Show moreObjective. To report safety and efficacy of ixekizumab (IXE) from the COAST program at 3 years, including 1 year from the originating studies (COAST-V, COAST-W, and COAST-X), and 2 years from COAST-Y.Methods. In COAST-Y, patients continued with the dose received at the end of the originating study at week 52: 80 mg IXE either every 4 weeks (Q4W) or every 2 weeks (Q2W). Placebo-treated patients from COAST-X received IXE Q4W in COAST-Y. Starting at week 116 (week 64 of COAST-Y), patients receiving IXE Q4W could be escalated to Q2W. Safety for patients receiving >= 1 dose of IXE and efficacy for patients receiving >= 1 dose of IXE Q4W was assessed. Data are summarized as observed.Results. For the 932 patients who received >= 1 dose of IXE (Q2W or Q4W) through 3 years, treatment-emergent adverse events (TEAEs) occurred at an incidence rate (IR) of 38.0 per 100 patient-years (PYs). The most frequently reported were infections (IR 25.7 per 100 PYs) and injection site reactions (IR 7.4 per 100 PYs); the majority of TEAEs were mild or moderate in severity. In total, 7.1% of TEAEs led to discontinuation (IR 3.1 per 100 PYs). All patient groups receiving IXE Q4W assessed through 3 years saw sustained improvements in Ankylosing Spondylitis Disease Activity Score, clinically important improvement, and other efficacy end points.Conclusion. The 3-year safety profile of IXE in the COAST program is consistent with the previously established long-term safety profile. IXE Q4W provided sustained improvement of disease activity in patients who received treatment through 3 years.

Show moreBackground: Guselkumab, a fully human monoclonal antibody targeting the interleukin (IL)-23p19 subunit, is approved to treat adults with active psoriatic arthritis (PsA). In the Phase 3 DISCOVER-2 trial of 739 bilogico-naive patients with active PsA, guselkumab 100 mg resulted in less radiographic progression, assessed via change from baseline in PsA-modified van der Heijde-Sharp (vdH-S) score, compared with placebo at week (W) 24 when given at W0, W4, and then every 4 weeks (Q4W) or Q8W. The least squares mean differences from placebo were-0.66 for guselkumab Q4W (p=0.011) and-0.43 for guselkumab Q8W (p=0.072). Reports suggest baseline C-reactive protein (CRP) and joint erosions are strongly prognostic of poor outcomes, especially radiographic progression, in PsA patients. We designed a trial (APEX) to further assess the effect of guselkumab on radiographic progression in patients with active PsA and risk factors for radiographic progression. Methods: Patients are eligible for APEX if they have had PsA for >= 6 months and active disease (> 3 swollen and >= 3 tender joints, CRP > 0.3 mg/dL) despite prior therapy with conventional synthetic disease-modifying antirheu-matic drugs, apremilast, and/or nonsteroidal anti-inflammatory drugs, with >= 2 joints with erosions on baseline radiographs (hands and feet). The primary and major secondary endpoints are the proportion of patients achieving >= 20% improvement in American College of Rheumatology response criteria (ACR20) response at W24 and change from baseline at W24 in PsA-modified vdH-S score, respectively. Sample sizes of 350/250/350 for guselkumab Q8W/ guselkumab Q4W/placebo are expected to provide > 99% power to detect significant differences in W24 ACR20 response rates for each guselkumab group vs placebo, as well as >= 90% (Q4W vs placebo) and >= 80% (Q8W vs placebo) power to detect a significant difference in PsA-modified vdH-S score change at W24. A Cochran-Mantel-Haen-szel test and analysis of covariance will compare treatment efficacy for the primary and major secondary endpoints, respectively. Discussion: DISCOVER-2 findings informed the design of APEX, a Phase 3b study intended to further evaluate the impact of guselkumab in patients with active PsA and known risk factors for radiographic progression.

