Brief Summary

This study is designed to evaluate the safety and efficacy of fostamatinib in hospitalized adult participants with acute respiratory distress syndrome (ARDS).

Detailed Description

This is a randomized, double-blind, placebo-controlled phase 2 study for long-term evaluation of fostamatinib for the treatment of adult patients with acute respiratory distress syndrome. Subjects will be randomly assigned 1:1 to either standard of care treatment plus fostamatinib or standard or care plus placebo. Th study drug will be taken twice daily for 14 days.

The primary objective will be to evaluate drug safety in hospitalized patients with severe ARDS. Other objectives include assessment of the efficacy and clinically relevant endpoints, such as mortality and effects on resolution of this disease entity. The ability of fostamatinib to impact the short term and long term outcomes for patients with ARDS will be directly evaluated.
