RESUMO
OBJECTIVE: To evaluate gene expression in blood of patients with psoriatic arthritis (PsA) versus healthy controls and identify changes associated with guselkumab treatment. METHODS: Whole blood transcriptome profiling via paired-end RNA sequencing was conducted using samples from DISCOVER-1 and DISCOVER-2 at baseline (n = 673) and at weeks 4 and 24 from a representative subgroup that received placebo or guselkumab (n = 227 [longitudinal PsA cohort]). Baseline samples were compared with demographically matched healthy controls (n = 21). Guselkumab-mediated changes in gene expression were assessed in participants from the longitudinal PsA cohort who did versus did not achieve at least 20% improvement in American College of Rheumatology response criteria (ACR20) or at least 75% improvement in Psoriasis Area and Severity Index (PASI75). Differential gene expression was analyzed using edgeR. RESULTS: At baseline, 355 upregulated and 314 downregulated genes (PsA-associated genes) were identified in patients with PsA versus healthy controls. Upregulated genes were related to neutrophil, mononuclear cell, and CD11b+ gene sets. No cell type-specific gene sets were identified among downregulated genes. Most PsA-associated genes were modulated by guselkumab treatment. At week 24, genes downregulated by guselkumab were enriched with neutrophil, monocyte, eosinophil, and macrophage gene sets; genes upregulated by guselkumab were enriched with B cell, T cell, and natural killer cell gene sets. Reductions in expression of upregulated PsA-associated gene sets were more pronounced in ACR20 and PASI75 responders than in nonresponders. CONCLUSION: These findings suggest a dysregulation of immune cell profiles in blood from patients in the baseline PsA cohort that approached levels in healthy controls after guselkumab treatment.
RESUMO
INTRODUCTION: We studied the effect of intravenous (IV)-golimumab on fatigue and the association of fatigue improvement with clinical response post hoc in adults with active ankylosing spondylitis (AS) in the GO-ALIVE trial. METHODS: Patients were randomized to IV-golimumab 2 mg/kg (N = 105) at week (W) 0, W4, then every 8 W (Q8W) or placebo (N = 103) at W0, W4, W12, crossover to IV-golimumab 2 mg/kg at W16, W20, then Q8W through W52. Fatigue measures included Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Question #1 (fatigue; 0 [none], 10 [worst]; decrease indicates improvement) and 36-Item Short Form Health Survey (SF-36) vitality subscale (0 [worst], 100 [best]; increase indicates improvement). Minimum clinically important difference is ≥ 1 for BASDAI-fatigue and ≥ 5 for SF-36 vitality. GO-ALIVE primary endpoint was Assessment of SpondyloArthritis international Society ≥ 20% improvement criteria (ASAS20). Other clinical outcomes assessed included other ASAS responses, Ankylosing Spondylitis Disease Activity Score, and Bath Ankylosing Spondylitis Functional Index score. The distribution-based minimally important differences (MIDs) were determined for BASDAI-fatigue and SF-36 vitality. The relationship between improvement in fatigue and clinical outcomes was assessed via multivariable logistic regression. RESULTS: Mean changes in BASDAI-fatigue/SF-36 vitality scores were greater with IV-golimumab versus placebo at W16 (- 2.74/8.46 versus - 0.73/2.08, both nominal p ≤ 0.003); by W52 (after crossover), differences between groups narrowed (- 3.18/9.39 versus - 3.07/9.17). BASDAI-fatigue/SF-36 vitality MIDs were achieved by greater proportions of IV-golimumab-treated versus placebo-treated patients at W16 (75.2%/71.4% versus 42.7%/35.0%). A one-point/five-point improvement in BASDAI-fatigue/SF-36 vitality scores at W16 increased likelihood of achieving ASAS20 (odds ratios [95% confidence intervals]: 3.15 [2.21, 4.50] and 2.10 [1.62, 2.71], respectively) and ASAS40 (3.04 [2.15, 4.28] and 2.24 [1.68, 3.00], respectively) responses at W16; concurrent improvements and clinical response at W52 were consistent. A one-point/five-point improvement in BASDAI-fatigue/SF-36 vitality scores at W16 predicted increased likelihood of achieving ASAS20 (1.62 [1.35, 1.95] and 1.52 [1.25, 1.86], respectively) and ASAS40 (1.62 [1.37, 1.92] and 1.44 [1.20, 1.73], respectively) responses at W52. CONCLUSIONS: IV-golimumab provided important and sustained fatigue improvement in patients with AS that positively associated with achieving clinical response. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT02186873.
