Aurinia Presents Additional AURORA Pivotal Trial Safety Data at the ERA-EDTA Virtual Congress 2020

VICTORIA, British Columbia--(BUSINESS WIRE)--June 9, 2020--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 additional safety data from the completed AURORA pivotal trial of voclosporin were shared at the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) 2020 Virtual Congress in an oral presentation given by nephrologist Dawn Caster, M.D., Assistant Professor of Medicine at the University of Louisville School of Medicine.

The data showed that pre-specified confirmed estimated glomerular filtration rate (eGFR) decreases of over 30% were similar in both AURORA trial patient groups, with 10.1% reported in the voclosporin group and 10.2% in the control arm (p=0.971). eGFR is a standard measure of kidney function. No clinically meaningful differences between the treatment (23.7 mg twice daily oral voclosporin) and control groups were seen at any timepoints in the study on this parameter or in serum creatinine levels, another biomarker for renal damage. All patients in the AURORA study were treated with mycophenolate (MMF) and a background of corticosteroids. MMF is considered the standard-of-care for lupus nephritis, although unapproved by the FDA for that use.

“This important new aspect of the full AURORA results further adds to the existing dataset that shows voclosporin’s benefit over the standard-of-care with no apparent safety penalty,” said Neil Solomons, M.D., Chief Medical Officer of Aurinia. “Our deep analysis of the comprehensive voclosporin clinical program continues to illustrate its potential as a treatment for lupus nephritis. This data has been submitted to the FDA as part of voclosporin’s recently completed New Drug Application.”

As previously reported, AURORA met its primary endpoint, achieving statistically superior Renal Response rates of 40.8% for voclosporin versus 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 versus 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 eGFR or increase in blood pressure, lipids or glucose, which are common adverse events associated with legacy calcineurin inhibitors (CNIs).

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. The Company’s head office is in Victoria, British Columbia, its U.S. commercial hub in Rockville, Maryland, and focuses its development efforts globally.
