Nutritional Adequacy Therapeutic Enhancement in the Critically Ill. The NUTRIATE Study

Study Overview
=================
Brief Summary
-----------------
This is a multi-center, parallel group, placebo-controlled and active-compared, randomized study to assess the ability of GSK962040 to enhance the delivery of enteral feed to critically ill subjects that are predisposed to developing feeding intolerance (e.g., percentage of goal volume); enhance gastric emptying in this population; and provide preliminary evidence of the drug's effect on outcomes of therapy (length of stay in the Intensive Care Unit [ICU], time on ventilator, ICU acquired infections, and 60-day mortality). Other aims are evaluation of GSK962040 safety, tolerability and pharmacokinetics upon repeat dosing in a critically ill population. After meeting eligibility criteria, male and female subjects will be randomized to either receive GSK962040 (50 milligram [mg]) once daily (OD) via naso-gastric (NG) or orogastric (OG) feeding tube (oral solution), or placebo by the same route. If subjects develop intolerance to enteral feeding at any point up to Dose 5 of study medication (inclusive), study treatments will switch such that those originally receiving GSK962040 will receive metoclopramide (10 mg, intravenous [iv], every 6 hours) and those subjects originally randomized to receive placebo will receive GSK962040 (50 mg, via NG, OD). Additionally, if subjects develop intolerance prior to any treatment, they will be randomized to receive either GSK962040 (50 mg, via NG, OD) or metoclopramide (10 mg, iv, every 6 hours). The study will consist of a screening/baseline assessment, a treatment period (up to 7 days in duration), and a 4-day post treatment safety follow-up assessment. The duration of each subject's participation in the study from screening to follow-up safety assessment will be up to approximately 2 weeks. In addition, mortality will be assessed 60 days after admission to the ICU.
