Abstract: OBJECTIVE: This integrated analysis evaluates the efficacy and safety of voclosporin, a novel calcineurin inhibitor, at 23.7 mg twice daily in combination with mycophenolate mofetil (MMF) and oral glucocorticoids in lupus nephritis (LN) using pooled data from two large phase II and phase III clinical trials. The purpose was to expand the pool of patients for safety analyses and to increase power for efficacy analyses in patient subpopulations. METHODS: Aurinia Urinary Protein Reduction in Active Lupus with Voclosporin (AURA-LV) (phase II) and Aurinia Renal Response in Active Lupus With Voclosporin (AURORA 1) (phase III) were randomized, placebo-controlled, double-blind trials with similar designs and end points comparing voclosporin to control in combination with MMF and oral glucocorticoids for the treatment of LN. The primary efficacy outcome of the integrated analysis was complete renal response (CRR) at approximately one year (Week 48 data from AURA-LV and Week 52 from AURORA 1). Safety was assessed throughout the trials. RESULTS: Overall, 534 patients (268 voclosporin; 266 control) were included in the integrated analysis. Significantly more patients achieved a CRR at one year in the voclosporin group than in the control group (43.7% vs. 23.3%; OR 2.76; 95% CI 1.88, 4.05 P < 0.0001). The incidence of adverse events (AEs) was similar (91.4% voclosporin; 87.2% control). Most AEs were mild to moderate in severity; the most commonly reported AEs were classified as infections and infestations (62.2% voclosporin; 54.9% control) and gastrointestinal disorders (45.3% voclosporin; 35.3% placebo). No new or unexpected safety signals were detected. CONCLUSIONS: This integrated analysis demonstrates the efficacy and safety of voclosporin in the treatment of LN across the diverse racial and ethnic groups studied.

The second-generation CNI voclosporin causes hypomagnesaemia and hypercalciuria less often than tacrolimus. This suggests different effects on the distal tubule, but this has not yet been investigated experimentally. METHODS: Rats were treated with voclosporin, tacrolimus or vehicle for 28 days. Dosing was based on a pilot experiment to achieve clinically therapeutic concentrations. Drug effects were assessed by electrolyte handling at day 18 and 28, thiazide testing at day 20, telemetric BP recordings and analysis of messenger RNA (mRNA) and protein levels of distal tubular transporters at day 28. RESULTS: Compared with vehicle, tacrolimus but not voclosporin significantly increased the fractional excretions of calcium (>4-fold), magnesium and chloride (both 1.5-fold) and caused hypomagnesaemia. Tacrolimus but not voclosporin significantly reduced distal tubular transporters at the mRNA and/or protein level, including the sodium-chloride cotransporter, transient receptor melastatin 6, transient receptor potential vanilloid 5, cyclin M2, sodium-calcium exchanger and calbindin-D28K. Tacrolimus but not voclosporin reduced the mRNA level and urinary excretion of epidermal growth factor. The saluretic response to hydrochlorothiazide at day 20 was similar in the voclosporin and vehicle groups, whereas it was lower in the tacrolimus group. The phosphorylated form of the sodium-chloride cotransporter was significantly higher at day 28 in rats treated with voclosporin than in those treated with tacrolimus. Tacrolimus transiently increased BP, whereas voclosporin caused a gradual but persistent increase in BP that was further characterized by high renin, normal aldosterone and low endothelin-1. CONCLUSIONS: In contrast to tacrolimus, voclosporin does not cause hypercalciuria and hypomagnesaemia, but similarly causes hypertension. Our data reveal differences between the distal tubular effects of tacrolimus and voclosporin and provide a pathophysiological basis for the clinically observed differences between the two CNIs.Linked Compounds Count: 30

