ROCKVILLE, Md. & EDMONTON, Alberta, May 22, 2025--(BUSINESS WIRE)--Aurinia Pharmaceuticals Inc. (NASDAQ: AUPH) (Aurinia or the Company), today announced that a post-hoc analysis of the 52-week, Phase 3 AURORA 1 study showed that lupus nephritis (LN) patients who received triple immunosuppressive therapy with LUPKYNIS® (voclosporin), mycophenolate mofetil (MMF), and low-dose glucocorticoids achieved lower proteinuria targets at substantially higher rates compared to patients in the control group who received mycophenolate mofetil (MMF) and low-dose glucocorticoids alone.

The analysis assessed the achievement of urine protein creatine ratio (UPCR) targets of ≤0.4 g/g, ≤0.3 g/g, ≤0.2 g/g (classified as ultra-low UPCR), and ≤0.1 g/g in LN patients treated with LUPKYNIS-based triple immunosuppressive therapy compared to patients in the control group. Of the 357 patients in AURORA 1, 60.9% in the triple immunosuppressive therapy group (N=109) achieved a UPCR of ≤0.4 g/g at least once during the study compared to 37.1% of patients in the control group (N=66). Patients in the triple immunosuppressive therapy group also achieved higher rates of all other UPCR targets compared to patients in the control group. Adverse event rates were comparable in both groups.

"It is widely known that no level of proteinuria is safe for nephrons and that early reductions in proteinuria are predictive of better long-term kidney outcomes. Yet, UPCR endpoints have varied widely across clinical trials and in clinical practice," said lead study author Maria Dall’Era, M.D., Professor of Medicine in the Division of Rheumatology, University of California, San Francisco. "This analysis shows that achieving UPCR targets of ≤0.4 g/g may be a feasible goal and that a voclosporin-based triple immunosuppressive therapy regimen can reduce proteinuria to profoundly low levels in a proportion of patients."

An additional post-hoc analysis from the AURORA 1 study evaluated lipidomic profiles in LN patients based on achievement of proteinuria reductions, including ultra-low UPCR, at Week 52. The analysis found a distinct lipidomic profile in patients who achieved ultra-low UPCR. This analysis builds upon a previous analysis of AURORA 1 in which patients who received triple immunosuppressive therapy with LUPKYNIS achieved significantly greater improvements in total and low-density lipoprotein (LDL) cholesterol compared to those in the control group. While further research is needed to clarify the role of certain lipids in the biochemistry of LN patients, these preliminary findings suggest that attaining ultra-low UPCR targets may provide additional benefits to LN patients and contribute to modification of cardiovascular disease risk.
