Title: A Randomised Trial to Establish the Effects of Early Intensive Blood Pressure Lowering on Death and Disability in Patients With Stroke Due to Acute Intracerebral Haemorrhage
Brief Summary: The purpose of the study is to determine whether lowering high blood pressure levels after the start of a stroke caused by bleeding in the brain (intracerebral haemorrhage) will reduce the chances of a person dying or surviving with a long term disability. The study will be undertaken in two phases: a vanguard phase in 400 patients, to plan for a main phase in 2000 patients.


Options:
A: Inclusion criteria for eligibility

1. Admission to one of the participating study centres.
2. Age 18 years or over.
3. SAH with an aneurysmatic bleeding pattern.

Exclusion criteria for eligibility

1. Evidence of DCI after the SAH, defined as any decrease in the level of consciousness or the development of new focal neurological deficits after the onset of the SAH that is not due to increasing hydrocephalus, rebleeding of the aneurysm, epileptic seizure, septic- or metabolic encephalopathy, unless symptoms of DCI started within 3 hours.
2. Co-existing severe head injury.
3. Perimesencephalic haemorrhage (perimesencephalic bleeding pattern and no aneurysm on CT-angiography).
4. A history of a ventricular cardiac rhythm disorder, necessitating medical treatment.
5. A history of a left ventricular heart failure, necessitating medical treatment.
6. Likely transfer to another hospital, not participating in the trial, soon after treatment for the aneurysm.
7. Moribund.
8. Pregnancy.

   And furthermore, in selected centres where the sub study with CT perfusion will be performed:
9. Known allergy for CT-contrast agents.
10. Renal failure, defined as a serum creatinine \> 150 µmol/l, because of the risk of contrast nephropathy.
11. Diabetes mellitus.

Inclusion criteria for trial participation

1. Informed consent to participate in the proposed trial when DCI will develop.
2. DCI based on a decrease of at least one point on the Glasgow Coma Scale sum score unless the decrease doesn't reflect DCI as evaluated by the treating physician, and/or the development of new focal neurological deficits, diagnosed by a neurologist, neurosurgeon or intensivist.

Exclusion criteria for trial participation:

1. Another cause for neurological deterioration including.
2. A symptomatic aneurysm not yet treated by coiling or clipping.
3. Severe hypertension, defined as a spontaneous MAP of 120 mmHg or more at the moment of evaluation for trial participation.
4. Any contraindication for induced hypertension (such as a cardiac complication necessitating medical treatment) as evaluated by the treating physician.

   And furthermore, in selected centres where the sub study with CT perfusion will be performed:
5. No CTP scan at time of neurological deterioration.
6. More than 3 CTP scans since admission.
B: Inclusion Criteria:

10. Chronic renal failure requiring dialysis
11. Suspected or confirmed pregnancy
12. Non English speaking

15. Refusal of consent
D: Inclusion Criteria:

1. Males and females aged 18 to 75 years (inclusive).
2. Patients with a ruptured saccular aneurysm, confirmed by angiography (digital subtraction angiography \[DSA\] or computed tomography angiography \[CTA\]), and which has been successfully secured by surgical clipping. The time of aneurysm rupture must be known or possible to estimate with a reasonable degree of certainty.
3. World Federation of Neurological Surgeons (WFNS) grade I-IV measured prior to the clipping procedure, and which does not worsen to grade V post-procedure (based on regular Glasgow Coma Scale \[GCS\])\*
4. Patients with any diffuse clot (long axis \> or = 20 mm, or any clot present across both hemispheres) on baseline CT scan.
5. Women of childbearing potential must have a negative serum pregnancy test and must use a reliable method of contraception during the 12 weeks following study drug discontinuation.
6. Written informed consent to participate in the study must be obtained from the patient or a legal representative prior to initiation of any study-mandated procedure and randomization.

   * Patients must be evaluable for WFNS grade prior to the clipping procedure. Patients who cannot be assessed for WFNS post-procedure due to a requirement for uninterrupted sedation (e.g., for high or unstable intracranial pressure \[ICP\]) may be included in the study provided that a CT scan is performed at 12 hours post-procedure, but prior to randomization, ruling out any large procedure-related infarct.

Exclusion Criteria:

1. Patients with subarachnoid hemorrhage (SAH) due to causes other than a saccular aneurysm (e.g., trauma or rupture of fusiform or mycotic aneurysms).
2. Patients with intraventricular or intracerebral blood, in the absence of subarachnoid blood, or with only a local clot.
3. Presence of cerebral vasospasm seen on angiography prior to the clipping procedure.
4. Patients who experienced a major complication during the clipping procedure, such as massive bleeding, major arterial occlusion, a large territorial cerebral infarct defined as involving \> 1/3 of a vascular territory, or a new major neurological deficit post-procedure (e.g., hemiplegia or aphasia lasting \> or = 12 hours post-aneurysm clipping).\*
5. Patients for whom study drug cannot be started within 56 hours after the aneurysm rupture.
6. Patients who have had their aneurysm secured by coiling only.
7. Patients for whom it is known, at the time of screening, that certain follow-up, protocol-mandated imaging assessments will not be feasible.
8. Patients with hypotension (systolic blood pressure (SBP)\< or = 90 mmHg) that is refractory to treatment.
9. Patients with aspiration pneumonia.
10. Patients with pulmonary edema or severe cardiac failure requiring inotropic support.
11. Any severe or unstable concomitant condition or disease (e.g., known significant neurological deficit, cancer, hematological, or coronary disease), or chronic condition (e.g., psychiatric disorder), which, in the opinion of the investigator, would affect the assessment of the safety or efficacy of the study drug.
12. Significant kidney and/or liver disease, as defined by plasma creatinine \> or = 2.5 mg/dL (221 micromol/l) and/or total bilirubin \> 3 mg/dL (51.3 micromol/l) measured at the local site laboratory.
13. Patients receiving i.v. nimodipine, i.v. nicardipine, or fasudil hydrochloride, must have these drugs discontinued at least 4 hours prior to initiation of the study treatment.
14. Patients receiving statins for less than 2 weeks prior to admission must have them discontinued prior to study drug initiation.
15. Patients receiving cyclosporin A or other calcineurin inhibitors (e.g., tacrolimus), or patients for whom it is known at the time of randomization that these medications will be started during the study drug infusion period.
16. Patients who have received an investigational product within 28 days prior to randomization or those who have already participated in the current study.
17. Patients unlikely to comply with the protocol (e.g., unable to return for follow-up visits).
18. Known hypersensitivity to other endothelin receptor antagonists.
19. Patients with current alcohol or drug abuse or dependence.

    * Further detail on exclusion criterion number 4:

      * "Large territorial infarct" refers to those infarcts detected during the clipping procedure or immediately post-procedure (i.e., CT performed for suspicion of cerebral infarct or other complication). This does not imply having to wait 24-48 hours post-procedure to perform the protocol-mandated CT scan in order to randomize a patient.
      * Evaluation for a new major neurological deficit post-procedure implies the reversal of sedation (or waiting for the patient to recover from sedation) and the performance of a GCS examination (verbal scores in intubated patients may be extrapolated from the eye-opening and motor scores using the values provided in the table included in Section 3.9.1.2.1 of the protocol). In the event of a new major neurological deficit that does not improve within 12 hours after the clipping procedure, the patient cannot be included in the study.
