Outcome Measures
Primary Outcomes (1)
Global Disability Level on the Modified Rankin Score (mRS)
Modified Rankin Scale (mRS) is a measure of global disability. Total scale range is 0-6, with lower values indicating better outcomes. 0 = No symptoms at all 1. = No significant disability despite symptoms; able to carry out all usual duties and activities 2. = Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance 3. = Moderate disability; requiring some help, but able to walk without assistance 4. = Moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance 5. = Severe disability; bedridden, incontinent and requiring constant nursing care and attention 6. = Dead
90 days
Study Arms (2)
Trans Sodium Crocetinate
EXPERIMENTALTrans sodium crocetinate (TSC) will be administered intravenously as a bolus to subjects randomized to experimental drug. The bolus dose will consist of 0.25 mg/kg of TSC based on the estimated subject weight.
Placebo
PLACEBO COMPARATORThe placebo consists of commercially available sterile saline. Placebo will be administered intravenously as a bolus to subjects randomized to placebo. The volume of sterile saline will be based on the estimated subject weight.
Interventions
In the study drug kit containing the experimental drug (TSC), TSC will be reconstituted with the Sterile Water for Injection (USP) supplied in the same kit. There will be an unblinded paramedic who will reconstitute and inject the TSC on the ambulance.
The study drug kit containing placebo (sterile saline for Injection) will be prepared and injected by the unblinded paramedic on the ambulance.
Eligibility Criteria
You may qualify if:
- Age 40-85, inclusive
- Last known well time 15-120 minutes before anticipated study drug injection
- Suspected stroke identified by the LAPSS
- Moderate to severe motor deficit, with Los Angeles Motor Scale (LAMS) 2 or higher
- No seizure
You may not qualify if:
- Coma
- Rapidly improving neurologic deficit
- History of seizures or epilepsy
- Pre-existing neurologic, psychiatric, or advanced systemic disease that would confound the neurological or functional outcome evaluations
- SBP \< 90 or \> 220
- Major head trauma in the last 24 hours
- Recent stroke within 30 days
- Known to be pregnant or lactating

Limitations and Caveats
The trial was early terminated after 6 subjects were enrolled due to logistical issues surrounding the COVID-19 pandemic. Due to this low enrollment number, the statistical plan outlined in the protocol was not utilized. Data listings and tables were instead created, which captured data on the 6 subjects in a descriptive manner. Therefore, no substantive conclusions could be drawn.
