ClinicalTrials.gov Identifier:
NCT01332799

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
Roberto S Kalil, University of Iowa
  Purpose
Cardiovascular disease is the leading cause of mortality in kidney transplantation. The enzyme xanthine oxidase may play an important role in the cardiovascular disease of kidney transplant recipients. Inhibiting this enzyme with allopurinol may improve vascular health and protects against cardiovascular complications.

Condition Intervention Phase
Complications of Renal Transplant Drug: allopurinol or placebo Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Xanthine Oxidase Inhibition in Renal Transplant Recipients
