Background and study aims
A spontaneous subarachnoid haemorrhage (SAH) is a serious medical condition caused by sudden bleeding over the surface of the brain. It is most often caused when a bulge in a blood vessel wall (brain aneurysm) bursts (ruptures) because the vessel wall has become weakened over time. Following rupture blood pools inside the skull (which cannot expand due to its rigid structure) leading to pressure on the brain and starving it of oxygen (cerebral ischaemia) causing further brain damage. To treat this, a hole is usually drilled into the skull and a tube (external ventricular drain) is placed inside so that the collected blood can escape, lowering pressure on the brain. When a person sustains a severe injury chemicals are released in the body to help start the healing process, such as the protein Interleukin−1 (IL−1) which triggers inflammation (swelling). Studies have shown that IL-1 actually contributes to the damage caused cerebral ischaemia. Kineret® is a drug which acts by blocking the action of IL-1. The aim of this study is to find out whether Kineret® can change the concentration of the inflammatory biomarkers (natural chemical indictors of inflammation) in the blood and cerebral spinal fluid (fluid that cushions the brain).
Who can participate?
Patients aged 16 years or over who have had a spontaneous subarachnoid haemorrhage (SAH) and have had an external ventricular drain (EVD) fitted.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group are a bolus (one-off large dose) injection of 500mg Kineret® into a vein (IV) over 1 minute. Immediately afterwards, the participants are started on a drip (infusion) of Kineret® which is given slowly, over 24 hours. Those in the second group are given a blous injection of a placebo (dummy) over one minute, followed by an infusion of saline (salt water) and placebo (dummy) over 24 hours. Participants in both groups have samples of blood and cerebral spinal fluid (CFS) taken at the start of the study and then after 6, 12, 24, 36, 48 and 72 hours in order to measure the concentration of the chemical indicators of inflammation (inflammatory biomarkers).

| Scientific title | The effect of Kineret® on brain biomarkers in patients with subarachnoid haemorrhage: Double-blind randomised placebo-controlled trial |
| Study objectives | The presence of Kineret® in the cerebrospinal fluid (CSF) at concentrations that have been shown to be experimentally therapeutic decrease concentrations of inflammatory biomarkers in the CNS. |
| Ethics approval(s) | Added 05/06/2009: Wales REC approved on the 29th January 2009 (ref: 09/MRE09/1) |
| Health condition(s) or problem(s) studied | Subarachnoid haemorrhage |
| Intervention | The study is a double-blind randomised controlled trial of Kineret® with participants with an external ventricular drain (EVD) inserted as part of their clinical care. Participants will be randomised to receive a regime of 500 mg bolus dose plus a 10 mg/kg/h intravenous infusion for 24 hours of Kineret® or placebo, which has been identified from a previous pharmacokinetic dose-finding study. Blood and CSF will be taken immediately prior to bolus dose of IMP/placebo (baseline); and at 6, 12 and 24 hours (during period of infusion) and then at 36, 48 and 72 hours (from time of bolus injection). A final sample will be obtained at Day 7 (study end) if the participant still has an EVD in-situ. Analysis of these samples will show the effect of Kineret® on inflammatory markers and allow the concentration of the markers to be measured. |
| Intervention type | Drug |
| Pharmaceutical study type(s) | |
| Phase | Phase IV |
| Drug / device / biological / vaccine name(s) | Interleukin-1 (IL-1), (Kineret®) |
| Primary outcome measure | To determine whether intravenously administered Kineret® causes a decrease in the concentration of central inflammatory biomarkers in the blood and CSF samples following SAH compared to placebo. The following markers will be assessed: C-reactive protein (CRP), IL-1RA, IL-1a, IL-1ß, IL-6, IL-8, IL-10 Blood and CSF samples will be taken immediately prior to bolus dose of IMP/placebo (baseline); and at 6, 12 and 24 hours (during period of infusion) and then at 36, 48 and 72 hours (from time of bolus injection). A final sample will be obtained at Day 7 (study end) if the participant still has an EVD in-situ. |
