Active clinical trials for "Autoimmune Diseases"

The purpose of this research study is to test the safety, tolerability, and effectiveness of Topical AmphiMatrix with Nitroglycerin (MQX0503) to relieve Raynaud's symptoms and increase blood flow to the fingers.

Immunoglobulin A (IgA) nephropathy is the common primary glomerulonephritis in the world. Much literature suggests that vitamin D and its analogs have profound effects on immune system function and glomerular mesangial cell proliferation. Therefore, the investigators plan to conduct a randomized clinical study to evaluate the efficacy of Calcitriol in the treatment of IgA nephropathy. Forty patients with biopsy-proven IgA nephropathy will be recruited. They will be randomized to Calcitriol for six months or no treatment. Proteinuria, renal function, serum and urinary inflammatory markers will be monitored. This study will explore the potential anti-proteinuric and anti-inflammatory effects of Calcitriol in the treatment of IgA nephropathy, which has no specific treatment at present.

SN1011 (the study drug), is currently being developed by Sinomab as a new drug for treating autoimmune disease (diseases occurring when your body's natural immune/defence mechanism attacks healthy tissue and nerves), such as rheumatoid arthritis (RA). RA causes recurrent joint pain and swelling, particularly in the hands and feet, and can lead to bone erosion and joint deformity. SN1011 is known as a BTK inhibitor. Bruton's tyrosine kinase (BTK) is an enzyme that plays a key role in B-cell development, and B-cells play an important role in immunity throughout the body. It is thought that blocking the BTK signal may inhibit disease progression in people with RA and may even resolve the disease. The purpose of this research study is to assess the safety and tolerability of SN1011 as well as the pharmacokinetics (PK - how your body handles the study drug) and pharmacodynamics (PD - how the study drug affects your body) of the study drug. The investigators are doing this study in healthy men and women.

A randomized, double-blind, placebo-controlled clinical study in human leukocyte antigen (HLA)-DQ 2.5+ adults with celiac disease (CeD).

This observational trial assesses the safety and efficacy of Gammanorm® in autoimmune diseases.

Several clinical studies have shown that rituximab is safe and effective for the induction of remission in moderate to severe systemic lupus erythematosus, and has been recommended by several guidelines for the induction of remission in refractory lupus with important organ involvement. However, there are few studies on the use of rituximab in the long-term maintenance and remission of the disease. There is no recognized scheme for the dose, interval and course of treatment of the drug. In this study, patients with moderate and severe systemic lupus erythematosus who achieved remission after standardized treatment were randomly divided into two groups at 1:1 and followed up every 3 months for 24 months. The basic situation and disease activity score of each subject were recorded. The recurrence rate of each observation group was calculated, the influencing factors of disease recurrence were analyzed, and a more reasonable drug use scheme was explored.

This study is an open-label randomized controlled trial aiming to investigate whether the efficacy and side effect of Leflunpomide plus glucocorticoid.

The purpose of the study is to evaluate if inhaled granulocyte-macrophage colony stimulating factor delay the increase in alveolar-arterial oxygen difference, compared to no treatment, for adult patients with mild-to-moderate autoimmune pulmonary alveolar proteinosis in China over a two-year period.

While glucocorticoids and immunosuppressants ameliorate manifestations of autoimmune diseases in many patients, current therapies are insufficient to control the disease in a subset of patients, and their clinical prognosis remains poor due to the development of vital organ failure, cumulative drug toxicity and to the increased risk of cardiovascular disease and malignancy. Immunoablative chemotherapy followed by autologous hematopoietic stem cell transplantation (ASCT) has recently emerged as a promising experimental therapy for severely affected patients, providing them the potential to achieve treatment-free, long-term remission. The rationale for applying ASCT to autoimmune diseases has been the hope that immunoablation could eliminate inflammation-driving pathogenic cells from the immune system, and that regeneration of the patients' immune system from hematopoietic precursors could re-establish immunological tolerance.

Pemphigus is an autoimmune disease specific to the skin and mucous membranes characterized by the production of IgG4 isotype autoantibodies (AC) directed mainly against two proteins involved in interkeratinocyte adhesion: desmoglein 1 (Dsg1 ) and desmoglein 3 (Dsg3) (1-3). The binding of auto-AC on these proteins disrupts their adhesion function, resulting in inter-keratinocyte dysjunction called "acantholysis" responsible for the formation of intraepidermal bubbles. Treatment of pemphigus is typically based on systemic corticosteroids. High doses are usually necessary because of the frequent cortico-resistance of the disease. In recent years, several studies have focused on the treatment of pemphigus with anti-CD20: rituximab. The "Ritux 3" study (NCT00784589), a randomized, multicentre, randomized, non-blind clinical trial involving 90 patients, found that the use of rituximab as first-line therapy in combination with short corticosteroid therapy was extremely effective and that cortisone sparing was thus obtained limited the occurrence of side effects of treatment. On the other hand, this study showed that the 2 rituximab maintenance infusions of 500 mg to M12 and M18 allowed the maintenance of a high rate of complete remission up to the 3rd year of follow-up. Questions remain to explain the long-term action of rituximab, in particular that of the evolution of these auto-reactive B cells (specific DSG) away from lymphocyte reconstitution B, as well as the evolution of auto-AC. anti-DSG and total IgG CAs, so as to ensure that the disappearance of the auto-reactive compartment is not accompanied by a long-term overall immunosuppression (and therefore a possible risk of infection). The immunological changes induced in the long term as well as the precise mechanism of action of these treatments and particularly rituximab which allows a complete remission 5 years after treatment in many patients remain little known.
