About RUXIENCE (Rituximab-pvvr)
RUXIENCE is a monoclonal antibody biosimilar to MabThera, also known as RITUXAN, which works by targeting a protein called CD20, which is present on the surface of B lymphocytes, also known as B cells. When it attaches to CD20, rituximab helps destroy these B cells. RUXIENCE is a biosimilar of Biogen’s RITUXAN. In the US, RUXIENCE is approved for treatment of Non-Hodgkin’s Lymphoma (alone or with other chemotherapy medicines), Chronic Lymphocytic Leukemia (with the chemotherapy medicines fludarabine and cyclophosphamide), and Granulomatosis with Polyangiitis and Microscopic Polyangiitis (with glucocorticoids). The product is also approved for use in Japan and received marketing authorization in the European Union in April 2020. RUXIENCE is a trademark of Pfizer; RITUXAN is a trademark of Biogen.

RUXIENCE was not developed using Aptevo’s platform technology.
