About this study

Official title: Prospective, Single-arm, Multi-center Study to Confirm the Safety and Performance of the ANA 5F Advanced Neurovascular Access®, in Combination With a Stent Retriever in Patients With Acute Ischemic Stroke (ANAIS)

Prospective, single-arm, multi-center study to assess the safety and performance of the ANA 5F Advanced Neurovascular Access®, in combination with a stent retriever in patients with acute ischemic stroke.

Read the detailed description

ANA 5F Advanced Neurovascular Access®: distal access catheter system designed to assist in neurovascular procedures by facilitating the insertion and guidance of other devices (i.e. retrieval devices and intravascular catheters) and temporarily restricting blood flow at the target position.

The objective of this study is to confirm the safety and performance of the ANA 5F device to be used as a tool to facilitate the Solitaire stent retriever placement and provide temporary restriction of blood flow in stroke patients undergoing neurothrombectomy for an acute large vessel occlusion (LVO) treated 24 hours from symptom onset (last time the subject was seen well).

Population: Up to 30 Participants with Acute Ischemic Stroke (AIS), indicated for treatment with ANA 5F device in combination with Solitaire stent retriever, whose stroke is attributable to an occlusion of a large artery in the neurovasculature.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NeurothrombectomyDevice

    Also called Mechanical thrombectomy (MT)

    The ANA 5F device is intended to be inserted, be navigated to the neurovascular anatomy inside an outer catheter and be used as a conduit for insertion and guidance of intravascular catheters and retrieval devices into a selected blood vessel. The funnel is deployed by retracting the conduit catheter and is intended, when deployed, to provide temporary vascular flow restriction.

    The device is indicated for the introduction of interventional devices into the neuro vasculature, during interventions for restoring blood flow in patients experiencing acute ischemic stroke due to large vessel occlusion.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Successful reperfusion, defined as rate of patients achieving mTICI ≥2b.

    Successful reperfusion, defined as rate of patients achieving mTICI ≥2b in the target vessel within three passes of the ANA 5F before the use of rescue therapy, assessed by the Core Lab.

    Measured: Day0. Intraoperative

  2. The composite of symptomatic Intracranial Hemorrhage (sICH) within 24 hours (-8 / +12 h) post-procedure, together with serious adverse device effects.

    The composite of symptomatic Intracranial Hemorrhage (sICH) within 24 hours (-8 / +12 h) post-procedure, together with serious adverse device effects (excluding those already counted in sICH) at Day 5 (± 12 h) or discharge (whatever comes first).

    Measured: 24 hours (-8 / +12 h) post-procedure

Secondary outcomes (1)
  1. Occurrence of Intracranial Hemorrhage (ICH); any symptomatic or asymptomatic ICH

    Measured: 90 days

Questions about this trial

What is this clinical trial studying?

A study testing Neurothrombectomy in people with Acute Ischemic Stroke, run by Anaconda Biomed S.L. at 3 sites in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 29 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Successful reperfusion, defined as rate of patients achieving mTICI ≥2b. (time frame: Day0. Intraoperative). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jul 2023.
