NCT01221181

  Purpose

This is an investigator initiated, single site study to determine whether eculizumab, a drug approved by the FDA for another indication, is a safe and effective treatment for dense deposit disease (DDD) and C3 nephropathy.

All enrolled subjects will receive eculizumab treatment for one year. There will be 29 study visits over 53 weeks. The goal is to determine whether this treatment will improve kidney function, as evidenced by less protein in the urine and improved lab results.

An EXTENSION TREATMENT PHASE has been added. After completing the study, patients are followed with labs every four weeks as per standard of care. If labs suggest a relapse, they will be allowed to continue on therapy at the previous dosage until this drug receives FDA approval for this indication. Treatment intervals and dosage are identical to the original study.

Primary Outcome Measures:
  • Complete remission [ Time Frame: after 1 year of therapy ] [ Designated as safety issue: No ]
    The primary end point is complete remission, defined as remission of proteinuria to <500 mg/day with normal renal function.


Secondary Outcome Measures:
  • Partial remission [ Time Frame: after 1 year of therapy ] [ Designated as safety issue: No ]
    Partial remission, a secondary endpoint, will be defined as reduction in proteinuria by at least 50% and to <2 g/day with stable renal function (i.e. no more than a 20% increase in serum creatinine).

  • Improvement in histologic parameters [ Time Frame: after 1 year of therapy ] [ Designated as safety issue: No ]
    Improvement in histologic parameters, including percentage of non-affected glomeruli, interstitial fibrosis, intensity of C3 staining of immunoflourescence, and amount of electron dense deposits by electron microscopy.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Adult patients with biopsy proven DDD or C3 nephropathy, at least 18 years of age
  • 24-hour urine protein > 1000 mg/day, urine protein:creatinine ratio > 1.0, or acute renal failure (defined as > 50% increase in serum creatinine from baseline)
  • Willing and able to sign informed consent
  • Patients of childbearing age must agree to use birth control
  • Patients must be willing to be vaccinated against meningococcal disease or have documentation of previous vaccination against meningococcal disease

Exclusion Criteria:

  • Patients under 18 years of age
  • Patients unable to sign informed consent
  • Patients having received rituximab or another monoclonal antibody within 6 months of the trial
  • Patients currently taking and unable to discontinue other immunomodulatory therapies (e.g. cyclosporine, high-dose steroids, mycophenolate mofetil) unless these other therapies are indicated for prophylaxis against transplant rejection (e.g. stable doses of mycophenolate mofetil and/or calcineurin inhibitor). Patients on chronic steroid therapy who are unable to taper down to <10 mg/day will be excluded.
  • Patients of childbearing age who refuse to use birth control
  • Patients with a baseline eGFR less than 30 ml/min/1.73m2
  • Patients with other renal diseases (e.g. diabetic nephropathy, renal vascular disease) that would interfere with interpretation of the study.
  • Patients with comorbid conditions that would interfere with completion of the trial (malignancies, CHF, recent myocardial infarction).
  • Patients with known contraindications to the use of eculizumab, including refusal to receive N. meningitidis vaccine prior to therapy
