Active clinical trials for "Lupus Erythematosus, Systemic"

To explore the association with TCM pattern and TCM tongue diagnosis for Autoimmune disease and Dry eye syndrome.

A prospective, single-center cohort study aims to determine a predictive model of the response of belimumab at Week 48.

Rationale: Systemic lupus erythematosus (SLE) is a chronic relapsing-remitting autoimmune disease with a wide range of clinical manifestations affecting several organs. Although the management of lupus patients has improved in the last years, accurate models for predicting disease progression are lacking. Objective: To prospectively evaluate the predictive value of a combination of chemokines, MMPs/TIMPs, and autoantibody levels for predicting flares in patients with SLE Study design: prospective, observational single centre cohort study, conducted at the department of Rheumatology and Clinical Immunology of the UMC Utrecht Study population: Adult patients with SLE (according to EULAR/ACR criteria) under control in the UMC Utrecht. Intervention (if applicable): n/a Main study parameters/endpoints: Profile of autoantibodies and chemokines in visits previous to recorded flares, compared to visits previous to no recorded flares. Risk calculations will be made using areas under the curve (AUC) for both individual markers as multivariate analysis Changes in the profile of autoantibodies and chemokines in patients with lower reported quality of life measured by LupusQoL questionnaire, compared to previous visits of the same patient. Changes in titer levels of autoantibodies before and after start of biological treatment. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: this is an observational study; the burden for patients is esteemed to be low. For some patients who regularly attend the outpatient clinic yearly, the four-times a year visits during two years will be more frequent, including more frequent blood sampling, compared to standard care. Furthermore, more blood will be drawn per sampling, compared to standard care.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by the production of multiple autoantibodies and accumulation of immune complexes resulting in systemic inflammatory response and tissue damage. Dysfunction of proteins initially known to initiate the classical pathway for complement activation (C1q and C1s), and their functional interference with the multifunctional protein HMGB1 (High-Mobility Group Box 1), appears to be associated with SLE. On the other hand, C1s, HMGB1 and C1q can be targeted by anti-C1s, anti-HMGB1 and anti-C1q autoantibodies from lupus patients, whose functional impact remains to be explored, in particular for non-canonical functions, independent of the complement activation cascade. Studies are needed to investigate the pathogenic role of these autoantibodies in SLE, including possible interference with the inactivation of HMGB1. This project plans to investigate the role of anti-C1s, anti-HMGB1 and anti-C1q autoantibodies in the pathogenesis of Systemic Lupus Erythematosus. This pilot study will be performed for 30 patients with active SLE on serum, realized for routine patient care. The investigators will identify the molecular targets recognized by anti-C1s, anti-HMGB1 and anti-C1q autoantibodies purified from the SLE patients' serum. The investigators will also explore the functional role of these purified autoantibodies.

To collect information on and evaluate the long-term safety and effectiveness of Anifrolumab in patients with systemic lupus erythematosus in the real-world post-marketing setting.

This study evaluates the variation of expression of the neonatal Fc receptor (FcRn) in Natural Killer T Cells Expressing an Invariant T Receptor (iNKT) and monocytes along with the surface expression of Fc gamma type II receptor (RII) and RIII in active or newly diagnosed lupus patients compared to inactive lupus patients.

Anifrolumab Study of Treatment Effectiveness in the Real World (ASTER) study will collect real world data to obtain a good understanding of the (sustained) clinical effect and patient quality of life outcomes among diagnosed SLE patients who initiate anifrolumab treatment. ASTER will generate critical real-world evidence on the benefits of adding anifrolumab to standard of care treatment for SLE in routine clinical practice, to inform physicians, payers and patients.

A variant of the TNFSF13B gene, commonly referred to as BAFF-var has been associated with an increased risk of developing immune-mediated diseases, such as Systemic Lupus Erythematosus (SLE) and Rheumatoid Arthritis (RA). This polymorphism leads to the production of higher levels of BAFFs, that in turns are associated with more severe disease, high anti-Sm and anti-dsDNA titre, complement consumption, and increased risk of flare in SLE, and higher disease activity in RA. This is a prospective study aiming to explore the immunological basis of a potential role of BAFF-var as a prognostic biomarker for response to belimumab and rituximab, the main B-depletive treatments, in SLE and RA patients, respectively. More in detail, the study aims to evaluate if the condition of BAFF-var carrier in SLE and RA patients, treated respectively, with belimumab plus standard of care or rituximab influences immunological, molecular and clinical variables, such as: (a) soluble BAFF (BAFFs) cytokine, (b) mRNA-BAFF (c) miRNA-15a (d) B-cell subpopulations (d) disease activity, as assessed by standardized clinimetric tools.

Study Description: Systemic lupus erythematosus (SLE) occurs predominantly in women and is driven by type I interferon dysregulation and neutrophil hyperresponsiveness. Neutrophils in females have reduced mitochondrial bioenergetic capacity which affects immunometabolism. Nicotinamide adenine dinucleotide (NAD)+ boosting with nicotinamide riboside blunts type 1 IFN activation in-vivo in monocytes of healthy subjects and ex-vivo in SLE subjects. These findings support the proposal of the hypothesis that NAD+ boosting by NR supplementation will modulate metabolic pathways in lupus and blunt type 1 interferon signaling. Moreover, as type 1 interferon drives endothelial dysfunction, linked to increased cardiovascular risk, the effect of NR on endothelial function will be examined. Objectives: Primary Objective: Evaluate the effect of NR vs. placebo on immunometabolic and inflammatory remodeling in female SLE subjects: Exploratory Objective: Compare and characterize myeloid cell bioenergetic and immunometabolic profiles in healthy control and SLE female subjects Endpoints: Primary Endpoint: The primary end point will be to assess the effect of NR on blunting type I IFN signaling by measuring monocytic secretion of IFN-beta secretion compared to baseline in response to placebo vs. NR supplemented in SLE study subjects. Exploratory Endpoints: Healthy control vs. SLE subjects: Compare type I IFN transcript profiles in monocytes and neutrophils at baseline and in response to activation. Assess cell bioenergetics including: 1) monocyte and neutrophil metabolic flux mass spectroscopy of 13C-glucose and 13Cglutamine analysis to investigate their metabolic fates; (iii) Mitochondrial oxygen consumption (using glucose, amino acid, and fatty acid substrates) and glycolysis rates. SLE baseline vs. NR/placebo supplementation: Baseline vs. 6 weeks of NR/placebo: -Assess effect of NR on bioenergetics by measuring steady-state metabolite levels comparing changes in placebo vs. NR groups in monocytes and neutrophils. Baseline vs. 12 weeks of NR/placebo: Whole blood NAD+ levels (batched and measured at the end of study enrollment period) Explore effects of NR on gene regulation using monocyte and neutrophils by RNA-seq and chromatin remodeling analysis. Determine the effect of NR vs placebo on endothelial dysfunction in SLE subjects

This is a Phase II study to evaluate the safety, tolerability and manufacturing feasibility of Descartes-08 CAR T-cells in patients with Systematic Lupus erythematosus (SLE).
