Preliminary Fourth Quarter 2022 LUPKYNIS Product Metrics

• There were approximately 1,525 patients on LUPKYNIS therapy at December 31, 2022, compared with 1,354 at September 30, 2022.
• Aurinia added approximately 406 patient start forms (PSFs) during the fourth quarter 2022, as compared to 374 in the third quarter 2022.

“Given strong commercial execution in the fourth quarter, we demonstrated substantial growth in our key metrics for LUPKYNIS, including an increased total number of patients on therapy and an uptick in patient start forms in the back half of the fourth quarter, compared to the monthly average in the third quarter of 2022,” said Peter Greenleaf, President and Chief Executive Officer of Aurinia. “Given this progress, we believe we have achieved our 2022 full year net product revenue guidance and are positioned to achieve our net revenue guidance from product sales for 2023 in the range of $120-$140 million.”

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 approved in the United States (U.S.), the United Kingdom 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.
