Dermal priming to boost flu vaccine response in people on B cell depletion
This study tests whether applying a topical cream with imiquimod on the skin around vaccination can boost the body’s response to the flu shot in people who are receiving B cell–depleting therapy.
-
FAPI‑74 PET/CT versus FDG PET/CT for inflammation in FUO, IgG4‑RD, and axial spondyloarthritis
This project will test whether [18F]-AlF-FAPI-74 PET/CT finds inflammation more accurately than standard [18F]-FDG PET/CT in people with fever of unknown origin, IgG4‑related disease, or axial spondyloarthritis.
-
Anti-BCMA-CD19 CAR-T therapy for relapsed or refractory IgG4-related disease
This trial will test a personalized CAR-T cell therapy that targets BCMA and CD19 in adults (18–75) whose IgG4-related disease has come back or not responded to standard treatments like steroids or rituximab.
-
Comparing low- and higher-dose lenalidomide plus prednisone versus prednisone alone for active proliferative IgG4‑related disease
This 52-week randomized trial will test whether adding 5 mg or 10 mg lenalidomide to prednisone helps adults with active proliferative IgG4‑related disease do better than prednisone alone.
-
ACE1831 cell therapy for safety, effectiveness, and persistence in people with IgG4-related disease
This trial will test ACE1831, an off-the-shelf gamma delta T cell therapy from healthy donors, to see if it is safe and helps adults with active IgG4-related disease.

Identifying immune responses in a specific fibrotic disease
This study is looking into how the immune system works in people with IgG4-related disease to find out what specific proteins might be causing the unusual immune responses, which could help improve treatments for patients like you.
