New drug combo aims to tame rare inflammatory disease
NCT ID NCT07068165
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding lenalidomide to standard steroid treatment can better control active IgG4-related disease (IgG4-RD), a rare condition that causes swelling and damage in organs. About 198 adults will receive either lenalidomide plus prednisone or prednisone alone for up to 52 weeks. The main goal is to see if the combination lowers the chance of the disease flaring up again.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- lenalidomide (a drug that modifies the immune system) combined with prednisone (a steroid)
- What this could lead to
- If successful, this could offer a new treatment option for people with active IgG4-related disease, potentially reducing relapses and allowing lower steroid doses.
- What could go wrong
- This is a mid-stage trial with only 198 participants, so results may not apply to everyone. Lenalidomide has known side effects like low blood counts and increased infection risk.

Inclusion Criteria: 1. Patients aged between 18 and 75 years who meet the 2019 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria for IgG4-RD; 2. Patients with active disease: For patients with initial treatment or relapse after drug withdrawal, active disease is defined as having an IgG4-RD Response Index (RI) of at least 2 points in at least one organ at the time of screening; for those experiencing relapse while on treatment, active disease is defined as having an IgG4-RD RI of at least 3 points in at least one organ at the time of screening; 3. Patients with the clinical subtype of proliferative IgG4-RD; 4. Patients who have no plans for pregnancy within the next 18 months and who agree to use reliable contraceptive measures during the study period; Exclusion Criteria: 1. IgG4-RD patients with only fibrotic features; 2. Absolute neutrophil count \<1.5×10\^9 /L or platelet count \<100×10\^9/L; 3. Creatinine clearance less than 60 ml/ min; 4. Liver function Child-Pugh grade B or above; 5. Chronic active infection requiring systemic treatment; 6. Diagnosed with malignant tumor in the past five years; 7. Patients with a history of thrombosis; 8. Using biological agents within six months; 9. Known to be allergic to lenalidomide or thalidomide; 10. Pregnant or lactating women; 11. Patients with any other medical conditions or for specific reasons judged by the investigator to be ineligible to participate in the study.
