A Study of Efgartigimod in Patients With IgG4-Related Disease

The goal of this clinical trial is to learn if efgartigimod can treat IgG4-related disease in adults. The main questions it aims to answer are: In patients with IgG4-related disease, does treatment with efgartigimod reduce the volume of the: * lacrimal gland(s) and/or * salivary gland(s) and/or * pancreas Participants will: * Receive efgartigimod once weekly for up to 12 weeks * Visit the clinic every one to six weeks for checkups and tests * Be asked to complete questionnaires to see how they feel on efgartigimod

Drug Rediscovery for Rare Immune Mediated Inflammatory 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.

Study of Sirolimus in IgG4-related Disease

gG4-related disease (IgG4-RD) is a newly recognized systemic autoimmune disease that can involve the pan-creatobiliary tract, retroperitoneum/aorta, head and neck region, and salivary glands, et al. Glucocorticoids are the first-line agents for the treatment of IgG4-RD, however, in order to maintain long-term disease stability and avoid disease relapse, glucocorticoids maintenance therapy should last for a long period, which may induce various glucocorticoid-associated adverse reactions. Sirolimus plays dual roles in inhibiting lymphocyte activation and fibroblast proliferation. It is inferred from its mechanism that sirolimus is a good potential treatment option for IgG4-RD. Therefore, we conducted this single-arm clinical trial on patients with IgG4-RD to determine the efficacy and safety of sirolimus.

Meir Medical Center Rheumatologic Biobank

Serum, synovial fluid and skin biopsies from patients will be collected to the biobank with rheumatoid diseases. These samples will later be used for clinical and basic research, following approval of each specific study by the IRB. The investigators intend to extract protein, DNA and RNA from each sample.

A Prospective Cohort Study of IgG4RD in China

This is an cohort study to investigate the disease course and treatment response of patients with IgG4-related disease.
