James A. Joyce
Co-founder, Chairman, and CEO Inventor
James “Jim” Joyce has more than two decades of public company CEO and Corporate Board leadership experience. He is also an inventor or co-inventor of ~20 pending or issued patents, including those underlying ImmunePrep™, ChemoPrep™, ChemoPure™ and Sigyn Therapy™.
Prior to establishing Sigyn Therapeutics, Mr. Joyce was the founder and former Chairman and CEO of Aethlon Medical, a therapeutic technology company that he navigated from single shareholder start-up to Nasdaq-traded Company with 8000+ shareholders. During his tenure at Aethlon, Mr. Joyce oversaw the development of the Hemopurifier®, a first-in-class blood purification technology to address life-threatening viruses and cancer-promoting exosomes. Under his leadership, the Hemopurifier® became the first therapeutic candidate to be awarded two FDA “Breakthrough Device” designations and was the first and only device to receive “Emergency Use Authorization” (EAU) approval from the FDA, Health Canada, and the Government of Germany to treat Ebola virus. Time Magazine named the Hemopurifier® one of the “11 Most Remarkable Advances in Healthcare” and designated the device to its “Top 25 Best Inventions” award list.
Under Mr. Joyce’s leadership, Aethlon Medical was awarded multiple U.S. government contracts, including a contract with the National Cancer Institute (NCI) and two contracts with the Defense Advanced Research Projects Agency (DARPA), a U.S. Department of Defense (DOD) entity. While at Aethlon, Mr. Joyce also led the completion of five human clinical studies, the closing of approximately $100 million of equity financings, and the establishment of preclinical and clinical collaborations with more than twenty government and non-government research institutes.
Based on the use of the Hemopurifier® to treat HIV and Hepatitis-C infected individuals in India, Mr. Joyce was the recipient of the “Spirit of India Award” sponsored by the Bill & Melinda Gates Foundation and awarded each year by the American India Foundation to the American business leader who has demonstrated a commitment to accelerate social and economic change in India.
Mr. Joyce testified before Congress and lobbied Capitol Hill to promote the use of medical devices as candidate treatment countermeasures against emerging bioterror and pandemic threats, which contributed to expanding the countermeasure definition to be inclusive of medical devices under U.S. law. Previously, a treatment countermeasure was defined solely as a drug or vaccine. Subsequently, medical device therapies were among the first to receive Emergency-Use Authorization from FDA during the Ebola and COVID-19 outbreaks.
Mr. Joyce was also the founder and former Executive Chairman of Exosome Sciences, Inc. (ESI), a company that focused on the discovery of exosomal biomarkers. Inspired by the death of a former teammate, Mr. Joyce established a collaboration with the Boston University CTE Center to test his hypothesis that circulating exosomes transporting tau protein cargos (exosomal tau or TauSome) might provide a basis for a non-invasive blood test to diagnose or monitor neurological tauopathies, including chronic traumatic encephalopathy (CTE) and Alzheimer’s disease. As a result, ESI was invited to participate in the first NIH funded clinical study of CTE, which revealed exosomal tau levels to be approximately 9x higher in 78 former NFL players as compared to same age group control subjects. The study results (co-authored by Mr. Joyce) were published in the Journal of Alzheimer’s Disease. In a follow-on study, Exosome Sciences reported exosomal tau levels to be similarly elevated in diagnosed Alzheimer's patients. Researchers at Johns Hopkins would subsequently report exosomal tau to be the basis for a blood test that could diagnose Alzheimer's disease up to four years before first symptoms.
Prior to founding Aethlon Medical and Exosome Sciences, Mr. Joyce operated James Joyce & Associates. He was the founder and former CEO of Mission Labs, Inc. and a principal at London Zurich Securities. Upon graduating from the University of Maryland, Mr. Joyce was first employed as a member of the Denver Broncos Football Club of the National Football League.

The IMPACT system was comprised of multiple cartridges and designed to reduce the presence of inflammatory cytokines from human blood plasma. As a Clinical Perfusionist, Craig has conducted more than 4,000 extracorporeal procedures, including adult and pediatric cardiopulmonary bypass, cardiac assist devices, ECMO (artificial lung), vascular access catheter systems, and continuous renal replacement therapy.
