This is a two-part multi-center clinical trial in participants with active IgG4-RD.
Part 1 (Cohort 1a and Cohort 1B) is an open-label, dose escalation phase to determine the safety of elotuzumab for investigation in IgG4-RD.
Part 2 (Cohort 2) is a randomized, placebo-controlled, double-blinded (masked) trial phase to compare the effects of elotuzumab and prednisone to elotuzumab placebo and prednisone in participants with IgG4 RD.
Approximately 75 participants with active IgG4-RD will be enrolled in the overall program, 12 in Part 1 and 63 in Part 2. Randomization in Part 2: 2 to 1, with approximately forty-two participants randomized to elotuzumab plus prednisone taper, and twenty-one participants randomized to placebo for elotuzumab plus prednisone taper.
The total duration of participant follow-up in this trial will be 48 weeks (11 months).
Immunoglobulin G4-Related Disease (IgG4-RD) is a chronic fibro-inflammatory condition that can affect virtually every organ system, including the pancreas, biliary tract, salivary and lacrimal glands, orbits, lungs, kidneys, meninges, pituitary gland, prostate and thyroid. It may also involve the retroperitoneum. This multi-organ immune-mediated condition, once regarded as a group of isolated, single-organ diseases, is now recognized to be an overarching, single-disease entity linked by common histopathological and immunohistochemical features.
IgG4-RD tends to afflict middle-aged to elderly individuals. Although IgG4-RD can affect a single organ at presentation, it is not uncommon for participants to present with or develop multi-organ disease. As the disease progresses, additional organs develop lesions and the cellular inflammation characterizing early disease moves toward a more fibrotic stage, causing major tissue damage, dysfunction and ultimately organ failure. It is unclear whether IgG4 itself is involved in the pathogenesis of the disease.
The goals of IgG4-RD treatment are to reduce inflammation and organ swelling and to prevent or reverse tissue fibrosis. No approved therapy exists for IgG4-RD.
This study will enroll adult participants who meet the 2019 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) Classification Criteria for IgG4-RD, and who have active IgG4-RD with disease manifestations in at least two organ systems.
