Autoimmune Diseases

Background: Autoimmune diseases can be caused by genes people inherit from their parents. The gene changes that cause these diseases have been well studied in people with European and Asian ancestors. But some diseases behave differently in people who are native to North and South America. Researchers want to know more about the gene changes and other factors that may cause autoimmune diseases among these people. This project will be based in Peru. Objective: To study how gene changes can lead to autoimmune diseases in people native to Peru. Eligibility: People aged 18 years and older with an autoimmune disease. These may include systemic lupus erythematosus; Sjogren disease; scleroderma; rheumatoid arthritis; seronegative spondylo-arthropathies; and systemic vasculitis. Family members and healthy volunteers are also needed. Design: Participants will have 2 clinic visits; these will be 2 weeks apart. The clinics will be in Lima, Iquitos, and other sites in Peru. Visit 1: Participants will have a physical exam. They will answer questions about their health risks and habits. They will provide blood and urine samples. Visit 2: Participants will provide a second blood sample and a stool sample. They will talk about the results of their first clinical exam with researchers. The cost of travel to and from the clinics will be provided. Participants will get $30 per visit and a snack.

This Phase 2, multicenter, open-label study will evaluate the safety and efficacy of a single infusion of autologous anti-CD20/BCMA chimeric antigen receptor T cells (C-CAR168) following lymphodepleting chemotherapy in participants with refractory lupus nephritis who are not responding to standard therapy. Approximately 50 participants will undergo leukapheresis, lymphodepletion with fludarabine and cyclophosphamide, and infusion of C-CAR168. Participants will be followed for 104 weeks (approximately 2 years) to evaluate renal response, safety, CAR T-cell persistence, pharmacokinetics/pharmacodynamics, and biomarkers. Long-term safety follow-up for gene therapy-related events will continue for up to 15 years following CAR T-cell infusion.

Type 1 diabetes is an autoimmune health condition that requires daily injections of insulin. Insulin allows the body to use energy from carbohydrates in food. Disordered eating behaviours, like restricting food intake to lose body weight, are more common in women and people with type 1 diabetes, compared to those without because they must practice carbohydrate counting. Carbohydrate counting means identifying, measuring, and planning carbohydrate intake to match insulin dosage. New technologies, such as automated insulin delivery (AID) systems adjust insulin delivery in a blood sugar responsive manner. AID is rapidly replacing conventional insulin delivery like injections or non-automated insulin pumps since it reduces management burden and improves blood sugar levels. It is not known if AID reduces food management and disordered eating behaviours. This study aims to: 1. investigate the relationship between AID and eating behaviours according to gender for youth (12 to 17 years), and adults (18 years and older). 2. Determine the limit of carbohydrate counting inaccuracy to maintain stable blood sugar levels according to insulin delivery method (AID, injections, or pumps). It is hypothesized that those who use AID will have lower disordered eating behaviours and will maintain stable blood sugar levels while allowing for higher carbohydrate counting inaccuracy. This will be a cross-sectional cohort study of people with type 1 diabetes who are 12 years of age or over. Participants will be recruited through the BETTER registry and social medias across Canada. This research is needed to improve nutrition guidelines for type 1 diabetes in the context of new technologies like AID. Evidence from this study may reduce food management burden, lower the risk of disordered eating behaviours, and prevent eating disorders and medical complications.

Sjögren's syndrome is an autoimmune disease. Dry syndrome is a key feature of this condition, almost always leading to dryness of the mouth and eyes. It manifests as a decrease in the production of saliva and tears, causing discomfort for patients. This chronic dryness contributes to oral and ocular conditions. It is caused by lymphocytic infiltration of the exocrine glands, leading to their inflammation and subsequent fibrosis, which results in a decrease in fluid production by these glands. This chronic inflammation causes fatigue in the patient. Furthermore, in 30 to 60% of cases, Sjögren's syndrome may involve extra-glandular involvement, most commonly affecting the joints, but also involving the lungs, nervous system, and kidneys. Additionally, patients with thisdisease have a higher risk of developing lymphoma compared to unaffected individuals. The current treatment for Sjögren's syndrome is the same as that for dry eye syndrome; it is primarily symptomatic, involving lifestyle and dietary changes, the use of eye drops or oral lubricants, and medication to stimulate saliva production. To date, there is no medication available to treat Sjögren's syndrome and thus the cause of dry eye syndrome. In our laboratory (INSERM 1098, UMR Right), we have developed cells that suppress the immune system (immunosuppressive cells) derived from human monocytes cultured ex vivo using a patented process called HuMoSC (Human Monocyte -derived Suppressor Cells). These cells possess strong immunosuppressive capacity, already demonstrated in vitro and in vivo in mouse models. The aim of this study is to evaluate whether HuMoSCs can reduce the accumulation of immune cells and thereby decrease chronic inflammation and, in the longer term, limit the development of fibrosis (hardening with tissue destruction and scarring) in the salivary glands. Biopsy of the accessory salivary glands is already part of the diagnostic process for Sjögren's syndrome. During this biopsy, additional accessory salivary glands will be collected and sent to the laboratory for this study. These glands will be cultured in the presence of HuMoSC supernatant, and the impact of this treatment will be analyzed.

