Aethlon Medical Announces Publication Demonstrating Novel Long COVID Biomarker and Potential Therapeutic Target for the Hemopurifier®
Rhea-AI Summary
Aethlon Medical (Nasdaq:AEMD) announced peer-reviewed research identifying a novel Long COVID biomarker and target for its Hemopurifier® device. The study found significantly increased mannosylated extracellular vesicles (EVs) in Long COVID patients, which were captured using the same Galanthus nivalis agglutinin (GNA) affinity resin used in the Hemopurifier.
Key findings include roughly two-fold higher mannose-positive EVs in Long COVID, successful capture of disease-associated small EVs, significant reduction of seven immune-related microRNAs after GNA resin treatment, and pathway analysis implicating JAK-STAT, VEGF, PI3K, and estrogen signaling. The results support EVs as a potential therapeutic target and provide a translational framework for future Hemopurifier studies in Long COVID.
Positive
- Peer-reviewed Long COVID study identifies mannosylated extracellular vesicles as potential Hemopurifier® target
- Long COVID patients showed approximately two-fold higher mannose-positive extracellular vesicle levels
- Disease-associated small extracellular vesicles captured using Hemopurifier’s GNA affinity resin
- GNA affinity resin treatment significantly reduced seven immune-related circulating microRNAs
- Pathway analysis linked EV changes to JAK-STAT, VEGF, PI3K, and estrogen signaling in Long COVID
- Findings support Hemopurifier® as a potential platform technology across multiple disease areas
Negative
- None.

Peer-reviewed study identifies altered extracellular vesicles in Long COVID and provides additional scientific rationale for evaluating the Hemopurifier® as a potential treatment
The study, conducted in collaboration with investigators from the University of
"The publication of this study contributes to the scientific understanding of the biological mechanisms underlying Long COVID while strengthening the rationale for evaluating the Hemopurifier in this significant area of unmet medical need," said Jim Frakes, Chief Executive Officer and Chief Financial Officer of Aethlon Medical. "While the Company's current resources and primary focus remain dedicated to advancing our Australian oncology clinical trial, these findings provide additional translational evidence supporting future preclinical and clinical studies designed to determine whether removal of these circulating extracellular vesicles may benefit patients with Long COVID. More broadly, we believe these findings reinforce the potential of the Hemopurifier as a platform technology with potential applications across multiple disease areas. We believe there exists a 'pipeline within a single device.'"
Key Findings
Among the study's principal findings:
- Patients with Long COVID had approximately two-fold higher levels of mannose-positive extracellular vesicles than individuals who recovered fully following COVID-19 infection.
- Small extracellular vesicles carrying disease-associated glycosylation patterns were successfully captured using GNA affinity resin, the active binding component of the Hemopurifier.
- GNA affinity resin treatment significantly reduced seven circulating microRNAs associated with immune regulation and inflammatory signaling.
- Computational pathway analysis suggested modulation of several biologically relevant signaling pathways implicated in Long COVID, including JAK-STAT, VEGF, PI3K, and Estrogen signaling.
- The findings help establish a mechanistic link between disease-associated extracellular vesicles and the Hemopurifier's lectin-based capture technology.
The research analyzed plasma samples from participants enrolled in UCSF's Long-term Impact of Infection with Novel Coronavirus (LIINC) study.

About Aethlon and the Hemopurifier®
Aethlon Medical is a medical therapeutic company focused on developing the Hemopurifier, a clinical-stage immunotherapeutic device that is designed to combat cancer and life-threatening viral infections, and for use in organ transplantation. In human studies, the Hemopurifier has demonstrated the removal of life-threatening viruses, and in pre-clinical studies, the Hemopurifier has demonstrated the removal of harmful EVs from biological fluids, utilizing its proprietary lectin-based technology. This action has potential applications in cancer, where EVs may promote immune suppression and metastasis, and in life-threatening infectious diseases. The Hemopurifier is a U.S. Food and Drug Administration (FDA) designated Breakthrough Device indicated for the treatment of individuals with advanced or metastatic cancer who are either unresponsive to or intolerant of standard of care therapy, and with cancer types in which EVs have been shown to participate in the development or severity of the disease. The Hemopurifier also holds an FDA Breakthrough Device designation and an open Investigational Device Exemption (IDE) application related to the treatment of life-threatening viruses that are not addressed with approved therapies.
