Eldelumab [Anti-IP-10] Induction Therapy for Ulcerative Colitis: A Randomised, Placebo-Controlled, Phase 2b Study.

ABSTRACT: BACKGROUND AND AIMS:Interferon-?-inducible protein-10 [IP-10] mediates immune cell trafficking from the circulation to the inflamed colon and decreases gut epithelial cell survival. IP-10 expression is increased in patients with ulcerative colitis [UC]. We report efficacy and safety results from a dose-ranging induction study of eldelumab, a fully human monoclonal antibody to IP-10, in moderately to severely active UC. METHODS:A total of 252 adults with UC [Mayo score ? 6 and endoscopic subscore ? 2] were randomised 1:1:1 to placebo or eldelumab 15 or 25 mg/kg administered intravenously on Days 1 and 8 and every other week thereafter. The primary endpoint was clinical remission [Mayo score ? 2; no individual subscale score > 1] at Week 11. Key secondary endpoints included Mayo score clinical response and mucosal healing at Week 11. RESULTS:Neither eldelumab 15 or 25 mg/kg resulted in significant increases vs placebo in the proportion of patients achieving Week 11 clinical remission. Remission and response rates were 17.6% and 47.1% with eldelumab 25mg/kg, 13.1% and 44.0% with eldelumab 15mg/kg, and 9.6% and 31.3% with placebo. Clinical remission and response rates were higher in anti-tumour necrosis factor [TNF]-naïve patients treated with eldelumab compared with placebo. Eldelumab treatment was well tolerated and no immunogenicity was observed. CONCLUSIONS:The primary endpoint was not achieved with induction treatment with eldelumab 15 or 25 mg/kg in patients with UC. Trends towards clinical remission and response were observed in the overall population and were more pronounced in anti-TNF naïve patients. Eldelumab safety signals were consistent with those reported previously [ClinicalTrials.gov number, NCT01294410].

Project description:Matrix metalloproteinase-9 is a proteolytic enzyme whose expression is increased in ulcerative colitis.To evaluate the safety and efficacy of GS-5745, a fully humanised anti-matrix metalloproteinase-9 monoclonal antibody, in moderately-to-severely active ulcerative colitis.We randomised 74 patients with ulcerative colitis to treatment with single or multiple ascending intravenous or subcutaneous doses of GS-5745 or placebo. Multiple-dose cohorts received either IV infusions (0.3, 1.0, 2.5 or 5.0 mg/kg GS-5745 or placebo) every 2 weeks (three total IV infusions) or five weekly SC injections (150 mg GS-5745 or placebo). The primary outcomes were the safety, tolerability and pharmacokinetics of escalating single and multiple doses of GS-5745. Exploratory analyses in the multiple-dose cohorts included clinical response (?3 points or 30% decrease from baseline in Mayo Clinic score and ?1 point decrease in the rectal bleeding subscore or a rectal bleeding subscore ?1) and clinical remission (a complete Mayo Clinic score ?2 with no subscore >1) at Day 36. Biological effects associated with a clinical response to GS-5745 were explored using histological and molecular approaches.Twenty-three of the 42 patients (55%) receiving multiple doses of GS-5745 had adverse events, compared with 5/8 patients (63%) receiving placebo. GS-5745 showed target-mediated drug disposition, approximately dose-proportional increases in maximum plasma concentration and more than dose-proportional increases in the area under the plasma drug concentration-time curve. Clinical response occurred in 18/42 patients (43%) receiving GS-5745 compared with 1/8 patients (13%) receiving placebo. Clinical remission occurred in 6/42 patients (14%) receiving GS-5745 and 0/8 (0%) receiving placebo. Patients with a clinical response to GS-5745 had reductions in matrix metalloproteinase-9 tissue levels (mean 48.9% decrease from baseline compared with a mean 18.5% increase in nonresponders, P = 0.008) significant improvements in histopathology scores (confirmed with three separate histological disease activity indices), as well as changes in colonic gene expression that were consistent with reduced inflammation.This phase 1 trial provides preliminary evidence for the safety and therapeutic potential of GS-5745 in the treatment of ulcerative colitis.

