Primary Outcome Measures:
  • Remission status [ Time Frame: 24 months after randomization ] [ Designated as safety issue: Yes ]
    Complete remission or partial remission at 24 months after randomization will be the primary endpoint.


Secondary Outcome Measures:
  • Remission Status [ Time Frame: 6-24 months after randomization ] [ Designated as safety issue: Yes ]
    Relapse state at month 24 after randomization (Urine Protein) (UP) >3.5 after earlier CR or PR; CR(Complete Remission) or PR (Partial Remission), and CR alone at 6, 12, 18, and 24 after randomization; Time to CR or PR; Anti-PLA2R levels; Quality of life as measured by modified KDQOL; Adverse events; ESRD


Estimated Enrollment: 126
Study Start Date: November 2011
Estimated Study Completion Date: June 2016
Estimated Primary Completion Date: January 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Rituximab Treatment Arm
Patients randomized to the RTX arm will receive 1000 mg IV on Days 1 and 15. Patients who achieve complete remission at 6 months will not be retreated. A second course of RTX 1000 mg IV will be administered at study month 6 for individuals who have not achieved a complete remission, but have achieved a minimum of >25% reduction in Time 0 proteinuria. Dosing at study month 6 will be independent of CD19+ B cell count.
Drug: Rituximab
1000 mg, I.V. on Days 1 and 15 and will be retreated at month 6 independent of CD19+ B cell count
Other Name: Rituxan, MabThera
Active Comparator: Cyclosporine Treatment Arm
Patients randomized to the Cyclosporine arm will be started at a dose of CsA = 3.5 mg/kg/day p.o. divided into 2 equal doses given at 12 hour intervals. Target trough CsA blood levels are 125 to 175 ng/ml. Patients will have their doses adjusted according to their blood levels of CSA as monitored every 2 weeks until the target trough level is reached. If a complete remission is achieved by 6 months, CSA will be tapered and discontinued over a three-month period. If after 6 months there has not been a reduction in proteinuria of at least 25% of baseline values, the drug will also be discontinued. If there has been a >25% reduction in baseline proteinuria (but not complete remission) the CSA will be continued for an additional 6 months.
Drug: Cyclosporine
Patients randomized to the Cyclosporine arm will be started at a dose of (CsA = 3.5 mg/kg/day p.o. divided into 2 doses for 12 months). Target trough CsA blood levels, as determined in whole blood by HPLC, are 125 to 175 ng/ml. A persistent and otherwise unexplained increase in serum creatinine >30% would prompt an approximate 25% dose reduction of CSA, aiming for a corresponding 25% reduction in CSA trough level. If with this dose reduction the creatinine does not return to within 30% of baseline levels within 3 weeks, then a second dose reduction of approximately 25% with similar reduction in CSA trough level will be used. If the creatinine does not fall to baseline values with this second dose reduction, the drug will be discontinued. At the end of 12 months, Cyclosporine will be tapered by 1/3 of the maintenance dose monthly and hence discontinued after 3 months.

Ages Eligible for Study:   18 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria

  • Idiopathic MN with diagnostic biopsy
  • Female, must be post-menopausal, surgically sterile or practicing a medically approved method of contraception(no birth-control pill)
  • Must be off prednisone or mycophenolate mofetil for >1 month and alkylating agents for >6 months.
  • ACEi and/or ARB, for >3 months prior to randomization and adequate blood pressure (target BP <130/80 mmHg in >75% of the readings, but subjects with BP <140/80 mmHg in >75% of the readings will be eligible). Patients with documented evidence of >3 months treatment with maximal angiotensin II blockade, on an HMG-CoA reductase inhibitor, and BP control (BP <140/80 mmHg in >75% of the readings) who remain with proteinuria >5g/24h may enter and be randomized to RTX/CSA without the need of the run-in/conservative phase of the study.
  • Proteinuria >5g/24h on two 24-hour urine collection collected within 14 days of each other
  • Estimated GFR ≥40 ml/min/1.73m2 while taking ACEi/ARB therapy OR quantified endogenous creatinine clearance >40 ml/min/1.73m2 based on a 24-hour urine collection.

Exclusion Criteria

  • Presence of active infection or a secondary cause of MN (e.g. hepatitis B, SLE, medications, malignancies). Testing for HIV, Hepatitis B and C should have occurred <2 years prior to enrollment into the study.
  • Type 1 or 2 diabetes mellitus: to exclude proteinuria secondary to diabetic nephropathy. Patients who have recent history of steroid induced diabetes but no evidence on renal biopsy performed within 6 months of entry into the study are eligible for enrollment.
  • Pregnancy or breast feeding for safety reasons
  • History of resistance to CSA (or other calcineurin inhibitors, e.g. tacrolimus), RTX or alkylating agents (e.g. Cytoxan). Patients who previously responded to CSA/CNI, RTX or alkylating agents with either a CR or PR but relapsed off CSA/CNI after 3 months or relapsed off RTX or alkylating agent after 6 months are eligible.