Show moreObjective To assess long-term efficacy and safety of guselkumab, an interleukin-23 p19 subunit (IL-23p19) inhibitor, in patients with active psoriatic arthritis (PsA) from the phase III DISCOVER-2 trial. Methods In the DISCOVER-2 trial, patients with active PsA (>= 5 swollen joints and >= 5 tender joints; C-reactive protein level >= 0.6 mg/dl) despite prior nonbiologic therapy were randomized to receive the following: guselkumab 100 mg every 4 weeks; guselkumab 100 mg at weeks 0 and 4 and then every 8 weeks; or placebo with crossover to guselkumab 100 mg every 4 weeks, beginning at week 24. Efficacy assessments included American College of Rheumatology >= 20%/50%/70% improvement criteria (ACR20/50/70), Investigator's Global Assessment (IGA) of psoriasis score of 0 (indicating complete skin clearance), resolution of enthesitis (Leeds Enthesitis Index) and dactylitis (Dactylitis Severity Score), and changes in the Sharp/van der Heijde modified radiographic scores for PsA. Clinical data (imputed as no response/no change from baseline if missing) and observed radiographic data were summarized through week 100; safety assessments continued through week 112. Results Of the 739 randomized and treated patients, 652 (88%) completed treatment through week 100. Across groups of guselkumab-treated patients (including those in the placebo-guselkumab crossover group), the following findings at week 100 indicated that amelioration of arthritis signs/symptoms and extraarticular manifestations was durable through 2 years: ACR20 response (68-76%), ACR50 response (48-56%), ACR70 response (30-36%), IGA score of 0 (55-67%), enthesitis resolution (62-70%), and dactylitis resolution (72-83%). Mean changes in the Sharp/van der Heijde modified score for PsA from weeks 52 to week 100 (range 0.13-0.75) indicated that the low rates of radiographic progression observed among guselkumab-treated patients at earlier time points extended through week 100. Through week 112, 8% (5.8 per 100 patient-years) and 3% (1.9 per 100 patient-years) of the 731 guselkumab-treated patients had a serious adverse event or serious infection, respectively; 1 death occurred (road traffic accident). Conclusion In biologic-naive PsA patients, guselkumab provided durable improvements in multiple disease domains with no unexpected safety findings through 2 years. Show less

Show moreObjective Guselkumab, a human monoclonal antibody specific to interleukin-23p19, demonstrated efficacy and safety versus placebo through week 24 of the phase III DISCOVER-2 trial in biologic-naive patients with psoriatic arthritis (PsA). Here we report 1-year DISCOVER-2 findings.Methods Adults with active PsA (>= 5 swollen and >= 5 tender joints; C-reactive protein level >= 0.6 mg/dl) despite standard nonbiologic treatment were randomized to receive subcutaneous injections of guselkumab 100 mg every 4 weeks, guselkumab 100 mg at week 0, week 4 and every 8 weeks thereafter, or placebo with crossover to guselkumab 100 mg every 4 weeks at week 24. We primarily evaluated clinical efficacy through week 52 by imputing missing data (nonresponse for categorical end points; no change/using multiple imputation for continuous end points). Observed radiographic scores and adverse events (AEs) were summarized.Results Of 739 randomized, treated patients, 93% completed week 52. The proportions of patients in whom a >= 20% improvement from baseline in American College of Rheumatology criteria (ACR20) was achieved were maintained after week 24, reaching 71% (173 of 245) and 75% (185 of 248) for patients randomized to receive treatment every 4 weeks or every 8 weeks, respectively, by week 52. The proportions of patients in whom ACR50/ACR70 and skin responses, minimal or very low disease activity, and dactylitis or enthesitis resolution were achieved at week 24 were also maintained through week 52. Further, low levels of radiographic progression, along with improvements in physical function and health-related quality of life, were sustained through week 52 with continued guselkumab treatment. Few patients experienced serious infections through week 52, with no evidence of a dosing regimen response or increase from weeks 0-24 (4 of 493 [0.8%]) to weeks 24-52 (3 of 493 [0.6%]) among guselkumab-randomized patients. No patient developed an opportunistic infection or died.Conclusion In biologic-naive PsA patients, guselkumab provided sustained improvements across diverse manifestations and maintained a favorable risk-benefit profile through week 52.

Show moreObjective Secukinumab provided sustained efficacy, low radiographic progression and consistent safety over 52 weeks in patients with psoriatic arthritis (PsA) in the FUTURE 5 study. Here, we report 2-year (end-of-study) results from this study.Methods Adults with active PsA were randomised 2:2:2:3 to receive subcutaneous secukinumab 300 mg load (300 mg), 150 mg load (150 mg), 150 mg no load or placebo at baseline; weeks 1, 2, 3 and 4; and every 4 weeks thereafter. Secukinumab could be escalated from 150 mg to 300 mg starting at week 52, if active signs of disease were observed based on physician's assessment. Assessments at week 104 (2 years) included clinical end points and radiographic damage (mean change in van der Heijde-modified total Sharp score (vdH-mTSS)). Safety analysis included all patients who received >= 1 dose of study medication.Results Of the 996 patients randomised, 783 patients (78.6%) completed 2 years of treatment. Improvement in clinical end points was sustained through 2 years. The vdH-mTSS (mean change (SD)) was 0.10 (1.74; 300 mg), 0.52 (2.66; 150 mg) and 0.41 (2.20; 150 mg no load) at 2 years. The proportion of patients with no radiographic progression (change from baseline in vdH-mTSS <= 0.5) at 2 years was 89.5% (300 mg), 82.3% (150 mg) and 81.1% (150 mg no load).Conclusion Secukinumab with and without loading regimen provided sustained clinical efficacy and low radiographic progression through 2 years in patients with PsA. No new safety findings were reported. Show less

