A Study to Investigate the Efficacy and Safety of an Anti-Interleukin-18 Monoclonal Antibody in the Treatment of Type 2 Diabetes Mellitus.

ABSTRACT: OBJECTIVE:Evidence suggests that chronic subclinical inflammation plays an important role in the pathogenesis of type 2 diabetes (T2DM). Circulating levels of interleukin (IL)-18 appear to be associated with a number of micro- and macrovascular comorbidities of obesity and T2DM. This study was designed to investigate whether inhibition of IL-18 had any therapeutic benefit in the treatment of T2DM. Preliminary efficacy, safety and tolerability, pharmacokinetics, and pharmacodynamics of the anti-IL-18 monoclonal antibody, GSK1070806, were assessed. RESEARCH DESIGN AND METHODS:This was a multicentre, randomized, single-blind (sponsor-unblinded), placebo-controlled, parallel-group, phase IIa trial. Obese patients of either sex, aged 18-70 years, with poorly controlled T2DM on metformin monotherapy were recruited. Patients received two doses, of placebo (n = 12), GSK1070806 0.25 mg/kg (n = 13) or GSK1070806 5 mg/kg (n = 12). The primary end-point was the change from baseline in fasting plasma glucose and weighted mean glucose area under the curve (AUC)(0-4 hours) postmixed meal test on Days 29, 57, and 85. RESULTS:Thirty-seven patients were randomized to one of the three treatment arms. There were no statistically significant effects of GSK1070806 doses on fasting plasma glucose levels, or weighted mean glucose AUC(0-4 hours) compared with placebo. CONCLUSIONS:GSK1070806 was well tolerated, and inhibition of IL-18 did not lead to any improvements in glucose control. However, because of study limitations, smaller, potentially clinically meaningful effects of IL-18 inhibition cannot be excluded. TRIAL REGISTRATION:ClinicalTrials.gov NCT01648153.

Project description:ImportancePalmoplantar pustulosis (PPP) is a recalcitrant skin disease with no biologics currently approved for treatment. The involvement of interleukin 23 (IL-23) and cytokines of the type 17 helper T cell lineage in the pathogenesis of PPP has been recently postulated.ObjectiveTo evaluate the efficacy and safety of guselkumab, an anti-IL-23 monoclonal antibody, in Japanese patients with PPP.Design, setting, and participantsThis double-blind, randomized, placebo-controlled, parallel-group, 24-week trial was conducted between May 14, 2013, and September 27, 2014, at 11 centers in Japan. Participants were patients with moderate to severe PPP that did not respond adequately to conventional treatments.InterventionsPatients were randomized 1:1 to receive guselkumab, 200 mg, by subcutaneous injection or matching placebo at weeks 0 and 4.Main outcomes and measuresChanges in total scores of skin-related outcomes from baseline at the end of week 16 (primary clinical cutoff) and through week 24 were measured. Serum biomarker analyses were performed at baseline, week 4, and week 16, and safety was monitored through week 24.ResultsOf 49 randomized patients (35 [71%] women; median [range] age, 52 [28-77] years), 41 completed the study at week 24. Mean (SD) PPP severity index total scores (primary end point) improved significantly from baseline in guselkumab-treated patients (-3.3 [2.43]) vs placebo (-1.8 [2.09]) (least squares mean difference, -1.5; 95% CI, -2.9 to -0.2; P = .03). At week 16, PPP area and severity index scores (least squares mean difference, -5.65; 95% CI, -9.80 to -1.50; P = .009) and proportion of patients achieving 50% reduction in these scores (difference in proportion, 39.2; 95% CI, 14.0-64.3; P = .009) improved significantly. A numerically higher proportion of patients had a physician's global assessment score of 1 or less in the guselkumab group vs placebo. Improvement in efficacy scores was maintained through week 24 in the guselkumab group. Significant reductions from baseline in serum IL-17A and IL-17F cytokine levels were observed at weeks 4 and 16. Frequency of treatment-emergent adverse events was comparable between the guselkumab group (19 of 25 patients [76%]) and the placebo group (18 of 24 patients [75%]). Frequent adverse effects included nasopharyngitis (14 patients [29%]), headache (3 patients [6%]), contact dermatitis (3 patients [6%]), and injection site erythema (3 patients [6%]). No major safety concerns emerged during the study.Conclusions and relevanceTargeting IL-23 and its associated immune cascade with guselkumab may be a safe and useful therapeutic option for treatment of PPP.Trial registrationclinicaltrials.gov Identifier: NCT01845987.

