Use of Simvastatin for the Prevention of Vasospasm in Aneurysmal Subarachnoid Hemorrhage - Full Text View

Sponsor:	University of Illinois
Information provided by:	University of Illinois
ClinicalTrials.gov Identifier:	NCT00487461

Purpose

The purpose of this study is to test whether treatment with a drug called Simvastatin prevents and improves outcome in patients who have Subarachnoid bleeding. Simvastatin is currently approved for the treatment of high cholesterol levels.

Primary Outcome Measures:

To measure outcome in patients diagnosed with aneurysmal subarachnoid hemorrhage (aSAH) treated with Simvastatin, by assessing neurological outcome by accessing Glasgow Outcome Score, Modified Rankin Scale, and Barthel Index Score at day 21 post aSAH [ Time Frame: 21 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To determine efficiency of Simvastatin in decreasing the incidence of clinical vasospasm in aSAH, and define the optimal dose of Simvastatin and to measure outcome at 6 months follow up [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Estimated Enrollment:	150
Study Start Date:	May 2007
Estimated Study Completion Date:	June 2009
Primary Completion Date:	February 2009 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Placebo Comparator: Control Group Placebo tablet	Drug: Placebo Placebo tablet
Experimental: Study Group #1 Simvastatin 40 mg	Drug: Simvastatin Comparing two doses of Simvastatin to placebo Other Name: Zocor
Experimental: Study Group #2 Simvastatin 80 mg	Drug: Simvastatin Comparing two doses of Simvastatin to placebo Other Name: Zocor

Detailed Description:

Aneurysmal Subarachnoid hemorrhage (bleeding on the surface of the brain) affects 10 per 100,000 population each year. For survivors of the initial hemorrhage, delayed narrowing of the blood vessels (vasospasm) and related delayed strokes are the most common serious complication. Narrowing of blood vessels affect 30% of patients with such bleeding. Despite maximum therapy, nearly 50% of patients with symptomatic vasospasm with develop stroke. Because cerebral vasospasm remains the leading cause of morbidity and mortality after aSAH, this critically important issue needs further studies.

One hundred and fifty patients will be randomized, 50 to each arm of the study. Patients enrolled in the study will be receive the drug (either Simvastatin 40 mg or Simvastatin 80 mg per mouth daily), while the control group will receive a sugar tablet. The treatment will be continued for a total of 21 days. The neurological abilities (Stroke Outcome measures, these are included with the application for your review) at day 21 post aSAH will be reviewed at time of discharge as well at 6 months of follow up.