Ankylosing spondylitis (AS) is a type of arthritis that mostly affects the spine. Patients with AS also often have severe fatigue. Intravenous (IV)-golimumab, which blocks the inflammatory action of tumor necrosis factor, is approved to treat AS. We used information from a clinical trial (GO-ALIVE) to determine whether IV-golimumab reduced fatigue in patients with AS, and if fatigue improvement was associated with improvement in other AS symptoms, including spinal pain, ability to function, and inflammation. In the 1-year GO-ALIVE study, patients were assigned to receive either IV-golimumab or placebo. Patients assigned to placebo were switched to IV-golimumab starting at week 16. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) fatigue question and the 36-Item Short Form Health Survey (SF-36) vitality subscale were used to assess fatigue. Improvement in AS symptoms was measured using the Assessment of SpondyloArthritis international Society ≥ 20% and ≥ 40% improvement criteria (ASAS20 and ASAS40). After 16 weeks of treatment, patients treated with IV-golimumab, on average, had statistically significantly greater improvement in both measures of fatigue than patients treated with placebo. At 1 year, after the placebo group had received IV-golimumab starting at week 16, improvement in fatigue was similar between groups. Improvement in fatigue at week 16 increased the likelihood that ASAS20 and ASAS40 would be achieved at week 16. Similar results were observed at 1 year. Additionally, improvement in fatigue at week 16 predicted the likelihood of achieving ASAS20 and ASAS40 at 1 year. Together, these results demonstrate that IV-golimumab provided important, long-term improvement in fatigue in patients with AS that was positively associated with improvement in AS symptoms.
RESUMO
INTRODUCTION: In DISCOVER-2, guselkumab, an interleukin-23 p19 subunit inhibitor, was efficacious in biologic-naïve psoriatic arthritis (PsA) patients. We report the effect of guselkumab on health-related quality of life (HRQoL) using the EuroQol 5-Dimension 5-Level (EQ-5D-5L) Index and Visual Analog Scale (EQ-VAS) through Week 52. METHODS: Adults with active PsA were randomized to guselkumab 100 mg every 4 weeks (Q4W) or Weeks 0, 4, then every 8 weeks (Q8W), or placebo (crossover to guselkumab Q4W at Week 24). Least squares (LS) mean changes in EQ-5D-5L Index (0-1, US-based value set) and EQ-VAS (0-100) from baseline through Week 52 were assessed. Proportions of patients achieving minimally important differences (MIDs) were assessed through Week 52. Associations between patient clinical features and EQ-5D-5L Index and EQ-VAS scores were examined cross-sectionally with pooled data through Week 24. RESULTS: The analysis included 738 patients (Q4W n = 245; Q8W n = 248; placebo n = 245). At Week 24, LS mean changes from baseline in the Q4W, Q8W, and placebo groups were 0.12, 0.12, and 0.05, respectively, for EQ-5D-5L Index, and 18.2, 18.4, and 6.8, respectively, for EQ-VAS. At Week 52, improvement was maintained in the guselkumab groups and increased in the placebo crossover group. EQ-5D-5L Index MID was achieved by 56.0% in each guselkumab group at Week 24 and 66.2% in Q4W, 68.5% in Q8W, and 66.1% in placebo crossover group at Week 52. Higher C-reactive protein level, Psoriasis Area and Severity Index score, fatigue, and pain were correlated with worse EQ-5D-5L Index and EQ-VAS, based on pooled data through Week 24. Higher tender joint count was correlated with worse EQ-5D-5L, while higher swollen joint count was correlated with worse EQ-VAS. CONCLUSIONS: Guselkumab improved HRQoL through 52 weeks in patients with active PsA. Impairment in HRQoL was correlated with increased inflammation, fatigue, pain, and measures of skin and joint symptom severity. CLINICALTRIALS: GOV: NCT03158285.

INTRODUCTION: The phase 3 DISCOVER-2 trial evaluated the effect of guselkumab on impaired work productivity and nonwork activity in biologic-naïve patients with psoriatic arthritis (PsA). METHODS: Adults with active PsA were randomized (1:1:1) to guselkumab 100 mg every 4 weeks (Q4W), guselkumab 100 mg at weeks 0 and 4 and then every 8 weeks (Q8W), or placebo (with crossover to guselkumab Q4W at week 24). Least squares mean change from baseline in Work Productivity and Activity Impairment Questionnaire for PsA (WPAI-PsA) domains and employment were assessed by treatment group. Multivariate analysis of data from weeks 0 through 24 assessed independent associations between PsA clinical features and WPAI-PsA domains. RESULTS: In total, 738 patients were evaluated (guselkumab Q4W n = 245; guselkumab Q8W n = 248; placebo n = 245). At week 24, improvements (reduced impairment) in presenteeism (Q4W -20.1%, Q8W -19.6%, placebo -10.5%), work productivity (Q4W -20.1%, Q8W -19.2%, placebo -10.6%), and nonwork activity (Q4W -20.5%, Q8W -21.2%, placebo -9.9%) were greater in guselkumab-treated versus placebo-treated patients. At week 52, following placebo crossover at week 24, improvements were similar among groups. Baseline absenteeism was minimal and did not change in any group. By week 52, 23.1-25.9% of guselkumab-treated patients who were unemployed at baseline were employed. All WPAI-PsA domains were positively associated with C-reactive protein level, fatigue, and pain. All domains except absenteeism were positively associated with enthesitis and Psoriasis Area and Severity Index score. Age was negatively associated with presenteeism and work productivity loss, female sex and tender joint count were positively associated with nonwork activity impairment, and dactylitis was positively associated with presenteeism. CONCLUSION: Both guselkumab regimens reduced work productivity loss and nonwork activity impairment in patients with active PsA. Association of work productivity loss and nonwork activity impairment with PsA joint and skin features suggests that improvement in both features is beneficial for optimizing improved work productivity loss and nonwork activity impairment.

