Company Description
Aethlon Medical, Inc. (Nasdaq: AEMD) is a clinical-stage medical device company headquartered in San Diego, California. According to the company’s public disclosures, Aethlon is a medical therapeutic business focused on developing products to treat cancer and life-threatening infectious diseases. Its work centers on the Hemopurifier, an investigational extracorporeal device designed to selectively remove pathogenic targets from circulation in biologic fluids.
Core technology: the Hemopurifier device
Aethlon describes the Hemopurifier as a clinical-stage immunotherapeutic device intended to combat oncology and infectious disease indications. Company materials state that the Hemopurifier is designed to remove enveloped viruses, fragments of viruses, and tumor-derived extracellular vesicles (EVs) from the bloodstream. The device is used with a blood pump outside the body and combines plasma separation, size exclusion, and affinity binding via a proprietary plant lectin resin that targets mannose-rich surfaces found on EVs and viral proteins.
In human and preclinical studies referenced by the company, the Hemopurifier has demonstrated removal of life‑threatening viruses and harmful EVs from biological fluids. Aethlon reports that this mechanism has potential applications in cancer, where EVs are believed to contribute to immune suppression, metastasis, and resistance to therapies, and in life‑threatening viral infections.
Regulatory designations and development stage
Aethlon states that the Hemopurifier holds a U.S. Food and Drug Administration (FDA) Breakthrough Device Designation for two indications:
- Treatment of individuals with advanced or metastatic cancer who are unresponsive to or intolerant of standard‑of‑care therapy, in cancer types where EVs have been shown to participate in disease development or severity.
- Treatment of life‑threatening viruses that are not addressed with approved therapies.
The company also notes that it has an open Investigational Device Exemption (IDE) related to treatment of life‑threatening viruses. Because the Hemopurifier is investigational, Aethlon emphasizes in its communications that the device’s safety and effectiveness have not been established and that observations from early feasibility studies should not be interpreted as evidence of clinical benefit beyond study parameters.
Oncology program and clinical research
Aethlon reports ongoing clinical work in oncology. In Australia, the Hemopurifier is being evaluated in a safety, feasibility, and dose‑finding trial in patients with solid tumors who have not responded to anti‑PD‑1 therapies such as pembrolizumab or nivolumab. The study design includes sequential cohorts receiving escalating numbers of Hemopurifier treatments over a one‑week period, with the primary endpoint focused on safety. Exploratory objectives include assessing whether reducing EV concentrations may support the body’s immune response against tumor cells.
Company updates describe early observations in the first cohort, including decreases in large EVs (microvesicles), platelet‑derived EVs, and subsets of EVs carrying PD‑L1 in some participants after a single Hemopurifier treatment, as well as changes in selected microRNAs and T‑cell subsets. Aethlon notes that these findings are based on a small number of patients, are descriptive rather than statistically powered, and cannot be correlated with clinical efficacy at this stage. The company indicates that additional cohorts are intended to help determine whether such changes are reproducible and whether there is a dose–response relationship.
Infectious disease and Long COVID research
Beyond oncology, Aethlon highlights research in life‑threatening viral infections and conditions associated with EVs, including Long COVID. The company states that the Hemopurifier has been studied in severe acute COVID‑19, where it demonstrated removal of EVs and decreases in certain microRNAs in a human case. Preclinical work described by Aethlon shows that its GNA affinity resin can bind EVs in plasma samples from individuals with Long COVID and deplete EV‑associated microRNAs linked to inflammatory pathways.
Aethlon has collaborated with the University of California San Francisco Medical Center Long COVID clinic to analyze plasma samples from Long COVID participants and recovered controls. According to company communications, these studies found elevated levels of large and small EVs in Long COVID samples, increased mannose‑positive EVs, and removal of EVs and selected microRNAs by the GNA affinity resin. The company presents these data as support for further investigation of the Hemopurifier in Long COVID and other EV‑associated conditions, while noting that the device remains in the research and development stage for these uses.
Intellectual property and biodefense focus
Aethlon describes itself as focused on unmet needs in health and biodefense. Public disclosures indicate that the company is building a patent portfolio around the Hemopurifier and its applications. For example, Aethlon has announced U.S. and European patents directed to use of the Hemopurifier in treating Long COVID and COVID‑19‑associated coagulopathy, as well as multiple patents related to removal of exosomes, microvesicular particles, and COVID‑19 viral particles and associated exosomes. The company views these protections as strengthening its intellectual property position around EV and virus removal in areas of significant medical need.
Capital markets and listing status
Aethlon Medical is incorporated in Nevada and its common stock trades on the Nasdaq Capital Market under the symbol AEMD. The company has reported that it is a smaller reporting company under U.S. securities regulations. Recent SEC filings and press releases describe registered offerings and private placements of common stock, pre‑funded warrants, and common stock purchase warrants, with proceeds intended for working capital, clinical trial expenses, research and development, capital expenditures, and general corporate purposes.
Company filings also detail actions taken to maintain compliance with Nasdaq listing requirements, including a reverse stock split and subsequent confirmation from Nasdaq that Aethlon regained compliance with the minimum bid price rule. As of the latest disclosures provided, Aethlon states that it remains listed on the Nasdaq Capital Market.
Business model and risk profile
Based on its public statements, Aethlon’s business model is centered on advancing the Hemopurifier through clinical development in oncology and infectious diseases, supported by preclinical research and collaborations in areas such as Long COVID. As a clinical‑stage company with an investigational device, Aethlon highlights in its filings that it faces risks typical of early‑stage medical device developers, including dependence on successful clinical trials, regulatory approvals, manufacturing capability, and access to additional capital.
FAQs about Aethlon Medical (AEMD)
- What does Aethlon Medical do?
Aethlon Medical is a clinical‑stage medical device company that states it is focused on developing therapeutic devices to treat cancer and life‑threatening infectious diseases. Its lead technology is the Hemopurifier, an investigational extracorporeal device designed to remove enveloped viruses, viral fragments, and tumor‑derived extracellular vesicles from circulation. - What is the Hemopurifier?
