About this study
Official title: Phase III Study on the Efficacy of Glutamine Dipeptide-Supplemented Parenteral Nutrition in Surgical ICU Patients
Relative glutamine (GLN) deficiency may contribute to morbidity and mortality in surgical intensive care unit (SICU) patients. During critical illness, GLN utilization by the immune system, gut mucosa and other tissues exceeds endogenous production and plasma GLN concentrations decrease, which may contribute to cellular dysfunction and increase nosocomial infection risk and mortality. Conventional GLN-free parenteral nutrition (PN) has a limited impact on SICU outcomes and does not repair the GLN deficit. Recent pilot data show that GLN dipeptide-supplemented PN decreases nosocomial infections and improves clinical outcomes in SICU patients. The process of benefit is poorly understood, but animal and human data suggest that GLN treatment correlates with a) up-regulation of cytoprotective molecules in blood and tissues [e.g, GSH, specific heat shock proteins (HSPs) and GLN]; and b) improved epithelial barrier defenses and immune cell number and function. Properties of L-GLN limit provision in solution, but the GLN dipeptide alanyl-GLN (AG) confers stability and solubility in PN (AG-PN). Investigators propose a multicenter, double-blind, randomized, controlled phase III trial based on our pilot data to test the hypothesis that AG-PN improves clinical outcomes in SICU patients requiring PN after cardiac, vascular or colonic operations. Subjects will receive either standard GLN-free PN or isocaloric, isonitrogenous, AG-PN until enteral feeds are established. Specific Aim 1 is to determine whether AG-PN decreases hospital mortality, nosocomial infection and other important indices of morbidity. Specific Aim 2 is to obtain novel, mechanistically relevant observational data in the Aim 1 subjects on whether AG-PN a) increases serial blood levels of GSH, HSP-70 and -27, and GLN; b) decreases the presence in serum of the bacterial products flagellin and LPS and the adaptive immune response to these mediators; and c) improves key indices of innate/adaptive immunity. This study is designed to delineate the clinical benefit of a major new nutrition support strategy in high-risk SICU patients.

Read the detailed description
Overview: Relative deficiency of glutamine (GLN) appears to contribute to morbidity and mortality in surgical intensive care unit (SICU) patients, but conventional nutrition support does not repair this deficit. GLN requirements increase during critical illness when utilization by the immune system, gut mucosa and other tissues exceeds endogenous production. GLN depletion under these conditions may contribute to hospital morbidity and mortality. Conventional parenteral nutrition (PN) does not contain GLN and thus does not prevent GLN depletion in catabolic patients. However, a pilot study and other reports strongly suggest that GLN-supplemented PN improves metabolic and clinical outcomes in critically ill patients. Underlying mechanisms for GLN action are poorly understood, but may involve systemic upregulation of the cytoprotective molecules glutathione (GSH), specific heat shock proteins (HSP) and GLN itself, improved gut barrier defenses, and improved innate and/or adaptive immune function. Properties of L-GLN limit provision in PN, but the dipeptide alanyl-glutamine (AG) confers stability and solubility in PN solutions. The pilot study demonstrated a marked decrease in nosocomial infection, improved indices of organ function, and a possible decrease in hospital mortality in SICU patients receiving AG-supplemented PN (AG-PN) versus standard, GLN-free PN (STD-PN). Investigators propose a multi-center, double-blind, controlled, Phase III trial, based on a pilot study, that will determine the effect of parenteral GLN on important clinical outcomes in patients requiring SICU care and PN after cardiac, vascular or colonic surgery. Investigators also propose to obtain needed hypothesis-generating, descriptive data from the Aim 1 study subjects to inform subsequent, truly mechanistic studies of GLN action in animal and human models of surgical critical illness. Study subjects will be randomized on an intent-to-treat basis to receive AG-PN or isonitrogenous, isocaloric STD-PN until enteral feeding is established.
Hypotheses:
- SICU patients receiving PN supplemented with GLN dipeptide (AG-PN) will demonstrate improved clinical outcomes compared to patients receiving STD-PN.
- Administration of AG-PN in the Aim 1 study subjects: a) increases serial blood levels of specific cytoprotective molecules and improves systemic redox status; b) is associated with decreased serum positivity for the bacterial products flagellin and lipopolysaccharide ( LPS) and the adaptive immune response to these mediators; and c) improves key indices of innate/adaptive immunity.
Specific Aims:
Aim 1: To perform a Phase III randomized controlled trial (RCT) to determine whether AG-PN decreases hospital mortality, nosocomial infections, and other indices of hospital morbidity versus STD-PN in SICU patients. The study will test whether AG-PN: decreases hospital mortality and the incidence of nosocomial infection (primary endpoints) in SICU patients after cardiac, vascular or colonic surgery. We will also determine whether AG-PN decreases total hospital infections, bloodstream infections (BSI), infections due to Staphylococcus aureus or fungal species, the number of days patients require mechanical ventilation, the SICU and total hospital length of stay and the 6-month mortality rate (secondary endpoints).
Aim 2: To determine in the Aim 1 study subjects whether AG-PN: a) increases systemic blood concentrations of the cytoprotective molecules GSH, HSP-70, HSP-27 and GLN and improves systemic GSH and cysteine redox status; b) is associated with decreased serum positivity for the bacterial products flagellin and LPS and titers of anti-flagellin and anti-LPS immunoglobulin M (IgM), immunoglobulin A (IgA) and immunoglobulin G (IgG); and c) improves key indices of innate/adaptive immune cell function.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Glutamine dipeptide with 15% Clinisol and 15% Clinisol in people with Critical Illness, run by Emory University at 5 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 13 Feb 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hospital Mortality Rate (time frame: Current Hospitalization (Up to 6 Months)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00248638, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jan 2018; AzTrials last refreshed its copy on 8 Nov 2026.
