Pain Therapeutics Announces Initiation of a Phase II Study in Alzheimer’s Disease

AUSTIN, TX, USA I December 06, 2018 I Pain Therapeutics, Inc. (Nasdaq: PTIE), a biopharmaceutical company, announced today the initiation of a Phase II study to evaluate PTI-125 as a potential first line treatment in patients with Alzheimer’s disease. This clinical study is supported by a research grant award from the National Institute on Aging (NIA), the primary Federal agency supporting new research in Alzheimer’s disease.

“There is a profound and timely need to develop new drugs for Alzheimer’s,” said Remi Barbier, President & CEO. “We are excited about the clinical potential of PTI-125, as this drug candidate represents a promising new approach for the treatment and prevention of Alzheimer’s.”

This Phase IIa study is designed to evaluate safety, tolerability, pharmacokinetics and biomarkers in 12 patients with mild-to-moderate Alzheimer’s treated with PTI-125 twice-daily for 1 month. In mid-2019, the Company expects to conduct a Phase IIb study in 36 patients with Alzheimer’s treated with PTI-125 for 3 months. Collectively, the Phase IIa and Phase IIb studies are intended to demonstrate target engagement, and possibly prepare PTI-125 for a pivotal efficacy program.

About PTI-125
PTI-125 is the Company’s proprietary drug candidate that targets an altered form of Filamin A. Publications show that altered Filamin A is responsible for multiple pathologies observed in the Alzheimer’s brain. PTI-125 restores altered Filamin A back to its proper conformation. This results in dramatically improved brain health in animal models, including reduced amyloid deposits, reduced neuroinflammation, improved insulin resistance in the brain and improved learning and memory. Importantly, PTI-125 is not dependent on clearing amyloid from the brain.

The science and technology for PTI-125 is published in prestigious peer-reviewed journals, including Journal of Neuroscience, Neurobiology of Aging, and Neuroimmunology and Neuroinflammation, and has been awarded multiple competitive research grants from the NIA.

The underlying science for PTI-125 also supports the development of a biomarker/diagnostic to detect Alzheimer’s disease with a simple blood test, possibly years before any symptoms appear. 

About Alzheimer's Disease
Alzheimer’s Disease (AD) is a progressive brain disorder that destroys memory and thinking skills. Eventually, a person with AD may be unable to carry out even simple tasks. Currently, there are no drug therapies to halt AD or slow its progression. As baby boomers age, the number of people with AD is expected to soar in the coming years, both in the U.S. and abroad.
