Albumin in Acute Ischemic Stroke Trial

Human serum albumin, at 2 g/kg, administered over 2 hours by intravenous infusion, will be compared to placebo (isovolumic normal saline) among patients with acute ischemic stroke. All patients will have a baseline stroke severity measured as NIH Stroke scale score \> 5. Patients will treated according to the best standard of care including concurrent treatment with intravenous or intra-arterial thrombolysis where appropriate. The primary outcome will be determined at 3 months. The primary hypothesis is that, using the composite outcome of a modified Rankin score 0-1 or NIH stroke scale score 0-1 at 3 months (or both), the proportion of patients with improved outcomes will be greater by 10% or more in the active treatment group. \[The current trial is termed "Part 2" and incorporates revisions to the initial protocol that were instituted after the Data Safety Monitoring Board (DSMB) suspended subject recruitment because of a safety concern after 434 subjects had been enrolled. The protocol revisions of Part 2 resulted from the study team's thorough review of the Part-1 safety data and were designed to optimize safety going forward.\]
