E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the safety of up to 28 days of SFX-01 dosed at up to 600mg (92mg Sulforaphane) per day.
To detect the presence of SFN in Cerebrospinal Fluid (CSF).
To determine if a minimum of 7 days treatment with SFX-01 reduces Middle Cerebral Artery (MCA) peak flow velocity following subarachnoid haemorrhage (SAH). |
|
E.2.2 | Secondary objectives of the trial |
To determine if a minimum of 7 days treatment with SFX-01 improves clinical outcome following SAH as measured using the modified Rankin Scale assessed at 7 days, discharge, 28, 90 and 180 days post ictus.
To determine blood SFN levels (and its metabolites) with treatment with SFX-01 (300mg bid).
To determine CSF SFN levels and kinetics with treatment with SFX-01 (300mg bid).
To determine if up to 28 days treatment with SFX-01 increases blood haptoglobin (HP) levels and decreases malondialdehyde (MDA) levels following SAH.
To determine if up to 28 days treatment with SFX-01 can reduce the incidence of Delayed Cerebral Ischaemia (DCI) following SAH.
To determine if up to 28 days treatment with SFX-01 improves long-term outcome in subjects following SAH.
To determine if up to 28 days of treatment with SFX-01 can reduce iron deposition and cortical atrophy following SAH. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Pharmacokinetic sub-study
A group of up to 12 patients, all of whom have been fitted with an EVD as part of their normal treatment, will be selected for a pharmacokinetic sub-study. Additional patient consent will be required for the sub-study;
The patients will, in addition to all other procedures (with the exception of lumbar puncture), undergo serial CSF sampling (1 sample pre dose and hourly for 6 hours post dose) at first dose and day 7. If the EVD is fitted after first dose, serial sampling will only take place at day 7. |

E.3 | Principal inclusion criteria |
1. Patients with radiological evidence of spontaneous aneurysmal SAH
2. Fisher grade 3 or 4 on CT
3. Definitive treatment of aneurysm has not been ruled out
4. Previously living independently
5. In the opinion of the investigator, the delay from ictus to randomisation and initiation of trial medication will not exceed 48 hours
6. Aged 18 to 80 years
7. In the opinion of the investigator it will be possible to obtain Informed Consent from the Patient, Personal Legal Representative or Professional Legal representative within 24 hours of first dose |
|
E.4 | Principal exclusion criteria |
1 Traumatic SAH
2 Fisher grade 1 or 2
3 SAH diagnosed on lumbar puncture with no evidence of blood on CT
4 Decision not to treat aneurysm has been made
5 Plan to withdraw treatment

7 Liver disease as defined as total bilirubin greater than 2-fold the upper limit of normal as measured by the local laboratory
8 Females who are pregnant or lactating.
9 Participants enrolled in another interventional research trial in the last 30 days
10 Patients for whom it is known, at the time of screening, that clinical follow-up will not be feasible
11 Patients unwilling to use two forms of contraception (one of which being a barrier method) 30 days for men and 90 days for women after last IMP dose
12 Known hypersensitivity to any component of a sulforaphane containing product including broccoli |