BACKGROUND/OBJECTIVE: This post hoc analysis assessed efficacy and safety of intravenous (IV) golimumab in ankylosing spondylitis (AS) patients with early disease (ED) versus late disease (LD). METHODS: The phase 3, double-blind, GO-ALIVE study randomized patients to IV golimumab 2 mg/kg at weeks 0 and 4 and then every 8 weeks through week 52, or placebo at weeks 0, 4, and 12 with crossover to IV golimumab at week 16. Clinical efficacy was assessed by ≥20% improvement in Assessment of Spondyloarthritis International Society response criteria (ASAS20), ≥50% improvement in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI 50), and Ankylosing Spondylitis Disease Activity Score (ASDAS) <1.3 (inactive disease). Using self-reported duration of inflammatory back pain (IBP), patients were grouped into quartiles: first = ED and fourth = LD. Descriptive statistics summarized efficacy and safety findings through 1 year. RESULTS: Early disease patients (n = 60) were ~10 years younger and had shorter median AS (IBP) symptom duration (2-3 years) versus LD patients (n = 52; 21-24 years). At week 16, numerically higher proportions of golimumab- than placebo-treated patients achieved ASAS20 (ED: 71% vs. 32%; LD: 67% vs. 21%), BASDAI 50 (ED: 40% vs. 12%; LD: 33% vs. 7%), and ASDAS <1.3 (ED: 17% vs. 4%; LD 8% vs. 0%) regardless of IBP duration. Efficacy was durable through 1 year of treatment; however, response rates were numerically higher in patients with ED versus LD. Through week 60, adverse events and serious adverse events, respectively, were reported by 46% and 3% of ED patients and 61% and 2% of LD patients. CONCLUSION: Prompt diagnosis of AS and early treatment with IV golimumab may yield more robust improvements in disease activity.

OBJECTIVE: The Phase 3 DISCOVER-1 study of guselkumab is the first randomized controlled trial to use Patient-Reported Outcomes Measurement Information System (PROMIS) measures to assess the effects of treatment on general health outcomes in patients with psoriatic arthritis (PsA). METHODS: Patients (N = 381) with active PsA were randomized 1:1:1 to guselkumab 100 mg every 4 weeks (Q4W); guselkumab 100 mg at Week 0, Week 4, then every 8 weeks (Q8W); or placebo with Week 24 crossover to guselkumab Q4W. The PROMIS-29 Profile contains four items for each of seven domains (anxiety, depression, fatigue, pain interference, physical function, sleep disturbance, and social participation) and one pain-intensity item. Raw domain scores are converted to standardized T-scores, with norms based on a US general population mean of 50 (1 standard deviation (SD) = 10). T-score changes of ≥ 5 are considered clinically meaningful. Least-squares mean PROMIS-29 T-score changes from baseline to Week 24 and Week 52 were summarized for the guselkumab and placebo groups; nominal p-values comparing results between guselkumab and placebo were calculated at Week 24 using a mixed model for repeated measures. The proportions of patients who achieved clinically meaningful improvement in PROMIS-29 T-scores were also summarized at Week 24 and Week 52; nominal p-values comparing results between guselkumab and placebo were calculated at Week 24 using the Cochran-Mantel-Haenszel test. RESULTS: In the DISCOVER-1 patient population, mean PROMIS-29 T-scores at baseline were ~ 1 SD worse for physical function and pain interference and were numerically worse for social participation, fatigue, and sleep disturbance compared with the US general population. At Week 24, mean PROMIS-29 T-scores improved in guselkumab-treated patients, approaching US population norms; T-scores continued to improve through Week 52. Significantly higher proportions of patients in both guselkumab treatment arms (31-52% across domains) had clinically meaningful improvements in pain interference, fatigue, physical function, sleep, and social participation at Week 24 versus placebo (all nominal p ≤ 0.05). CONCLUSION: In patients with active PsA, guselkumab treatment provided clinically meaningful reductions in fatigue and pain and improvement in physical function and social participation, as measured by the PROMIS-29 Profile. These improvements were maintained through 1 year. CLINICALTRIALS: GOV: Registration number, NCT03162796; Submission date 19 May 2017.

