“As previously reported on our fourth quarter call, LUPKYNIS revenues in the first quarter were impacted by care disruptions to both patients and the healthcare system caused by the COVID-19 Omicron variant. We are quite pleased that exiting the quarter, as Omicron abated, we began to see a significant increase in prescribing, patient starts, and refills, leading to a monthly record for received patient start forms and patient starts in March,” said Peter Greenleaf, President and Chief Executive Officer of Aurinia. “Heading into the second half of the year, in addition to expected growth in LUPKYNIS revenues, we look forward to multiple expected corporate milestones, including potential European LUPKYNIS approval, the presentation of additional clinical data sets and continued development progress with our pipeline products, AUR200 and AUR300.”

For fiscal year 2022, the Company maintains its net revenue guidance of $115 million to $135 million from sales of LUPKYNIS. This range is based on assumptions regarding the impact of COVID-19 on the current business environment and represents an increase of more than 150 to 200% in net revenue from sales of LUPKYNIS compared to fiscal year 2021. Aurinia’s guidance does not include any potential milestone payments, royalties or contract manufacturing revenue related to the Company’s licensing agreement with Otsuka Pharmaceutical or associated with the marketing of voclosporin in the European Union or Japan.

•The first presentations of final AURORA 2 continuation study data are expected at the 59th European Renal Association (ERA) Congress and at the European Congress of Rheumatology at the end of May 2022 and at the European Alliance of Associations for Rheumatology (EULAR) 2022 in June. Submission of a manuscript with the full results is expected in the second half of 2022.

As of March 31, 2022, Aurinia had cash, cash equivalents and restricted cash and investments of $418.8 million compared to $466.1 million at December 31, 2021. The decrease in cash, cash equivalents and restricted cash and investments is primarily related to the continued investment in commercialization activities, payments made for our ongoing post approval obligations and advancement of our pipeline, payments associated with inventory purchases to ensure adequate supply to meet forecasted demand and a payment for the achievement of a one-time milestone, partially offset by an increase in cash receipts from sales of LUPKYNIS.

Aurinia believes that it has sufficient financial resources to fund its current operations, which include funding commercial activities, including FDA related post approval commitments, manufacturing and packaging of commercial drug supply, funding its supporting commercial infrastructure, conducting planned research and development (R&D) programs, investing in its pipeline and operating activities for at least the next few years.

Total net revenue was $21.6 million and $914 thousand for the quarters ended March 31, 2022 and March 31, 2021, respectively. Net revenues primarily consisted of product revenue, net of adjustments for LUPKYNIS, following FDA approval in late January 2021. Quarter over quarter revenue growth is attributed to continued progress in the launch of LUPKYNIS, driven predominantly by further penetration into the LN market.

Selling, general and administrative (SG&A) expenses were $45.2 million and $39.8 million for the quarters ended March 31, 2022 and March 31, 2021, respectively, which is consistent with the prior quarter and represents a fully burdened quarter, as the Company did not have approval until late January 2021. The increase was primarily due to an increase in employee related expenses, professional fees related to various corporate matters, pharmacovigilance costs and consulting related expenses tied to the increased investment in back office infrastructure to support the commercialization of LUPKYNIS.

R&D expenses were $12.6 million and $9.8 million for the quarters ended March 31, 2022 and March 31, 2021, respectively. The primary driver for the increase quarter over quarter was due to an increase in expenses related to AUR200 and AUR300 development, partially offset by a decrease in expenses related to the AURORA 2 continuation study which was completed during the fourth quarter of 2021 but had wind down activities ongoing in the quarter ended March 31, 2022.

LN is a serious progression of systemic lupus erythematosus (SLE), a chronic and complex autoimmune disease. About 200,000-300,000 people live with SLE in the U.S. and approximately one out of three of these individuals have already developed LN at the time of SLE diagnosis. If poorly controlled, LN can lead to permanent and irreversible tissue damage within the kidney, resulting in kidney failure. Black and Asian individuals with SLE are four times more likely to develop LN and individuals with 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.

Aurinia Pharmaceuticals is a fully integrated biopharmaceutical company focused on delivering therapies to treat targeted patient populations that are impacted by serious diseases with a high unmet medical need. In January 2021, the Company has introduced LUPKYNIS (voclosporin), the first FDA-approved oral therapy dedicated for the treatment of adult patients with active LN. The Company’s head office is in Victoria, British Columbia, its U.S. commercial office is in Rockville, Maryland. The Company focuses its development efforts globally.
