Trial Outcomes & Findings for Citrulline in Severe Sepsis (NCT NCT01474863)

NCT ID: NCT01474863

Last Updated: 2017-06-05

Results Overview

Worst Value of Index measuring blood pressure hourly through study infusion (day 4). Vasopressor index is mean arterial blood pressure divided by catecholamine index (the catecholamine index is a dimensionless variable calculated as (dopamine dose × 1) + (dobutamine dose × 1) + (adrenaline dose × 10) + (noradrenaline × 100) + (phenylephrine dose × 100), where all doses are expressed in ug/kg/min). (Higher is better)

Measure
Low Dose Citrulline
Low Dose Citrulline Low Dose Citrulline: Initial intravenous bolus of 10mg/kg (to a maximum of 1500mg) L-citrulline over 10 minutes. Immediately after the initial bolus, a continuous intravenous infusion of L-citrulline at 4.5mg/kg (max 350mg) per hour will be administered through a dedicated intravenous line or port of a multilumen catheter for 4 days.
Placebo
Placebo IV infusion Placebo: D5W IV fluids at isovolumetric rate (about 15ml/hr)
High Dose Citrulline
High Dose Citrulline High Dose Citrulline: Initial intravenous bolus of 20mg/kg (to a maximum of 1500mg) L-citrulline over 10 minutes. Immediately after the initial bolus, a continuous intravenous infusion of L-citrulline at 9mg/kg (max 700mg) per hour will be administered through a dedicated intravenous line or port of a multilumen catheter for 4 days