INTRODUCTION: Guselkumab, a novel interleukin-23p19 subunit monoclonal antibody, has been shown to effectively improve the diverse manifestations of active psoriatic arthritis (PsA) in two phase 3 trials (DISCOVER-1, DISCOVER-2). Serum concentrations of extracellular matrix (ECM) biomarkers at baseline and following treatment with guselkumab were evaluated in patients with active PsA, and the relationship of these biomarkers with baseline PsA characteristics and clinical response to guselkumab treatment was explored. METHODS: Serum samples were collected at weeks 0, 4, 24, and 52 from a selected subset (N = 260) of the 739 biologic-naïve patients with PsA treated with guselkumab 100 mg every 4 or 8 weeks or placebo in DISCOVER-2. Demographically matched healthy controls (N = 76) were used for comparison. The samples were analyzed for ECM biomarkers associated with collagen degradation (C1M, C2M, C3M, C4M, C6M, C10C) and collagen formation (PRO-C1, PRO-C2, PRO-C3, PRO-C4, PRO-C6). RESULTS: Baseline concentrations of collagen degradation biomarkers C1M, C3M, C4M, and C6M and collagen formation biomarkers PRO-C3 and PRO-C6 were significantly higher (i.e., ≥ 1.25-fold and false discovery rate adjusted p < 0.05) in PsA patients than in healthy controls. Serum C1M, C3M, C4M, and C6M levels declined from baseline in guselkumab-treated patients in both dosing regimens. In addition, guselkumab-treated ACR20 responders (≥ 20% improvement in American College of Rhematology response criteria) had significantly lower C1M levels than ACR20 nonresponders. CONCLUSION: These data demonstrate that serum collagen biomarkers are elevated in patients with PsA compared with healthy controls and that treatment with guselkumab decreases levels of C1M, C3M, C4M, and C6M. Importantly, C1M serves as a biomarker that associates with improvement of joint signs and symptoms. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03158285.
RESUMO
BACKGROUND: Intravenous (IV) golimumab, a TNFi, is approved for treating rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS). We analyzed pooled safety results from three phase 3 IV golimumab trials in these rheumatologic diseases and hypothesized that the safety profile of IV golimumab would be similar to that established for other TNFi, including subcutaneous golimumab. METHODS: Data from three double-blind, randomized trials of IV golimumab in patients with RA, PsA, and AS, each with a placebo-controlled period and an extension of active treatment, were included. Golimumab 2 mg/kg was administered at weeks 0 and 4, then every 8 weeks through week 100 (RA) or week 52 (PsA, AS). Concomitant low-dose, oral corticosteroids were permitted. Concomitant methotrexate was required in the RA trial and permitted in the PsA and AS trials; placebo patients crossed over to golimumab at weeks 24 (RA, PsA) and 16 (AS), respectively. Adverse events (AEs), including infections, serious infections, malignancies, and major adverse cardiovascular events (MACE), were assessed through week 112 (RA) or week 60 (PsA, AS). RESULTS: In total, 539 patients were randomized to placebo, and 740 patients were randomized to golimumab; 1248 patients received ≥ 1 golimumab administration. Among the placebo and golimumab patients, respectively, during the placebo-controlled periods, 40.6% and 50.3% had an AE, 2.4% and 3.8% had a serious AE, and 0.4% and 0.8% had a serious infection. Among all golimumab-treated patients, the numbers of events/100 patient-years (95% CI) were as follows: AEs, 175.2 (169.0, 181.6); serious AEs, 12.7 (11.0, 14.5); serious infections, 3.4 (2.5, 4.4); active tuberculosis, 0.4 (0.1, 0.8); opportunistic infection, 0.2 (0.1, 0.6); malignancies, 0.4 (0.2, 0.9), and MACE, 0.5 (0.2, 1.0). There were no cases of lymphoma. Three (0.6%) placebo-treated patients and 6 (0.5%) golimumab-treated patients died during the studies. Concomitant methotrexate was associated with increased occurrence of elevated alanine transaminase levels and lower incidence of antibodies to golimumab. During the placebo-controlled periods, serious infections in the placebo and golimumab groups were more common in patients receiving concomitant low-dose oral corticosteroids vs. those not receiving corticosteroids. CONCLUSIONS: IV golimumab demonstrated a safety profile that was broadly consistent across these rheumatologic indications and with other TNFi, including subcutaneous golimumab. Concomitant methotrexate or corticosteroids were associated with an increase in specific AEs. TRIAL REGISTRATIONS: ClinicalTrials.gov , NCT00973479 . Registered on September 9, 2009.

