Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Non-severe recent stroke (within 30 days) attributed to 70-99% stenosis of intracranial artery (internal carotid, middle cerebral, vertebral, basilar); must be confirmed by CTA (or DSA if already available) for enrollment into the trial

Hemodynamic compromise based on borderzone infarct pattern* for the anterior circulation (internal carotid and middle cerebral artery stenosis) and by low flow state on QMRA** for the posterior circulation (vertebral and basilar artery stenosis)

Must not have

Indication for warfarin or NOAC beyond enrollment (e.g. venous thrombo-embolism, atrial fibrillation)

Any neurological disease which would confound follow-up assessment

Timeline

Screening 3 weeks

Treatment Varies

Follow Up 1 year

Summary

This trial will study whether a minimally-invasive endovascular intervention can be performed safely in patients with a high risk of stroke due to atherosclerosis, as well as its effect on stroke risk.

Who is the study for?

This trial is for people aged 30-90 with a recent, non-severe stroke due to 70-99% blockage in certain brain arteries. They must have specific risk factors or diseases in other blood vessels if they're under 50. Exclusions include major strokes, conditions that could affect the study's results, very short life expectancy, certain heart and blood disorders, and previous treatments on the target area.

What is being tested?

The trial tests submaximal balloon angioplasty's safety and effectiveness for treating intracranial atherosclerotic stenosis (ICAS), which can lead to strokes. It aims to support future larger trials by providing initial data on this technique as an alternative when medical therapy isn't enough.

What are the potential side effects?

While not explicitly listed here, potential side effects may include risks associated with angioplasty such as bleeding at the catheter insertion site, damage to blood vessels from the balloon or catheter, infection risk from invasive procedures and possible allergic reactions to materials used.
