New hope for IgG4 patients: which drug combo works best?
NCT ID NCT05789030
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests two treatment plans for people with IgG4-related disease affecting superficial organs like glands or skin. One group gets prednisone plus iguratimod, the other gets prednisone plus leflunomide. Over 12 months, researchers will track how many patients have a relapse and how long it takes for symptoms to return. The goal is to find a safer, more effective way to keep the disease under control.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- prednisone plus iguratimod or prednisone plus leflunomide
- What this could lead to
- If successful, this could identify a more effective and safer drug combination to control IgG4-related disease and reduce relapses.
- What could go wrong
- This is a small, early-stage trial with only 60 participants, so results may not apply to all patients. Both treatments involve steroids and immune-suppressing drugs, which can have side effects.
