Basilar Artery Embolism 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.

Basilar Artery International Cooperation Study

BASICS

Start date: October 2011
Phase: N/A
Study type: Interventional

Rationale: Recently our study group reported the results of the Basilar Artery International Cooperation Study (BASICS), a prospective registry of patients with an acute symptomatic basilar artery occlusion (BAO). Our observations in the BASICS registry underscore that we continue to lack a proven treatment modality for patients with an acute BAO and that current clinical practice varies widely. Furthermore, the often-held assumption that intra-arterial thrombolysis (IAT) is superior to intravenous thrombolysis (IVT) in patients with an acute symptomatic BAO is challenged by our data. The BASICS registry was observational and has all the limitations of a non-randomised study. Interpretation of results is hampered by the lack of a standard treatment protocol for all patients who entered the study. Objective: Evaluate the efficacy and safety of IAT in addition to best medical management (BMM) in patients with basilar artery occlusion. Study design: Randomised, multi-centre, open label, controlled phase III, treatment trial. Study population: Patients, aged 18 years and older, with CTA or MRA confirmed basilar occlusion. Intervention: Patients will be randomised between BMM with additional IAT versus BMM alone. IAT has to be initiated within 6 hours from estimated time of BAO. If treated with as part of BMM, IVT should be started within 4.5 hours of estimated time of BAO. Main study parameters/endpoints: Favorable outcome at day 90 defined as a modified Rankin Score (mRS - functional scale) of 0-3.