OBJECTIVE: 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.

BACKGROUND: The interleukin-23p19-subunit inhibitor guselkumab effectively treats signs and symptoms of psoriatic arthritis (PsA). We evaluated the effect of guselkumab on fatigue. METHODS: Across two phase 3 trials of guselkumab (DISCOVER-1, DISCOVER-2), patients with active PsA despite standard therapy were randomized to subcutaneous injections of guselkumab 100 mg every 4 weeks (Q4W, N = 373); guselkumab 100 mg at week 0, week 4, and then Q8W (N = 375); or placebo (N = 372) through week 24, after which patients in the placebo group crossed over to guselkumab Q4W. Fatigue was measured as a secondary endpoint using the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue instrument (range 0-52, higher scores indicate less fatigue). Least-squares mean changes in FACIT-Fatigue scores were compared between treatments using a mixed-effect model for repeated measures. Mediation analysis was used to adjust for indirect effects on fatigue deriving from improvement in other outcomes, including ≥20% improvement in American College of Rheumatology criteria (ACR20; prespecified), minimal disease activity (MDA; post hoc), or C-reactive protein (CRP; post hoc). RESULTS: Baseline mean (SD) FACIT-Fatigue scores in DISCOVER-1 (N = 381) and DISCOVER-2 (N = 739), ranging from 29.1 (9.5) to 31.4 (10.1), indicated substantial levels of fatigue relative to the United States general population (43.6 [9.4]). Across studies, mean improvements, and proportions of patients with ≥4-point improvements, in FACIT-Fatigue scores at week 24 with guselkumab Q4W and Q8W (5.6-7.6 and 54-63%, respectively) were larger vs placebo (2.2-3.6 and 35-46%). Improvement in FACIT-Fatigue scores with guselkumab was sustained from week 24 to week 52, with moderate-to-large effect sizes (Cohen's d = 0.52-0.81 at week 24; 0.66-0.91 at week 52). Mediation analyses demonstrated that substantial proportions of the effects of guselkumab vs placebo on fatigue were direct effect, after adjusting for achievement of ACR20 (Q4W 69-70%, Q8W 12-36% direct effect) or MDA (72-92% across dosing regimens) response or for change in serum CRP concentrations (82-88% across dosing regimens). CONCLUSIONS: In patients with active PsA, guselkumab 100 mg Q4W or Q8W led to clinically meaningful and sustained improvements in fatigue through 1 year. A substantial portion of the improvement in FACIT-Fatigue scores induced by guselkumab was independent of effects on the achievement of other select outcomes.

OBJECTIVE: Evaluate the safety of guselkumab (monoclonal antibody targeting interleukin [IL]-23p19) in patients with psoriatic arthritis (PsA) through 1 year (1Y) of the phase III DISCOVER-1 and DISCOVER-2 trials. METHODS: Patients with active PsA (n = 1120; biologic-naïve except 118 patients treated with tumor necrosis factor inhibitors in DISCOVER-1) were randomized to subcutaneous guselkumab 100 mg every 4 weeks (Q4W) or at Week 0, Week 4, then every 8 weeks (Q8W); or placebo. At Week 24, patients in the placebo group switched to guselkumab 100 mg Q4W. Treatment continued through 1Y and 2 years for DISCOVER-1 and DISCOVER-2, respectively. In this pooled analysis, patients with ≥ 1 adverse event (AE) through 1Y were standardized for 100 patient-years [100 PYs] of follow-up. RESULTS: Through Week 24, adverse events (AEs) were consistent between patients treated with placebo and guselkumab (Q4W + Q8W). AEs were 142.8/100 PYs and 150.6/100 PYs, serious AEs were 7.1/100 PYs and 4.4/100 PYs, and AEs leading to study agent discontinuation were 4.1/100 PYs and 3.8/100 PYs, respectively. Through 1Y in patients treated with guselkumab, no uveitis, active tuberculosis, opportunistic infections, or inflammatory bowel disease were observed, and low rates of malignancy and major adverse cardiovascular (CV) events were observed. Injection-site reactions occurred in 1.7%, and antibodies to guselkumab in 4.5% of patients treated with guselkumab through 1Y; the vast majority of antibodies to guselkumab were nonneutralizing. Serum hepatic transaminase elevations (more common with Q4W than Q8W dosing) and decreased neutrophil counts were generally mild, transient, and did not require treatment discontinuation, with minimal change from Week 24 to 1Y. CONCLUSION: Guselkumab 100 mg Q4W and Q8W were well tolerated in patients with PsA, with no new safety concerns through 1Y of the phase III DISCOVER trials. Guselkumab safety through 1Y in patients with PsA is consistent with that established in patients with psoriasis who were treated with guselkumab. [ClinicalTrials.gov: NCT03162796 and NCT03158285].