Show moreObjective. To evaluate the effect of secukinumab on radiographic progression through 52 weeks in patients with PsA from the FUTURE 5 study.Methods. Patients with active PsA, stratified by prior anti-TNF use (naive or inadequate response), were randomized to s.c. secukinumab 300 mg load (300 mg), 150 mg load (150 mg), 150 mg no load regimens or placebo at baseline, at weeks 1, 2 and 3 and every 4 weeks starting at week 4. Radiographic progression was assessed by change in van der Heijde-modified total Sharp score (vdH-mTSS; mean of two readers). Statistical analysis used a linear mixed-effects model (random slope) at weeks 24 and 52, and observed data at week 52. Assessments at week 52 included additional efficacy endpoints (non-responders imputation and mixed-effects models for repeated measures) and safety.Results.The majority (86.6%) of patients completed 52 weeks of treatment. The proportion of patients with no radiographic progression (change from baseline in vdH-mTSS 0.5) was 91.8, 85.2 and 87.2% in 300, 150 and 150 mg no load groups, respectively, at week 52. The change in vdH-mTSS from baseline to week 52 using random slope [mean change (s.e.)] was -0.18 (0.17), 0.11 (0.18) and -0.20 (0.18) in 300, 150 and 150 mg no load groups, respectively; the corresponding observed data [mean change (s.d.)] was -0.09 (1.02), 0.13 (1.39) and 0.21 (1.15). Clinical efficacy endpoints were sustained, and no new or unexpected safety signals were reported through 52 weeks.Conclusion. Secukinumab 300 and 150 mg with or without s.c. loading regimen provided sustained low rates of radiographic progression through 52 weeks of treatment. Show less

Show moreBackground The interleukin-23 (IL-23)/T-helper 17 cell pathway is implicated in psoriatic arthritis pathogenesis. Guselkumab, an IL-23 inhibitor that specifically binds the IL-23 p19 subunit, significantly and safely improved psoriatic arthritis in a phase 2 study. DISCOVER-2 was a phase 3 trial to assess guselkumab in biologic-naive patients with psoriatic arthritis.Methods This phase 3, double-blind, placebo-controlled study was done at 118 sites in 13 countries across Asia, Europe, and North America. We enrolled biologic-naive patients with active psoriatic arthritis (at least five swollen joints, at least five tender joints, and C-reactive protein =0.6 mg/dL) despite standard therapies. Patients were randomly assigned (1:1:1, computer-generated permuted blocks; stratified by baseline disease-modifying antirheumatic drug use and C-reactive protein concentration) to subcutaneous injections of guselkumab 100 mg every 4 weeks; guselkumab 100 mg at weeks 0, 4, then every 8 weeks; or placebo. The primary endpoint was American College of Rheumatology 20% improvement (ACR20) response at week 24 in all patients per assigned treatment group. Safety was assessed in all patients per treatment received. This trial is registered at ClinicalTrials.gov, NCT03158285 (active, not recruiting).Findings From July 13, 2017, to Aug 3, 2018, 1153 patients were screened, of whom 741 were randomly assigned to receive guselkumab every 4 weeks (n=246), every 8 weeks (n=248), or placebo (n=247). One patient in the every 4 weeks group and one in the placebo group did not start treatment, and the remaining 739 patients started treatment; 716 patients continued treatment up to week 24. Significantly greater proportions of patients in the guselkumab every 4 weeks group (156 [64%] of 245 [95% CI 57-70]) and every 8 weeks group (159 [64%] of 248 [58-70]) than in the placebo group ( 81 [33%] of 246 [27-39]) achieved an ACR20 response at week 24 (percentage differences vs placebo 31% [95% CI 22-39] for the every 4 weeks group and 31% [23-40] for the every 8 weeks group; both p<0.0001). Up to week 24, serious adverse events occurred in eight (3%) of 245 patients receiving guselkumab every 4 weeks (three serious infections), three (1%) of 248 receiving guselkumab every 8 weeks (one serious infection), and seven (3%) of 246 receiving placebo (one serious infection). No deaths occurred.Interpretation Guselkumab, a human monoclonal antibody that specifically inhibits IL-23 by binding the cytokine's p19 subunit, was efficacious and demonstrated an acceptable benefit-risk profile in patients with active psoriatic arthritis who were naive to treatment with biologics. These data support the use of selective inhibition of IL-23 to treat psoriatic arthritis. Show less
