An evaluation of voclosporin for the treatment of lupus nephritis.

Lupus nephritis (LN) is associated with significant morbidity and mortality. Current treatment outcomes remain suboptimal. No disease modifying medications are licensed for the treatment of LN. Voclosporin, a novel calcineurin inhibitor, has been investigated as induction therapy in LN in combination with myocophenolate mofetil (MMF) and a glucocorticoid (GC). Two phase II trials of voclosporin were the first trials of a potential treatment of active LN that met their primary endpoints. Areas covered: This article reviews the pharmacology of voclosporin and the efficacy and safety data from the two existing phase II trials. In the phase IIb randomized controlled trial AURA-LV, voclosporin was shown to be superior to placebo, when used in combination with MMF (1-2 g/day) and GC, in achieving remission in active LN. Expert opinion: While the positive outcome of existing trials is promising, further data confirming its efficacy and evaluating its safety are required. A phase III trial is currently recruiting. Importantly, the positive results were achieved despite a novel and rapid GC taper regime, suggesting that rapid taper of GC may be a viable treatment option in active LN which merits further investigation.