OBJECTIVE: To further characterize the effect of guselkumab, a selective IL-23p19-subunit inhibitor approved for PsA, on enthesitis and assess relationships between enthesitis resolution and patient status/outcomes. METHODS: Adults with active PsA despite standard therapies in the phase 3 DISCOVER-1 and DISCOVER-2 studies were randomized 1:1:1 to guselkumab 100 mg every 4 weeks (Q4W); guselkumab 100 mg at week 0, week 4, Q8W; or placebo through week 20 followed by guselkumab 100 mg Q4W. Independent assessors evaluated enthesitis using the Leeds Enthesitis Index (LEI; total score 0-6). Enthesitis findings through week 24 were pre-specified to be pooled across studies; post hoc and week 52 analyses also employed pooled data. RESULTS: Among 1118 randomized, treated patients in DISCOVER-1 and 2 who had ≥1 LEI site evaluated, 65% had enthesitis at baseline. These patients exhibited numerically more swollen and tender joints, systemic inflammation and impaired physical function than patients without enthesitis. Guselkumab Q4W and Q8W were superior to placebo in resolving pre-existing enthesitis at week 24 (45 and 50% vs 29%; both adjusted P = 0.0301). Enthesitis resolution rates continued to rise; 58% of guselkumab-randomized patients achieved resolution at week 52, including patients with mild (LEI = 1; 70-75%), moderate (LEI = 2; 69-73%) or severe (LEI = 3-6; 42-44%) enthesitis at baseline. Among guselkumab-randomized patients with resolved enthesitis at week 24, 42% achieved minimal disease activity at week 52, vs 17% of patients with unresolved enthesitis. CONCLUSION: Guselkumab resulted in higher proportions of PsA patients with resolved enthesitis by week 24, with maintenance of resolution rates through 1 year. As enthesitis confers greater disease burden, sustained resolution could portend better patient outcomes. CLINICAL TRIAL REGISTRATION: DISCOVER 1 (NCT03162796) and DISCOVER 2 (NCT03158285).

INTRODUCTION/OBJECTIVES: To evaluate changes in health-related quality of life (HRQoL) and productivity following treatment with intravenous (IV) golimumab in patients with psoriatic arthritis (PsA). METHODS: Patients were randomized to IV golimumab 2 mg/kg (n=241) at Weeks 0, 4, then every 8 weeks (q8w) through Week 52 or placebo (n=239) at Weeks 0, 4, then q8w, with crossover to IV golimumab 2 mg/kg at Weeks 24, 28, then q8w through Week 52. Change from baseline in EuroQol-5 dimension-5 level (EQ-5D-5L) index and visual analog scale (EQ-VAS), daily productivity VAS, and the Work Limitations Questionnaire (WLQ) was assessed. Relationships between these outcomes and disease activity and patient functional capability were evaluated post hoc. RESULTS: At Week 8, change from baseline in EQ-5D-5L index (0.14 vs 0.04), EQ-VAS (17.16 vs 3.69), daily productivity VAS (-2.91 vs -0.71), and WLQ productivity loss score (-2.92 vs -0.78) was greater in the golimumab group versus the placebo group, respectively. At Week 52, change from baseline was similar in the golimumab and placebo-crossover groups (EQ-5D-5L index: 0.17 and 0.15; EQ-VAS: 21.61 and 20.84; daily productivity VAS: -2.89 and -3.31; WLQ productivity loss: -4.49 and -3.28, respectively). HRQoL and productivity were generally associated with disease activity and functional capability, with continued association from Week 8 through Week 52. CONCLUSION: IV golimumab resulted in early and sustained improvements in HRQoL and productivity from Week 8 through 1 year in patients with PsA. HRQoL and productivity improvements were associated with improvements in disease activity and patient functional capability. Key Points ⢠In patients with active psoriatic arthritis (PsA), intravenous (IV) golimumab improved health-related quality of life (HRQoL) and productivity as early as 8 weeks and maintained improvement through 1 year ⢠Improvements in HRQoL and productivity outcomes in patients with PsA treated with IV golimumab were associated with improvements in disease activity and patient functional capability outcomes ⢠IV golimumab is an effective treatment option for PsA that can mitigate the negative effects of the disease on HRQoL and productivity.

