Plain English summary of protocol
Background and study aims.
A blood vessel abnormality called an aneurysm can cause a bleed within the head. We wish to study the potential benefits of giving a standard cholesterol lowering drug (called Simvastatin) after a bleed has occurred. This is a licensed medication used regularly in the treatment for other vascular conditions including heart attacks and strokes, but it is not licensed at this stage for the treatment of a bleed in the brain. In some instances we may also wish to find out whether the patients genetic makeup can influence the course of your disease, its clinical outcome, or response to the medicine that we are testing.
Who can participate?
Patients aged 18 65years in whom the admitting neurosurgeon has diagnosed a bleed onto the surface of the brain, called a subarachnoid haemorrhage (SAH). We propose to recruit approximately 800 people to the trial.
What does the study involve?
Patients will be allocated randomly (like a flip of the coin) to taking either Simvastatin 40mg or an inactive dummy drug called a placebo. The treatment will be administered as one tablet daily for up to 21 days. If the patient is discharged from the Neurosurgical Unit before 21 days, treatment will be stopped. Nobody (not even the doctors) will know which treatment is being given until the study is over. However, if necessary, the doctor will be able to find out which treatment has been given if any concern arises. Before they leave the hospital we will assess the patients level of recovery. Two short questionnaires will be sent to their home 6 months later asking about their current level of recovery and state of health.
What are the possible benefits and risks of participating?
In the event of taking Simvastatin we hope that this drug might help in recovery. However, this cannot be guaranteed. More likely, the information we obtain from this study may help us to improve on the treatment for future patients suffering from SAH.
Possible rare side effects of Simvastatin include muscle weakness or tenderness, headache, nausea or rash. However no regular side effects have been observed even in patients receiving this treatment for many years. However, in the event of any serious unforeseen reactions, or if any concerns arise, the drug will be stopped immediately.

---|---|
Age group | Adult |
Lower age limit | 18 Years |
Upper age limit | 65 Years |
Sex | Both |
Target number of participants | 800 |
Key inclusion criteria | 1. Patients aged 18-65 years 2. If the admitting neurosurgeon has a high index of suspicion of a spontaneous aneurysmal subarachnoid haemorrhage (good clinical history with convincing computerised tomography [CT] findings) 3. Any clinical grade accepted provided there is a reasonable prospect of survival 4. Delay to randomisation and initiation of trial medication, from the time of the presenting bleed, does not exceed 96 hours 5. Independent prior to the SAH |
Key exclusion criteria | 1. Unsalvageable patients: fixed and dilated pupils after resuscitation, and/or a devastating scan, which precludes definitive therapy 2. Already taking statin therapy 3. Those taking warfarin-type drugs 4. Pregnancy 5. Known renal or hepatic impairment 6. Suspected or known additional disease process, which threatens life expectancy (e.g. malignancy) 7. Known or strong suspicion of drug abuse, alcoholism, or those who are unlikely to be amenable to six-month follow up |
