SUSHI: Subarachnoid Hemorrhage and Soluble Epoxide Hydrolase Inhibition Trial
Study Details
Study Description
Brief Summary
Soluble epoxide hydrolase (sEH) is the metabolizing enzyme of epoxyeicosatrienoic acids (EETs), which may play a role in reducing neuroinflammation and regulating cerebral blood flow after subarachnoid hemorrhage (SAH). Hypotheses: Pharmacologic inhibition of the sEH enzyme is safe and will result in increased EETs availability in the blood and cerebrospinal fluid. This study is a double-blind, placebo-controlled, phase 1b randomized trial to evaluate the safety and efficacy of GSK2256294, a novel soluble epoxide hydrolase inhibitor in patients with aneurysmal SAH.

Detailed Description
Study Description: Soluble epoxide hydrolase (sEH) is the metabolizing enzyme of epoxyeicosatrienoic acids (EETs), which may play a role in reducing neuroinflammation and regulating cerebral blood flow after subarachnoid hemorrhage (SAH).
Hypothesis: Pharmacologic inhibition of the sEH enzyme is safe and will result in increased EETs availability at the neurovascular unit, and a measured increase in the EET/DHET ratio in the serum and cerebrospinal fluid. This study is a double-blind, placebo-controlled, phase 1b randomized trial to evaluate the safety and of GSK2256294, an inhibitor of soluble epoxide hydrolase, in patients with aneurysmal SAH.
Objectives:
Primary Objective:
Determine the safety of administration of GSK2256294 in patients with aneurysmal SAH.
Secondary Objective:
Determine the pharmacodynamic effect of administration of GSK2256294 in patients with aneurysmal SAH on reducing EETs metabolism and biomarkers of cerebrovascular inflammation and endothelial injury.
Tertiary Objective:
Provide preliminary estimates of clinical endpoints to inform the design of a larger trial
Endpoints:
Primary Endpoints:
Determination of safety
Secondary endpoints:
-
Study days 7 and 10 serum EET/DHET ratios
-
Study days 7 and 10 cerebrospinal fluid (CSF) EET/DHET ratios
-
Study days 7 and 10 serum EPOME/DPOME ratio
-
Neuroinflammatory and endothelial injury biomarker levels from the blood and CSF at day 7 and day 10.
Tertiary, exploratory endpoints:
Clinical outcomes associated with SAH including neurologic status, disposition, vital status and incidence of delayed cerebral ischemia.
20 subjects will be randomized. Patients age 18 or above with confirmed ruptured aneurysms will be approached to provide written informed consent
Phase: Phase 1B
Description of Sites/Facilities Enrolling Participants: The study will take place at Oregon Health & Science University Hospital, with enrollment of patients admitted to the OHSU NSICU, a part of a comprehensive stroke center certified by the American Heart Association and Joint Commission for Accreditation of Healthcare Organizations, with a catchment area including the state of Oregon, Southwest Washington and Northern California. Approximately 80-100 patients with aneurysmal SAH are admitted each year.
Description of Study Intervention: Twenty patients will be equally randomized to receive once daily either 10 mg dose of GSK2256294 or placebo enterally for a duration of 10 days.
Study Duration: 24 months
Participant Duration: 90 days

Outcome Measures
Primary Outcome Measures
- Participants With Adverse Events [90 days]
Summary tables and listings will be provided for all reported adverse events, defined as adverse events that start on or after the first administration of study drug. The reported adverse event term will be assigned a standardized preferred term. Adverse events will be summarized based on the number and percentage of patients experiencing the event. In the event a patient experiences repeat episodes of the same adverse event, then the event with the highest severity grade and strongest causal relationship to study treatment will be used for purposes of incidence tabulations. All deaths will be reported in a patient listing, which will include the primary cause of death and the number of days between the date of the last dose of study drug and death.
Secondary Outcome Measures
- Study Day 7 and Study Day 10 Serum and CSF EET/ Dihyroxyeicosatrienoic (DHET) Ratio, by Mass Spectroscopic Analysis (ng/mL) [10 days]
Day 7 and day 10 serum EET/DHET ratios will be measured by liquid chromatography and mass spectroscopy of collected blood samples. Day 7 and day 10 CSF EET/DHET ratios will be measured by liquid chromatography and mass spectroscopy of collected CSF samples.
- Study Day 7 and Study Day 10 Serum Epoxyoctadecenoic Acid (EPOME) to Dihydroxyoctadec-12-enoic Acid (DPOME) Ratio, by Mass Spectroscopic Analysis (ng/mL) [10 days]
Study day 7 and study day 10 serum epoxyoctadecenoic acid (EPOME) to dihydroxyoctadec-12-enoic acid (DPOME) ratio, will be measure by mass spectroscopic analysis of collected blood samples.
- Serum Biomarkers of Endothelial Injury From Blood Samples Obtained on Study Day 7 and Study Day 10 [10 days]
The following serum biomarkers will be obtained from collected blood samples by Luminex assay: e-selectin, p-selectin, Vascular cell adhesion marker (VCAM-1), Platelet endothelial cell adhesion marker (PECAM-1, CD31), intercellular adhesion molecule (ICAM-1).
- CSF Biomarkers of Neuroinflammation, From Blood Samples Obtained on Study Day 7 and Study Day 10 [10 days]
The following CSF biomarker will be obtained from collected CSF samples by Luminex assay: Tumor necrosis factor alpha (TNF-α) (pg/mL), Interleukin 1β (IL-1β) (pg/mL), Interferon gamma (IFN-γ) (pg/mL), Interleukin 6 (IL-6) (pg/mL), Interleukin 8 (IL-8) (pg/mL), Monocyte chemoattractant protein 1 (MCP-1) (pg/mL)
Other Outcome Measures
- Hospital Length of Stay in Days [90 days]
The hospital length of stay will be recorded in days, at the time of hospital discharge.
- Discharge Disposition [90 days]
The disposition from the hospital in one of the following categories: home, home with services, rehab, long term acute care facility, skilled nursing facility, hospice, death
- Number of Participants With New Stroke on Hospital Discharge Imaging [90 days]
The last head CT or other brain imaging to detect the presence of a new area of cerebral infarction will be reviewed at the time of hospital discharge. A cerebral infarction will be defined as a one identified on hospital discharge that was not present on imaging between 24-48 hours after aneurysm occlusion, and not attributable to other causes such as surgical clipping or endovascular treatment. Hypodensities resulting from extraventricular drains or residual intraparencyhmal hematomas will not be considered new strokes.
- Modified Rankin Scale (mRS) at Hospital Discharge and 90 Day Follow up [90 days]
The mRS score will be determined by patient or surrogate interview, at both hospital discharge and 90 day follow up. Scores will be assigned based on the following: 0 - no symptoms, 1 - no significant disability, able to carry out all usual activities despite some symptoms, 2 - slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities, 3 - moderate disability, requires some help, but able to walk unassisted, 4 - moderately severe disability, unable to attend to own bodily needs without assistance, and unable to walk unassisted, 5 - severe disability, requires constant nursing care and attention, bedridden, incontinent, 6 - deceased.
- Extended Glasgow Outcome Scale (GOSE) Score at 90 Day Follow up [90 days]
At 90 day follow up, the GOSE will be determined by patient or surrogate telephone interview, based on a structured interview of 19 questions. The GOSE is a scale of 1-8 where 1 - deceased, 2 - vegetative state, 3 - low severe disability, 4 - upper severe disability, 5 - low moderate disability, 6 -upper moderate disability, 7 - low good recovery, 8 - upper good recovery.
