Basilar Artery Occlusion 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.

Endovascular Treatment for Acute Basilar Artery Occlusion

Start date: February 21, 2021
Phase: N/A
Study type: Interventional

Rationale: Recently, two prospective multicenter RCT reported a potential beneficial effect of endovascular thrombectomy (EVT) in patients with an acute symptomatic basilar artery occlusion (BAO). However, the high rate of crossover in BEST study and the long-term of recruitment in BASICS study influenced the validity of the results. Besides, a recently prospective clinical registry with large sample size (BASILAR) showed a significantly beneficial effect of EVT in BAO patients. Objective: To assess the effect of EVT in addition to best medical management (BMM) compared to BMM alone, in patients with BAO, caused by a CTA/MRA confirmed occlusion of the basilar artery on functional and safety outcome. Study design: This is a parallel group, randomized clinical trial of EVT with BMM versus BMM. The trial has observer blind assessment of the primary outcome and of neuro-imaging at baseline and follow up. Study population: Patients with acute ischemic stroke and a confirmed basilar artery occlusion by CTA/MRA. Main study parameters/outcomes: The primary effect parameter will be favourable outcome at day 90 defined as a modified Rankin Score (mRS) of 0-3. The estimate will be adjusted for the known prognostic variables age, pre-stroke mRS, time from onset to randomization, stroke severity (NIHSS) and collaterals and adjusted and unadjusted estimates with corresponding 95% confidence intervals will be reported.
