Detailed Description
Systemic lupus erythematosus (SLE) is an autoimmune disease with multisystemic organ involvement that is often fatal. SLE is subcategorized as extrarenal lupus (ERL) or lupus nephritis (LN). B cell depletion therapies have played an important role in the treatment of multiple B cell-driven autoimmune diseases. Subjects included in this trial will be subjects with diagnoses of systemic lupus erythematosus (SLE) including lupus nephritis (LN) and extrarenal systemic lupus erythematosus (ERL), or anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) (including Granulomatous Polyangitis and Microscopic Polyangiitis) who have refractory disease, have relapsed and have not shown appropriate clinical responses following prior systemic treatments. This study is being conducted to evaluate the safety and efficacy of an investigational cell therapy, SC291, that can be given to patients with LN, ERL or AAV, in separate parallel cohorts, who have active disease. A single dose of SC291 will be evaluated in patients who are pretreated with a standard regimen including cyclophosphamide (CY) and fludarabine (FLU).
