About LUPKYNIS

LUPKYNIS is the first FDA-approved oral therapy for lupus nephritis (LN). LN causes irreversible kidney damage and significantly increases the risk of kidney failure, cardiac events, and death. It is one of the most serious and common complications of the autoimmune disease systemic lupus erythematosus (SLE). LUPKYNIS is in the United States (U.S.) and across the European Union (E.U).

About Lupus Nephritis

LN is a serious manifestation of SLE, a chronic and complex autoimmune disease. About 200,000-300,000 people live with SLE in the U.S. and about one-third of these people are diagnosed with lupus nephritis at the time of their SLE diagnosis. About 50 percent of all people with SLE may develop lupus nephritis. If poorly controlled, LN can lead to permanent and irreversible tissue damage within the kidney. Black and Asian individuals with SLE are four times more likely to develop LN and individuals of Hispanic ancestry are approximately twice as likely to develop the disease when compared with Caucasian individuals. Black and Hispanic individuals with SLE also tend to develop LN earlier and have poorer outcomes when compared to Caucasian individuals.
