E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Aneurysmal subarachnoid hemorrhage (aSAH) |
|
E.1.1.1 | Medical condition in easily understood language |
Subarachnoid hemorrhage is bleeding in the space between your brain
and surrounding membrane. Bleeding results from the rupture of an
abnormal bulge in a blood vessel in your brain (brain aneurysm). |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Nervous System Diseases [C10] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | Yes |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the efficacy of intraventricular EG-1962 to standard of care
oral nimodipine in subjects with aSAH |
|
E.2.2 | Secondary objectives of the trial |
To determine the safety of intraventricular EG-1962 compared to
standard of care oral nimodipine in subjects with aSAH |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male or female between the ages of 18 to 75 years, inclusive
2. Ruptured saccular aneurysm confirmed by angiography (CTA, MRA or
catheter) and repaired
by neurosurgical clipping or endovascular coiling
3. Subarachnoid hemorrhage on CT scan (pre-repair) of grade 2-4 on the
modified Fisher scale
(diffuse [clot present in both hemispheres] thick or thin, or local thick)
4. External ventricular drain in place
5. WFNS grade 2, 3, or 4 assessed during the Pre-randomization Phase
after repair of the
aneurysm but prior to randomization
6. The subject must be able to receive intraventricular IP within 48
hours after the onset of aSAH and within 4 hours after the start time of
intraventricular IP suspension in the pharmacy. Onset of aSAH is defined
as the time the subject experiences the first symptom of aSAH (e.g.,
severe headache or loss of consciousness reported either by the subject
or by a witness). If found unconscious, the onset of SAH is defined as
the time the subject was last known normal
7. Female subjects of child-bearing potential must have a negative
pregnancy test (urine or serum) during the Pre-randomization Phase and
must agree to use adequate birth control for at least 30 days following
the end of the Treatment Period. Male subjects must agree to use
adequate birth for at least 30 days after the end of the Treatment Period
8. Signed informed consent from the subject or the subject's legal
representative after the
completion of aneurysm repair but prior to any study-specific procedures
being performed
9. Able and willing to comply with follow up visit schedule
|
|
E.4 | Principal exclusion criteria |
1. Major complication during aneurysm repair such as, but not limited to,
massive intraoperative hemorrhage, brain swelling, arterial occlusion, or
inability to secure the ruptured aneurysm
2. Angiographic vasospasm prior to randomization
3. Clinical or radiological evidence of a cerebral infarction with
neurological deficit
4. Increased intracranial (ICP) pressure >30 mm Hg lasting >4 hours
anytime during the Prerandomization Phase
5. Substantial intraventricular hemorrhage
6. Aneurysm repair requiring flow diverting stent or stent-assisted
coiling and dual antiplatelet
therapy
7. Subject is expected to undergo repair of additional aneurysms within
90 days in cases where
multiple aneurysms were identified during the Pre-randomization
PhaseHemodynamically unstable during the Pre-randomization Phase
(i.e., systolic blood pressure (SBP) <100 mm Hg, requiring >6 L colloid,
or crystalloid fluid resuscitation)
9. Cardiopulmonary resuscitation was required during the Prerandomization
Phase
10. Symptoms or electrocardiogram (ECG) signs of acute myocardial
infarction or unstable angina pectoris prior to randomization
11. Electrocardiogram evidence and/or physical findings compatible with
second or third degree heart block or of cardiac arrhythmia associated
with hemodynamic instability
12. Echocardiogram, if performed as part of standard of care before
randomization, revealing a left ventricular ejection fraction <40%
13. Severe or unstable concomitant condition or disease (e.g., known
significant neurologic deficit, cancer, hematologic or coronary disease),
or chronic condition (e.g., liver disease, kidney disease or psychiatric
disorder), that, in the opinion of the investigator, may increase the risk
associated with study participation or IP administration, or may
interfere with the interpretation of study results
14. Subjects who have received an investigational product or
participated in another interventional clinical study within 30 days prior
to randomization. Subjects participating in a
non-interventional study that has no bearing on assessment of EG-1962
or enteral nimodipine
may be enrolled per guidelines of the local Institutional Review Board
(IRB)/Independent
Ethics Committee (IEC)
15. Known hypersensitivity to nimodipine or other dihydropyridine
calcium channel antagonists, poly-D, L-lactide-co-glycolide (PLGA), or
hyaluronic acid |