One of the main treatment goals for LN is preservation of kidney function, with early decreases in proteinuria associated with improved long-term outcomes. Voclosporin, a second-generation calcineurin inhibitor, was approved in the United States in 2021 for the treatment of active LN combined with background immunosuppression. The AURORA 1 study found that the use of voclosporin with low doses of mycophenolate mofetil and glucocorticoids yielded significant reductions in proteinuria. The AURORA 2 study showed long-term efficacy and safety of voclosporin over a 3-year period with kidney function preservation. The Institute for Clinical and Economic Review (ICER) is a nonprofit organization that evaluates medical evidence to help improve patient outcomes and control costs. In 2021, ICER published an economic model to estimate the impact and cost-effectiveness of LN therapies. From a US health care perspective, voclosporin was cost-effective at $149,260 per quality-adjusted life-year (QALY) and $131,528 per equal value of life-years gained (evLYG). At the time of the LN cost-effectiveness model (CEM) development, voclosporin was not yet approved in the United States and the cost of treating patients with LN with ESKD was not captured in the literature. OBJECTIVE: To evaluate the cost-effectiveness of voclosporin given the emergence of new data. METHODS: The LN CEM uses a short-term trial-based Markov model and long-term extrapolation using partitioned survival modeling data assuming adults with LN start with active disease, transitioning to complete or partial renal response, kidney failure, or death. In the current analysis, clinical data for voclosporin, duration of voclosporin treatment for nonresponders, and drug costs reflecting the 2023 price of voclosporin were updated. Additionally, health care payer costs of disease management were incorporated based on real-world claims data on the costs of treating patients with LN. RESULTS: Using the LN CEM with inputs reflecting the latest and most relevant evidence, the incremental cost of voclosporin per QALY was $88,076 and per evLYG was $77,643. For a subpopulation of Black, Hispanic, and Latino patients, the incremental cost of voclosporin per QALY was $77,435 and per evLYG was $67,828. CONCLUSIONS: Following the inclusion of updated data in the cost-effectiveness analysis, voclosporin remains a cost-effective therapy for the treatment of active LN including in a Black, Hispanic, and Latino subpopulation, substantially below the ICER willingness-to-pay threshold of $150,000/QALY.Linked Compounds Count: 19

METHODS: EAU was induced by immunization with a uveitogenic protein. Voclosporin administration, by subcutaneous injection, began on day (d) 0 or d7 after immunization. Treatment effectiveness was evaluated in vivo using clinical EAU scoring (d7-d13) and histopathologic evaluation of enucleated eyes after experimental termination. Rodent lymphocytes were harvested from lymph nodes on d14 for antigen-specific proliferation assays. The effect of voclosporin on human T-cell proliferation and cytokine secretion was examined in vitro. RESULTS: Voclosporin prevented EAU development in rats receiving medium and high preventive doses, whereas high-dose voclosporin administration effectively treated EAU. Lymphocytes from animals treated with voclosporin had decreased antigen-specific proliferation in vitro compared with lymphocytes from untreated animals. No evidence of abnormal ocular histopathology was found in the eyes from animals that received high doses of therapeutic voclosporin. Using human T cells, voclosporin inhibited human T-cell proliferation up to 100-fold. Furthermore, voclosporin treatment of human T cells significantly reduced pan T-cell effector responses. CONCLUSIONS: Voclosporin effectively suppressed uveoretinitis in an animal model that imitates the human inflammatory ocular disease by inhibiting lymphocyte proliferation. In addition, voclosporin effectively inhibited human T-cell proliferation and function in vitro. The authors report the first evidence supporting the application of voclosporin to treat intraocular inflammation.Linked Compounds Count: 19

The AURA-LV study tested the novel calcineurin inhibitor voclosporin for efficacy and safety in active LN. AURA-LV was a Phase 2, multicenter, randomized, double-blind, placebo-controlled trial of two doses of voclosporin (23.7 mg or 39.5 mg, each twice daily) versus placebo in combination with mycophenolate mofetil (2 g/d) and rapidly tapered low-dose oral corticosteroids for induction of remission in LN. The primary endpoint was CRR at 24 weeks; the secondary endpoint was CRR at 48 weeks. Two hundred sixty-five subjects from 79 centers in 20 countries were recruited and randomized to treatment for 48 weeks. CRR at week 24 was achieved by 29 (32.6%) subjects in the low-dose voclosporin group, 24 (27.3%) subjects in the high-dose voclosporin group, and 17 (19.3%) subjects in the placebo group (OR=2.03 for low-dose voclosporin versus placebo). The significantly greater CRR rate in the low-dose voclosporin group persisted at 48 weeks, and CRRs were also significantly more common in the high-dose voclosporin group compared to placebo at 48 weeks. There were more serious adverse events in both voclosporin groups, and more deaths in the low-dose group compared to placebo and high-dose voclosporin groups (11.2%, 1.1%, and 2.3%, respectively). These results suggest that the addition of low-dose voclosporin to mycophenolate mofetil and corticosteroids for induction therapy of active LN results in a superior renal response compared to mycophenolate mofetil and corticosteroids alone, but higher rates of adverse events including death were observed.Linked Compounds Count: 23

