Collaborator:
National Institutes of Health (NIH)
Information provided by (Responsible Party):
Todd Rice, Vanderbilt University
  Purpose
This is a randomized, double-blind, placebo-controlled, phase 2 study to evaluate biochemical, clinical, and safety effects of 2 doses of intravenous L-citrulline compared to placebo in patients with severe sepsis at risk for or with acute lung injury. The hypothesis is that intravenous L-citrulline will decreased the development or progression of acute lung injury in patients with severe sepsis compared to placebo.

Condition Intervention Phase
Severe Sepsis Acute Lung Injury Drug: High Dose Citrulline Drug: Placebo Drug: Low Dose Citrulline Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Prevention
Official Title: Prospective, Randomized, Double-Blind, Placebo-Controlled Phase II Trial of Intravenous Citrulline to Prevent or Mitigate Acute Lung Injury in Patients With Severe Sepsis

Primary Outcome Measures:
  • Vasopressor Dependency Index [ Time Frame: day 4 ]
    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)


Enrollment: 72
Study Start Date: August 2012
Study Completion Date: March 2016
Primary Completion Date: March 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Low Dose Citrulline
Low Dose Citrulline
Drug: 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 Comparator: Placebo
Placebo IV infusion
Drug: Placebo
D5W IV fluids at isovolumetric rate (about 15ml/hr)
Active Comparator: High Dose Citrulline
High Dose Citrulline
Drug: 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
