About the Company
Theranostics represents a new reality of molecular medicine whereby therapy is prescribed in a truly personalized and targeted manner: the merger of therapeutics and diagnostics.
Biomarkers that are both the therapeutic targets AND the diagnostic will drive this new paradigm. Since almost all therapeutic targets are PROTEINS, not genes, we believe that protein biomarkers represent the future of the theranostic arena.
The not so distant future of pharmaceutical development and clinical implementation will require patient stratification and the emergence of COMPANION DIAGNOSTICS (RX/DX): matching/requiring of diagnostic tests with many new compounds receiving regulatory approval. The Company's collaborations with leading pharmaceutical companies will provide innovation and leadership in this emerging new area.
For the pharmaceutical company, our assays are intended to provide critical information as to drug activity, selectivity and specificity. The Company’s proprietary technology and assays provide the pharmaceutical scientist, the clinical trial clinician, and the treating physician with the state of the drug target PATHWAYS for each patient from a tiny biopsy sample or cell lines in culture. The assays can provide the missing piece of information for personalized medicine, and can provide the pharmaceutical companies with the correct set of biomarkers that can be used to identify which patients most likely will respond to a specific drug, thus decreasing the time and cost of clinical trials. Unlike existing genomic diagnostic platforms, our assay using our proprietary diagnostic tools, is expected to precisely identify and define the molecular circuitry of a tumor, and unlike genomic platforms which require complex mathematical algorithms to report their inferential data, the assay is expected to directly identify which drug targets are active and which are not.
In September 2006, Theranostics Health, LLC (THX) was spun-out of George Mason University (GMU) and the laboratories of Dr. Lance Liotta and Dr. Emanuel Petricoin. Theranostics Health was formed with a singular focus: enabling the promise of personalized therapy to become a reality. THX is focusing on oncology, diabetes, inflammation, obesity, cardiovascular disease and infectious disease indications.
The cornerstone technology for THX is the Reverse Phase Protein Microarray (RPPA) platform that was invented and developed by Drs. Liotta and Petricoin. The technology is mature, and has been the subject /used in nearly 50 peer reviewed publications by the Liotta/Petricoin laboratory, and over 20 scientific presentations at AACR and ASCO, among others within the past 2 years. THX has a Master License with GMU for any past theranostic IP as well as all theranostic IP going forward. This includes specific IP around specific and simple predictive and prognostic biomarker assays as well as a new molecular fixative that rapidly preserves tissue at room temperature along with preservation of the phosphoproteome, proteome and transcriptome, formalin-like histology and IHC.
This platform provides the unique ability to quantitatively measure up to 250 phosphorylated proteins at once from as few as 10,000 cells. Since most targeted therapies act at the level of the protein and phosphorylation-driven cellular signaling, gene expression analysis is unable to provide a direct measurement of the actual drug target, whereas the RPPA platform is specifically designed to perform that function. The RPPA platform provides a combined level of dynamic range, sensitivity and multiplexing unmatched by any other protein-based technology, and enables THX to uniquely:
Quantitatively measure ongoing cellular signaling in human tissue biopsy specimens: RESULT: A patent-specific portrait of drug target activation for clinical trial and therapeutic stratification. The platform has already been successfully used in NCI-sponsored clinical trials and is being incorporated now into targeted therapy trials with several large pharmaceutical partners. THX is currently setting up its CAP/CLIA compliant laboratory.
Quantitatively measure ongoing cellular signaling of 100-250 phosphoproteins in cell culture (96-384 plate): RESULT: Lead compound screening for off-target effects and elucidation of unknown therapeutic mechanism of action. Over the past 2 years, the Liotta/Petricoin GMU laboratories have worked with several large pharmaceutical companies: cells were treated with their proprietary inhibitors, and signal pathway analysis performed in a blinded fashion and data were sent back. Based on the work, THX is now entering into collaborative agreements with a number of pharmaceutical companies for both preclinical and clinical trial work.
THX provides information that is distinctly unique and different from any other approach:
Multiplexed phosphoprotein and protein analysis: Up to 250 proteins measured from as few as 10,000 cells vs. 10-15 proteins from 250,000 cells for Suspension Bead Arrays
Quantitative and clinically reproducible assay: THX assay is quantitative with published inter and intra assay CVs of less than 10% with less than 1 cell equivalent vs. 20-30% CV for tissue microarray (a subjective assay that is routinely not quantitative). Moreover, the RPPA technology does not require antigen retrieval or employ sandwich immunoassays, greatly increasing number of endpoints that can be reproducibly and economically measured.
