Comparing glucocorticoids alone versus with MMF for IgG4-related disease

Comparison of Short-term Glucocorticoid Monotherapy and Short-term Glucocorticoid Combined with Mycophenolate Mofetil in the Treatment of IgG4 Related Disease

Not applicable Interventional Peking Union Medical College Hospital · NCT06663618

This study is testing whether adding a medication called Mycophenolate mofetil to glucocorticoids helps people with IgG4-related disease feel better compared to just using glucocorticoids alone.

What this trial studies

This study is a monocenter, 72-week prospective, randomized controlled trial that aims to compare the effectiveness of short-term glucocorticoid monotherapy against a combination of short-term glucocorticoids and Mycophenolate mofetil (MMF) in treating IgG4-related disease. Patients aged 18 to 80 who meet specific diagnostic criteria for IgG4-RD will be enrolled, and their responses to the two treatment regimens will be evaluated over the study period. The goal is to determine if the combination therapy offers any advantages over glucocorticoid monotherapy in managing this condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 80 diagnosed with active IgG4-related disease.

Not a fit: Patients with other autoimmune diseases, severe organ complications, or active infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients with IgG4-related disease.

How similar studies have performed: Other studies have explored glucocorticoid treatments for autoimmune diseases, but this specific combination approach for IgG4-RD is relatively novel.
