Clinical Trial Summary

The optimal frequency of hemodialysis treatments in patients with incident end-stage kidney disease in not known. This pilot trial will randomize patients with incident end-stage kidney disease due to chronic kidney disease progression to two different regimens of hemodialysis: i) twice-weekly hemodialysis for six weeks with adjuvant pharmacologic medications followed by thrice-weekly hemodialysis, or ii) thrice-weekly hemodialysis. The study will test feasibility of stepwise hemodialysis, and the effects of the two regimens of hemodialysis on residual kidney function.