Direct assay for protein expression and phosphoprotein levels: The RPPA is a nanoliter-sized immunoassay that follows standard CLIA guidelines and is a direct and quantitative assay for protein function and drug target activity, information not possible through gene expression analysis.
Because THX provides direct analysis of protein function and drug target activity, which is entirely different than genomic approaches, the information is synergistic and complementary to gene expression and SNP data and can help realize and unlock the potential for these approaches and leverage the investment already made
Beginning in early 2008, Theranostics Health will begin working with physicians and hospitals to apply its technology to patient care by measuring the activity of the actual drug targets in a biopsy sample. Physicians can then utilize the information generated by Theranostics Health to improve clinical decision-making and tailor optimal personalized patient therapies based on the physician’s evaluation of the data. Importantly, the data provided by Theranostics Health to the physician will be easy to understand, both for the physician and for the patient. The data will not require complex analytic computer software to interpret results: there is no “black box”.
The Company is developing relationships and various collaborations with several pharmaceutical and biotech companies involving drug screening, data mining and clinical trial applications.
The Company is also working with medical device manufacturers to develop efficient tissue collection and transportation systems in addition to developing proprietary tissue fixative solutions that are significantly more effective than existing formalin based solutions.
About Our Technology
Our Company represents a new reality of molecular medicine whereby therapy is prescribed in a truly personalized and targeted manor: it is the merger of therapeutics and diagnostics. We believe that in the not so distant future, pharmaceutical development and clinical implication will require patient stratification and the emergence of companion diagnostics. In other words, an Rx/Dx relationship will be critical. Our technology can provide a functional read-out of cellular signaling pathways, the drug targets themselves, from just a few thousand cells taken from a needle biopsy. We also profile the cellular circuitry of the signaling pathways from cell culture cells treated with molecular inhibitors.
Reverse Phase Protein Microarray
The technological cornerstone for Theranostic Health is the Reverse Phase Protein Microarray (RPMA) technology, invented by company founders and George Mason University researchers, Dr Lance Liotta and Dr. Emanuel Petricoin. These scientists have published nearly 50 peer reviewed publications on this technology and its applications. These scientists have used this technology to uncover key signaling defects in a variety of human tumors such as breast, ovarian, lung, colorectal, prostate, lymphoma, and rhabdomyosarcoma, to name a few, which provide critical information about response, outcome prognosis, and what pathways are activated in these cancers.
Uniquely, the RPMA format provides the opportunity to screen clinical samples that are available in very limited quantities, such as biopsy specimens. Using this platform, Theranostics Health scientists can measure the activity of as many as 100 drug targets from just 5000 cells. The sensitivity of detection for the RPAs is such that low abundance phosphorylated protein isoforms can be measured from a spotted lysate representing less than 10 cell equivalents. This level of sensitivity combined with analytical robustness is critical if the starting input material is only a few hundred cells from a biopsy specimen. Since the reverse phase array technology requires only one antibody for each analyte, it provides a facile way for broad profiling of pathways where hundreds of phospho-specific analytes can be measured concomitantly.
Key technological components of the RPMA offer unique advantages over other existing multiplexed protein assay methods such as antibody arrays, suspension bead arrays, mass spectrometry based methods, and tissue microarrays
- The RPMA is one of the most sensitive protein detection technologies: as little as a few hundred molecules can be detected
- The RPMA provides quantitative measurements of the protein, not subjective scoring
- The inter and intra assay CV for the technology is less than 10% for clinical material
- RPMA is not hampered by antigen retrieval, a significant limitation for tissue arrays and immunohistochemical techniques.
- RPMAs only require a single class of antibody, and does not rely on sandwich type assays
- The RPMA can analyze proteins from any source: solid tissue, blood cells, serum, bone, spinal fluid, vitreous, etc.
- The RPMA unique sensitivity and requirement for only one antibody, provide for unmatched ability to analyze hundreds of signaling molecules at once, from only a few thousand cells.
Proteomics
What is proteomics?
Proteomics is the study of the expression, structure and function of proteins within cells, including the way they work and interact with each other. While DNA is the information archive, it is the proteins that do the work of the cell.
How are scientists using proteomics?
With the completion of the Human Genome Project, many researchers are now turning their attention to proteomics since it is the proteins that do the work of the cell and are the functional output of the genome. Scientists are very interested in proteomics because it gives a much better understanding of an organism than genomics. Since proteins play a central role in the life of an organism, proteomics is instrumental in discovery of biomarkers that indicate presence of a particular disease. Currently, researchers are studying the role that proteins play in identifying and treating diseases such as diabetes, obesity, heart disease, inflammatory disorders, infectious diseases and neurological disorders.
