO, PsA, and AS indications were generally low for serious infections (1.4, 1.9, and 1.2, respectively), Candida infections (2.2, 1.5, and 0.7, respectively), inflammatory bowel disease (0.01, 0.05, and 0.1, respectively), and major adverse cardiac events (0.3, 0.4, and 0.6, respectively). No cases of tuberculosis reactivation were reported. The incidence of treatment-emergent anti-drug antibodies was low with secukinumab across all studies, with no discernible loss of efficacy, unexpected alterations in pharmacokinetics, or association with immunogenicity-related AEs. Conclusions Secukinumab demonstrated a favorable safety profile over long-term treatment in patients with PsO, PsA, and AS. This comprehensive assessment demonstrated that the safety profile of secukinumab was consistent with previous reports in patients with PsO, PsA, and AS, supporting its long-term use in these chronic conditions.

ObjectivesTo compare efficacy and safety of ixekizumab (IXE) to adalimumab (ADA) in biological disease-modifying antirheumatic drug-naïve patients with both active psoriatic arthritis (PsA) and skin disease and inadequate response to conventional synthetic disease-modifying antirheumatic drug (csDMARDs).MethodsPatients with active PsA were randomised (1:1) to approved dosing of IXE or ADA in an open-label, head-to-head, blinded assessor clinical trial. The primary objective was to evaluate whether IXE was superior to ADA at week 24 for simultaneous achievement of a ≥50% improvement from baseline in the American College of Rheumatology criteria (ACR50) and a 100% improvement from baseline in the Psoriasis Area and Severity Index (PASI100). Major secondary objectives, also at week 24, were to evaluate whether IXE was: (1) non-inferior to ADA for achievement of ACR50 and (2) superior to ADA for PASI100 response. Additional PsA, skin, treat-to-target and quality-of-life outcome measures were assessed at week 24.ResultsThe primary efficacy endpoint was met (IXE: 36%, ADA: 28%; p=0.036). IXE was non-inferior for ACR50 response (IXE: 51%, ADA: 47%; treatment difference: 3.9%) and superior for PASI100 response (IXE: 60%, ADA: 47%; p=0.001). IXE had greater response versus ADA in additional PsA, skin, nail, treat-to-target and quality-of-life outcomes. Serious adverse events were reported in 8.5% (ADA) and 3.5% (IXE) of patients.ConclusionsIXE was superior to ADA in achievement of simultaneous improvement of joint and skin disease (ACR50 and PASI100) in patients with PsA and inadequate response to csDMARDs. Safety and tolerability for both biologicals were aligned with established safety profiles.

