ObjectiveAssess pooled safety results through the end of the phase II/III studies of guselkumab (GUS; ≤ 2 years) in tumor necrosis factor inhibitor (TNFi)-naïve and -experienced patients with psoriatic arthritis (PsA).MethodsData were pooled from the Phase 2 and DISCOVER-1 (both TNFi-naïve and -experienced), DISCOVER-2 (TNFi-naïve), and COSMOS (TNFi-experienced) studies. Patients with active PsA were randomized to GUS 100 mg every 4 or 8 weeks (Q4W + Q8W = Combined GUS) or placebo (PBO) with crossover to GUS Q4W or Q8W at week 24. Time-adjusted adverse event (AE) rates (events/100 patient-years [PY]) and clinical laboratory findings were assessed during the PBO-controlled period and through end of study (≤ 2 years).ResultsOf 1554 randomized patients (n = 373 [GUS Q4W], 664 [GUS Q8W], and 517 [PBO]), 1138 (73.23%) were TNFi-naïve and 416 (26.77%) were TNFi-experienced. Respective AE rates through week 24 were 220.8/100 PY (TNFi-naïve) and 251.6/100 PY (TNFi-experienced) in the Combined GUS group and 196.1/100 PY (TNFi-naïve) and 303.0/100 PY (TNFi-experienced) in the PBO group. Among all GUS-treated patients (including those who crossed over from PBO), low AE rates were maintained during long-term evaluation in both TNFi-naïve (139.7/100 PY) and TNFi-experienced (174.0/100 PY) patients. Rates/100 PY of AEs leading to treatment discontinuation, serious AEs, and other AEs of interest, as well as occurrence of elevated hepatic transaminase levels and decreased neutrophil counts were consistent between PBO and GUS-treated patients through week 24 regardless of prior TNFi use and remained low through the end of the studies.ConclusionThe safety profile of GUS in TNFi-experienced patients was consistent with that in TNFi-naïve patients, which remained favorable for up to 2 years.

Background 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-naïve 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 antirheumatic 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-Haenszel 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. Trial registration This trial was registered at ClinicalTrials.gov, NCT04882098. Registered on 11 May 2021.

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.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).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.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.ClinicalTrials.gov identifier: 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.TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT03158285.

Objectives To evaluate the efficacy of guselkumab for the treatment of active PsA utilizing composite indices. Methods Data were pooled from the phase 3 DISCOVER-1 (n = 381) and DISCOVER-2 (n = 739) studies. In both studies, patients were randomized 1:1:1 to subcutaneous guselkumab 100 mg every 4 weeks (Q4W); guselkumab 100 mg at week 0, week 4, then Q8W; or placebo Q4W with crossover to guselkumab 100 mg Q4W at week 24. Composite indices used to assess efficacy through week 52 included Disease Activity Index for Psoriatic Arthritis (DAPSA), Psoriatic Arthritis Disease Activity Score (PASDAS), minimal disease activity (MDA), and very low disease activity (VLDA). Through week 24, treatment failure rules were applied. Through week 52, non-responder imputation was used for missing data. Results Greater proportions of guselkumab- than placebo-treated patients achieved DAPSA low disease activity (LDA) and remission, PASDAS LDA and VLDA, MDA, and VLDA at week 24 vs placebo (all unadjusted P Conclusion Treatment with guselkumab provided robust and sustained benefits across multiple PsA domains through 1 year, indicating that guselkumab is an effective therapy for the diverse manifestations of PsA.

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).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).