Project description:BackgroundDupuytren's disease is a common fibrotic condition that causes the fingers to flex irreversibly into the palm. Treatments for late-stage disease all have limitations, and there is no approved treatment for early-stage disease. We identified tumour necrosis factor as a therapeutic target in Dupuytren's disease, and in a dose ranging trial found 40 mg adalimumab in 0·4 mL to be most efficacious. Here we aimed to assess the effects of intranodular injection of adalimumab in early-stage disease.MethodsIn this phase 2b, randomised, double-blind, placebo-controlled trial adults with early-stage Dupuytren's disease and an established clinically distinct nodule with a clear history of progression in the preceding 6 months were recruited from two clinical centres in the UK and were randomly assigned 1:1 to receive four injections of adalimumab or saline every 3 months. Participants and assessors were masked. The primary outcome was nodule hardness measured with a durometer at 12 months. Data were analysed by linear mixed effects regression models in the intention-to-treat population with multiple imputation for missing primary outcome data. The trial is registered at the ISRCTN registry, ISRCTN 27786905 and is complete.FindingsBetween Feb 17, 2017, and Jan 11, 2019, 284 participants were screened in the UK and 140 were enrolled. 47 (34%) participants were female and 93 (66%) were male. Mean age of participants was 59·7 years (SD 10·0). Primary outcome data were available from 113 participants. Nodule hardness was lower (-4·6 AU [95% CI -7·1 to -2·2], p=0·0002) in the adalimumab compared with the saline group at 12 months. There were no related serious adverse events; the most common adverse events were minor injection site reactions.InterpretationIntranodular injections of adalimumab in participants with early-stage Dupuytren's disease resulted in softening and reduction in size of the nodules. Longer follow-up would be required to assess the effect of tumour necrosis factor inhibition on disease progression, extension deficit and hand function.

Project description:ObjectiveTumour necrosis factor signalling via the receptor-interacting protein kinase 1 (RIPK1) pathway regulates colonic inflammation suggesting that RIPK1 inhibition may be a potential therapeutic target in ulcerative colitis (UC). This phase IIa, randomised, double-blind experimental medicine study investigated the safety, pharmacokinetics (PK), pharmacodynamics (PD) and preliminary efficacy of the RIPK1 inhibitor GSK2982772 in patients with active UC.DesignIn part A, prior to a protocol amendment, one patient was randomised to receive GSK2982772 60 mg twice daily for 42 days. After the amendment, patients were randomised 2:1 to receive GSK2982772 60 mg or placebo three times daily for 42 days. In part B, all patients switched to open-label GSK2982772 60 mg three times daily for 42 days. Safety, PK, PD biomarkers, histological disease activity, clinical efficacy and quality of life were assessed at days 43 and 85.ResultsThirty-six patients were randomised (n=12, placebo/open-label GSK2982772; n=24, GSK2982772/open-label GSK2982772). Most adverse events were mild, with headache reported the most frequently across groups (placebo/open-label GSK2982772, n=2 (17%); GSK2982772/open-label GSK2982772, n=8 (33%)). GSK2982772 was well distributed into colonic tissue, with generally higher concentrations in colonic biopsy samples versus plasma. No apparent differences between treatment groups were observed for PD, histological disease activity, clinical disease activity or quality-of-life measures. At screening, all patients had Mayo endoscopic scores of 2 or 3. At day 43, no patients in the placebo/open-label GSK2982772 group achieved Mayo endoscopic scores of 0 or 1 vs 3/24 (13%) for GSK2982772/open-label GSK2982772. At day 85, 1/9 (11%) achieved scores of 0 or one for placebo/open-label GSK2982772 vs 3/22 (14%) for GSK2982772/open-label GSK2982772.ConclusionGSK2982772 was generally well tolerated, with no treatment-related safety concerns identified. However, no significant differences in efficacy were observed between treatment groups, suggesting that GSK2982772 as monotherapy is not a promising treatment for patients with active UC.Trial registration numberNCT02903966.