How is this different from genomics?
Genomics is the study of genes and their function. Genes contain the instructions for the production of proteins, which make up the structure of cells and direct their activities. Proteomics is often considered the next logical step in the study of biological systems, after genomics. While an organism's genome is rather constant, a proteome differs from cell to cell and constantly changes through its biochemical interactions with the genome and the environment. One organism has radically different protein expression in different parts of its body, different stages of its life cycle and different environmental conditions.
As most FDA approved drugs target protein function, not genes it is critical to be able to measure these actual drug targets to specifically tailor a therapy to address a disease.
What is theranostics?
The term theranostics describes the use of diagnostic testing to diagnose the disease, choose the correct treatment regime and monitor the patient response to therapy, all in the same biomarker. An example of a theranostic biomarker is the protein c-erbB2, which is overexpressed and activated in certain subpopulations of breast cancer patients. This biomarker correlates with the worse prognosis, but is also a target for therapy and guides the selection of HERCEPTIN, the first FDA approved molecularly targeted therapeutic.
What is a Proteomic Assay (or test)?
In general, molecular diagnostic companies use genomic- or pharmacogenomic-based approaches, while we have created a proteomic-based assay. A proteomic approach has several key advantages, but the most important advantage of a proteomic approach is its ability to directly measure and profile a drug target. We believe proteomics can accurately predict protein function or activity, whereas other methodologies cannot define a cell’s working machinery or decipher its communication network. These key advantages of our methodology are expected to provide information which will enable physicians and pharmaceutical companies to more effectively prescribe and develop drugs that are specifically designed to hit the molecular profile of a patient’s disease.
We believe that our protein based assay will have significant advantages over genomic type tests which frequently use complex algorithms to predict probabilities. We believe these advantages include:
• specifically identify the defective pathways in breast and other solid tumor cancer patients, not solely predict a response to chemotherapy;
• specifically identify specific proteases, protein kinases, and hormones;
• specifically suggest a therapy to all patients regardless of chemosensitivity;
- providing a simple and easy to interpret result compared to a complex result generated by some genomic based tests, which can require sophisticated computer algorithms to interpret data.

Healthcare Professionals
Beginning in the first quarter of 2008, we plan to expand our target market to include physicians and hospitals that prescribe therapy to cancer patients.
Our assay represents a breakthrough technology that is expected to provide users with a clear and accurate analysis of the wiring diagram of a patients cancer cells, and define which pathways are specifically altered and activated. We believe that it will identify the specific pathways that are the drug targets themselves.
For patients and physicians, the assay is intended to provide the information necessary to tailor and customize chemotherapy to the unique molecular profile of each patients tumor. For the pharmaceutical company, our assays are intended to provide critical information as to drug activity, selectivity and specificity. The assays are also meant to provide for the accurate identification of those patients most likely to respond to their specific drug, thus decreasing the time and cost of clinical trials. For third party payors such as insurance companies, the assays will reduce costs because the therapy will be tailored, rather than prescribed on a "trial and error" basis. Unlike existing genomic diagnostic platforms, our assay using proprietary diagnostic tools is expected to precisely identify and define the molecular circuitry of a tumor, and unlike genomic platforms which require complex mathematical algorithms to report their inferential data, the assay is expected to directly identify which drug targets are active and which are not.
We believe our test has several distinct advantages:
less treatment toxicity due to the accuracy of the technology;
lower treatment development costs and faster time to market for pharmaceutical companies;
individualized therapy for higher therapeutic efficacy and lower treatment costs;
a diagnostic platform that can be adapted to assess other major diseases; and
less complex results than genomic assays and different regulatory pathways than genomic or functional genomic platforms.
we invented and developed the assay that can precisely analyze the cellular circuitry and elucidate the wiring diagram of a cancer cell or any disease cell. The platform has been extensively validated as demonstrated by their extensive publication list of peer-reviewed publications, and we believe the assay can be reproduced for use in a variety of cancers including lung, breast, ovarian, colorectal, pancreatic, prostate, renal, multiple myeloma, childhood sarcomas, and others.
We will eventually seek to apply the assay as a theranostic tool for diabetes, obesity, heart disease, inflammatory and infectious diseases, and neurological disorders. It is our intention to develop this technology and pursue its clinical introduction in the near future.
