Statins and Cerebral Blood Flow in Subarachnoid Hemorrhage (SAH)
This study is currently recruiting participants.
Verified by Washington University School of Medicine, November 2008
Sponsored by: Washington University School of Medicine
Information provided by: Washington University School of Medicine
ClinicalTrials.gov Identifier: NCT00795288
  Purpose

The primary objective of this project is to investigate the effect of statin therapy on cerebral blood flow in patients with aneurysmal SAH who are randomized to receive or not receive statins in a blinded design.


Condition Intervention Phase
Subarachnoid Hemorrhage
Drug: Simvastatin, 80 mg/day for 21 days
Drug: placebo
Phase I
Phase II

MedlinePlus related topics: Statins
Drug Information available for: Simvastatin
U.S. FDA Resources
Study Type: Interventional
Study Design: Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Placebo Control, Parallel Assignment, Efficacy Study
Official Title: Effect of Statins on Cerebral Blood Flow After Subarachnoid Hemorrhage

Further study details as provided by Washington University School of Medicine:

Primary Outcome Measures:
  • Resting cerebral blood flow during peak period of vasospasm risk [ Time Frame: 7-10 days after hemorrhage ] [ Designated as safety issue: No ]
  • Cerebral autoregulation during peak period of vasospasm risk [ Time Frame: 7-10 days after hemorrhage ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Impact of statin on oxygen extraction fraction and cerebral metabolism during peak period of vasospasm risk [ Time Frame: 7-10 days after hemorrhage ] [ Designated as safety issue: No ]

Estimated Enrollment: 60
Study Start Date: August 2008
Estimated Study Completion Date: March 2013
Estimated Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
1: Experimental
Simvastatin, 80 mg/day
Drug: Simvastatin, 80 mg/day for 21 days
Active treatment group
2: Placebo Comparator Drug: placebo
Control group

Detailed Description:

We will determine if statin therapy improves CBF in patients with aneurysmal subarachnoid hemorrhage. This improvement, if present, may be due to improved basal CBF, improved autoregulatory function, or a mitigation of large arterial narrowing. The information gain from this study will help us to better understand the mechanism of action of statins. This knowledge may be useful in the design of future studies with statins and in the development of other therapies aimed at similar mechanisms.
