Among its other key offerings is ADUHELM, specifically developed for Alzheimer's disease. The company also markets a selection of biosimilar drugs, including BENEPALI (an etanercept biosimilar akin to ENBREL), IMRALDI (an adalimumab biosimilar comparable to HUMIRA), and FLIXABI (an infliximab biosimilar referencing REMICADE). Further extending its therapeutic reach, Biogen supplies RITUXAN, prescribed for conditions like non-Hodgkin's lymphoma, chronic lymphocytic leukemia (CLL), rheumatoid arthritis, certain types of ANCA-associated vasculitis, and pemphigus vulgaris.
