Aethlon Medical, Inc., a medical device company, focuses on creating devices for the treatment of cancer, infectious diseases, and other life-threatening conditions. It develops Aethlon Hemopurifier, a medical device that targets the elimination of circulating viruses and tumor-secreted exosomes that promote cancer progression. The company's Aethlon Hemopurifier addresses antiviral drug-resistance in hepatitis-C virus and human immunodeficiency virus infected individuals; serves as a countermeasure against viral pathogens not addressed by drug or vaccine therapies; and represents the therapeutic strategy to address cancer promoting exosomes. It is also developing exosome-based products to diagnose and monitor neurological disorders and cancer; and a therapeutic device to reduce the incidence of sepsis, a fatal bloodstream infection that often results in the death of combat-injured soldiers. The company was founded in 1991 and is based in San Diego, California.
