OncoCyte to Present Cancer Diagnostic Clinical Study Data at AACR Annual Meeting

- BioTime subsidiary’s data collected from prospective clinical studies in bladder and breast cancer -

ALAMEDA, Calif.--(BUSINESS WIRE)--February 6, 2015--BioTime, Inc. (NYSE MKT:BTX) and its subsidiary OncoCyte Corporation today announced that two abstracts, summarizing clinical studies of OncoCyte’s PanC-Dx™ diagnostic products for bladder and breast cancer, have been accepted for poster presentation at the American Association for Cancer Research (AACR) Annual Meeting being held April 18-22, 2015 in Philadelphia. PanC-Dx™ is a class of non-invasive cancer diagnostics based on OncoCyte’s proprietary set of cancer markers, which were discovered by company scientists through an analysis of broad gene expression patterns in numerous cancer types. These markers are the subject of multiple pending patent claims filed in numerous countries worldwide and are owned by OncoCyte.

“Solid diagnostic test performance data derived from large prospective clinical studies is crucial for adoption of novel diagnostic tests by clinicians and payers,” said Joseph Wagner, PhD, OncoCyte’s Chief Executive Officer. “We are excited by the opportunity to present data from clinical trials of the bladder and breast cancer diagnostics that we are developing. These tests are designed to be accurate and less invasive methods to detect and monitor the presence of cancer as compared to current cancer diagnostic procedures.”

“The PanC-Dx™ clinical data presentations at the upcoming AACR Annual Meeting are the first of multiple, significant milestones that BioTime and its subsidiaries expect to achieve in 2015. These presentations of clinical data reflect our steady progress toward commercializing cancer diagnostic products aimed at addressing large and growing markets,” said Dr. Michael D. West, Ph.D., BioTime’s Chief Executive Officer.

The first presentation will provide a summary of the clinical data and assay development progress of OncoCyte’s bladder cancer diagnostic test. Data obtained from two prospective clinical studies will be presented. The goal of the first study, recently completed at a leading medical institution with an international reputation for excellence and discovery, was to assess the performance of OncoCyte’s proprietary diagnostic technology in detecting the most common type of bladder cancer, urothelial carcinoma (UC) (previously designated transitional cell carcinoma). Study investigators collected approximately 100 urine samples from patients undergoing urine cytology for the diagnosis of either primary or recurrent bladder cancer. Patient urine samples were assessed microscopically for the presence of cancer cells using the current standard-of-care method of cytopathology; in parallel, OncoCyte scientists analyzed the remaining portion of the urine samples for gene expression, including expression of OncoCyte’s proprietary PanC-Dx™ markers. A statistical analysis was performed and a panel of markers that discriminates UC from non-cancerous conditions was identified.

The goal of the second bladder cancer clinical trial, which will involve up to 1,400 patient samples obtained from at least four and as many as nine large urology clinics located throughout the United States, is to compare the performance the marker panel derived from the first clinical study to the performance of cystoscopy. Investigators in the trial are collecting urine samples from patients undergoing cystoscopy for the diagnosis of either primary or recurrent bladder cancer. Cystoscopy and biopsy results will be compared to the performance of OncoCyte’s proprietary diagnostic test panel. Thus far over 450 patients have been enrolled in this study; enrollment should be completed in 2015.

Overall markets for bladder cancer diagnostics are large and growing. Based on National Cancer Institute statistics released in 2012, it was estimated that in 2013 over 72,000 new cases of bladder cancer would occur in the United States and a total of over 550,000 men and women alive would have a history of bladder cancer and be subject to recurrence surveillance testing using cystoscopy or urine cytology.

The second presentation will provide a summary of the clinical data and assay development progress of OncoCyte’s breast cancer diagnostic test. Data obtained from a large, prospective clinical study involving 600 patients being conducted at Scottsdale Medical Imaging Laboratories will be presented. The goal of this study which has nearly completed enrollment, is to assess the performance of OncoCyte’s proprietary diagnostic technology in discriminating patients with malignant breast lesions from those with negative or benign findings. Study investigators are collecting blood samples from patients undergoing screening or diagnostic mammography. Patient blood samples are being assessed for expression of OncoCyte’s PanC-Dx™ markers using proprietary assays and the results compared to radiological and pathology findings.

Mammography has been widely used since the 1970s for breast cancer screening in asymptomatic women; in 2010 over 30 million screening mammograms were performed in the US alone. The American Cancer Society and the National Comprehensive Cancer Network both recommend screening mammography every year starting at age 40, which has been associated with relative reduction in breast cancer mortality of 15% to 20%. However, the NCI estimates that approximately 20% of all breast cancers are not detected by mammography during annual screening which indicates there is an unmet need for a breast-cancer screening test with superior specificity and sensitivity when compared to standard screening mammography.

About OncoCyte Corporation

OncoCyte, a majority-owned subsidiary of BioTime, Inc., is developing novel products for the diagnosis and treatment of cancer in order to improve the quality and length of life of cancer patients. Based on large unmet need, market size, and data generated thus far from patient sample screening, OncoCyte is initially focusing its efforts on developing PanC-Dx™ diagnostic products for use in detecting breast, bladder, and lung cancers. 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 PanC-Dx™ biomarkers were discovered as a result of ongoing research within OncoCyte and BioTime on the gene expression patterns associated with embryonic development. This research has demonstrated that many of the same genes associated with normal growth during embryonic development are abnormally reactivated by cancer cells. These genes regulate such diverse processes as cell proliferation, cell migration and blood vessel formation. Many of these genes have not been previously associated with cancer. Moreover, expression of a large subset of these genes is conserved across numerous cancer types (e.g. cancers of the breast, colon, ovaries, etc.), suggesting these genes may control fundamental processes during cancer growth and progression. In addition to their potential value in developing diagnostic biomarkers, an understanding of the pattern of expression of these genes may also enable the development of powerful new cancer therapeutics that target rapidly proliferating cancer cells.
