Aurinia Pharmaceuticals Announces Collaboration Partner Otsuka Filed New Drug Application (NDA) for LUPKYNIS (Voclosporin) in Japan

Aurinia Pharmaceuticals Inc. (NASDAQ: AUPH) (Aurinia or the Company) today announced that the Company’s collaboration partner, Otsuka Pharmaceutical Ltd., filed a new drug application (NDA) for voclosporin for the treatment of lupus nephritis (LN) with the Japanese Ministry of Health, Labour, and Welfare for the manufacture and sale in Japan of voclosporin, a second-generation oral calcineurin inhibitor for the treatment of lupus nephritis (LN). LN is a complication of the autoimmune disease systemic lupus erythematosus (SLE) that seriously impacts the kidneys. In January 2021, the U.S. Food and Drug Administration (FDA) approved voclosporin in combination with a background immunosuppressive therapy regimen for the treatment of adult patients with active LN and it is currently available in the U.S. under the brand name LUPKYNIS.

Aurinia and Otsuka entered a collaboration and licensing agreement in December 2020 for the development and commercialization of voclosporin for the treatment of LN in the EU, Japan, the United Kingdom, Russia, Switzerland, Norway, Belarus, Iceland, Liechtenstein, and Ukraine. As part of the agreement, Aurinia is eligible to receive a payment of $10 million upon approval in Japan along with low double-digit royalties on net sales once launched.

“Lupus nephritis is a serious, complex condition associated with SLE, that can benefit from advanced therapies that focus toward the treatment goal of kidney preservation,” said Peter Greenleaf, President, and Chief Executive Officer of Aurinia Pharmaceuticals. “We look forward to continuing to work with Otsuka to expand availability to voclosporin and provide patients and physicians access to this new therapy that addresses a significant unmet need in lupus nephritis.”

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.
