BioTime’s Subsidiary OncoCyte Corporation And The Wistar Institute To Collaboratively Develop Cancer Diagnostics

BioTime, Inc. (NYSE MKT: BTX), and its subsidiary OncoCyte Corporation today announced that OncoCyte has entered into a Sponsored Research Agreement and a Material Transfer Agreement with The Wistar Institute to collaboratively develop lung cancer diagnostic products. As part of the collaboration, Wistar investigators are conducting a multi-center patient study in which they are assessing gene expression patterns in blood cells of patients with malignant versus non-malignant lung disease. OncoCyte scientists will analyze blood samples obtained from patients in the study to determine levels of tumor-associated proteins using its proprietary PanC-Dx diagnostic tests. PanC-Dx™ is a class of non-invasive cancer diagnostics based on a proprietary set of cancer markers characterized, in part, by broad gene expression patterns in numerous cancer types.

The inclusion of the PanC-Dx TM markers in Wistar's ongoing multi-center study may allow OncoCyte to more rapidly develop a diagnostic test for lung cancer to be marketed in the U.S. and other countries. The performance of markers tested in the study in determining the presence or the progression of disease in various categories of patients may determine the specific nature of the lung cancer test to be developed and the regulatory approval pathway that OncoCyte will pursue. OncoCyte will have an option to exclusively license any inventions, discoveries or technology developed by Wistar, or by OncoCyte using Wistar technology, in the course of the collaborative research.

Wistar investigators, led by Louise Showe, Ph.D., have previously demonstrated the feasibility of detecting early stage lung cancer by taking a snapshot of gene activity in circulating blood cells. Lung cancer remains a primary cause of cancer-related death, in part because there is no effective diagnostic test to screen patients for lung cancer at an early stage. The current study is being conducted on patients recruited through grant partners at multiple clinical sites. Thus far over 400 patient samples out of a planned total of 600 have been obtained. Completion of the study, which began mid-2012, is expected in mid-2014.