We hypothesised that the addition of voclosporin to low-dose GCs and mycophenolate mofetil (MMF) would reduce exposure to the toxicities of high-dose GC-based dual immunosuppressive therapy regimens, resulting in an improved safety profile without compromising efficacy. METHODS: Propensity score matching generated two groups of matched participants from the voclosporin arms (in combination with MMF (2 g/day) and low-dose GCs) of the Phase 2 AURA-LV and Phase 3 AURORA 1 studies and the MMF (3 g/day) and intravenous cyclophosphamide (IVC) arms (both in combination with high-dose GCs) of the Aspreva Lupus Management Study (ALMS) induction study. Safety and efficacy outcomes were assessed over 6 months. RESULTS: There were 179 matched participants identified between the AURA-LV/AURORA 1 studies and ALMS. The overall incidence of adverse events (AEs) was higher in IVC- and MMF-treated participants of ALMS; more voclosporin-treated participants reported AEs by preferred term of glomerular filtration rate decreased, hypertension and anaemia. The incidence of serious AEs was similar across treatments. There were four (2.2%) deaths in IVC- and MMF-treated participants of ALMS compared with seven (3.9%) deaths in voclosporin-treated participants. Significantly more voclosporin-treated participants achieved a ≥25% reduction in urine protein creatinine ratio (UPCR) from baseline at 3 months and ≥50% reduction in UPCR from baseline at 6 months. CONCLUSIONS: Compared with the high-dose GC-based regimens used in ALMS, voclosporin-based triple immunosuppressive therapy resulted in fewer AEs overall and greater and earlier reductions in proteinuria over the first 6 months of treatment. These data reinforce the feasibility of using low doses of GCs and MMF to treat LN when combined with voclosporin as a third agent.Linked Compounds Count: 25

Pharmacokinetic drug interactions between voclosporin and a CYP3A inhibitor, inducer and substrate and a P-glycoprotein inhibitor and substrate were evaluated. METHODS: Voclosporin 0.4 mg kg(-1) was administered to 24 subjects in each of five studies, as follows: every 12 h (Q12H) alone and concomitantly with ketoconazole 400 mg once daily (QD); single dose before and single dose after rifampin 600 mg QD; Q12H where midazolam 7.5 mg was administered as a single dose alone before voclosporin and with last the dose of voclosporin; Q12H alone and concomitantly with verapamil 80 mg every 8 h; and Q12H with digoxin 0.25 mg QD. The noncompartmental pharmacokinetic parameters maximal concentration (Cmax ) and area under the concentration-time curve (AUC) were obtained, and geometric least squares mean ratios and 90% confidence intervals were evaluated. RESULTS: Ketoconazole increased voclosporin Cmax (6.4-fold) and AUC (18-fold); rifampin reduced voclosporin AUC (0.9-fold); voclosporin did not change exposure of midazolam or α-hydroxy-midazolam; verapamil increased voclosporin Cmax (2.1-fold) and AUC (2.7-fold); and voclosporin increased digoxin Cmax (0.5-fold), AUC (0.25-fold) and urinary excretion (0.2-fold). CONCLUSIONS: Administration of voclosporin concomitantly with strong inhibitors and inducers of CYP3A resulted in increased and decreased exposures, respectively, and should be considered contraindicated. Drug-drug interactions involving voclosporin and CYP3A substrates are not expected. Administration of voclosporin concomitantly with inhibitors and substrates of P-glycoprotein resulted in increased voclosporin and substrate exposures, respectively. Appropriate concentration and safety monitoring is recommended with co-administration of voclosporin and P-glycoprotein substrates and inhibitors.Linked Compounds Count: 33

This study aimed to evaluate the efficacy and safety of voclosporin for the treatment of LN. METHODS: This multicenter, double-blind, randomized phase 3 trial was done in 142 hospitals and clinics across 27 countries. Patients with a diagnosis of systemic lupus erythematosus and LN, according to the American College of Rheumatology criteria, who had undergone a kidney biopsy within 2 years that showed class III, IV, or V (alone or in combination with class III or IV) were eligible for this study. Patients were randomly assigned (1:1) to receive oral voclosporin (23.7 mg twice daily) or a placebo, on a background of mycophenolate mofetil (1 g twice daily) and rapidly tapered low-dose oral steroids, by use of an interactive web response system. The primary endpoint was complete renal response at 52 weeks, defined as a composite of urine protein creatinine ratio of 0.5 mg/mg or less, stable renal function (defined as estimated glomerular filtration rate [eGFR] ≥60 ml/min/1.73m2 or no confirmed decrease from baseline in eGFR of > 20%), no administration of rescue medication, and no more than 10 mg prednisone equivalent per day for 3 or more consecutive days or 7 or more days during Week 44 through Week 52 (just before the primary endpoint assessment). Safety was also assessed. Efficacy analysis was by intention to treat, and safety analysis was by randomized patients receiving at least one dose of study treatment. RESULTS: Between April 13, 2017, and October 10, 2019, 179 patients were assigned to the voclosporin group and 178 were assigned to the placebo group. The primary endpoint of complete renal response at Week 52 was achieved in significantly more patients in the voclosporin group than in the placebo group (73 [41%] of 179 patients vs 40 [23%] of 178 patients; odds ratio, 2.65; 95% confidence interval [CI] 1.64-4.27; P < 0·0001). The adverse event profile was balanced between the two groups; serious adverse events occurred in 37 (21%) of 178 patients in the voclosporin group and 38 (21%) of 178 patients in the placebo group. The most frequent serious adverse event involving infection was pneumonia, occurring in seven (4%) patients in the voclosporin group and in eight (4%) patients in the placebo group. A total of six patients died during the study or study follow-up period (one [<1%] patient in the voclosporin group and five [3%] patients in the placebo group). None of the events leading to death were considered by the investigators to be related to the study treatments. CONCLUSION: Voclosporin in combination with mycophenolate mofetil (MMF) and low-dose steroids led to a clinically and statistically superior complete renal response rate versus MMF and low-dose steroids alone, with a comparable safety profile. This finding is an important advancement in the treatment of patients with active LN.

