Brief Summary:
This study is a non-randomized, Phase 2 clinical trial designed to measure the cerebral blood flow (CBF) response to inhaled nitric oxide in acute ischemic stroke patients and healthy subjects. The monitoring is a 35 minute session during which cerebral hemodynamics will be monitored with both diffuse correlation spectroscopy (DCS) and transcranial doppler ultrasonography (TCD) while blood pressure, heart rate, cardiac output, respiratory rate, end oxygen saturation, and inhaled nitric oxide (NO)/nitrogen dioxide (NO2) concentration, are continuously monitored.

Arm Intervention/treatment
Experimental: Healthy Controls
The protocol will be a 35-minute monitoring session, during which cerebral hemodynamics will be monitored with both DCS and TCD, while blood pressure, heart rate, cardiac output, respiratory rate, end oxygen saturation, and inhaled nitric oxide concentration, are continuously monitored. 5 minutes of baseline hemodynamics will be assessed, after which the subject will breath iNO for 5 minutes, followed by 5 minutes of room air. This iNO/room air cycle will be repeated with a total of 3 different iNO concentrations. The full protocol will require 35 minutes. Subjects will be called at 24 hours after the monitoring session to determine any tolerability issues or adverse events.
 Drug: Nitric Oxide
Inhaled Nitric Oxide gas
Other Names:
  • iNO
  • NO2
Experimental: Acute Ischemic Stroke
Patients will be enrolled in the study within 72 hours of stroke symptom onset. The protocol will be a 35-minute monitoring session, during which cerebral hemodynamics will be monitored with both DCS and TCD, while blood pressure, heart rate, cardiac output, respiratory rate, end oxygen saturation, and inhaled nitric oxide concentration, are continuously monitored. 5 minutes of baseline hemodynamics will be assessed, after which the subject will breath iNO for 5 minutes, followed by 5 minutes of room air. This iNO/room air cycle will be repeated with a total of 3 different iNO concentrations. The full protocol will require 35 minutes. Subjects will be undergo a final assessment at 24 hours after the monitoring session to determine any tolerability issues or adverse events.
 Drug: Nitric Oxide
Inhaled Nitric Oxide gas
Other Names:
  • iNO
  • NO2


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change in cerebral blood flow during the administration of iNO [ Time Frame: Conclusion of the 35 minute protocol ]

Secondary Outcome Measures :
  1. Change in blood flow velocity as measured by TCD during iNO administration [ Time Frame: Conclusion of the 35 minute protocol ]
  2. Change in mean arterial blood pressure (MAP) during iNO administration [ Time Frame: Conclusion of the 35 minute protocol ]
  3. Time to maximum CBF effect after the introduction of iNO [ Time Frame: Conclusion of the 35 minute protocol ]
  4. Duration of residual effect after cessation of iNO (time to return to baseline) [ Time Frame: Conclusion of the 35 minute protocol ]