Project description:BackgroundPalmoplantar pustulosis (PPP), a refractory skin disease characterized by repeated eruptions of sterile pustules and vesicles on palms and/or soles, involves interleukin-17 pathway activation. Brodalumab, a fully human anti-interleukin-17 receptor A monoclonal antibody, is being investigated for use in PPP treatment.ObjectiveThe aim was to assess the efficacy and safety of brodalumab in Japanese PPP patients with moderate or severe pustules/vesicles.MethodsA phase 3, randomized, double-blind, placebo-controlled trial was conducted between July 2019 and August 2022, at 41 centers in Japan. Patients aged 18-70 years with a diagnosis of PPP for ≥ 24 weeks, a PPP Area Severity Index (PPPASI) score of ≥ 12, a PPPASI subscore of pustules/vesicles of ≥ 2, and inadequate response to therapy were included. Participants were randomized 1:1 to receive brodalumab 210 mg or placebo, subcutaneously (SC) at baseline, weeks 1 and 2, and every 2 weeks (Q2W) thereafter until week 16. Changes from baseline to week 16 in the PPPASI total score (primary endpoint) and other secondary skin-related endpoints and safety endpoints were assessed.ResultsOf the 126 randomized patients, 50 of 63 in the brodalumab group and 62 of 63 in the placebo group completed the 16-week period. Reasons for discontinuation were adverse event (n = 6), withdrawal by patient/parent/guardian (n = 3), progressive disease (n = 3), and lost to follow-up (n = 1) in the brodalumab group and Good Clinical Practice deviation (n = 1) in the placebo group. Change from baseline in the PPPASI total score at week 16 was significantly higher (p = 0.0049) with brodalumab (least-squares mean [95% confidence interval {CI}] 13.73 [10.91-16.56]) versus placebo (8.45 [5.76-11.13]; difference [95% CI] 5.29 [1.64-8.94]). At week 16, brodalumab showed a trend of rapid improvement versus placebo for PPPASI-50/75/90 response (≥ 50%/75%/90% improvement from baseline) and Physician's Global Assessment 0/1 score: 54% versus 24.2%, 36.0% versus 8.1%, 16.0% versus 0.0%, and 32.0% versus 9.7%, respectively. Infection was the dominant treatment-emergent adverse event (TEAE); the commonly reported TEAEs were otitis externa (25.4%/1.6%), folliculitis (15.9%/3.2%), nasopharyngitis (14.3%/4.8%), and eczema (14.3%/12.9%) in the brodalumab/placebo groups, respectively. The severity of most TEAEs reported was Grade 1 or 2 and less frequently Grade ≥ 3.ConclusionsBrodalumab SC 210 mg Q2W demonstrated efficacy in Japanese PPP patients. The most common TEAEs were mild infectious events.Trial registrationNCT04061252 (Date of Trial Registration: August 19, 2019).

Project description:ObjectiveGuselkumab, 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.MethodsAdults 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.ResultsOf 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.ConclusionIn biologic-naive PsA patients, guselkumab provided sustained improvements across diverse manifestations and maintained a favorable risk-benefit profile through week 52.