ObjectivesTo evaluate the efficacy through 52 weeks of guselkumab, an interleukin 23-p19 subunit inhibitor, in subgroups of pooled psoriatic arthritis (PsA) patients from the DISCOVER-1 and DISCOVER-2 trials defined by baseline patient characteristics.MethodsAdults with active PsA despite standard therapies were enrolled in DISCOVER-1 (≥3 swollen and ≥3 tender joints, C reactive protein (CRP) level ≥0.3 mg/dL) and DISCOVER-2 (≥5 swollen and ≥5 tender joints, CRP ≥0.6 mg/dL, biological-naïve). Randomised patients received 100 mg guselkumab at weeks 0, 4, and then every 4 or 8 weeks (Q4W/Q8W) or placebo. Guselkumab effects on joint (ACR20/50/70), skin (IGA 0/1, IGA 0), patient-reported outcome (Health Assessment Questionnaire Disability Index/Functional Assessment of Chronic Illness Therapy-Fatigue) and disease severity (minimal disease activity/PsA Disease Activity Score low disease activity) endpoints were evaluated by patient sex, body mass index, PsA duration, swollen/tender joint counts, CRP level, percent body surface area with psoriasis, Psoriasis Area and Severity Index score, and conventional synthetic disease-modifying antirheumatic drug use at baseline.ResultsBaseline patients characteristics in DISCOVER-1 (N=381) and DISCOVER-2 (N=739) were well balanced across randomised groups. At week 24, 62% (232/373) and 60% (225/375), respectively, of guselkumab Q4W-treated and Q8W-treated patients pooled across DISCOVER-1 and DISCOVER-2 achieved the primary endpoint of ACR20 response versus 29% (109/372) of placebo-treated patients. Guselkumab treatment effect at week 24 was observed across patient subgroups. Within each patient subgroup, response rates across all disease domains were sustained or increased at week 52 with both guselkumab regimens.ConclusionsGuselkumab Q4W and Q8W resulted in robust and sustained improvements in PsA signs and symptoms consistently in subgroups of patients defined by diverse baseline characteristics.Trial registration numbersNCT03162796, NCT03158285.

ObjectiveEvaluate relationship between radiographic progression and clinical outcomes in post hoc analyses of patients with psoriatic arthritis (PsA) receiving up to 2 years of guselkumab therapy in the phase 3, placebo-controlled, randomised trial, DISCOVER-2.MethodsBiologic-naïve adults with active PsA (≥5 swollen joints /≥5 tender joints ; C reactive protein ≥0.6 mg/dL) were randomised to guselkumab 100 mg every 4 weeks (Q4W); guselkumab 100 mg at week 0, week 4, then every 8 weeks (Q8W); or placebo→guselkumab 100 mg Q4W (week 24). Radiographs (hands/feet) at week 0, week 24, week 52 and week 100 were scored via PsA-modified van der Heijde-Sharp (vdH-S) methodology. In these post hoc analyses, mean changes in vdH-S scores were summarised according to achievement of American College of Rheumatology 20/50/70 response; low disease activity (LDA) defined by Disease Activity in Psoriatic Arthritis (DAPSA) ≤14 or Psoriatic ArthritiS Disease Activity Score (PASDAS) ≤3.2, or minimal/very low disease activity (MDA/VLDA); and normalised physical function (Health Assessment Questionnaire-Disability Index (HAQ-DI) ≤0.5). Response rates for achieving MDA/VLDA and each component were determined among patients with and without radiographic progression (change in total vdH-S score >0.5). No formal hypothesis testing was performed.Results664 of 739 treated patients in DISCOVER-2 continued study treatment at week 52 and were included in these analyses. Mean changes in vdH-S scores from weeks 0 to 100 among all patients in the Q4W and Q8W groups were 1.7 and 1.5, respectively. Among all guselkumab-randomised patients, those who achieved ACR20/50/70, DAPSA LDA, PASDAS LDA, MDA, VLDA and HAQ-DI ≤0.5 (normalised physical function) had smaller mean changes in vdH-S scores than did non-responders at week 52 (0.2–1.2 vs 1.7–4.1) and week 100 (0.3–1.2 vs 2.0–4.6). Relative to patients with radiographic progression, those without progression were more likely to achieve the MDA criteria related to swollen and tender joint counts, patient-reported pain and global assessment, and normalised physical function through week 100.ConclusionIn these post hoc analyses, the achievement of low levels of disease activity, including MDA, was associated with diminished rates of radiographic progression observed in patients receiving up to 2 years of guselkumab. Radiographic non-progressors were more likely to achieve patient-reported MDA criteria of minimal pain and normalised physical function compared with radiographic non-responders.Trial registration numberNCT03158285.

