Safety and Efficacy of NeuroFlo in 8-24 Hour Stroke Patients (Flo 24)

This study has been completed.

CoAxia Identifier:
First received: February 16, 2007
Last updated: February 3, 2009
Last verified: February 2009
The purpose of this study is to assess the safety and feasibility of the NeuroFlo™ catheter in treating patients with ischemic stroke whose last time symptom-free was between 8-24 hours prior to treatment. The NeuroFlo device is intended to increase blood flow to the brain and potentially reduce the damage caused by stroke.

Condition Intervention Phase
Cerebrovascular Accident Device: NeuroFlo™ Catheter Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment

Primary Purpose: Treatment
Official Title: Safety and Efficacy of NeuroFlo in 8-24 Hour Stroke Patients

Further study details as provided by CoAxia:

Primary Outcome Measures:
  • Assessment of all adverse events from baseline to 30 days post-treatment. [ Time Frame: 30 Days ]

Secondary Outcome Measures:
  • Potential benefit will be assessed through collection of neurological indices at baseline, post-procedure, 24 hours, day 4 (or discharge), 30 and 90 days. [ Time Frame: 90 Days ]
  • Cerebral perfusion changes associated with device therapy will be assessed using MRI perfusion studies acquired at baseline and ≤ 4 hours post-procedure. [ Time Frame: ≤ 4 hours ]

Enrollment: 26
Study Start Date: February 2007
Study Completion Date: January 2009
Primary Completion Date: January 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Device: NeuroFlo™ Catheter
45 minute Treatment

Detailed Description:

The study is a prospective, single arm treatment feasibility trial to determine the baseline safety and feasibility of the NeuroFlo device in acute ischemic stroke patients whose last known time symptom-free is between 8-24 hours.

A maximum of 25 patients at 5 US sites and 25 patients at 10 Canadian & European sites may be enrolled in this initial study phase. An independent data safety and monitoring board will assess the safety of the treatment on a routine basis.
