Voclosporin for Lupus Nephritis: Assessment of Long-Term Safety and Efficacy Including Renal Outcome Over 3 Years of Treatment in the Phase 3 AURORA 1 and AURORA 2 Studies
Bibliographic record
Abstract
Background: In AURORA 1, adding voclosporin to mycophenolate mofetil (MMF) and low-dose steroids led to significant reductions in proteinuria at 1 year in patients with lupus nephritis (LN). We report on the recently completed AURORA 2 study evaluating voclosporin compared to placebo in patients treated for an additional 2 years after AURORA 1. Methods: Patients with LN completing AURORA 1 were eligible to continue on the same double-blinded treatment of voclosporin or placebo in AURORA 2; all patients recieved MMF and low-dose steroids. Outcomes assessed over the 3 year treatment period of both studies included adverse events (AEs), eGFR, urine protein-creatinine ratio (UPCR), good renal outcome and renal flare. Good renal outcome was defined based on achievement of an adequate response (i.e. sustained reduction in UPCR to ≤0.7 mg/mg) and without renal flare (i.e. an increase to UPCR >1 mg/mg from a post-response UPCR of <0.2 mg/mg or an increase to UPCR >2 mg/mg from a post-response UPCR of 0.2 to 1.0 mg/mg), as adjudicated by a blinded Clinical Endpoints Committee. Results: Overall rates of serious AEs in the voclosporin (26.7% of 116 patients) and control arm (28.0% of 100 patients) were similar. There were no deaths in the voclosporin arm during AURORA 2; four deaths occured in the control arm (pulmonary embolism, n=1; coronavirus infection, n=3). Mean corrected eGFR was within the normal range and stable over the study period. The reductions in UPCR achieved in AURORA 1 were maintained in AURORA 2 and significantly more patients in the voclosporin arm achieved a good renal outcome (66.4% in voclosporin vs 54.0% in control; p-value=0.045). Renal flare occurred in 24 of 101 patients with adequate response in the voclosporin arm and 19 of 73 patients in the control arm (23.8% in voclosporin vs 26.0% in control; p-value=0.662); 69.8% of all patients with renal flares completed study treatment. Conclusions: Voclosporin was well-tolerated over three years of treatment. The significant reductions in proteinuria initially achieved in AURORA 1 were maintained throughout AURORA 2 and more patients in the voclosporin arm achieved a good renal outcome. These data provide evidence of a long-term treatment benefit of voclosporin in patients with lupus nephritis. Funding: Commercial Support - Aurinia Pharmaceuticals Inc.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