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.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.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).In biologic-naive PsA patients, guselkumab provided durable improvements in multiple disease domains with no unexpected safety findings through 2 years.

Background Guselkumab (GUS), an anti-interleukin-23p19 monoclonal antibody, is approved to treat psoriasis (PsO). We evaluated GUS efficacy and safety in a Phase 3, double-blind, placebo (PBO)-controlled trial in patients with active PsA who were biologic-naïve or prior TNFα inhibitor (TNFi)-treated (DISCOVER-1). Methods Adults with active PsA (≥3 swollen + ≥3 tender joints; CRP ≥0.3mg/dL) despite standard therapies (eg, non-biologic DMARDs, apremilast, or NSAIDs) were eligible. ∼30% of patients previously could have received or have had inadequate response to 1-2 TNFi. Patients were randomised 1:1:1, stratified by Week [W]0 DMARD use and prior TNFi use, to GUS 100mg Q4W; GUS 100mg at W0, W4, Q8W (Q8W); or PBO. Concomitant stable use of select non-biologic DMARDs, oral corticosteroids, and NSAIDs was allowed. At W16, patients with Results 381 patients were treated and analyzed; baseline characteristics were consistent with moderate-to-severe disease (mean BSA involved with PsO: 13.4%, patients with IGA=3-4: 42.5%; mean swollen/tender joint counts: 9.8/19.3). Significantly more patients receiving GUS Q4W (58.6%) and Q8W (52.8%) vs PBO (22.2%, both p < 0.001) achieved ACR20 response at W24. Consistent response rates were observed in the subgroups of patients with or without prior TNFi use. Significantly greater improvements in HAQ-DI and SF-36 PCS scores were seen in GUS- vs PBO-treated patients from W0 to W24. Among 249 patients with ≥3% BSA PsO and IGA ≥2 at W0, significantly more GUS- vs PBO-treated patients achieved IGA response. Higher proportions of patients achieved ACR20 response at W16, ACR50 response at W16/24, ACR70 response at W24, and PASI75/90/100 responses at W24. More GUS Q4W- or Q8W- vs PBO-treated patients achieved MDA response at W24. Serious AEs, serious infections, and death occurred in 9/381 (2.4%), 2/381 (0.5%), and 1/381 (0.3%) patients, respectively. Conclusion In patients with active PsA who were biologic-naïve or had been treated with TNFi, both GUS Q4W and Q8W demonstrated efficacy for joint and skin symptoms, physical function, and quality of life relative to PBO. Observed AEs were consistent with GUS safety established in PsO. Disclosures A. Deodhar: Other; A.D. has been a study investigator for Janssen clinical trials. P.

Data from preclinical and clinical studies support the evaluation of histamine 4 receptor antagonists in the treatment of asthma. Toreforant is a selective histamine 4 receptor antagonist that could be effective in patients with eosinophilic asthma.To evaluate the efficacy and safety of toreforant in patients with eosinophilic, persistent asthma that was inadequately controlled despite current treatment.In this phase 2a, multicenter, randomized, double-blinded, parallel-group, placebo-controlled, proof-of-concept study, 162 eligible patients were randomized (1:1) to placebo or 30 mg of toreforant once daily through week 24 and followed for 4 weeks. The primary end point was change from baseline in pre-bronchodilator percent-predicted forced expiratory volume in 1 second at week 16. Secondary end points included change from baseline at week 16 in postbronchodilator percent-predicted forced expiratory volume in 1 second, Asthma Control Questionnaire scores, weekly averages of Daytime and Nighttime Asthma Diary Symptom Scores, and weekly average of number of puffs in a day that rescue medication was used.There was no significant difference between groups in pre-bronchodilator percent-predicted forced expiratory volume in 1 second at week 16 (difference in least-square means -0.19%; 95% confidence interval -3.01 to 2.64; P = .90). Similarly, there were no significant differences between groups at week 16 in changes from baseline in the secondary end points (P ≥ .30). Toreforant was generally well tolerated. No deaths or serious adverse events were reported at any time point.Toreforant, at the dose tested, failed to provide therapeutic benefit in this population of patients with uncontrolled, eosinophilic, persistent asthma.ClinicalTrials.gov, NCT01823016.

