DAEJEON, South Korea, and OSONG, South Korea, July 16, 2018 /PRNewswire/ -- Peptron Inc. (087010:KS), a Korean-basedpublic pharmaceutical company that focuses on peptide engineering and developing sustained-release medicine technology, announced today publication of preclinical data from a team of international scientists showing a new sustained-release (SR) exendin-4
Parkinson's disease, a chronic and progressive movement disorder, is caused by the predominate loss of dopamine-producing ("dopaminergic") neurons in an area of the brain called substantia nigra. It is the second most common neurodegenerative disease, afflicting nearly one million people in the United States. This research builds on a number of other studies that have proposed GLP-1 receptor agonists as a new treatment for neurodegenerative diseases including Parkinson's disease, Alzheimer's disease, Huntington's disease, traumatic brain injury, stroke, and peripheral neuropathy. Peptron recently expanded an exclusive license of intellectual property from the U.S. National Institutes of Health that covers the delivery and use of SR-exenatide for the treatment of neurodegenerative disorders. In addition, the company has begun operations of a GMP manufacturing facility to produce SR-exenatide for a Phase 2 clinical trial in Parkinson's disease and for further evaluation of SR-exenatide for the treatment of Alzheimer's disease and related disorders.
"We are proud to apply our decades of experience in developing sustained-release therapeutics to the great unmet medical need of millions of people around the world who suffer from Parkinson's disease," said Ho-Il Choi, PhD, Chief Executive Officer and Director of Peptron. "The peer-review and publication of this data is an important step in confirming the ability of our novel SR-exenatide drug to cross the blood-brain barrier and deliver long-acting therapeutic effects of the neuroprotective peptide. We are looking forward to beginning our Phase 2 clinical trial in Parkinson's disease and advancing a novel therapeutic that could fight neurodegeneration."
The study first determined a clinically relevant efficacious dose of Peptron's SR-exenatide (PT302). A single subcutaneous administration of PT-302 resulted in sustained elevations of exendin-4 in plasma for more than 20 days in adult rats. Post-lesioning treatment of PT302 significantly increased brain tyrosine hydroxylase immunoreactivity (TH-IR), a measure of dopaminergic neurons, in the lesioned substantia nigra and striatum. There was a significant correlation between plasma exendin-4 levels and TH-IR in the substantia nigra and striatum on the lesioned side. The data suggests that post-treatment with PT302 at a clinically relevant dose provides long-lasting exendin-4 release and reduces neurodegeneration of nigrostriatal dopaminergic neurons in a 6-hydroxydopamine rat model of Parkinson's disease.
