  • Insulin not required within 6 months of first being diagnosed with Non-insulin Dependent Diabetes Mellitus
  • No history of diabetic ketoacidosis
  • Patients may be currently treated with diet, oral hypoglycemics or insulin
  • Patients must have proteinuria defined as: Urine protein >1+ on dipstick at the initial screening visit
