Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this study is to measure glomerular filtration rate (GFR) by iohexol plasma disappearance (gold standard) and measure serum Cystatin C levels (surrogate marker) in patients enrolled in our prospective study at baseline, day 100 and 1 year after hematopoietic cell transplant and determine if these levels correlate with serum creatinine and an estimated GFR using the Modification of Diet in Renal Disease (MDRD) equation and Schwartz formula in children.

Investigators

A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.

Sites

1 registered facility, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.

  • Fred Hutchinson Cancer Research Center

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
