Conditions:

Focal Glomerulosclerosis

Eligibility:

All Genders

2-40 years

Phase:

PHASE1

Brief Summary

The current management of primary FSGS is predicated on the assumption that the disease is caused by an immune-mediated disturbance in glomerular barrier function. Therefore, most treatment protocols ...

Eligibility Criteria

Inclusion

  • Inclusion Criteria:
  • Aged 2-42 years at onset of proteinuria
  • Aged ≤ 42 years at time of randomization (randomization date before 43rd birthday)
  • Estimated glomerular filtration rate (GFR) ≥ 40 ml/min/1.73 m2 at most recent measurement prior to randomization
  • For patients \< age 18 years: Schwartz formula
  • For patients ≥ age 18 years: Cockroft-Gault formula
  • Up/c \> 1.0 g/g creatinine on first morning void at time of randomization
  • Biopsy confirmed as primary FSGS (including all subtypes) by study pathologist.
  • Steroid resistance: During the last treatment course with high dose steroids prior to randomization, the patient must have demonstrated steroid resistance defined below and not have had a complete remission of proteinuria (Up/c \< 0.2 or dipstick urine protein negative/trace) subsequently. The course of steroid treatment that defines resistance must be the same or equivalent to at least 4 weeks of every day dosing with a minimum cumulative dose of 56 mg/kg or 1680 mg of prednisone or its equivalent.
  • May be taking angiotensin-converting enzyme inhibitor (ACEI), angiotensin receptor blocking agent (ARB), vitamin E, or lipid lowering therapy
  • Willingness to comply with clinical trial protocol, medications, and follow-up visits, etc.
  • Screen failure in FSGS-CT based on prior treatment with excluded medication
  • Treatment failure in FSGS-CT based on failure to achieve remission after 26 weeks or 52 weeks of test therapy, i.e., cyclosporine or mycophenolate mofetil (MMF) + oral dexamethasone pulses
  • Exclusion Criteria
  • Secondary FSGS
  • Treated with cyclophosphamide, chlorambucil, levamisole, methotrexate, nitrogen mustard, or other immunosuppressive medications in the 30 days prior to randomization
  • Lactation, pregnancy, or refusal of birth control in women of child bearing potential
  • Participation in another therapeutic trial concurrently or for 30 days prior to randomization
  • Active/serious infection (including, but not limited to hepatitis B or C, HIV)
  • Malignancy
  • Systemic lupus erythematosus (SLE) or multiple sclerosis
  • Hepatic disease defined as serum AST/ALT \> 2.5X the upper limit of normal
  • Patients with blood pressure \> 140/95 or \> 95th percentile for age/height while receiving maximal doses of 3 or more antihypertensive agents.
  • Diabetes mellitus (DM) type I or II.
  • Hematocrit \< 30%
  • Organ transplantation
  • Obesity (based on estimated dry weight at disease onset prior to steroid therapy) defined as:
  • Body mass index (BMI) \> 97th percentile for age if aged 2-20 years
  • BMI \> 40 kg/m2 if aged ≥ 21 years
  • Allergy to study medications
  • Inability to consent/assent
