Overview

About this study

The purpose of this study is to assess the efficacy of voclosporin compared with placebo in achieving renal response after 52 weeks of therapy in subjects with active lupus nephritis.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

-Subjects with evidence of active nephritis, defined as follows:

  • Kidney biopsy result within 2 years prior to screening indicating Class III, IV-S, IV-G (alone or in combination with Class V), or Class V LN with a doubling or greater increase of UPCR within the last 6 months to a minimum of ≥1.5 mg/mg for Class III/IV or to a minimum of ≥2 mg/mg for Class V at screening. Biopsy results over 6 months prior to screening must be reviewed with a medical monitor to confirm eligibility.

OR

  • Kidney biopsy result within 6 months prior to screening indicating Class III, IV-S or IV-G (alone or in combination with Class V) LN with a UPCR of ≥1.5 mg/mg at screening.

OR

  • Kidney biopsy result within 6 months prior to screening indicating Class V LN and a UPCR of ≥2 mg/mg at screening.
    • Women of childbearing potential must have a negative serum pregnancy test at screening and a negative urine pregnancy test at baseline.

Exclusion Criteria:

  • Estimated glomerular filtration rate (eGFR) of ≤45 mL/minute at screening.
  • Current or medical history of:
    • Congenital or acquired immunodeficiency.
    • In the opinion of the Investigator, clinically significant drug or alcohol abuse within 2 years prior to screening.
    • Malignancy within 5 years of screening, with the exception of basal and squamous cell carcinomas treated by complete excision.
    • Lymphoproliferative disease or previous total lymphoid irradiation.
    • Severe viral infection or known HIV infection.
    • Active tuberculosis (TB), or known history of TB/evidence of old TB if not taking prophylaxis with isoniazid.
  • Other known clinically significant active medical conditions, such as:
    • Severe cardiovascular disease, liver dysfunction or chronic obstructive pulmonary disease or asthma requiring oral steroids or any other overlapping autoimmune condition for which the condition or the treatment of the condition may affect the study assessments or outcomes.

  • Voclosporin is a novel calcineurin inhibitor intended for prevention of organ graft rejection and treatment of lupus nephritis. Pharmacokinetic drug interactions between voclosporin and a CYP3A inhibitor, inducer and substrate and a P-glycoprotein inhibitor and substrate were evaluated. Read More on PubMed
  • Voclosporin is a novel calcineurin inhibitor intended for prevention of organ graft rejection and treatment of lupus nephritis. These studies evaluated the effect of renal or hepatic impairment on pharmacokinetics of voclosporin. Thirty-three subjects were enrolled into 1 of 4 groups based on renal function as defined by creatinine clearance and 18 subjects were enrolled into 1 of 3 groups based on hepatic function defined by Child-Pugh classes. Voclosporin 0.4 mg/kg was administered orally. Geometric mean ratios (renal/hepatic impairment-to-normal) and 90% confidence intervals for Cmax and AUC were calculated. A default no-effect interval of 80-125% was set. Although 90% confidence intervals exceeded the no-effect intervals for both parameters, individual Cmax and AUC plots indicate almost complete overlapping range of values for mild and moderate renal impairment and normal subjects. Severe renal impairment resulted in a 1.5-fold increase in AUC without an increase in Cmax . Mild to moderate hepatic impairment resulted in a 1.5- to 2-fold increase in voclosporin exposure. Voclosporin can be administered safely to patients with mild to moderate renal impairment without dose modification. Appropriate safety monitoring with concentration-based adjustments in transplantation are recommended for patients with severe renal impairment, and for patients with hepatic impairment.

  • Voclosporin (VCS) is a novel calcineurin (CN) inhibitor intended for prevention of organ graft rejection and treatment of lupus nephritis. These studies evaluated the single ascending dose pharmacokinetics (PK) and pharmacodynamics (PD, CN activity) of VCS and the effect of food. VCS was administered orally in single doses of 0.25 through 4.5 mg/kg in 62 subjects in the single ascending dose study and as a single oral 1.5 mg/kg dose to 18 subjects after fasting, consumption of a low-fat and high-fat meal. Non-compartmental PK, PD, and PKPD correlation were evaluated. Following single oral doses, systemic exposure increased in a linear manner and demonstrated 1:1 dose-proportional, first-order linear PK above 1.5 mg/kg. VCS inhibited CN activity in a dose-related fashion with maximal inhibition peaking at 3.0 mg/kg. PKPD correlation indicated an EC50 of 78.3 ± 6.8 ng/mL. Administration of VCS with a low-fat and high-fat meal decreased C(max) by 29% and 53%, respectively, and AUC(inf) by 15% and 25%, respectively. Following ascending single doses of VCS, exposure increased in a linear fashion. A food effect on exposure was demonstrated, with a more pronounced effect following a high-fat meal. VCS concentrations were also found to correlate with CN activity. Read More on PubMed
  • Severe lupus nephritis is an aggressive disease that requires an aggressive approach to treatment. Recent randomized clinical trials showed that mycophenolate mofetil compared favorably with cyclophosphamide (traditional approach) for remission induction. Consequently, mycophenolate mofetil is now commonly recommended as first-line therapy. Nevertheless, the role of mycophenolate mofetil in treating severe lupus nephritis is unclear, because such patients were excluded from these trials. With this limitation as background, this work addresses the question of mycophenolate mofetil for induction therapy for severe lupus nephritis. We performed a systematic review of the outcomes of treating severe lupus nephritis with mycophenolate mofetil or cyclophosphamide. Because no studies directly addressed this question, these data were extracted from the published literature or obtained by personal communications from investigators. There is no universally accepted definition, and therefore, severe lupus nephritis was arbitrarily defined by renal histology, resistance to therapy, or level of kidney function at presentation. For each trial analyzed, we determined the partial and complete remission rates. Long-term outcomes were compared when available. The pooled results suggest that mycophenolate mofetil and cyclophosphamide are equally effective in inducing remission of severe lupus nephritis. However, relapse rates and risk of developing ESRD were higher for mycophenolate mofetil compared with cyclophosphamide. In conclusion, in the short term, mycophenolate mofetil and cyclophosphamide are about equal in inducing remission. However, long-term outcomes suggest better preservation of kidney function and fewer relapses with cyclophosphamide therapy. Therefore, mycophenolate mofetil should not yet be considered the induction drug of choice for severe lupus nephritis. Read More on PubMed
