Summary:

      This is an early phase (phase IIa), randomized, multi-center study in subjects with acute
      lung injury (ALI) or acute respiratory distress syndrome (ARDS). The purpose of this study is
      to investigate the safety of GSK2586881 and to determine what effects it has on people with
      Acute Lung Injury (ALI) or Acute Respiratory Distress Syndrome (ARDS).

      The study has two parts: Part A will be an open-label investigation in five subjects. Part B
      will be a double-blind, placebo controlled investigation and will involve approximately 60
      subjects.

          -  Diagnosis of ALI with acute onset of PaO2/FiO2 ratio less than or equal to 300, and
             bilateral infiltrates consistent with pulmonary edema on frontal chest radiograph. The
             infiltrates may be patchy, diffuse, homogeneous, or asymmetric, and requirement for
             positive pressure ventilation via an endotracheal tube, and no clinical evidence of
             left atrial hypertension

             treatment not requiring resuscitative measures with stable pressor requirements. In
             this study low-dose arginine vasopressin is not considered a pressor, and is permitted
             in Parts A and B.

             hours before dosing begins

             form.

          -  QTcB or QTcF less than 450 msec; or QTc less than 480 msec in subjects with Bundle
             Branch Block.

             less than or equal to 1.5 x ULN.

        Exclusion Criteria:

          -  Subjects whose clinical condition is deteriorating rapidly or any subject for whom the
             investigator does not consider there is a reasonable expectation that they will be
             able to complete the study.
