Study summary

OBJECTIVES: I. Determine the effect of SYNSORB Pk therapy on mortality and frequency of severe extrarenal complications observed in children with acute stage E. coli-associated hemolytic uremic syndrome.

II. Determine the effect of SYNSORB Pk therapy on the need for the duration of dialysis in these patients.

III. Determine the effect of SYNSORB Pk therapy on the recovery of renal function and resolution of urinary abnormalities in these patients.

Read the detailed description

PROTOCOL OUTLINE: This is a randomized, double blind, placebo controlled, multicenter study. Patients are randomized to receive either SYNSORB Pk or placebo.

Patients receive oral SYNSORB Pk or placebo three times daily for 7 days. Patients are followed on days 7, 14, 28, and 60 after discharge from the hospital.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 1, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
