Intracranial Artery Stenosis clinical trials

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.

Balloon Angioplasty for Symptomatic Intracranial Artery Stenosis

BASIS

Start date: October 17, 2018
Phase: N/A
Study type: Interventional

Intracranial atherosclerotic disease (ICAD) is the most common cause of ischemical cerebrovascular events. The risk of stroke recurrence or death of ICAD patients remains very high. Even with aggressive medical management including dual antiplatelet therapy and strict management of risk factors, 12.2 percent of patients with 70-99 percent stenosis of intracranial artery had stroke or death during 1 year follow-up. In the real world, the 30-day risk of recurrent stroke of patients with aggressive medical management was as high as 20.2 percent. Balloon angioplasty and stent for intracranial artery have become important alternative treatments to prevent recurrent stroke for patients with severe intracranial atherosclerotic stenosis. Nevertheless, the SAMMPRIS trial has suggested intracranial stenting has higher stroke and death rate than aggressive medication with high peri-procedure complication rate. Previous nonrandomized studies have showed that stroke and death rate of angioplasty for ICAD patients with severe stenosis of intracranial artery is lower than that of aggressive medication. The primary purpose of this trial is to compare intracranial angioplasty plus aggressive medical management with aggressive medical management alone for the treatment of patients with 70-99 percent intracranial artery stenosis because of ICAD and to clarify the efficacy and safety of intracranial angioplasty through a multicenter, prospective, randomized, open-label, blinded end-point trial.
