CoAxia(TM), Inc. of Maple Grove, MN, have announced that
investigation of its NeuroFlo(TM) perfusion augmentation technology has
been extended to patients who do not respond to thrombolysis with the
drug tissue plasminogen activator (tPA), the only stroke therapy
currently approved by the US FDA. Already being evaluated as a stand
alone treatment for patients that are outside the three hour tPA
treatment window, NeuroFlo cerebral perfusion augmentation was
successfully performed for the first time on a patient who had
previously received tPA by the stroke team at University of Alberta
Hospital in Edmonton, Canada.
The procedure was performed by Dr. Rob Ashforth on a 35 year old
stroke victim whose symptoms and cerebral imaging showed no improvement
following administration of tPA. Following NeuroFlo treatment, the
patient had a significant improvement in blood flow to the brain and in
motor and speech function, with no adverse events. Co-principal
investigators, Drs. Ken Butcher, Derek Emery and Ashfaq Shuaib are
leading this 20 patient feasibility study to investigate the safety of
using cerebral perfusion augmentation in patients who receive tPA but do
not respond clinically. While thrombolysis is the only stroke treatment
proven safe and effective in a randomized trial, only a minority of
patients benefit from a near complete recovery. There remains
significant need for adjunctive treatments in this important patient
group.
Dr. Ashfaq Shuaib, Director of Stroke Services at the University of
Alberta said, "CoAxia is already conducting studies to demonstrate
that NeuroFlo treatment may be effective as a stand alone treatment, and
we are excited to extend this work to patients who do not respond to
pharmaceutical interventions. This feasibility study is an important
step to show that NeuroFlo treatment is a good adjunct to tPA
therapy."
Lori Austin, vice president Clinical Affairs commented, "The
NeuroFlo technology may be an ideal adjunct to tPA therapy by providing
global perfusion augmentation before, during, or after thrombolytics.
With the help of the team in Edmonton, we have taken our first step in
the clinical evaluation for this large group of patients".
The NeuroFlo treatment is intended to deliver increased blood flow
to the affected, but still salvageable, area of the brain in stroke
patients by increasing flow via collateral pathways "around" a
blocked artery. The therapy is accomplished with a unique, dual-balloon
catheter that creates a partial occlusion of the descending aorta and
redirects blood flow to the brain.
In addition to this feasibility study, CoAxia has two additional
stroke studies underway -- the SENTIS randomized pivotal trial of
patients up to 10 hours after stroke onset, and the Flo24 safety and
feasibility study of patients as late as 24 hours after stroke.
CoAxia, Inc. is a venture-backed, privately held, development-stage
company focused on providing perfusion augmentation therapies that
improve outcomes for patients with cerebral ischemia resulting from
stroke, vasospasm and other conditions.
