Study of IFX-1 to Replace Steroids in Patients With Granulomatosis With Polyangiitis and Microscopic Polyangiitis.


Brief description of study

The purpose of the study is to evaluate the efficacy of IFX-1 treatment as replacement for glucocorticoid (GC) therapy in subjects with GPA and MPA.

Detailed Study Description

AAV is a group of potentially life-threatening autoimmune diseases. Preclinical data demonstrate that primed neutrophils are activated by ANCA and generate C5a that engages C5a receptors on neutrophils. Patients with ANCA-related disease have elevated plasma and urine levels of C5a in active disease but not in remission. IFX-1 is as a monoclonal antibody specifically binding to the soluble human complement split product C5a, which results in nearly complete blockade of C5a induced biological effects. Therefore, IFX-1 may be effective in the treatment of subjects with AAV.

In this Phase II study of 20 to 81 subjects with GPA or MPA, IFX-1 will be administered in combination with reduced dose glucocorticoids or a placebo glucocorticoid compared with standard dose glucocorticoids.
