| Data from First Clinical Trial of GGF2 in Heart Failure Presented at the American College of Cardiology 62nd Annual Scientific Session |
“We have completed the first in human trial with GGF2 in patients with
heart failure, and especially want to thank our patients who volunteered
for this important study. We are very encouraged by the results,” said
“Preclinical studies have suggested that GGF2 may improve heart function
through direct repair of cardiac muscle, a novel mechanism of action.
This first clinical trial in patients with heart failure identified a
maximally tolerated GGF2 dose and key safety parameters to be monitored
in future studies. This information supports continued development of
the compound as a potential treatment for heart failure,” said This was a double-blind, placebo controlled, escalating single dose clinical trial that included 40 patients with advanced heart failure. Safety and exploratory efficacy were monitored for 90 days in patients randomized to receive various doses of GGF2 or placebo. Safety Findings In this study, a single dose of GGF2 in patients with heart failure was generally well tolerated up to 0.75 mg/kg. Among participants receiving GGF2, the most commonly observed adverse events were headache, site injection reaction and gastrointestinal symptoms. There were no notable effects of treatment on hematology or electrocardiogram, and no adverse events led to withdrawal from the study. A dose-limiting adverse event of hepatotoxicity (liver injury) meeting Hy’s Law criteria (elevated ALT, AST and bilirubin) occurred in the highest-dose cohort. The patient’s liver function tests and bilirubin had returned to normal by two weeks after dosing. There was also one reported case of uroepithelial carcinoma, a form of cancer in the cells that line the bladder, which was diagnosed three months after dosing in the highest-dose cohort. The patient’s baseline urinalysis showed the presence of red blood cells, indicating that the tumor was likely present prior to dosing. Ejection Fraction Findings A left ventricle ejection fraction of 55% or higher is considered normal; all participants in the Phase 1 GGF2 trial had left ventricle ejection fraction of less than 40%. Trial participants receiving GGF2 showed a consistent and dose-responsive trend towards improving left ventricular ejection fraction over 28 and 90 days compared to placebo. Mean ejection fractions at screening in the treatment and placebo groups were 27% and 29%, respectively. For the cohort receiving the maximally tolerated dose (0.75 mg/kg) of GGF2, the mean ejection fraction at screening was 28% and the absolute mean changes in ejection fraction at day 8, day 14, day 28, and day 90 were 5%, 12%, 12.0% and 9.0%, compared to absolute mean changes of -1%, -1%, 0% and 2% for the placebo group; thus, the mean ejection fraction for this GGF2 group at day 28 was 40%, versus 29% for placebo.

The About GGF2 GGF2 is the leading development candidate from Acorda’s neuregulin program. Neuregulins are a class of naturally occurring protein growth factors that have multiple effects on the nervous and cardiovascular systems. Preclinical studies demonstrate that GGF2 acts directly to repair cardiac muscle and improve its contractile function. No currently available therapies do this, and GGF2 may therefore offer an important new treatment option for people with heart failure. In addition to its clinical program in heart failure, the Company also has preclinical development programs for GGF2 in a number of neurological indications, including peripheral nerve injury and stroke.
About
Acorda markets AMPYRA®
(dalfampridine) Extended Release Tablets, 10 mg, in
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 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. Acorda Forward-Looking Statements
