Ischemic Stroke

stroke
Brief summary
The goal of the trial is to determine whether human albumin, administered within 5 hours of symptom onset, improves the 3-month outcome of subjects with acute ischemic stroke.
Detailed description
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. \[The current trial is termed Part 2 and incorporates revisions to the initial protocol that were instituted after the Data Safety Monitoring Board (DSMB) suspended subject recruitment because of a safety concern after 434 subjects had been enrolled. The protocol revisions of Part 2 resulted from the study team's thorough review of the Part-1 safety data and were designed to optimize safety going forward.\]

* Episode/exacerbation of congestive heart failure (CHF) from any cause in the last 6 months. An episode of congestive heart failure is any heart failure that required a change in medication, diet or hospitalization. * Known valvular heart disease with CHF in the last 6 months. * Severe aortic stenosis or mitral stenosis. * Cardiac surgery involving thoracotomy (e.g., coronary artery bypass graft (CABG), valve replacement surgery) in the last 6 months. * Acute myocardial infarction in the last 6 months. * Signs or symptoms of acute myocardial infarction, including ECG findings, on admission. * Baseline elevated serum troponin level on admission (\>0.1 mcg/L) * Suspicion of aortic dissection on admission. * Acute arrhythmia (including any tachycardia - or bradycardia) with hemodynamic instability. * Findings on physical examination of any of the following: (1) jugular venous distention (JVP \> 4 cm above the sternal angle); (2) 3rd heart sound; (3) resting tachycardia (heart rate \> 100/min) attributable to congestive heart failure; (4) abnormal hepatojugular reflux; (5) lower extremity pitting edema attributable to congestive heart failure; and/or (6) definite chest x-ray evidence of pulmonary edema. * Current acute or chronic lung disease requiring supplemental chronic or intermittent oxygen therapy. * Historical Modified Rankin Score (mRS) ≥2. Patients who live in a nursing home or who are not fully independent for activities of daily living immediately prior to the stroke are not eligible for the trial. * In-patient stroke. I.e., patients with a stroke occurring as a complication of hospitalization for another condition, or as a complication of a procedure. * Planned acute use of intra-arterial (IA) tPA or acute endovascular intervention (e.g., stenting, angioplasty, thrombus retrieval device use) must conform to the following criteria: (1) begin within 5 hours of symptom onset, and (2) finish within 7 hours of symptom-onset. * Fever, defined as core body temperature \> 37.5° C (99.5°F). * Serum creatinine \> 2.0 mg/dL or 180 µmol/L. * Profound dehydration. * Evidence of intracranial hemorrhage (intracerebral hematoma (ICH), subarachnoid hemorrhage (SAH), epidural hemorrhage, acute or chronic subdural hematoma (SDH)) on the baseline CT or MRI scan. * History of allergy to albumin. * History of latex rubber allergy. * Severe chronic anemia with Hgb \< 7.5 g/dL * Pregnancy, breastfeeding or positive pregnancy test.

The Number of Participants With a Score on the mRS 0-1 at 90 Days.
The mRS ranges from 0-6 representing perfect health without symptoms to death. 0 = No symptoms at all. 1 = No significant disability. Able to carry out all usual duties and activities. 2 = Slight disability. Unable to carry out all previous activities but able to look after own affairs without assistance. 3 = Moderate disability. Requires some help, but able to walk unassisted. 4 = Moderately severe disability. Unable to walk unassisted and unable to attend to own bodily needs without assistance. 5 = Severe disability. Bedridden, incontinent, and requires constant nursing care and attention. 6 = Dead.
Time frame: at 90 days
Population: Intent to Treat population - All subjects randomized into the study are included and analyzed based on the treatment arm to which they were randomized.

Trailmaking A
The Trail Making Test is a neuropsychological test of visual attention and task switching that is thought to be sensitive to the presence of cerebral dysfunction. It is a timed test consisting of two parts where the subject is asked to draw a trail made by connecting numbers in sequential order (part A) and then in part B the combination of numbers and letters. Scoring is calculated separately for Parts A and B but both scores are provided as the minutes and seconds it takes for the subject to complete ach part. Normally, the entire test (A and B) can be completed in 5-10 minutes.
Time frame: at 90 days
Population: Participants were excluded if the Tail Making Test was not assessed.
