This is a randomized, double-blind, placebo-controlled, single-dose study investigating the safety and efficacy of NA-1 in patients with subarachnoid hemorrhage (SAH) undergoing endovascular repair of ruptured intracranial aneurysms. Up to 300 male and female patients with SAH undergoing endovascular repair of a ruptured intracranial aneurysm will be dosed with 2.60 mg/kg of NA-1 or placebo as a 10 minute intravenous infusion after completion of the endovascular procedure on Day 1 of the study period. Subjects will undergo interim procedures at Day 2-4, Day 30-45, and end-of-study procedures on Day 90.

Primary Outcome Measures:
  • Modified Rankin Scale (mRS) [ Time Frame: 90 days ] [ Designated as safety issue: No ]
    Proportion of subjects achieving independent functioning as defined as a score of 0-1 on the mRS at Day 90.

Secondary Outcome Measures:
  • Modified Rankin Scale (mRS) [ Time Frame: 30-45 days ] [ Designated as safety issue: No ]
    Proportion of subjects achieving a good outcome as defined as a score of 0-1 on the mRS at Day 30-45.

  • National Institutes of Health Stroke Scale (NIHSS) [ Time Frame: 90 days ] [ Designated as safety issue: No ]
    Proportion of subjects achieving a good outcome as defined as a score of 0-1 on the NIHSS at Day 90.

  • Mortality [ Time Frame: 90 days ] [ Designated as safety issue: No ]
    Rate of subarachnoid hemorrhage related mortality over the 90 day study period.

  • In-hospital length of stay [ Time Frame: 90 days ] [ Designated as safety issue: No ]
    Duration of in-hospital length of stay.

Arms Assigned Interventions
Experimental: NA-1
20 amino acid peptide that consists of a 9 amino acid domain that inhibits PSD-95 and an 11 amino acid domain that enables the peptide to cross the blood-brain barrier. Single intravenous dose of 2.6 mg/kg of NA-1 administered as a 10-minute infusion.
Drug: NA-1
Placebo Comparator: Placebo
Single intravenous dose of 2.6 mg/kg of placebo administered as a 10-minute infusion.
Drug: Placebo


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • 1. A diagnosis of a ruptured brain aneurysm deemed suitable for repair by neuroendovascular techniques involving intraluminal occlusion by detachable platinum coils, or any neuroendovascular technique such as balloon-assisted coiling not requiring the use of antiplatelet agents other than ASA.
  • 2. Patient should be Grade I-IV on the WFNS grading scale for SAH.
  • 3. Male or female with a minimum age of 18 years on the day of enrolment.
  • 4. Female subjects of childbearing potential: Negative pregnancy test.
  • 5. Non-surgically sterile males or males with partners of childbearing potential must be willing to use condoms with spermicide for 3 months after completion of dosing.
  • 6. Body weight less than or equal to 180 kg.
  • 7. Vital signs on admission:

    • Blood pressure between 80-180 mm Hg systolic/50-100 mm Hg diastolic;
    • Body temperature ≤ 38.5oC.
  • 8. Informed consent and availability of the subject for the entire study period and willingness of the subject to adhere to protocol requirements.

Exclusion Criteria:

  • 1. Prior SAH within 6 months of presentation.
  • 2. Dissecting or mycotic brain aneurysm.
  • 3. Planned endovascular vessel sacrifice as the primary modality for aneurysm treatment.
  • 4. Intended use of antiplatelet medications other than ASA for the endovascular repair procedure.
  • 5. Known history of life-threatening allergic reaction to any medication.
  • 6. Chronic renal disease defined as a baseline serum creatinine > 150 µmol/L.
  • 7. Women who are pregnant, or have a positive urine or blood (β-hCG) pregnancy test.
  • 8. Women who are breastfeeding.
  • 9. Any clinically significant psychiatric or psychological disease, which would preclude the patient from completing the protocol.
  • 10. Pre-morbid (estimated) modified Rankin scale score of >1.
  • 11. Previous major stroke.
  • 12. Patients with known HIV infection.
  • 13. Participation in a clinical trial with an investigational drug within 30 days preceding this study.
  • 14. Previous participation in the ENACT trial (e.g, to treat a prior aneurysm), participation in another trial involving NA-1 or prior receipt of NA-1.
  • 15. Any other medical condition that the site investigator deems would put the patient at excessive risk of participation in the study or an expected life expectancy less than 1 year or that would result in inability to collect clinical outcomes at 90 days.
