No results posted yet for this study

Summary

The purpose of this study is to determine whether oral sevelamer carbonate binds advanced glycation end products (AGEs) in the gastrointestinal (GI) tract of patients with diabetic nephropathy leading to decrease body AGE load and therefore decreases the inflammation and oxidative stress in these patients.

Conditions

  • Diabetic Nephropathy

Interventions

DRUG

Sevelamer Carbonate

This is a 4 month, prospective, comparative, crossover study. The study will be conducted in 20 patients with stage II, III or stage IV diabetic nephropathy. Patients will be randomized 1:1 to receive either 1,250 mg of calcium carbonate TID with meals (control arm) or Sevelamer Carbonate 1,600 mg (two 800 mg tablets) with meals. Each group of 10 subjects will take the assigned drug for 8 weeks. Following the 8 week treatment period, subjects will discontinue the assigned drug for a one week washout period. Following the washout period, those who were taking calcium carbonate will be crossed over to Sevelamer Carbonate therapy and those who were receiving Sevelamer Carbonate will be crossed over to calcium carbonate for a final 8 week treatment phase.
