| Subarachnoid Hemorrhage | Drug: 25% human albumin | Not Applicable |
An estimated 37,500 people in the United States have subarachnoid hemorrhage (SAH) every year. SAH is usually secondary to a brain aneurysm that has burst. In SAH the bleeding accumulates around the lining of the brain. SAH is associated with a 51percent mortality rate, and one third of survivors are left functionally dependent. Cerebral vasospasm, which is a delayed narrowing of the cerebral arteries following SAH, has been identified as the most important reason for neurological deterioration and bad outcome in cases of SAH. Cerebral vasospasm may be caused by multiple mechanisms.
Treatment with a neuroprotective agent, such as human albumin (HA), may be beneficial for prevention of cerebral vasospasm and improved clinical outcome in patients with SAH. HA is a major protein found in blood and is responsible for maintaining fluid balance in the vascular system (blood vessels). The purpose of this study was to determine the safety and tolerability of 25 percent HA therapy in patients with SAH. This open-label, dose-escalation study will provide necessary information for a future definitive phase III clinical trial on the efficacy of treatment with HA in patients with SAH.
The study was designed to enroll 80 patients at 5 centers in the US. Patients with eligible SAH first underwent surgical or endovascular repair, which was considered standard care. Endovascular repair was a repair of the aneurysm from the inside of the blood vessel.
Following neurosurgical or endovascular treatment, participants were given a daily infusion of HA for 7 days. The HA dose was allocated as follows: the first tier (20 patients) would receive 0.625 grams (g) of HA per kilogram (kg) of body weight; patients in the second tier would receive 1.25g of HA per kg; patients in the third tier would receive 1.875g of HA per kg; and patients in the fourth tier would receive 2.5g of HA per kg. Safety and tolerability was evaluated by the Data and Safety Monitoring Board (DSMB) after each tier was completed and before the study advanced to the next dose tier. A specific safety threshold for congestive heart failure and other adverse events was defined based on data from previous studies.
In the follow-up phase, patients participated in study-related evaluations of their health at 15 days and three months. Duration of the study for participants was 90 days.

- Safety and Tolerability of the 25% Human Albumin Dosages and the Functional Outcome. [ Time Frame: 9 days after enrollment ]Tolerability outcome: Subject's ability to receive the full allocated human albumin dose without incurring frank congestive heart failure or experiencing anaphylactic reactions that required discontinuation of the treatment. Study would be terminated if 2 or more subjects developed severe or life-threatening heart failure considered to be related (probably, possibly, and definitely) to albumin treatment.
- Serious Adverse Events [ Time Frame: within 3 months after enrollment ]
Serious adverse events included neurological and medical complications and neurological deterioration.
Neurological deterioration was defined as a decline by more than 2 points in the Glasgow Coma Scale.
- Good Clinical Outcome Was Defined as a Glasgow Outcome Scale Score of 0-1 [ Time Frame: 3 months after enrollment ]Number of subjects with good clinical outcome defined as a Glasgw Outcome Scale score of 0-1

| Ages Eligible for Study: | 18 Years to 79 Years (Adult, Older Adult) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Patients (male or female) were at least 18 but younger than 80 years of age.
- Onset of new neurological signs of subarachnoid hemorrhage within 72 hours at the time of evaluation and initiation of treatment with 25% human albumin.
- Clinical signs consistent with the diagnosis of subarachnoid hemorrhage including severe thunderclap headache, cranial nerve abnormalities, decreased level of consciousness, meningismus and focal neurological deficits.
- Computed tomography demonstrated subarachnoid hemorrhage.
- Cerebral angiography revealed the presence of saccular aneurysm(s) in a location that explains the subarachnoid hemorrhage.
- Treatment of cerebral aneurysm was carried out prior to initiation of HA infusion but within 72 hours of symptom onset. Accepted treatments of aneurysms include surgical clipping or endovascular embolization.
Exclusion Criteria:
