Enzo Biochem Announces New Molecular Platform and First Product for Early Focus on Cervical Cancer Progression

Novel Technology Allows for Multiplex Analysis of Cell Function and Identity in Single Assay
NEW YORK, NY, February 10, 2015- Enzo Biochem, Inc. (NYSE: ENZ) today announced the development of a new novel platform with consequential and broad application for detection of genotypic and phenotypic markers via flow cytometry, as well as the first product for its use addressing the cervical cancer testing market.
The platform, FlowScript™, allows for the multiplex analysis of cell function and identity in a single assay through the simultaneous examination of thousands of individual cells.
The Enzo HPV E6/E7 assay, the first product developed for use with the FlowScript technology platform, addresses the $1 billion cervical cancer testing market.  It enables the identification of certain upregulated oncogenes that can be indicative of cancer progression, allowing closer monitoring of patients exhibiting this condition. The new Enzo assay is designed to establish association between the expression of oncogenes and the progression of cervical cancer across a number of high risk HPV subtypes.
Enzo Clinical Laboratory has submitted an application to the New York State Department of Health in advance of offering services based on the FlowScript assay.  Upon receiving approval, Enzo will be the first clinical laboratory to provide this assay to physicians and other clinical labs, to which it will also make available key reagents for purchase.
The FlowScript platform is the result of an integrated effort across the entire Enzo spectrum, and was developed along with key opinion leaders from both the life sciences and clinical fields.  “FlowScript HPV E6/E7 represents another milestone, following the development of our AmpiProbe™ platform, in the execution of Enzo's strategic plan of developing, producing and providing clinically relevant products and services built upon Enzo's proprietary technology, underscored by numerous patents and patent applications,” said Elazar Rabbani, Ph.D., Chairman and CEO. 
"Both the platform and the first product were developed in under two years from the initial effort to clinical submission" added Kara Cannon, Global Head of Marketing and Sales for Enzo Life Sciences. "To have been able to execute research and development, process optimization, design manufacturing and quality assurance protocols, produce multiple test lots, validation and to coordinate key opinion leader input for this project in such a relatively short time period highlights Enzo's integrated capabilities in developing technology platforms and bringing commercially relevant products to market.  Enzo will utilize a bifurcated marketing approach offering both products and services based upon this key platform."
"Enzo's HPV E6/E7 assay is the result of an intense product development and validation effort by the Enzo Life Science and Clinical Lab team," said Dieter Schapfel, MD, Medical Director of Enzo Clinical Labs. "To provide a sense of the project, we analyzed more than two hundred different nucleic acid sequences to address a complex number of HPV targets detected in the assay interpretation. Optimization of reaction conditions and ancillary components has resulted in a product with high quality, well-designed controls resulting in fail-safe functionality. Evaluation of the assay and clinical validation performed for this project involved more than 1500 clinical samples and the combined efforts of both our technical groups, along with outside collaborators. The result is that we have taken an extremely complex analytical procedure and have distilled it down to a user-friendly, simple to­ implement protocol that fits the clinical laboratories' standard workflow. "
In effect, Enzo has positioned the new product as "a snapshot cell query" by allowing the analysis of  mRNA transcript expression in individual cells in a mixed cell population. By studying whether a gene or a set of genes is turned on or off, rather than whether they are present, it is possible to obtain clinically relevant information at the single cell level. Such analysis provides comparative, actionable data examining disease versus healthy state.  Currently Enzo has  FlowScript based products under development for the identification of specific biomarkers related to cancer as well as those related to autoimmune diseases.
FlowScript HPV E6/E7 contains controls for assuring operator consistency as well as a technical design to cover numerous aspects of the procedure, from the initial assay setup though the instrumentation settings and interpretation of the data. It improves efficiency by reducing the hands-on time required in other flow-based assays, in addition to being adaptable for use with virtually any flow cytometer on the market as well as any sample collection device.
The FlowScript platform is anticipated to be further utilized for applications related to women’s health, oropharyngeal and anal cancer, infectious disease, immune-mediated disorders including autoimmunity, metabolic disorders, drug responsiveness, patient monitoring and drug development.
