Aurinia Presents AURORA Pivotal Trial Subgroup Analysis at the EULAR 2020 E-Congress

All pre-specified subgroup analyses in the pivotal trial favored voclosporin over placebo

VICTORIA, British Columbia--(BUSINESS WIRE)-- Aurinia Pharmaceuticals Inc. (Nasdaq:AUPH / TSX:AUP) (“Aurinia” or the “Company”), a late-stage clinical biopharmaceutical company focused on advancing voclosporin across multiple indications, announced that new subgroup analyses from the completed AURORA pivotal trial of voclosporin were presented. The data were shared today at the European League Against Rheumatism (EULAR) 2020 E-Congress in an oral presentation given by Cristina Arriens, M.D., M.S.C.S., Clinical Assistant Member of the Arthritis and Clinical Immunology Research Program at the Oklahoma Medical Research Foundation (OMRF).

The presented data demonstrated clinically meaningful benefits of voclosporin for trial participants across ethnicities and self-reported race. Significant renal response rates were seen for Hispanic/Latino (p=0.0062, OR 3.45) patients in the voclosporin arm (38.6%) versus control arm (18.6%), as well as for non-Hispanic/Latino patients (p=0.0045, OR 2.29) in the voclosporin arm (41.8%) versus the control arm (24.6%). Furthermore, all other pre-specified subgroup analyses (age, sex, race, biopsy class, region, and prior mycophenolate mofetil use) favored voclosporin.

“The robustness of renal response across race and ethnicity and the onset of voclosporin effect have the potential to change the natural course of this debilitating disease,” stated Neil Solomons, M.D., Chief Medical Officer of Aurinia. “The treatment benefits observed across all clinically important subgroups further strengthens our confidence in voclosporin as a potential treatment for people living with lupus nephritis.”

As previously reported, AURORA met its primary endpoint, achieving statistically superior Renal Response rates of 40.8% for voclosporin vs. 22.5% for the control (OR 2.65, 95% CI; p < 0.001). The benefits of voclosporin were also seen for all prespecified hierarchical secondary endpoints, achieving statistical significance in favor of voclosporin for Renal Response at 24 weeks, Partial Renal Response at 24 and 52 weeks, time to achieve urinary protein-to-creatinine ratio (UCPR) ≤ 0.5, and time to 50% reduction in UPCR.

Voclosporin was well tolerated with no unexpected safety signals. Serious adverse events (SAEs) were reported in 20.8% of voclosporin patients vs. 21.3% in the control arm. Infection was the most commonly reported SAE with 10.1% of voclosporin patients versus 11.2% of patients in the control arm. Overall mortality in the trial was low, with six deaths observed; one in the voclosporin arm and five in the control group. Additionally, the voclosporin arm showed no significant decrease at week 52 in estimated glomerular filtration rate (eGFR) or increase in blood pressure, lipids or glucose, which are common adverse events associated with legacy calcineurin inhibitors (CNIs).

The data presented at EULAR 2020 was submitted as part of voclosporin’s new drug application (NDA) to the United States Food and Drug Administration (FDA) which was completed on May 25, 2020.

About Voclosporin

Voclosporin, an investigational drug, is a novel and potentially best-in-class calcineurin inhibitor (CNI) with clinical data in over 2,600 patients across indications. Voclosporin is an immunosuppressant, with a synergistic and dual mechanism of action. By inhibiting calcineurin, voclosporin blocks IL-2 expression and T-cell mediated immune responses and stabilizes the podocyte in the kidney. It has been shown to have a more predictable pharmacokinetic and pharmacodynamic relationship (potentially requires no therapeutic drug monitoring), an increase in potency (versus cyclosporine A), and an improved metabolic profile compared to legacy CNIs. Aurinia anticipates that upon regulatory approval, patent protection for voclosporin will be extended in the United States and certain other major markets, including Europe and Japan, until at least October 2027 under the Hatch-Waxman Act and comparable laws in other countries and until April 2028 with anticipated pediatric extension. Further, a U.S. patent has also been issued covering the voclosporin dosing protocol with a term extending to December 2037, if the FDA incorporates the dosing protocol used in both the AURA and AURORA trials into the product label.

About Lupus Nephritis

Lupus nephritis (LN) is an inflammation of the kidney caused by Systemic Lupus Erythematosus (SLE) and represents a serious progression of SLE. SLE is a chronic, complex and often disabling disorder. The disease is highly heterogeneous, affecting a wide range of organs and tissue systems. Unlike SLE, LN has straightforward disease outcomes, where an early reduction in proteinuria correlates with positive long-term outcomes. In patients with LN, renal damage results in proteinuria and/or hematuria and a decrease in renal function as evidenced by reduced eGFR, and increased serum creatinine levels. LN is debilitating and costly and if poorly controlled, LN can lead to permanent and irreversible tissue damage within the kidney, resulting in end-stage renal disease (ESRD), thus making LN a serious and potentially life-threatening condition.

About Aurinia

Aurinia Pharmaceuticals is a late-stage clinical biopharmaceutical company focused on developing and commercializing therapies to treat targeted patient populations that are impacted by serious diseases with a high unmet medical need. The Company is currently developing the investigational drug voclosporin for the treatment of lupus nephritis, other proteinuric diseases and dry eye syndrome.