Risankizumab is a humanised IgG1 monoclonal antibody that binds to the p19 subunit of interleukin-23, inhibiting this key cytokine and its role in psoriatic inflammation. We aimed to assess the efficacy and safety of risankizumab compared with placebo or ustekinumab in patients with moderate-to-severe chronic plaque psoriasis. UltIMMa-1 and UltIMMa-2 were replicate phase 3, randomised, double-blind, placebo-controlled and active comparator-controlled trials done at 139 sites in Australia, Austria, Belgium, Canada, Czech Republic, France, Germany, Japan, Mexico, Poland, Portugal, South Korea, Spain, and the USA. Eligible patients were 18 years or older, with moderate-to-severe chronic plaque psoriasis. In each study, patients were stratified by weight and previous exposure to tumour necrosis factor inhibitor and randomly assigned (3:1:1) by use of interactive response technology to receive 150 mg risankizumab, 45 mg or 90 mg ustekinumab (weight-based per label), or placebo. Following the 16-week double-blind treatment period (part A), patients initially assigned to placebo switched to 150 mg risankizumab at week 16; other patients continued their originally randomised treatment (part B, double-blind, weeks 16–52). Study drug was administered subcutaneously at weeks 0 and 4 during part A and at weeks 16, 28, and 40 during part B. Co-primary endpoints were proportions of patients achieving a 90% improvement in the Psoriasis Area Severity Index (PASI 90) and a static Physician's Global Assessment (sPGA) score of 0 or 1 at week 16 (non-responder imputation). All efficacy analyses were done in the intention-to-treat population. These trials are registered with ClinicalTrials.gov, numbers NCT02684370 (UltIMMa-1) and NCT02684357 (UltIMMa-2), and have been completed. Between Feb 24, 2016, and Aug 31, 2016, 506 patients in UltIMMa-1 were randomly assigned to receive 150 mg risankizumab (n=304), 45 mg or 90 mg ustekinumab (n=100), or placebo (n=102). Between March 1, 2016, and Aug 30, 2016, 491 patients in UltIMMa-2 were randomly assigned to receive 150 mg risankizumab (n=294), 45 mg or 90 mg ustekinumab (n=99), or placebo (n=98). Co-primary endpoints were met for both studies. At week 16 of UltIMMa-1, PASI 90 was achieved by 229 (75·3%) patients receiving risankizumab versus five (4·9%) receiving placebo (placebo-adjusted difference 70·3% [95% CI 64·0–76·7]) and 42 (42·0%) receiving ustekinumab (ustekinumab-adjusted difference 33·5% [22·7–44·3]; p<0·0001 vs placebo and ustekinumab). At week 16 of UltIMMa-2, PASI 90 was achieved by 220 (74·8%) patients receiving risankizumab versus two (2·0%) receiving placebo (placebo-adjusted difference 72·5% [95% CI 66·8–78·2]) and 47 (47·5%) receiving ustekinumab (ustekinumab-adjusted difference 27·6% [16·7–38·5]; p<0·0001 vs placebo and ustekinumab). In UltIMMa-1, sPGA 0 or 1 at week 16 was achieved by 267 (87·8%) patients receiving risankizumab versus eight (7·8%) receiving placebo (placebo-adjusted difference 79·9% [95% CI 73·5–86·3]) and 63 (63·0%) receiving ustekinumab (ustekinumab-adjusted difference 25·1% [15·2–35·0]; p<0·0001 vs placebo and ustekinumab). In UltIMMa-2, 246 (83·7%) patients receiving risankizumab versus five (5·1%) receiving placebo (placebo-adjusted difference 78·5% [95% CI 72·4–84·5]) and 61 (61·6%) receiving ustekinumab achieved sPGA 0 or 1 at week 16 (ustekinumab-adjusted difference 22·3% [12·0–32·5]; p<0·0001 vs placebo and ustekinumab). The frequency of treatment-emergent adverse events in UltIMMa-1 and UltIMMa-2 was similar across risankizumab (part A: 151 [49·7%] of 304 and 134 [45·6%] of 294; part B: 182 [61·3%] of 297 and 162 [55·7%] of 291), placebo (part A: 52 [51·0%] of 102 and 45 [45·9%] of 98), ustekinumab (part A: 50 [50·0%] of 100 and 53 [53·5%] of 99; part B: 66 [66·7%] of 99 and 70 [74·5%] of 94), and placebo to risankizumab (part B: 65 [67·0%] of 97 and 61 [64·9%] of 94) treatment groups throughout the study duration. Risankizumab showed superior efficacy to both placebo and ustekinumab in the treatment of moderate-to-severe plaque psoriasis. Treatment-emergent adverse event profiles were similar across treatment groups and there were no unexpected safety findings. AbbVie and Boehringer Ingelheim.

In a phase 2 trial involving 166 patients with moderate-to-severe plaque psoriasis, risankizumab, a humanized monoclonal antibody that selectively inhibits IL-23, achieved clinical response superior to that achieved with ustekinumab, an IL-12 and IL-23 inhibitor. Psoriasis is a chronic immune-mediated inflammatory skin disease that occurs in 2% of adults; it has a substantial effect on quality of life and is associated with obesity, hypertension, diabetes mellitus, hypercholesterolemia, and the metabolic syndrome. 1 – 4 The proinflammatory cytokine interleukin-23 is thought to play a pivotal role in the pathogenesis of psoriasis by inducing and maintaining T helper (Th) 17 cells, Th22 cells, innate lymphoid cells, and the effector cytokines interleukin-17, interleukin-22, and tumor necrosis factor (TNF) α. 5 – 9 Interleukin-23 is composed of two subunits, p19 and p40. The p19 subunit is unique to interleukin-23, whereas the p40 subunit . . .

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. 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. 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. 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.

In two trials in patients with moderate-to-severe plaque psoriasis, the anti–interleukin-17A monoclonal antibody secukinumab was more effective than placebo and etanercept. Infectious complications occurred more often with secukinumab than with placebo. Psoriasis is a chronic, immune-mediated inflammatory skin disease that is associated with substantial impairment of physical and psychological quality of life. 1 , 2 Our understanding of the pathogenesis of psoriasis was advanced by the discovery of the class of type 17 helper T (Th17) cells, which regulates innate and adaptive immunity. The proinflammatory cytokine interleukin-17A is the primary effector of Th17 cells, but it is also produced by other cell types in psoriatic lesions, including γδ T cells, neutrophils, and possibly mast cells. 3 – 7 Interleukin-17A stimulates keratinocytes to secrete chemokines and other proinflammatory mediators that recruit additional inflammatory cells, including neutrophils, . . .

Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A. This study investigated the efficacy and safety of bimekizumab in patients with moderate to severe plaque psoriasis, the effects of treatment withdrawal, and two maintenance dosing schedules over 56 weeks. BE READY was a phase 3, multicentre, randomised, double-blind, placebo-controlled trial done at 77 sites (hospitals, clinics, private doctor's practices, and dedicated clinical research centres) in nine countries across Asia, Australia, Europe, and North America. Adult patients aged 18 years or older with moderate to severe plaque psoriasis were stratified by region and previous biologic exposure, and randomly assigned (4:1) to receive bimekizumab 320 mg every 4 weeks or placebo every 4 weeks by use of interactive response technology. Coprimary endpoints were the proportion of patients achieving 90% or greater improvement from baseline in the Psoriasis Area Severity Index (PASI90) and the proportion of patients achieving a score of 0 (clear) or 1 (almost clear) on the five-point Investigator's Global Assessment (IGA) scale at week 16 (non-responder imputation). Bimekizumab-treated patients achieving PASI90 at week 16 were re-allocated (1:1:1) to receive bimekizumab 320 mg every 4 weeks, every 8 weeks, or placebo for weeks 16–56. Efficacy analyses were done in the intention-to-treat population; the safety analysis set comprised all patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov (NCT03410992), and is now completed. Between Feb 5, 2018, and Jan 7, 2020, 435 patients were randomly assigned to receive either bimekizumab 320 mg every 4 weeks (n=349) or placebo every 4 weeks (n=86). Coprimary endpoints were met: at week 16, 317 (91%) of 349 patients receiving bimekizumab 320 mg every 4 weeks achieved PASI90, compared with one (1%) of 86 patients receiving placebo (risk difference 89·8 [95% CI 86·1–93·4]; p<0·0001); and 323 (93%) of 349 patients receiving bimekizumab 320 mg every 4 weeks achieved an IGA score of 0 or 1 versus one (1%) of 86 patients receiving placebo (risk difference 91·5 [95% CI 88·0–94·9]; p<0·0001). Responses were maintained through to week 56 with bimekizumab 320 mg every 8 weeks and every 4 weeks. Treatment-emergent adverse events in the initial treatment period (up to week 16) were reported in 213 (61%) of 349 patients receiving bimekizumab 320 mg every 4 weeks and 35 (41%) of 86 patients receiving placebo every 4 weeks. From week 16 to week 56, treatment-emergent adverse events were reported in 78 (74%) of 106 patients receiving bimekizumab 320 mg every 4 weeks, 77 (77%) of 100 patients receiving bimekizumab 320 mg every 8 weeks, and 72 (69%) of 105 patients receiving placebo. Bimekizumab showed high levels of response, which were durable over 56 weeks, with both maintenance dosing schedules (every 4 weeks and every 8 weeks). Moreover, bimekizumab was well tolerated, with no unexpected safety findings. Data presented here further support the therapeutic value of bimekizumab and inhibition of IL-17F in addition to IL-17A for patients with moderate to severe plaque psoriasis. UCB Pharma.

In a randomized trial involving patients with the rare but disabling disorder generalized pustular psoriasis, the anti–interleukin-36 monoclonal antibody spesolimab greatly curtailed disease activity as compared with placebo over a period of 1 week. Systemic drug reactions and infections occurred with spesolimab.

In two phase 3 studies, the anti–interleukin-17 receptor A monoclonal antibody brodalumab was more effective than placebo or ustekinumab in patients with moderate-to-severe psoriasis. Adverse events associated with brodalumab included neutropenia and candida infections. Psoriasis is an inflammatory skin disease that occurs in 2 to 3% of the worldwide population. 1 , 2 Despite the availability of several therapies, many patients remain untreated, do not have an adequate response, or have treatment-related toxic effects. 3 Interleukin-17 cytokines have been implicated in the pathogenesis of psoriasis. Genomewide association studies have linked interleukin-17 pathway–related genes with psoriasis, 4 , 5 and interleukin-17 mRNA levels are higher in psoriatic lesions than in normal skin. 6 , 7 Numbers of type 17 helper T cells are increased in psoriatic lesions and are stimulated by interleukin-23 to release interleukin-17 cytokines. 8 Interleukin-17 cytokines, which include interleukin-17A, interleukin-17C, . . .

In two identical trials of treatment for psoriasis with the topical aryl hydrocarbon receptor–modulating agent tapinarof, clearance or near-clearance of lesions occurred in a larger proportion of patients who used tapinarof cream than of those who used placebo. Side effects included folliculitis, contact dermatitis, and headache.
