Alzheimer’s Drug Discovery Foundation Funds Abiant, Inc. to Develop a
Positron Emission Tomography (PET) Imaging Diagnostic for Alzheimer's Disease

NEW YORK, NEW YORK (SEPTEMBER 9, 2009) – The Alzheimer’s Drug Discovery Foundation (ADDF)
announced today that it is providing a grant of $200,000 to Abiant, Inc. (Deerfield, IL), for the
development of a highly accurate imaging diagnostic for Alzheimer’s Disease.  Abiant, a privately held
company, is dedicated to the application of neuroimaging to improve the diagnosis and treatment of
neurologic and neuropsychiatric disorders.

Abiant’s diagnostic approach combines key advances in the analysis of Positron Emission
Tomography (PET) images of the brain.  The first of these was developed by Lisa Mosconi, PhD, Henry
Rusinek, PhD, and Wai Tsui, MS at the NYU School of Medicine's Center for Brain Health, directed by
Mony de Leon, EdD.  This advance allows the precise, automated measurement of glucose
metabolism in the hippocampus, a brain structure that is critical to new memory formation and which
is affected very early in Alzheimer’s disease.  Abiant is combining this with other key advances in
statistical analysis tools that consolidate information from many regions in the brain into measurable
patterns of disease progression.  In studies using patients from academic centers worldwide, these
approaches have been able to predict future decline, and to distinguish between types of dementia
with very high accuracy.

“Abiant’s diagnostic approach provides a potential path to clinician adoption and use of a powerful aid
in early, accurate diagnosis that has not yet been achieved,” says Howard Fillit, MD, ADDF’s Executive
Director. “The grant will enable Abiant to further validate and translate its approaches toward a
beneficial tool for the Alzheimer’s disease community.”

“We are very pleased that ADDF is helping to fund our development efforts,” comments Dawn
Matthews, Chief Executive Officer of Abiant.  “Not only will this help to accelerate our progress, but the
ADDF will be a valuable partner in the guidance of our work toward broad clinical use.”

Mony de Leon adds “PET imaging measurement of activity in the brain, and in particular the
hippocampus, can provide a powerful biomarker for the early and accurate detection of Alzheimer’s
disease.  We are very pleased to see this step toward the translation of our research advances to
clinical use.”

ADDF is awarding the grant through its affiliate The Institute for the Study of Aging, Inc.

About the Alzheimer’s Drug Discovery Foundation.
ADDF (www.alzdiscovery.org) is the only public charity whose sole mission is to accelerate the
discovery and development of drugs to prevent, treat and cure Alzheimer’s disease, related dementias
and cognitive aging. We award grants to leading scientists conducting breakthrough drug discovery
research.  ADDF uses a venture philanthropy model to bridge the worldwide funding gap between
basic research and later-stage development, using any return on investment to support new research.
Since 1998, we have received over 1,600 requests to fund new ideas for Alzheimer’s drugs. For all, we
provided expert reviews and recommendations to advance their programs. We granted more than
$35M to fund over 240 Alzheimer’s drug discovery programs in academic centers and biotechnology
companies in 12 countries.  The ADDF website carries the latest, vetted news on Alzheimer’s disease,
updated weekly.

About Abiant, Inc.
Abiant, Inc. uses proprietary image analysis methods and software to provide sensitive biomarkers of
drug effects and disease progression.  This imaging information is intended to accelerate and
improve accuracy of decision making in both disease diagnosis and drug development.  Abiant has
exclusively licensed technologies for accurate, automated measurement of information in PET images
from NYU Langone Medical Center.  The Company conducts imaging studies on novel pharmaceutical
compounds for drug development companies.  Abiant recently presented results of its analyses of
Alzheimer’s disease data at the International Conference on Alzheimer’s Disease (ICAD) and the
Human Amyloid Imaging (HAI) Conference.
