Abiant, Inc. Presents at Conference on Clinical Trials in Alzheimer's Disease
Deerfield, ILLINOIS - - October 30, 2009 - - Abiant, Inc. presented results of recent analysis work at the 2nd Conference on Clinical Trials in Alzheimer's Disease (CTAD 2009) in Las Vegas, Nevada. Abiant's presentation, titled "Regional Cerebral Glucose Metabolism Predicts Decline in MCI Subjects and Provides a Sensitive Biomarker of Disease Progression", described the Company's advances in the measurement of glucose metabolism in patients who exhibit "prodromal", or pre-Alzheimer's diagnosis, symptoms of cognitive impairment. The work was co-authored with researchers from the New York University School of Medicine Center for Brain Health, led by Dr. Mony de Leon, and was presented by Dawn Matthews, CEO of Abiant.
In the work presented, Abiant used proprietary analysis tools, to discriminate between Mild Cognitive Impairment patients who would decline in cognitive and clinical measures over the subsequent 18 months versus those who would not. Abiant also demonstrated the ability to measure progressive decline in cerebral glucose metabolism during the 18 months, and an important correlation between the brain regions that declined, measured at baseline with the amount of clinical decline (changes in cognitive scores) during the 18 months.
To accomplish this, Abiant used novel methods developed by Lisa Mosconi, PhD and colleagues at New York University (Mosconi et al, 2005; Yi et al, 2008) , and additional pattern identification software developed under the direction of Stephen Strother, PhD (Strother et al, 2002). The methods developed by Mosconi et al are key to measuring changes in the hippocampus, a key region of decline in Alzheimer's Disease. The pattern identification technology uses multivariate analysis and other techniques to determine brain networks, or related regions, of disease or drug effect. By measuring relationships between the regions of the brain that are affected, this approach increases the interpretability and power of image analysis. The data for Abiant's analysis consisted of the Positron Emission Tomography (PET) imaging scans of 71 subjects from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database.
The capabilities demonstrated by Abiant are important to both drug development trials and disease detection. In drug trials, inclusion of subjects who would not actually decline clinically, even without drug, makes it difficult to establish therapeutic effect. The ability to better characterize a clinical trial population can help to confirm that inclusion criteria are met, or to better interpret results. Also in drug trials, an objective biomarker that correlates to clinical progression can provide increased power over cognitive tests or clinical measures that have historically been subject to high variability. in disease detection, the ability to assess prognosis of decline rather than simply diseased or not can also be helpful in patient management.

Abiant designs and conducts imaging studies and performs image analysis for pharmaceutical companies to evaluate the effects of pipeline or marketed compounds upon the central nervous system. With funding recently received from the Alzheimer's Drug Discovery Foundation (ADDF), Abiant is also developing an image analysis diagnostic for Alzheimer's Disease and other dementias.
ADNI is a $60 million, 5-year public-private partnership to test whether serial magnetic resonance imaging (MRI), positron emission tomography (PET), other biological markers, and clinical and neuropsychological assessment can be combined to measure the progression of mild cognitive impairment (MCI) and early Alzheimer’s disease (AD).
