Filter by:Systemic SClerosis (SSC) is a systemic disease characterized by limited or diffuse cutaneous sclerosis, microangiopathy, overproduction of autoantibodies and variable organ damage due to vasculopathy and/or fibrosis. The loss of self-tolerance is believed to be caused by the dysregulation of both innate and adaptive immune systems and may involve Reactive Oxygen Species (ROS). Neutrophils are potent producers of ROS and may play a role in endothelial cells and fibrobasts dysfunction, as in autoantibodies generation. However, their role in SSC pathogenesis remains to be determined. Recent studies discovered abnormal regulation of Neutrophil Extracellular Traps (NETs) in other auto-immune diseases such as Systemic Lupus Erythematosus (SLE). NETs are web-like structures composed of chromatin backbones and granular molecules. They are released by activated neutrophils through a process called "NETosis". Nets were first described in 2004 as a novel host defense mechanism to trap and kill foreign pathogens. Recent evidence shows that NETs also participate in the pathogenesis of a variety of inflammatory and autoimmune diseases, including SLE. The investigators recently highlighted this phenomenon in SSc, especially in patients with vascular complications and/or at a early stage of the disease. The investigators will now explore the factors implicated in this dysregulation of NETosis in SSc.
The goal of Safety Lead-In is to confirm the safety of tafasitamab when given to patients with SSc, SLE, and LN. The goal of Phase 1 is to find the recommended dose of AD-PluReceptor-NK cells in combination with tafasitamab and lymphodepleting chemotherapy that can be given to patients with the disease. The goal of Phase 2 is to learn if the dose of AD-PluReceptor-NK cells found in Phase 1 in combination with tafasitamab and lymphodepleting chemotherapy can help to control the disease.
This is an investigator-initiated trial to evaluate the safety and efficacy of anti- CD19-CAR-T cells in the relapse or refractory autoimmune diseases.
To evaluate the safety of UTAA09 injection in the treatment of relapsed/refractory (R/R) autoimmune disease (AID). To evaluate the pharmacokinetic (PK) profile of UTAA09 injection in patients with R/R AID. To evaluate the pharmacodynamic (PD) characteristics of UTAA09 injection in patients with R/R AID. To evaluate the initial efficacy of UTAA09 injection in the treatment of R/R AID subjects. To evaluate the immunogenicity of UTAA09 injection in R/R AID subjects.
Relma-cel is a product containing CD19-CAR-transduced T cells. The purpose of this study is to evaluate the safety of Relma-cel at different dose levels in patients with early diffuse systemic sclerosis. Efficacy will be explored too. If enrolled, participants will undergo leukapheresis, lymphodepleting chemotherapy and administration of Relma-cel.
Systemic sclerosis (SSc) is a complex systemic autoimmune disease with variable phenotype and prognosis. Autoantibodies are important diagnostic biomarkers in SSc. More than 90% of patients with SSc had anti-nuclear antibodies. Autoantibodies specific to SSc (anti-topoisomerase I antibodies, anti-centromeres, anti-RNA polymerase III, anti-Th/To, anti-fibrillarin, anti-NOR90) or associated with overlap syndromes (anti-RNA polymerase III antibodies -PM/Scl, anti-KU, anti-U1RNP, anti-TRIM21) are detected in most patients. Excluding anti-TRIM21 antibodies, autoantibodies are usually mutually exclusive and are associated with distinct phenotypes. Around 5 to 10% of patients with SSc have no autoantibodies detectable with routine biological tests. Recently, new autoantibody specificities have been described in SSc (anti-eIF2B, anti-RuvBL1/2, anti-BICD2, anti-U11/U12 RNP antibodies). "Seronegative" patients could represent new specificities of autoantibodies (unknown or not currently routinely evaluated) associated with different phenotypes of the disease. Primary objective is to compare the phenotype of patients with systemic sclerosis with or without detectable specific or associated autoantibodies. Secondary objectives are: - to determine homogeneous groups of patients with systemic sclerosis without detectable specific or associated autoantibodies - to compare the phenotype of patients with systemic sclerosis without detectable specific or associated autoantibodies according to anti-nuclear antibodies status
A Study of Anti-CD19 Chimeric Antigen Receptor T Cell Therapy for Subjects with Systemic Sclerosis
An exploratory clinical study of the safety and efficacy of YTS109 cell injection in subjects with recurrent/refractory autoimmune disease
Sharing research results with patients is required by ethical regulations. Yet, most researchers do not share results from their studies with patients. The investigators plan to conduct a series of randomized controlled trials among people with scleroderma, a rare autoimmune disease, in a large international cohort, to identify the most effective methods for communicating study results with patients. The first trial in the series will compare a research dissemination tool (infographic) against a plain-language summary comparator. Participants will be randomly assigned to receive the dissemination tool or comparator. Study participants will rate communication tools for (1) information completeness; (2) understandability; and (3) ease of use of format. Our results can be used by researchers and patient organizations who disseminate research results so that they can tailor the way they disseminate results to patient needs.
This is an investigator-initiated trial to evaluate the safety and efficacy of anti-CD19-CD3E-CAR-T cells in the relapse or refractory autoimmune diseases.