OBJECTIVE: Evaluation of the efficacy and safety of guselkumab, a human monoclonal antibody targeting the interleukin-23p19 subunit, in patients with psoriatic arthritis (PsA) through 1 year. METHODS: Adults who met ClASsification criteria for Psoriatic ARthritis, with active disease (≥3 swollen and ≥3 tender joints; C reactive protein ≥0.3 mg/dL) despite standard treatment (31% previously received ≤2 tumour necrosis factor inhibitors (TNFi)), were randomised (1:1:1) to guselkumab 100 mg every 4 weeks (Q4W); guselkumab 100 mg at Week0, Week4, then Q8W; or placebo with cross-over to guselkumab 100 mg Q4W at Week24 (PBOâQ4W) through Week48. Clinical efficacy through Week52 (employing non-responder imputation) and adverse events (AEs) through Week60 were evaluated. RESULTS: Of 381 treated patients, 90% completed the study. Numerical increases in the proportions of patients achieving ≥20% improvement in ACR criteria (ACR20) were observed post-Week24, reaching 73% (94/128) and 60% (76/127) for Q4W-randomised and Q8W-randomised patients, respectively, by Week52. Proportions of patients achieving ACR50/ACR70/skin responses and minimal/very low disease activity were maintained, as were improvements in physical function and health-related quality of life, through Week52 in guselkumab-randomised patients. Response to guselkumab was maintained in both TNFi-naïve and TNFi-experienced patients. Serious AEs and serious infections occurred in similar proportions of guselkumab Q4W-randomised (3% and 0%) and Q8W-randomised (6% and 2%) patients through Week60, with no new safety concerns versus observations through Week24. No guselkumab-treated patient and two patients receiving placebo died; no study participant developed opportunistic infection or inflammatory bowel disease. CONCLUSION: Guselkumab provided sustained improvement across multiple clinical manifestations of PsA, maintaining a favourable benefit-risk profile, through 1 year regardless of prior TNFi exposure.

OBJECTIVES: To assess efficacy, pharmacokinetics (PK) and safety of intravenous (i.v.) golimumab in patients with polyarticular-course JIA (pc-JIA). METHODS: Children aged 2 to <18 years with active pc-JIA despite MTX therapy for ≥2 months received 80 mg/m2 golimumab at weeks 0, 4, then every 8 weeks through week 52 plus MTX weekly through week 28. The primary and major secondary endpoints were PK exposure and model-predicted steady-state area under the curve (AUCss) over an 8-week dosing interval at weeks 28 and 52, respectively. JIA ACR response and safety were also assessed. RESULTS: In total, 127 children were treated with i.v. golimumab. JIA ACR 30, 50, 70, and 90 response rates were 84%, 80%, 70% and 47%, respectively, at week 28 and were maintained through week 52. Golimumab serum concentrations and AUCss were 0.40 µg/ml and 399 µg â day/ml at week 28. PK exposure was maintained at week 52. Steady-state trough golimumab concentrations and AUCss were consistent across age categories and comparable to i.v. golimumab dosed 2 mg/kg in adults with rheumatoid arthritis. Golimumab antibodies and neutralizing antibodies were detected via a highly sensitive drug-tolerant assay in 31% (39/125) and 19% (24/125) of patients, respectively. Median trough golimumab concentration was lower in antibody-positive vs antibody-negative patients. Serious infections were reported in 6% of patients, including one death due to septic shock. CONCLUSION: Body surface area-based dosing of i.v. golimumab was well tolerated and provided adequate PK exposure for clinical efficacy in paediatric patients with active pc-JIA.ClinicalTrials.gov number NCT02277444.

OBJECTIVE: 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.

