Brief summary
This is a multi-center study to evaluate the safety, tolerability, PK, PD, and clinical activity of itolizumab (EQ001) in subjects with Systemic Lupus Erythematosus with or without Active Proliferative Lupus Nephritis
Detailed description
The study will enroll approximately 55 subjects, with up to 5 dose escalating cohorts of 6 open-label subjects enrolled for Type A-SLE and a single dose cohort of approximately 20 open-label subjects enrolled for Type B-Lupus Nephritis. Subjects will receive itolizumab administered subcutaneously every two weeks for a total of either 2 (Type A) or 13 (Type B) doses with 4 or 12 weeks of follow-up after the last dose of investigational product.
