Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Study Groups

Best medical management.
Best medical management consists of the standard of care of patients with acute ischemic stroke according to existing local protocols and guidelines, and may include IV thrombolysis.
If treated with IVT as part of BMM, IVT should be started within 4.5 hours of estimated time of BAO.
No interventions assigned to this group
Additional intra-arterial treatment.
Best medical management followed by intra-arterial treatment and best medical management
Intra-arterial treatment
IA therapy has to be initiated within 6 hours of estimated time of basilar artery occlusion. If an appropriate thrombus or residual stenosis is identified, the choice of IA strategy wil be made by the treating neurointerventionalist. Choice of therapy depends on local approval and experience. If IA thrombolysis is the chosen strategy, a maximum of 22 mg of IA rt-PA or 1.500.000 Units of Urokinase may be given. Stenting is allowed in the presence of a high-grade vertebral artery stenosis or occlusion hampering adequate endovascular access to the basilar artery and in case of a residual high-grade basilar artery stenosis. The use of any other treatment strategy depends on local approval and experience, and is only allowed after prior approval of the steering committee.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Basilar artery occlusion (BAO) confirmed by CTA or MRA.
* Age 18 years or older (i.e., candidates must have had their 18th birthday).
* If IVT is considered as part of best medical management, IVT should be started within 4.5 hours of estimated time of BAO. (Estimated time of BAO is defined as time of onset of acute symptoms leading to clinical diagnosis of BAO or if not known last time patient was seen normal prior to onset of these symptoms).
* Initiation of IAT should be feasible within 6 hours of estimated time of BAO.
Exclusion Criteria
* Females of childbearing potential who are known to be pregnant and/or lactating or who have positive pregnancy tests on admission.
* Patients who require hemodialysis or peritoneal dialysis.
* Other serious, advanced, or terminal illness.
* Any other condition that the investigator feels would pose a significant hazard to the patient if thrombolytic therapy is initiated.
* Current participation in another research drug treatment protocol (patient cannot start another experimental agent until after 90 days).
* Informed consent is not or cannot be obtained.
* High-density lesion consistent with hemorrhage of any degree.
* Significant cerebellar mass effect or acute hydrocephalus.
* Bilateral extended brainstem ischemia.
