Amgen Inc. on Monday said the U.S. Food and Drug Administration approved the expanded use of its Riabni biosimilar to Rituxan in certain patients with the chronic inflammatory joint disease rheumatoid arthritis.

Amgen said the approval covers Riabni in combination with methotrexate for adults with moderate to severely active rheumatoid arthritis who have had an inadequate response to one or more tumor necrosis factor antagonist therapies.

Biosimilars are near-copies of biologic drugs, such as Rituxan, that are made from living cells and are analogous to generic copies of traditional medicines.

Rituxan is jointly marketed by Biogen Inc. and Roche Holding AG's Genentech unit.

The FDA previously approved Riabni for the treatment of adults with non-Hodgkin's lymphoma, chronic lymphocytic leukemia, granulomatosis with polyangiitis (also called Wegener's granulomatosis) and microscopic polyangiitis.
