Aurinia Pharmaceuticals Inc. (NASDAQ: AUPH) (“Aurinia” or the “Company”) today received notice regarding the U.S. Patent Office (USPTO) Patent Trial and Appeal Board (PTAB) decision to institute trial on the Inter Partes review (“IPR”) filed by Sun Pharmaceuticals, directed at U.S. Patent No. 10,286,036. This patent is related to the LUPKYNIS^® dosing protocol for lupus nephritis.

“While this decision is disappointing, as we have stated from the start of his process, we will vigorously defend this patent,” said Peter Greenleaf, President and CEO, Aurinia Pharmaceuticals. “This patent already had significant review at the USPTO before being approved as being a valid patent by that office and we are fully prepared to continue legal proceedings to protect our intellectual property.”

Patent No. 10,286,036 was issued to Aurinia in support of the unique eGFR pharmacodynamic dosing protocol used within the Company’s clinical trials, and extends patent protection for LUPKYNIS to 2037. Regardless of the final outcomes of the IPR, the Company has filed a standard form patent term extension for its existing composition of matter patent, which, if granted, would extend the term of that patent by 5 years to October 2027. A determination on patentability, relative to the IPR, is expected on or prior to July 26, 2023.
