- PTI-125, an Experimental Drug, Restored Receptor Function and Significantly Improved Working Memory and Spatial Ability in a Transgenic Mouse Model of Alzheimer’s Disease
AUSTIN, Texas, June 01, 2017 (GLOBE NEWSWIRE) -- Pain Therapeutics, Inc. (Nasdaq:PTIE), a biopharmaceutical company, today announced a technical publication authored by its scientists and academic collaborators that further demonstrates a potentially promising new therapeutic approach to treat Alzheimer’s Disease with PTI-125, a new drug candidate with a novel mechanism of action.
Transgenic mice with genetic mutations for Alzheimer’s disease were treated with PTI-125. After two months of treatment, the mice showed significant improvements in working memory, spatial ability and social behavior. Importantly, their brains also showed significant improvements in multiple Alzheimer’s neuropathologies, such as improved function of receptors key to cognition; improved synaptic function; decreased neuroinflammation; decreased insulin resistance; reduced amyloid plaques; and reduced tau hyperphosphorylation. This study is published in the current issue of Neurobiology of Aging, one of the highest-ranking journals in its field, and was funded in part by a research grant from the National Institutes of Health (NIH).
“These data suggest PTI-125 improves cognition and slows the course of Alzheimer’s Disease,” said Remi Barbier, President & CEO. “These are exciting potential health benefits. Through innovative science and our desire to work collaboratively, our vision for PTI-125 is to advance the treatment of Alzheimer’s Disease.”
An Investigational New Drug (IND) application to test PTI-125 in humans is on-track for submission to the U.S. Food and Drug Administration (FDA) in the third quarter of 2017.
The Neurobiology of Aging (Vol 55, July 2017, Pages 99–114) publication is titled “PTI-125 binds and reverses an altered conformation of filamin A to reduce Alzheimer’s disease pathogenesis”.

About Alzheimer’s Disease and PTI-125
Alzheimer’s Disease (AD) is a progressive brain disorder that slowly destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks. There is no approved drug therapy to reverse, or even halt, the course of AD. PTI-125 is an oral, small molecule drug candidate that was designed in-house and characterized by outside collaborators. PTI-125 has been shown to significantly improve AD neuropathologies in mouse models of the disease and in post-mortem brain tissue from AD patients, including receptor dysfunctions, neuroinflammation, tau hyperphosphorylation, insulin resistance and plaques and tangles that are hallmarks of AD.
To date, the underlying science for PTI-125 has been published in Journal of Neuroscience, Neurobiology of Aging, Journal of Biological Chemistry, PLOS-One and other peer-reviewed scientific journals.
Pain Therapeutics owns worldwide commercial rights to PTI-125 and related technology.
