SACRAMENTO, California (July 18, 2018) – Roy Ervin Twyman, MD, PhD, an academic neurologist with nearly 20 years' experience in neuroscience pharmaceutical drug development, will join the NeuroVision Imaging Inc. Board of Directors on July 20.

NeuroVision is developing and studying an experimental, breakthrough, low-cost, noninvasive, eye-imaging system for measuring autofluorescence, which can detect amyloid beta (Aβ) plaque in the eye. Aβ plaque deposits in the brain are a hallmark sign of Alzheimer's disease, and histological evidence shows that Aβ plaque also accumulates in the retina, the photoreceptor and nerve complex at the rear of the eye.

Twyman recently retired as senior vice president at Janssen Pharmaceutical Research & Development LLC, where he was the Alzheimer's disease area leader in the Neuroscience Therapeutic Area. He joined the company, previously known as the RW Johnson Pharmaceutical Research Institute, in 1998 after nine years in academia, most recently as an associate professor in the University of Utah's department of neurology and department of pharmacology and toxicology.
At Janssen, Twyman had end-to-end oversight responsibilities for the company's Alzheimer's disease area – including discovery, chemistry, biomarkers, translational medicine, early and late clinical development, diagnostics, and solutions involving patient care. He also has extensive experience in developing therapeutics for epilepsy, migraine, multiple sclerosis, depression and schizophrenia.

"With Dr. Twyman's extensive experience in Alzheimer's drug development and his training in medicine and the neurosciences, he will bring a unique and invaluable perspective to our board," said Steven Verdooner, NeuroVision CEO. "As drugs move toward eventual approval, the need for early, noninvasive identification of people at risk for Alzheimer's disease is of high importance to pharmaceutical companies, and especially to patients who will potentially benefit from these new treatments. Dr. Twyman brings a unique and profound perspective of the science behind Alzheimer's, clinical trials and commercial considerations."

Twyman has served on advisory committees and panels of the U.S. Food and Drug Administration and the Institute of Medicine. He recently participated in a special committee on epilepsy of the National Institute of Neurological Disorders and Stroke, and he now co-chairs a NINDS workshop on antiepileptogenesis and epilepsy disease modification.
