Aethlon Medical Announces Exosome Detection Assay

July 7, 2010

SAN DIEGO, July 7 /PRNewswire-FirstCall/ — Aethlon Medical, Inc. (OTC Bulletin Board: AEMD), the pioneer in developing therapeutic filtration devices to address infectious disease and cancer, announced today that it has filed a provisional patent on behalf of its wholly owned subsidiary Exosome Sciences, Inc. (ESI), relating to the development of an assay that will allow researchers to detect exosomes in blood and other fluids.

Beyond the potential therapeutic benefits of eliminating immunosuppressive exosomes from circulation, researchers recognize that exosomes represent an important diagnostic target to determine progression and prognosis of both cancers and infectious disease conditions. However, the availability of functional assays that specifically detect exosomes is limited. At present, exosomes are generally characterized and purified by size chromatography and general protein assay, not by chemical structures specific to the exosome. The company’s Enzyme Linked Lectin Specific Assay (ELLSA) is analogous to the well established enzyme linked immunosorbent assay (ELISA), and has been designed to bind specifically to carbohydrate structures common to exosomes, but not to healthy human cellular components. Each ELLSA plate allows for up to 96 exosome detection tests. Further analysis of the captured exosomes is possible through detection molecules such as antibodies linked to a specific biomarker on the exosome. “Our proprietary assay provides the potential for a previously unrecognized revenue stream and further augments the relationships we have established with thought leaders from the oncology field,” stated Aethlon Chairman and CEO, Jim Joyce.

About Aethlon Medical

At Aethlon Medical, we create revolutionary devices to address infectious disease and cancer. Our devices are designed to be novel platform solutions that fill therapeutic voids or aid in disease diagnosis and monitoring.

Our Hemopurifier® is the first medical device to selectively target the removal of infectious viruses and immunosuppressive proteins from the entire circulatory system. We recently discovered that our Hemopurifier® captures tumor-secreted exosomes that suppress the immune system of those afflicted with cancer. Prior to this discovery, a therapeutic strategy to directly inhibit or reverse the immunosuppressive destruction caused by exosomes did not exist in cancer care. By eliminating this mechanism, we believe our Hemopurifier® can fill an unmet clinical need and provide the benefit of an immune-based therapy without adding drug toxicity or interaction risks to established and emerging treatment strategies.

Human studies have documented the ability of our Hemopurifier® to safely reduce viral load in both Hepatitis-C virus (HCV) and Human Immunodeficiency Virus (HIV) infected patients without the administration of antiviral drugs. However, our initial clinical and commercialization focus is to establish our Hemopurifier® as an adjunct therapy to enhance the benefit of both infectious disease and cancer treatment regimens. In this regard, we plan to commercialize our Hemopurifier® in India as we advance our clinical strategies in the United States and the European Union. In vitro studies conducted by government and non-government research institutes have also verified that our Hemopurifier® has broad-spectrum capabilities against bioterror and emerging pandemic threats. These studies have confirmed the capture of Dengue Hemorrhagic Virus, Ebola Hemorrhagic Virus, Lassa Hemorrhagic Virus, West Nile Virus, H5N1 Avian Influenza Virus, 2009 H1N1 Influenza Virus, the reconstructed Spanish Flu of 1918 Virus, and Monkeypox Virus, which serves as a model for human Smallpox infection.

As a therapeutic device, the Hemopurifier® provides us with a pipeline into four significant market opportunities:

  1. Cancer: A treatment candidate to improve patient responsiveness to established cancer therapies by removing immunosuppressive exosomes from circulation.
  2. Hepatitis-C Virus (HCV): As an adjunct therapy to accelerate viral load reduction at the outset of standard of care drug regimens.
  3. Human Immunodeficiency Virus (HIV): Provides a potential therapeutic option for HIV-infected individuals to manage disease progression once they become resistant to antiviral drug regimens.
  4. Bioterror and Pandemic Threats: Represents the most advanced broad-spectrum strategy to address untreatable bioterror and emerging pandemic threats.

The Hemopurifier® is an expansive multi-patented platform technology whose mechanism of action can be leveraged to provide therapeutic, diagnostic, and biomarker discovery solutions. As a therapeutic, the Hemopurifier® is a single-use disposable cartridge designed for implementation within the established infrastructure of dialysis machines and other blood circulatory pumps already located in hospitals and clinics worldwide.

In design, our Hemopurifier® is a selective filtration device containing affinity agents that tightly bind to high-mannose structures unique to the surface of exosomes produced by cancer and glycoproteins residing on the envelope of viruses. These agents are immobilized around approximately 2800 porous hollow fibers that run the interior length of our device. The resulting design provides us the novel ability to separate both exosome and viral targets away from blood cells so they can then be selectively and permanently removed from the circulatory system. In application, blood circulation is established into the Hemopurifier® via a catheter or other blood access device. Once blood flow has been established, treatment benefit is immediate as the entire circulatory system can pass through the Hemopurifier® in as little as 15 minutes.

Our wholly owned subsidiary, Exosome Sciences, Inc. (ESI) is focused on the development of exosome-targeted products and services that improve cancer diagnosis, provide post-treatment cancer surveillance, and aid in the discovery of biomarkers that allow doctors to optimize patient therapy.
