ERG Monoclonal Antibody [9FY] Patent issued to the Uniformed Services University of the Health Sciences Center for Prostate Disease Research & Biocare Medical

Concord, CA, August 21, 2014 – The Henry M. Jackson Foundation for the Advancement of Military Medicine, Inc. has been awarded a patent in the United States (Patent No: US 8,765,916 B2) and Europe for ERG monoclonal antibodies. The patent is pending in Australia, Canada and Japan. ERG mouse antibody 9FY is a rigorously characterized antibody for its specificity of the ERG protein detection among the closely related members of the ETS transcription factor family in biological specimens.

ERG gene fusions are among the most validated cancer genome defects present in half of all prostate cancers in western countries. The 9FY clone provides robust and specific detection of the ERG protein, the product of ERG fusions in prostate cancer specimens. Based on the 99.9% specificity of the 9FY, the utilization of this antibody may aid in diagnosis of prostate biopsies with inconclusive results to ascertain the diagnosis of prostatic carcinoma. Repeat biopsies may only be necessary when ERG positive PIN is identified as there is a 97% chance of finding an ERG positive prostatic carcinoma.

ERG [9FY] may have diagnostic utility for prostate cancer, acute myeloid leukemia and vascular tumors.  It is helpful in minute foci of prostatic acinar carcinoma in prostate biopsy specimens. 9FY can accurately discriminate between ERG positive prostate cancer cells and lymphocytes and other cell types, helping to establish prostatic origin in metastatic carcinomas to lymph nodes or other metastatic sites. It may also be used to diagnose tumors of endothelial origin, such as angiosarcoma, variants of hemangioma, Kaposi sarcoma, and staging AML lymphoid tumors. ERG may also detect or confirm vascular invasion and assess microvessel density in tumors other than prostatic carcinomas or cells of endothelial origin, as 9FY stains blood and lymphatic endothelial cells.

Biocare Medical, LLC, is the exclusive distributor of the ERG [9FY] mouse monoclonal antibody for in-vitro diagnostics by immunohistochemistry staining and for research purposes. There are approximately 1 million biopsies per year and about 250,000 new prostate cancers per year in the United States. Approximately 10% are inconclusive biopsies and may require confirmation by ERG staining resulting in 100,000 or more cases per year. The availability of ERG data in biopsies will also be useful in future ERG-targeted treatment of prostate cancer, such as the ongoing clinical trial of PARP inhibitors already in use for triple negative breast cancers.
