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.

Gastric emptying is the end-result of a complex and carefully regulated series of events which follow the ingestion of a meal, each of which is dependent on the other and subject to neurohormonal control. Motilin is an endogenous peptide, produced mainly in the duodenum, whose physiological action is mediated by motilin receptors located on enteric neurons, peripheral terminals of the vagus, and on the smooth muscle of the gut. Motilin and non-peptide agonists at motilin receptors increases the gastric emptying rate and therefore provide a potential approach to the treatment of a range of clinical conditions in which delayed gastric emptying is thought to be part of the physiopathology and may be contributory to symptoms. Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by degeneration of nigrostriatal dopaminergic neurones. It affects 1.5% of the global population over 65 years of age. Cardinal symptoms comprise bradykinesia, rigidity, resting tremors and postural instability. Gastrointestinal dysfunction, including gastroparesis, is a frequent feature of PD affecting approximately 90% of patients, and is caused by autonomic dysfunction as well as an adverse effect of antiparkinsonian drug therapy. The therapeutic mainstay for PD treatment is the neutral amino acid L-3,4-dihydroxyphenylalanine (L-DOPA), a dopamine prodrug, as it provides the most rapid and effective symptomatic control of motor impairment in PD. The primary determinant of L-DOPA bioavailability is gastric emptying (GE); delays in GE slow delivery of L-DOPA to its proximal small intestinal absorption sites, increasing the extent of presystemic metabolism, and leading to slowed and diminished absorption.
