Aurinia Completes Enrollment of AURORA, its Phase 3 Clinical Trial for the Treatment of Lupus Nephritis

Aurinia Pharmaceuticals Inc. (NASDAQ: AUPH/TSX:AUP), a clinical stage biopharmaceutical company focused on the global immunology market, today announced that it has completed enrollment for the AURORA Phase 3 trial ahead of schedule. The target enrollment of 324 patients was surpassed due to high patient demand with 358 lupus nephritis (LN) patients randomized in sites across 27 countries.

“We are elated by the significant interest this trial has garnered around the globe, which reinforces the need for new treatment options for patients living with lupus nephritis,” said Richard M. Glickman, Aurinia’s Chairman and Chief Executive Officer. “I continue to be impressed by the level of dedication exhibited by our team to execute this trial with great diligence and expediency.”

The AURORA clinical trial is a global, double-blind, placebo-controlled study to evaluate whether voclosporin when added to background therapy of mycophenolate mofetil (MMF)/CellCept® can increase speed of and overall renal response rates in the presence of low dose steroids. The primary endpoint for the study is complete renal response at 52 weeks, after which patients can choose to enroll into a 104-week blinded extension study.

“We would like to thank our trial patients, physicians, trial site staff, and advocacy groups for their extraordinary efforts which has led to this result,” said Neil Solomons, M.D., Aurinia’s Chief Medical Officer. “We look forward to sharing the results of the trial in late Q4 2019 and to completing our NDA submission in Q2 2020.”

About Voclosporin

Voclosporin, an investigational drug, is a novel and potentially best-in-class CNI with clinical data in over 2,400 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 (requires no therapeutic drug monitoring), an increase in potency (vs cyclosporin), 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.

About Lupus Nephritis (LN)

LN in 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 & tissue systems. Unlike SLE, LN has straightforward disease outcomes (measuring proteinuria) where an early response correlates with 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 estimated glomerular filtration rate (“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.
