Active clinical trials for "Immunoglobulin G4-Related Disease"

This is a two-part multi-center clinical trial in participants with active IgG4-RD. Part 1 (Cohort 1a and Cohort 1B) is an open-label, dose escalation phase to determine the safety of elotuzumab for investigation in IgG4-RD. Part 2 (Cohort 2) is a randomized, placebo-controlled, double-blinded (masked) trial phase to compare the effects of elotuzumab and prednisone to elotuzumab placebo and prednisone in participants with IgG4 RD. Approximately 75 participants with active IgG4-RD will be enrolled in the overall program, 12 in Part 1 and 63 in Part 2. Randomization in Part 2: 2 to 1, with approximately forty-two participants randomized to elotuzumab plus prednisone taper, and twenty-one participants randomized to placebo for elotuzumab plus prednisone taper. The total duration of participation for each participant in this trial will be 48 weeks (11 months).

Even though glucocorticoid is the current first line medication for IgG4-RD, it is well accepted in the field that excessive dosage of GC, especially accumulative dosage, is associated with increasing organ damage. Although B cell depletion with rituximab has been verified to be an effective treatment for IgG4-RD, even without concomitant GC therapy, rituximab can increase the risk of infection during the treatment. Belimumab is an IgG1-lambda monoclonal antibody that prevents the survival of B lymphocytes by blocking the binding of soluble human B lymphocyte stimulator protein (BLyS) to receptors on B lymphocytes. Previous studies and trails suggested that the activity of B-cell mediated immunity and autoimmune responses were ameliorated after belimumab without increasing rates of adverse events when compared to standard of care . However, the efficacy and tolerability of belimumab in IgG4-RD patients have not been examined before. This randomized, control clinical trial aimed to evaluate the tolerability and the efficacy of Belimumab for maintenance treatment for IgG4-RD.

Evaluation of efficacy and safety of Baricitinib combined with glucocorticoid in patients of IgG4-related disease with eosinophilia.

This study aims to examine the efficacy and safety of obexelimab for the prevention of flare of IgG4-related disease (IgG4-RD)

Evaluation and prediction of relapse risk after glucocorticoid or immunosuppressant withdrawal in patients with stable IgG4 related disease: a prospective cohort study from china.

The aim of this clinical trial is to evaluate the safety and efficacy of zanubrutinib in treating patients with IgG4-related disease

This study aims to evaluate the efficacy and safety of inebilizumab for the prevention of flare of Immunoglobulin G4-related disease (IgG4-RD).

This is a Phase 2a, multi-center, open-label, two-arm study of approximately 25 patients with active IgG4-related disease (IgG4-RD). The two arms include (1) Experimental: rilzabrutinib with glucocorticoids and (2) Active Comparator: glucocorticoids only.

Compared with cyclophosphamide, the efficacy and safety of tofacitinib in the treatment of active IgG4-related diseases were evaluated.

IgG4-immunoglobulin-related disease (IgG4-IRD) is a relatively new pathology, characterized by intense inflammation, fibrosis, infiltration and elevated IgG4 levels in peripheral blood. Despite the interest in the disease, these diagnostic criteria are not without discrepancies and false negatives. In fact, despite the fact that elevated serum IgG4 concentrations can provide an important clue for the diagnosis of the disease,described that the specificity and positive predictive value of elevated serum IgG4 concentrations are 60 % and 34 % respectively. And, when they increased the cut-off values to double to improve specificity, the sensitivity of IgG4 levels drops to 35 %. In 2014, was described the presence of elevated concentrations of plasmablasts (CD19 low, CD20 -, CD38+ and CD27+) in the serum of patients with active ER-IgG4, even in patients with normal IgG4 levels, compared with healthy patients and with other autoimmune pathologies. Furthermore, several studies have shown that follicular T helper (Thf) cells are increased in both peripheral blood and affected tissue of patients with ER-IgG4. These cells appear responsible for the development of germinal centers in lymph nodes and for the production of interleukins that drive IgG4 class switching, and creation of IgG4-secreting plasmablasts and plasma cells. This suggests that interleukins IL4, IL5, IL 10, IL13 might also be relevant in discerning ER-IgG4 from other immune-mediated processes with similar symptoms. ACTION GOALS: To evaluate the diagnostic validity of plasmablast count and other immunological markers (B lymphocyte differentiation stage, follicular T helper lymphocytes (Thf) and IL-4, IL5, IL-10 and IL-13) in peripheral blood for IgG4-Related Disease. To evaluate the correlation of these biomarkers with inflammatory activity, clinical manifestation and diagnostic certainty (possible, probable or definite) of IgG4-Related Disease. To evaluate whether high counts or concentrations of these biomarkers at diagnosis are prognostic factors for relapse during the first 12 months of follow-up in patients with IgG4-Related Disease.
