Aurinia Pharmaceuticals Inc. (Nasdaq:AUPH / TSX:AUP) (“Aurinia” or the “Company”), a late-stage clinical biopharmaceutical company focused on advancing voclosporin across multiple indications, today announced that integrated efficacy and pharmacokinetic (PK) data from Aurinia’s AURA-LV and AURORA pivotal trials of voclosporin in lupus nephritis (LN) were presented. The data were shared at the American Society of Nephrology (ASN) Kidney Week 2020 in presentations given by Brad Rovin, M.D., FASN, Director of Nephrology and Vice Chairman of Research for the Department of Internal Medicine at the Ohio State University Wexner Medical Center and Teun van Gelder, Professor in Clinical Pharmacology for the Department of Clinical Pharmacy and Toxicology at the Leiden University Medical Center.

“People living with lupus nephritis are in a race against time to get their disease under control with the goal of improving their long term kidney health. We are pleased that the pooled analysis from our AURA-LV and AURORA pivotal trials further underscores voclosporin’s potential as an important tool to help people quickly change the course of their disease,” said Neil Solomons, M.D., Chief Medical Officer of Aurinia. “Together with the supportive pharmacokinetic data, these findings add to the growing body of information available on voclosporin as an investigational drug that could provide an important treatment approach for people dealing with LN.”

Data from a total of 534 patients from AURA-LV and AURORA was integrated and presented, demonstrating that 268 patients with LN treated with voclosporin in combination with mycophenolate mofetil (MMF) and low-dose steroids achieved statistically superior and faster Renal Response rates compared to 266 patients treated with MMF and steroids alone. The effects were also observed in Hispanic patients, a high-risk lupus nephritis population. Treatment with voclosporin resulted in clinically meaningful and a statistically significant higher Renal Response rate of 43.7% compared to 23.3% in the control arm at one year (OR 2.76, 95% CI: 1.88, 4.05; p

The Company also presented PK data analyzed from the AURA-LV and AURORA studies further supporting the potential to eliminate the need for therapeutic drug monitoring. The influence of various covariates on voclosporin’s PK was evaluated based on a population PK model and calcineurin inhibition was estimated using concentration data in the LN population and previously measured inhibition. At the recommended therapeutic dose of 23.7 mg twice daily, sex, body weight, race, age, serum albumin, total bilirubin and estimated glomerular filtration rate (eGFR) demonstrated no clinically relevant effect on voclosporin’s PK parameters. Voclosporin was shown to inhibit calcineurin in a dose-dependent manner. In a quartile exposure analysis, no relationship with the odds ratio for renal response was observed and favored voclosporin in all quartiles. The linear PK profile of voclosporin allows the use of a pharmacodynamic approach instead of a pharmacokinetic approach, in which the dose of voclosporin is adjusted in response to decreases in eGFR.

The AURA-LV and AURORA studies were of similar design and conducted in comparable patient populations. The data from both studies for subjects treated with the recommended voclosporin dose of 23.7 mg twice daily (AURORA; n=179, AURA-LV; n=89) or with matching placebo (AURORA; n= 178, AURA-LV; n=88) were therefore pooled for an integrated analysis.

The data presented at ASN Kidney Week 2020 was submitted as part of voclosporin’s new drug application (NDA) to the United States Food and Drug Administration (FDA). The FDA accepted the NDA, agreed to Priority Review, and has assigned a Prescription Drug User Fee Act (PDUFA) target action data of January 22, 2021.

These forward-looking statements or information include but are not limited to statements or information with respect to: the Company’s belief that the voclosporin efficacy and PK data from the integrated analysis of the AURA-LV and AURORA studies supports consistent dose-response, has the potential to eliminate the need for therapeutic drug monitoring, underscores voclosporin as a potentially important tool to help people quickly change the course of their disease, and could provide an important treatment approach for people dealing with LN; the Company’s PDUFA target action data of January 22, 2021; and the potential FDA approval of voclosporin as a potential treatment for LN. It is possible that such results or conclusions may change based on further analyses of these data. Words such as “anticipate”, “will”, “believe”, “estimate”, “expect”, “intend”, “target”, “plan”, “goals”, “objectives”, “may” and other similar words and expressions, identify forward-looking statements.