Project description:Canakinumab is a high-affinity human monoclonal anti-interleukin-1? (IL-1?) antibody of the IgG1/? isotype designed to bind and neutralize the activity of human IL-1?, a pro-inflammatory cytokine. Canakinumab is currently being investigated on the premise that it would exert anti-inflammatory effects on a broad spectrum of diseases, driven by IL-1?. This paper focuses on the analysis of the pharmacokinetic and pharmacodynamic data from the canakinumab clinical development programme, describing results from the recently approved indication for the treatment of cryopyrin-associated periodic syndromes (CAPS) under the trade name ILARIS®, as well as diseases such as rheumatoid arthritis, asthma and psoriasis. Canakinumab displays pharmacokinetic properties typical of an IgG1 antibody. In a CAPS patient weighing 70?kg, slow serum clearance (0.174?L/day) was observed with a low total volume of distribution at steady state (6.0?L), resulting in a long elimination half-life of 26 days. The subcutaneous absolute bioavailability was high (70%). Canakinumab displays linear pharmacokinetics, with a dose-proportional increase in exposure and no evidence of accelerated clearance or time-dependent changes in pharmacokinetics following repeated administration was observed. The pharmacokinetics of canakinumab in various diseases (e.g. CAPS, rheumatoid arthritis, psoriasis or asthma) are comparable to those in healthy individuals. No sex- or age-related pharmacokinetic differences were observed after correction for body weight. An increase in total IL-1? was observed in both healthy subjects and all patient populations following canakinumab dosing, reflecting the ability of canakinumab to bind circulating IL-1?. The kinetics of total IL-1? along with the pharmacokinetics of canakinumab were characterized by a population-based pharmacokinetic-binding model, where the apparent in vivo dissociation constant, signifying binding affinity of canakinumab to circulating IL-1?, was estimated at 1.07?±?0.173?nmol/L in CAPS patients. During development of canakinumab a cell line change was introduced. Pharmacokinetic characterization was performed in both animals and humans to assure that this manufacturing change did not affect the pharmacokinetic/pharmacodynamic properties of canakinumab.

Project description:BACKGROUND:Interleukin-13 (IL-13) is a key mediator of T-helper-cell-type-2 (Th-2)-driven asthma, the inhibition of which may improve treatment outcomes. We examined the safety, pharmacokinetics, pharmacodynamics, and immunogenicity of VR942, a dry-powder formulation containing CDP7766, a high-affinity anti-human-IL-13 antigen-binding antibody fragment being developed for the treatment of asthma. METHODS:We conducted a phase 1, randomized, double-blind, placebo-controlled, ascending-dose study at Hammersmith Medicines Research, London, UK, which is now complete. Healthy adults aged 18-50 years (n = 40) were randomized 3:1 to a single inhaled dose of VR942 0.5, 1.0, 5.0, 10, or 20 mg, or placebo. Adults aged 18-50 years who were diagnosed with asthma for ?6 months before screening, and had forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) values ?70% of the predicted values at screening (n = 45), were randomized to once-daily inhaled VR942 0.5 or 10 mg, or placebo (2:2:1), or VR942 20 mg or placebo (3:2), for 10 days. All participants were randomized to receive VR942 or placebo based on a randomization list prepared by an independent HMR statistician using SAS® software (SAS Institute, Cary, NC). The primary outcome was safety and tolerability of VR942 (safety population, defined as all who received at least one dose of VR942 or placebo). This study is listed on ClinicalTrials.gov (NCT02473939). FINDINGS:In the VR942 and placebo groups, treatment-emergent adverse events (TEAEs) were reported in 10/30 (33%) and 0/10 (0%) healthy participants, and in 16/29 (55%) and 9/16 (56%) participants with asthma, respectively. Mild intermittent wheezing occurred in 7 participants (VR942 20 mg, n = 4; corresponding placebo, n = 3), resolving spontaneously within 1 h. All TEAEs were mild or moderate; there were no deaths, serious adverse events, or clinically significant changes in vital signs, electrocardiograms, or laboratory parameters. There was no clinically significant immunogenicity, with only one participant with asthma considered positive for treatment-related immunogenicity for CDP7766. INTERPRETATION:This study, considered to be the only example of a dry powder anti-IL-13 fragment antibody being administered via inhalation, demonstrated that single and repeat doses were well tolerated over a period of up to 10 days in duration. Rapid and durable inhibition of fractional exhaled nitric oxide (FeNO) (secondary outcome) provided evidence of pharmacological engagement with the IL-13 target in the airways of participants diagnosed with mild asthma. These data, together with the numerical improvements observed for predose FEV1, justify further clinical evaluation of VR942 in a broader population of patients with asthma, and continue to support the development of an inhaled anti-IL-13 antibody fragment as a potential future treatment that is alternative to monoclonal antibodies delivered via the parenteral route. FUNDING:Study funding and funding for the medical writing and editorial support for preparation of the manuscript were split equally between the two study co-funders (Vectura Ltd and UCB Pharma).
