Simvastatin in Aneurysmal Subarachnoid Haemorrhage (STASH) a Multicentre Randomised Controlled Clinical Trial

Completed · Phase 3 · Has a placebo group

Conditions studied: Subarachnoid Haemorrhage

In brief

Intracranial bleeding from ruptured blood vessels (called a subarachnoid haemorrhage -SAH) affects 7000 patients each year in the UK and is a source of considerable death and disability, even in young adults. Recent observations indicate that these bleeds can cause reduced cerebral blood flow which leads to a bad outcome. High rates of death and disability occur, and are particularly prevalent when low cerebral blood flow results in stroke. Prevention of cerebral artery spasm and improvement in blood vessel reflexes are the target of modern therapy. Candidate drugs include statins which have an impeccable safety record and multiple potential beneficial actions (improve cerebral blood flow, reduce inflammatory processes, reduce adverse blood coagulation) following SAH. The investigators plan to use a statin, Simvastatin (40 mg) to improve cerebral blood flow and reduce inflammation. We have already completed a phase 11 study (n=80) which demonstrated potential benefits for acute statin therapy following SAH, and the investigators now wish to conduct a multi-centre phase 111 study to explore any potential clinical benefits in a larger population (n=1600). The purpose is to see whether the positive effects of statins seen in our phase II study translate into clinical benefits - both short term (e.g. reduced need for intensive care) and long term (outcome and wellbeing at 6 months).

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients (age 18 - 65 yr) in which the admitting neurosurgeon has confirmatory evidence of an aneurysm, either by CT angiography, MR angiography or DSA.
• Any clinical grade accepted provided a reasonable prospect of survival.
• Delay to randomisation and initiation of trial medication from the time of the presenting ictus does not exceed 96 hours.

You may not qualify if…

• Unsalvageable patients:Fixed and dilated pupils after resuscitation, and/or a devastating scan, which precludes definitive therapy.

• Those taking Warfarin - type drugs.
• Pregnancy.
• Known renal or hepatic impairment
• Suspected or known additional disease process, which threatens life expectancy (e.g.malignancy).
• Known or strong suspicion of drug abuse, alcoholism, or those who are unlikely to be amenable to 6 month follow up.
