Augmenting Cerebral Blood Flow to Preserve the Penumbra Trial

Status Recruiting

Clinical Trial Summary

The primary objective of the study is to demonstrate that SPG (Sphenopalatine Ganglion) stimulation started within 6 hours from stroke onset slows the expansion of the infarct core volume in acute ischemic stroke.

Clinical Trial Description

The goal of this study is to identify Acute Ischemic Stroke patients who have a potentially salvageable penumbra and to test if 6 hours of SPG (Sphenopalatine Ganglion) stimulation may "freeze" the volume of the penumbra and reduce the extent of tissue death.

Following a minimally-invasive implantation of the ISS injectable implant, patients will be randomized to either the Treated or Control arm in a 1:1 ratio. Randomization will be dynamic according to the patient's baseline covariates of core volume, total volume, Hypoperfusion Intensity Ratio (HIR), time to baseline imaging, age, NIHSS. Patients in the Treated arm will be treated with active SPG stimulation while patients in the Control arm will undergo sham treatment. After treatment/sham treatment, patients in both groups will undergo a follow up brain non-contrast CT, CT perfusion and CT angiography imaging, 6:45hrs±15min after baseline CTP initiation.

In the case the patient is cooperative, hand strength (pinch and grasp) evaluations should be assessed before and during the 1st treatment/ sham SPG stimulation session.

Following the assessment of the penumbra (after 6 hours) patients will be treated or sham treated for 5 additional consecutive sessions (4 hours each), the first starting within 18-24 hours from stroke onset and the others 18-26 hours from previous treatment initiation and will be followed for 90 days to assess their clinical outcome. In one session (preferably at day 2) Common Carotid Doppler examination is performed to evaluate blood flow dynamics before and during the treatment/sham session.

After the last treatment session, the implant is removed. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
