Health Discovery Corporation Announces Successful Clinical Trial Results for New Molecular Diagnostic Test for Prostate Cancer



    Health Discovery Corporation ("HDC")

    (OTCBB: HDVY) today announced the successful clinical trial results for

    HDC´s new molecular diagnostic test for

    prostate cancer licensed exclusively to Clarient (Nasdaq:CLRT), in which

    HDC will receive a 30 percent royalty based on reimbursements received

    by Clarient from third parties.
    The initial clinical validation study recently completed at Clarient

    from prostate tissues obtained in collaboration with MD Anderson Cancer

    Center demonstrated a very high success rate for identifying the

    presence of Grade 3 or higher prostate cancer cells (clinically

    significant cancer) in prostate cancer tissue. The new molecular

    diagnostic test achieved a Sensitivity of 100% meaning that the test

    correctly identified genomic evidence of prostate cancer cells in every

    tissue specimen known to be positive for prostate cancer. The test also

    demonstrated a very high success rate for correctly identifying those

    prostate specimens that did not have prostate cancer as being negative

    for prostate cancer and achieved a Specificity of 80% for identifying

    the non-cancer tissues, which included normal and benign prostatic

    hypertrophy (BPH) tissue, as not having genomic evidence of cancer.
    In the United States alone there are over 1 million prostate cancer

    tissue biopsy procedures performed annually. Approximately 25% of these

    tissue biopsies are reported "positive" indicating the presence of prostate cancer. The other 75% of prostate

    cancer tissue biopsies are reported as "negative" for the presence of cancer. However, one-third of the men with prostate

    cancer tissue biopsies that are reported as "negative" for prostate cancer (roughly 25%) actually do have prostate cancer that

    was missed by the first biopsy (False Negative). These men actually have

    prostate cancer that was missed by the initial tissue biopsy for a

    variety of reasons. Health Discovery Corporation´s

    prostate cancer molecular diagnostic test is a genomics based test

    discovered using HDC´s patented SVM and

    SVM-RFE pattern recognition technology. This prostate cancer test is

    based on a unique combination of 4 genes that accurately identify the

    presence of Grade 3 or higher (clinically significant cancer) prostate

    cancer cells in prostate tissue.
    HDC and Clarient will now move to phase two of the clinical trial

    process to increase the number of specimens tested in order to achieve

    the statistical significance necessary to validate these very successful

    initial results. Once the next phase of clinical testing is completed

    The Companies will begin the commercialization process. Assuming the

    data continues to support these initial findings, it is possible that

    the product could be made available for clinical use by late Q3 of 2008

    under the current CLIA regulations.
    "We are thrilled with the results of this

    clinical trial and look forward to the commercial launch of this new

    prostate cancer test with Clarient," stated

    Stephen D. Barnhill, M.D., Chairman and CEO of Health Discovery

    Corporation. "The success of this clinical

    trial also demonstrates that HDC, using our patented SVM and SVM-RFE

    technology, can develop new molecular diagnostic tests from conception

    of the idea through clinical discovery and validation of unique genomic

    signatures that can be commercialized as new molecular diagnostic tests.

    Our patent protected discovery method allows to us to develop molecular

    diagnostic tests that are free of outside intellectual property rights

    and thereby allows HDC to fully patent protect our discovery. We are

    currently duplicating this process to develop new molecular diagnostic

    tests in a variety of other cancers."
    Dr. Barnhill continued "We are looking

    forward to having HDC´s new prostate cancer

    test commercialized like similar molecular diagnostic tests based on

    unique gene expression profiles such as OncotypeDX from Genomic Health

    Inc. (NasdaqGM:GHDX) and MammaPrint from Agendia."
    "The results of this clinical trial

    demonstrating genomic evidence of the presence of prostate cancer in

    prostate cancer tissue with 100% accuracy is a remarkable accomplishment," stated Dr. Herbert Fritsche, Professor of Laboratory Medicine and Chief

    of the Clinical Chemistry Section at The University of Texas, M.D.

    Anderson Cancer Center in Houston, Texas. "Health

    Discovery Corporation´s ability to develop

    state-of-the-art molecular diagnostic tests for cancer combined with

    Clarient´s ability to successfully

    commercialize these tests can provide a significant benefit to cancer

    patients and their physicians."
    Savannah-based Health Discovery Corporation (OTCBB: HDVY) is uniquely

    positioned in the field of pattern recognition technology. Through the

    application of its patent protected technology, HDC is a

    biology-oriented biomarker discovery company providing all aspects of

    First-Phase Biomarker Discovery(sm). The Company´s SVM and FGM pattern

    recognition tools have significant application potential in other

    sizable commercial markets such as radiology, financial markets

    Internet search and spam, homeland security, and other areas where

    analysis of large volumes of complex data is required.
