Filter by:An exploratory clinical study of the safety and efficacy of YTS109 cell injection in subjects with recurrent/refractory autoimmune disease
This study is a preliminary investigation, with a single-group design, not randomized and transparent, focusing on treatment. Its purpose is to identify the highest dose of BH002 injection (CD19-BCMA CAR-T cells) that patients suffering from resistant systemic lupus erythematosus can tolerate.
Idiopathic inflammatory myositis (IIM), also known as myositis, are a heterogeneous group of diseases characterized by chronic inflammation of striated muscles and skin, with different clinical manifestations, treatment responses, and prognosis. This project will build a clinical follow-up cohort for idiopathic inflammatory myositis (IIM) centered on Renji Hospital, Shanghai Jiao Tong University School of Medicine, to promote the clinical and pathogenesis of this group of diseases.
Research into novel therapies for rare, immune-mediated inflammatory diseases (IMIDs) is limited due to small patient populations. Patients with Behçet's disease (BD), idiopathic inflammatory myopathy (IIM, also known as myositis) and IgG4-related disease (IgG4-RD) are treated with high-dosed glucocorticoids, methotrexate, azathioprine and mycophenolate mofetil, mostly for long periods of time with attendant risks of long-term toxicity, including infections. Therefore, there is an urgent need for new, more specific anti-inflammatory therapies such as targeted synthetic and biological disease-modifying antirheumatic drugs. Due to the role of type 1 interferon in both BD, IIM and IgG4-RD, JAK-STAT inhibition may be a promising treatment strategy in these conditions, because JAK1 is critical for the signal transduction of pro-inflammatory cytokine receptors. Previous research showed that JAK1 inhibition reduces activation of type 1 interferon-regulated proteins and key chemokines that control tissue inflammation.
This study will evaluate the safety and efficacy of empasiprubart compared with placebo in adult participants with dermatomyositis (DM).
The purpose of this study is to assess the safety, tolerability, and clinical activity of KYV 101 (a fully-human anti-CD19 CAR T-cell therapy) in adult subjects with B cell-driven autoimmune diseases. The trial anticipates enrolling participants to reach a maximum of 24 participants who will receive 1 dose of KYV-101 and will be followed for 2 years.
Antisynthetase syndrome (ASyS) is a rare and heteregeneous overlapping connective tissue disease, characterized by myositis, interstitial lung disease (ILD), joint involvement, Raynaud's phenomenon and cutaneous manifestations ("mechanic's hands"). Over 50% of patients develop ILD, which is the leading cause of death. The role of neutrophils - innate immune cells involved in inflammatory processes and induced in particular by cytokines of the Th17 pathway - during AS is unknown. Direct pathogenic role of neutrophils has been described during idiopathic inflammatory myopathies, with an increase of netosis correlated with disease activity and muscle damage. During ASyS, a higher number of alveolar neutrophils has been observed in patients with rapidly progressive ILD. There are few data on the specific evaluation of circulating neutrophils in ASyS. Investigators suppose that circulating neutrophils level could represent a simple and accessible severity biomarker in patients with ASyS. The main objective is to evaluate the diagnostic performance of the circulating neutrophils level (> 7000/mm3) at diagnosis on ASyS severity. The secondary objectives are: - to define a threshold for circulating neutrophils levels at diagnosis allowing to predict ASyS severity and to assess the diagnostic performance of this threshold. - to study the correlation between the level of circulating neutrophils and ASyS severity at diagnosis of the disease. - to compare the circulating neutrophils level at ASyS diagnosis and after 1 year of treatment. - to compare patients characteristics according to ASyS severity at diagnosis. - to compare BAL fluid neutrophils level according to ILD severity at ASyS diagnosis in patients with ILD.
Antisynthetase syndrome (AS) is a rare overlapping myositis characterized by cellular and humoral autoimmune responses directed against aminoacyl-tRNA synthetases. Intesrtitial lung disease (ILD) is a leading cause of mortality in antisynthetase syndrome. Recently, antigen-specific IFN-γ+ CD4+ T cells have been identified in bronchoalveolar fluid (BAL) of patients with antisynthetase syndrome and ILD. Elevated levels of IL1β, IL12, IL18, TNFα, IL17A, IL22 have also been detected in peripheral blood of AS patients, especially those with progressive ILD. Implication of innate lymphoid cells (ILC) and mucosal-associated invariant T cells (MAIT) have not yet been studied in patients with AS. Targeted therapies against Th1 and Th17 cells may represent a promising treatment in patients AS patients with ILD. Investigators suppose that antigen-specific Th1 and Th17 cells, ILC and MAIT at ILD diagnosis are associated with ILD severity at diagnosis and could predict treatment response at 6 months. The main objective is to study the correlation between BAL antigen-specific Th1 and Th17 cells at ILD diagnosis and clinical evolution after 6 months of treatment according to initial ILD severity.
Adult patients with suspected or confirmed idiopathic inflammatory myopathy (IIM) will be recruited. Patients will be approached, consented, have baseline demographics, diagnostics and disease activity measures recorded, and blood taken. The collection of data and biological material will mirror usual clinical practice as far as possible. Subjects will ideally attend further visits at 3, 6 and 12 months to have bloods taken, outcome measures recorded and questionnaires completed.In addition, blood, muscle biopsies and imaging undertaken as part of usual care will also be collected for research purposes to measure a number of biomarkers for the assessment of diagnostic accuracy and clinical utility evaluation. As per usual practice, a muscle biopsy will be performed at baseline, and a further biopsy offered at 6 months to assess treatment response. A magnetic resonance (MR) muscle protocol will also be performed as per usual clinical practice, and a gadolinium-enhanced MR heart scan offered. Both these scans will be repeated at 6-12 months. An existing electronic database entry system will be used for data entry and capture on an anonymised basis.