Enrollment will be distributed equally between the University of Washington and Amsterdam University Medical Center/Diabetes Center Amsterdam. Participants will be recruited through diabetes research registries, local T1D clinics, and community outreach.

Type I interferonopathies are rare autoinflammatory disorders caused by genetic defects and associated with significant morbidity and mortality. These diseases are refractory to conventional immunosuppressive therapies. They typically occur in childhood, although disease onset in adulthood has been observed. The clinical spectrum is wide and mainly involves the central nervous system. Joint involvement is also common, and more rarely, haematological features such as cytopenias or immunodeficiency may be observed. Nearly all patients show consistent over-activation of the type I IFN pathway, as evidenced, the expression of IFN-stimulated genes, the so-called 'interferon signature'. To date, the natural history of interferonopathies remains unclear. In this context, the establishment of a natural history of type I interferonopathy in patients is proposed to elucidate the pathophysiological mechanisms and identify biomarkers for diagnosis, prognosis, and disease activity, with the aim of better characterising the diversity of interferonopathies. The main objective is to characterise the evolution of the pathology in paediatric and adult patients with type I interferonopathies. The overall aim of this research is to propose therapeutic options tailored to patient phenotypes and to better define patient sub-groups in order to optimise the preparation of future clinical trials.

Many people with long-term health conditions require regular blood tests to monitor their disease or medications. These blood tests are usually performed by taking blood from a vein during a hospital or clinic appointment. This can be inconvenient, time-consuming and difficult for some people, particularly those who live far from hospital, have reduced mobility, require frequent tests, or experience anxiety about attending healthcare settings or having blood taken. Capillary blood sampling devices allow people to collect a small blood sample themselves, usually from the upper arm or fingertip, which can then be sent to a laboratory by post. These devices have shown promising results for some blood tests, but there is insufficient evidence of which tests remain accurate when samples are collected at home, posted to the laboratory and subjected to postage conditions and delayed analysis. The CAPSICUM study will compare blood samples collected using patient-operated capillary sampling devices with routine venous blood samples already being taken as part of participants' usual clinical care. We will investigate whether a wide range of blood tests produce similar results using both methods and assess how delayed analysis, postal transport and home collection affect test accuracy. Participants will attend only one study visit, which will take place during a routine clinic appointment. Some participants will also be invited to collect an additional blood sample at home and return it by post, and to complete a brief questionnaire about their experience. The findings from this study will help identify which blood tests can be safely monitored using home capillary blood sampling. This could improve access to blood monitoring, reduce unnecessary hospital visits, make monitoring more convenient for patients, and support the development of safe, evidence-based remote monitoring pathways within the NHS.

Neurological autoimmune diseases are a group of disorders characterized by the abnormal immune response attacking the nervous system, including the brain, spinal cord and peripheral nerves. These diseases exhibit high heterogeneity, diverse clinical presentations, and are challenging to diagnose and manage due to a lack of effective treatments. In this study, the investigators will recruit eight kinds of autoimmune diseases of nervous system including Neuromyelitis Optica Spectrum Disorder (NMOSD), Myasthenia Gravis (MG), Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP), idiopathic inflammatory myopathy (IIM), and multiple sclerosis (MS), autoimmune encephalitis (AE), Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease (MOGAD). Through this study, the investigators aim to discover biomarkers with high sensitivity, specificity, and stability, which can support early diagnosis, disease monitoring, and personalized treatment for neurological autoimmune diseases, thereby improving the quality of life and prognosis for patients.

This would allow to initiate, following this study, research and development programs on the use of anti-STIM1 antibodies in these identified autoimmune diseases of interest.

This is a single-arm, open-label, phase I clinical study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of RD06-05, a universal CD19/BCMA dual-targeting chimeric antigen receptor T-cell (CAR-T), in pediatric and adolescent patients with refractory autoimmune diseases, including systemic lupus erythematosus/lupus nephritis (SLE/LN), systemic sclerosis (SSc), idiopathic inflammatory myopathy (IIM), multidrug-resistant nephrotic syndrome (MDR-NS), and refractory IgA nephropathy (IgAN). Approximately 30 eligible patients will be enrolled and receive a single intravenous infusion of RD06-05 at an initial dose of 6×10⁶ CAR+ T cells/kg, with a potential dose escalation to 10×10⁶ CAR+ T cells/kg following review by a Safety Review Committee (SRC).

The plasma filter is applied for a single use in extracorporeal blood purification therapy. The intended purpose is the separation of plasma from blood by filtration, in conditions, which are associated with increased concentration of plasma components where a rapid depletion slows down or stops a pathogenic process. The investigation involves the collection of treatment data of the new Plasma Filter PX2 in combination with the multiFiltrate and multiFiltratePRO in therapeutic plasma exchange (TPE) treatments. The multiFiltrate and multiFiltratePRO are devices for extracorporeal blood purification treatments. No further control treatments will be investigated in this one arm design. The design is considered to be appropriate to reflect daily clinical practice and to contribute to empirical evidence of performance of the new Plasma Filter PX2. No specific treatment schedule is defined by the study protocol. The TPE treatment is performed with the plasma filter PX2 (investigational device) according to clinical practice established in each of the participating centers and are prescribed at the discretion of the treating physician. The participation in the study will have no influence on the treatment plan. The documentation of the treatment includes the therapy up to the tenth (10th) treatment.
