WASHINGTON--(BUSINESS WIRE)--The Lupus Foundation of America today praised the results of a new long-term study for the treatment of lupus nephritis (lupus-related kidney disease) which demonstrated superiority of CellCept® (mycophenolate mofetil or MMF) to azathioprine (standard care) as a long-term treatment for lupus nephritis. The Phase III study results released by Vifor Pharma and Roche convincingly reached the primary endpoint of delaying treatment failure in patients with lupus nephritis who had successfully responded to induction therapy and were in remission.