The objective was to compare the effects on glycemia of adding either inhaled human insulin (Exubera [EXU] [insulin human (recombinant DNA origin) inhalational powder]) or subcutaneous insulin glargine (GLA) to the treatment regimens of patients with type 2 diabetes uncontrolled with oral antidiabetic drugs.Forty patients were randomized to receive either EXU three times daily prior to meals or subcutaneous GLA once daily in a crossover design. Interstitial glucose concentrations were monitored using a continuous glucose monitoring system (CGMS) for the final 72-h period of 8 treatment days.Total insulin dosage on the last treatment day was approximately 40.1+/-18.1 units/day EXU compared with 16.4+/-4.8 units/day GLA. Serum insulin levels over the 72-h CGMS period were higher for EXU than for GLA (1,091+/-589 pmol/mL/h vs. 737+/-386 pmol/mL/h; ratio, 148; 95% confidence interval [CI], 130-169). The glucose exposure over this period was lower with EXU than with GLA (380+/-45 mmol/Lh vs. 426+/-89 mmol/Lh; ratio, 88.57; 95% CI, 84-93). The overall hypoglycemic event rate was 8.7 events per subject-month for EXU and 2.4 for GLA.Prandial insulin therapy with EXU, using a higher daily insulin dose, reduces total daily glucose exposure--in particular postmeal glycemia--more effectively than a basal insulin analog.

The primary aim was to evaluate duration of action of a single 0.8 U/kg dose of insulin lispro protamine suspension (ILPS) in type 2 diabetes (T2DM) patients; secondarily to compare onset and duration of action of ILPS, glargine (G), and detemir (D) (0.8 U/kg) and evaluate pharmacokinetic (PK) and pharmacodynamic (PD) dose responses of ILPS.In a single-center, double-blind, five-arm crossover study, 34 patients were randomized to a treatment sequence which included a single subcutaneous 0.8 U/kg dose of G and D and three doses of ILPS (0.4 U/kg, 0.8 U/kg, and 1.2 U/kg) and were studied using 24-hour euglycemic glucose clamps.Duration of action was determined as the time to the last measurable glucose infusion rate (tR(last)) during glucose clamps.The duration of insulin action (tR(last)) for ILPS at 0.8 U/kg was23 hours and was similar to G (p = 0.114) and D (p = 0.570). Post-hoc analysis demonstrated the probability of achieving 24 hours of glucose-lowering activity after a 0.8 U/kg dose: 48% (ILPS), 43% (G), and 26% (D). G(tot) and R(max) were significantly greater for ILPS versus G or D. The median ILPS time-dependent values demonstrated a significantly earlier maximum PD response (tR(max) and early 50% tR(max)) versus either G or D. ILPS demonstrated dose-dependent increases in PK and PD measures across the dose range.Following a single 0.8 U/kg dose in T2DM patients, ILPS, G, and D demonstrated similar durations of glucose-lowering activity and ILPS demonstrated significantly greater glucose-lowering activity (R(max) and G(tot)) and earlier maximum PD response. These results potentially support once-daily dosing of ILPS in T2DM.The observed number of 24-hour censored observations was higher than expected and the wash-out period for basal insulin treated patients may have been too short to definitively rule out a carry-over effect; however, such an effect, if present, would potentially only affect onset of action and not the primary outcome measure.