Preclinical evidence demonstrates a more potent inhibitory effect of voclosporin on SARS-CoV-2 replication than tacrolimus in vitro. We investigated the potential antiviral effects of voclosporin on SARS-CoV-2 in immunocompromised patients. Methods: First, we conducted a prospective, randomized, open-label, proof-of-concept study in 20 kidney transplant recipients (KTRs) on tacrolimus-based immunosuppression who contracted mild to moderate SARS-CoV-2 infection. Patients were randomized to continue tacrolimus or switch to voclosporin. Second, we performed a post hoc analysis on SARS-CoV-2 infections in 216 patients with lupus nephritis (LN) on standard immunosuppression who were randomly exposed to voclosporin or placebo as part of a clinical trial that was conducted during the worldwide COVID-19 pandemic. Results: The primary end point was clearance of SARS-CoV-2 viral load and that did not differ between voclosporin-treated KTRs (median 12 days, interquartile range [IQR] 8-28) and tacrolimus-treated KTRs (median 12 days, IQR 4-16) nor was there a difference in clinical recovery. Pharmacokinetic analyses demonstrated that, when voclosporin trough levels were on-target, SARS-CoV-2 viral load dropped significantly more (ΔCt 7.7 [3.4-10.7]) compared to tacrolimus-treated KTRs (ΔCt 2.7 [2.0-4.3]; P = 0.035). In voclosporin-exposed patients with LN, SARS-CoV-2 infection was detected in 6% (7/116) compared to 12% (12/100) in placebo-exposed patients (relative risk [RR] 1.4 [0.97-2.06]). Notably, no voclosporin-exposed patients with LN died from severe SARS-CoV-2 infection compared to 3% (3/100) in placebo-exposed patients (RR 2.2 [1.90-2.54]). Conclusion: This proof-of-concept study shows a potential positive risk-benefit profile for voclosporin in immunocompromised patients with SARS-CoV-2 infection. These results warrant further investigations on voclosporin to establish an equipoise between infection and maintenance immunosuppression.

This analysis examined the efficacy and safety of voclosporin in a subgroup of the phase 3 study with proliferative lupus nephritis and high levels of proteinuria. METHODS: Participants were randomized to oral voclosporin (23.7 mg twice daily) or placebo for 12 months; all participants received MMF and low-dose glucocorticoids. This analysis includes participants with class III or IV (±class V) lupus nephritis and baseline urine protein-creatinine ratio (UPCR) ≥3 g/g. Efficacy end points included complete renal response (UPCR ≤0.5 g/g with stable eGFR, low-dose glucocorticoids, and no rescue medication), partial renal response (≥50% reduction from baseline UPCR), and UPCR over time. Safety outcomes were also assessed. RESULTS: A total of 148 participants were in the voclosporin ( n =76) and control ( n =72) arms. At 12 months, 34% and 11% of participants in the voclosporin and control arms, respectively, achieved a complete renal response (odds ratio, 4.43; 95% confidence interval [CI], 1.78 to >9.99; P = 0.001). A partial renal response was achieved by 65% of the voclosporin arm and 51% of the control arm at 12 months (odds ratio, 1.60; 95% CI, 0.8 to 3.20; P = 0.18). More voclosporin- than control-treated participants achieved UPCR ≤0.5 g/g (51% versus 26%), and voclosporin-treated participants met this end point significantly earlier (hazard ratio, 2.07; 95% CI, 1.19 to 3.60; P = 0.01). The incidence of adverse events was similar between the arms; mean eGFR values remained stable and within normal range in both arms. CONCLUSIONS: Addition of voclosporin to MMF and low-dose glucocorticoids resulted in a significantly higher proportion of participants with proliferative lupus nephritis achieving complete and partial renal responses as well as earlier reductions in proteinuria, with no evidence of worsening kidney function.Linked Compounds Count: 23
