What this trial studies

This observational study evaluates the efficacy and safety of tofacitinib compared to cyclophosphamide in inducing remission in patients with active IgG4-related disease. It is a prospective, single-center, non-randomized, controlled, open-label study where patients receive either glucocorticoids combined with tofacitinib or glucocorticoids combined with cyclophosphamide. The study aims to enroll at least 20 patients in each treatment group over a 6-month period, assessing remission rates and other clinical outcomes.

Who should consider this trial

Good fit: Ideal candidates are patients diagnosed with active IgG4-related disease who meet specific inclusion criteria.

Not a fit: Patients with IgG4-related diseases that threaten organ function or life, or those with certain medical histories, may not benefit from this study.

Why it matters

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

How similar studies have performed: While this approach is being evaluated, similar studies have shown promise in treating autoimmune diseases with targeted therapies.
