About this study
Official title: Prospective, Randomized, Multi-Center Trial of Initial Trophic Enteral Feeding Followed by Advancement to Full-Calorie Enteral Feeding vs. Early Advancement to Full-Calorie Enteral Feeding in Patients With Acute Lung Injury (ALI) or Acute Respiratory Distress Syndrome (ARDS)
Acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) are medical conditions that occur when there is severe inflammation and increased fluids in both lungs, making it difficult for the lungs to function properly. Hospital treatment for a person with ALI/ARDS often includes the use of a breathing machine, or ventilator, until the person is able to breathe without assistance. Initiating proper nutrition through a feeding tube early in a person's hospital stay may help to improve recovery, but the optimal timing, composition, and amount of feeding treatments remain unknown. This study will evaluate whether early or delayed full-calorie feeding through a feeding tube is more effective in reducing recovery time and increasing survival rates in people with ALI/ARDS.
Read the detailed description
ALI/ARDS involves extensive inflammation in the lungs that can lead to rapid respiratory failure. These conditions are most commonly caused by pneumonia, generalized infection, or severe trauma to the lungs, but can also be less commonly caused by smoke or salt water inhalation, drug overdose, or shock.
For some people, ALI/ARDS resolves without treatment, but many severe cases result in hospitalization in the intensive care unit (ICU), where 30% to 40% of cases end in mortality. Current treatments for ALI/ARDS include assisted breathing with a ventilator, supportive care, and management of the underlying causes. Enteral feeding, in which patients receive nutrition through a feeding tube, plays an important role in treatment, too. Some recent studies have shown that enteral feeding initiated soon after a patient begins assisted breathing is associated with a shorter hospital stay and a better chance of survival than delayed enteral feeding. However, other studies have shown the opposite, and studies on optimal feeding volume and composition have shown conflicting results. This study will evaluate the effects of early versus delayed full-calorie enteral feeding on mortality, ventilator-free days, ICU-free days, and organ failure in people with ALI/ARDS.
Upon admission to the ICU, a dietary evaluation will be done on each participant to determine goal, or full-calorie, feeding rates, which will be based on body weight and daily energy consumption. Participants will also undergo baseline assessments and procedures, which will include vital sign measurements, blood draws, a frontal chest radiograph, ventilator settings, and placement of a feeding tube. Participants will be randomly assigned to receive initial enteral feedings that are either minimal (trophic) or full-calorie. All participants will begin enteral feeding within 6 hours of treatment assignment.
Participants assigned to initial minimal enteral feedings will receive feedings at 10 cubic centimeters (cc) per hour, to be continued at this rate for 144 hours, provided that the participant remains on the ventilator. After the 144 hours, the feeding rate will be advanced to full-calorie rates.
Participants assigned to initial full-calorie enteral feedings will receive feedings at 25 cc per hour, and the feeding rate will be increased by 25 cc per hour every 6 hours until the goal rate is reached. During enteral feedings, gastric residual volumes (GRVs) will be checked every 6 to 12 hours to assure acceptable levels. Participants will complete enteral feedings upon hospital discharge, Day 28 of treatment, death, or ability to achieve 48 hours of unassisted breathing.
Blood pressure, heart rate, ventilation settings, and various blood factors will be measured during treatment. Phone-based follow-up assessments will occur at Months 6 and 12 after ICU discharge and will include measurements of health-related quality of life; psychological, neurocognitive, and physical activity outcomes; healthcare utilization; and mortality.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Minimal (Trophic) FeedingBehavioural
Upon admission to the ICU, enteral feeds will be started at 10 cc per hour and continued at this rate for 144 hours. After 144 hours of trophic enteral feeds, the feeding rate will be advanced to full-calorie rates, which will continue for the duration of mechanical ventilation up to Day 28.
Full FeedingBehavioural
Upon admission to the ICU, a full-calorie feeding rate will be determined, which will be calculated to deliver 25 to 35 kcal/kg predicted body weight (PBW) each day. Enteral feeds will be initiated at 25 cc per hour. The feeding rate will be increased by 25 cc per hour every 6 hours until goal rate is achieved, which will be administered for the duration of mechanical ventilation up to Day 28.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Minimal (Trophic) Feeding and Full Feeding in people with Respiratory Distress Syndrome, Adult, run by National Heart, Lung, and Blood Institute (NHLBI) at 39 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?
The sponsor lists 4 inclusion and 28 exclusion criteria. 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 13 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 39 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. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Number of ventilator-free days (VFD) (time frame: Measured at Day 28). 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 NCT00883948, which also lists 2 linked publications.
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 13 Apr 2016; AzTrials last refreshed its copy on 8 Nov 2026.
