People living with Systemic autoimmune rheumatic diseases (SARDs) face a new and urgent dilemma: immunosuppression increases risk for worse COVID-19 infection, yet an immune stimulation, such as vaccination, could re-activate their disease. Fear of vaccine-related disease reactivation is not of concern in other immunosuppressed groups (e.g. patients receiving chemotherapy or hemodialysis) but in SARDs, disease flare could lead to organ failure or even death. Specific research in this population is therefore critical. Moreover, among SARD patients, those on anti-CD-20 monoclonal antibody (mAb) (i.e. rituximab (anti-CD-20 mAb)), a medication used to treat inflammatory types of arthritis, have extremely low immunity post-COVID-19 mRNA vaccine. This study will test the hypothesis that a booster dose of a COVID-19 vaccine is safe and enhances post-vaccine humoral and cellular responses in SARDs patients on anti-CD-20 mAb treatment. The magnitude of this response depends on the type of COVID-19 vaccine administered and is optimal when the booster dose is a vaccine from a different group than the one used for primary immunization (mix-and-match approach).
This will be the first-in-human study designed to evaluate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of single ascending doses of DS-7011a in healthy participants.
The purpose of this two-part multiple ascending dose study is to evaluate the safety and tolerability of multiple doses of MHS552 in adults with mild to moderately active Systemic Lupus Erythematosus (SLE). Participants will be treated for 4 or 12 weeks followed by an 8-week follow-up period.
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.
Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder characterized by production of autoantibodies directed against nuclear and cytoplasmic antigens. Clinically, this disorder is characterized by periods of remission and relapse (1). The early and accurate diagnosis of SLE is challenging (2). The SLE pathogenesis involves multiple cellular components of the innate and immune systems, presence of autoantibodies and immune complexes, engagement of the complement system and cytokine dysregulation (3). About 180 autoantibodies have been identified in SLE patients, 102 of which are reported to have an organ-specific correlation with SLE disease identified in SLE patients, with SLE disease activity (4). However, with the exception of autoantibodies such as antinuclear antibody (ANA), anti double stranded DNA (dsDNA), anti-smith and antiphospholipid antibodies, currently proposed by the American college of rheumatology (ACR) (5)
The purpose of this Proof of Concept (PoC) and Dose-finding (DF) basket study is to evaluate the efficacy and safety of orally administered Enpatoran over 24 weeks in systemic lupus erythematosus (SLE) and cutaneous lupus erythematosus (CLE; subacute cutaneous lupus erythematosus [SCLE] and/or discoid lupus erythematosus [DLE]) participants in a randomized, double-blind, placebo-controlled, parallel, adaptive and dose-ranging setting. Study Duration: 33 weeks Visit Frequency: every 2 or 4 weeks Enpatoran is not available through an expanded access program.
This interventional study aims to investigate the effect of deep breathing (DB) and transcutaneous electrical vagus nerve stimulation (tVNS) on heart rate variability (HRV) in healthy participants and patients with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE). HRV is used as a surrogate measure of vagal nerve tone. The study consists of three sub-projects: Sub-project 1: To compare the effect of one session of DB and one session of non-invasive auricular tVNS on vagal nerve tone measured by HRV in healthy participants and in patients with RA and SLE. The hypotheses is that DB has a similar effect on HRV as non-invasive electrical tVNS. Sub-project 2: A dose-response study in healthy participants comparing the effect of 5, 15 and 30 minutes of DB on HRV. The hypothesis was that HRV increases as a function of the number of minutes the DB is performed in healthy participants. Sub-project 3: To investigate the effect of the optimal dose found in sub-project 2 in patients with RA and SLE measured by HRV, and to investigate its reproducibility by doing it twice.The hypothesis was that HRV increases after DB in patients with RA and SLE, and the effect is reproducible. In all three sub-projects the washout period will be investigated by measuring HRV three times after the intervention. We hypothesise that the effect of DB and tVNS on HRV decreases over time.
This study will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of mosunetuzumab in participants with systemic lupus erythematosus (SLE).
Accelerated atherosclerosis in patients with systemic lupus erythematosus (SLE) is not fully explained by Framingham risk factors. The detection in asymptomatic patients of somatic mutations in genes involved in hematopoietic malignancy- defining clonal hematopoiesis of indeterminate potential (CHIP) - predisposes to cardiovascular events (CVE) in general population. We aimed to determine whether CHIP is associated with CVE in SLE.
