Summary
A Phase II, randomized, blinded, placebo-controlled, parallel group study with patients experiencing a large vessel occlusion acute ischemic stroke who are selected for endovascular revascularization. Participants will be given a 48 h infusion of either 0.5 mL/kg/h RNS60 (up to a maximum of 60 mL/h), 1 mL/kg/h RNS60 (up to a maximum of 120 mL/h), or 1 mL/kg/h (up to a maximum of 120 mL/h) placebo (normal saline) starting within 30 minutes of consent after confirmation of candidacy for endovascular thrombectomy.

Criteria
Inclusion Criteria:

1. Acute ischemic stroke (AIS) selected for emergency endovascular treatment.

2. Age 18 years or older.

3. Onset (last-known-well) time to randomization time within 24 hours.

4. Disabling stroke defined as a baseline National Institutes of Health Stroke Score
(NIHSS)

1. NIHSS > 5 for internal carotid artery (ICA) and M1-middle cerebral artery (MCA)
occlusion or

2. NIHSS > 10 for M2-MCA occlusion.

5. Confirmed symptomatic intracranial occlusion at one or more of the following
locations: Intracranial carotid I/T/L, M1 or M2 segment MCA. Tandem extracranial
carotid and intracranial occlusions are permitted.

6. Pre-stroke (24 hours prior to stroke onset) independent functional status in
activities of daily living with modified Barthel Index (BI) ≥ 95. Patient must be
living without requiring nursing care.

7. Qualifying imaging performed less than 2 hours prior to randomization.

8. Consent process completed as per applicable laws and regulation and the IRB
requirements.

Exclusion Criteria:

1. Evidence of a large core of established infarction defined as ASPECTS 0-4.

2. Evidence of absence of collateral circulation on qualifying imaging (Collateral score
of 0 or 1).

3. Any evidence of intracranial hemorrhage or mass lesion on the qualifying imaging.

4. Planned use of an endovascular device not having approval or clearance by the relevant
regulatory authority.

5. Endovascular thrombectomy procedure is completed as defined by the presence of
arterial access closure.

6. Clinical history, past imaging or clinical judgment suggesting that the intracranial
occlusion is chronic or there is suspected intracranial dissection such that there is
a predicted lack of success with endovascular intervention.

7. Estimated or known weight > 120 kg (264 lbs).

8. Known pregnant/lactating female.

9. Known prior myocardial infarction, or history of congestive heart failure (CHF).

10. Known renal impairment defined as requiring renal replacement therapy (hemo- or
peritoneal dialysis).

11. Inability to have MRI imaging (Non- MR compatible implants or any other foreseeable
reason, including claustrophobia)

12. Severe or fatal comorbid illness that will prevent improvement or follow up.

13. Inability to complete follow-up treatment to Day 90.

14. Participation in another clinical trial investigating a drug, medical device, or a
medical procedure in the 30 days preceding trial inclusion and throughout the duration
of the trial.

15. Seizure at onset.

16. Ischemic stroke within previous 30 days.

17. Baseline QTc > 450 ms.

18. Any other symptom that in the investigator's opinion may complicate or preclude the
subject from participating in this trial.