INTRODUCTION/OBJECTIVES: The effect of intravenous (IV) golimumab on health-related quality of life (HRQoL) and productivity in patients with ankylosing spondylitis (AS) was evaluated. METHOD: Patients were randomized to IV golimumab 2 mg/kg (n = 105) at weeks 0, 4, then every 8 weeks (q8w) through week 52 or placebo (n = 103) at weeks 0, 4, 12, with crossover to golimumab 2 mg/kg at weeks 16, 20, then q8w through week 52. Changes from baseline in EuroQol-5 dimension-5 level (EQ-5D-5L) index and visual analog scale (EQ-VAS), daily productivity VAS, Work Limitations Questionnaire (WLQ), and Ankylosing Spondylitis Quality of Life (ASQoL) were assessed. Correlations between these outcomes and disease activity and patient functioning outcomes were evaluated post hoc. RESULTS: At week 16, changes from baseline (mean ± standard deviation) in EQ-5D-5L index (0.17 ± 0.16 vs 0.05 ± 0.14), EQ-VAS (20.3 ± 24.6 vs 4.8 ± 23.5), daily productivity VAS (- 2.9 ± - 2.9 vs - 1.1 ± - 2.5), WLQ productivity loss score (- 3.5 ± - 5.3 vs - 1.9 ± - 4.0), and ASQoL (- 5.4 ± - 5.0 vs - 1.8 ± - 4.5) were greater in the IV golimumab versus placebo group, respectively. At week 28, changes from baseline were similar between the IV golimumab and placebo-crossover groups (EQ-5D-5L index: 0.18 ± 0.17 and 0.16 ± 0.16, EQ-VAS: 20.5 ± 27.9 and 22.5 ± 23.1, daily productivity VAS: - 3.1 ± - 3.0 and - 3.1 ± - 2.8, WLQ productivity loss: - 3.9 ± - 5.5 and - 4.5 ± - 4.5, and ASQoL: - 5.3 ± - 5.2 and - 5.3 ± - 4.8, respectively); improvements were maintained through week 52. HRQoL and productivity outcomes were generally moderately correlated with disease activity and functioning outcomes. CONCLUSIONS: In patients with AS, IV golimumab produced sustained improvements in HRQoL and productivity through 1 year, which correlated with improvements in disease activity and functioning. ClinicalTrials.gov registry number is NCT02186873. Key Points ⢠Intravenous (IV) golimumab resulted in clinically important improvement in general and ankylosing spondylitis-specific health-related quality of life (HRQoL) and productivity outcomes in patients with ankylosing spondylitis (AS) as early as week 8 and maintained improvement through 1 year ⢠Improvements in HRQoL and productivity outcomes in these patients with AS were correlated with improvements in measures of disease activity and patient functional capability ⢠IV golimumab is an effective treatment option for AS that can help mitigate the negative effects of the disease on HRQoL and productivity.

BACKGROUND: Guselkumab was efficacious in reducing signs and symptoms of psoriatic arthritis in the phase 3 DISCOVER-1 and DISCOVER-2 studies. We aimed to evaluate the efficacy of guselkumab in post-hoc analyses of patients with psoriatic arthritis with imaging-confirmed sacroiliitis consistent with axial involvement. METHODS: In DISCOVER-1, 381 patients with active psoriatic arthritis (defined as ≥3 swollen joints, ≥3 tender joints, and C-reactive protein [CRP] ≥0·3 mg/dL) and in DISCOVER-2, 739 patients with active psoriatic arthritis (defined as ≥5 swollen joints, ≥5 tender joints, and CRP ≥0·6 mg/dL) were randomly allocated to receive guselkumab 100 mg every 4 weeks, guselkumab 100 mg every 8 weeks (week 0, week 4, then every 8 weeks), or placebo. These pooled, post-hoc analyses included patients with axial disease documented by previous imaging or pelvic radiography at screening consistent with sacroiliitis (confirmed by investigator). Efficacy assessments included least squares mean changes, with 95% CIs, in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score, modified BASDAI (mBASDAI; excluding peripheral joint pain), spinal pain, and Ankylosing Spondylitis Disease Activity Score (ASDAS), and proportions of patients achieving at least a 50% improvement in BASDAI score (BASDAI50) and achieving ASDAS responses of inactive disease (score <1·3), major improvement (change of ≥2·0), and clinically important improvement (change of ≥1·1). FINDINGS: Of the 1120 patients in the two DISCOVER studies, 312 (28%) were included in this analysis, of whom 118 were in the placebo group, 103 were in the guselkumab every 4 weeks group, and 91 were in the guselkumab every 8 weeks group. 191 (61%) were male, and 121 (39%) were female, and the mean age was 45·1 (SD 11·2). HLA-B27 status was assessed in 190 patients; 57 (30%) were HLA-B27-positive and 133 (70%) were HLA-B27-negative. At week 24, least squares mean changes from baseline in BASDAI were -2·7 (95% CI -3·2 to -2·2) in both guselkumab groups versus -1·3 (-1·8 to -0·9) in the placebo group; similar results were observed for mBASDAI and spinal pain. Least squares mean changes in ASDAS scores at week 24 were -1·4 (95% CI -1·7 to -1·2) in both guselkumab groups and -0·7 (-0·9 to -0·5) for placebo. At week 24, 36 (38%) patients in the guselkumab every 4 weeks group and 34 (40%) of those in the guselkumab every 8 weeks group achieved BASDAI50 versus 21 (19%) of placebo patients; greater proportions of guselkumab-treated patients achieved ASDAS responses versus placebo. Across outcomes, separation from placebo was observed at week 8. Improvements with guselkumab were seen at week 24 independent of HLA-B27 status. These improvements were maintained at week 52 in the guselkumab groups. INTERPRETATION: Patients with active psoriatic arthritis and imaging-confirmed sacroiliitis who were treated with guselkumab every 4 weeks or every 8 weeks had greater mean improvements in BASDAI and ASDAS (as early as week 8) than did placebo-treated participants, with sustained improvements at week 52.
