Acorda Therapeutics Presents GGF2 Preclinical Stroke Data at International Stroke Conference
Acorda Therapeutics, Inc. (Nasdaq: ACOR) announced data from studies
showing that Glial Growth Factor 2 (GGF2) can enhance recovery of
sensorimotor function in a preclinical model of stroke. The studies
expand on an existing body of preclinical work examining GGF2 in stroke,
and specifically explored various doses and frequency of administration
to assess optimal treatment regimens. The data were featured as a
late-breaking poster presentation at the American Heart
Association/American Stroke Association International Stroke Conference
in Honolulu, HI.
“These data confirm earlier preclinical study results showing that GGF2
can improve recovery of function following stroke. They also provide
valuable information about varying dosing regimens that will contribute
to the further development of GGF2,” said Anthony Caggiano, M.D., Ph.D.,
Acorda’s Vice President of Research and Development. “Previous studies
have shown that GGF2 can be effective in restoring function when
initiating therapy as long as seven days following a stroke. Currently
approved stroke interventions need to be administered within a few hours
of an event, which limits therapy to a small minority of people who
experience a stroke. Early data on GGF2 suggest a longer time window to
administer treatment, which represents a potentially critical advance.”
The poster, entitled “Optimized Dosing of Glial Growth Factor 2 in a
Middle Cerebral Artery Occlusion Model Increases GAP43 Expression,”
reviewed data from study groups receiving differing doses of GGF2 to
determine which dose was most effective in enhancing recovery of
sensorimotor function after stroke. This was measured by several
sensorimotor function tests, including limb placement. Treatment was
initiated 24 hours after the stroke. The study showed significant
improvements in sensorimotor recovery with GGF2 that were related to
dose and frequency of treatment. As was seen in previous studies,
improvements were not associated with reduced lesion volume, but in this
study were shown to be associated with increased expression of the
growth associated protein, GAP43, within the brain, both close to and
distant from the area of injury.
GGF2 is the leading development candidate from the Company’s neuregulin
program. Neuregulins are a class of naturally occurring protein growth
factors that have multiple effects on the nervous and cardiovascular
systems. Acorda is conducting a clinical program for GGF2 in heart
failure and preclinical development in a number of neurological
indications, including peripheral nerve injury and stroke. The first
clinical trial of GGF2, a Phase 1 study of GGF2 in patients with heart
failure, was completed in late 2012.
About Acorda
Therapeutics
Acorda Therapeutics is a biotechnology company focused on developing
therapies that restore function and improve the lives of people with MS,
spinal cord injury and other neurological conditions.
Acorda markets AMPYRA®
(dalfampridine) Extended Release Tablets, 10 mg, in the United
States as a treatment to improve walking in patients with multiple
sclerosis (MS). This was demonstrated by an improvement in walking
speed. AMPYRA is marketed outside the United States as FAMPYRA®
(prolonged-release fampridine tablets) by Biogen Idec under a licensing
agreement from Acorda. AMPYRA and FAMPYRA are manufactured under license
from Alkermes Pharma Ireland Limited.
The Company also markets ZANAFLEX
CAPSULES® (tizanidine hydrochloride) and Zanaflex
tablets, a short-acting drug for the management of spasticity. Acorda
also receives sales royalties on tizanidine hydrochloride capsules, an
authorized generic version of ZANAFLEX CAPSULES distributed by Watson
Pharmaceutics, Inc. under its agreement with Acorda.
Acorda has an industry-leading pipeline of novel neurological therapies.
The Company is developing Diazepam Nasal Spray for treatment of certain
epileptic seizures. It is also studying AMPYRA to improve a range of
functional impairments caused by MS, as well as its potential for use in
other neurological conditions, including cerebral palsy and post-stroke
deficits. In addition, Acorda is developing clinical stage compounds
AC105 for acute treatment of spinal cord injury, GGF2 for treatment of
heart failure and rHIgM22, a remyelinating monoclonal antibody, for the
treatment of MS. GGF2 is also being investigated in preclinical studies
as a treatment for neurological conditions such as stroke and spinal
cord injury. Chondroitinase, an enzyme that encourages nerve plasticity
in spinal cord injury, is in preclinical development.
