Detailed Description:

The acute respiratory distress syndrome (ARDS) is a form of severe acute lung injury (ALI) characterized by hypoxemic respiratory failure (the lungs are unable to absorb oxygen to the arterial blood) and non-cardiogenic pulmonary edema (accumulation of fluid in the lungs). The syndrome may be caused by direct or indirect injury to the lungs. It is associated with a mortality rate of up to 40-50%. There are no marketed pharmacologic therapies for this devastating syndrome.

This study aims to assess the safety, tolerability and pharmacodynamics of GSK2586881, a recombinant human angiotensin converting enzyme type 2 (rhACE2).

ACE2 is involved in the Renin-Angiotensin System (RAS), which controls blood pressure, electrolytes and intravascular fluid volume. A key function of rhACE2 is believed to be the cleavage of Angiotensin II (Ang II) to Ang (1-7), which have opposing physiological roles. Elevated levels of Ang II are associated with vasoconstriction, inflammation, fibrosis, vascular leak, and sodium absorption. Ang (1-7) appears to be a counterregulatory protein in the RAS; associated with vasodilation, anti-proliferation, antiinflammation, and reduced vascular leak. It has been observed that levels of Ang II are increased in humans with ALI/ ARDS. It is expected that the reduction of Ang II should have a positive impact on ALI and ARDS.
